Aerosol Generation Device Cross-Flow Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustion-type aerosol generation devices face challenges in delivering liquefied aerosol through internal air passages without obstruction, affecting airflow and aerosol delivery.
Innovation Solution
The aerosol generation device features a mainstream smoke passage that extends in a direction crossing the longitudinal direction of the cigarette, with inclined or rounded surfaces at connecting portions to prevent aerosol stagnation, ensuring smooth aerosol flow and heating for efficient delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mainstream smoke passage extends in the longitudinal direction of the cigarette, then the structure is simple, but the aerosol may get stuck in the air path
Solution Approach 1:
The mainstream smoke passage transitions from a single longitudinal direction to a multi-directional configuration by extending in both the longitudinal direction and a direction crossing the longitudinal direction. This dimensional change creates a three-dimensional airflow path that prevents aerosol stagnation while maintaining structural integration.
Solution Approach 2:
Rounded surfaces are formed at connecting portions between different segments of the mainstream smoke passage. These curved transitions eliminate sharp angles that could cause aerosol accumulation, ensuring smooth airflow while maintaining passage connectivity.
2Reliability
If the mainstream smoke passage includes multiple directions, then aerosol flow is improved, but the device complexity increases
Solution Approach 1:
Multiple segments of the mainstream smoke passage are merged into a single integrated structure that performs both airflow guidance and aerosol delivery functions. The connecting portions with rounded surfaces serve dual purposes as both structural transitions and aerosol flow channels, reducing the need for separate components.
Solution Approach 2:
The mainstream smoke passage is designed to simultaneously achieve multiple functions: guiding airflow, delivering aerosol, preventing stagnation, and maintaining structural integrity. This multi-functionality reduces the overall device complexity by eliminating the need for separate components for each function.
