One of my client’s favorite food was sushi, but she didn’t enjoy it when the sushi had too much wasabi or rice in it. So I had an idea of a machine that decides the perfect amount of wasabi and rice in a sushi. And considering that everyone has a different preference of amounts of ingredients, there are also functions that each person could choose the amounts by pressing the button in front of the sushi maker. They could just press the button they like. For example, less wasabi→ more rice

My biggest challenge was drawing the exact planar figure on the cardboard. As I was drawing the planar figure of my design on the cardboard piece, I accidentally drew the wrong length of the slant line of my design. However, I didn’t notice my mistake until I already finished cutting out all the lines. The line should have been 8cm when I cut it over 9cm and the lines wouldn’t fit in a shape. So I had to cut all the line so I had to cut all the sides 1cm off. But still I solved my problem of the design.

The skills I learned and developed are cutting out the cardboard. I felt like the cardboard was a bit thick and when I first tried to cut it with a paper knife, I had to cut it several times in order to cut out the whole cardboard. And even for some lines I accidentally cut it too short and had to draw and cut it again. But as I was reaching the end of cardboard cutting, I got used to cutting it and I finally could cut it fluently. Compared to the first line that I cut with shaking hands, the last line that I cut was straight and neat.

Overall, I think my prototype was a success because it came out almost the same as the design I thought and drew on paper. And I am proud that I made my prototype into a one big piece of cardboard by drawing the planar figure. (Still, for some pieces I cut them out separately later.) My cardboard prototype came out to be neater than I expected and I am satisfied with it. But still it could have been even better if I had plenty of materials in my home like school.
