Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used for producing organic compounds containing heteroatoms under light irradiation, then the production process can proceed, but the reaction efficiency and product yield are insufficient
Solution Approach 1:
The patent changes the physical state parameter of vinylidene fluoride from gas to ultrafine bubbles dispersed in liquid medium. This parameter change increases the interfacial area between reactants, enhances light absorption efficiency, and improves both reaction efficiency and product yield while maintaining the chemical reaction process
Solution Approach 2:
The patent introduces a liquid medium as an intermediary to disperse vinylidene fluoride in the form of ultrafine bubbles. This intermediary facilitates better contact between the gaseous vinylidene fluoride and the liquid-phase reactants, enabling efficient mass transfer and improving reaction performance
