Mobile Phone Case with Sensor & Camera Protection
70 patents in this list
Updated:
Modern smartphone cameras integrate multiple sensors, lenses, and processing components into compact modules that protrude from device bodies. These modules face daily exposure to micro-impacts, with testing showing that typical pocket insertion generates forces of 3-5N, while drops from 1.5m can subject components to peak forces exceeding 300N.
The fundamental challenge lies in protecting sensitive optical and sensor components while maintaining image quality and preserving the slim profile that consumers demand.
This page brings together solutions from recent research—including retractable lens covers, anti-reflective hood designs, specialized lens coatings, and integrated filter systems. These and other approaches demonstrate how manufacturers are balancing protection with functionality in modern mobile device cases.
