This report contains the graduation project of Linde de Jonge in collaboration with Paviljoen 3, and aims to find a solution to reducing the eco-footprint of existing homes, by combining solar panels, green roofs and heat pumps in a modular fashion to be adaptable to the specific requirements of each household and complement the working of each individual system. Method User research, market analysis, creative sessions and observational studies have been implemented to support the iterative process towards a solution. The creative process was divided in three cycles. The focus of the first cycle was to find a solution with high feasibility for the company, by combining products on the market and adding small but crucial design intervention to create a unified system for flat roof surfaces. The second cycle aimed to create a solution suitable for tiled roofs, which is exceedingly common in the Netherlands, yet thus far incompatible with a green roof. The focus was on creating a solution which would enhance the exterior of the building, to increase the desirability of the design (an opportunity based on client research). The two cycles resulted in two concepts with a very opposing solution approach. These concepts were presented to the company and a selection was made. This selected concept was the start of the third cycle. In this cycle, the feasibility is established by detailing the embodiment of the system. Furthermore, the viability is illustrated by a future development roadmap. Design This project’s main challenge can be summarized as finding the balance between: 1. introducing an entire roof-system to market; 2. without losing the flexibility in the wide range of products (PV, heat pump or green roof) available to fit the variance in client and household needs; 3. and with the least amount of in-house produced parts to fit the company’s resources. The solution of this project is an entire roof-system, consisting of market available components and components proposed to be developed and manufactured by the company Paviljoen 3, which are implemented into the system according to distinct development phases. By combining existing products on the market, solely introducing components which are crucial for the viability of the roof-system and separating the innovation of system’s components into separate phases, this solution diffuses the investment costs for P3, while enabling them to acquire empirical insights concerning the system, which they can apply in further system development. They can have intensive prototyping and experience using market-bought products, before they invest in launching their own product. The design cycle ends with a final prototype of the developed components, and a company evaluation. The report concludes with a list of recommendations for the company to pursue further concept development.

In the future, healthcare becomes more challenging to reach and less personal. The workload for specialists is increasing (Rossen, 2018), the current health path for patients is extended and long (van Tongerloo, 2019) and more general practitioners do not want to have their own practice which results in lower accessibility (Smit, 2019). Besides, the computer is often in-between the communication of the patient and the specialist when entering the consultation room (Voormolen, 2013). These developments are opposite to the ones of the on-demand society we are currently living in: people have personalised information on-demand and expect companies to understand their needs and wants on the spot (Solis, 2017). However, healthcare is, at this point, behind. The Erasmus MC has noticed this gap, and therefore, the Erasmus MC wants to implement the value-based healthcare strategy. Within this strategy, the Erasmus MC wants to focus more on the patient experience and the patient’s participation in decision making during the consultation (Kimpen, 2019). So how to improve this patient experience, to align the consultation with the value-based healthcare system? Within this project, the current barriers of positive patient experience, before, during and after the consultation, are defined by an extensive literature and user study. The concept proposal, the renewed patient portal of the Erasmus MC, aims to translate these barriers into enablers of a positive patient experience. The renewed patient portal exists out of three elements: improve the patient’s knowledge around a disease by giving personalised information (1), track the patient’s data to get more personalised care (2), and prepare the consultation to start the conversation to the point (3). A case study for diabetes type 1 patients, focussed on the second element of the renewed patient portal, shows a tangible example of how the patient’s data can be used to give more personalised and on-demand care. The final deliverable of the case study is Mijn Erasmus I.D., a visual representation of the patient’s mental and physical data. Mijn Erasmus I.D. is a digital patient I.D. that is accessible via a platform for the patient and an interactive screen in the consultation room. An extensive validation study has proven that Mijn Erasmus I.D. turns all the found barriers into enablers of the positive patient experience. The aimed longterm effect is to create a more in-depth and personal conversation, within the same amount of time. Mijn Erasmus I.D. allows the specialists to understand the perspective of the patient better within the given amount of time by gathering the patient’s information up-front. An understanding of the patient’s perspective contributes to better health outcomes at a physical, psychological and social level (Street, Makoul, Arora, & Epstein, 2009). The research, the design goal, the concept proposal (the renewed patient portal) and the case study (Mijn Erasmus I.D.) are evenly important to inspire healthcare for future innovation.

