Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional ionic liquids are used for carbon dioxide capture, then carbon dioxide absorption capacity is achieved, but viscosity is high which hinders application
Solution Approach 1:
The patent changes the chemical parameters of ionic liquids by introducing amino and hydroxyl functional groups, which modifies the molecular structure to reduce intermolecular forces and lower viscosity while maintaining or enhancing carbon dioxide absorption capacity through chemical interaction mechanisms
Solution Approach 2:
The patent creates composite ionic liquid structures combining multiple functional groups (amino, hydroxyl, and ionic liquid components) into a single multifunctional molecule, achieving both low viscosity and high carbon dioxide absorption capacity through synergistic effects of different functional groups
2Object-affected harmful factors
If existing flame retardants are applied to textiles, then flame resistance is achieved, but durability is poor or additional functional properties are lacking
Solution Approach 1:
The patent designs ionic liquids with multiple functional groups that simultaneously provide flame retardancy, antistatic, and antimicrobial properties, allowing a single coating to deliver multiple protective functions and improve durability through enhanced textile interaction
Solution Approach 2:
The patent introduces specific functional groups at different locations within the ionic liquid molecule, where amino groups interact with textile fibers for durability, hydroxyl groups provide flame resistance, and the overall structure delivers antistatic and antimicrobial effects
