Customer Needs
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
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.

Final Design
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?
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
