Electrothermal Relays TRIZ Cases
- Washing Machine Door Lock Using DC Electromagnet Release
A DC electromagnet and slider replace slow bimetal locking, enabling immediate washer door opening and preserving lock function during power faults.
- Washing Machine Door Lock With Bell Crank Stroke Amplification
A bell crank multiplies actuator motion to give a washing machine door lock longer catch stroke without added bulk or assembly cost.
- Motor Protector Cover Barriers for Arc Containment
Multiple wall barriers and epoxy-sealed openings block arc travel and flammable gas entry in an enclosed motor protector.
- Battery Pack Fuse Structure for Melted Conductor Containment
Deformation-suppressing electrodes and a suction hole stabilize a battery pack fuse, limiting melt scatter and preserving blowout current behavior.
- SMA Trip Actuator for Compact Circuit Breaker Accessory Pockets
A shape memory alloy trip actuator replaces bulky coil and spring assemblies, saving accessory pocket space and reducing mechanical stress.
- SMA Switch Sensing Using Lock-Modified Resistance
A locking mechanism changes SMA wire resistance to indicate switch state while avoiding contact variation and magnetic-field tampering.
- SMA Film Safety Switch for Reversible Li-Ion Thermal Cutoff
A shape memory alloy film switch cuts Li-Ion current during overheating, then reconnects as temperature normalizes.
- Bimetal Heating Assembly for Automatic Overheat Disconnection
A soft solder spot and bimetal strip disconnect the heater during dry operation, preventing overheating and undesired vapor release.
- Bulk Ferroelectric Thermal Switch for Room-Temperature Heat Control
An electric field tunes bulk ferroelectric thermal conductivity, overcoming thin-film limits and enabling room-temperature heat switching.
- Electrostrictive Thermal Switch Stack for Electric Heat Flow Control
An electrostrictive layer stack uses an applied electric field to modulate thermal conductivity and control heat flow over a wider temperature range.
- Hybrid Dimmable Optical Switch for Fast High-Contrast Transitions
Dynamic thermal coupling helps dimmable optical switches achieve faster, more stable high-contrast state changes for displays and shutters.
- Temperature-Controlled Switch Actuator Using Shape Memory Alloy
A shape memory alloy actuator switches electrical contacts by temperature-driven expansion, cutting mechanical complexity, size, and maintenance.
- Shape Memory Alloy Power Switch for Lightweight Contact Isolation
Shape memory alloy actuators replace heavy coil mechanisms to switch contacts with lower weight, better isolation, and efficient thermal cycling.

Electro-thermal base excitation drives micro-cantilevers at resonance to deliver high-frequency, high-amplitude tip vibration with better actuation efficiency.
- Battery Pack Fuse Housing Venting for Blowout Pressure Relief
Housing openings vent blowout pressure while external terminals trap vaporized material, protecting high-current battery pack fuses from damage.
- Shape-Memory Dead-Facing Switches for Resettable Cable Disconnection
A shape-memory actuator opens bridged contacts and inserts a shutter to cut power quickly without pyrotechnic debris, while allowing reset and testing.
- Bistable SMA Inertial Actuator for Temperature-Stable Switching
An inertial element and elastic locking force let SMA wires switch quickly while blocking accidental actuation from ambient heating.
- VO2-CNT Actuator for Fast Thermal Response
Vanadium dioxide phase transition drives fast bending, overcoming slow response limits of composite actuators.
- Switching Actuator Reduces DALI Standby Energy
Switching actuator reduces standby energy consumption by activating only needed components via bidirectional DALI communication.
