Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional connection techniques are used to connect valve drive to valve membrane, then assembly is straightforward, but assembly errors occur and play between components increases
Solution Approach 1:
The patent introduces an intermediate body with control sections that acts as a mediator between the valve drive and valve membrane. This intermediate body includes guide sections that precisely guide the pin through the membrane, eliminating assembly errors and component play while maintaining a relatively simple overall device structure.
Solution Approach 2:
The intermediate body is pre-configured with control sections and guide sections before assembly. The guide sections are预先 shaped to ensure precise alignment and guidance of the pin during insertion, preventing assembly errors before they occur rather than correcting them afterward.
2Reliability
If complex fixing solutions are implemented to reduce play between components, then component stability improves, but device complexity and costs increase
Solution Approach 1:
The intermediate body serves as a stabilizing intermediary that incorporates control sections to precisely position and secure the pin connection. This mediator ensures reliable connection stability through its pre-configured control geometry rather than requiring complex additional fixing mechanisms.
Solution Approach 2:
The control sections of the intermediate body are designed to create an equipotential connection state where the pin is precisely guided and positioned, eliminating play and ensuring stable connection without requiring asymmetric or complex fixing structures.
3Productivity
If manual assembly procedures are used for valve membrane connection, then flexibility is maintained, but assembly time and productivity are reduced
Solution Approach 1:
The intermediate body is pre-configured with control sections and guide sections that automatically guide the pin through the membrane during assembly. This preliminary configuration enables rapid, error-proof assembly without requiring complex manual manipulation or specialized tools, thus improving productivity while maintaining operational simplicity.
4Manufacturing precision
If precise alignment mechanisms are added to eliminate play between components, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The intermediate body acts as a precision alignment intermediary, incorporating pre-configured control sections and guide sections that automatically ensure precise alignment of the pin with the membrane opening. This intermediary approach achieves high manufacturing precision without requiring complex external alignment mechanisms or procedures.
