Contact Mechanisms TRIZ Cases
- GFCI Solenoid Cam Mechanism Compact Design
A solenoid assembly actuates a cam mechanism to separate electrical contacts in a ground fault circuit interrupter.
- Electrical Switch Tubular Part Molding Deformation Control
A pull chain electrical switch casing uses a tubular part with transverse recesses to maintain screw thread integrity during molding.
- Safety Switch Latch Mechanism for Cold Environment Stability
A safety switch uses a latch mechanism to lock the rocker in a deactivated position after thermal activation.
- UPS Electromechanical Switching for Low Loss High Speed
High speed electromechanical actuators drive mechanical switches in uninterruptible power supplies to replace semiconductor components.
- Low Power Wall Switch Circuit Using Leakage Current
Wall switch control module operates using leakage current to eliminate the need for a neutral wire, reducing installation costs while supporting CFL loads.
- Door Handle Coupler for Tool-Less Circuit Breaker Mounting
Nested sleeves and a locking lever enable tool-less alignment of the coupler to the circuit breaker, eliminating hazardous enclosure entry.
- Contactor Lead Angling for Heat Dissipation
Angled electrical leads transfer heat from contactors to housings, reducing bus bar weight and assembly size.
- Circuit Breaker Translating Contact Arc Extinguishment
Linear translation of the moving contact utilizes arcing pressure for rapid separation, reducing arc extinguishment time and contact erosion.
- Cantilevered Push Button With Dual Fulcrums
Dual fulcrums prevent non-actuated ends from rising during operation, maintaining a flat appearance while allowing rigid material construction.
- High Voltage Gas Circuit Breaker Link Mechanism
A gas circuit breaker uses a variable link mechanism to pull the cylinder rod, increasing separation speed between arc contacts.
- Actuator Rotational Locking Mechanism for Emergency Stop
Geometric interlocking prevents accidental return to the inactive position, eliminating complex spring-loading and latch mechanisms.
- Nested Cylinder Mechanical Switch for Tactile Feedback and Low Profile
Nesting rotating and guiding cylinders reduces total height while maintaining reliable tactile feedback.
- Low Voltage Arc Flash Switch With Electromagnetic Trigger
A low voltage arc flash switch uses an electromagnetic trigger to break down gaps within a sealed housing.
- Circuit Breaker Reversing Gear Malfunction Detection
A circuit breaker pairs a drive mechanism indicator with a reversing gear deflection lever to detect coupling malfunctions.
- Electromagnetic Relay Card Support via Segmented Protrusions
Segmented base protrusions engage card holes to prevent play during large movements, ensuring stable contact operation.
- Keyboard Key Structure with Segmented Span for Assembly
A keyboard key structure uses a segmented span to adjust assembly force requirements.
- Illuminated Keyboard Metal Dome Electrical Contact
Metal dome contacts replace thin film circuit board holes, simplifying manufacturing and reducing keyboard thickness.
- Cam Torque Amplification for Air Circuit Breaker Draw-In-Out
A cam mechanism amplifies torque to drive the main body, managing heavy loads during connection.
- Relay Contact Piece Terminal Narrow Portion Design
A relay contact piece terminal incorporates a narrow portion to boost assisting force via electromagnetic repulsion while suppressing terminal temperature rise.
- Switch Mechanism for Portable Device Display Pivoting
A sliding component moves along a track to activate switches as the display module pivots relative to the host module.
