Slide Fasteners TRIZ Cases

Breach holes and retaining blocks in the cap body secure the elastic piece, resolving insufficient retention while maintaining simple device complexity.

Twisted projections on the monofilament surface diffuse light to reduce luster while maintaining structural strength.

A length-adjustable support assembly uses a lock stop and peg array to secure a support bar within a travel track.

Dual sliders on a vertical fly enable seated urination without removing belts or causing chafing.

Segmented retaining body and elastic component improve positioning precision of invisible zipper sliding member without increasing structural complexity.

Segmented interlocking zipper pull tabs prevent snagging while requiring multiple movements to open zipped compartments.

A zipper head assembly uses a guiding member to create a receiving space for a replaceable pull tab.

Tapered synthetic resin fastener elements with constricted necks replicate metal aesthetics without increasing weight, preventing chain breaking during bending.

A zipper slider employs a cam mechanism to force pull tab rebound, preventing loosening after closure.

Selective tape adhesion maintains element row flexibility while achieving environmental compliance.

Notched resilient profiles evacuate air while blocking liquid ingress, ensuring reliable vacuum sealing without thermal apparatus.

Clearance recesses on the slider upper blade create non-contact regions that reduce pull fixation and marking during coating.

A slider guide pillar features a first groove and blade gap to manage fastener tape passage.

A fastener chain sandwiches attached bodies between element spaces to enhance holding force.

Segmented recesses on fastener elements contain ink droplets to prevent spreading and ensure clear contour definition.

Guide grooves orient concealed slider elements to prevent nipping under lateral pulling force.

Stamped metal zipper teeth feature a five-plane retaining hole structure that securely clamps onto the zipper tape rib.

A stretchable fastener stringer uses a specific coupling head bulging ratio to maintain element engagement during tape expansion.

Segmented compartments isolate shoes and umbrellas from electronics, preventing soil contamination while maintaining organized carrying capacity.

Layered beta-phase grains in a copper-zinc alloy suppress season cracking while maintaining cold workability.

Folded closing tapes overlap the meshed area of a self-sealing fastener to block liquids and particulates in protective apparel.

Dynamic cavity walls enable single-operation formation of metal slides, removing stress risers from internal angles and improving durability.

Side shifting mold sections retract independently to clear complex geometries, eliminating stress risers from internal angled surfaces.

Male base replaces cloth brim to slide against female teeth, reducing total friction and noise while improving sealing performance.

Segmented pull tab attachment with base and wall portions guides string members, preventing breakage during operation.

A slide fastener tape uses distinct regions to interpose a flexible member flap, simplifying the sewing process.

Segmented net panels coupled by a zipper interface transition between deployed and folded states to resolve time loss during article retrieval.

Projecting inner longitudinal edge portions overlap in the closed state to eliminate visible gaps and achieve a water-tight seal under tensile stress.

Nested pocket design with aligned zippers allows rapid beacon retrieval, eliminating time lost undressing during avalanche emergencies.

A cover attachment structure uses a recessed groove to lock fastener elements for secure mounting.

A slider closing member covers the upper blade fixing portion to unify the pull tab appearance.

A child resistant slider uses a flexible tab and torpedo to separate interlocking zipper profiles.
