Nuts TRIZ Cases

A fastener assembly uses a deflectable lock member with ratchet teeth to secure threaded connections against loosening.

A mounting rail system prevents corrosion damage to bus body coatings while allowing flexible repositioning of interior equipment components.

A self-tapping insert with a detachable pilot guides alignment during installation, eliminating the need for magnetic drills and reducing shattering risks.

A waterborne coating composition combines fluoropolymer particles with a phenoxy resin binder matrix to form a durable protective film on metal surfaces.

Vapour deposition creates a multi-layered coating on threaded fasteners, eliminating deformation and corrosion while maintaining anti-seize performance.

A hygienic screw design uses a conical section and integrated O-ring seal to create a smooth, gap-free interface between the fastener head and housing surfaces.

Rotating retaining frames parallel to the clip leg decouples width from fastening dimensions.

Segmented knurls with varying tooth densities coordinate material flow to resolve insufficient rotational load capacity in hard workpieces.

A hollow stainless steel screw design reduces mass by removing the solid core while maintaining thread integrity.

A double thread screw uses a smaller diameter section with concavities to cut debris.

Segmented bendable tabs on a dual lock washer prevent fastener rotation under extreme conditions without increasing device complexity.

Torque clip prevents nut jamming and rattling noise by defining minimum offset distance without welding.

A surmoulded threaded insert uses a fusible zone to adjust axial length under compressive force.

Tangential wire coils with inverted finger grip limbs allow one-handed operation, resolving the trade-off between locking reliability and manual effort.

A push-and-turn nut uses an insert with downward projections that expand outward to secure a tailpiece upon axial pressure.

Elastic tongues in a U-shaped cage lock a screw head, enabling tool-free panel assembly and disassembly.

A gangable composite deck clip joins dissimilar materials through a bonded T-shaped structure for secure attachment.

A reusable threaded fastener uses a hollow lock bolt and tapered stud to create redundant locking features.

A vehicle roof clip uses flexible wings and a double base to reduce insertion force while maintaining stable fastening.

Axially movable threaded piece in a holder compensates for component tolerances to reduce mechanical stresses during electric machine assembly.

Segmented spring arms allow separate manufacturing of bearing and sliding parts, reducing assembly complexity while maintaining stability.

Preheating fasteners enables molten adhesive plastic to bond securely, preventing rotation and eliminating debris from brittle or loose collations.

Integrated molded slots expand to lock screw shanks, eliminating metal standoffs and reducing manufacturing complexity while maintaining EMI shielding.

Dual sealing rings on a single plastic cap prevent paint ingress during cathodic dip painting, maintaining thread integrity despite sheet metal deformation.

Modified Acme screw and nut set with increased radial and axial clearances to accommodate thermal expansion differences between steel and nylon components.

A flush screw fixing structure secures a substrate to a supporting plate without protruding components.

Multi-diameter holes in a single planar clip eliminate adapters and reduce injury risk from sharp edges.

Oversized elastic collar deforms through opening to lock socket, eliminating slot accessibility needs and simplifying assembly.

Axial wrench flat arrangement on screw fittings resolves tight installation space constraints by allowing larger tool engagement without increasing unit volume.
