Aerosol Article Support Ribs for Stable Heating Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices face issues with irregular deformation of the aerosol generating article's cross-section due to heat application, leading to inconsistent delivery of components, air flow path irregularities, and variable insertion alignment, which affects smoking taste and atomization.
Innovation Solution
An aerosol generating device with a support structure featuring ribs along the cavity's circumference to align and fix the aerosol generating article's position, maintaining a consistent cross-sectional shape and preventing unwanted airflow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat is applied to the aerosol generating article to generate aerosol, then aerosol generation is enabled, but the cross-section shape of the article deforms irregularly over time
Solution Approach 1:
The patent applies a heat-resistant film to wrap around the aerosol generating article, providing mechanical support to maintain the cross-sectional shape while allowing heat to pass through for aerosol generation. This flexible shell structure prevents deformation without blocking the thermal process.
2Ease of operation
If the aerosol generating article is inserted into the device, then aerosol generation is enabled, but the insertion alignment varies causing inconsistent delivery amount
Solution Approach 1:
The patent introduces asymmetric guide structures including a guide groove on the article surface and a corresponding guide protrusion on the holder. This asymmetric design ensures that the article can only be inserted in the correct orientation, achieving precise alignment while maintaining ease of operation through the guiding mechanism.
3Ease of operation
If the aerosol generating article is held in the holder, then aerosol generation is enabled, but gaps form between the article and device creating unexpected airflow paths
Solution Approach 1:
The heat-resistant film extends to cover the gap between the aerosol generating article and the holder, sealing the unexpected airflow path. This flexible film maintains the holding stability while preventing air leakage that would compromise airflow consistency.
4Shape
If the cross-section shape is maintained constant, then consistent aerosol delivery is achieved, but the article may adhere to lips and be unintentionally pulled out
Solution Approach 1:
The heat-resistant film provides a smooth outer surface that reduces adhesion to lips, preventing the article from being unintentionally pulled out while maintaining the cross-sectional shape stability for consistent aerosol delivery.
