Mechanical Vibrations Separation TRIZ Cases
- Magnet-Free Vibration Actuator With Bellows Elastic Support
A coil-core actuator uses bellows-shaped elastic support to deliver strong touch vibration while reducing thickness and magnet cost.
- Direct-Bonded Semiconductor Membranes on Piezoelectric Substrates
Direct bonding removes intermediate layers between semiconductor membranes and piezoelectric substrates to improve strain transfer and biocompatibility.
- Leaf-Spring Oscillatory Actuator for Torsional Resonance Suppression
Elastic members bridging spiral leaf-spring arms suppress torsional resonance while preserving oscillation output and natural resonance stability.
- Active Inductor Driver Circuitry for Tunable Piezoelectric Transducers
Active inductor circuitry replaces bulky transformers in piezoelectric transducer drivers, tuning frequency response to extend range and reduce interference.
- Vibration Actuator Venting Structure for Pressure Damping
Vent holes in the actuator case release compressed air, preserving tactile vibration output while blocking dust in electronic devices.
- Electrodynamic Actuator Support Structure for Low-Crosstalk Excitation
Linear guides and an elastic member isolate high-frequency vibration, suppress non-drive-axis crosstalk, and improve multi-axis excitation accuracy.
- Hydraulic Steering Wheel Vibration for Softer Driver Warnings
Fluid pressure and electrorheological actuation create softer steering wheel warnings with less noise while keeping feedback clear.
- Suspended Vibration Exciter Layout for Balanced Screen Sounding
A suspended mass block and elastic member layout improves vibration balance and stability while combining screen sounding and tactile feedback.
- Piezoelectric Diaphragm Bonding Layout for Conductivity and Strength
A split adhesive layout places conductive adhesive at the center and thermosetting adhesive at the edge to keep piezoelectric diaphragms conductive, strong, and lower cost.
- Coaxial Unbalance Exciter Layout for Compact Soil Compactors
Coaxial rotors and unbalance masses cut exciter space, weight, and cost while preserving phase control for soil compaction and maneuvering.
- Lens Holder Buffer Layer for Vibration Stress Relief
A tapered buffer layer between the piezoelectric body and lens holder reduces bonding stress during vibration while preserving water droplet removal.
- Light Transmissive Body Vibration for Clear Field of View
An asymmetric protruding mass shifts droplet motion to the periphery, clearing the optical center while preserving vibration-based contaminant removal.
- Actuator Coil Straddle Wiring for Higher Force and Lower Heating
Wide, thin straddle wiring cuts coil-path resistance, allowing higher actuator current with less heating and more stable assembly.
- Light Transmissive Body Vibration for Clear Central Field of View
Peripheral-biased vibration removes droplets from a light transmissive body while keeping the central field of view clear.
- Ultrasound Generator Frequency Control for Tool Resonance Tracking
Phase-shift feedback adjusts ultrasonic frequency to keep the machining tool at resonance, cutting energy use while improving brittle-hard machining.
