Contact Driving Mechanisms TRIZ Cases
- DC Isolating Switch Cam Structure for Fast Arc Extinction
An arc-groove cam shares counter-impact force with the rotating shaft, enabling fast arc extinction while reducing cam shaft fracture risk.
- Machine Tool Switchgear With Adjustable Travel Translation
A mechanical translation unit shortens switching travel versus actuation travel, improving compact fit and compatibility across electric machine tools.
- Geneva Ring Tap Changer Switching for Compact Odd-Even Control
A single Geneva-driven ring stack rotates both current carrier rings together, simplifying odd-even tap switching without interrupting power supply.
- Geneva Tap Changer Switching for Lower Flywheel Energy
A Geneva switching mechanism cuts moving mass in on-load tap changers, improving switching reliability while lowering flywheel energy.
