4.  Based on our survey results, we concluded that customers are only willing to pay between $10-$20 for an electric toothbrush. Also, customers were more interested in an aesthetically pleasing toothbrush.  Revised problem statement- Our assessment of our original toothbrush told us that we needed a more sustainable battery along with new brush heads and we wanted to make it more aesthetically pleasing. Most of these characteristics can be accomplished through a new design of the toothbrush. Our problem now will be to construct a better and more efficient toothbrush based on our assessment and redesign process. Customer Needs Part 2

5.  Through our external searches, we determined different parts to the toothbrush that have been designed before and could be used for our design.  Benchmarking helped us understand the strengths and weaknesses of the different toothbrush out on the market. External Search

12. Final Design

13.  Head technology- two reserve spinning circular heads  Energy mechanism- two ribbed rubber bands spun by motor that is attached each head, which are both on their own pivot points  Power generation- rechargeable deck for toothbrush to charge in when not in use that is plugged into a wall outlet  Body design- convex for easily fitting into the hand of the user and a switch for easier on/off ability; timer that counts down from two minutes when you turn it on How does it work?

14.  Cost was a main consumer concern, so we took measures to reduce cost  We found that the rechargeable deck is not much more expensive than normal battery power, and is much less expensive in the long run for the consumer  For the energy mechanism, our durable rubber bands will be less expensive to produce than the metal rods in the standard toothbrush  The bands will also cause a smoother rotation for better cleaning ability along with the dual brush heads, which satisfies the customers need for better cleaning ability  Timer makes sure that customer knows how long to brush teeth so that they can get a good clean  The convex handle design and on/off switch add to the aesthetics and the ease of use Concluding Remarks
