Portable Lifting TRIZ Cases

Linked rotatable bodies form shaped cavities that reveal symbols through coordinated rotation.

Movable sheave slider system with multiple surfaces contacts ramp arm to distribute wear across segmented contact points.

A dynamic valve regulation method adjusts master cylinder flow based on real-time speed feedback to maintain consistent hydraulic fluid supply.

Offset tooth beams and dual gear wheels reduce weight and complexity while maintaining stability during slide out extension.

Dual motor belt system drives press brake rollers via serpentine path to increase pressure force per length.

Segmented limit guide and nested switch design resolve deformation risks while protecting components from external impacts.

A mobile winch system uses a segmented frame with wheels to transport motorized pulling equipment independently from vehicle power sources.

A frustoconical drum winch design reduces vertical dimension and motor torque through efficient cable winding geometry.

A variable length sling system uses pulleys and a worm drive to adjust rope length dynamically.

Motorized actuating assemblies prehend and translate storage housings to automate transfer operations, reducing manual labor in courier logistics.

A chain gripping assembly transfers load from a hoisting line to multiple clamps, eliminating excessive heat generation on the rope.

Segmented stopper doors pivot via gravity to hold a marine salvage chain in place while hydraulic pistons reset, preventing reverse movement.

Bolted teeth on a sprocket frame allow quick replacement of worn parts, reducing system downtime.
