Nuts TRIZ Cases

Flush rubber sandwich and spring pin retention keeps mining chain drive pins from shearing or sliding out under lateral forces.

Abraded solid low-melting alloy particles coat CFRP hole surfaces to improve fastener conductivity and make interference fit more repeatable.

Flexible wall portions and spring members keep channel fasteners engaged with flanges at a consistent holding force despite anchor thickness tolerances.

A sliding keeper aligns locking teeth without rotating the nut, preserving bearing torque while securing the lock nut on the shaft.

By countersinking a floating nut into the plate, this case improves blindside clearance, tolerates misalignment, and reduces fouling risk.

An asymmetric micro-thread profile creates continuous helical edge contact to resist vibration loosening without glue or extreme machining precision.

Head ribs and tapered shank geometry limit over-tightening and reduce torsional breakage while maintaining secure thread engagement in substrates.

Orienting contours let a hammer head fastener enter an undercut groove from any rotary position, speeding mounting and secure fixation.

A pre-formed shaft curvature guides bead formation to a fixed setting location, improving clamping force and rotational strength in brittle or thick materials.

A retaining ring that rotates both ways lets lock nut teeth align without extra nut rotation, preserving wheel end torque or preload.

A threaded locking unit with meshing securing elements stops motor rotation in pool cleaning robots while simplifying assembly and repair.

A threaded base and attachment element with a bracing securing element adapts to insulation thickness while locking length against rotation.

A flange-and-protrusion joining member aligns and rivets a steel body to a lightweight damper housing while limiting galvanic corrosion.

A soft sleeve deforms around a hard threaded insert in a blind hole, preventing torque-out and pull-out without adhesives or heat.

Convex thread portions and an inclined end face improve chip discharge and foreign matter removal to prevent jamming and lower driving torque.

Concrete screws in undersized boreholes with waterproof adhesive give guardrail posts immediate resilience while sealing out moisture and easing repair.

A spacer and cap screw mechanically retain a carbide valve plug tip, avoiding brazed or shrink-fit stress risers that cause erosion and vibration cracks.

Heating thermoplastic composite parts lets threaded fasteners displace fibers instead of cutting them, improving joint strength and assembly efficiency.

A multi-point aperture and circumferential slot stop bolt rotation under vibration by increasing static friction in the mount assembly.

A guided jaw assembly locks only after sufficient rod insertion, improving concrete anchor alignment and full thread engagement.

Paired retaining projections lock into mounting slots to connect rails flexibly while resisting rotation and improving fastening stability.

Local thread-height control cuts transitional thread length to about a quarter turn while preserving alignment and engagement with female threads.

Resin insulation keeps a floating case nut from sticking during electrodeposition coating, preserving axial deviation absorption and fastening workability.

A point-contact thread profile resists vibration without coatings or pins, while allowing large-diameter fasteners to spin freely and be reused.

A metallic grounding member links CFRP rib panels and wing fittings to dissipate lightning current without losing weight or thermal fatigue benefits.

A multi-grip wing bolt head cuts tool variety and speeds external bone fixation assembly in urgent trauma settings.

Conical olive-like threads improve bolt-nut self-positioning, locking force, and anti-loosening stability under vibration.

A spring-biased handle and rivet nut receptacle keep quarter-turn panel fasteners secure without back-side access or handle dislodgment.

Grooved guide rails and an alignment key position switch assemblies accurately on conveyor frames while avoiding spreader interference and damage.

An asymmetric dumbbell-shaped internal thread improves self-positioning, joint strength, and anti-loosening under vibration and temperature changes.

A tapered three-lobe driver fits multiple fastener sizes to improve alignment, cut cam-out, and maintain reliable torque transfer.

Adjustable threaded connectors and a friction pin eliminate excess bolt length while giving through-bolted joints a cleaner architectural finish.
