Emergency Springs TRIZ Cases
- Air Circuit Breaker Contact Spring Layout for Stable High-Current Contact
Varying spring force across outer and center movers counters electric repulsion, keeping breaker contacts stable without reducing durability.
- Dual-Contact Fusible Disconnect Switch for DC Arc Containment
Dual switch contacts and a retractable fuse module contain DC arc energy, limiting contact wear in compact high-energy disconnects.
- Electromagnetic Relay Spring Assembly With Insulating Opening
An insulating opening lets the return spring be inserted and visually checked, simplifying relay assembly while keeping the relay compact.
- Trigger Switch Contact Mechanism to Prevent Chattering
A split movable contact mechanism uses spring-biased and actuated contact pieces to stop chattering, reduce slippage, and stabilize switch timing.
- DC Relay Mover Assembly With Magnetic Circuit for Contact Stability
Upper and lower yokes offset contact repulsion in a DC relay mover assembly, helping maintain stable contact pressure and power transmission.
