Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stable gap is maintained by downward feed of the spindle, then processing precision can be achieved, but electrolysis products cannot be removed completely due to insufficient electrolyte renewal
Solution Approach 1:
The patent introduces a high-frequency reciprocating twist and micro-vibrating unit that drives the electrode to perform micro-vibrations and reciprocating twists. This mechanical vibration perturbs the electrolyte in the gap, enhancing convection and enabling complete removal of electrolysis products and bubbles, thereby resolving the contradiction between maintaining stable gap for precision and removing electrolysis products.
Solution Approach 2:
The electrode performs periodic micro-vibrations and reciprocating twists at high frequency during the electrochemical process. This periodic action continuously renews the electrolyte in the gap, preventing accumulation of electrolysis products while maintaining the average gap stability required for processing precision.
2Object-generated harmful factors
If mechanisms such as crank or motor are set on the spindle to vibrate the electrode, then electrolyte renewal is sufficient, but the complexity of the apparatus and processing cost increase
Solution Approach 1:
The patent combines the reciprocating swing unit and the high-frequency reciprocating twist and micro-vibrating unit into a single integrated system mounted on the spindle. This merging of functions reduces the number of separate mechanisms compared to using independent crank or motor systems, thereby reducing apparatus complexity while achieving sufficient electrolyte renewal.
Solution Approach 2:
The reciprocating swing unit serves multiple functions: it provides the high-frequency reciprocating twist and micro-vibrations for electrolyte renewal, and it also simplifies the electrode shape to reduce fabrication time and cost. This multi-functionality reduces the need for additional specialized components, lowering overall apparatus complexity.
3Object-generated harmful factors
If the electrode performs up-and-down vibration to renew electrolyte, then electrolyte renewal is sufficient, but the gap width varies resulting in unstable electrolysis
Solution Approach 1:
The patent uses high-frequency reciprocating twist and micro-vibrations instead of large-amplitude up-and-down vibrations. These subtle mechanical vibrations are sufficient to perturb the electrolyte and remove products without causing significant variations in gap width, thereby maintaining electrolysis stability while achieving adequate electrolyte renewal.
Solution Approach 2:
The patent changes the vibration parameters from large-amplitude up-and-down motion to high-frequency reciprocating twist and micro-vibrations with minimal amplitude. This parameter change allows electrolyte renewal through enhanced convection while keeping the average gap width stable, preventing instability in the electrolysis process.
4Manufacturing precision
If a complex shape electrode is used to match the workpiece shape, then processing precision is achieved, but fabrication time and cost increase
Solution Approach 1:
Instead of creating a complex-shaped electrode to match the desired workpiece shape, the patent inverts the approach by using a simple-shaped electrode combined with reciprocating swing motion. The reciprocating swing unit creates the complex geometry through its运动 path, allowing simple electrodes to produce complex workpiece shapes, thereby reducing fabrication time and cost while maintaining processing precision.
Solution Approach 2:
The patent introduces dynamic motion (reciprocating swing) to the electrode system, allowing a static simple-shaped electrode to create dynamic complex processing paths. This transforms the problem from fabricating complex static electrode shapes to controlling dynamic motion, significantly reducing electrode fabrication complexity and time while achieving the same processing precision.

AI summary
The present invention relates an electrochemical processing apparatus and a processing method thereof. A reciprocating swing unit is used to drive the processing electrode to process a workpiece, and thus simplifying fabrication of the processing electrode, and shortening processes and reducing costs. In addition, by using a high-frequency reciprocating twist and micro-vibrating unit to drive the processing electrode to perform high-frequency reciprocating twists and micro-vibrations, the processing electrode can perform twist without varying the processing gap. Thereby, the electrolyte in the gap can be perturbed and renewed continuously. Accordingly, bubbles and products produced during electrolysis can be removed sufficiently, enhancing processing precision and surface quality using the processing electrode on processing the workpiece.
