Soles TRIZ Cases

Unneutralized carboxylated olefin copolymer blends resolve compression set and shrinkage issues in polyolefin footwear foams.

A footwear design uses a dense heel insert to shift the center of gravity for stable upside-down placement.

A rigid carbon fiber plate maintains outsole shape while a weight-distributing channel directs force to the outside portion.

A bicycle shoe sole uses dual rigidity materials to balance pedaling efficiency with walking comfort.

Variable hardness pads on the shoe sole correct uneven pressure distribution and prevent foot distortion by maintaining a 90-degree heel angle.

A separable upper and lower insert creates an internal injection channel within a mold cavity.

Segmented sole grooves and concave sidewalls provide enhanced grip, resolving insufficient traction for wall and rope climbs.

A multi-mold injection molding system forms distinct material layers sequentially.

Protrusion strips guide the foot pressure center along a specific path, reducing skeletal strain and improving propulsion speed.

A sole plate with a tapered forefoot through hole creates differential stiffness in footwear midsoles.

High-styrene rubber outsole balances wet grip and uneven terrain adaptability through silica reinforcement.

Segmented transverse blades distribute force to reduce over-pronation risk and improve stability without increasing midsole stiffness.

A breathable and waterproof shoe sole uses a polymeric overmolded structure with a permeable insole to manage foot environment.

A footwear pressure sensing system monitors foot load via distributed sensors to provide real-time data.

A shoe midsole uses a harder elastic peripheral band and a high-hardness insert within a softer core to reduce heel sinkage and improve weight distribution.

A mesh substrate layer protects soft midsole sidewalls from abrasion, resolving the trade-off between cushioning performance and durability.

Compressible bladder drives fluid through a pneumatic motor to generate electrical power, overcoming low deflection limits of piezoelectric footwear.

A footwear sole assembly combines a soft cushioning midsole with a rigid support frame to deliver targeted structural reinforcement.