The business wide objective of Philips regarding the transition to the circular economy is among others, that 15% of the total revenue should be from circular revenue from products and services by 2020.Patients with Obstructive Sleep Apnea Syndrome use a CPAP machine at home to keep their airways open during sleep. The Sleep & Respiratory Care business of Philips creates these products and needs to reach the same general sustainability targets related to circular revenue. The masks and headgear are medical consumables and are replaced on a regularly basis according to the insurance’s reimbursement cycle. The products are not always broken when they are replaced and the current headgear design can not be recycled. Next to this, the products are provided to the patient through multiple stakeholders whereby Philips has low control over the material flow. Therefore, in this project the products are redesigned to become ‘circular ready’ and a roadmap for the implementation of new circular propositions have been created. A Life Cycle Assessment tool is created to assess the life cycle of the current product system and compare this to new designs and scenarios in an iterative way. The propositions are based on the three different circular strategies: Slowing resource loops, Closing resource loops and material efficiency. The new design has been optimized for a longer lifetime and easier cleaning ritual, as a first short term circular strategy. The new headgear will be made with a knitting production technique and two arms that slide in this piece. This design is based on the just released headgear with arms design of Philips. This ensures comfort and more stability for the user. It is recyclable and is material efficiently produced. The business model is redesigned in combination with a new procurement scenario that can be included in the already existing DreamMapper app. This is done to link the replacement to the performance of the products and stimulate a longer product life. Furthermore, a recycling and future reverse logistic scenario has been created. The silicone of the mask can be taken back and sold for recycling. The user can sent the products through the normal mail with the help of information from the app. The headgear can be recycled through the municipal textile recycling stream that should be widely implemented in Europe by 2025. All the proposition parts are designed with the eye on the future and technology trends. The future in CPAP supplies are custom made products, supported by digital production techniques and the 3d face scan software. This can enable super local production. From the final life cycle assessment of the different proposition parts can be concluded that these lower the kg CO2 emissions. The project results are expected to be highly feasible as already existing resources and infrastructures are used for the new proposition. The holistic design approach and solution, including the clear steps and advantages for the 4 key ingredients have inspired the business. The next steps are already taken.

Healthcare is a major contributor to the negative effects on the environment, leading to adverse effects on the physical and mental health of people globally (IPCC, AR6). The Dutch healthcare sector alone is responsible for 7-8% of the national carbon footprint, 4,2% of total waste and 13% of raw material extraction (Steenmeijer et al. 2022). This project was set up in three main parts to identifying opportunities for sustainable interventions in colonoscopy procedures for the EMC gastroenterology department. Throughout the project, a human-centered design approach was maintained. Research was done in literature on sustainability in healthcare and environmental impact of endoscopy, empirical context research and material flow analysis (MFA) in the form of a waste audit. Based on circular strategies Reduce and Recycle, the research outcomes were synthesized into an intervention that aligns to the EMC's policy statements for sustainability: - reduce waste with 10% - increase recycling with 20% Waste audit data was used as an input for co-creating with endoscopy nurses, where the focus was put on retrieving plastics from GMW because of their significant contribution to total emissions when incinerated (López-Muñoz et al., 2023). Ideation was done in co-creation sessions to solve the problem of integrating waste segregation inside the complex environment of a colonoscopy treatment room for current system boundaries. Outcomes While it is ideal to implement higher R-strategies for designing out waste early on in the process, waste cannot be ruled out completely. Therefore, implementing a waste segregation system in the endoscopy treatment room presents an opportunity to enhance waste management in EMC and align with sustainability goals. The proposal is a demonstration rather than a product concept, to show small incremental changes within the current system boundaries can help achieve the EMC goals. The intervention was estimated to reduce the weight of incinerated GMW with at least 40% with segregation of plastic products, and additional 16% by disposing of absorbent products in TONTO. Additional research is needed to determine the true recyclability potential of the plastics. With the foresight of the implementation of new products in the system and a circular model where materials of these products have to be kept in the loop, the endoscopy nurses will be equipped and trained to accomodate these changes, and maintain sustainable practices.

