Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering cannabinoids, such as smoking articles and e-cigarettes, face limitations in solubility and efficiency, particularly with cannabinoids like CBD, which can result in low delivery levels due to limited solubility in liquid vaping systems.
Innovation Solution
A composition comprising 1-50 wt% cannabinoids, 5-30 wt% aerosol-former material, 1-30 wt% terpenes, and a gelling agent, which forms an aerosol-generating material that can be used in non-combustible aerosol provision systems, allowing for higher cannabinoid delivery when heated or energized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid vaping systems are used to deliver cannabinoids, then the delivery mechanism is simple, but the cannabinoid delivery level is low due to limited solubility
Solution Approach 1:
The patent changes the physical state of the delivery system from liquid to solid aerosol-generating material. This parameter change allows cannabinoids to be incorporated at higher concentrations (1-50 wt%) in a solid matrix that can be heated to generate aerosol, overcoming the solubility limitations of liquid vaping systems while maintaining effective delivery
Solution Approach 2:
The patent creates a composite aerosol-generating material comprising cannabinoids (1-50 wt%), aerosol-former material (5-30 wt%), and terpenes (1-30 wt%). This composite structure allows the cannabinoids to be dispersed in a solid matrix that facilitates aerosol generation, solving both the solubility and delivery level issues simultaneously
2Productivity
If more aerosol-former material is used to improve aerosol generation, then aerosol formation is enhanced, but the cannabinoid concentration in the aerosol decreases
Solution Approach 1:
The patent reduces the aerosol-former material content to a controlled range (5-30 wt%) in the solid composition, which is lower than typical liquid vaping formulations. This parameter optimization ensures sufficient aerosol generation while maintaining high cannabinoid concentration (1-50 wt%) in the final aerosol product
Solution Approach 2:
The patent develops a balanced composite formulation where cannabinoids (1-50 wt%), aerosol-former material (5-30 wt%), and terpenes (1-30 wt%) work synergistically. The terpenes enhance aerosol formation efficiency, allowing reduced aerosol-former material content while maintaining both aerosol generation efficiency and cannabinoid concentration
3Quantity of substance
If higher cannabinoid levels are incorporated into the composition, then delivery potential increases, but solubility and formulation stability become problematic
Solution Approach 1:
The patent transitions from liquid to solid formulation, allowing cannabinoid incorporation at 1-50 wt% levels. The solid matrix provides structural stability that prevents the solubility and phase separation issues encountered in liquid systems, enabling high cannabinoid content while maintaining formulation stability
Solution Approach 2:
The patent creates a stable composite where cannabinoids are dispersed in a solid matrix containing aerosol-former material (5-30 wt%) and terpenes (1-30 wt%). This composite structure maintains physical and chemical stability while accommodating high cannabinoid loads, overcoming the formulation stability limitations of liquid vaping systems
