Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If on-off modulation is used to control the heating panel, then the control system is simple, but the temperature profile becomes uneven and energy consumption increases
Solution Approach 1:
The patent implements dynamic voltage modulation by dividing the control into multiple power levels (P1, P2, P3, P4) based on temperature differences. Instead of simple on-off control, the system dynamically adjusts the voltage applied to the CNT coating according to the measured temperature deviation from setpoint, creating a progressive control strategy that maintains temperature uniformity while keeping the control system relatively simple.
Solution Approach 2:
The system changes the electrical parameter (voltage) applied to the heating element based on temperature conditions. By adjusting the voltage to different levels (full voltage for large temperature differences, reduced voltage for smaller differences), the system achieves smooth temperature control and uniform temperature profiles without requiring complex control architecture.
2Device complexity
If on-off modulation is used to control the heating panel, then the control scheme is simple, but energy consumption becomes high
Solution Approach 1:
The patent applies partial action by using different voltage levels instead of always applying full power. When the temperature is close to the setpoint, the system applies reduced voltage (P2 or P3 levels) rather than full voltage (P1), thereby consuming less energy while still maintaining the desired temperature. This progressive approach avoids the energy waste of continuous full-power operation.
Solution Approach 2:
The system implements periodic temperature measurement and voltage adjustment based on the temperature difference from setpoint. By continuously monitoring temperature and periodically adjusting the voltage level according to the measured deviation, the system optimizes energy consumption while maintaining temperature control, avoiding both continuous full-power operation and complete shutdown cycles.
3Temperature
If high voltage is continuously applied to maintain temperature, then the temperature stability is good, but energy consumption increases
Solution Approach 1:
The system employs feedback control by continuously measuring the temperature and comparing it to the setpoint. Based on the temperature difference (ΔT), the system adjusts the voltage level applied to the heating panel. When temperature is stable and close to setpoint, lower voltage levels (P3 or P4) are applied, reducing energy consumption while maintaining temperature stability. When temperature deviates significantly, higher voltage levels (P1 or P2) are applied to restore stability.

Implementation Method 1
an electrical connection in contact with the CNT coating to apply a voltage over the CNT coating
Implementation Method 2
Infrared heating is an addition to the domestic and commercial heating scene. It is emitted from the heater, which then travels unimpeded through the air until it hits an object. The object absorbs the radiation, causing molecules within it to vibrate, producing heat.
