Aerosol Material Delivery Layout for Flexible Composition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol delivery systems lack flexibility in controlling the aerosol composition and delivery of sensory materials, such as flavoring and additives, which are often ineffective at different environmental/temperature conditions.
Innovation Solution
A material delivery system with first and second capillary materials of varying porosities is used to transport aerosol-generating or sensory materials, allowing independent control and delivery of different materials, including a compressible reservoir to displace materials towards the flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single reservoir and single capillary material are used, then the device structure is simple, but the flexibility to control aerosol composition and delivery of sensory materials is limited
Solution Approach 1:
The invention divides the material delivery system into multiple segments: a first reservoir for aerosol-generating material and a second reservoir for sensory material, each with its own capillary material. This segmentation allows independent control and optimization of each material's delivery, enabling flexible aerosol composition control while maintaining a modular, manageable structure.
Solution Approach 2:
The second reservoir containing sensory material is positioned within or adjacent to the first reservoir structure. The capillary materials are arranged concentrically or in nested configurations, allowing both materials to be delivered through an integrated structure that appears simple externally but provides complex functional control internally.
2Manufacturing precision
If capillary material with uniform porosity is used, then the manufacturing process is simple, but the control over material transport and aerosol generation is insufficient
Solution Approach 1:
The invention employs capillary materials with non-uniform porosity distribution, where different regions of the capillary material have different pore sizes and densities. The region closer to the reservoir has higher porosity for efficient material uptake, while the region closer to the flow path has lower porosity for controlled release. This local variation in quality enables precise control over material transport rates and aerosol generation characteristics.
Solution Approach 2:
The capillary material's porosity parameter is deliberately varied along its length to optimize performance. By changing the porosity parameter from high near the reservoir to low near the flow path, the system achieves controlled material transport and aerosol generation without requiring complex external control mechanisms, balancing manufacturing simplicity with functional precision.
3Reliability
If sensory materials are delivered without temperature control, then the system is simple, but the delivery effectiveness varies at different environmental conditions
Solution Approach 1:
The invention incorporates a heating element that can dynamically adjust the temperature of the sensory material in the second reservoir. This dynamic temperature control allows the system to maintain optimal delivery effectiveness across varying environmental conditions by compensating for temperature changes, ensuring consistent sensory material vaporization and aerosol formation regardless of external temperature variations.
