Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If distributor pipes, eductors, or Venturi nozzles are used to supply electrolyte flow, then the electrolyte flow can be delivered to the object, but the flow becomes chaotic and uncontrollable causing inhomogeneous layer thickness distribution
Solution Approach 1:
The electrolyte distribution system is segmented into multiple distributor plates arranged in series, with each plate having multiple outlet openings. This segmentation divides the chaotic flow into multiple controlled streams that emerge as parallel laminar flows, eliminating eddying and ensuring homogeneous layer thickness distribution across the object surface.
Solution Approach 2:
Different regions of the object surface are served by multiple distributor plates positioned at different locations. Each distributor plate provides localized controlled flow to its corresponding region, ensuring that each area receives appropriate electrolyte flow rates for homogeneous deposition, rather than relying on a single uncontrolled flow source.
2Manufacturing precision
If a single distributor plate is used, then the device complexity is low, but the electrolyte flow homogeneity is insufficient
Solution Approach 1:
The system uses multiple distributor plates arranged in series, with each plate segmenting the flow further. The first distributor plate creates initial flow distribution, and subsequent plates refine this distribution to achieve high homogeneity. This segmented approach achieves superior coating quality while keeping each individual plate relatively simple in design.
