Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fluid delivery systems are used, then standardization is maintained, but extreme flow rates and high temperatures cannot be handled
Solution Approach 1:
The system is divided into modular components: a flow substrate containing fluid pathways, removable fluid handling components, and standardized interfaces. This segmentation allows each component to be optimized for extreme conditions while maintaining overall system manageability through modular assembly.
Solution Approach 2:
The patent employs parameter changes by offering multiple substrate materials (stainless steel, aluminum, brass, polymers) and conduit size variations to adapt the system to different extreme flow rate and temperature requirements, transforming a single standardized design into a family of condition-specific configurations.
2Reliability
If metallic seals are used, then high purity fluid delivery is achieved, but contamination risk increases in certain applications
Solution Approach 1:
The patent allows selection between metallic seals (for high purity applications) and elastomeric seals (for applications where metal contamination is problematic), changing the material parameter to match the specific contamination requirements of different fluid delivery scenarios.
3Ease of operation
If standardized interfaces are used, then ease of assembly is improved, but adaptability to different flow rates and temperatures is reduced
Solution Approach 1:
The standardized interface design enables universal assembly procedures across different component types, while the modular architecture allows the same interface standard to accommodate various substrate materials, conduit sizes, and component configurations, achieving multi-functionality.
4Ease of manufacture
If gaskets are used for sealing, then ease of manufacture is improved, but sealing reliability at extreme temperatures deteriorates
Solution Approach 1:
The patent enables selection between gasket-based sealing (for ease of manufacture at moderate temperatures) and welding-based sealing (for high-temperature reliability), allowing the sealing method parameter to be changed according to the operating temperature requirements.
