When we peel an orange with bare hands, our hands easily get wet with the sticky juice effusing from the peel. There are fruit knives and several existing citrus peelers to help people for peeling oranges, but I thought those tools are not helping the whole process of peeling or not quite convenient enough to make the process much easier. I tested existing peelers and also researched current ways of citrus peeling and found out that the easiest way so far is using a knife and then a spoon. In order to use a spoon, at first we need to make an access opening with a knife, so I started from combining those 2 functions. The first trial with 3D printed prototype was a total failure and I kept trying the make-and-test process with styrene sheets and a heat gun. At the final stage, I applied a sharp tooth to make the initial opening and also hid the tooth inside the rim because I want it to be safe enough for children as well. When I solved the functional problem, I also tried to refine the appearance aesthetically, because I wanted it to be intriguing and beautiful enough to be placed on a table.
