Slide Fasteners TRIZ Cases

A track zipper uses a sliding core between tracks to connect components securely.

Rounded edges on the pull tab retainer recesses eliminate sharp metal corners that damage high-end pull tabs, preserving durability and finish.

Hollow areas in the tape enable mechanical interlocking with injected derlin material to prevent tooth detachment.

Rotatable slider pullers align multiple slider bodies on a fastener hub, simplifying operation for users with limited dexterity.

A layered molding process uses elastic material and fabric to create hollow three-dimensional objects.

Nested engagement secures the closure part to the slider body, preventing detachment and foreign object entrapment in the fastener gap.

Segmented zipper chains eliminate metal tooth waste and shipping costs by removing the need for separate gapping machines.

Integrated magnets and guide structures automatically position slider components, resolving manual alignment challenges for users with limited dexterity.

Segmenting the load-bearing connection system from the fluid-tight seal reduces force needed for user-friendly operation while maintaining reliability.

Curved rear end surfaces reduce sliding friction while ensuring reliable sealing at limit positions.

A zipper guide uses a slider key and base trench to align open-ended zipper ends via planar sliding.

Merging control plate functions reduces production costs while maintaining secure locking for zipper pulls.

A slide fastener box pin features a notched region with projecting suppressing portions to hold the second slider at an insert-pin position.
