Snap Fasteners TRIZ Cases

A snap button uses inclined grooves on male and female parts to limit rotation during removal while allowing free movement during normal use.

Alternating thick and thin walls in the annular protrusion reduce mating force while maintaining detachment resistance, eliminating high precision requirements.

A hitch pin integrates a trigger mechanism to actuate retainers for single-handed operation.

Laterally stretchable substrates and magnetic layers enable sideway bending, eliminating curved groove molds.

Opposing dimples on interlocking profiles provide tactile feedback for sealing while colored lips solve identification issues in crowded storage.

A buckle uses a locking bar and counter locking bar to secure two parts together through simultaneous actuation.

A fastener system with asymmetric interlocking counterparts enables multiple connected configurations for precise fit.

A flexible connecting strip joins tent panels via sliding keder engagement, eliminating ladder use at the peak.

Replacing mechanical sewing with ultrasound welding reduces closure thickness and production time while maintaining fastening strength.

Universal dust shroud with adjustable collar accommodates varying grinder sizes to prevent bearing contamination and extend tool life.

Inclined spring tabs bias against a burner sleeve to displace the fastening point below the base surface, reducing Light Centre Length by 10 mm.
