Nuts TRIZ Cases

Cantilever lock blocks on a nut seat engage a bolt via a slide block, eliminating rotational access constraints under countertops.

A clip with elastic claw portions deforms to fit various hole shapes and returns to engage securely.

Segmented retaining device with outer flats fits through oblong holes to secure screws without modifying existing threaded components.

Thickened areas in the clamping ring balance mass moment of inertia while maintaining high connection torque.

Selective thickening reinforces anchor rails to improve stability while reducing material consumption in concrete.

Segmented repair tool extracts fractured bolts via guide bore, eliminating cylinder head removal.

A projecting shoulder on a vehicle trim base part supports an attachment component during clamping.

A low-alloy steel composition eliminates nickel to reduce costs while maintaining high tensile strength and toughness.

A reusable quick nut uses elastic tabs to adapt to varying panel thicknesses.

Segmented resin caps engage fasteners to maintain insulation gaps, reducing installation labor and manufacturing costs.

Circumferential cutters on the screw underside enable efficient countersinking while radial pockets receive material to prevent loosening in fibrous substrates.

A fastening element with alternating structural and free shaft sections enables rapid bayonet insertion into a receptacle.

Segmented fasteners enable remote pipe clamp operation without manual disengagement, reducing excavation size and maintenance costs.

Projections on a rotating tool trim excess sealant from fastener caps, eliminating manual smoothing steps and reducing production time.

Circular local force presses sheet metal into fastener undercuts, eliminating heavy press requirements.

A coaxial locking ring uses radially segmented detents to distribute unlocking forces symmetrically across multiple contact points.

A threaded connecting mechanism with a turning formation adjusts pole position during installation.

A clinch nut uses induction hardening to create distinct hardness zones, enabling secure fastening with high-strength steel members.

Segmented locking plates enable bidirectional disassembly in tight spaces by flexing the centre section to release torque.

Right trapezoidal conical thread profile generates radial compression force to prevent unthreading under shock loads.

A threaded rod locking device uses spring-biased plunger pieces within a tapered bore to automatically engage external threads upon insertion.

Segmented leg plates joined by a center tie increase contact area and bending resistance for high pull-out forces.

An intermediary frame distributes clamping forces away from the bore, preventing deformation while securing the trunnion.

Deformation sections on the shank create clamping force to stiffen spaced sections, reducing production effort and eliminating separate screw connections.
