Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inductive heating mechanism with susceptors and conductive separators is used, then heating efficiency and aerosol generation consistency are improved, but device complexity increases
Solution Approach 1:
The substrate material is divided into multiple segments by conductive separators, creating discrete heating zones that improve aerosol generation consistency. Each segment can be heated independently by the resonant transmitter, ensuring uniform vaporization across the entire substrate.
Solution Approach 2:
Susceptors and conductive separators act as intermediaries between the resonant transmitter and the substrate material. These components facilitate efficient energy transfer from the electromagnetic field to the tobacco material, improving heating efficiency while maintaining controlled device architecture.
2Object-affected harmful factors
If electrical heating is used to vaporize tobacco without combustion, then harmful combustion byproducts are reduced, but achieving consistent vaporization temperature and performance is difficult
Solution Approach 1:
The resonant transmitter operates in periodic cycles, alternating between heating phases and cooling phases. This periodic action allows precise control over the temperature profile, ensuring consistent vaporization without exceeding combustion thresholds, thereby maintaining reliable performance while minimizing harmful byproducts.
Solution Approach 2:
The system dynamically adjusts heating parameters including power level, duration, and frequency of the resonant transmitter to maintain optimal vaporization temperature. By changing these parameters in real-time, the device achieves consistent performance characteristics while preventing combustion and harmful byproduct formation.
3Manufacturing precision
If conductive separators are used to segment substrate material, then heating uniformity is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive separators are integrated directly into the substrate material structure, merging the separation function with the tobacco matrix itself. This integration approach improves heating uniformity by creating inherent conductive pathways while avoiding the need for separate assembly steps, thereby maintaining ease of manufacture.
