Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid or supercritical carbon dioxide is used to extract fluorinated ether compounds, then extraction can be performed, but extraction efficiency is insufficient
Solution Approach 1:
The patent changes the fundamental parameter of the extracting medium from carbon dioxide (supercritical or liquid state) to fluorinated organic solvents. This parameter change enables selective extraction of fluorinated ether compounds based on their specific molecular structures (formulas A1-A3 and B1-B2), thereby resolving the contradiction between extraction efficiency and effectiveness by matching solvent properties with target compound characteristics.
Solution Approach 2:
The patent introduces fluorinated organic solvents as intermediary substances that mediate between the fluorinated ether compounds and the extraction process. These solvents act as selective intermediaries that preferentially dissolve and separate the desired fluorinated ether compounds from other components, improving both extraction efficiency and reliability through selective interaction.
2Productivity
If conventional extraction methods are used, then extraction process can be completed, but desired fluorinated ether compound cannot be efficiently extracted
Solution Approach 1:
The patent applies local quality by designing extraction systems tailored to specific fluorinated ether compound structures. Different fluorinated organic solvents are selected based on the specific molecular characteristics (formulas A1-A3 and B1-B2) of the target compounds, creating localized optimization for each extraction scenario. This ensures both high extraction speed and precise selectivity for the desired compounds.
Solution Approach 2:
The patent changes the chemical composition parameters of the extracting medium to fluorinated organic solvents with specific molecular structures that match the target fluorinated ether compounds. This parameter change enables simultaneous achievement of high extraction speed and precise selectivity by optimizing solvent-compound interactions.
