Overview
- The U.S. Patent and Trademark Office granted Apple a patent titled “Electronic device having a shock-resistant haptic engine.”
- The design uses non-linear cantilevered springs with varying thickness and chamfered edges to soften minor shocks and stiffen under heavy loads.
- During an impact, a movable mass suspended on flexures is guided toward spring assemblies in the enclosure lid to lengthen force distribution time and reduce failure risk.
- Patent figures depict smartphone and watch implementations that prioritize durability gains without increasing size or weight.
- The grant signals active R&D, and there is no confirmation of near-term product use, with multi-coil or richer feedback claims remaining speculative.
