Customer needs
Customer Needs

The team has decided that the portability and powering of the toothbrush are most important and thus will be primarily focused on.

The team also decided that while some power features and extras are important, others would be too complex for a simple electric toothbrush.

Final design cont
Final Design, cont.

  • Brush Head- linear movement bottom brush, rotational movement top brush, fixed linearly

  • Scotch yoke- linear motion controls tongue scraper

  • Cylindrical lithium ion battery- speed settings and power button. Not rechargeable in body, life expectancy is 6 months

Final Remarks

Conclusion

As engineers, we strive to make life better by constant innovation.

Extent of Success

We have collectively generated ideas, and managed to put them in the final develeopment of the concepts that led to the final design.

Our electric toothbrush design has become a multifunctional equipment with the addiction of the unique features such as tongue scrapper, lithium ion battery, speed settings, etc.
