Updated:
Modern smartphones face impact forces exceeding 100g during typical drops from pocket height (1 meter), with corner impacts producing the highest stress concentrations. Current glass display technologies, while improving in durability, still show failure rates of 60-80% when dropped onto concrete without protection, leading to repair costs averaging $250 per incident.
The fundamental challenge lies in designing cases that can effectively dissipate impact energy while maintaining device accessibility and thermal management.
This page brings together solutions from recent research—including multi-layered composite structures with shear plates, integrated shock absorption systems, thermal dissipation channels, and selective protection mechanisms for foldable devices. These and other approaches focus on practical protection while preserving device functionality and user experience.
