     In order to design the best possible toothbrush we possibly could we made a morphology tree with many different power, switch, attachments, and accessory options.  Then we went through trial and error with many designs featuring different attachments and machinery to make a top twenty concepts.  Then we narrowed the concepts down to the top twelve designs that would go through screening.  Throughout the screening of the concepts a top toothbrush was discovered and made into our final product redesign.   Shown below are the concepts and the their respective product breakdowns.
