Fastenings TRIZ Cases

A wearable shoe integrates wheel assemblies beneath the foot to provide stable roller transportation.

Worm gear mechanism pulls tensioning strap in sports shoes, reducing space required for central fastener.

Interchangeable straps attach to a hook-equipped sole, resolving the storage space and cost trade-off of owning multiple complete shoes.

Segmented transversal insert provides structural stiffness while maintaining compatibility with various Telemark and mountaineering binding systems.

Integrated hook and loop fastening reduces bulkiness by embedding engagement elements within the footwear upper, resolving aesthetic trade-offs.

Segmented design resolves durability versus ground sensation trade-offs, while an adjustable sole accommodates narrow and wide paws.

A shoe lace actuation device uses a closed housing to protect internal winding components.

Segmented strap fasteners prevent through-hole wear during reversible footwear conversion.

Segmented flexible shells and a cable reel system disperse impact forces while maintaining wearer mobility.

A shoe closing mechanism extends from the upper along the side to permit easy donning.

Relocating the cable winding winch to the cuff protects components from shear hits while fairlead members extend heel retention along the longitudinal axis.

A thread reel driven by a knob device locks tension via an arresting disk and ratchet mechanism for one-handed operation.

Segmenting the footwear into a swappable vamp and durable outsole extends product lifetime while maintaining secure attachment during wear.

An adapter couples to a rotary device via a coaxial coupler and provides an enlarged handle for user rotation.

A reversible footwear strap features a dual-surface body and detachable end for manual aesthetic switching.

Segmented fairlead inserts distribute tensile loads across larger areas while curved cable channels prevent cracking and extend boot durability.

A motorized cable system tightens footwear laces automatically using a DC electric motor and flexible transmission lines.

Elastic centralizer band anchors to upper eyelets while binding post secures tongue, preventing lateral drift and lace contact.

An adjustable shoe expands via a hitch fastener and straps to resolve the trade-off between adaptability and structural complexity.
