Battery Cutoff Switches TRIZ Cases

Flame-retardant plastic chamber walls improve arc insulation, cut leakage current, and support fast opening in automotive pyrotechnic breakers.

Sequentially cutting parallel conductor portions with a gas-driven pin shortens arc duration and improves circuit interrupting capability.

Deformable spacers delay piston motion until pressure builds, improving conductor severing and arc extinction across temperature changes.

A squib-driven piston fractures the busbar in milliseconds while arc suppressant filler extinguishes arcs for safer high-voltage fault isolation.

Conductive cooling features create a secondary arc path that dissipates energy and limits heat and pressure during high-current circuit breaking.

An outer piston groove with adjacent seals directs a small quenching agent charge into the arc zone, cutting housing pressure and stress.

A resin-embedded conductor and internal gas space contain arc-generated conductive gas, reducing leakage and insulation deterioration.

A pyrotechnic plunger forces the contact bridge open in under 2 ms, stopping extreme overcurrent and preventing contact re-closure.

Dual coolant placement cools the cutoff point and arc-extinguishing region to speed circuit interruption and reduce arc damage.

A projectile-cut circuit breaker uses heat-modified resin and coolant material to quench arcs fast and preserve insulation resistance.

A thermoelectric temperature sensor powers the pyrotechnic fuse control circuit, removing battery maintenance while preserving trigger reliability.

A single bridging element shorts three phase lines into a common neutral point, simplifying electric machine discharge and stabilizing contact.
