Portable Power-Driven Tools TRIZ Cases

Rigid ring member clamped between casing and cylinder unit maintains constant distance around the valve knob.

An intermediate flange with a longitudinal slot allows axial insertion of drive components, eliminating complex lateral wobble finger assembly.

A rotary tool adjusts its excessive rotation threshold based on monitored use state information.

A tool base module integrates a drive unit with a coupling device featuring mechanical and electrical interfaces for attachment connections.

A segmented anvil fitting portion with convex curved surfaces accommodates axis misalignment, reducing radial vibrations during screw fastening.

A forearm brace transfers motor vibration from a wrist connector to the operator's arm using linkages and dampers.

Segmenting the control device from the radio module enables wireless data exchange without permanently increasing apparatus complexity.

A power tool gear shift mechanism converts turning motion into linear thrust to engage transmission gears.

A tool support apparatus uses a pivotable ring member to secure equipment from external structures.

An impact wrench uses a longitudinal damper to absorb striker kinetic energy and reduce harmful vibrations transmitted to the user.

Rotating urging element drives axial shifting element to change gears, reducing volume and structure complexity in handheld power tools.

Removable arm assembly connects accessory housing to power tool handle clamp, resolving rigid coupling complexity during rotation.

A translucent ring-shaped lighting module integrates light sources into a handheld power tool base plate to illuminate the workspace.

A power head housing features a barrier member with heat dissipating properties to create a localized cooling zone.
