Spark Gaps TRIZ Cases

Resistance and laser weld pools attach a noble metal firing tip to a spark plug center electrode, reducing erosion and breakdown voltage.

A spark plug ground electrode design uses a 2 to 18 micrometer plated layer on pre-formed protrusions.

A radiation heat dissipation layer converts thermal energy to electromagnetic waves within confined mobile device spaces.

A spark plug stream shaper orients air-fuel vortexes toward the combustion chamber center.

Talc powder cushions the insulator against crimp forces, reducing breakage risk while maintaining gastightness under combustion pressure.

Chromium and aluminum additions in the nickel alloy base create oxidation-resistant layers that prevent joint cracking under thermal cycles.

Regulation member constrains ground electrode front end surface during spark gap formation to ensure precise center electrode alignment.

Segmented electrodes in a pre-chamber igniter reduce ignition delay and heat loss during high EGR operation.

A press pin positions a spiral feature to form a removable green body section during spark plug insulator manufacturing.

Controlled pulse discharge with specific grain diameter electrodes prevents porous coatings and weld cracks in thin materials.

Embedding conducting elements in a ceramic matrix shapes the electric field to suppress arc discharge and maintain multiple ion streams.

A spark plug precious metal region uses a ductile base material coated with a brittle metal layer to enhance burn-off resistance.
