Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional methods (silane-modified polyethylene or acrylic polymer emulsion) are used to improve adhesion to inorganic substrates, then adhesion is enhanced, but the composition becomes complex and requires multiple components
Solution Approach 1:
The patent extracts and eliminates the need for complex adhesion promoters (silane-modified polyethylene or acrylic polymer emulsion) by using a simplified composition consisting of polyvinylidene fluoride and polyacrylonitrile in specific ratios (95:5 to 50:50 by weight), thereby reducing composition complexity while maintaining adhesion performance
Solution Approach 2:
The patent changes the compositional parameters by specifying precise weight ratio ranges of polyvinylidene fluoride (95:5 to 50:50) and polyacrylonitrile, which optimizes adhesion to inorganic substrates without requiring additional adhesion promoters, thus simplifying the overall composition
2Reliability
If polyvinylidene fluoride is used as the main component for chemical resistance, then chemical resistance is improved, but adhesion to inorganic substrates deteriorates
Solution Approach 1:
The patent applies local quality by using polyvinylidene fluoride as the main component (providing chemical resistance) while locally incorporating polyacrylonitrile in specific ratios (5:95 to 50:50 by weight) to provide adhesion to inorganic substrates, thereby achieving both chemical resistance and adhesion through compositional optimization
3Strength
If acrylic polymer emulsion or silane-modified polyethylene is used to improve adhesion, then adhesion is enhanced, but manufacturing cost increases due to multiple components
Solution Approach 1:
The patent extracts and eliminates the need for expensive adhesion promoters (acrylic polymer emulsion or silane-modified polyethylene) by using a cost-effective composition of polyvinylidene fluoride and polyacrylonitrile in specific ratios, thereby reducing manufacturing cost while maintaining adhesion performance
Solution Approach 2:
The patent employs cheaper polymer materials (polyvinylidene fluoride and polyacrylonitrile) in optimized ratios to replace expensive adhesion promoters, achieving adhesion functionality at lower cost without requiring additional components
