Designing a nature-inspired, user-centred, passive thermal system

Master thesis (2026) - I.A. de Bree, S.M. Persaud, C.P.J.M. Kroon, Oep Schilling
Long before refrigeration existed, people used the earth to store their food and keep it cool. The Groundfridge revives this principle: a prefabricated underground root cellar designed for off-grid living and passive food storage. It relies on the stable temperature of the surrounding soil to passively cool its contents, but exposure to atmospheric conditions causes internal temperatures to fluctuate during warmer periods.

This graduation project explores how the Groundfridge can become an integrated system by reconnecting the product, its user, and nature. It investigates how conductive, convective, and radiative heat transfer can be optimised through redesign, while embedding user needs and sustainability. Rather than treating cooling as a purely technical challenge, the design seeks to make environmental processes visible, understandable, and meaningful to the user.

The Living Groundfridge represents two interventions: the Climate Gate, which increases thermal resistance, and the Groundflow system, which leverages evapotranspiration through a self-regulating water supply and vegetation plan to actively cool the Groundfridge hill. Together, they demonstrate that designing with nature, rather than against it, can create solutions that are thermally effective, ecologically beneficial, and meaningful in daily use. ...

A transition pathway for circularity in healthcare practice

Master thesis (2026) - E.R.E.M. van Hees, J.C. Diehl, C.P.J.M. Kroon
Healthcare delivers major health benefits but also generates significant waste and emissions. In interventional cardiology, many products are used once and then incinerated as hazardous waste. This report focuses on the TAVI procedure as a representative example: a procedure in which high-value, single-use products containing high-quality polymers and precious metals are used. This results in a loss of material value and repeated demand for virgin resources.

The central problem addressed in this project is that improving end-of-life outcomes is not only a product challenge. Even if a device is technically recyclable, it can still be incinerated if the workflow, waste routing, contracts, and responsibilities remain unchanged. Circularity, therefore, requires system change.

This project aims to identify ways to improve the end-of-life of the TAVI products to reduce environmental impact and value loss while maintaining clinical safety and compatibility with the Cath lab. The work addresses this through a combined product-and-system approach. System-level analyses were done to understand how the end-of-life is shaped in practice.

Product-level analyses were done to identify environmental and material hotspots. These findings were translated into design requirements to identify realistic directions for intervention.
 
Based on these findings, a transition strategy is proposed. The near-term focus is on a recycling route that is compatible with the current system. This phase aims to reduce incineration and enable higher-quality material recovery through design-for-recycling and material transparency. The longer-term direction is partial reuse of the delivery system's handle, which offers higher value retention but requires additional conditions, such as validated sterilisation and inspection, traceability of use cycles, and a defined liability and quality contract. Co-creation sessions were used to test feasibility assumptions and to clarify what stakeholders need to implement such changes in practice.

The report concludes that a circular pathway for the TAVI delivery system is feasible only if product interventions and system interventions are developed together. The deliverable of this project is a booklet to help all stakeholders realise this transition. ...

Designing for Meaningful Interactions and Longevity in Kitchen Appliances

Master thesis (2026) - B.A.M. Koppert, M.C. Dekker, C.P.J.M. Kroon, Markus Orthey
The amount of products we own combined with the ease of obsolescence, result in a huge environmental impact. Our attitude towards products is unsustainable and designers have a responsibility to guide consumers toward more meaningful and lasting relationships with the products we buy.

Since the kitchen appliance market is highly saturated, focus on functionality and affordability makes it hard to compete. There is an opportunity in adding other types of value (emotional, social, epistemic and conditional) to Braun kitchen appliances, to be front runner for the transition in kitchen context and product ownership.

The choice to cook often results in a trade-off between time, cost, and health. The mega-trends show that health, sustainability, self expression and community become increasingly important. Therefore cooking will transition from a functional activity to an experience-based one. The purpose of cooking will be to acquire skills or to connect with oneself and others.

The conceptual design, 'The Turning Point', transforms the cooking process into a satisfying and enjoyable experience. Users can choose between hand-pulling and foot-pumping movements, which are converted by a visible mechanism into a rotational driver for kitchen appliances. This replaces all electric rotating motors in the kitchen. The interaction between user and product requires effort from the user, thereby strengthening their relationship. Direct feedback makes people feel in control, and they value the end result more when they have put in the effort themselves.

