Circular economy - Sustainable design Design for the future Embodiment Formgiving Drawing Prototyping

About me Hi, I’m Stef de Groot. As industrial designer, I like to work on innovative products that make a valuable difference in users everyday life.

I am currently doing the master Integrated Product Design at the TU Delft. In my spare time I like to work on other projects and expand my knowledge in the field of sustainability and designing for the future.

During the design process, I like to work iteratively, through the use of sketching, CAD modeling, lo-fi prototyping in early stages and hi-fi prototyping to communicate the design in the later stages.

The Bike Project Home 3D-printing is growing at a rapid pace. In the future, high-quality mechanical parts can be produced at home. This introduces opportunities to build useful products, fully customised to the users liking.

The Bike Project is a “research through design” project to push the limits of consumer 3D-printing and to inspire others to contribute to an open bicycle design.

Research through design

Okt ‘14 - Apr ‘16 Featured in the Design Museum Gent

An open source bicycle standard, using aluminium profiles can motivate a database of bicycle designs and addons.

Total freedom in customisation means the user will be cycling a perfectly fitting bicycle, that fits its riding style, with the desired aesthetics and functionalities.

Our design includes the base model, visualised in orange. It proves how far the current technology is and how close it is to producing bicycles at home.

Countless test prints were needed to find the tolerances in the different print directions.

The 30x30mm aluminium T-slot profiles are fixable to the printed parts by nuts and bolts.

We are currently working on a parametric model that changes frame size depening on given body measurements.

The second version of the bicycle got exhibited at the Design Museum Gent, the Brussels Embassy and the RapidPro industry fair.

SmartWindow In an era of reform to sustainable sources of energy, innovative solutions should be found. Solar panels use the top surfaces of buildings. The larger side surface of buildings, mostly made out of glass, creates a great potential.

For the YesDelft start-up Physee, we designed the next energy generating window for their roadmap.

Advanced Embodiment design Feb ‘17 - July ‘17 For the startup Physee

The user can change the tint of the window by interacting with the SmartHub or by using the Physee application.

Energy generated by the window is stored in the SmartHub.

The SmartHub automatically and manually changes the tint of the window.

Solar panel performance data is shared via the internet and obtained via the application.

Awaiting the efficiency improvement of the energy generating window, it is more feasible to store the energy near the source. The energy can be used by office employees to charge devices.

Furthermore, the inside environment is improved by dynamic shading the window. It optimises visual comfort and temperature in the inside environment.

The SmartWindow is a standalone solution because of the SmartHub. This avoids wiring costs in both energy generating- as dynamic shading windows.

The final shape is an evolution based on ideation and concept testing of aesthetics and interaction.

The convex shape visually breaks loose from the rectangular window frames.

The shape is inspired by other products that define our vision on energycontaining products.

CodeQube The Code Qube is an educational product which teaches school children to build their own html/css website.

We designed the second version of the CodeQube, which can be sent by package and assembled by children.

Concept design Juli ‘17 For the startup CodeQube

The new CodeQube is small enough to send in a package. The product is now cheaper to obtain by schools.

An elastic band pulls the sides together, while the top lid keeps it in shape. The result is a stiff construction with minimal use of materials.

The Arc Bicycle Since most 3D-printing is done by machines that work inside of the box, you are limited in print volume. MX3d developed a robotic printing method called “wire and arc additive manufacturing”. They asked us (a multidisciplinary team from the TU Delft) to develop a concept design showing the possibilities of the technology.

Minor Advanced Prototyping Dec ‘15 - Feb ‘16 Purmundus Challenge 3rd place

My main responsibility was designing the solid shape of the bicycle, with a focus on the mechanics, printing tolerances and aesthetics.

A grasshopper generated spline network is projected over the solid shape.

The end result is a fully functioning stainless steel concept bicycle.

We tested the bicycle by driving through the bumpy city center of Delft.

The story of “The Arc Bicycle� was covered on a variety of online media.

The Within Lamp Inspired by traditional manufacturing techniques, “The Within Lamp” was designed. The desk lamp is designed with a focus on minimalism and simplicity.

Advanced Prototyping Sept ‘15 - Nov ‘15 Design and one-off realisation

The neg and legs are made by laminating veneer with an MDF negative.

The wire is integrated into the neck during laminating. The shade is made of hand-turned aluminium.

Miura Packaging For decades, there has been no innovation making paint packaging easier to use. The process of painting is still inconvenient and messy.

For AkzoNobel, I designed a paint package based on what the user needs. This resulted in a fundamental change in the interaction with the package.

Advanced Concept Design Sept ‘16 - Jan ‘17 Research and design for AkzoNobel

Before painting, the paint is often poured into a plastic painting tray. A wrong estimate of the amount of paint needed, means paint goes to loss.

Also the tray is an extra product, which has an impact on the environmental footprint of the painting process.

The paint package should provide more functions to make painting a cleaner and more convenient experience.

Non-painting related products should be eliminated as much as possible, to lower the barriers a customer feels when planning on painting.

Our research showed that DIY-painters miss the knowledge and patience to use the traditional paint can as it is intended. The result is an inconvenient and dirty painting process.

The painting tray is integrated into the package and the user can determine how much paint he wants on the tray.

The package is inspired on the traditional “Miura� folding patterns. It utilises the geometry and flexibility of the material to give it spring properties.

This angle effects the initial height the package has and the force that is needed to totally press the tray down.

A stress test with 300N on the side surface of the package.

Push the tray down with the roller, till you feel it reaches the paint.

Go on till a desirable amount of paint is on the tray.

Go back and spread the paint over the roller.
