Vibration Measurement In Solids TRIZ Cases

Vessel vibration at harmonic heating frequencies reveals boiling state early, helping induction cookers prevent overflow and suppress resonant sound.

A diaphragm, coil, and collision member combine water level and vibration sensing in one washer sensor, cutting complexity while preserving accuracy.

Automatic timer control in a connected vacuum cleaner tracks hand tool vibration exposure without separate sensors or added tool weight.

Reactive torque sweeps identify motor resonance, gain, and phase for adaptive vibration suppression without mechanical redesign or PLL delay.

Reactive torque sweeping identifies motor natural frequency, gain, and phase to suppress vibration without mechanical redesign.

Combining microphone audio with piezoelectric MEMS motion signals improves surface contact classification and reduces noise-driven errors.

By sensing structure-borne vibrations through vehicle panels, this enclosed transducer avoids visible microphones and resists harsh exterior conditions.

Reference and real-time ultrasonic signals are differenced to cancel structure-borne noise and detect contact or damage through concealed vehicle panels.

Ultrasonic transmit-receive mapping classifies battery states into normal, at-risk, and dangerous zones for earlier anomaly detection.
