Buckles TRIZ Cases

A belt buckle fastening component integrates an elastic prestressing element to simplify assembly.

Offset magnets pull latch hooks into engagement, eliminating moving parts that wear out and requiring high dexterity.

An eccentric metal locking unit rotates to constrain a strap, resolving the trade-off between manufacturing cost and structural reliability.

Anti-skid buckle ribs prevent webbing deflection, reducing skin scratches.

An extension piece on a buckle body presses webbing against the fastening cavity, preventing pet hair or skin entrapment during engagement.

Segmented tongue mechanisms with biasing sliders clamp webbing during impact while maintaining slim profiles for occupant comfort.

Integrating a striker and beam into a strap buckle generates sparks for emergency ignition, eliminating separate gear bulk.

A stainless steel latch set uses angled slots and inward tabs to secure spa cover straps without cutting the material.

An adjustable control clip cinches webbing securely using a tri-bar adjuster and hinging mechanisms.

A retainer element prevents cable protrusion into the buckle housing, eliminating costly component rework.

A seatbelt buckle uses a blocking member to split the latch plate slot into two portions, preventing debris entry while maintaining operation.

A strap assembly uses a rotatable locking member to trap the strap body against an adjustment clip base.

Segmenting the buckle into fixed and removable parts enables cross-bar replacement without cutting attached webbing.

A strap releasing control mechanism integrates a press key and slide key within a single shell to adjust leash length.

Rotating convex portions in a belt buckle generate strong frictional fixation, preventing unintentional loosening under external forces.

A magnetic buckle assembly uses embedded magnets and slanted surfaces to lock two portions together securely.

A double locking buckle uses a plug member with lock arms and a socket guide groove for secure coupling.

A webbing adjusting buckle uses a roller and elastic limit locking member to enable safe length adjustment.

Translation of movable plate grips strap firmly, preventing slippage without complex hooks or aesthetic holes.

A belt fastener uses arcuate arm members to apply biasing force between movable body portions for secure strap retention.

Stamped buckle assembly replaces forging to prevent cracks, using segmented components for reliable locking.

A segmented seatbelt buckle cover uses removable sections to create a secure, heat-resistant barrier over the handle and latch.

A tethered strap keeper restrains loose strap ends near the adjuster frame, preventing slippage and maintaining safety during component failure.

A spring-loaded buckle assembly with a pull ring and actuation button enables secure cord attachment through simple mechanical engagement.

A female buckle body retains male extensions and retainer rings via a pivoting lever, eliminating the need for separate components.

A C-shaped assistive device uses a lever arm to compress car seat buckles with minimal finger strength.

An integrated fastening unit pivots on shaft seats to adjust strap length, eliminating separate rings that increase weight and cause safety hazards.

Spaced apertures on the buckle supporting member engage a spring contacting the structural frame, resisting deflection and reducing unwanted noise.

Sequential actuation of a sliding element and release button prevents accidental disengagement while maintaining reliable fastening for wearable devices.

Segmented guide surfaces on socket plates correct oblique plug insertion to improve alignment reliability.

A positioning shim separates superposed buckle rings to reduce friction, enabling easier strap adjustment without increasing device dimensions.

A belt fitting uses a cambered clamping contour to distribute force across the webbing width.

Preconfigured inlays mount to a recessed frame via rivets, resolving dimensional mismatch risks from piecemeal customization.

Magnetic attraction joins buckle components while a hinge enables 360 rotation, solving weak connection limits.

A webbing securement device uses a spring-loaded wedge and pivot rods to clamp flexible restraint material.

A racing seat belt buckle lever rotates to release tabs while its contoured profile prevents accidental rotation.

A multi-point buckle uses a dust jacket with a loop lip to seal the gap between the tongue and slot.

Merges the cover and operating element into one component, eliminating external linkages to reduce buckle weight while ensuring simultaneous release.

A rotatable cam cover clamps seatbelt webbing between a locking surface and itself to secure the restraint.

Segmenting the buckle into a universal base and interchangeable inserts resolves the trade-off between design variety and purchasing multiple complete units.

Segmenting the inertia member into two levers applies directional pressing forces to block unintended release while allowing intentional operation.

A buckle uses a spring gate in a guide track to lock straps securely without deforming the locking element.

Symmetrical ring buckle uses pull-string release to stack diverse belt ends, solving versatility limits in fastener design.

Thickened base portions and angled latch surfaces prevent separation under pull loads while allowing easy detachment via minimal arm distortion.

Angled side fasteners engage an adjustable strap to retain length, preventing damage from concentrated stress points.

Extension guard buttons secure chest clip position to prevent downward movement and maintain proper child restraint.

A buckle part integrates a coaxial hanging eyelet to attach carabiners while maintaining structural integrity.

Elastic locking segments engage a retaining segment to withstand tensile forces while allowing easy manual release.

A quick release buckle uses elastic legs and a pulling member to enable single-step disassembly.

Segmented seatbelt tongue with sliding latch plate reduces occupant chest load during collisions by absorbing impact energy.
