Helmets TRIZ Cases

Segmented passages route air through a defined space between the plate and shell, reducing noise while preserving mechanical strength.

A strap divider with a rotatable cover plate and base plate post connection.

A helmet chin guard combines a flexible surface layer with a rigid core member to enable swiveling motion.

Nested dual helmet shells convert between combined and separated states, resolving the conflict between rider protection and vehicle storage space.

A gap adjustment mechanism with an elastic member controls air infiltration between a rotatable chin guard and helmet body to reduce noise and drag.

Rear coupling portion with integrated locking means stabilizes removable chin guard, reducing wind drag and sail effect.

A layered composite helmet liner mitigates traumatic brain injuries by dissipating blast shockwave impulse through shear thickening fluid and viscoelastic foam.

Circumferential chin bars with rear and side buckles attach to helmets, resolving weight and ventilation trade-offs during enduro mode switching.

A helmet retention system uses segmented straps and buckles to tighten the fit via a direct pull-down motion.

Ribbon-like extraction element enables single-person helmet removal by expanding the base laterally, reducing neck strain during rescue operations.
