Slide Fasteners TRIZ Cases

A black copper oxide coating with graded porosity covers a zinc-rich copper alloy fastener base material to resolve adhesion and color depth trade-offs.

Angled slide fastener elements engage at a non-planar angle to interlock heads and shoulders, preventing damage on curved surfaces.

A strapless nursing garment uses movable cups attached to an elastic band via zippers for one-handed operation.

Integrally formed slider guide plate with tapered sections and chamfers guides coupling elements, reducing misalignment and deformation of sealing lips.

Merging multiple weft yarn functions into one continuous thread eliminates thickness increases while maintaining attachment strength for thin, smooth designs.

A slide fastener slider uses localized stopping elements to increase sliding resistance and hold position.

Controlled aluminum alloy composition reduces cracking during slider manufacturing while maintaining lightweight structural integrity.

Recessed coupling element surfaces protect embedded decorations from wear and trap errant plastic fibers during manufacturing.

A releasable coupling device uses magnetic attraction between temporary and permanent magnets to join slide fastener housing structures.

An intersecting pin surface guides separable pins away from retainers when a slider moves down, resolving removal jams.

A slider uses a rotating cover to press a swing tab into or out of the element guide path for locking.

A slider fastener design separates the control claw from the cover to optimize component rigidity independently.

Integrating the spring onto the pull tab shaft reduces slider volume while enabling automatic assembly of the fastener component.

An integrated biasing member biases a locking prong into zip teeth engagement, eliminating complex assembly steps while securing detachable pull tabs.

Two intersecting zip fasteners expand the gripping area while maintaining reliable closure and preventing object loss.

An inorganic binder with aluminum pigment maintains torque resistance at 900 degrees Fahrenheit, preventing bolt loosening in gas turbine engines.

Parallel knitting device produces multiple stringers simultaneously, eliminating post-processing complexity from single-stringer conveyance.

A separable pin accommodation part restricts pin position between walls to enable easier rotation during fastener opening.
