Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If total voltage is supplied to electrode assembly without division, then simple voltage application is achieved, but short-circuits occur and material removal efficiency decreases
Solution Approach 1:
The electrode assembly is divided into multiple independently controllable electrode tubes, each receiving a portion of the total voltage through the dividing circuit. This segmentation allows precise control over voltage distribution to individual electrodes, preventing short-circuits while maintaining system functionality.
Solution Approach 2:
The detecting circuit continuously monitors the voltage applied to each electrode tube and feeds back this information to the controller. When a short-circuit or abnormal condition is detected, the controller adjusts the voltage distribution in real-time, ensuring reliable operation and preventing damage to the electrode assembly.
2Productivity
If voltage is not precisely controlled per electrode tube, then simpler power supply is used, but material removal efficiency and machining accuracy deteriorate
Solution Approach 1:
The power supply system is segmented into multiple independent voltage channels, each dedicated to controlling a specific electrode tube. The dividing circuit allocates appropriate voltage to each electrode based on machining requirements, enabling optimized material removal efficiency for different regions of the workpiece simultaneously.
Solution Approach 2:
Each electrode tube receives a customized voltage level tailored to its specific machining task and position in the electrode assembly. This local quality control ensures that each electrode operates at optimal voltage for its function, maximizing overall material removal efficiency and machining accuracy.
3Manufacturing precision
If electrode assembly moves closer to workpiece for better machining, then material removal precision improves, but short-circuit risk increases
Solution Approach 1:
The detecting circuit continuously monitors voltage conditions as the electrode assembly approaches the workpiece. When the gap becomes too small or short-circuit conditions are detected, the feedback signal triggers the controller to adjust voltage distribution or retract affected electrodes, maintaining machining precision while preventing short-circuits.
Solution Approach 2:
The voltage distribution to each electrode tube is dynamically adjusted based on real-time detection feedback. As electrodes approach the workpiece, the system adaptively modifies voltage levels to maintain optimal machining conditions while preventing harmful short-circuit effects.

AI summary
An electrolytic machining system includes a controller, a drive member coupled to the controller, a power supply, a diving circuit, a detecting circuit, and an electrode module. The diving circuit is coupled to the power supply module and configured to divide a total voltage taken from the power supply module into a plurality of independent working voltages. The detecting circuit is coupled to the dividing circuit and the electrode assembly. The detecting circuit detects each independent working voltage and feeds back information as to the level of the independent working voltage to the controller as the electrode assembly is moved towards a workpiece. When the detection indicates an incorrect working voltage, the controller controls the drive member to move the electrode assembly away from the workpiece.
