Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fluid sensor device uses holographic imaging methods to characterize particle identity and concentration, then particle analysis capability is improved, but optical reflections and scattering occur that degrade image quality
Solution Approach 1:
The patent extracts and removes the harmful optical reflections and scattering from the imaging path by using a specialized fluid flow component design that directs fluid flow away from optical surfaces, eliminating the source of optical interference while maintaining holographic imaging capability
Solution Approach 2:
The patent introduces an intermediary fluid flow component that acts as a mediator between the particle collection media and the imaging system, controlling fluid flow to prevent direct contact between fluid and optical surfaces, thereby eliminating optical reflections and scattering
2Measurement precision
If a fluid sensor device uses a fixed collection media assembly, then alignment stability is improved, but adaptability for different sampling scenarios is reduced
Solution Approach 1:
The patent segments the collection media assembly into a replaceable component that can be independently exchanged, allowing different collection media to be used for different sampling scenarios while maintaining precise alignment through standardized docking features
Solution Approach 2:
The patent introduces dynamic replaceability of the collection media assembly, allowing the system to adapt to different sampling requirements by exchanging media types while maintaining stable alignment through the docking mechanism
3Ease of operation
If a fluid sensor device allows easy access to internal components for cleaning and replacement, then ease of operation is improved, but risk of contamination during maintenance is increased
Solution Approach 1:
The patent employs disposable collection media assemblies that are replaced rather than cleaned, eliminating contamination risk associated with cleaning operations while maintaining ease of operation through simple replaceable design
Solution Approach 2:
The patent extracts the contamination risk by removing the need for cleaning operations entirely, using replaceable components that are disposed of after use, thereby eliminating the harmful factor of contamination during maintenance
