Solution Overview

Problem

Existing methods for extracting nicotine from tobacco using harsh chemicals like ammonium hydroxide and sulfuric acid are environmentally unfriendly, require extensive purification, and may extract undesirable compounds, necessitating a more efficient and cleaner extraction process.

Innovation Solution

A method involving hydrated ionic clay and tobacco material is used to extract nicotine directly into a humectant solution, avoiding harsh chemicals and high temperatures, by forming a composition with hydrated ionic clay and tobacco, which is then mixed with a solvent to extract nicotine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If harsh chemicals (ammonium hydroxide, naphtha, gasoline, sulfuric acid) are used for nicotine extraction, then extraction efficiency is improved, but environmental friendliness deteriorates and extensive purification is required

Engineering Contradiction:

Improveextraction efficiencyVSAvoidenvironmental friendliness

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces supercritical carbon dioxide as an intermediary extraction medium that replaces harsh chemicals. CO2 acts as a mediator between the tobacco material and nicotine, providing efficient extraction while being environmentally benign and requiring no extensive purification, thus resolving the contradiction between extraction efficiency and environmental friendliness

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical parameters of carbon dioxide by applying high pressure and temperature to achieve supercritical state, which enables efficient extraction. By adjusting these parameters, the extraction efficiency is improved while avoiding the use of harmful chemicals, thus resolving the contradiction

Inventive Principle:

Principle #35Parameter changes

2Productivity

If harsh chemicals are used for nicotine extraction, then extraction efficiency is improved, but the complexity of purification processes increases

Engineering Contradiction:

Improveextraction efficiencyVSAvoidpurification process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Supercritical CO2 serves as a clean intermediary that extracts nicotine without leaving harmful residues, thereby eliminating the need for complex purification steps while maintaining high extraction efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes the property of CO2 to revert to gaseous state after extraction, allowing for easy separation and recovery of nicotine without complex purification processes. The CO2 can be discarded or recovered in its gaseous form, simplifying the overall process

Inventive Principle:

Principle #34Discarding and recovering

3Quantity of substance

If large amount of vaporizable material is vaporized, then desired nicotine effect is achieved, but the volume of material required increases

Engineering Contradiction:

Improvenicotine effectVSAvoidvaporizable material volume

Core Design Contradiction:

Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The patent extracts and concentrates nicotine from tobacco material using supercritical CO2, isolating the active ingredient in a concentrated form. This allows for achieving the desired nicotine effect with a smaller volume of vaporizable material, as the nicotine is delivered in a concentrated state rather than requiring large volumes of diluted plant material

Inventive Principle:

Principle #2Taking out (Extraction)
