Metal-Working Hand Tools TRIZ Cases

A puller synchronizes claw movement via a receiving portion to ensure secure engagement during operation.

Bracing dogs distribute torque against rotation direction, preventing cheater bar slippage and user injury during high-force operations.

A seat insert tool uses a dual keyway jaw on a threaded rod to grip and rotate valve components.

Hydraulic actuators apply high magnitude forces to remove bushings, resolving the trade-off between removal speed and device complexity.

A segmented tool handle uses a threaded fastener with a conical abutting portion to secure tube segments.

A blunt expanding wedge with stop shoulders controls clamping sleeve expansion through gradual force distribution.

A cam-actuated release system enables rapid tool interchangeability while maintaining stable rotational and axial constraints during surgery.

A tool handle extension uses a central bore and side slot to grip various wrenches.

Radial conduit connectors reduce axial space demands for series-connected hydraulic screw tensioners.

A hot stick tool connector uses a spring-loaded cam to rotate accessory tools without manual nut handling.

Symmetric piston alignment eliminates moment loads and tool wear while enabling versatile pressing of various fitting sizes within a safe enclosed housing.

A multi-legged collet expands via a wedge element to grip annular carbon face seals for extraction.

A sleeve-component extracting jig uses a tapered helical thread to engage internal surfaces without damaging surrounding structures.

A single electric motor drives mechanical and hydraulic subsystems to deliver adjustable axial displacement for rivet nut installation.

A press tool applies a fixing element to constrain jaw movement, preventing uneven deformation and burr formation on press fittings.

An elongated rod with a sliding lever compresses valve springs in place, eliminating user obstruction and avoiding full engine removal.

Rotatable key mechanism provides mechanical advantage to tighten chains, reducing manual effort during cold weather installation.

Lever actuation moves a pusher along a hollow tube to mount rings, preventing deformation from uneven force.

A detachable adapter transmits torque through a forcing screw to enhance leverage, enabling removal of stuck vehicle components without grime interference.

Arc-ring pins engage inner rod holes via push buttons, preventing jamming from torsional forces.

Spring-loaded handles grip flexible tubing and press barbed fittings into place, reducing manual strength requirements.

A threaded socket adapter uses a concentric pusher shaft to extract jammed fasteners, preventing damage to the socket or fastener during removal.

Linear drive projection confines hook motion to prevent radial sweeping, eliminating misalignment and uneven wear during insertion.
