Soles TRIZ Cases

A bladder supported in a chassis uses outsole protrusions and apertures to spread impact forces and improve cushioning at the metatarsophalangeal joint.

A metatarsal-head depression and radial cleat layout preserve traction while reducing foot fatigue, pronation, and knee stress.

A two-piece sole plate separates chassis strength from traction profiles, enabling lighter cleated footwear tailored to sports and surfaces.

A rigid pedal-coupling plate between cushioned layers lets one shoe deliver cycling power transfer without sacrificing running comfort.

A thicker curved inner forefoot sole concentrates thenar pressure and returns it as repulsive force for smoother kick motion.

Zoned expanded TPU and TPU-free sole regions enable steam bonding to the upper while improving cushioning, stability, and assembly efficiency.

A flexible inner layer joined at the front and released at the rear enables hands-free entry while avoiding rigid, costly heel structures.

A carbon fiber plate embedded in the sole boosts MTP joint stiffness, energy return, stability, and traction during running.

Electrode-controlled ER fluid shifts between sole chambers to switch footbed incline for straights and curves, improving running biomechanics.

Raised heel protrusions and localized sole thickness keep footwear slim in profile while preserving cushioning, support, and durability.

A slatted heel support bends under foot pressure to keep rear support while enabling hands-free shoe entry, removal, and heel alignment.

Thermoformed plastic sheet moulds replace complex metal tooling for outsole and insole curing, speeding design changes and production.

Elastic compression in a shoe sole pumping assembly circulates air to vent heat and moisture and keep the shoe interior comfortable.

Separate medial and lateral reinforcing bars tune midfoot rigidity to improve cutting support, propulsion, and arch stability.

A bistable sole bending module widens the shoe opening for easy entry, then returns to a stable shape for secure wear.

Directly printing functional layers onto a shoe upper replaces multi-part assembly, enabling precise zoned support, cushioning, and lower waste.

A tilting shoe sole with embedded gyroscope and accelerometer data enables intuitive VR motion tracking without handheld peripherals or external sensors.

Chemically compatible polyester upper and sole enable glue-free molding, lower-energy production, and repeated recycling into granules.

A shared upper midsole and varied lower midsoles create different sole angles for forefoot or midfoot running while cutting mold cost.

A slotted polymer core and controlled bond pattern keep the bladder flat before inflation while preserving fluid communication and cushioning.

Wavy-bonded polymer sheets tether the footwear bladder to keep it flat before inflation and resist repeated stress and delamination.

A soft- and firm-density golf shoe midsole redistributes load to improve swing stability while preserving walking comfort.

A plated sole with forefoot fluid bladders and separated heel cushioning balances impact absorption with stable support for HIIT movement.

Variable-width grooves create layered shearing in the sole to absorb impact better while reducing the hard wearing feel during walking and running.

Expanded particles are loaded from top and bottom openings to surround a functional element, simplifying shoe sole molding and enabling customizable cushioning.

Pre-compressing and heating open-cell footwear foam locks in collapsed cells, improving durability while preserving cushioning comfort.

Injection-molded thermoplastic and adhesive bonding replace manual sole coloring to speed production and prevent fading or streaks.

A cradle-supported bladder and cushioning element improve heel impact attenuation, support, and responsiveness in footwear soles.

A motor-driven lace and sliding closure tighten or loosen footwear automatically to balance secure fit, comfort, and ease of adjustment.

A midsole plate and preassembled lacing engine cut assembly complexity and cost while keeping automated footwear serviceable and customizable.

Dispersed low-modulus elastic bodies in foam-particle resin soles preserve soft cushioning while limiting deformation under high loads.

Independent bladder inflation with a compressor and solenoid valves adapts plantar support to foot movement, improving comfort and stability.

Transparent strobel and insole regions expose the bladder and inserts in a footwear sole without sacrificing comfort or function.

Fluid-linked instep and arch chambers shift pressure through sealed lines to deliver dynamic foot support without pumps or valves.

A notched footwear bladder aligns with the metatarsal heads to improve flex, cushioning, and targeted support during foot movement.

Controlling mold temperature and gas counter pressure keeps foam injection stable in thicker footwear parts, improving density and surface quality.

Segmented forefoot and heel bladder arrangements improve zonal cushioning, support, responsiveness, and sole durability during athletic movement.

A longitudinal insole channel relieves plantar fascia and heel tension while preserving foot support and controlled supination.

A unitary knitted sole vacuum formed with cleat members cuts assembly steps, removes joint failures, and improves recyclability in footwear.

Custom inserts and an elastic spring plate tune flex, torsional stiffness, and traction to stabilize foot movement during golf swings.

Alternating leaf-spring ribs let an insole arch support bend with high heels and flats while maintaining support and reducing stress.

Heat and pressure bond sorted waste yarns into quality textile components without added adhesives, cutting recycling energy use and waste.

A removable stelo and locking heel let one shoe switch between high heel and flat modes, improving comfort without carrying extra shoes.

A flat non-trimmed sole is bent around the upper to create 3D shoe shapes with less mold complexity, waste, and assembly effort.

An integrated footwear plate and arced shield redirects external forces to assist movement while preserving flexibility and foot protection.

A segmented fluid-filled bladder uses connected heel-side chambers and a web area to balance cushioning, stability, and durability under varying loads.

Breathable grooves, side through holes, and a waterproof membrane vent sweat from the sole while blocking water entry and supporting shock absorption.

Injection molding through aligned upper and strobel perforations forms an internal cavity bond that improves sole attachment durability in molded footwear.

Modular mold cartridges and aligned vacuum ports form textured footwear bladders with lower tooling cost and less mold inventory.

Segmented midsole pockets absorb vertical and horizontal forces while preserving lateral stability and push-off force transfer in sport shoes.
