Electric Switches TRIZ Cases

An electromagnetic relay diagnostic device calculates contact-on and contact-off times using optical signals to detect aging degradation defects.

A power controller uses a parallel switching path to dynamically adjust pre-charging duration based on load state-of-charge.

Rotary adjustment eliminates complex Belleville springs to synchronize switch actuation within 0.00005 inches tolerance.

Positioning detection elements under key tops enables early water immersion identification before damage occurs.

A circuit breaker incorporates a detachable data processing module to output real-time state parameters, reducing installation complexity and maintenance costs.

A glucose test device automates lancet and strip replacement using a motorized push rod and locking component.

An elongated trip member connects end-to-end circuit breakers for simultaneous tripping, reducing the number of unique parts required.

Segmented housing and bridge design simplify assembly while dielectric seals inhibit arc transfer between chambers.

Lateral ribs on the plunger engage housing cup recesses to prevent jamming in low-profile modules while a labyrinth seal blocks water ingress.

Vertical hollow body reduces horizontal footprint for narrow pump chambers while maintaining float reliability.

A thermally conductive plastic arc quenching device extinguishes electrical arcs using a single integrated component.

Segmented lug-receptacle connections automate flap assembly, reducing production complexity while maintaining stability under high air pressure.

Two antennas detect the actual switching state via radio transmission, preventing undetected contact welding in safety relays.

A power node switching center detects faults within 50 microseconds and interrupts current via parallel electronic paths.

A vent hole positioned at the casing-base junction extinguishes passing flames through optimized dimensions.
