RHYTHM 3

The SOLADEY RHYTHM 3 electric toothbrush generates negative electrons using water and light.

This styling design accompanies the company’s third-generation electric toothbrush model change. It features a clean, minimally contoured form. We aimed for a design that exudes innovation while remaining compatible with everyday life.

To make the unique design with its large solar panel easier to hold, we considered a lofted shape that is parallel from the front and trapezoidal from the side. A large conductive resin is used on the back to accommodate various grip styles.

The clean finish complements the elegant power button and LED indicator.
The grip end is designed to light up when in use, letting users know it’s functioning.
