Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If circumferential heating or central heating modes are used, then the heating process is simple, but the temperature distribution becomes uneven
Solution Approach 1:
The heating function is segmented into multiple independent heating units arranged around the aerosol-forming matrix. Each heating unit independently heats its adjacent region, and the combined effect achieves uniform temperature distribution throughout the matrix, resolving the contradiction between simple heating structure and uniform temperature distribution.
Solution Approach 2:
Different regions of the aerosol-forming matrix are heated by locally positioned heating units. Each heating unit provides localized heating to its adjacent region, ensuring that temperature is uniformly distributed across the entire matrix. This local quality approach allows simple heating elements to achieve uniform overall heating.
2Device complexity
If conventional heating methods are used, then the device structure is simple, but aerosol delivery becomes inconsistent
Solution Approach 1:
The heating device is segmented into multiple heating units that independently and uniformly heat different regions of the aerosol-forming matrix. This segmentation ensures consistent temperature distribution throughout the matrix, which directly improves aerosol delivery consistency and reliability.
Solution Approach 2:
The multiple heating units are designed to provide equipotential heating across the aerosol-forming matrix, meaning all regions receive approximately equal heating intensity. This equipotential approach ensures uniform temperature distribution, which is essential for consistent and reliable aerosol delivery.

AI summary
A smoking article comprises a smoke generating section, having a tube wall and a tube cavity; the tube cavity being configured to contain the aerosol-forming matrix; an infrared radiation layer, being formed on at least part of the inner surface of the tube wall; the infrared radiation layer being configured to be heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared radiation layer is arranged on the inner surface of the tube wall, so that the infrared radiation layer is heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared rays have relatively long wavelength, and they can penetrate substance and “resonate” with molecules and atoms inside the substance and produce strong vibration and rotation, so that the temperature of the substance rises to achieve the purpose of heating.
