Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic distributor blocks face challenges in optimizing flow guidance due to sharp-edged corners and complex manufacturing processes, leading to increased flow resistance and noise emission, especially when diverting fluid flow by more than 90 degrees.
Innovation Solution
A hydraulic distributor block with continuously curved flow ducts, produced through casting or 3D printing, eliminating the need for auxiliary bores and sharp edges, allowing for efficient fluid guidance and reduced noise emission, while enabling flexible assembly and increased mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting machining process is used to manufacture distributor block, then manufacturing precision can be achieved, but flow resistance increases due to sharp-edged corners in flow ducts
Solution Approach 1:
The patent applies curvature principle by replacing sharp-edged corners with continuously curved flow ducts. The flow ducts are designed with smooth bends and rounded transitions instead of rectilinear paths meeting at right angles. This eliminates sharp edges that cause flow separation and turbulence, thereby reducing flow resistance while maintaining manufacturing precision through controlled curvature radii.
2Area of stationary object
If auxiliary bores are used to achieve flow duct diversion greater than 90 degrees, then installation space requirements are met, but device complexity increases
Solution Approach 1:
The patent merges the flow duct diversion function into the main distributor block structure. Instead of using separate auxiliary bores that need to be closed off later, the flow ducts are integrated directly into the block with continuous curved paths that achieve diversions greater than 90 degrees. This integration eliminates the need for auxiliary components and reduces device complexity while meeting installation space requirements.
3Ease of manufacture
If rectilinear bore holes meeting at right angles are used, then manufacturing by cutting process is simple, but flow guidance is suboptimal due to sharp edges
Solution Approach 1:
The patent replaces rectilinear bore holes with continuously curved flow ducts that have smooth transitions and rounded corners. This eliminates the sharp edges generated by conventional drilling and milling operations that meet at right angles. The curved geometry reduces flow separation, swirling, and noise generation while remaining manufacturable through adapted machining processes or casting methods.
