Soles TRIZ Cases

A cleat force mitigation assembly compresses an elastic field via an inclined surface to absorb impact energy.

Stacked insole segments with localized heel stitching reduce leg fatigue by balancing structural rigidity against overall weight.

A bending deformation member with plate portions stores impact energy for restitution, resolving the trade-off between cushioning and stability.

Elongated double curved channels in footwear soles enhance flexibility while deep heel structures absorb impact loads.

Spray-on fabric cures on a 3D printed last to create customized footwear, reducing labor costs and improving fit precision.

A thermoplastic barrier layer prevents tacky gel adhesion to molds, resolving processing difficulties for low durometer viscoelastic materials.

An elevated midsole arch deforms and elongates under load to resolve the contradiction between thick cushioning and flexible fit.

Segmented body parts with graduated Shore C hardness create a medial-to-lateral gradient that induces foot pronation without external training mechanisms.

A cleat assembly with 360-degree tiltability absorbs impact forces through a spring-based post.

Variable height cleats with concave recesses fit convex midsole protrusions to enhance grip and shock absorption without increasing overall weight.

Segmented air tubes and a honeycomb bladder resolve weight-durability trade-offs while maintaining optimal shock absorption.

A shoe sole shock absorbing member uses a seamless connection member inserted through support member tubes to maintain stable attachment during elastic deformation.

Laser partial vulcanization eliminates multiple molds, reducing production time and costs for customizable shoe soles.

Hollow microspheres expand during molding to create a low-density cellular structure that absorbs impact energy without structural collapse.

Rigid bracket with tubular holders secures cleats to a deformable sole, enabling tool-free removal via self-service mechanisms.

Curved leaf springs maintain restoring force during compression, solving power loss in footwear.

A gradient strike pad absorbs impact forces to reduce stress on lower extremities during running.

Thermocompressed textile soles merge insole, midsole, and outsole layers into one piece, eliminating stitching waste while maintaining mechanical reliability.

Auxetic footwear soles expand laterally under tension to increase ground contact area, resolving traction limitations in conventional static designs.
