Contact Mechanisms TRIZ Cases
- Interlink Arrangement for Independent Grounding Switch Stroke
An adjustable interlink lets a grounding switch stroke be set independently from the circuit breaker, helping prevent voltage surges and cut wind turbine costs.
- Reclosing Switch Actuation With Permanent Magnet Core and Rapid Reset
A permanent magnet core and rapid reset mechanism simplify reclosing switch actuation for stable contact opening and closing with fewer faults.
- Reinforced Keycap Support Structure for Steady Low-Profile Key Travel
An embedded high-modulus reinforcement stiffens the keycap support to keep low-profile keys moving levelly without extra balance bars.
- Slim Wireless Sensor Assembly for Concealed Door-Window Retrofitting
A sub-5 mm wireless sensor assembly fits door and window cavities for hidden retrofit installation without drilling, insulation loss, or visible hardware.
- Rotary Audio Control With Non-Contact Touch Detection
Electromagnetic induction powers a rotary audio control without contact, enabling precise touch detection while avoiding mechanical noise and drag.
- DC Relay Mover Assembly With Supporting Pin for Contact Stability
A C-shaped supporting pin secures the movable contact in a DC relay, preventing escape under weak spring support or external force.
- Long Key Scissor Mechanism Without Balance Rod Noise
An integrated dual-scissor linkage keeps a long keycap level while removing balance rods that add assembly damage risk and collision noise.
- Light Adjusting Structure With Mesh Pattern for Keyboard Light Leakage
A checkerboard or mesh light-absorbing pattern narrows keyboard backlight exit angles to cut light leakage and user glare.
- Tubular Breaking Member Structure for Arc Erosion Reduction
A nested inner and outer tubular breaking member extends and traps the arc to cut material loss and improve interruption reliability.
- Relay Contact Spring Assembly for Multi-Variant Switching Force
A latch-biased contact spring balances contact force for multiple relay variants, cutting part variety, power use, and contact bounce.
- Dual-Movable Vacuum Interrupter for Fast HVDC Short-Circuit Switching
Two independently driven movable electrodes speed short-circuit making and breaking while reducing impact, misalignment, and wear in HVDC interrupters.
- Multi-Pivot Key Structure for Stable Low-Noise Keystrokes
Multiple pivoting portions and linked brackets replace the balance bar to steady keycap travel and reduce bottom-plate collision noise.
- Illuminated Keyswitch Spacer Layout to Prevent LED Interference
A flat spacer recesses the light source below the base plate to avoid keycap interference, protect the LED, and keep the keyswitch profile even.
- Dual-Moving Vacuum Interrupter for Ultrafast Contact Separation
Opposed contact motion with a Thomson coil or piezo actuator speeds vacuum interruption while reducing moving mass and actuation energy.
- Adjustable Contact Bridge Spacing for Secure Circuit Isolation
A shaft-end setting device enables stepless post-manufacturing contact spacing adjustment to meet isolation requirements in electrical load switches.
- Relay Spring Self-Locking Structure for Small Relay Assembly
A resilient spring lock on the base prevents spring disengagement in small relays, improving press-fit retention, sealing, and manufacturing cost.
