Washers TRIZ Cases

A blind fastener device uses a segmented sleeve and expander to expand and lock via relative rotation.

Crowned lock nuts enable simultaneous two-directional alignment of a cylindrical sensor section, reducing adjustment time.

A split stop ring assembly uses retaining means to hold half-rings together during installation on a shaft.

Nested cylindrical members capture a resilient member in specific receiving volumes to prevent shifting under load, ensuring uplift resistance.

Elastic deformation in the clamping member accommodates mounting misalignment, eliminating clearance and preventing vibration loosening.

A load-indicating washer uses a collapsible domed cap to mechanically signal clamp-up force thresholds through plastic deformation.

Segmented O-rings and recesses in a main washer create metal-to-metal and fastener seals, resolving sealing issues in large clearance holes.

A segmented washer design absorbs reaction forces and constrains axial movement to control bolt elongation during tightening.

Anchors embed flush with concrete slurry using a specialized float design.

Coaxially stacked fastener caps connect via shearable stems to eliminate manual assembly and allow easy reinsertion into nailer magazines.

A fastening device uses a slot-shaped spacer sleeve and damping elements to connect aircraft components securely.

Internal fastener assemblies adjust wear plate height while protecting mechanisms from harsh environments.

A 3-in-1 fastening system integrates a metal washer, rubber seal, and retaining element to secure mill liners.

Segmentation replaces complex resilient fingers with standard threaded elements, lowering manufacturing costs while maintaining high connecting strength.

A spacer assembly with a flexible bumper support compensates for manufacturing tolerances.

Segmented ring angles in a locking washer generate vertical force to press the outer edge into the base, preventing loosening under high tightening forces.

An overmolded gasket on the washer prevents water intrusion and corrosion in traction battery packs without compromising seal integrity.
