Germicidal Toothbrush

This was a design project associated with an extra course I took up. 
Toothbrushes are generally kept in areas with high bacteria concentration. The moist surface of the toothbrush can further facilitate this growth. We were tasked with designing a superior toothbrush that would fight this issue.

Following  a comprehensive market study of the available toothbrushes, interaction with the targeted group of customers and reforming the primary goals, a problem statement was defined.

“Reformation of the traditional toothbrush to improve hygiene and protect the environment while ensuring affordability”

Ideation

The proposed design draws inspiration from fountain pens. Fountain pens work on the principle of capillary action, where a liquid will be drawn along a narrow tube. When you put the nib on paper and drag it along, the ink is pulled down a slit in the center of the nib, and down the feed, by capillary action. 
A similar mechanism can be used for drawing the antibacterial solution (or mouthwash) to the bristles of the brush, thus cleaning it. 
Additionally, the waste generated is reduced and only a small component of the brush requires regular replacement, thus cutting on costs.
