Snap Fasteners TRIZ Cases

A clip uses flexible strip members to lock into a through hole for secure attachment.

A polymeric base fastener with a laterally sliding metallic retainer accommodates body panel variations while maintaining high retention force.

Integrating a tear line into the zipper flange using peel seal resin eliminates separate opening components while maintaining package hermeticity.

Sliding lobes engage bracket slots to eliminate high-torque assembly and reduce weight in vehicle hydraulic unit installations.

A magnetic connector uses a bull-nose male end and female hook trap for secure engagement.

A device clip engages a spring-loaded rod into a locking groove to maintain stable binding force, replacing degrading Velcro tape on camera bags.

Profile strips with transverse locking elements create sealed flow channels between bundles, preventing contamination during lateral docking.

A synthetic resin mounting plate couples with a metal bracket clip to secure automotive side airbags.

Segmented apparel pocket with releasable upper panel exposes weapon storage area, reducing deployment time while maintaining concealment.

A buckle uses a folding-back shaft to adjust band length.

Segmented ribs distribute load through apertures to prevent sink marks on the exterior surface.

A reclosable slider uses a rigid core and soft ends to engage tracks while conforming to film surfaces.

Deformable gripper tabs engage external hollow ribs to resolve installation complexity and versatility constraints in metal decking assemblies.

A fastener with a bulk amorphous alloy interlock portion forms a permanent mechanical bond during installation.

Segmented components and preliminary spring action enable rapid strap replacement without specialized tools.

A rotatable fastener with a cylindrical body and keyway configuration secures trim components to sheet metal structures.

A two-piece clamping element uses a pivot bearing to articulate opposing jaws for rod-shaped elements.

A mechanical-magnetic connection structure uses lateral magnet displacement to release a spring locking piece for easy opening.

Snap-fit attachment devices secure crown molding to walls using flexible elastic portions, reducing installation time and labor costs.

A press-fit button actuates a lock hook to secure medical apparatuses on a base platform.

Segmented button caps rotate into attachment bodies, enabling user customization without disassembly.

Tapered bore geometry creates controlled friction to maintain suture tension and prevent disassociation under cyclic tissue stress.

Segmented wedge openings and a sliding support surface eliminate knot-tying complexity while providing mechanical advantage for rope tensioning.

A belt lock uses a rail and groove with interlocking recess and protrusion sections to secure the attachment firmly.

A seat latching system uses a biasing member to assist latch arm movement between positions.

Radial truss structures and rounded serrations resolve tensile strength versus breakage trade-offs in button head ties.

A clamping collar uses a pushed-in outer belt portion to form an external tightening wall for secure pipe engagement.

Integrating a key-operated lock prevents inadvertent strap release during transport while enabling compact storage when the handle is removed.

A quick release apparatus connects an SCBA frame to a waist belt via pullable rapid release members.

Pre-assembled clip and retaining element resolve structural integrity issues during panel insertion, enabling efficient assembly in confined spaces.

A two-part fuel injector clamp uses offset passageways and dual bolts to distribute clamping force evenly across the assembly.

A mat lock pin rotor carries axial forces through angled surfaces to compress overlapping mats.

A strap button uses an outer flange and retaining flange to secure instrument straps.

Molding a transverse pin through a folded flat bungee cord end eliminates bulky traditional terminus designs that distort thin cords and slip under load.

A hinged bushing suspension clamp simplifies aerial cable installation by allowing independent half placement and secure fastening.

A single-piece clip attaches a protective member to a vehicle support using resilient pawls and a tapered tube, eliminating the need for mounting holes.
