Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional chemical extraction methods are used to extract bioactive ingredients from cannabis, then the extraction process can be completed, but chemical residues remain in the extract causing impurity

Engineering Contradiction:

Improveextraction rateVSAvoidchemical residue

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent employs supercritical carbon dioxide as the extraction solvent, utilizing carbon dioxide in its supercritical state. Carbon dioxide is inert, non-toxic, and leaves no harmful residues after extraction. The supercritical fluid extracts bioactive ingredients efficiently, then returns to gaseous state, leaving pure extract without chemical contamination.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The patent uses supercritical carbon dioxide which can be easily separated from the extract and reused. The carbon dioxide is recovered by reducing pressure and temperature, returning to gaseous state, and can be condensed and reused for subsequent extraction cycles, eliminating waste and reducing costs.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Ease of manufacture

If dried cannabis material is used as raw material for extraction, then the material is easy to handle, but most active ingredients are lost

Engineering Contradiction:

Improvematerial handlingVSAvoidactive ingredient retention

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent performs extraction on fresh cannabis material before drying occurs. By extracting while the plant material is still fresh and contains high levels of moisture and active ingredients, the method captures the full spectrum of bioactive compounds including water-soluble constituents that would be lost or degraded in dried material.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent utilizes supercritical fluid conditions (high pressure and temperature) to enhance extraction efficiency from fresh material. The supercritical state of carbon dioxide allows it to penetrate fresh plant tissue effectively, extracting both water-soluble and fat-soluble components, then returns to gaseous state by changing pressure and temperature parameters.

Inventive Principle:

Principle #35Parameter changes
