2. something about me
Ever since I was a child I had a passion for
technology and for how things work. I was de-
termined to be an inventor. After high school
I was eager to start my academic education
in industrial design engineering.
During my education I realized the responsi-
bilities of an industrial designer when design-
ing products for the people on this planet. My
mission is to design meaningful products that
significantly improve our lives without com-
promising the environment.
I love connecting with people from different
parts of the world to experience more than
what the Dutch culture has to offer and to
broaden my horizon. I believe there is a lot to
learn from the diversity in cultures and that
it is increasingly important for designers to
have an extremely open mind to be able to be
creative and innovative.

3. agricultural
machinery
This concept add-on for all terrain vehicles was designed for
Schuurman BV as my final bachelor project. It enables usage of
agricultural machinery such as log splitters, mowers and mini bal-
ers. The torque provided by a gasoline engine is converted in hy-
draulic pressure and torque similar to a mini tractor.
Design brief
Design an innovative
product to increase
the functionality of all
terrain vehicles in the
context of agriculture.
Solution
With this power take-off system
an all terrain vehicle will acquire
the same functionality as a mini
tractor.

4. Design brief
Design a stairlift for elderly that
reduces the stigma of being for
old and dependent people.
Solution
The stairlift is a platform
with a seat that can be
leaned on. The steer is
tilted slightly forward
to move forward.
This stairlift is the result of an advanced concept design course
commissioned by ThyssenKrupp Accessibility. The aim of this final
concept was to reduce the stigma by giving the product a luxu-
rious appearance. The sketches below show an idea generation
session that lead to the final concept.

5. Design brief
Design a device that
prevents ankle buck-
ling during ice skating.
Solution
An ankle stabilizer with a car-
bon fiber shell. The product
consists of two parts that can
easily be mounted on and off.
This was a group project and my main focus was the translation of
partial solution sketches in to a 3D CAD design. I designed carbon
fiber shell and the mold for it.
A prototype was made and tested using a high speed camera that
was mounted on the ice skate. The trajectory of the ankle was
then measured with and without the ankle stabilizer to see how
much the ankle buckling was reduced. The deviation of the ankle
with the ankle stabilizer is represented by the red line below.

6. Design brief
Design an innovative prod-
uct for Maars Partitioning
Systems BV.

narrow
4-way corner
3-way corner
2-way corner
Solution
A modular partitioning system
that is designed for flex offices
In this group project I was also responsible for the translation of
sketches in to a 3D CAD product, stress simulations and renders.
The partitioning system is completely made out of aluminum ex-
trusion profiles and panels. These panels vary from glass, plastic,
steel to even special materials like texteel. This way any kind of
space divider can be created for any type of working environ-
ment with any additional purpose. They have been optimized in
weight so that any person can build or reposition their space di-
vision.

7. reclining
chair system
Design brief
Design an ergonomic reclining chair
mechanism that is adjustable in size
for Well-Fair BV.
Solution
An ergonomic chair, adjustable in all sig-
nificant dimensions. Biomechanically op-
timized to prevent discomfort induced
by shear forces.
adjustable dimension
upholstered for
user testing
The mechanism was designed with a user centered approach; re-
search was done in to the user activities in the recliner. Then the
inclination angles of the seat, backrest and footrest were defined
with a biomechanical model. The backrest was designed so that
when inclining, the shirt pull effect would not occur. After building
a prototype and user testing it was concluded that the theory of
this design was valid.

Demand
Design a 3D human model in SolidWorks
that can be used as a reference in a
control room designs.
The 3D human models are able to change their size and posture
with one mouse-click. The models can sit straight, sit slumped,
stand straight, shake hands and walk. The models give an indica-
tion of the size on the objects in the designed environment and an
impression of how the environment would look like in use.

10. rapid
prototyping
This airplane was modelled in Rhinoceros and 3D printed for an
elective course. A demand was to use as few material as possible
so I demounted the wings and created cavities so they could be
attached after printing. Moving parts where also directly printed
and cavities were left for an alien object (magnets).

13. presention
drawing
This Kawasaki motorcycle was drawn with white chalk
on black paper and was an exercise to better under-
stand realistic shading and reflections. (2012)

14. surface
modelling
With surface modelling in SolidWorks or Rhinoceros I can model
organically shaped products. I modelled this BMW as a challenge
and an exercise to see how I would pull it off. (2013)

15. motion
analysis
This toy airplane was modelled in SolidWorks as an exercise
in modelling, moldflow analysis and motion analysis. There-
fore it contains advanced mates that make the model move
according to the gearwheel ratios.
The propeller was used for the moldflow analysis where an
optimum in temperature, wall thickness and injection location
for injection molding was found.
