Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components (hydraulic pumps, coolers, filter units) are connected separately to the function block via additional piping, then the system can interact with multiple fluid components, but the installation space increases and thermal inconsistencies occur due to long fluid transport paths
Solution Approach 1:
The patent integrates multiple fluid components including filter units, coolers, and hydraulic pumps directly into the function block housing, eliminating the need for separate connections via additional piping. This merging approach reduces installation space while maintaining the ability to interact with multiple fluid components, and shortens fluid transport paths to prevent thermal inconsistencies
2Adaptability or versatility
If additional components are connected via additional piping, then system versatility is achieved, but thermal inconsistencies occur due to long fluid transport paths
Solution Approach 1:
By integrating coolers and other thermal-sensitive components directly into the function block, the patent minimizes fluid transport path length, thereby reducing thermal losses and inconsistencies while maintaining system versatility
Solution Approach 2:
The patent utilizes the three-dimensional installation space within the function block housing to accommodate multiple components in a compact arrangement, allowing versatile component integration without extending fluid transport paths horizontally, thus preventing thermal inconsistencies
3Area of stationary object
If filter elements are completely accommodated within the function block, then installation space is minimized, but the filter housing must be precisely integrated with the function block
Solution Approach 1:
The patent divides the filter unit into a filter element and a filter housing, where the filter housing is integrated into the function block with precise positioning features. This segmentation allows the filter element to be completely accommodated within the function block footprint while using standardized integration interfaces to manage precision requirements
Solution Approach 2:
The filter housing is designed with multi-functional integration into the function block, serving both as a structural housing for the filter element and as a connection interface for fluid paths. This universal design approach simplifies the integration process while achieving compact space utilization
