Bolts TRIZ Cases

A nested locking element gives polyaxial bone anchors up to 35° pivoting while keeping bone plate assemblies low profile and pull-out resistant.

A coated composite guide pin improves fiber connector docking precision by resisting bending, corrosion, and wear while reducing insertion-end damage.

Angled recess facets improve driver engagement under high torque, reducing head stripping and easing removal of stripped fasteners.

Tapered recess surfaces improve stick fit, axial alignment, and torque transfer while staying compatible with standard straight-walled drivers.

A slit pin with a biasing engagement section adapts to workpiece tolerances, reducing pin repositioning while maintaining stable fixing.

Alternating full-height and short-height lugs cut excess hex head material while preserving torque transfer, axial stability, and standard tool fit.

A rigid bushing in the rubber flange absorbs fastener load, preventing over-compression and maintaining a durable conduit-to-case seal.

A detachable socket and hollow disk use a positioning mechanism to deliver specific torque in a compact, versatile fastening assembly.

Continuous tangent-arc involute surfaces keep bit and recess contact distributed under torque, reducing stress, coating damage, and bit fatigue.

Below-Ac1 annealing and 300-400°C austempering give cold-formed steel parts high tensile strength with improved hydrogen embrittlement resistance.

Orthogonal bolt-head channels and slots keep the tool aligned with the bolt axis, improving engagement and reducing slippage during rotation.

Interlocking cover panels frame a tank with a cohesive decorative scene while staying easy to remove, swap, store, and reconfigure.

A rolling tool removes the collar during thread forming, cutting a separate step while improving conical bolt insertion and holding values.

A vented receptacle and base create a pressure relief path in honeycomb composite inserts, keeping sealed overlays flat during flight.

Convex socket protrusions with inclined faces let this screw work with pluri-lobed, Torx, and hex wrenches while limiting deformation.

Angled spline bearing surfaces redirect contact forces inward to cut hoop stress, prevent dilation, and raise fastener torque life.

Interlocking projections on modular signage units speed alignment and mounting while maintaining a secure connection to the plate.

A movable diffuser changes limiter deformation so one fastening structure can seal and secure display panel parts across different gaps.

A conical tip over 40° with a ribbed shank and axial recesses enables direct wood insertion without splitting while improving pull-through resistance.

A conical frustum mold with main ribs, subribs, and a tapered punch guides metal flow to form precise Torx slots without burrs.

A compliance zone in expandable doweling legs enables uniform hole contact across stacked work pieces while avoiding damage and sticking.

An eccentric bolt head positions the pivot axis at the bore edge, creating tool-free furniture panel joints without gaps or pull-out.

A tapered lobular bit engages multiple fastener sizes while reducing cam-out, cutting driver changes, mis-installation, and waste.

Strategic slot geometry in an SPR collet holds short rivets in direction, preventing inversion and tearing without an O-ring.

A slotted hex socket with corner relief improves oxygen sensor access, increases travel, and applies torque directly with less effort.

Arc-shaped blades and a quarter-circle extension improve fastener fit, torque transfer, alignment, and damage reduction.

A tapered upper zone and vertical lower zone improve driver fit despite coatings, increasing torque contact while reducing cam-out and breakage.

An eccentric bolt and sleeve fasten racks or linear guides without post-drilling, cutting assembly time while tolerating hole misalignment.

Inclined ribs on a frustoconical punch guide metal flow to form precise Torx slots without burrs, reducing slippage and rework.

A rotatable cam pin locks and periodically tightens excavator bucket wear members without hammering, reducing service time and dislodgement risk.

Elastic ridged projections compress between a tube and mount to increase friction, prevent wobble, and maintain a secure fit.

An elastic S-shaped holder compensates for spoiler mounting tolerances to prevent play, improve alignment, and stabilize force transfer.

An enlarged hexalobular recess radius lets the tool seat deeper, reducing wobble and stripping while supporting higher torque during driving.

A stop sleeve and bolt extractor remove the bolt and sleeve together in one pull, cutting removal time and reducing component damage.

Angled distal flutes turn scraping into slicing, helping cannulated bone screws cut bone with less damage, fewer fragments, and lower insertion torque.

Grooved engagement areas let one plasterboard screw anchor accept slotted, Phillips, and TX blades while maintaining secure torque transfer.