The future persona will put time and effort in their kitchen appliance and associates the product with a positive experience. The investment and positive association lead to more product attachment. Care and maintenance feel natural and satisfy the user. Their daily movements contribute to a healthy lifestyle.

The report is structured based on the Vision in Product Design method (ViP). The current context is compared to the future context of 2040, which is used to create a design vision. The Turning Point is a showcase that embodies communicates this vision.

A design study on making pumptrack modules from discarded wind turbine blades

Master thesis (2025) - J.K.R. Pupping, C.P.J.M. Kroon, J.J. Joustra
The rapid expansion of wind energy over the last 40 years is leading to an increasing number of discarded wind turbine blades as they reach their end of their life. Current solutions are low- grade recycling options in which the material loses its value. With that.

This research presents a case study on the structural reuse of wind turbine blades, using an iterative design research approach to explore processes and outcomes.

Previous research has investigated various reuse cases but has been unable to develop a proof of concept for the reuse of curved material. In this case study, the research explores the potential of utilizing the blade material’s unique geometric and material properties by developing a demonstrator prototype to show its feasibility.

This case study researches the process of matching wind turbine blade (WTB) pieces to create a modular pumptrack. This will be done by calculating the material’s strength and finding ways to connect the modules, ensuring form continuity and sufficient tolerances.
In addition, the project ends with the conceptualisation of prototypes and the validation of the geometric and material properties to ensure their suitability for modular pumptrack modules. These modules are designed to be safe for BMX pumptrack events while considering their limitations and opportunities.

To showcase the experiential qualities of the material—such as its aesthetic attributes and associations—to both the industry and the public, the prototypes were presented through a demo pumptrack event hosted within the Delft University of Technology (TU Delft) community.

The final section summarizes the outcomes and riding experience of the pumptrack modules, providing insights into reusing wind turbine blade material specific for this use case and other cases.

This graduation project, Connecting the Rijksmuseum with Older Adults in Transition from Work to Retirement, explores how the museum can foster lasting engagement with people approaching retirement by supporting reflection, purpose, and connection through art. Conducted within the MSc Design for Interaction at TU Delft and in collaboration with the Rijksmuseum in Amsterdam, the project follows a human-centred and context-driven design process.

The research unfolds across five phases. In the Discover phase, the context of ageing, purpose, and retirement was examined through literature, a survey, and interviews with future retirees and professionals who use art in guidance and transformation. Findings showed that while many older adults look toward retirement with curiosity and optimism, they often struggle to translate their professional identity into a renewed sense of purpose and structure. The emotional dimension of this transition is rarely addressed, leaving a gap between the formal end of work and the beginning of a self-defined new phase. Farewell rituals typically mark retirement as a single event rather than a gradual transition, offering closure but little space for reflection or reorientation.

In the Define phase, insights were synthesised into the design challenge: How might the Rijksmuseum support future retirees in meaningfully reflecting on their working life and rediscovering purpose through art? A corresponding design vision positioned art as a tool for reflection and emotional connection, bridging the personal and cultural dimensions of this life transition.

During the Design and Develop phases, an initial conceptual idea—the Retirement Experience—was shaped into the refined concept Uit de Verf. The concept unfolds through four sequential experiences: (1) receiving a tangible farewell gift from the employer, (2) engaging in digital, art-based reflections that guide the retiree to explore personal themes and values, (3) co-creating a personalised symbolic artwork that becomes a meaningful memento at the farewell moment, and (4) establishing an ongoing connection with the Rijksmuseum and a community of other retirees. Together, these steps turn a traditional farewell gesture into a reflective transition experience that blends personal meaning, artistic expression, and social belonging.

In the Deliver phase, research into implementation with employers, market potential, and the museum’s role was conducted. A user test with future retirees evaluated the emotional, reflective, and practical value of the concept. Results showed that Uit de Verf met the needs of all three main stakeholders: retirees experienced recognition and inspiration for their next life phase, employers found a meaningful way to honour employees, and the Rijksmuseum gained a new pathway to engage a currently underrepresented audience segment.

