Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individually adapted control blocks are manufactured for each specific hydraulic cylinder, then the control precision and performance are improved, but the manufacturing cost and device complexity increase significantly
Solution Approach 1:
The control block is designed with a generic circuit structure that can serve multiple specific hydraulic cylinders with different numbers of piston areas. By incorporating switchable hydraulic components and means, a single control block design can be configured to control cylinders with 2, 3, or 4 piston areas, eliminating the need to manufacture separate control blocks for each cylinder type while maintaining precise control performance.
Solution Approach 2:
The control block incorporates switchable hydraulic components and means that allow the circuit structure to be dynamically reconfigured. This enables the same physical control block to adapt its hydraulic circuit configuration depending on which specific hydraulic cylinder is being controlled, providing both precision and versatility without increasing manufacturing complexity.
2Reliability
If individually adapted control blocks are manufactured for each specific hydraulic cylinder, then the control performance is improved, but the production cost increases
Solution Approach 1:
A single generic control block design with switchable components can control multiple types of hydraulic cylinders (with 2, 3, or 4 piston areas), eliminating the need to manufacture separate control blocks for each cylinder type. This universality significantly reduces production costs while maintaining the reliability and performance required for each specific application.
3Device complexity
If a generic control block design is used for multiple hydraulic cylinders, then the production cost and device complexity are reduced, but the adaptability to specific cylinder requirements decreases
Solution Approach 1:
The generic control block incorporates switchable hydraulic components and means that enable dynamic reconfiguration of the circuit structure. This allows the control block to adapt its configuration to match the specific requirements of different hydraulic cylinders (with 2, 3, or 4 piston areas), maintaining high adaptability while avoiding the complexity of manufacturing entirely different control block designs for each application.
