Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems face challenges in efficiently delivering aerosol while maintaining a suitable temperature and flavor profile, particularly in non-combustible systems where aerosol generation is achieved through heating without combustion.
Innovation Solution
A component for an aerosol provision system is developed, featuring a body of crimped sheet material wrapped with a plug wrap having an adhesive pattern that spans at least 40% of the plug wrap's width, enhancing adhesion and aerosol delivery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plug wrap is used to wrap the body of material, then adhesion strength is improved, but aerosol delivery efficiency deteriorates due to increased pressure drop
Solution Approach 1:
The adhesive pattern is applied locally to specific regions of the plug wrap rather than covering the entire surface. The adhesive spans at least 40% of the width of the longitudinal sheet of plug wrap, creating zones of varying adhesion strength that balance attachment needs with aerosol flow requirements.
Solution Approach 2:
Instead of applying adhesive across the full width of the plug wrap, the adhesive is applied partially across at least 40% of the width. This partial application provides sufficient adhesion to prevent detachment while leaving gaps that reduce pressure drop and improve aerosol delivery efficiency.
2Strength
If adhesive pattern spans wider area, then adhesion strength is improved, but pressure drop increases reducing aerosol delivery
Solution Approach 1:
The adhesive pattern creates local zones of high adhesion strength where needed for attachment, while leaving other areas with lower adhesion to maintain open pathways for aerosol flow, thereby reducing overall pressure drop.
Solution Approach 2:
The adhesive pattern spans at least 40% of the width of the plug wrap, providing partial coverage that achieves sufficient adhesion without completely sealing the structure, thus balancing attachment strength with pressure drop reduction.
