Corona Discharge TRIZ Cases

Multiple needle electrodes and perimeter ground cells generate uniform high-density plasma over larger areas while limiting ozone buildup.

Sensed electrical characteristics let a static eliminator identify air, nitrogen, or argon and switch voltage modes to avoid arcing.

Ion sources raise air charge density so a grounded collector can draw more current from a static electric field and increase usable wattage.

Dual current detection at earth and front mesh improves short- and long-term ion balance, stabilizing static elimination.

A plastic-ceramic hybrid carrier enables high-temperature resistor pastes, cutting scrap and supporting stable ionization in ATEX settings.

Dual current feedback from ground and front mesh electrodes stabilizes both long-term and short-term ion balance in static elimination.

Asymmetrical half-wave control adapts ion balance to surface charge polarity, enabling residual charges below +/-10V without extra hardware.

A coaxial tube with a high-voltage outer conductor draws electrons from cloud bottoms, lowering cloud voltage while storing usable energy.

Controlled surface resistivity in an ionizer cover or housing cuts induced voltage on nearby parts while preserving neutralization and ESD suppression.

Segmented thread flanks lock an ionizer emitter nozzle against pressure-driven ejection while reducing installation turns and operator fatigue.

Varying thread flank angles and shelf locking make ion emitter nozzles easier to install while resisting pressurized ejection and gas leakage.

Balance-voltage feedback adjusts positive and negative ion pulse timing to improve charge neutralization and reduce swing voltage.

Ionized gas routed through electrode channels and nozzle outlets improves spatial ion uniformity, reducing residual electrostatic charge.

Integrated holder grooves align high-voltage and ground electrodes to sustain a uniform field, extending life and suppressing discharge noise.

Standardized ion generator modules join into custom-length HVAC bars, cutting lead time while preserving flexible air-treatment installation.

A gas discharge tube clamps excess high voltage in an anti-static emitter circuit, enabling stable charge neutralization on moving webs while reducing shock and fire risk.

A line-contact hold-down keeps the corona electrode core aligned while allowing thermal expansion that prevents brittle ceramic casing rupture.

Alternating pulsed DC and relaxation modes cut specimen static quickly while restoring ion balance in an electronic balance windshield.

A carbon fiber brush emitter boosts ionic wind cooling in compact electronics while improving electrode durability and reducing ozone generation.

A movable platen shifts piezoelectric samples between corona exposure and voltmeter measurement for faster, more uniform poling.

Built-in measurement, timestamping, and nonvolatile history storage enable strict static control on production lines without added management burden.

Balance-voltage feedback adjusts positive and negative ion duty cycles to keep charge neutralization within +/-5V and reduce swing voltage.

Multiple carbon fibers replace fragile wire or needle emitters to raise ionic wind cooling, cut ozone, and extend electrode life.

Gold-coated copper electrodes on a plastic substrate prevent oxidation, extending lifespan and lowering costs compared to ceramic designs.
