Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrolyte solution is supplied to the middle position between the pair of electrodes for machining, then the machining process can be performed, but the distribution of the electrolyte solution becomes nonuniform and machining accuracy decreases
Solution Approach 1:
The single electrolyte solution supply at the middle position is segmented into multiple nozzles positioned along the electrode, dividing the supply into multiple localized points to achieve uniform distribution across the machining area
Solution Approach 2:
The electrolyte solution supply is changed from a single centralized point to multiple distributed nozzles, providing locally optimized electrolyte distribution at different positions along the electrode to ensure uniformity across the entire machining area
2Productivity
If a single electrolyte solution supply point is used at the middle position, then the device structure is simple, but the processing time is long and productivity is low
Solution Approach 1:
The single electrolyte supply system is segmented into multiple nozzles positioned along the electrode, enabling parallel electrolyte delivery to multiple locations and significantly reducing processing time despite increased structural complexity
Solution Approach 2:
The electrolyte supply is extended from a single point in one location to multiple points distributed along the length of the electrode, adding a spatial dimension to the supply system to improve processing efficiency