The project concludes that design can support social transitions by connecting cultural meaning with personal transformation. Uit de Verf strengthens the Rijksmuseum’s relationship with older adults by using art and reflection to guide the journey from work to retirement, helping individuals enter a new phase with awareness and purpose. ...
Master thesis (2025) - M.I. Nods, C.P.J.M. Kroon, S.C. Santema
This graduation project investigates KLM’s Unaccompanied Minor (UM) service, with the objective of enhancing its effectiveness and alignment with KLM's branding and operational goals. Using the Double Diamond design methodology, the project is structured into four key phases: Discover, Define, Develop, and Deliver.

Discover

Research uncovered key challenges within the current UM service. These include inefficiencies in communication, operational bottlenecks, and user discomfort with existing tools, such as the UM necklace wallet. Insights were gathered from interviews with caregivers and minors, on-site observations at Schiphol Airport, and analysis of customer feedback. Emotion maps and a stakeholder map provided a clear visualization of the pain points and interactions throughout the UM journey.

Define

Insights from the Discover phase were synthesized into actionable goals to address the identified challenges. These goals included creating a seamless, reassuring experience for minors, improving caregiver communication, and ensuring alignment with KLM’s brand values. The UM service journey was mapped to highlight specific areas for improvement, laying the foundation for targeted redesigns.

Develop

Solutions were developed to address these challenges, including a redesigned UM necklace wallet featuring eco-friendly materials and improved visibility of flight details. Enhancements to the Junior Jet Lounge were proposed to create a more engaging and child-friendly environment. Additionally, digital tools were designed to streamline caregiver communication and offer real-time tracking of the minor’s journey. Visual prototypes and customer journey diagrams were created to illustrate these proposed changes.

Deliver

The proposed solutions were tested with users to validate their effectiveness. The redesigned UM necklace wallet and updated lounge facilities received positive feedback, improving both usability and customer satisfaction. A Future Roadmap was developed to guide the phased implementation of these solutions:
•Short-Term Goals (0–6 months): Launch of the enhanced website, rollout of a redesigned UM wallet, and implementation of an updated AFS UM desk design.
•Medium-Term Goals (6–18 months): Expansion of the Junior Jet Lounge and a unified check-in desk.
•Long-Term Goals (18–36 months): Standardization of UM processes globally and development of an all-digital UM journey.
This roadmap ensures that improvements are implemented strategically, with room for continuous evaluation and refinement based on feedback.

Results and Impact

By addressing the identified challenges and implementing the proposed solutions, this project positions KLM’s UM service as a best-in-class offering. The focus on safety, clarity, and user-friendliness aligns with KLM’s brand values of care and reliability, fostering trust and loyalty among both minors and caregivers. The phased approach outlined in the roadmap supports sustainable growth and ensures that the service remains adaptable to future needs. ...

Optimising the assembly by standardisation for fully customisable wheelchairs

Master thesis (2024) - K.E. Ruijgrok, D.J. van Eijk, C.P.J.M. Kroon
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.

A human-centered design approach to waste segregation in colonoscopy procedures

Master thesis (2024) - M.S. Clercx Lao, J.C. Diehl, C.P.J.M. Kroon, P.J.F. De Jonge
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.

Master thesis (2024) - M.L. van den Boogaart, J. Martins, C.P.J.M. Kroon, Daan Houtzager, Leon Haines
Reefs are the most important marine ecosystems that support the majority of marine life in our oceans for both temporary and permanent shelter, refuge and food supply. However, reef ecosystems around the world are disappearing and artificial reef structures are an opportunity to help restore them.

This project contributed to the field of artificial reefs, by designing a surface pattern on both millimeter and centimeter scale, that aims to enhance and support biodiversity on the large concrete “ReefBlocks”, by the company Reefy. That serve as both artificial reefs and as functional infrastructure, such as breakwaters and dams.

In an extensive literature research, information on marine environments was collected and three main types of inhabitants that can be found in reef communities were identified, including only those that interact with hard substrates like the ReefBlock. The three different inhabitant types were distinguished based on their unique role within ecosystems, which they need to grow, stay balanced and provide the necessary ecosystem functions.

