An aerosol provision device with a dual air path system, comprising an inner and outer air path defined on the inner and outer sides of the receptacle, which directs airflow through the aerosol generating article to provide cooling and ventilation, enhancing airflow efficiency and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single air path is used to deliver air to the article, then the device structure is simple, but the airflow efficiency and cooling effectiveness are insufficient
Solution Approach 1:
The air path is segmented into two distinct pathways: an inner air path that delivers air directly through the article, and an outer air path that provides cooling air around the heating element. This segmentation allows each path to be optimized for its specific function, improving overall airflow efficiency while maintaining manageable structural complexity through modular design
2Loss of energy
If cooling air is provided around the heating element, then energy efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The air path is segmented into two distinct pathways: an inner air path that delivers air directly through the article, and an outer air path that provides cooling air around the heating element. This segmentation allows each path to be optimized for its specific function, improving overall airflow efficiency while maintaining manageable structural complexity through modular design
Solution Approach 2:
The outer air path acts as an intermediary cooling system that circulates air around the heating element to remove excess heat before it can be lost to the environment. This intermediary cooling mechanism improves energy efficiency by recovering heat that would otherwise be wasted, while the modular air path design keeps the structural complexity manageable
3Productivity
If air is directed through the article, then aerosol generation is enhanced, but the device structure becomes more complex
Solution Approach 1:
The air path is segmented into two distinct pathways: an inner air path that delivers air directly through the article, and an outer air path that provides cooling air around the heating element. This segmentation allows each path to be optimized for its specific function, improving overall airflow efficiency while maintaining manageable structural complexity through modular design