The aviation industry is responsible for 2.5% of global CO2 emissions, emitting over one billion tonnes of CO2 in 2018 (Ritchie, 2020). The International Air Transport Association (IATA) committed to net-zero aviation by 2050 (International Air Transport Association, 2022). The first steps toward net-zero aviation can be taken in the ground operations. Air France KLM set the goal for net-zero ground operations by 2030 (KLM Royal Dutch Airlines, n.d. -b). The aircraft hangars are responsible for 67% of all ground operations emissions at KLM (Veldhuizen, van, 2022) and a large portion of those emissions can be regarded to the heating of the hangars. The process of heating the hangar is neither efficient, nor effective, despite the large amount of energy it consumes. The opening of the hangar doors to pull aircraft in and out of the hangar cause the temperature inside the hangar to approach the outside temperature. It takes 4 to 6 hours for the hangar to be up to the desired temperature again, but oftentimes the hangar doors will have been opened before the desired temperature is reached. It was found that heat in the hangar is firstly needed for the mechanics working there and secondly for the aircraft when specific repairs with a curing element have to be performed. The fluctuations in temperature lead to thermal discomfort for the mechanics (Lampret et al., 2018) and negatively affect the drying times of sealants. This study discovered potential energy savings of 69% when the base temperature would be lowered to 10°C and heat would be provided locally where it is needed. The 69% in energy savings can be translated to money savings of €60.000,- per winter month (December 2021 taken as reference), or close to €400.000,- per year and 436 tons of CO2. Alongside the research into potential energy savings in the hangar, ideas were collected within the company. The ideas were visualized and feedback was gathered at different divisions within KLM. The ideas were divided into two main categories, namely Heat Conservation and Local Heating. In the course of the project it was chosen to focus on local heating. The heating analysis showed that conserving the heat in the hangar was not a feasible solution since the hangar doors are opened for too long for heat conservation to be effective. Furthermore, when the base temperature is lowered, and additional heating is done locally where needed, there is not a lot of heat to be preserved in the first place. The study proposes to lower the base temperature in the hangar to 10°C and provide local heating for the mechanics through heated apparel. The aircraft is heated locally during the curing phase of composite repairs but is often not heated with other curing processes such as after paintjobs. It should be considered to heat the aircraft locally more often to ensure optimal fleet availability.

THE BRIEF & HET TUSSENLAND The moment a patient receives the diagnosis of an incurable disease, it often feels like their whole world collapses. One patient explained this feeling as entering the in-between-land, the transition period from ending curative care and entering the end-of-life care. This in-between-land feels like entering an unknown land where you do not know the way and do not speak the language. Hospice Bardo expressed an interest in supporting these patients using the technology Virtual Reality. Therefore, this thesis aims to create a place for people where they can safely land in these tumultuous times and feel welcome to engage and open up to the 'in-between land' using Virtual Reality. RESEARCH & DESIGN GOAL During this thesis, research activities have been performed to get insight into the patient's wishes and needs. Literature research and explorative interviews were performed to get insight into the patient's journey after the diagnosis of an incurable disease. The interview panel consisted of patients, loved ones, care professionals, and experts in the palliative world. The insights of this research have been clustered and led to fourteen criteria that support the design goal. IDEATION & CO-CREATION The criteria were used as an inspiration for the ideation. Four students worked on this project in a hack-a-thon of Young Medical Delta and created a framework that complemented this research, leading to the final design. This framework exists out of five worlds that all answer to a different need: The forest, the library, the home, the communal space, and the beach. THE FINAL DESIGN | THE ENTRANCE TO HET TUSSENLAND The Tussenland is a digital platform that will be offered to the patient after the bad news. In this thesis, only the entrance to The Tussenland is designed. 'The Entrance to The Tussenland' is a forest-like environment in Virtual Reality where people are welcomed and shown around by a guide. The patients own a tree where their experiences grow as blossoms on their tree. The tree can be shared, enabling others to enter this world and comment on these experiences. EVALUATION For the final design, a prototype was evaluated by the panel. The panel was pleased with the meaningful interactions that were created in the design. It felt like a safe way to let people be welcomed and immersed in this new magical world. The participants felt like it was a tool that enabled them to express their thoughts, give them information and offer consolation in a meditative world. IMPLEMENTATION A service system map and roadmap were created for the future development of 'The Entrance to The Tussenland.' The three milestones in this roadmap are the pilot, launching 'The Entrance to The Tussenland', and further development of The Tussenland. DISCUSSION & LIMITATIONS However, the platform still needs to be developed as a full-service VR application. It is now a demonstration of what it could look/feel/sound like. 'The Entrance to The Tussenland' is not a concept meant for everyone because not every patient wants to engage the in-between-land. CONCLUSION In conclusion, the platform and service 'The Entrance to The Tussenland' supports patients after the bad news conversation by letting them safely land in the in-between-land.

