Thermally Actuated Switches TRIZ Cases
- Alloy Thermal Fuse Composition for Fast, Low-Loss Temperature Protection
A Sn-Pb-Bi-Sb-Ni fuse alloy enables direct PCB soldering, cuts casing-related heat loss, and melts quickly for reliable temperature protection.
- Porous Metal Surface Mount Fuse for Reflow-Stable Current Interruption
Capillary-fed flux in a porous metal layer keeps a lead-free surface mount fuse stable in reflow and enables timely current interruption.
- Flat Surge Protector Layout for Ultra-Thin Tripping Assembly
A flat surge protection component and side-mounted fuse shrink tripping width to 9-12 mm while preserving surge protection and trip reliability.
- Layered Meltable Conductor Fuse for Wider Over-Voltage Protection
A layered low-melting conductor and heating element speed fuse blowing and widen operating current protection in compact electronics.
- Bimetal Contact Protection Structure to Prevent Welding
Thermal inversion in a bimetal member separates a movable arm from a fixed terminal to interrupt abnormal current and prevent contact welding.
- Monolithic SMA Actuator With Integrated Strain Sensing for Position Control
Resistance from SME and PE sections enables sensorless SMA position estimation and current control under dynamic stress.
- Contact Energization Circuit for Pulse Cleaning Without Signal Distortion
Cyclic current pulses clean monitor contacts in the signal circuit itself, limiting power use while avoiding distortion during target value queries.
- Pellet Thermal Fuse Insulation Structure for High-Temperature Cutoff
An insulating tube with multi-layer sealing resin improves high-temperature insulation and reliable circuit disconnection in a pellet thermal fuse.
- Inductive Bimetal Switch Testing for Fast Localized Heating
An induction coil heats the bimetal directly for faster, precise switch testing without warming nearby heating-device components.
- Self-Powered Fixed-Temperature Fire Detection Without Wiring
Using a shape memory alloy spring, this fire detector removes wiring and batteries while enabling real-time wireless alerts.
- Overcurrent Protection Device Using Magnetic Shape-Memory Alloy Trigger
A magnetic shape-memory alloy trigger element deforms under thermal or magnetic stimuli to interrupt circuits.
- Composite Fusible Element for Lead-Free Circuit Protection
A layered fusible element uses a low-melting second metal layer to erode a high-melting first layer during over-voltage events.
