Shackles TRIZ Cases

A non-linear entry channel and locking keyhole secure a clevis pin without tools while preventing unintentional removal.

Internal locking and twin pins secure multiple fall arrest devices while preserving pivot freedom and easy harness attachment.

A composite collector chain with stepped pins and stress sensing cuts corrosion, debris buildup, power use, and maintenance in settling basins.

A bolt-locked mooring link enables subsea coupling and release while fitting chain wheel pockets and resisting unintentional opening.

Interrupted reinforcing ribs let rope sling shackle arc flanks deform under oblique loads, reducing added stress while preserving stiffness.

A grooved locking pin and key-operated lock replace welded retainers, speeding dragline rigging assembly while reducing damage and downtime.

A spring-tuned actuating line and snap shackle deliver repeatable preset load release without frangible parts, extra weight, or replacement.

Embedded magnets replace threads to create quick, fluid-tight hose connections with less hand strength and less jamming from debris or temperature.

Unequal rope-branch lengths cut link-structure load and keep connectors in place for easier, lighter rope connections.

Axial push engagement lets a shackle pin lock quickly without manual threading, improving secure assembly in hazardous rigging conditions.

Repulsive magnetic poles and a post-guiding groove lock heavy-object fasteners in place while still allowing easy assembly and disassembly.

A shackle-mounted blocker prevents karabiners from clipping to the wrong opening, forcing attachment to the lifeline end connector.

Synthetic fiber rope loops replace rigid metal bows to cut shackle weight while preserving load strength, flexibility, and corrosion resistance.

A dual-release mooring mechanism combines acoustic hydraulic actuation, mechanical backup disconnect, and sensor telemetry for subsea reliability.

A spring-loaded safety pin adds rotation to axial motion, making chain link insertion and removal easier while maintaining secure locking.

Pivoting levers form separate connection and removal spaces, letting one tool join or separate roller chain master links without extra pliers.

A bolt-secured chain sling connector forms loops without hook-induced bending stress, preserving load capacity and preventing loosening.

A segmented long-hole closing plate secures the chain pin under vibration and high load while preserving narrow bicycle chain geometry.

A rotating link with a spring-loaded pin enables secure, tool-free band length adjustment without the skilled handling required by removable links.

Geometric interference and elastic chain loops create a self-locking chain connector that cuts parts, cost, and loosening risk.
