Low-Viscosity Aerosolisable Material for High Cannabinoid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol delivery systems face challenges in formulating aerosolisable materials to produce high cannabinoid content aerosols efficiently, as higher cannabinoid concentrations are expected to yield higher masses per puff.
Innovation Solution
Aerosolisable materials with a viscosity of less than 500cP and up to 45%w/w cannabinoid content are used, combined with a heater providing 4W to 8W power output, to generate aerosols with higher cannabinoid mass per puff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If aerosolisable materials with higher cannabinoid concentrations are formulated to increase cannabinoid mass per puff, then the expected cannabinoid delivery increases, but the viscosity increases making atomization difficult
Solution Approach 1:
The patent changes the physical-chemical parameters of the aerosolisable material by limiting viscosity to less than 500cP while optimizing cannabinoid content to up to 45%w/w. This parameter optimization allows the material to maintain both low viscosity for easy atomization and high cannabinoid content for effective delivery, resolving the contradiction between these two properties.
Solution Approach 2:
The patent uses composite aerosolisable materials containing cannabinoids combined with other substances (such as carrier oils or terpenes) that maintain the overall viscosity below 500cP while achieving up to 45%w/w cannabinoid content. This composite formulation enables simultaneous achievement of low viscosity and high cannabinoid concentration.
2Ease of operation
If aerosolisable materials with lower viscosity are used to improve atomization, then atomization efficiency increases, but cannabinoid content must be reduced
Solution Approach 1:
The patent establishes specific parameter ranges - viscosity less than 500cP and cannabinoid content up to 45%w/w - that simultaneously optimize both atomization efficiency and cannabinoid delivery. This parameter optimization resolves the contradiction by showing that low viscosity and high cannabinoid content are not mutually exclusive when properly formulated.

Function Achieved in This Case
The described aerosolisable materials enable the production of aerosols with cannabinoid masses per puff that are higher than expected, achieving totals of 2mg/puff or greater, surprising given the lower cannabinoid concentration.
Implementation Method 1
an aerosol generator which is capable of converting an aerosolisable material into an aerosol. In some instances, the aerosol generated is a condensation aerosol whereby an aerosolisable material is heated to form a vapor which is then allowed to condense into an aerosol
Implementation Method 2
an aerosol generated is a condensation aerosol whereby an aerosolisable material is heated to form a vapor which is then allowed to condense into an aerosol
Implementation Method 3
such atomization may be brought about mechanically, e.g. by subjecting the aerosolisable material to vibrations so as to form small particles of material that are entrained in airflow
