Rivets TRIZ Cases

A telescopic shaft collapses and re-expands the radial lock, letting metal deck anchors be secured, removed, and repositioned from the topside.

An internal screw-driven clamping member lets a blind fastener fit 2-4 mm apertures while providing reliable clamping and easy removal.

Sliding grooved hooks and elastic clamps let one temporary fastener securely assemble structures across a wide thickness range without added length.

Grooved self-piercing rivets guide radial material flow to improve thread filling, maintain holding force, and allow reversible removal.

A tolerance-and-stop pin lets an elastic hook pass an attaching hole, then lock firmly in one push while maintaining a sealed attachment.

A guide-groove pin lets this clip switch between temporary and permanent fixing while improving tolerance for hole size and plate thickness.

A soft compression sleeve expands in a hard panel hole to lock a threaded insert by friction, avoiding adhesives, welding, and cure time.

A press-fit securing sleeve joins the bush, disc, and dragging element to improve force transmission and simplify tolerance compensation assembly.

Sectional gripping fingers create a two-part anti-rotation and translation stop that resists torque loads without limiting collet extension.

Inward slug-securing ribs hold the punched slug inside a self-punching fastener cavity, preventing loose-part damage and slug removal steps.

An angled collar end and concave radius increase contact area, cutting installation force, bearing stress, and coating damage.

Limiting blind fastener pull-region length reduces installation force while maintaining secure swaging, mandrel strength, and tool life.

A recessed rotation stop and annular groove guide plate metal during press-fit, preventing burrs and warpage while maintaining detachment load.

An insulating washer and sealed air cavity let blind fasteners clamp securely without stripping paint, reducing arcing risk.

Angled undercut walls and an annular locking space let a self-piercing fastener resist pull-out, press-out, and torque in sheet metal.

A lateral opening and stop mechanism lets temporary fasteners use more thick elastic clips, increasing grip area across wider structural thicknesses.

Conductive contact layers route lightning current between composite members to suppress fastener current concentration and spark generation.

Selective strain hardening creates a one-piece sleeve nut that prevents nut-sleeve slippage and eases blind fastener removal in tight spaces.

An internal locking lug and sleeve recess fix button orientation, enabling precise detent bolt alignment and reliable locking.

A shaft removal region captures top-layer material before friction welding, keeping the joint zone pure and improving layer-to-layer connection reliability.

Finger-based anti-rotation in a single-sided collet fastener resists high torque and prevents over-translation during blind-side installation.

A bonded pin and swaged collar fasten two components while eliminating one hole, improving placement freedom and vibration resistance.

A deformable collar locks onto a smooth shank to avoid cross-threading, simplify multi-layer fastening, and maintain joint strength.

A hollow self-piercing rivet with an internal insert improves flaring in AHSS and UHSS, reducing stress, cracking, and weak interlock.

One-time upset extrusion forms self-clinching rivets without machining waste, while preserving metal flow for consistent dimensions and higher strength.

A removable core directs workpiece material into an accommodation space, improving rivet sealing and interlocking without penetration.

Flexible panel and stud retention fingers replace interference bumps to cut installation effort while increasing extraction force.

A tapered self-piercing rivet cuts a slug from UHSS, then locks into a softer sheet to avoid shank collapse and improve joint sealing.

Adjustable opposing hooks replace screws or plugs, speeding plate assembly and disassembly while maintaining a stable connection.

Mechanical grip features lock a blind fastener to its tool for reliable robotic installation and extraction without misalignment or drop-off.

Cold rolling forms adjacent ball sections and connecting sections from one cylindrical blank, cutting welding steps, time, and waste.

A breakaway pin-and-plate fastener pierces stacked sheets and deforms to lock metal and fiber-reinforced parts with simpler handling.

Cold forming a cylindrical blank between rolling tools creates adjacent ball sections in one step, cutting welding, waste, and cycle time.

A movable tubular sheath insulates the bolt and sleeve after installation, blocking lightning-induced arcing in composite aircraft structures.

A plug-nut pile connector cuts aperture alignment time, uses less material, and keeps bolt threads out of the shear plane.

A fracture-pin and plate joining part pierces stacked sheets, improves alignment, and creates a rotationally secure connection in fiber-reinforced plastics.

A tapered hollow rivet section lets the punching slug pass through the threaded cylinder, avoiding a trailing punch while preserving joint strength.

Softening the opening edge and forming it with a mandrel aligns joined holes precisely while avoiding fiber damage and contamination.

An angled swaging surface controls rivet head deformation to avoid hole clearance and preserve fatigue strength in fastened joints.

A replaceable-tip drill bit combines drilling and fastening in one tool, using spiral chip grooves and a deformable locking section to cut time.

A free-spin zone decouples the drive tool from the collet screw, preventing blind fastener disassociation and damage during removal.

Inclined ramp fingers align and seat a lockbolt collar flush before swaging, improving fastener installation in low clearance spaces.

A spring-biased collet fastener reduces lateral play and work piece rotation by converging flexible fingers for stable temporary clamping.

A sacrificial polymer ring releases oil during insertion, cutting force and protecting multi-layer aircraft holes from fastener wear and damage.

A deformable sleeve compressed by a core pin forms a flared blind-side joint, securing workpieces where rear access is unavailable.

A free-spin zone decouples the drive tool from a blind side fastener, preserving collet integrity and preventing damage during removal.

Over-molded mechanical interlocks join dissimilar substrates through apertures, cutting assembly labor while improving stress distribution and weight.

An interference-fit lock region retains the collar on the pin without threads or elastomers, cutting fastening time and cost.

Movable support elements spread to match complex workpiece geometry, enabling secure fastening and forming without deforming soft sections.

An integrated reshaping element deforms the rivet radially during insertion, removing the separate die and improving fastening in thin components.
