Fastenings TRIZ Cases

A vacuum chamber in footwear conforms to the foot using atmospheric pressure, eliminating bulky laces and reducing weight while maintaining fit tightness.

Segmented straps attach to a sole-mounted base plate, resolving heel slip in loose-fitting shoes without altering original shoe dimensions.

Segmented elastic design eliminates complex mechanisms, reducing weight and cost while ensuring reliable attachment.

A cable tightening system uses a heel spindle to tension the upper, creating a secure fit without protruding laces on the instep.

An eccentric adjustment device converts rotational movement into longitudinal tension to precisely control clamping force in ski boot closures.

Plastic buckles with metal inserts prevent corrosion while maintaining coupling strength.

Support members extend from an underfoot plate to pull a cradle toward the calcaneus, preventing forward foot sliding on uneven terrain.

A boot buckle uses a swivel lug and dual latching elements to secure the grip in a closed position.

Medial and lateral strap tensioning components cross at multiple locations to eliminate ankle pressure concentration while maintaining secure fit.

Tapered conical surfaces compensate for manufacturing tolerances to eliminate shell-cuff relative movement during skiing.
