Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single electrode electrochemical machining is used, then the machine tool structure is simple, but the machining efficiency is low and manufacturing cycle is long
Solution Approach 1:
The patent divides the single electrode into multiple cathode rods arranged in an array, with each rod capable of independent electrochemical machining. This segmentation allows simultaneous machining of multiple cascade channels, dramatically improving productivity while maintaining relatively simple individual rod structures that can be managed through systematic arrangement and control.
2Loss of time
If single electrode machining is used, then the device structure is simple, but the manufacturing cycle is extended
Solution Approach 1:
The patent merges multiple cathode rods into a single integrated electrode array system that operates simultaneously. By combining the functionality of multiple electrodes into one coordinated unit, the system achieves parallel machining of multiple cascade channels, significantly reducing the manufacturing cycle time while the modular array design keeps the overall structure manageable and not excessively complex.
3Productivity
If multi-electrode electrochemical machining is implemented, then machining efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent designs the electrode array with multiple cathode rods that can simultaneously perform different machining functions on different cascade channels. Each rod serves as a universal electrochemical tool that can be positioned and controlled to machine various channels in parallel, achieving high productivity through multi-functionality while the standardized rod design prevents excessive complexity.
