Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If far infrared coating is applied to the outer surface of the base, then the aerosol-forming matrix can be heated evenly through penetration, but heat loss occurs when infrared rays penetrate the base
Solution Approach 1:
The patent inverts the conventional design by moving the infrared electrothermal coating from the outer surface to the inner surface of the base. This inversion eliminates the need for infrared rays to penetrate the base, thereby preventing heat loss while still achieving uniform heating of the aerosol-forming matrix through direct radiation contact.
2Power
If far infrared coating is used to heat the aerosol-forming matrix, then heating can be achieved, but heat loss reduces heating efficiency
Solution Approach 1:
The patent extracts the infrared electrothermal coating from the outer surface and relocates it to the inner surface of the base. This extraction eliminates the harmful penetration path through the base, removing the source of heat loss and thereby improving overall heating efficiency.
3Temperature
If infrared rays penetrate the base to heat the matrix, then even heating is achieved, but energy is wasted
Solution Approach 1:
By inverting the coating position from outer to inner surface, the patent achieves energy-efficient heating without compromising heating evenness. The inner surface placement allows infrared rays to directly radiate onto the aerosol-forming matrix, maintaining uniform temperature distribution while eliminating energy waste from base penetration.
