1) How did working through different materials help you to explore and express potential solutions to a design problem?

At first, being required to only use corrugated cardboard to make a chair prototype was knotty as far as I am concerned. I believe it is quite tough for my prototype to keep standing. Just in a unexpected moment, mortise and tenon popped into my mind, which is a great architectural invention in China and  can improve the mechanical performance of ancient wooden building. Definitely I can learn from it when assembling chair legs.

pipe cleaner is a kind of optimal material in this case. It is flexible and under control. I feel comfortable working this tool, even though the prototype didn’t look sensational. But anyway it did help approach my vision as close as possible.

Sadly, I wasn’t able to achieve a prototype by toothpicks. It was really hard to make a circle even I broke them into pieces. I realize that material choosing is very important in prototype making.

2) What kinds of information and inspiration did the different materials give you? Did you have a favourite material?

As I mentioned before, choosing material and connecting ways are crucial when making a prototype. Undoubtedly, pipe cleaner is my favorite!

3) What did you change along the way? What did you learn from your prototypes?

When using different materials, I have to change some details to make the prototypes to suit my principles(safety and comfort). Finally, I found each type of material had its advantages when making a chair.

4) How well did you address your user needs in the various design models you created?

I hope my chair is safe and comfortable. Pipe cleaners make the whole chair’ edges are smooth and not so sharp that hurt the baby. Toothpick make the legs of chair strong and stable. Cardboard allows a pleasant seat.
