Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pilot valve is standardized in common or in a plurality of limited kinds different in capacity, then mass production may be enabled and cost may be reduced, but the electrification system must be connected to each pilot valve and the pilot valve must be fixed to the main directional control valve by a simple and inexpensive means
Solution Approach 1:
The patent merges the electrification system (terminal block with electrical connections) and the mechanical fixing system (fixing plate with mounting holes) into a single integrated solenoid-valve holder component. This combination allows the pilot valve to be simultaneously electrically connected and mechanically fixed to the main directional control valve through a single assembly operation, reducing overall system complexity while maintaining mass production benefits
Solution Approach 2:
The solenoid-valve holder is designed as a universal mounting structure that can accommodate different capacities and specifications of pilot valves while providing standardized electrical connections and mechanical fixing. The fixing plate with standardized holes and the terminal block with multiple terminals create a multi-functional interface that works across various valve types, enabling both cost reduction through standardization and ease of connection
2Adaptability or versatility
If each pilot valve is simply connected to the main directional control valves with various specifications, then cost reduction is achieved, but the connection means must be simple and inexpensive
Solution Approach 1:
The fixing plate is designed with a universal mounting structure featuring standardized holes and interfaces that can accommodate pilot valves of different capacities and specifications. The terminal block provides a standardized electrical connection interface that works across various valve types, enabling simple and inexpensive connections while maintaining broad compatibility with different main directional control valves
3Adaptability or versatility
If the solenoid valve is mounted on a pneumatic instrument, then operational versatility is achieved, but the mounting structure must be simple and cost-effective
Solution Approach 1:
The mounting structure is segmented into distinct functional components: the fixing plate for mechanical attachment to the pneumatic instrument, the terminal block for electrical connections, and the side covers for protection. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity and cost-effectiveness of the complete mounting structure
