Slide Fasteners TRIZ Cases

A recessed string attachment structure hides the pull-tab cord inside the slider, reducing visible thickness while preserving easy assembly.

An inclined protrusion guides the slider and keeps separable pin members engaged, preventing closure idling and improving fastener operation.

Water-soluble thread lets metal zipper elements detach without special equipment, improving fastener tape recycling and reducing impurities.

A water-repellent tape coating blocks moisture from reaching stainless fastener elements, preventing saltwater rust without complex carburizing.

A removable sealing member with lugs, cavities, and deformable seals blocks fluid paths in overlapping slide fastener zones.

Fin portions and a recessed stringer edge hide fastener tape during sewing while preserving smooth slider operation and product appearance.

Overlapping bra flaps hold breast pump components in place, freeing both hands while maintaining stable positioning during milk expression.

A one-flange access hole and release tab expose the tear strip while preserving hermetic sealing and simplifying bag assembly.

A multi-ply film with separated melting temperatures enables edge-closure sealing on recyclable pouches at high line speeds.

A rotating operation piece lifts the claw member to release the lock by gentle pressing, enabling a smaller slider without tab-pull interference.

A twill-woven fastener tape reduces film gaps and whitening, preserving softness while maintaining waterproof sealing.

An internal support member keeps retractable enclosure zippers flat and wrinkle-free while simplifying manufacturing and reducing weight.

Rounded flange geometry and offset curved portions cut contact stress, making concealed fastener sliders pull smoothly without biting into tapes.

An inner support cloth and member keep retractable enclosure zippers flat and wrinkle-free while simplifying manufacturing and reducing weight.

Rotating interlocking pull-tabs lock paired zipper sliders without keys or combinations, improving resistance to forced opening.

Woven identification regions encode recycled or plant-derived thread attributes for easy fastener tape traceability and certification checks.

Integrated locking protrusions in a reversible slide fastener slider prevent gravity-driven opening without bulky external locking parts.

Localized PCR and HDPE in zipper flanges and locking members enables food-safe resealable enclosures while limiting odor exposure.

Encapsulating PCR or HDPE within zipper regions keeps non-common materials away from contents, reducing waste without food-contact risk.

Offset web sections let a double zipper unfold in different directions, improving bag access where handling space is limited.

Guide rods, fixing sleeves, and digital markings help thread soft zipper chains through a trolley-case slider and keep shell assembly balanced.

A polyurethane skin and cured adhesive layer water-stop fastener tape without toluene or MEK while preserving softness.

An embedded flexible core sheet in a soft covering member supports the tape and provides lower-cost water-tight or airtight performance.

An assistive track channel built into the flip-up pull tab guides the zipper pin into the slider for easier, more accurate insertion.

A fold-back upper tape covers deflected stitching lines while the lower tape enables mechanical attachment to luggage shells.

Misaligned inner and outer tooth gaps block sharp-object alignment, helping an explosion-proof zipper resist puncture and stay closed under pressure.

A covered stitching gap lets retractable Y-shaped zipper tape hide line deflection while preserving case aesthetics during mechanical sewing.

Protective cavities house tritium vials inside zipper pulls, improving dark-environment visibility while shielding the vials from damage and breakage.

Neighboring weak elements and remote strong elements reduce stop-claw impact when pulling force could damage or separate the stringer.

Interchangeable tracks and interlocking components simplify closure replacement and retrofit installation on devices without pre-installed systems.

Zippered panels simplify hygienic catheter bag access and inspection.

Coil-shaped restraining members preserve fastener concealability under lateral pulling forces.

This zipper assembly localizes PCR and HDPE in selected regions, reducing odor exposure while supporting regulatory compliance.

A slider cover body uses controlled gaps to balance impact resistance with easier assembly and reduced deformation risk.

Holding grooves and branched halves let users crimp replacement fastener elements onto tape without repair-shop equipment.

A segmented slider keeps the pouch closure compact while providing a wider grip for parallel, low-force opening and closing.

A deformable sealing body expands into the fastener's sealing zone, resisting liquid and gas penetration while remaining removable.

A localized protruding portion helps the slider sense stop engagement, preventing unexpected displacement during fastener operation.

An unequal-diameter hole and elastic head enable rotatable auxiliary-part locking without limiting pull tab appearance.

Thermoplastic elastomer fillers and an extension strip compress together to minimize the center gap and protect seam integrity.

A hinged pull tab and limiting groove guide rotation, while a protrusion actuates the lock for smoother, quieter zipper operation.

Concave walls, protrusions, and track branches guide zipper tapes past fabric and debris, simplifying unjamming.

Friction between the puller shaft, pressing member, and guide column enables arbitrary suspension while reducing marks and breakage.

A beveled guide in the bottom stop directs the movable pin into its slot, easing closure and reducing misalignment and injury risk.

Curved elements reduce interference during coupling, helping the slider move with less force while preserving engagement.

This slide fastener uses adjacent upper and lower walls to prevent cloth jamming while preserving a compact structure.

A permanganate and condensed-phosphate solution forms durable colored coatings on aluminum alloy fasteners with simpler treatment.

A loop-linked neckline fastener locks the onesie zipper, blocking infant access while allowing quick parent operation.

This case uses controlled recesses in stopper legs to limit overlap contact, reducing adhesion and uncoated areas during spray painting.

This case integrates zipper placement with frame extrusion to prevent separation and improve bag manufacturing efficiency.
