Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of therapeutic cannabinoids from cannabis often involves prolonged heating, which leads to undesirable side products and degradation of molecules like terpenes, resulting in suboptimal pharmacological effects and product quality.
Innovation Solution
A method involving a composition of tetrahydrocannabinol and a non-volatile molecule in a liquid phase, where energy is applied to convert tetrahydrocannabinol into vaporized form without vaporizing the non-volatile molecule, followed by separation and condensation using a heat sink to produce a liquid distillate with controlled molar ratios of tetrahydrocannabinol and cannabinol, ensuring high purity and minimal side product formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prolonged heating is used to convert THCA to THC, then decarboxylation is achieved, but undesirable side products are formed and molecule degradation occurs
Solution Approach 1:
The patent utilizes phase transition (vaporization and condensation) to separate THC from non-volatile impurities. By vaporizing THC at controlled temperatures and condensing it separately from non-volatile molecules, the process achieves complete decarboxylation without forming side products, as the vaporization step occurs before unwanted chemical reactions can proceed.
Solution Approach 2:
The patent replaces prolonged thermal heating with a controlled vaporization-condensation process. Instead of using extended heating time to drive decarboxylation, the system uses a brief controlled vaporization step followed by immediate condensation, substituting the mechanical/thermal process with a phase-change-based separation mechanism that achieves the same chemical transformation without the harmful side effects of prolonged heating.
2Reliability
If prolonged heating is used to produce CBD from CBDA, then decarboxylation is achieved, but CBN and other side products are formed
Solution Approach 1:
The patent applies phase transition to separate CBD from non-volatile impurities and prevent CBN formation. By vaporizing CBD at controlled temperatures and immediately condensing it, the process achieves complete decarboxylation of CBDA without allowing the oxidation and decomposition reactions that lead to CBN formation during prolonged heating.
Solution Approach 2:
The patent substitutes prolonged thermal heating with a controlled vaporization-condensation cycle. This replacement mechanism achieves decarboxylation through the phase change process itself, which occurs rapidly and completely without the extended thermal exposure required to produce CBN and other degradation products.
3Reliability
If prolonged heating is used for decarboxylation, then cannabinoid conversion is achieved, but terpenes and other molecules are degraded and vaporized
Solution Approach 1:
The patent uses phase transition to selectively vaporize only the cannabinoid compounds while leaving non-volatile molecules behind. By controlling the vaporization temperature and timing, the process achieves complete cannabinoid decarboxylation without vaporizing or degrading terpenes and other volatile molecules, as they are not subjected to prolonged heating.
Solution Approach 2:
The patent replaces prolonged heating with a controlled vaporization-condensation process that targets only the cannabinoid fraction. This substitution allows selective vaporization of cannabinoids at controlled temperatures without the thermal degradation that affects terpenes and other molecules during extended heating periods.
4Productivity
If conventional decarboxylation methods are used, then THC and CBD are produced, but product purity is reduced due to side products
Solution Approach 1:
The patent employs phase transition to achieve both high productivity and high purity. By vaporizing cannabinoids and condensing them separately from non-volatile impurities, the process produces pure THC and CBD without side products, achieving both efficient cannabinoid conversion and high product purity simultaneously through the physical separation mechanism.
Solution Approach 2:
The patent substitutes conventional heating methods with a vaporization-condensation system that inherently separates products from impurities. This replacement mechanism achieves both high cannabinoid production efficiency and high purity by using the physical properties of vaporization to separate desired products from unwanted side products and non-volatile contaminants.
