Multi-Material Aerosol Substrate for Consistent Flavor Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol delivery devices face challenges in providing consistent aerosol release and flavor sensations, as they often rely on single aerosol formers with inconsistent performance characteristics, leading to variable flavor release and inadequate loading of aerosol forming materials.
Innovation Solution
The use of a substrate impregnated with two or more aerosol forming materials, such as glycerol and propylene glycol, with different boiling points and vapor pressures, to control the release of aerosol over time, along with additional materials like polysorbates and fatty acids, to enhance consistency and flavor delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single aerosol former is used in the substrate, then the device structure is simple, but the aerosol release is inconsistent and performance characteristics are variable
Solution Approach 1:
The patent applies composite materials by combining multiple aerosol formers (e.g., glycerol and propylene glycol) in the substrate at specific ratios. This composite approach ensures consistent aerosol release performance by leveraging the complementary properties of each component, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent utilizes parameter changes by selecting aerosol formers with different boiling points and vapor pressures. By controlling the release based on these physical parameters during heating, the system achieves consistent aerosol performance while managing the complexity through scientifically grounded material selection.
2Duration of action of moving object
If multiple aerosol formers with different boiling points are used, then controlled release over time is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-calculating and optimizing the ratios of multiple aerosol formers before substrate impregnation. This advance preparation ensures controlled release duration without complicating the actual manufacturing process, as the formulation is established prior to production.
3Quantity of substance
If aerosol formers are loaded at higher concentrations, then flavor delivery is enhanced, but the loading capacity of the substrate becomes inadequate
Solution Approach 1:
The patent applies parameter changes by optimizing the concentration ratios of multiple aerosol formers in the substrate. By adjusting these parameters within specific ranges (e.g., glycerol to propylene glycol ratios), the system achieves both adequate loading capacity and consistent flavor release, resolving the contradiction between quantity and reliability.
