Fastenings TRIZ Cases

A retaining strap secures a J-shaped hook to footwear, enabling safe removal of loaded hand trucks without toe slippage or parcel damage.

Embedded traction elements with transverse ground engaging members reduce foot pressure points while maintaining athletic grip.

Piezoelectric generator powers electrostatic adhesive sole to augment grip, minimizing rotational traction to reduce sports injuries.

Segmenting the threaded insert from the removable conical body eliminates stripping during repeated exchanges, reducing installation time.

A ski boot selection lever connects to independent adjustment levers and racks to maintain tension settings during configuration transitions.

A minimalist barefoot shoe uses a medial arch pulling member to exert upward force on the foot arch.

Segmented connection elements with complementary grooves replace protruding tongues to eliminate dangerous footholds while maintaining rapid closure.

An articulated upper section transitions to an access position, allowing foot insertion without manual dexterity.

Segmented upper and outer sole spikes prevent water penetration while maintaining thermal insulation.

A quick lacing machine uses a spiral pulley and screw cap to wind shoelaces for secure fastening.

A crampon connection mechanism uses a sliding locking member within an elongated opening to adjust the distance between front and heel elements.

Self-locking pawls engage unidirectional teeth to maintain band tension, resolving complexity versus reliability trade-offs in head mounted displays.
