Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the entire substrate segment of the aerosol-forming article is heated, then the heating efficiency is improved, but the taste consistency deteriorates over time
Solution Approach 1:
The heating process is segmented into multiple local heating zones around the aerosol-forming article. The microwave heating assembly includes multiple heating regions arranged circumferentially, so that different segments of the article are heated sequentially during rotation rather than all at once. This segmentation allows the heating efficiency to be maintained while preventing rapid depletion of any single region, thus preserving taste consistency throughout the heating cycle.
Solution Approach 2:
The system introduces dynamic rotation of the aerosol-forming article around the central axis during microwave heating. This dynamic movement allows different portions of the article to pass through the microwave heating field sequentially, distributing the thermal energy input over time and space. The rotation speed and heating power are coordinated to ensure consistent aerosol generation, resolving the contradiction between efficient energy use and taste stability.
2Stability of the object's composition
If the aerosol-forming article is rotated during heating, then the taste consistency is improved, but the device complexity increases
Solution Approach 1:
The rotation function and heating function are merged into a single integrated system. The drive assembly is positioned within the microwave heating assembly, and both functions operate simultaneously in the same spatial envelope. The rotating article passes through the microwave field while being driven by the integrated drive mechanism, eliminating the need for separate rotation and heating systems. This merging reduces overall device complexity while achieving consistent taste through continuous rotation and heating.
Solution Approach 2:
The central cavity serves multiple functions: it accommodates the aerosol-forming article, contains the microwave heating field, and provides the rotational path for the article. The drive assembly also serves dual purposes by both rotating the article and positioning it within the heating zone. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining taste consistency through rotation.
3Stability of the object's composition
If local segmented heating is implemented through rotation, then the taste consistency is improved, but the heating time increases
Solution Approach 1:
The rotation and heating processes continue simultaneously without interruption. As the aerosol-forming article rotates through the microwave heating field, heating is applied continuously to different segments in sequence rather than in discrete steps. This continuous action ensures that the entire article is uniformly heated over time, maintaining taste consistency while minimizing the total heating duration by keeping the system in constant operation throughout the heating cycle.
