To make electronic products fit for circular economy strategies such as life extension, refurbishment, and recycling, ease of disassembly is a key design quality. Several tools are available to assess the ease of disassembly of products during the design process, such as the ease ...
Is coaching student design teams a secret? Not really. But it is complicated and the best way to learn it is to dive in and be open. Experienced coaches put this cheerfully illustrated book together to help you recognise many coaching situations and the way to respond to them. Th ...

The Total Cost of Ownership Score

Unifying Repair with Durability and Improving Objectivity, Completeness, and Scalability

This paper introduces the Total Cost of Ownership Score (TCOS) as a comprehensive framework for evaluating and improving product repair, durability, and maintenance all together on a uniform scale. The scoring procedure, implemented through a spreadsheet, calculates a product's t ...
In September 2021, the faculty of Industrial Design Engineering (IDE) introduced a revamped bachelor's programme that emphasizes design for higher complexity, teacher as a coach, and autonomous learning. The programme includes Understanding Product Engineering (UPE), which teac ...

3D Printing for Repair

An Approach for Enhancing Repair

The availability and storage of spare parts are the main barriers to product repair. One possibility would be to 3D print spare parts, which would also enable the repair of products not intended to be repaired. Besides manufacturers, 3D printing spare parts is an interesting opti ...
Spare parts availability is crucial for extending the life of consumer products. However, long-term availability could lead to high stocks of spare parts, which might not be used. Instead, on-demand manufacturing of spare parts with additive manufacturing (AM) is a promising alte ...

Demonteerbaarheid

Essentieel om te kunnen repareren

In September 2021 the faculty of Industrial Design Engineering has implemented a completely revised bachelor. Important differences between the old and the new bachelor are its focus on design for higher complexity, the teacher as a coach, and the need for students to learn in an ...
In our Integrated Product Design master at the Delft faculty of Industrial Design Engineering we see a growing diversity in our student population. Besides a growing number of different nationalities there are also significant differences in prior education, competences, and soci ...

Opportunities For 3D-printable Spare Parts

Estimations From Historical Data

The Sharepair project aims to decrease the waste of electronic and electric consumer products and increase their useful life, by supporting repair communities and scaling up citizen repairs through digital tools. One of the focus areas of this project is to support the discovery ...
This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is a ...

The Circularity Calculator

A tool for circular product development with Circularity and potential value capture indicators

Most products require a redesign to be viable in a circular economy. For instance, by implementing design for disassembly, remanufacturing, recyclability, and using long-lived components. Typically, different solutions can be chosen to improve a products' circularity, and differe ...
Composite materials offer many advantages during the use phase, but recovery at the end of a lifecycle remains a challenge. Structural reuse, where an end of life product is segmented into construction elements, may be a promising alternative. However, composites are often used i ...

The Disassembly Map

A new method to enhance design for product repairability

Designers and engineers need better tools and methods to create highly repairable products. Design for disassembly and reassembly is an important product related design feature that can enhance repair. In a highly repairable product, the components that fail most often should be ...

Structural reuse of high end composite products

A design case study on wind turbine blades

Composite materials, in particular fibre reinforced polymers, present a challenge when reaching their end of life. Current recycling processes are unable to capture the high-end material quality, thus challenging (re)use of composite materials in a Circular Economy. Structurally ...
In the IPD Master’s in Industrial Design Engineering (TU Delft) we see a growing diversity of students. We see the international student population growing, but also see significant differences in prior education, socio-emotional aspects, and competences. Within the Advanced Embo ...

Dialogue for design teams

A case study of generative conversations for dealing with diversity

In the Integrated Product Design master’s at Industrial Design Engineering, there is a growing diversity in students. In recent years we increasingly noticed that diversity could lead to complications within the various student teams. Examples are miscommunication, frustration, a ...

Circular design of composite products

A framework based on insights from literature and industry

Composite materials are an attractive material choice as they enable lightweight, low-maintenance products with a long lifespan. Recycling these materials, however, remains a chal-lenge. Homogeneous material composition and the use of thermoset matrices complicate repro-cessing, ...

Circular Design of Composite Products

A Preliminary Framework Based on Insights from Literature and Industry

Composite materials are an attractive material choice as they enable lightweight, low maintenance products with a long lifespan. But closing the loop for these materials in a Circular Economy (CE) is challenging, especially for thermoset composites. In a CE, products should be de ...

Hotspot Mapping for product disassembly

A circular product assessment method

Designing products for the Circular Economy requires closing and slowing of loops by means of repair, reman-ufacturing, refurbishment, parts reuse and/or recycling. Ease of product disassembly facilitates these processes to be more cost-effective, resulting in a better circular s ...
