Capacitor With Electrode Area Variation TRIZ Cases
- Capacitive Rocker Potentiometer With Stationary Electrodes
Stationary electrode plates and a moving insulation sheet vary capacitance without friction, cutting power use and vibration-induced sensing errors.
- Dual-Bellows Vacuum Capacitor for High-Speed Capacitance Control
Opposing main and adjustment bellows cancel retraction forces, enabling faster, finer vacuum capacitor capacitance control.
- Vacuum Capacitor Brazing Structure for High-Frequency Heat Reduction
Active metal brazing and field-relaxing rings cut dielectric, hysteresis, and eddy-current heating in vacuum capacitor joints.
- Rotating Capacitor Bearing Layout for Vacuum-Safe Maintenance
Placing the bearing on the atmosphere side lets the rotating capacitor be serviced without breaking vacuum, cutting accelerator downtime.
- Shape-Memory Adjustable Capacitor for Wide-Range Low-Voltage Tuning
Shape memory alloy actuators shift capacitor plate overlap to deliver precise wide-range tuning with lower voltage and less noise.
- Coaxial Variable Capacitor With Liquid Dielectric for RF Impedance Matching
Liquid dielectric and interdigitated coaxial blades raise capacitance, cooling, and voltage handling for RF impedance matching.
- Electret Package Sealing With Hydrogen Getter Charge Protection
A hydrogen getter inside the sealed electret package adsorbs hydrogen without high-temperature activation, reducing charge decay and extending element life.
- Capacitive Trigger Switch Sensing for Magnetic Field Immunity
Capacitance-based trigger sensing replaces magnetic detection to keep power tool switch input accurate and low-friction near strong magnetic fields.
- Capacitor-Based High-Voltage Contactor for Low-Heat Hold-In
Electrostatic capacitor plates hold a high-voltage contactor closed without continuous current, cutting heat versus solenoid designs.
- MEMS Capacitive Sensor Negative Second Derivative Design
Segmented stator and rotor protrusions generate negative second derivatives of capacitance, enabling resonance frequency tuning with lower voltage requirements.
- Multi-Sectional Capacitor for High-Frequency Decoupling
Multi-sectional conductors in embedded capacitors reduce impedance and broaden decoupling bandwidth for high-speed signal integrity.
