Eyelets TRIZ Cases

A lower-melting elastomer flange enables direct welding of reel-based closure guides to footwear, cutting assembly cost and complexity.

A thermoplastic elastomer flange enables heat-welded reel closure attachment to footwear, cutting assembly complexity and cost.

A thermoplastic elastomer flange enables lace guides and tightening components to be welded onto footwear with lower cost and assembly complexity.

A folded tape member replaces separate eyelets and reinforcements, simplifying shoe upper assembly while preserving lace tightening, fit, and support.

A unitary knit upper integrates the tongue in one knitting process to cut stitching waste, shorten manufacturing time, and improve recyclability.

Slidable eyelets with arc-shaped apertures cut lace friction and improve reel-based tightening and loosening for a smoother footwear fit.

Varying elasticity and low-friction guide surfaces spread lace tension more evenly, reducing wear, pinching, and frictional locking.

FFF-deposited thermoplastic zones reinforce footwear textiles where needed, improving abrasion resistance, flexibility, and moisture management.

Aligned lace openings and internal gussets improve midfoot and forefoot containment while keeping footwear lacing simple and supportive.

Tunnel sections and connecting channels let laces be routed at selected points, improving fit customization without spoiling shoe appearance.

Multiple transverse fastener sets let the upper adapt to different foot widths while preserving a snug, breathable fit.

A unified knitted butterfly workpiece with reinforced joins improves footwear fit and flexibility while preserving upper support and stability.

Stiffer lace-receiving members reinforce the upper to secure the foot during explosive lateral movements without overcomplicating closure structure.

A unitary knitted footwear upper integrates the tongue and inlaid support strand to cut stitching waste, simplify manufacturing, and improve recyclability.

Conventional footwear leaves the lateral forefoot unsupported; a heel-counter-backed strap adds adjustable tension to resist ankle inversion during plantar flexion.

Fixed auxetic geometry limits a knitted component's stretch tuning; a tensile strand changes the portion's area and shape for selective adjustment.

Hydroentanglement embeds element scrims in fiber layers to place functional characteristics locally without adhesives, reducing waste and assembly steps.

Lace-tensioned supports across a footwear upper deliver customized regional support while reducing energy drain during running.

A cage, sleeve, and medial and lateral wings separate lacing zones to reduce overlap, friction, and pressure points.

Formed during knitting, arc-shaped anchor channels guide a tensioning cable while reducing added components and assembly complexity.

Adjustable heel support adapts to individual foot dimensions, helping secure the heel and reduce discomfort and blisters.

A movable heel element adapts around the wearer’s heel, separating heel support from instep tightening to reduce slippage and discomfort.

A routed cable closure and medial-lateral stabilizer adapt footwear tension and support to different gait patterns.

Segmented apertures in a continuous lace guide accommodate diverse foot shapes without adding closure complexity.

Semicircular guides minimize frictional wear on laces and flaps, allowing continuous tightening without snagging or repositioning.

Longitudinally extended channels form within knitted shoe uppers to create rigid engagement elements that prevent lace loop rupture under stress.

A moveable assembly with a hinge and flap adjusts footwear fit for easier entry.

A 360 degree lacing system uses external fairleads to guide a slidable lace for secure footwear fitment.

Filament loops extend from the woven body fringe to anchor shoelaces, preventing irreversible deformation of the mesh structure.

A dynamic ankle brace uses elastic cords to permit natural joint movement while resisting excessive displacement.

Dynamic tensioning cords adjust resistance based on ankle position to prevent excessive motion while maintaining full functionality.

Embroidered strings form inward loops on a knitted vamp body to create firm protection eyelets.

Injection molding forms a monolithic skate boot integrating multiple structural portions to eliminate assembly complexity.

Segmented lace segments and a detachable hook-and-loop pull-tab resolve the trade-off between rapid tightening speed and component replaceability.

A golf shoe upper integrates a rotary dial lace tightening system to secure the instep region around the foot.

Segmented side panels with stretchable portions move with the foot to reduce compression and slipping during wear.

Integrally knitted eyelets form lace openings directly within the shoe upper structure during fabrication.

A knitted footwear upper integrates an inlaid strand within fusible and non-fusible yarns to provide structural support.

Segmented strands in a chain-link configuration distribute tensile forces across the upper, eliminating hot spots and ensuring proper foot positioning.

Branching a single lace into two strands eliminates friction loss at eyelets, ensuring even tightening force across the entire foot.

Segmented weighted members attach via shoelaces to distribute mass evenly, resolving discomfort from concentrated pressure on the foot.

Concealed elastic band across the forefoot opening prevents slipping during movement while maintaining a lace-up appearance.

A UV curable microlattice structure forms varying density regions within footwear components to optimize mechanical properties.

A footwear vamp integrates a yoke to form a lace tunnel, creating a compact tightening system.

An ankle brace uses dynamic tensioning cords to allow natural joint movement while providing structural support.

Segmented magnetic clips attach to garment loops, enabling symmetric gathering while avoiding permanent alterations.

Segmented eyelets with nested shanks merge fastening security and ease of operation while elevating laces off the ground.

A reconfigurable fastening system uses segmented eyelet rows to contour footwear uppers to varying foot shapes.

A sliding sleeve clasp mechanism secures interchangeable jewelry elements through elastic retention of a dual-arm pin.

A lace fitting structure with longitudinal and transverse laces accommodates foot shape changes through exposed engagement areas.
