  4. Customer Needs Chart

  5. External Search Activities • From the Oral B website, we found current information on how electric toothbrushes are made and looked into patents. • We looked at the recyclability of toothbrushes and materials we can use to make our toothbrush recyclable. • We used another companies toothbrush model that was not electric but was sustainable as a model to offer sustainability ideas. • We looked at how a lot of energy is wasted to gain an understanding of where we could be saving the most energy when designing our toothbrush.

  6. Generated Concepts • To generate concepts, we used the time in class to come up with all sots of ideas. Some were not even feasible but overall, it was helpful. • In the next slides, you can see some of the ideas that we each come up with during this time period.

  16. Final Design • Interchangeable heads • Vibrating or Rotating • Soft or Hard Bristles • Slim body design with all replaceable parts • An combination electromagnetic/USB charger • A rod that vibrates or in a gear mechanism included in replacement heads

  17. Final Design Operations • Electromagnetism/battery power is used to power the toothbrush • While brushing, current is produced and converted within the brush. • Power is transferred to the motor which using a series of gears, will convert the motion to vibrating or rotating in the neck of the toothbrush.
