The Design Challenge -
The primary design challenge was creating a toothbrush that looks fluid & streamlined to give a perception of being gentle on the gum, as heavy and bulky toothbrushes give the perception of being hurtful to the gum. A good grip design needed to have a suitable volume, the right amount of curvature, and anti-slip features to easily allow changing hand positions for different grips and angles, while connoting attributes like clean & healthy gum lines, white & beautiful teeth.
