Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hydrophobic materials are used for interferometric system components, then manufacturing ease and material availability are improved, but bubble adhesion increases causing measurement inaccuracies
Solution Approach 1:
The patent applies a hydrophilic coating composition specifically to the internal surfaces of interferometric system components where bubbles cause measurement errors, while other components can retain their original hydrophobic materials. This localized modification resolves the contradiction by improving measurement precision only where needed without compromising manufacturing ease of other components.
Solution Approach 2:
The patent changes the surface energy parameter of the component internal surfaces by applying a hydrophilic coating. This parameter change transforms the surface properties from hydrophobic (high surface energy) to hydrophilic (low surface energy), thereby reducing bubble adhesion and improving measurement accuracy while maintaining manufacturing feasibility.
2Measurement precision
If hydrophilic coating is applied to reduce bubbles, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent employs a disposable hydrophilic coating composition that can be easily applied and removed or re-applied. This approach avoids the need for complex permanent modifications to the device structure, thereby improving measurement precision while minimizing the increase in device complexity through the use of a simple, replaceable coating layer.
Solution Approach 2:
The hydrophilic coating acts as an intermediary layer between the bubble-prone hydrophobic surface and the liquid sample. This intermediate layer mediates the interaction by preventing bubble adhesion to the underlying surface, thereby improving measurement accuracy without requiring fundamental changes to the device structure.
3Ease of operation
If conventional materials are used without coating, then ease of operation is maintained, but bubble formation and adhesion reduce system efficiency
Solution Approach 1:
The hydrophilic coating composition provides self-service functionality by automatically preventing bubble adhesion to the surface through its inherent hydrophilic properties. This eliminates the need for complex bubble removal mechanisms or additional operational steps, thereby maintaining ease of operation while improving system efficiency by eliminating bubble-related interference.
