Spark Gaps TRIZ Cases
- Electric Pulse Fragmentation Circuit for Reliable Quartz Breakage
IGBT-switched pulse generation replaces failure-prone Marx generators to fracture quartz along impurity boundaries with lower energy use.
- Acoustic Fire Detection in Utility Tunnels Under High Noise
Real-time acoustic sensing filters tunnel noise to detect electric sparks early and infer fire risk where CCTV and optical sensors fail.
- Corona Igniter Assembly With Deformed Shell for Joint Durability
A plastically deformed shell conforms to a monolithic insulator, removing failure-prone joints and improving igniter durability.
- Iridium Spark Plug Electrode Laser Welding
Laser welding a punched iridium cup onto the center electrode replaces complex powder metallurgy, reducing production costs while maintaining wear resistance.
- Spark Plug Insulator Retention via Segmented Shell Design
Solid lower seat and ring distribute assembly loads to protect the insulator, resolving strength versus size trade-offs.
- Spark Plug Ground Electrode Convex Fusion Joint
Fusing precious metals into the ground electrode convex portion improves joint reliability and reduces demand voltage by enhancing thermal conductivity.
- Electro-discharge Coating for High-Temperature Sliding Surfaces
Electro-discharge surface treatment deposits hard and lubricating materials onto sliding surfaces, resolving high-temperature wear and oxidation issues.
- Green Compact Electrode for Electric Discharge Surface Treatment
A green compact electrode uses controlled powder particle diameters to form coatings via electric discharge energy.