As the oldest zoo of the Netherlands, Artis aims to provide her visitors with a carefree experience. Artis offers mobility support by means of freely available carts to ease the visit of young children and their caregivers. The identified shortage of children carts influences the visitor experience negatively. Increasing the number of carts is not considered an option because of the lack of space in the park and high costs per cart. Furthermore, the cart retains an iconic status within the park, which makes Artis hesitant to change. This research aimed to redefine the mobility support service for children and caregivers in Artis. The goal was to design a product-service combination that fulfils both the needs of the visitor, Artis staff and management. Wide-ranging research including interviews, observations and desk research brought together the views of the internal stakeholders and visitors. Synthesis of data points and insights showed that there is not only a shortage of carts and a lack of space, but that the current service does not meet the expectations of the visitor. The service was thought to be unpredictable, inaccessible and unavailable and the cart was considered unsafe, not suitable for all relevant ages, and had many physical shortcomings. Also, the service blueprint showed that the service challenges the organization by high demand for maintenance, unpredictable daily servicing and unwanted involvement of the front office. Concluding, both the service and cart needed to be redesigned to tackle the identified problems. Key challenges and design criteria were formulated to guide the design process; the service-product combination should provide suitable and safe mobility support for caregivers and children aged 1 up to and including 3 years of age which can be picked up, left and parked any time. A self-service is sought that is predictable and accessible. The service should provide sufficient capacity, require minimal (daily) maintenance, fit the park vision and should use minimal space in the park. An intensive design process followed and resulted in a product-service proposal. The proposed service provides readily available and predictable mobility support that fits children and their caregivers with different age-dependent needs. A large number of inviting and safe, one person pullcarts is offered which can be picked up and left at any of the ten compact stations throughout the park, thus stimulating intermittent use. It is a nonsupervised self-service using tokens. The cart is made of simply bent powder-coated steel tubes and weather-resistant wood, making the cart durable, relatively easy to produce and maintain. The carts nest in stations allowing for minimal use of space, they are unobtrusive and can be scaled up easily. The proposal was evaluated with visitors and main internal stakeholders. Visitors saw value in the possibility to take and leave a cart at the different stations and the availability of information made it accessible. Furthermore, the cart was considered safe. The Artis staff considered the concept valuable in the short term and long term and concluded that implementation of (parts of) the concept would improve the visitor experience. Review of the newly designed product-service concept leads to the conclusion that the proposal is an improvement on the current service. Time restrictions limited further development of the concept. Before the cart is production-ready, several parts need further development and testing with 1:1 scale prototypes. Meanwhile, elements of the proposed service can already be integrated to improve the current service. Interactions with new service touchpoints can then be validated in the park. When the new service is launched, practice must show if the stations are located in the right place and if the number of the proposed carts and stations suffices to stimulate the sharing of carts.

Dementia is a part of our society. One in five people, and for women even one in three, will develop dementia. Dementia has a significant impact on the lives of those affected, as well as their loved ones. This design project focuses on the impact of dementia on the adult children of a parent with Alzheimer's disease. Once a parent is diagnosed with dementia, a complex situation occurs that forces the adult child to adapt to - and cope with - this new situation. A situation in which three processes can be distinguished: dementia and its effects, the social connection(s) between them or others and the grieving processes. These three processes create a complex reality as each of them are unpredictable, unique to the individual, and influences and intertwines with the other processes. To understand and to design for this complex world; several research and design activities have been conducted to map this context that the child and parent with dementia are in. These activities aimed at involving the perspective and experience of both experience and dementia experts. Due to Alzheimer's, the brain cells of the parent are damaged, affecting their behavior, thinking, and emotions. There are three stages, in which the parent first mentally and later physically deteriorates. The dementia in the parent's brain brings many changes and losses, especially of great impact on the adult child in the long term. It is noteworthy that there are many formal caregivers involved in the care of the parent with dementia. The experience of support provided by these formal caregivers to the adult child depends on the individual characteristics and approach of the caregiver. There is a clear need from the perspective of formal care for tools and strategies to better understand and support the loved ones of the patient. Within the informal social circles of the adult child, differences in coping mechanisms can sometimes manifest themselves in not experiencing the desired support. Because grief is often associated with loss through death, anticipatory grief that accompanies dementia does not always receive the attention it deserves. Anticipatory grief for the adult child is unique to the individual, unpredictable, and ambiguous. Providing space for this form of grief is crucial because it can lead to a healthier and less intense grieving process after the parent's death. Talking to others, sharing experiences, acquiring knowledge, and having social support are all important factors in creating this space. The exploration of these three processes through various research activities has led to the discovery of a phenomenon: the "period of acknowledgement". This period is characterized by the realization of the adult child that dementia is a progressive disease that cannot be avoided. They also come to understand that it is the disease that is changing their parent, and not the parent themselves. Acquiring knowledge about dementia and grief, and reflecting on their personal experiences, is essential in developing this period of acknowledgement. The design goal for this project is based on this period of acknowledgement: “to enable the adult child whose parent is dealing with dementia to discover the impact of the dementia on themselves with the help of knowledge about dementia and grief, thereby increasing the awareness and creating more room to grieve over time.” Various ideas were generated in brainstorming sessions, translated into physical prototypes to be tested with adult children, and further developed in co-creation. These design activities resulted in the development of a tangible reflection tool called "grip", which aims to provide space for adult children to explore and share their personal experiences and emotions related to the impact of dementia on their lives. The grip tool facilitates conversations between the adult child and a conversation companion with tangible words to visually represent experiences, emotions, and losses related to dementia. It allows for the exploration of coping strategies and the development of new ways of coping, and it aims to provide social support and space for the adult child to share their grief. Overall, the grip tool aims to enable the adult child to better understand the impact of dementia on their lives and increase their awareness, creating more room to grieve over time. However, further research will be needed to test and improve the impact of grip. Design recommendations for improving the tool have been given, such as simplifying the design, improving usability, testing with people in the avoidance phase, testing the effect on the long term, and creating a more inclusive design. In addition, suggestions have been made for implementing grip in the future.

