Solution Overview
Problem
In induction heating type smoking devices, ensuring a gas flow path while supporting the susceptor and aerosol-forming substrate is challenging, as existing designs often obstruct airflow, affecting the efficiency of aerosol generation and flavor distribution.
Innovation Solution
A smoking device cartridge design featuring a support member with a gap between itself and the packaging member, allowing for airflow while securely holding the susceptor and aerosol-forming substrate, ensuring efficient gas flow and aerosol generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support member is added to hold the susceptor and aerosol-forming substrate, then structural stability is improved, but gas flow path is obstructed
Solution Approach 1:
The support member is designed as a thin-walled cylindrical structure that provides structural support while maintaining gas permeability. The thin wall design allows gas to pass through the support member, preventing flow obstruction while still providing the necessary mechanical support for the susceptor and aerosol-forming substrate.
Solution Approach 2:
The support member incorporates a porous structure that enables gas flow through its body. This porous design allows the support member to simultaneously provide structural stability and maintain unobstructed gas flow paths, resolving the contradiction between support function and flow efficiency.
2Strength
If the support member contacts the packaging member tightly, then structural support is improved, but gas flow path is blocked
Solution Approach 1:
The invention extracts the gas flow function from the contact interface between the support member and packaging member. By designing the support member with a through-hole structure, the gas flow path is separated from the structural support function, allowing tight contact for support while maintaining open flow paths through the holes.
Solution Approach 2:
The support member introduces additional dimensional features (through-holes) that create three-dimensional gas flow paths. This dimensional addition allows the support member to maintain structural contact with the packaging member while providing multiple pathways for gas flow, preventing blockage.
