Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices fail to provide an appropriate balance between aerosol transfer amount and suction resistance, which affects the smoking experience.
Innovation Solution
The device incorporates a heating element that passes through a hole in the accommodation part, with a specific ratio of cross-sectional areas to optimize airflow and aerosol transfer, ensuring an enhanced smoking sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the hole size in the accommodation part is increased to improve aerosol transfer amount, then aerosol transfer amount is improved, but suction resistance decreases (affects smoking experience)
Solution Approach 1:
The patent applies parameter changes by optimizing the cross-sectional area ratio of the hole to the heating element within a specific range (1.8-3.6). This quantitative parameter adjustment resolves the contradiction by finding the optimal balance point where aerosol transfer amount is maximized while suction resistance remains within acceptable limits for smoking experience.
2Power
If the heating element dimensions are changed to improve heating efficiency, then aerosol generation is improved, but the fit with the hole and aerosol transfer are affected
Solution Approach 1:
The patent resolves this contradiction by establishing a specific parameter relationship: the cross-sectional area ratio between hole and heating element should be 1.8-3.6. This parameter constraint ensures that heating efficiency is maintained while optimizing aerosol transfer, preventing either parameter from compromising the other.
3Quantity of substance
If the accommodation part design is optimized for aerosol transfer, then aerosol delivery is improved, but manufacturing complexity increases
Solution Approach 1:
The patent simplifies manufacturing by defining a specific parameter range (1.8-3.6 for the area ratio) rather than requiring complex geometric optimizations. This parameter-based approach allows standard manufacturing processes to produce the optimal design, avoiding excessive manufacturing complexity while achieving improved aerosol transfer.
