Reverse Engineering
By: Karly Haralson Original Parts Function of the Part: The main function of the grater is to ease the process of grating cheese or other foods. Problem Statement: The size of the grater is too small and the materials it is made out of can be improved. Brainstorming: - Larger Size
- Add grips on the sides
- Create different design for holes on metal sheet Research: Design Brief Selecting an Approach-
