Haberdashery TRIZ Cases
- Hook-to-Hook Fastener With Sealing Ribs
A hook-to-hook fastener integrates longitudinal ribs alongside hooks to create a tight mechanical seal between mating surfaces.
- Snug-Fit Horse Rug Closure System Resists Snagging
A horse rug closure system uses a shaped connector to sit snugly against the chest.
- Wire-Gate Carabiner Torsional Biasing and Debris Shielding
Torsional gate biasing and lateral shielding prevent debris obstruction while reducing weight.
- Hemostatic Clip Material Design for Reusable Ligation
A hemostatic clip uses a metallic material with a wider elastic deformation range to maintain opening width during repeated pinching.
- Karabiner Hook with Integrated Blocking Element
A karabiner hook integrates a blocking element on the closure part for one-handed operation.
- Wire Lever Carabiner Bulb Coupling Rope Interference
A wire lever carabiner uses a bulb-shaped coupling portion to secure the spring closing member against accidental opening.
- Fastening Tape Membrane Foam Attachment
Segmented membrane pockets allow foam curing to create mechanical interlocking, resolving weak direct bonding interfaces.
- Actuated Velcro Fasteners with Shape Memory Alloys
Moveable features on a substrate change shape using bimetallic coils or shape memory alloys to engage loops for automatic bonding.
- Detachable Pet Toy With Adjustable Hook-and-Loop Resistance
Hook-and-loop fastening surfaces on a detachable pet toy provide adjustable resistance and clear progress indication for satisfying tug-of-war games.
- Surface Functionalization of Adhesive Fastener Parts
Adhesive fastener parts receive surface energy modification via high-energy radiation and proton exchange media to attach functional groups without coatings.
- Anti-skid Chain Deflection Roller with Eccentric Pawl
An eccentric pawl engages a ring gear to block rotation while minimizing unlocking force, avoiding complex multi-pawl designs.
- 3D Burr Fastener with Flexible Joints for Complex Structures
Three-dimensional burr fastener uses flexible joints between heads and stems to resolve alignment issues in concrete reinforcement assembly.
- Molded Male Surface Fastener Positioning Accuracy
Optimized D/H ratio and plate coverage prevent unnecessary engagement during temporary positioning while maintaining strong attachment force.
- Self-adjusting bar clamp toggle mechanism
Toggle mechanism overcomes grip strength limits by using a ratchet to accumulate force for secure workpiece holding.
- Molded Hook and Loop Fastener with Segmented Flexibility
Segmented hook and loop fastener parts connect via flexible members to enable bending at larger curvatures.
- Cord Length Adjustment Device with Notched Walls
Notched walls constrain resistance bands to prevent disengagement, eliminating the need for multiple specialized bands.
- Surface Fastener Head Area Optimization for Peel Strength
Optimizing engaging head areas to 22000-50000 μm² resolves the contradiction between peel strength and dimensional constraints in surface fasteners.
- Angled Fastener Fields for Panel Tension and Shear Resistance
Segmented fastening elements with angled directions prevent premature engagement while resisting cross-shear loads.
