Spirit

In my vision, one of the most valuable and inspiring aspects of industrial design is the collaboration with other people. I think a project will lead to a better result when a close communication between different specialists, the end-user and the designers is maintained throughout the entire project. Involving more people in the design process means looking at the initial problem from more different angles. Taking all these different points of view along during the design process results in a deeper understanding and therefor a more fundamental and complete design solution.

I prefer to satisfy my curiosity by working on different design projects performed in various fields of study. This is exactly why industrial design appeals to me. The fact that every project requires me to gain new knowledge and understanding of a specific topic and needs a different approach is a challenge I am more than willingly to accept.

Designing is a creative process that preferably leads to a solution that integrates all the aspects listed on the next page. Different methods and tools can be used, depending on the type of project. These can vary for example from literature research to interviews, brainstorms, drawings, 3D-models and physical models. Often the emphasis of a project is laid on only one (or a selection) of these aspects. In this portfolio the icons on the bottom right of the right pages are indicating which of these aspects is stressed in that particular project.

Finally it is also important to me to take into account the consequences that products can have on their environment. The life-cycle of a product does not end with the use, but also includes the disposal of a product. Designers should take their responsibility for the products they design. This does not only apply to the natural environment, but also to the cultural context in which a product is placed.

Product AestheticsNaturally the main function of a product has direct influence on the aesthetics of a product. However often the aesthetics of a product also serve other functions. For instance:Cultural support: In this case, the appearance of a product can be a tool for the user to express him/herself and the belong to a desired (sub) culture.Usecues: Usecues are aesthetical aspects of a product that help to understand the products handling. Product Semantics: This refers to a more subjective

and deeper meaning of a products appearance. This is often closely related to the context and culture of use.

Product DefinitionIn order to reach a consistent product, it is

important that the physical aspects of the product design are well considered. This is where the product definition comes into play. This is the aspect where the products dimensions, material, (technical) components, and production process are established.Decisive factors are often costs, quality and the product image. If the product definition is done with care a stronger design solution can be reached.

User ResearchSince the user is the one that is actually going to interact with the product, it is very important to take the user(s) of a product into account during the design process. There are different facets on which a product should fit the user:Functionality: The product has to provide the function that the user desires.Physical Ergonomics: The physical use of a product should be comfortable.Cognitive Ergonomics: The most preferable way of interaction is a intuitive one. In order to obtain this, the users expectations about the use of a product should be investigated.

R&DWithout Research and

Development (R&D), innovation in the field of industrial design will

not be reached easily, if reached at all.Thanks to R&D new knowledge about

scientific and technological topics is found. This knowledge can be used in order

to develop new products, processes and services.

Keeping an eye on R&D performed in the field of a project is important to stay up-to date and

generate relevant products.

Coco PanelsCoconut husk is available in large quantities as residue from coconut production in many areas all over the world. A lot of this material is currently going to waste. During this project research is executed in order to find a suitable application of this waste material in the production of a new building material: sandwich panels.

Coconut husk contains a lot of lignin; a thermosetting material that can act as a natural adhesive. Because of the large amount of lignin inside the husk, it is possible to make a natural composite using only the husk material in which the

lignin (matrix) flows out of the cells and binds the husk fibres in order to form a solid material. Heat and

compression are required to create this composite.

Once final testing and development is executed these sandwich panels can be

used for cheap and sustainable housing in economically less

developed areas.

Coco Panels

In order to determine the optimal production method, the process parameters are varied. This resulted in panels of different quality.

The final sandwich panel will be composed of a corrugated core panel with two flat outer panels.

Each of these panels is tested on tensile strength and finally the panels are impregnated with tar in order to make them water proof.

“De Drietand” is a Dutch Delft Blue art studio that produces and sells earthenware that is prepared according to traditional methods. Since the market for their products is shrinking, this project is aiming for an innovative product to turn the tide. The solution is the Blue Balance: A set of tableware and an accompanying serving tray, perfectly suited for breakfast at bed. Thanks to its more modern appearance and functional design, it taps a

new and more successful market. This is confirmed

by market research executed among

people fitting the target

group.

Living KitchenIn collaboration with Philips, an appliance for domestic use had to be developed in order to get its user “in the mood for food”. The Living Kitchen focuses on improving the cooking process, since interviews with people within the target group pointed out that this was seen as a major obstacle to get in the mood for food. This product helps the user

to get inspired and to learn how to improvise, according

to the users own taste.This product consists of a

projector in combination with motion sensors. The user can

operate the system with the use of gestures. This way nothing will get dirty during use. Using a projector has the advantage of a big screen. This enables operation by multiple users which improves the social interaction within the families. Another benefit is the freedom in the placing of the projector;

Improving New Life

The spirit is designed for the VU with the purpose to perform research into Intra Uterine Insemination (IUI). IUI is a procedure in which women who have problems getting pregnant are helped. Semen is injected directly into the uterus, instead of the vagina like in normal intercourse. Human controlled factors, like the insemination speed play

an important role. Variations in these factors could have a negative influence on the chance on

pregnancy. The Spirit is standardizing the process, giving woman a more equal chance on getting

pregnant. By the use of a mechanic system, three different constant velocities of injection

can be chosen. In contrary to an electric system, the mechanical solution does

not decrease the comfort of the patient the vibrations and

noise during the IUI procedure.

HotFrostWhat to do when money and electricity are a

rare treat and the climate is so warm that all your fresh goods perish in an instant?

The HotFrost is designed to solve that problem. This product makes

use of the energy that is at hand and even redundant in these

areas: the residual heat of the cooking process. The vast

majority of the target group use fossil fuels in stoves or

open air for the cooking process, resulting in (at least) 60% energy waste. Observational research in the capital and a rural village in Cambodia pointed out that both the need and the materials are locally present.

One month of contextual research has been performed in Cambodia. This research consisted of interviews (supported by a preference booklet and a guidance booklet) and observational research.

The outcome of this research is used as input for the further

development of the HotFrost.

Parallel to the conceptual design and the technical detailing phase of this project, a prototype is built in order to test the functionality of this product. The most valuable insight gathered during this prototyping phase was the fact that the required vacuum was more difficult to obtain (and maintain) than expected.

When the prototype was ready to be tested, the tests pointed out that the product was acting as expected, only the measured values were too small to be useful in practice. Further research and development is required to get to a fully functional product.
