Drying-Agent Consumable for Consistent Aerosol Volatile Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol deposition on substrate materials in aerosol provision systems leads to inconsistent volatile compound delivery and negatively impacts the user experience, particularly in systems with tobacco-based substrates, due to the formation of large liquid droplets that affect sensory perception.
Innovation Solution
Incorporating a drying agent, such as a desiccant or wicking material, in proximity to the substrate material within the consumable to reduce aerosol deposition and maintain consistent volatile compound delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If substrate material is used in aerosol provision system, then volatile compound delivery is achieved, but aerosol deposition occurs leading to inconsistent delivery
Solution Approach 1:
A drying agent is introduced as an intermediary substance between the aerosol generation chamber and the substrate material. This drying agent absorbs excess moisture from the aerosol before it contacts the substrate, preventing liquid droplet formation and deposition on the substrate surface, thereby maintaining consistent volatile compound delivery
Solution Approach 2:
The humidity parameter of the aerosol is changed by introducing a drying agent that modifies the aerosol composition. By reducing the moisture content of the aerosol through interaction with the drying agent, the system prevents condensation and deposition on the substrate, ensuring reliable volatile delivery
2Reliability
If drying agent is added to reduce aerosol deposition, then delivery consistency improves, but device complexity increases
Solution Approach 1:
The drying agent is combined with the substrate material in a single consumable component. This merging of functions (substrate material for volatile delivery and drying agent for moisture control) into one integrated unit reduces device complexity by eliminating the need for separate drying mechanisms while maintaining delivery consistency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The use of a drying agent improves the consistency of volatile compound delivery and reduces aerosol deposits, enhancing the user experience by preventing the formation of large liquid droplets in aerosol provision systems.
Implementation Method 1
The at least one drying agent may include a sorbent. The sorbent may be a desiccant, a wicking material, or a mixture thereof.
Implementation Method 2
The sorbent may be a desiccant, a wicking material, or a mixture thereof. When the sorbent is a desiccant or mixture thereof, it may be selected from the group consisting of an anhydrous inorganic salt, a superabsorbent polymer (SAP), silica, or a mixture thereof.
Implementation Method 3
The sorbent may be a desiccant, a wicking material, or a mixture thereof.

AI summary
A consumable for an aerosol provision system comprising at least one substrate material in proximity to at least one drying agent. The drying agent preferably includes a sorbent, e.g., a desiccant, a wicking material or a mixture thereof. Also provided is a pod for an aerosol provision system where the pod contains the consumable and the consumable is configured to receive an aerosol, and use of a drying agent to increase consistency or yield of volatile compound delivery from a substrate material in an aerosol provision system.
