Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If in-situ growth method is used, then operation simplicity is improved, but production time increases and production efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-modifying the substrate surface with organic groups before the actual metal-organic framework growth. This pre-treatment step enables faster subsequent growth while maintaining operational simplicity, thus resolving the contradiction between ease of operation and production efficiency.
Solution Approach 2:
The patent uses organic groups as an intermediary substance that facilitates the interaction between the substrate and metal ions. This intermediary enables controlled and accelerated framework formation, improving production efficiency while keeping the process simple to operate.
2Manufacturing precision
If LBL deposition method is used, then product purity is improved, but processing time increases and production efficiency decreases
Solution Approach 1:
The patent merges the advantages of LBL deposition (high purity) with in-situ growth (simplicity) by combining surface pre-modification with subsequent metal-organic framework growth in a unified process. This achieves high purity products with reduced processing time, resolving the contradiction between manufacturing precision and productivity.
3Reliability
If crystal-seed method is used, then membrane defect reduction is improved, but production time increases and production efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-modifying the substrate surface with organic groups that serve as nucleation sites. This preliminary preparation promotes uniform crystal growth and reduces defects while shortening the overall production time, thus resolving the contradiction between reliability and productivity.
4Speed
If ultrasonic chemistry method is used, then reaction speed is improved, but product purity decreases and production efficiency remains limited
Solution Approach 1:
The patent replaces the mechanical ultrasonic treatment with a chemically-driven approach using surface-modified substrates and controlled coordination reactions. This substitution achieves fast reaction speeds through chemical mechanisms while maintaining high product purity, resolving the contradiction between speed and manufacturing precision.