The primary purpose of this Integrated Product Design master thesis has two purposes. The first is to gain a deeper understanding of the needs of the elderly with dementia that causes undesired behaviour or Behavioral and Psychological Symptoms of Dementia, such as wandering during the night. The second purpose is to design CloudCuddle Senior: a lightweight and inflatable bed tent that keeps patients up to 120 kg in bed and creates a feeling of safety in various use cases such as home, caring home or the hospital. Data for this thesis were gathered by doing a literature study, making rapid prototypes and doing qualitative user tests. These methods generated knowledge for two sub-sections of the CloudCuddle Senior Design. The challenge of the Structural Design part was to come up with a bed tent concept that will be stiff enough to keep patients up to 120kg in bed while being lightweight to ensure mobility and consider nursing activities in and around the bed. The Experience Design of CloudCuddle Senior is about creating a safe and comfortable experience in bed that take the needs of people with dementia into account. The literature research results provide the support that patients with dementia need dynamic stimuli. However, research often focuses and compares mainly the type or the meaning of the stimuli such as Snoezelen, light therapy and music therapy while intensity through pace and amplitude often forgotten. More research into the intensity of therapeutic activities may conclude that designers of new interventions should focus on creating an intensity of dynamic stimuli that matches the patients need instead of focusing on the type of stimuli. A concept design is proposed based on the results of the Structural and Experience Design research. One of CloudCuddle’s bed tent’s significant characteristics is its inflatable structure. Although it was tried to design a more stiff design through solely inflatable elements, hard materials are required to meet the requirement of keeping 120kg patients in bed. The results on research from an Experience Design perspective implies that a bed tent that impairs vision on all sides except on one side offers a sense of safety while still being connected to the room in which the patients sleeps and a sense of control. The results of both the Structural and Experience Design research are combined in a final concept design for CloudCuddle Senior that should be prototyped and tested on strength and experience.

In this project a strategic model for sustainable community development through tourism is designed. A pilot research in Ljusnarsberg, a deteriorating rural community in Sweden, is performed to develop the strategic model to come to a final concept. The result is a final strategic model based on literature research, insights from the pilot research area’s context analysis and experiences of implementing the strategic model in the pilot community. The final concept of the strategic model presents a local organization that connects its community to the ecotourism market to change the economical, socio- cultural and environmental deterioration into sustainable development. The organization facilitates active tourism development and reactive community development towards a strongly sustainable paradigm. In this paradigm all development is done within planetary boundaries. Though still highly developmental, the strategic model could turn a deteriorating rural area into a developing community that is attractive to live and sustainable for the future. Next to that can the model make rural living a more viable option, combating not only rural deterioration, but also the negative effects of urbanization.

