Soles TRIZ Cases

Zoned lattice density and orientation tailor cushioning and support across the sole while additive manufacturing preserves regional customization.

Radiating sipes divide the sole into movable segments that balance natural foot flexibility, arch support, and pressure distribution.

A bladder held within a cradle combines resilient cushioning and structured support to distribute heel forces and improve comfort.

Segmented plate sections between cushioned sole layers provide targeted foot support, improving stability while reducing energy dissipation during movement.

Combining polyolefin copolymer, resin modifier, and TPV helps footwear soles resist chunking, scratching, fracturing, and cold-condition stress whitening.

Flanged traction members fit through outsole openings and anchor at the top face to improve grip and stability across surfaces.

Replaceable mechanically fastened inserts let a footwear outsole provide different friction levels by location, avoiding VELCRO® wear and frequent shoe replacement.

An inwardly-protruding bond aligns flexion axes with foot joints while tethers support staged cushioning and consistent shape recovery.

A heel pocket filled with visible cushioning particles helps balance footwear comfort, responsiveness, and ground-reaction force attenuation.

Continuous-fiber 3D printing builds sole plates with angled layers for customized stiffness and support while reducing material waste.

Crushing, aeraulic separation, and devulcanization help retain recycled ball material in durable shoe soles.

Concentric annular traction zones align blade cleats and omnidirectional elements with movement paths to reduce torsional resistance.

Segmented tensile members preserve chamber shape while creating flex grooves that improve flexibility and comfort in athletic footwear.

A pressure and temperature feedback loop stabilizes molten polymer injection, improving cell-size consistency and molded-product repeatability.

By integrating a lasting element into the knitted upper, footwear can be tightened around a last without a strobel, reducing seams and assembly steps.

Translucent or transparent strobel and insole layers reveal the fluid-filled bladder while recessed inserts remain flush for cushioning support.

A molded outsole merges a rigid toe-cap with flexible material to eliminate weak junctions and improve wear and impact protection.

Layered outsole, midsole, and insole construction combines durable protection with flexibility, while arch support and comfort zones relieve foot fatigue.

A softer medial midfoot twist allowance follows foot rotation, while a harder bend restraint supports turning stability.

Localized stitching creates flex grooves in fluid-filled sole chambers while preserving a substantially planar shape during inflation.

Fixed bowling soles require multiple pairs for different lane conditions; interchangeable foreparts and heel parts let one shoe adjust traction.

Distinct outsole traction zones improve golf-shoe stability while distributing contact to reduce turf-trenching.

The inclined sole transition makes toes buckle during walking, training arch muscles without elastic bands or other external aids.

Downward convex protrusions cushion heel contact while an arced midsole profile supports smoother heel-to-toe momentum.

A high-RSV copolyester elastomer foam preserves cell-wall integrity for low density while minimizing cracks and plasticizer use.

Interconnected cushioning lobes compress resiliently to balance heel support, responsiveness, and energy distribution under foot loads.

A top-loading spool adjusts lace length inside the sole cavity, helping address fragile mechanisms and complexity in automated footwear.

Segmented foam pods target heel, midfoot, and forefoot cushioning while a forked chassis improves support, flexibility, and energy efficiency.

Separate massage devices can make multi-area treatment time-consuming; integrated LEDs and vibrating motors target the foot in portable footwear.

A hinged sole uses pivoting midsole components and friction to hold an access position for hands-free foot entry.

Lobed support and expansion chambers differentiate heel and forefoot cushioning while a flexible barrier layer retains fluid pressure.

Repeated loading causes EVA foam to lose resilience; a graphene, OBC, and butyl-rubber compound reduces compression set.

Steam heating can fuse particles unevenly in curved soles; a permittivity-tuned insert shapes electromagnetic energy for consistent cushioning.

Three sealed gas-filled cushioning layers vary stiffness to stage load absorption and improve energy return in a flexible midsole.

Through-holes physically bond 3D-printed reinforcement to foamed resin, improving strength without compression molding.

This shoe uses a localized medial rearfoot bulging part to restrain overpronation without disrupting landing comfort.

This case shows how a sole-plate cavity organizes motorized tensioning components while supporting torsional rigidity and customizable fit.

This case integrates complex sole inserts during midsole molding to preserve integrity, traction, and tailored flex.

Tightened tensile members compress segmented sole supports to customize cushioning, stiffness, and stability.

This footwear case uses a removable lattice frame and supercritical-foamed midsole to customize support and replace worn outsole sections.

A harder medial band, softer midsole, and arch support structure provide dynamic support while preserving comfort.

Removable midsole and outsole parts enable footwear customization and easier recycling.

Vacuum suction drives dye 0.08–0.12 mm into outsole micropores, improving pattern quality and resistance to peeling.

Segmented panels and fluid-filled chambers help open the upper while cushioning ground-reaction forces for better support.

Distinct auxetic aperture patterns tune energy absorption, lateral stability, and cushioning across heel and forefoot zones.

Different polymer melting temperatures let one knit textile form functional zones with less cutting, assembly, waste, and time.

This footwear case uses segmented carbon-fiber plates, heel support, and foamed cushioning to limit energy dissipation.

A removable foot cover and base use Velcro or snap-fit couplings to switch soles while preserving grip, cushioning, and comfort.

Taller protrusions deform first for cushioning, while shorter ones engage later to add support and resilience under increased pressure.

This case uses resilient cleat bases and segmented structures to absorb lateral loads while maintaining ground engagement.
