Spanners TRIZ Cases

A nested cam ring and angled grooves increase hammer rotation within limited axial movement, supporting higher torque and stiffer springs.

See how a digital torque wrench converts rotation into linear movement for faster, easier torque adjustment and accurate display.

Retractable pins retain the splined drive member during torque transfer, enabling tool changes without a separate retainer.

An ejector-powered suction path removes torque-broken nut pieces during fastening, avoiding manual cleanup and assembly delays.

Traditional pins and staples can be removed from erosion-control mats; a hex-head shaft with a multi-turn coil provides tool-driven anchoring.

An elongated tool uses a nozzle recess, through-aperture, and storage receptacle to simplify nozzle removal and installation in powered sprayers.

Load cells and strain gauges give a microprocessor real-time torque data to verify tightening, detect over-rotation, and flag erroneous tool adjustments.

Variable handle force can distort torque readings; dual strain gauges on the deflection member maintain accurate fastener tightening.

Integrated splines bite into damaged fastener heads to transfer torque, prevent slippage, and support clean extraction without residue.

Manual trial-and-error calibration is replaced by a motorized adjuster that sets spring preload until the target torque is reached.

An integrated chain tool, bit holder, wrench set, and storage compartments simplify bicycle repair in a compact format.