Executive Summery Plastic waste pollution is a well known global problem, also in Watamu, a little village on the coast of Kenya. The living conditions in Watamu are harsh, with a lot of unemployment and poverty. People depending on tourism which is negatively related to the plastic pollution on the beach and in the village. The housing situation for locals suffers from poverty as well, many locals lack proper shelter. The project described in this report helps to solve these issues in many ways: 1. Remanufacturing of plastic waste creates economic opportunities and reduces the waste in the environment 2. Making building blocks out of the plastic waste provides low cost building material 3. Low cost building material enables better housing opportunities for the locals The research was made possible by Steve Trott, owner of EcoWorld, a local plastic waste processing company. The company’s ambition is to grow and ignite the plastic waste circular economy in coast province Kenya. The next step in this ambition is remanufacturing plastic waste material into useful products. The deliverables of this project are: 1. A minimal viable production process of (re-)manufacturing building material from plastic waste 2. Identification of the impact on social-wellbeing, environment and economic opportunities (using the triple bottom line framework). 3. Implementation roadmap for EcoWorld Research process and outcome The following research activities are performed, described with the outcome: 1. An analysis to get a good and qualitative understanding of the local context and the (potential) impact of the design. 2. Data analysis to create a list of insights that are used as inspiration and requirements for the design process. 3. An inclusive decision making process concluded to focus on designing building bricks for school in Watamu. 4. Material selection based on availability of waste and producibility at EcoWorld, resulting in recycled PP waste as feedstock. 5. Literature study on plastic waste bricks to learn from existing research, resulting in melting and moulding the plastic waste into an interlocking brick shape. 6. Design cycles on production process and material composition of the bricks. The outcome was a series of 23 different bricks containing either HDPE, PET or PP in combination with sand or other additives. 7. Destructive testing on the 23 bricks to find the influence of the different plastic sorts, with a chosen best option as outcome; PP plastic. 8. Final test on compressive strength at the TUDelft to find the best recycled PP mixture composition considering strength and cost and to prove the feasibility of the selected brick (the minimal viable product). Description of the final design The minimal viable production process was co-designed locally, with local skill and materials. This process was used as an experimental set-up to test the shape, weight and size of the brick, the local opinions, the mixture composition and insights for the next phase of the brick production line development. The tests with different material compositions lead to the final choice of 50% recycled PP and 50% fine sand...

This master thesis was completed at the TU Delft in collaboration with Pezy Group for the company O4 Wheelchairs, with the goal of optimising the production and assembly of their wheelchairs, by standardising the wheelchair design.  In the field of fully customisable wheelchairs (ultra-personalised products), the conflicting interest of the need for customisability and standardisation to optimise production is prevalent. By standardisation of the wheelchair assembly, without compromising the needed customisability, the production time of O4 wheelchairs can be improved benefiting both the company and its stakeholders. To achieve the goal of a shorter production time, the production at O4 Wheelchairs was analysed, and multiple opportunities were formulated. These opportunities were further elaborated by turning them into design questions, and their potential was assessed with brainstorming sessions and low-fidelity prototyping. From these opportunities, one direction for a concept was chosen to be fully developed in this project. In contrast, the others were formulated into a roadmap of specific steps for O4 to take to improve their production. The chosen concept was further developed by prototyping and testing, ranging from cardboard and 3D printed models to fully laser-cut aluminium parts. This led to a design proposal for a new fender assembly. This new fender assembly integrates the brake into the assembly and ensures exact fixation without the need for measuring. It is usable in all wheelchair configurations and with the three sold wheel sizes.Testing the new fender assembly with assembly workers at O4 Wheelchairs resulted in an estimated time of 16 minutes, compared to the 37 minutes it takes to assemble the old fender assembly. The improvement of 44% in time, a cost decrease of roughly €30 and the design being less error-sensitive due to the straightforward way of fixation, all add to the value brought to O4, with the design proposal.This project provides multiple starting points for O4 Wheelchairs to further improve their production and product line. The design proposal also promises a substantial improvement to their current fender assembly. 

