  5. Step 2:Revised Problem Statement Our design problem is to design an inexpensive electric toothbrush that, above all else, functions well. Considering customer needs, we have determined that the design must have a long battery life and must be fairly user-friendly. Our team has decided to focus on minimizing the quantity of materials used in the toothbrush body and power usage.
