Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing flow adjustment devices are used, then flow rate control is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent integrates the flow adjustment device directly into the manifold structure, merging previously separate components (manifold and flow adjustment device) into a single integrated unit. This eliminates the need for additional connecting elements and reduces overall system complexity while maintaining flow control functionality.
Solution Approach 2:
The manifold is designed to serve multiple functions: it acts as both a distribution manifold and houses the flow adjustment devices within its structure. This multi-functionality eliminates the need for separate flow control components, reducing device complexity while maintaining reliable flow rate control.
2Reliability
If existing flow adjustment devices are used, then flow rate control is achieved, but installation and retrofitting become difficult
Solution Approach 1:
By integrating the flow adjustment device into the manifold structure, the patent enables easier installation and retrofitting. The integrated design eliminates the need for complex assembly of separate components and additional fluid-tight couplings, allowing for simpler installation procedures in existing hydraulic plants.
Solution Approach 2:
The flow adjustment device is designed as a modular component that can be integrated into the manifold structure. This segmentation allows for easier installation and maintenance, as the flow control function is provided as a discrete, replaceable unit within the manifold rather than requiring complex integration of multiple separate components.
3Reliability
If existing flow adjustment devices are used, then flow regulation is achieved, but manufacturing costs increase
Solution Approach 1:
The integration of the flow adjustment device into the manifold structure reduces the total number of components that need to be manufactured and assembled. This merging of functions reduces manufacturing costs by eliminating the need for separate connecting elements, additional sealing components, and complex assembly procedures.
Solution Approach 2:
The manifold is designed to perform multiple functions including fluid distribution and flow control. This multi-functionality reduces the total component count and simplifies manufacturing processes, thereby reducing overall manufacturing costs while maintaining reliable flow regulation capability.
