Nuts TRIZ Cases

Silicate sealing on phosphated screws creates a dry lubricating film that eliminates oil residue contamination in automotive assembly systems.

Asymmetric thread profiles abut continuously to eliminate backlash without adding complex compensation mechanisms.

An asymmetric nut holder places spring legs on only one side, allowing large axial deflection and secure clamping without increasing overall height.

Welded connecting device secures a metal guard over threaded stems, preventing accidental impact damage to nearby fuel tanks during vehicle collisions.

Alternating radial protrusions on the insert flange engage counter bore features to prevent over-rotation and thread stripping in blow molded plastic parts.

An extrusion plunger presses hardenable compound from a reservoir between the shaft and borehole wall, eliminating separate dosing steps.

A deep-drawn locknut uses a locally deformed internal thread bead to generate braking torque without external adhesives.

Varying wall thickness in the internal threaded portion distributes tensile force effectively, preventing deformation while reducing weight and material cost.

Spring members in the support structure accommodate varying anchoring member thicknesses and tolerances while maintaining stable clamping force.

A welded receiver shoulder creates a fixed gap to control seal compression between flanges.

A threaded insert anchor restores stripped screw holes in door frames using a double open-ended hollow cylinder with external and internal threads.

A threaded pin with a smaller bore diameter generates friction torque to lock screw elements without external tools.

Galvanic transition metal coating with lubricating top coat prevents eggshell effect while improving drilling performance and heat dissipation.

A dual locking barrel nut system secures free float tubular handguards to bolt action rifles.

Metallic glass inserts resolve galvanic corrosion risks in heritage material joints while maintaining high elastic strain limits.

Aluminum oxide gang channel with silicon carbide whiskers provides high strength and thermal emissivity.

Recessed closure units prevent wear and unauthorized loosening in agitator mill bores via chilled installation.

A conductive ring nested in a raised edge passage deforms under bolt pressure to expand contact area.

A piston spring retainer uses a rod-shaped member fixed within a concave portion to restrict spring length and prevent loosening.

Multi-stage cold forming produces housing rings from wire bundles, eliminating mechanical machining complexity.

A deformable cap nut portion enables angular adjustment of a fuel injector sensor connection point during assembly.

Inner formwork holding units guide concrete anchors through pre-drilled bores for secure placement during casting.

Segmented shells with replaceable bristles reduce downtime by allowing partial roll replacement instead of swapping the full unit.

A threaded fastener assembly with a recessed boss attaches overlapping aircraft components while maintaining an aerodynamic surface finish.

Elastic elements apply torque to keep the insert plate spaced from the branch, enabling single-gesture installation without complex alignment gestures.

Radial expansion of the tubular body via a mandrel eliminates the need for multiple bracket sizes while enhancing fatigue performance.

Bent tabs on a metallic retainer cage engage hexagonal nuts and lock via safety wire tension, preventing unthreading under vibration.

Segmented covers with universal fastening parts resolve the trade-off between assembly efficiency and manufacturing precision in battery packs.

Embedding anchors in the form eliminates post-cure drilling, preserving structural integrity and reducing installation time.

Deformable sleeve buckles and expands radially to form an upset head, preventing cracks and delamination in composite materials.

Segmented helical threads with increasing major diameters prevent unintended loosening in cleaning tools by enhancing connection stability.
