Solution Overview
Problem
Traditional plasma-electrolytic polishing methods require soaking the workpiece in an electrolytic cell, limiting their application range due to spatial constraints and potential pollution issues.
Innovation Solution
A local polishing apparatus and system that uses a jet module with an electrolyte and gas communication port, connected to a motion mechanism, allowing for precise plasma-electrolytic polishing on specific areas of an object without complete immersion, using an electrolyte jet mode that combines with a gas jet to form an annular gas wall, enhancing accuracy and preventing excessive polishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plasma-electrolytic polishing soaks the workpiece in an electrolytic cell, then the polishing process can be performed, but the application range is limited due to spatial constraints and the workpiece cannot be processed in complex positions
Solution Approach 1:
The patent divides the polishing system into a stationary electrolytic cell and a movable jet module. The jet module can be positioned at different locations around the workpiece, allowing polishing of complex shapes and hard-to-reach areas without requiring the entire workpiece to be immersed in the electrolytic cell.
Solution Approach 2:
The patent introduces a jet module as an intermediary device that delivers electrolyte and plasma to the workpiece surface through controlled jets. This mediator enables localized polishing without direct contact or immersion, expanding the applicability to complex geometries while maintaining process effectiveness.
2Manufacturing precision
If traditional plasma-electrolytic polishing uses complete immersion, then the entire workpiece surface can be polished, but the polishing accuracy is reduced and excessive material removal may occur
Solution Approach 1:
The patent applies local quality by concentrating the electrolyte and plasma delivery to specific target areas through the jet module. This localized approach allows precise control over which areas are polished and to what extent, improving accuracy and preventing unnecessary material removal from non-critical areas.
Solution Approach 2:
The patent uses partial action by applying the plasma-electrolytic polishing process only to the specific areas requiring refinement, rather than treating the entire workpiece surface. This selective approach minimizes material removal while achieving the desired surface quality in critical zones.
3Object-affected harmful factors
If traditional plasma-electrolytic polishing is performed in a soaking manner, then the process is simple to operate, but pollution is generated and the process is not environmentally friendly
Solution Approach 1:
The patent extracts the electrolyte processing from a large-volume soaking bath and concentrates it into controlled jets delivered by the movable module. This extraction reduces the amount of electrolyte required, minimizes waste generation, and allows for more efficient resource utilization while maintaining polishing effectiveness.
Solution Approach 2:
The patent employs hydraulic principles by using controlled fluid jets to deliver the electrolyte precisely to the workpiece surface. This approach replaces the traditional soaking method with a targeted fluid delivery system that reduces overall electrolyte consumption and environmental impact while maintaining operational control.
