Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional pneumatic valve devices use multiple fasteners and complex assembly structures, then the structural stability is improved, but the assembly time and device complexity increase
Solution Approach 1:
The patent combines multiple fastening functions into a single central fastener that secures both the shaft and valve discs arrangement simultaneously. This merging of fastening operations reduces assembly time while maintaining structural stability through the integrated fastening design.
Solution Approach 2:
The central fastener serves multiple functions: it secures the shaft to the valve body, holds the valve discs arrangement in place, and provides a mounting point for the lever arm. This multi-functional design reduces the total number of parts and assembly steps while ensuring structural integrity.
2Stability of the object's composition
If traditional pneumatic valve devices use numerous parts and complex assembly processes, then the structural completeness is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The invention merges multiple structural components and fastening elements into a simplified design with fewer parts. The central fastener replaces multiple separate fasteners, and the integrated shaft-body-lever arm construction reduces the total component count while maintaining structural completeness.
Solution Approach 2:
Each component in the simplified design serves multiple functions. The shaft provides rotational movement and structural support, the central fastener provides multiple fastening functions, and the lever arm integrates with the fastener mounting. This multi-functionality reduces part count while ensuring structural completeness.
3Manufacturing precision
If traditional pneumatic valve devices use expensive manufacturing methods, then the manufacturing precision is improved, but the manufacturing cost increases
Solution Approach 1:
The valve is designed with segmented, modular components that can be manufactured using standard, cost-effective processes. The shaft, valve body, and valve discs are separate elements that can be produced independently using conventional manufacturing methods, then assembled with a simple central fastener, reducing overall manufacturing cost while maintaining precision.
Solution Approach 2:
The design uses standard geometric parameters and common fastener sizes that can be manufactured with conventional precision machining. By avoiding specialized or custom manufacturing processes and using standard parameters throughout, the valve achieves required precision at lower manufacturing cost.
