Soles TRIZ Cases

An open-cell ventilation chamber in an injection-molded sole uses a side-mounted non-return valve to prevent dirt clogging and maintain breathability.

A segmented shoe outsole uses overlapping sole segments and cushion elements to provide traction.

Optimizing the weight ratio of activator to unneutralized carboxylated olefin copolymer improves compression set resistance and durability.

Flexible front vamp nests into outer sole to convert footwear between shoe and sandal configurations without carrying separate components.

A shoe sole member integrates resin foam particles with non-foamed elastic bodies using a shared polyolefin or polyurethane base resin.

Merging insole, midsole, and outsole into one 3D printed component eliminates labor-intensive bonding steps while maintaining structural integrity.

A mechanical ventilation system uses a peristaltic air reservoir to circulate fresh air through footwear with every step.

Segmented stability pods on a flexible base resolve the trade-off between lateral stability and foot flexibility, reducing blister risk.

Annealing or additives raise the melting onset temperature of a TPU outsole, preventing deformation during steam molding while enabling adhesive-free bonding.

Modular LED units slide into grooves of shoes or boxes, replacing fixed lamps to solve adaptability and safety trade-offs.

Movable outsole segments linked by flexible members expand the footwear structure, resolving inventory complexity from fixed size variants.

A wearable cleaning shoe uses bristles to scrub floors while a grooved heel stabilizes the user.

Curved tread patterns prevent slippage during athletic torque while avoiding member catching.

Footwear synchronizes light emission with music and movement, resolving the trade-off between interactive adaptability and system complexity.

Dual precipitated silica moieties improve wet traction while resolving the incompatibility between hydrophilic silica and diene-based elastomers.

Segmented molded sole with adjustable metatarsal pad secures dog boots while accommodating varying paw sizes.

A massaging shoe pad uses movable plates to create adjustable bulges that press against sole acupoints for targeted massage.

Segmenting decoration from structure creation reduces build time by one-third while enabling variable bulk density in athletic footwear.

Upwardly protruding lug on connecting sole engages hook-shaped outer sole rim, resolving side-force instability without additional fasteners.

A shoe midsole damping element uses a solid piston inside a hollow cylinder to adjust cushioning properties.

A footwear sole assembly combines a unitary lattice structure with a compression foam insert to deliver mechanical support and cushioning.

A bimodal shoe structure snaps into positions using directional bending forces to enable hands-free donning.

Detects interacting conductive elements via machine-to-machine communication to resolve visual obstruction disputes in sports.
