Hierarchal Customer Needs List
From our initial problem statement, the team had
the goal of making the toothbrush as reusable as
possible. After taking the surveys of toothbrush
users, however, we found that the most important
thing they are looking for is cost and then aesthetic
appeal . The new goal of the design is to make the
electric toothbrush as cost friendly to the consumer
as possible. The reusability was also found to be
important in a consumer’s decision to purchase a
toothbrush.

How does it work?
• Chargeable Station
• Electrical Energy is transformed into Chemical and then Mechanical Energy
• Gears turn the brush head
