Solution Overview
Problem
Existing aerosol generating systems struggle to provide the best smoking experience by efficiently heating aerosol generating articles without burning them, and they often fail to maintain uniform atomization during puff actions.
Innovation Solution
An aerosol generating system that includes an aerosol generating article with distinct medium portions and a heating element that surrounds the article, with varying heating element areas to optimize heating and adjust inhalation resistance, ensuring uniform atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating element surrounds the aerosol generating article to heat it, then aerosol generation is achieved, but the article may be burned instead of efficiently heated
Solution Approach 1:
The heating element is designed with different heating areas corresponding to different medium portions (first and second medium portions with different aerosol generating materials). This local differentiation allows each portion to be heated to its optimal temperature without burning, achieving efficient aerosol generation while preventing harmful burning effects.
2Productivity
If various components are arranged in the aerosol generating article, then aerosol generation capability is improved, but inhalation resistance becomes uneven
Solution Approach 1:
Different medium portions with different aerosol generating materials are assigned different heating areas. The first medium portion receives a first heating area and the second medium portion receives a second heating area, creating localized quality differences that balance aerosol generation efficiency with inhalation resistance across different components.
3Device complexity
If uniform heating is applied to all portions, then simple control is maintained, but atomization becomes non-uniform during puff action
Solution Approach 1:
The heating element is configured with different heating areas for different medium portions, creating localized heating zones. This local quality differentiation ensures that each portion is heated according to its specific requirements, maintaining atomization uniformity during puff action while keeping the control structure relatively simple.
