Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustible aerosol provision systems face challenges in maintaining consistent aerosol generation and user experience due to issues with aerosol-generating material displacement and packing density during the insertion of aerosol generators, leading to inconsistent aerosol production and user difficulty in using the devices.
Innovation Solution
The proposed solution involves an article for a non-combustible aerosol provision system comprising an aerosol-generating section with strands or strips of aerosol-generating material enclosed by a moisture-impermeable wrapper and a cooling section with a hollow channel, designed to reduce aerosol-generating material displacement and enhance consistent packing density, facilitating easier insertion of aerosol generators and improved aerosol generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aerosol-generating material is placed in the aerosol-generating section, then aerosol can be generated, but the material displaces during insertion of aerosol generators leading to inconsistent packing density
Solution Approach 1:
The article is divided into distinct functional sections: an aerosol-generating section containing the material and a cooling section with a hollow channel. This segmentation allows the material to be contained and positioned separately from the cooling mechanism, preventing displacement during insertion while maintaining consistent packing density in the aerosol-generating section.
Solution Approach 2:
The aerosol-generating material is nested within the aerosol-generating section, which itself is nested within the overall article structure alongside the cooling section. This nested arrangement ensures the material remains securely positioned during device assembly and insertion, eliminating displacement issues while maintaining reliable aerosol generation.
2Temperature
If a cooling section is added to the mouthpiece, then aerosol cooling is improved, but the device complexity increases
Solution Approach 1:
The cooling section incorporates a hollow channel that allows aerosol to pass through, providing cooling functionality. This design achieves temperature reduction without requiring complex multi-component structures, as the hollow channel itself serves as the cooling pathway while maintaining relatively simple device architecture.
3Productivity
If the hollow channel diameter is between 1 mm and 4 mm, then aerosol flow is optimized, but the manufacturing precision requirements increase
Solution Approach 1:
The hollow channel diameter is specified within a range of 1 mm to 4 mm, providing flexibility in manufacturing while optimizing aerosol flow characteristics. This parameter specification allows manufacturers to achieve efficient aerosol generation without requiring extremely tight tolerances, balancing productivity with manufacturability.

AI summary
An article for use in a non-combustible aerosol provision system includes an aerosol-generating section with a plurality of strands and/or strips of aerosol-generating material. The aerosol-generating section is circumscribed by a moisture impermeable wrapper and a cooling section is provided directly adjacent to the aerosol-generating section. The cooling section can have at least one of a hollow channel having an internal diameter of between about 1 mm and about 4 mm or a maximum of 32% of the cross-sectional area of the cooling section being a hollow channel. A non-combustible aerosol provision system is also described.
