Initiated from a universal design research study, this project re-engineers oral care architecture for individuals managing severe joint inflammation. The objective was to eliminate traditional physical interaction thresholds: namely, the vertical activation force required for standard switches and the fine-motor strain of rotating lock-and-twist brush heads.

To address this, we engineered a zero-pressure touch interface alongside an auto-aligning magnetic coupling system, rendering activation and head replacement completely effortless. The internal chassis integrates a counter-balanced, stabilized motor system to absorb resonant vibrations and reduce muscular fatigue. Externally, a fully recyclable, optically clear transparent shell houses the assembly, combining functional industrial transparency with circular manufacturing principles.
