Electric Heating TRIZ Cases
- Multi-State Heater Control for Faster Heating With Lower Energy Use
Temperature-threshold state control switches a heater between high, low, and stand-by power to cut energy waste while maintaining room temperature.
- Substrate Cooling Shield Layout for Low-Contamination Vacuum Transfer
A cooled surrounding shield traps gas released from the substrate holder, cutting vacuum-transfer contamination and stabilizing substrate cooling.
- Distributed Heatsink Switching for Compact Line Voltage Thermostats
Parallel semiconductor switches on multiple heatsinks spread heat inside a line voltage thermostat, enabling smaller layouts and flexible screen placement.
- Dual Heating Rod Hot Water Tank Using Direct PV Preheating
Direct PV heating preheats tank water through a second rod, cutting inverter losses and reducing grid electricity use.
- Conveyor Toaster Speed Control for Consistent Cooking
Sensor-based control adjusts conveyor speed and cook time from estimated temperature and product load to keep toaster output consistent.
- Wireless Heated Drinkware for Dishwasher-Safe Temperature Control
Wireless heating, sensors, and control circuitry keep drinks at a selected temperature in dishwasher-safe mugs and bottles.
- Continuous-Flow Heater Dry-Fire Detection via Timed Re-Energizing
Brief heater energizing plus a wait-and-recheck sequence detects dry fire and low flow before the fusible link melts.
- Electric Heater Fault Indication Circuit for Power Interruption Detection
A parallel resistance branch activates a visual indicator when a temperature cutoff interrupts heater power, enabling fast fault diagnosis.
- Electric Water Heater Dry-Fire Protection by Pulsed Element Heating
Intermittent element actuation and local temperature sensing prevent dry firing while still confirming heat transfer when water is present.
- Dual-Element Water Heater Control for Peak Grid Load Management
A dual low- and high-power heating element lets water heaters cut peak grid demand while maintaining hot water and enabling utility load control.
- Relay-Triac Heater Control for Pilot Wire and Conventional Loads
A parallel relay-triac control unit detects heater type, unifies pilot wire and conventional heater control, and avoids relay sparking.
- Multi-Heater Fluid Heating Control for Uniform Process Liquid Temperature
Alternating multiple heaters keeps process liquid heating uniform while limiting simultaneous heater load and extending heater life.
- Electric Kettle Cut-Off Temperature Control to Prevent Overshoot
A control unit calculates cut-off temperature from heating power, base mass, surface area, and sensor delay to avoid water overshoot.
- Insulated Food Container Thermal Inertia for Stable Hot Holding
A modular insulated container and detachable heating body use thermal inertia to hold food at stable serving temperature with lower energy loss.
- Coffee Machine Shutoff Circuit With Separated Signal Switch
A controller-driven signal switch separates manual shutoff from the power switch, saving space and improving coffee machine installation flexibility.
