Metal-Working Hand Tools TRIZ Cases

Pivotable press rings connected by an articulated element apply axial compression via a lever effect, reducing stress on brittle workpieces.

A combined tool device integrates pipe expansion and sleeve pressing functions within a common housing.

A tool bar backstop mechanism secures threaded connections to prevent loosening and slippage during operation.

A plastic oil filter removal tool uses a flexible cover portion to create a tight seal against the vehicle surface.

Motorized lever assemblies on a shared cross-member rotate both suspension arms at once, eliminating manual repositioning and reducing operator effort.

Segmented collet segments flex inward to center a cup plug, preventing deformation during retraction.

A spring compressor integrates anti-rotation projections into a spherical contact surface to transmit axial force while allowing angular compensation.

A dent removal tool handle features a curved body and flared collar to enable precise one-handed operation.

Button protrusions engage side openings on accessories, resolving slow attachment speeds while maintaining secure connection reliability.

Electric motor drives a dual-part gear system to rotate a spindle wheel and nut, creating axial feed for the press piston.

A hinged pipe alignment clamp uses adjustable screws to secure segments without requiring full pipe length.

A dent repair system uses a gear and retention ring to enable one-handed tool rotation and secure articulation.
