Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current combustible aerosol provision systems face challenges in optimizing the crimp pattern and density of sheet materials used in components, which affect pressure drop and aerosol delivery, leading to suboptimal performance in terms of flavor and compound passage.
Innovation Solution
A component for combustible aerosol provision systems featuring crimped sheet material with a crimp pattern of substantially parallel ridges and grooves, where the average spacing between ridges is greater than 0.3 mm and the crimp amplitude is less than 0.7 mm, resulting in a body material density between 0.1 and 0.25 mg/mm³, enhancing aerosol passage and reducing pressure drop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the crimp pattern density is increased (smaller spacing between ridges), then the filtration capability is improved, but the pressure drop increases and aerosol delivery is reduced
Solution Approach 1:
The patent applies parameter changes by optimizing the crimp pattern geometry (spacing between ridges, crimp amplitude) and the body material density to achieve a balance between filtration capability and aerosol delivery. Specific parameters are controlled within defined ranges to resolve the contradiction between these two performance aspects.
2Strength
If the body material density is increased, then the structural integrity is improved, but the pressure drop increases and aerosol passage is restricted
Solution Approach 1:
The patent resolves this contradiction by precisely controlling the body material density within a specific range (0.08-0.25 mg/mm³) and optimizing the crimp pattern parameters. This parameter optimization ensures that the material maintains sufficient structural integrity while allowing adequate aerosol passage with minimal pressure drop.
3Quantity of substance
If the crimp amplitude is increased, then the surface area for aerosol interaction is improved, but the pressure drop increases
Solution Approach 1:
The patent applies parameter changes by optimizing the crimp amplitude within a defined range (0.3-0.7 mm) to maximize the surface area for aerosol interaction while maintaining acceptable pressure drop levels. This controlled parameter adjustment resolves the contradiction between compound passage and pressure drop.
