Slide Fasteners TRIZ Cases

One-piece injection molding of barbed strips and slots reduces production cost while maintaining reliable fastening.

Protrusions on inclined side walls press down a lock member, preventing detachment under excessive pulling force during assembly.

Transversely opposing recesses in leg members distribute clamping force to maintain a flat front surface on slide fastener coupling elements.

A luggage zipper locking device integrates the puller and lock within the junction plane to maintain a flat exterior surface.

Arc-shaped sloped surfaces reduce pressing force required for rotation, enabling easier operation of separable slide fasteners.

A slide fastener element uses a light transmissive coating on the upper leg to produce diverse color changes with viewing angles.

Segmented slide fastener design enables rapid width adaptation through variable extension tapes, eliminating equipment reconfiguration costs.

Interlocking zipper pullers eliminate gaps between sliders, preventing unauthorized access to luggage contents.

A side shifting slide allows single-operation die casting of metal zipper slides, preserving full geometric integrity without converging flat surfaces.

An elastic tab-holder secures the pull-tab to a zip slider body, preventing disengagement and serrated separation during user movement.

Pre-formed closed packets with dynamic adhesives prevent skin irritation and unintended opening during high-speed production.

Segmented sliders require coordinated opposite movement to unlock, preventing child access while maintaining adult operation.

Segmented waterproof seal layers prevent slider resistance and ensure liquid-tight sealing without compromising tape flexibility.

Slider blades feature extended close-contact surfaces that maintain continuous engagement with the fastener stop during operation.

Oblique leg curvature increases contact area to improve lateral pulling strength, preventing disengagement under transverse forces.

Independent single structures in double-bed warp knitting reduce needle load and stabilize ground structure surface uniformity.

Inner positioning of coupling convex portions prevents contact and cracks when slide fasteners bend into a U-shape.

Elongated recesses on box pins and insert pins increase pressing area to stabilize fastener tape positioning during injection molding.

A polypropylene-coated fabric pool cover uses heat-bonded layers to create a durable, lightweight barrier without adhesives.

A sliding push-button closure system for athletic gloves enables one-handed tension adjustment via a notched slide bar.

A side shifting mold mechanism forms an integrated metal zipper slider, eliminating stress risers from angled tool retraction surfaces.

Geared engagement and resilient locking slides enable quick attachment and detachment of carrying equipment without manual manipulation.

Segmented rod materials resolve sealing integrity versus opening difficulty by melting at the interface.