Over recent decades, the quality of death and dying has received much attention in society. Many patients with terminal cancers or admitted to intensive care/acute units are in need of care for the end of their life (Susan, 2015). With this need rising up, palliative care service is gradually developed mainly as the setting of hospice or home care. However, some patients who are terminally ill are in a situation in need of hospital medical settings to manage their symptoms (Cotogni, 2018). Therefore, in-hospital palliative terminal care becomes important for those patients/families in terms of guaranteeing the quality of life in their last days or hours. Currently, most western hospitals, including Maasstad Hospital, implement palliative terminal care with the integrative model (Metaxa, 2019) which needs general medical professionals, especially nurses, to provide palliative care as a part of routine practice combined with a consultative palliative care team, which is a reported as a challenging work for nurses (Bratianu, 2015) (Johansson, 2011). The project aims to investigate how to support nurses in the Oncology Department of Maasstad Hospital to be able to provide palliative care to patients. Through a series of literature research and interviews from historical (trend), cultural, user and context, and technology aspects to understand and explore the context, the design opportunity, supporting junior nurses with palliative care on-site learning, is unearthed. Insights gained from supplementary research helps the project further define the design goal: to create virtual training of palliative care for inexperienced nurses on emotional and spiritual capabilities, where nurses gradually become mentally prepared to provide palliative terminal care for dying patients and families, to ensure nurses’ mental well-being while being able to provide emotional and spiritual care to patients and families with quality. A VR demo is built for nurses to evaluate the concept. Due to the Covid-19 situation with limited access to nurses, the evaluation result is not quantitative which means further user tests and evaluation need to be considered. The final design is perceived by the nurse as to be promising to provide the inexperienced nurses or even other medical professionals with a safe environment to learn to cope with their own feelings, explore and make mistakes, and be eventually more comfortable and confident to look after dying patients and their family members. However, since the design mainly focuses on the training program structure and the experience journey, more opportunities and details of the interaction design still need to be developed and tested if the application is expected to be launched. The recommendations regarding these details and opportunities are provided as the end of this project.

Ice skating is (still) very popular in the Netherlands, and it is gaining popularity across the globe. Temporary ice rinks on squares and in parks is an increasing solution in order to attract visitors in the winter and holiday season. Ice-World International, the world leader in temporary ice rinks since 1992, has experienced a significant increase in demand for temporary ice rink rental in the Netherlands. As a premium supplier, Ice-World wants to keep offering its customers high quality and innovative solutions. Therefore, Ice-World asked to explore opportunities for updating the boarding systems with a new modular boarding system that fits every rink dimension and could replace current systems. This graduation project has resulted in a redesign of the wooden boarding system. A boarding system is used as a barrier around an ice rink to prevent ice skaters from sliding or falling off the ice. It is a modular system, as every ice rink has different dimensions. Currently, Ice- World carries two different types of boarding systems: a transparent boarding and a wooden boarding. The wooden boarding is preferred by European customers, while international customers prefer transparent boarding. Existing problems with the boarding especially relate to the wooden system. The focus of this project was set to the wooden boarding because of increasing market demand (within the Benelux), and it is the core business of Ice-World.

This research examines the potential for sustainable packaging in the context of supermarket products, focusing on the concepts of reuse and standardisation. The central question addressed is whether consumers retain positive attitudes towards purchase intention, brand image, perceived quality, aesthetic attractiveness, and perceived environmental friendliness when packaging for fast-moving consumer goods (FMCGs) is standardised to its core function of protection, while marketing elements are transferred to online communication channels. The study uses a wide range of methods, including reading lots of articles, talking to people who know a lot about the topic, analysing data, experiments and in-depth interviews. The findings reveal positive consumer responses towards the concepts of reuse and standardisation. Although no statistically significant results emerge from the mixed experiment design, the analysis of open-ended questions demonstrates a clear and positive attitude among participants. Consequently, it can be concluded that consumers generally show a favourable and cooperative attitude towards packaging standardisation and reuse, provided that convenience, hygiene and accessibility are prioritised. This research is of significant relevance due to the substantial volume of plastic waste generated by packaging, evolving legislative frameworks, and the urgent need for environmental changes. It emphasises the necessity for proactive changes and innovative approaches to address sustainability challenges in the packaging industry. By shedding light on consumer perceptions and preferences, this study offers valuable insights for businesses and policymakers seeking to navigate the transition towards more sustainable packaging practices.

