Contact Driving Mechanisms TRIZ Cases

Monitor switching wear and anomalies by analyzing actuator voltage and current, avoiding dedicated sensors and heavy computation.

Monitors medium-voltage switch wear during manoeuvres by extracting diagnostic waveforms from actuator supply signals without extra sensors.

A barrier-wall lock catch stabilizes the energy storage arm under vibration, preventing accidental circuit opening and enabling controlled release.

A perpendicular transmission layout links modular switch layers to reduce stacking error, shorten switch length, and keep opening and closing synchronized.

Spring-driven contact separation extinguishes arcs in air-insulated power line switches, avoiding SF6 and vacuum bulb cost.

A movable insulating barrier redirects DC arcs into an extinguishing chamber, improving high-voltage interruption while reducing switch size and arc damage.

A selectively opened slide groove and through hole let the slider install without press-fit, reducing wear, deformation, and assembly force.

A movable insulating barrier elongates and redirects DC arcs into an extinguishing chamber, improving interruption rating in compact switch poles.

A mechanically coupled dielectric shield moves with the knife switch lever to protect open contacts without obstructing closure or triggering arcs.

A motor, brake, and slotted disc simplify switchgear actuation while enabling precise position control with compact manual override.

An electroactive polymer film drives a relay rod with magnetic holding, cutting actuator weight and installation space while keeping motion stable.

Aligned magnetic limbs create flux loops that hold switch positions without detents, reducing friction, wear, and operating difficulty.

A translating motion member resets the release before rotation, preventing incomplete reset and switch-on or switch-off failures.

Magnetic limb alignment holds a switch actuator in multiple positions without contact, cutting wear, noise, and haptic friction.

A segmented groove and protrusion mechanism enables bidirectional switching while preserving free tripping when the handle is blocked.

Meshed rotary parts synchronize dual movable contacts to save installation space and keep contact separation timing precise.

A plunger-actuated contact mechanism enables single-step high-power connection and disconnection while reducing arcing during plug insertion and removal.

A holding stop and elastic ratchet shift absorb spring force in a switching mechanism, reducing shock, wear, and contact-closing stress.

A rotary knob drives a slider across PCB contacts to simplify dimming control, improve sealing against moisture, and cut switch cost.

A hinged dial member drives a sliding contact across PCB contacts, simplifying dimming adjustment while saving lamp space and easing assembly.

A movable input member with elastic positioning and signal detection enables multi-function switching in less space with simpler, more reliable operation.

A dead-center cam and energy-storage spring boost switch contact opening and closing speed while lowering operating force and fusion risk.

A cam, control lever, and locking member mechanically limit moving contact rebound during opening to prevent secondary electric breakdowns.

A ratcheted disk and coordinated securing assembly keep multi-pole switch sequencing aligned under heavy vibration for rotor-blade de-icing.
