Force Measurement Using Counterbalancing Forces TRIZ Cases

Uniform node-by-node loading and interpolation calibration turn pressure pad sensor outputs into reliable swelling pressure maps for pouch cells.

Known weights calibrate each sensing node to correct output variation and map pouch cell surface pressure more accurately.

A fluid-filled textile sensor routes hand forces to a remote pressure element, improving whole-hand force measurement without bulky glove hardware.

Bidirectional switching in an electromagnetic force-compensation coil keeps current magnitude constant to reduce heating drift and improve weighing accuracy.

A fully-passive sensor system uses RF backscattering to transmit pressure data without batteries.

A measuring device uses water flow and spring dynamometers to suspend a circular valve core for precise torque analysis.

A sensor system calculates secondary battery deformation stiffness by differentiating force with respect to thickness during volume changes.

A spring cable mechanism produces non-linear counter torque that matches varying display load moments, maintaining zero net torque throughout the rotation.

Electromagnetic mechanisms hold the weighing pan in a constant position without mechanical linkages, eliminating bearing forces and corner load errors.

A hyperelastic microfluidic film measures bending curvature directly using embedded eutectic gallium indium channels.
