Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods are used for cannabinoids, curcuminoids, and ginsenosides, then extraction can be performed with simple equipment, but the extraction efficiency is low and the process is costly
Solution Approach 1:
The plant material is frozen before extraction, which preliminary prepares the cellular structure for more efficient compound release during the extraction process, thereby improving extraction efficiency without requiring complex equipment
Solution Approach 2:
The extraction process utilizes phase transitions by changing temperature parameters (freezing followed by controlled heating during extraction) to enhance the release and extraction of phytochemicals, improving efficiency while maintaining a relatively simple process framework
2Stability of the object's composition
If conventional extraction solvents are used, then the extraction process is simple, but the extracted phytochemicals lack chemical stability and may be toxic
Solution Approach 1:
The extraction process uses controlled temperature parameters and phase transitions (freezing, controlled heating, evaporation) to preserve the chemical stability of phytochemicals while maintaining a relatively simple extraction setup without requiring complex stabilization equipment
Solution Approach 2:
The process replaces harsh chemical solvents with a controlled physical extraction system using phase transitions and enzymatic action, eliminating toxicity concerns while maintaining chemical stability through physical rather than chemical means
3Stability of the object's composition
If conventional drying methods are used, then the process is simple and quick, but the phytochemicals lose chemical stability and bioactivity
Solution Approach 1:
The process utilizes controlled phase transitions including freezing and controlled evaporation to remove water while preserving phytochemical stability, achieving both stability and reasonable processing time without requiring complex drying equipment
Solution Approach 2:
The plant material is frozen before extraction and drying, which preliminary prepares the structure for more efficient water removal while protecting phytochemicals from degradation during the drying process, reducing both time and stability loss
4Productivity
If non-organic extraction methods are used, then the extraction efficiency is high, but the process is toxic and not environmentally sustainable
Solution Approach 1:
The process replaces toxic chemical solvents with a physical extraction system based on phase transitions, freezing, and controlled evaporation, achieving high extraction efficiency while eliminating toxicity and environmental harm
Solution Approach 2:
The freezing and phase transition process allows the plant material itself to facilitate the extraction through natural physical changes, eliminating the need for toxic external chemicals while maintaining high extraction efficiency
