Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems for tobacco products face challenges in managing the temperature of the aerosol and the mouthpiece, particularly due to the use of aerosol-former materials that can increase the aerosol mass and maintain a higher temperature, leading to an undesirable mouthpiece temperature.
Innovation Solution
A component for an aerosol provision system is designed with a tubular body made of cellulose-based material sandwiched between inner and outer sheet materials, where the inner sheet material has a high permeability of at least 200 CU, facilitating heat transfer and moisture absorption to cool the aerosol and reduce the mouthpiece temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If aerosol-former materials are used to increase aerosol mass, then aerosol generation is improved, but mouthpiece temperature increases to an undesirable level
Solution Approach 1:
The patent introduces a cooling component as an intermediary element between the aerosol generation source and the mouthpiece. This component actively mediates the thermal interaction by providing a cooling effect that counteracts the heat generated by aerosol-former materials, thus resolving the contradiction between increasing aerosol mass and controlling mouthpiece temperature.
Solution Approach 2:
The patent changes the thermal parameters of the delivery system by incorporating cooling mechanisms that alter the temperature profile of the aerosol and mouthpiece. This parameter change allows the system to maintain higher aerosol mass while keeping mouthpiece temperature within acceptable ranges through active thermal management.
2Temperature
If high permeability sheet material is used, then heat transfer and moisture absorption are improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs porous sheet materials with high permeability (at least 200 CU) as a core component of the cooling system. These porous materials naturally provide heat transfer and moisture absorption functions through their structure, eliminating the need for complex active cooling mechanisms while achieving the desired thermal management performance.
