Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NMP is used in compositions, then functional properties are maintained, but toxicity to health and environment increases
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of NMP through systematic substitution at different positions (N-1, C-2, C-5) with various groups (alkyl, aryl, heteroaryl, etc.). This structural parameter modification maintains the desired functional properties while reducing the toxic effects associated with the original NMP structure.
Solution Approach 2:
The patent creates composite molecular structures by combining the pyrrolidone core with various substituent groups. These composite structures (e.g., 1-alkyl-5-arylpyrrolidin-2-ones, 1-heteroaryl-5-alkylpyrrolidin-2-ones) integrate beneficial properties while eliminating harmful characteristics of parent NMP.
2Object-affected harmful factors
If NMP substitutes are developed, then toxicity is reduced, but structural complexity increases
Solution Approach 1:
The patent segments the molecular structure into distinct functional regions: the pyrrolidone core (maintaining functional properties) and substituent groups at N-1, C-2, and C-5 positions (modifying toxicity). This segmentation allows independent optimization of functionality and safety.
Solution Approach 2:
The patent applies local quality by introducing specific substituent groups at particular positions on the pyrrolidone ring. Each position (N-1, C-2, C-5) can be independently substituted with different groups tailored to achieve desired toxicity reduction while preserving local functional characteristics.
