Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional silane compounds are used for surface treatment, then the treatment process is simple, but water- and oil-repellency is insufficient
Solution Approach 1:
The patent employs composite materials by combining fluorine-containing organic groups (providing hydrophobicity) with silane compounds (providing surface treatment capability). This composite structure achieves both water- and oil-repellency while maintaining ease of application through standard surface treatment processes.
Solution Approach 2:
The patent modifies the chemical parameters of the silane compound by introducing fluorine atoms at specific positions (A1, A2) with defined valencies (γ11, γ12). This parameter change enhances the repellency properties while maintaining the fundamental silane structure and application method.
2Reliability
If fluorine atoms are introduced to enhance repellency, then water- and oil-repellency improves, but manufacturing complexity increases
Solution Approach 1:
The patent segments the fluorine-containing organic group into distinct components (A1 fluorine atoms, A2 halogen atoms, γ11 and γ12 valency parameters). This segmentation allows for systematic variation of fluorine content and positioning, enabling optimization of durability and resistance while managing synthesis complexity through controlled modification.
