Helmets TRIZ Cases
- Helmet Fitting Band With Elastic Auto-Adjustment Mechanism
An elastic fitting unit and gear-coupled adjustment mechanism let the helmet band self-fit the wearer's head without repeated manual tightening.
- Helmet Fitting Mechanism for Hands-Free Elastic Adjustment
Elastic expansion and contraction let the helmet fit automatically during wear, while adjustable force balances secure retention and head pressure.
- Hard Hat Ratchet Gear Assembly to Prevent Accidental Loosening
A segmented ratchet gear and self-locking band housing keep hard hat bands easy to tighten while resisting accidental loosening.
- Wearable Hydraulic Shock Absorber for Temperature-Stable Impact Damping
Liquid ejection through tuned orifices dissipates impact energy and maintains stable shock absorption across low, medium, and high impacts.
