Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If compounds are isolated from Antrodia camphorata using traditional extraction methods, then various compounds including triterpenoids can be obtained, but further experimentation is required to identify effective anti-tumor compounds
Solution Approach 1:
The patent segments the extraction process into multiple sequential steps using different solvents (ethanol extraction followed by dichloromethane/water extraction) to separate compounds into different fractions. This systematic segmentation allows identification of active anti-tumor compounds in specific fractions (ANCA-E-D-2 and ANCA-E-D-3) without requiring exhaustive testing of all extracted compounds
Solution Approach 2:
The patent applies extraction principles by using ethanol solution to extract compounds from Antrodia camphorata, followed by dichloromethane/water extraction to separate the extract into organic and aqueous layers. This progressive extraction isolates the active anti-tumor compounds from the complex mixture of substances in the mushroom
2Reliability
If multiple extraction steps are performed to purify compounds, then effective anti-tumor fractions can be identified, but the extraction process becomes more complex
Solution Approach 1:
The extraction process is divided into distinct segmentation steps: first ethanol extraction to obtain crude extract, then dichloromethane/water extraction to separate into organic layer (ANCA-E-D) and aqueous layer, followed by further fractionation into ANCA-E-D-1 through ANCA-E-D-4. This segmentation identifies reliable anti-tumor active fractions while maintaining procedural organization
Solution Approach 2:
The patent uses dichloromethane as an intermediary solvent to facilitate separation of compounds based on their solubility characteristics. The dichloromethane/water extraction acts as an intermediary step that partitions compounds between organic and aqueous phases, enabling subsequent identification of active fractions
