Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate connections and pipes are used to connect hydraulic lines from the power source to the multi-connection device, then each line can be independently controlled, but the number of leak points increases significantly and installation complexity increases
Solution Approach 1:
The patent integrates multiple distribution valves and their associated piping into a single integrated block structure. This merging of previously separate components (valves, pipes, fittings) into one unified unit dramatically reduces the number of external connections and potential leak points while maintaining all necessary hydraulic control functions.
Solution Approach 2:
The integrated block serves multiple functions simultaneously: it houses multiple distribution valves for different hydraulic lines, provides flow control, and acts as a manifold for fluid distribution. This multi-functionality eliminates the need for separate piping systems for each line, reducing overall system complexity.
2Ease of operation
If multiple separate distribution valves and pipes are used for each hydraulic line, then each line can be independently controlled, but installation time and maintenance complexity increase
Solution Approach 1:
By combining multiple distribution valves and piping into a single integrated block, the patent reduces installation time by minimizing the number of separate components to be assembled. Maintenance time is also reduced as the integrated design simplifies access and identification of specific lines while maintaining independent control capability.
Solution Approach 2:
The integrated block maintains internal segmentation of hydraulic lines, allowing independent control of each line through individually accessible valve mechanisms within the unified structure. This internal segmentation preserves operational independence while achieving external simplification.
3Adaptability or versatility
If numerous fittings and pipe connections are used between the distribution valve and multi-connection device, then each hydraulic line can be connected, but the cost of materials and installation increases
Solution Approach 1:
The integrated block merges multiple piping systems into a single manufactured unit, eliminating the need for numerous separate fittings and connections. This reduces material costs and installation expenses while maintaining the capability to connect multiple hydraulic lines with different configurations.
Solution Approach 2:
The integrated block provides a universal solution that can accommodate multiple hydraulic lines with different flow requirements through its internal valve system, eliminating the need for custom piping solutions for each line and thereby reducing overall installation cost.

Implementation Method 2
hydraulic elements (for example, as already mentioned, compensation valves, one-way valves, proportional valves, control valves, etc.), to ensure the correct control of the hydraulic power as well as the direction and flow of the operating fluid flow-rate
