Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If catalyst precursors are combined in a recycled organic reaction solvent to form catalyst compounds, then productivity and waste reduction are improved, but separation complexity and energy consumption increase
Solution Approach 1:
The patent utilizes phase transition of the organic reaction solvent through vaporization and condensation to achieve separation and recycling. The solvent is vaporized from the catalyst compound mixture, then condensed back to liquid form for reuse, effectively separating the solvent from the catalyst compound while enabling solvent recycling without complex separation equipment
Solution Approach 2:
The patent extracts the organic reaction solvent from the catalyst compound mixture through vaporization. By selectively removing the solvent phase from the reaction mixture, the process enables catalyst compound isolation and solvent recovery in a simple manner, resolving the separation complexity issue
2Loss of substance
If solvent is vaporized and condensed for recycling, then loss of substance is reduced, but use of energy increases
Solution Approach 1:
The patent implements solvent recovery by vaporizing the solvent from the catalyst compound mixture and then condensing it back to liquid form for reuse. This discarding of solvent from the reaction mixture followed by recovery through condensation prevents solvent loss and enables continuous recycling, directly addressing the substance loss issue while managing energy consumption
