Circuit-Breaking Switches For Excess Currents TRIZ Cases
- Protective Switch Status Detection Using Optical Feedback
Optical indicators on a protective switch assembly display blade positions, preventing unintentional device disabling during maintenance.
- Direct-acting electromagnetic trip device with simplified regulation
A direct-acting electromagnetic trip device uses a rotary knob and regulation rod to adjust tripping current via an integrated elastic element.
- DDR Memory Power Management via Hybrid Cycling Controller
A power management system switches DDR memory between parallel and serial transmission modes using a hybrid cycling controller.
- Self-supplied Electronic Protection Device for Circuit-breakers
Microcontroller-based protection device segments instantaneous short-circuit functions to reduce start-up time below 2 ms.
- Thermostat Metal Compensator Dimple Design for Circuit Breakers
Stamping dimples in thermostat metal adjusts effective length to compensate for ambient temperature changes without increasing shock sensitivity.
- Contactor Crossbar Segmentation for Synchronized Contact Timing
Segmented crossbar mechanism aligns contact timing to reduce arc duration and wear during overcurrent events.
- Electromagnetic Contactor Buffer Spring Core Collision
Buffer springs between the fixed core and coil bobbin reduce collision velocity, mitigating mechanical abrasion in electromagnetic contactors.
- Circuit Breaker Trip Unit Strain Relief Mechanism
Strain relief mechanism with tether and thumb screw resists flexing to prevent accidental disconnection of wiring in circuit breakers.