Textiles are unimaginable out of our lives - from the moment a human is born until existence stops - textiles are touched by wearing, seeing and feeling them. Where it once was fundamental for survival, today, the textile industry has grown towards a system that prioritises speed, efficiency and uniformity (Goldsworthy & Politowicz, 2018) while largely neglecting the impact of waste, mass production and material extraction. The industry designed a system that prioritises the desires of form, function, aesthetics and cost above the environment. A design process with a systemic lens acknowledges waste as an essential element in the system, enabling an execution providing for a circular economy. The exploration consists of technological, experiential and aesthetical research of woollen Woven Textile-form in which the shape-changing properties of wool fibres make them morphic Textile-forms. The potential for a circular economy, using biodegradable, recyclable, mono-material widens the scope towards multimorphic Textile-form (McQuillan & Karana, 2022). This research aimed to unfold techno-aesthetics emerging from material expressions through woollen woven Textile-form exploration in a circular economy. Experiential Characterisation (Camere & Karana, 2018) unfolds the material experiences of the created samples, identifying a new aesthetic formed by materiality. Techno-aesthetics (Dalmasso, 2019) questions the origin and nature of aesthetical values concerning technology, demonstrating the necessary value change of perception and expectations of the typical textiles and textile-based products and potentially beyond when a sustainable design outcome is a goal. All together, this should make us seriously question the appropriate perception and expectations of typical textiles and textile-based products and potentially beyond when a sustainable design outcome is a goal. Woollen Woven Textile-form and Morphic Textile-Form methods, together, may create a new understanding of materiality to move towards Multimorphic Textile-form. This research suggests embracing material traces induced by exploring methods such as Woollen Woven Textile-form methods to unfold ‘new circular techno–aesthetics’ to create an understanding of materiality and move towards a circular economy. Embracing ‘circular techno-aesthetics’ through materiality may bring about the needed global fundamental change of value and move towards a circular economy.

This IPD (Integrated Product Design) master thesis describes the development of the LooWee. The LooWee was developed in collaboration an electric wheelchair user in search for a new toileting solution for female wheelchair users. The goal of this thesis was the further research the idea and design a new toileting solution that could replace the available tools. Currently, adult diapers or a catheter are the only options, but these are medically unnecessary. The two main issues with these tools are discomfort and capacity. They are either painful or won’t last the whole day. Limiting the user’s mobility and having a negative effect on their quality of life. Based on previous prototypes and the client experience, this thesis focussed on finding the most suitable design direction. Incorporating a tool into the wheelchair seat would fit most in the given context. However, it came with multiple challenges. The client sits on an orthosis and making alterations can influence the performance of the seat. Which was a problem that occurred in the previous prototype. Therefore the chosen concept focused on incorporating a urination tool without making large changes to the orthosis. Figure 1 shows only one small change is made to the bottom layer of the seat. Which is the ergonomic shape of the seat, which determines its performance. The embodiment of the chosen concept focussed on comfort and functionality. The different aspects of the concept were further researched. Prototyping and material testing were used to detail the design. In the end, all the results were gathered into the final design, as it is shown in Figure 1. The LooWee can be added to a Lewis orthosis. This seat has a tilted orientation, which is used by the LooWee to drain the urine to the back of the seat. A silicone product is sunken into the seat, to keep it leveled with the top of the seat. A curved shape sticks out from the seat surface with the opening. This curve will form to the user’s body and capture the urine directly at the source. Urination through the opening will help control the unpredictable female urine stream and prevent spilling. A toplayer will cover the silicone part, for comfort (mask the feeling of sitting on an opening) and to prevent sweat. The drained urine is stored at the back of the wheel, provides enough room to store the urine of a whole day. The embodied design was validated with a comfort and functionality test.

Virtual Reality glasses are being used in hospitals in order to combat pain and anxiety. These glasses are consumer products however. This project aims to find a feasible solution by designing a custom product that replaces the problems diagnosed in the current product and that enhances the user experience.

During design projects, designers create and gain a lot of important knowledge that explains how and why certain steps are taken in the process of designing something new. Methods, best practices, pitfalls, and other important insights that might be useful for future projects are often lost in transition due to a lack of structural knowledge sharing. This report describes a research into this problem, and results in a design that improves the process of knowledge sharing.

The Flying-V in itself is an excellent project to view in which an extraordinary collaboration between different faculties of Delft University of Technology and companies work closely together. This project’s beauty is that through innovations, we can start a new way of flying with a white canvas. This project focuses on how passengers, cabin crew and other stakeholders deal with the significant hand luggage problem. Because of the many possibilities due to the Flying-V’s new design and because there is nothing fixed within the interior, there are enough possibilities to solve this problem and increase the Flying-V’s experience. This report consists of different phases, from research to a final integrated product. During the process, research was carried out into how hand luggage is currently handled. Researching the market trends and opportunities to improve this part of the journey. This will lead to creative sessions with stakeholders, experts, and interested parties to gain insight into the aviation industry’s world. The research phase led to an ideation phase with a lot of ideas to final concept directions. All this weighed up to the best possible solution was decisive for one concept. After testing and further development, this has led to a final product where ‘fast and comfortable hand luggage stowage unites’.
