Lacing Hooks TRIZ Cases

A spool-and-stop closure mechanism enables stepwise tightening and loosening while preventing over-release below a lace tension threshold.

A 3D rotary drum encoder replaces fragile planar optics to cut stack-up and improve rotational tracking in motorized footwear lacing.

Internal supports pass through the PCB to redirect sole impact forces to the motor or battery, improving autolacing footwear durability.

A spool-and-knob closure enables stepwise tightening and loosening while a stop mechanism blocks over-loosening below a tension threshold.

Supports extending through the PCB redirect sole forces to the motor or battery, reducing PCB damage in autolacing footwear.

A cylindrical optical encoder cuts fragility and stack-up in motorized footwear lacing while maintaining accurate rotational tracking.

A spool, knob, and stop mechanism allow stepwise lace tightening and loosening while blocking over-release below a set tension threshold.

A split motorized lacing layout hides power in the sole and uses elastic-inelastic upper zones for low-profile, replaceable fit adjustment.

A reel, guides, and tension member replace coarse buckles to give ski boots smoother, high-torque fit adjustment with better comfort.

A split motorized lacing layout places power and control in a removable midsole, enabling low-profile fit adjustment with elastic upper comfort.

A pivoting rear upper and lace-driven zippers widen the ankle opening for easier foot entry while maintaining a secure fit.

A motorized lacing layout splits tightening hardware and removable midsole electronics to save sole space while enabling rapid fit adjustment.

See how a cord, pulleys, and spaced retainers replace shoelaces to maintain adjustable tension and prevent a loose footwear fit.

Modular lace guides and engine housings smooth tension while supporting cost-effective, serviceable automated footwear designs.

This case uses attachable MOG limiters and varied concave gaps to improve grain capture while restricting MOG entry into cleaning.

Rotating cams on a horizontal axis below the rope line use tension to open the grip, eliminating manual easing under high load.

Segmented outsole zones with directional cleats resolve the trade-off between manufacturing simplicity and traction reliability.

A wearable pulley hub uses a textured exterior surface to grip tensioning cables, enabling secure anchoring and easy rotation within compact footwear designs.

A rope take-up device uses a toggle mechanism to synchronize rotation of its parts for efficient string winding.

Elastic tensioning members and floating overlays distribute lace pressure evenly, resolving uneven tightening in motorized footwear.

Rotating spool winds laces to maintain consistent tension, eliminating uneven knots and tripping hazards from loose bows.
