Protective Switch Details TRIZ Cases

A modular electrical apparatus uses elastic conductive contacts and local selection devices to assign addresses on a shared interconnection bus.

A rotary dual breakpoint moving contact module uses a centrally symmetric bridge and rod-shaped block rotor to balance pressure.

Nested voltage sensor contacts integrate sensing capabilities into the relay housing, reducing catalog numbers without increasing device width.

Segmented intercalary shims adjust the magnetic flux transfer surface, resolving manufacturing tolerance issues while maintaining reliable tripping thresholds.

A molded polymer arc shield apparatus abuts against a contact arm edge and secures via a spring hook aperture to provide structural retention.

Bidirectional deformation reverses over-deformation errors, reducing circuit breaker waste and improving calibration precision.

Segmented switching points prevent contact welding during short circuits, maintaining protective function without oversized components.

Extension portions on toggle links interpose the first link between plate members, eliminating collision and deformation during air circuit breaker operations.

Compares actual electrical signals against target values to identify faulty status changes, enabling permanent central monitoring without manual checks.

A bidirectional DC circuit breaker uses a bridge branch with four commutation arms to interrupt current flow in both directions.

A movable charging apparatus with a power converting module transforms AC grid current into DC battery charge, resolving stationary infrastructure limitations.

Normally closed relay intermediary trips electronic circuit breaker contacts upon monitoring failure, resolving solid-state reliability risks.

A push link featuring a varying cam profile reduces operating force while ensuring reliable circuit breaking during abnormal currents.

A mechanical coupling assembly decouples the drive shaft from the motor and gear train during manual operation.
