Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hose configuration is used for component extraction, then the device complexity is reduced, but the separation precision deteriorates because components mix during extraction
Solution Approach 1:
The extraction system is segmented into multiple independent channels (first extraction channel and second extraction channel) that can selectively extract different components (first component and second component) separately, preventing mixing while maintaining manageable device complexity
Solution Approach 2:
A guide structure is introduced as an intermediary element that guides the extraction needle along a predetermined path, ensuring the needle passes through specific regions to extract components without mixing, thereby improving separation precision without significantly increasing device complexity
2Ease of manufacture
If adhesive coupling is used to assemble the centrifugal container, then the manufacturing process is simplified, but the ease of manufacture deteriorates due to assembly difficulty
Solution Approach 1:
The centrifugal container is divided into separable components (container body, cover, extraction needle assembly) that can be independently manufactured and then easily assembled through simple coupling structures, improving both ease of manufacture and reducing assembly complexity
Solution Approach 2:
The coupling mechanism between container components is designed to be dynamic and reversible, allowing for easy assembly and disassembly without requiring permanent adhesive bonds, thereby improving ease of manufacture while maintaining structural integrity
3Device complexity
If rubber material is used for injection and extraction ports, then the device complexity is reduced, but the measurement precision deteriorates because the needle cannot be positioned exactly
Solution Approach 1:
A guide structure is introduced as an intermediary between the extraction needle and the rubber port material. This guide structure provides precise positioning and alignment, ensuring the needle is positioned exactly at the required location while the rubber material maintains its simplicity and flexibility
Solution Approach 2:
The rubber port material is designed with localized features (such as recesses or guiding structures at specific positions) that provide precise needle positioning only where needed, while the rest of the material maintains its simple rubber construction, thereby improving positioning precision without significantly increasing device complexity