To understand the ecological requirements for the pattern design, existing knowledge on increasing biodiversity with artificial reef substrates was researched and summarized in a micro marine spatial plan on the scale of an entire ReefBlock. The addition of crevices and pits of varying sizes on centimeter-scale and grooves on millimeter-scale were concluded as the main crucial design features that need to be reflected by the final pattern design.

A design vision to aim for biomimicry of lobed brain corals was formulated for the aesthetics of the proposed pattern design. As brain coral patterns have a visually organic complexity and flexibility that allows for the natural implementation of the identified crucial design features. In order to achieve the pattern design vision that meets all the collected ecological, stakeholder and production requirements, a design toolset was developed that combines the power of generative art with the power of parametric design.

The generative art tool allows the semi-automatic creation of lobed brain coral patterns in a similar process to how actual brain corals, and many other examples in nature, receive their pattern from, in a so-called reaction-diffusion system.

With the generative art tool, a black and white 2D image is generated, which is then used as the input variable for the parametric tool. Which directly translates the 2D image into a perfect 3D surface pattern. This method ensures that the pattern design always meets the various production requirements.

In order to support the choice for the aesthetically best-rated design by the general public, a survey with 60 respondents was conducted with questions based on the stakeholder requirements.

In order to validate the effectiveness of the pattern design within the timeframe of this project, a six weeks lab test was conducted using concrete prototypes of the pattern design and microalgae. The test showed promising results for meeting the defined ecological requirements.

Lastly, a rubber form liner was produced in order to help Reefy along with future field tests with the proposed pattern design, in order to validate the conclusions and insights gained in this graduation project, and in real marine environments, for a much longer period of time.
The design toolset was initially created to support the iterative design process and helped to quickly try, test and compare a multitude of designs. But in the end, this toolset has proven to be very valuable for future use by Reefy as they plan on extending their product line with smaller-scale wall panels and for potential adjustments to the proposed pattern design based on their field tests. ...
Master thesis (2024) - N. Cornet, M.H. Sonneveld, C.P.J.M. Kroon
In today’s fast-paced and increasingly individualistic world, feelings of loneliness and social isolation are becoming more prevalent. For students, navigating group projects can be challenging, not just academically, but also emotionally. Working closely with peers can bring about pressures to maintain a professional front, leaving little room for open conversations about personal struggles or support needs.

Recognizing the growing issues of loneliness and social disconnection in academic environments, the Support Board was developed to foster reflection, open communication, and mutual support within student teams. This project, focused on the Industrial Design Engineering (IDE) faculty at TU Delft, aims to create safe spaces within teams where students can reflect on their support needs, communicate those needs, and offer support to one another. By encouraging dialogue around support-seeking and support-giving behaviors, the Support Board seeks to improve team cohesion and promote a more empathetic and supportive culture within teams, ultimately enhancing both individual mental well-being and team dynamics. This lead to the following design goal:

Increase mental health of IDE students by developing a tool which helps create a supportive (team) environment and, in that way seeks to improve team cohesion

Through an iterative Research through Design approach, the project went through multiple phases of development, testing, and refinement. Initial research highlighted the need for interventions that encourage students to reflect on and articulate their support needs in a structured yet accessible manner. The Support Board addresses these needs by incorporating recognizable archetypes, support tokens, and guided reflection exercises to help team members understand their roles in offering and seeking support.

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. ...

The implementation of “The Entrance to the Tussenland”. Supporting people with an incurable disease in their journey to the in-between-land

Master thesis (2022) - Z. Zheng, M.H. Sonneveld, C.P.J.M. Kroon, C. Rhodius
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.

Master thesis (2022) - B.L.T. Arts, H.L. McQuillan, C.P.J.M. Kroon
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.

After testing and further development, this has led to a final product where ‘fast and comfortable hand luggage stowage unites’. ...

Modular Roof-System for Sustainable Household Provision

Master thesis (2020) - Linde de Jonge, J.J. Faludi, C.P.J.M. Kroon
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. ...

A tool to make the communication between patients and specialists more emphatic in the digital world of 2030

Master thesis (2019) - Hanneke van der Velden, Richard Goossens, Caroline Kroon, Stephanie Klein Nagelvoort-Schuit
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. ...

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. ...

The design of a bed tent for wandering people with dementia

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. ...
