Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the battery pack is rotated 180 degrees to treat the lower surfaces of battery cells with plasma, then plasma treatment can be performed on the lower surfaces, but the process becomes complicated and productivity decreases
Solution Approach 1:
Instead of rotating the battery pack to access lower surfaces, the invention inverts the approach by placing the plasma treatment unit above the battery cells and using a robot arm to tilt the cells, allowing plasma treatment of lower surfaces without rotation of the entire battery pack
Solution Approach 2:
The invention introduces dynamic tilting of battery cells via robot arm control during plasma treatment, allowing the lower surfaces to be selectively exposed to plasma without fixed positioning or rotation steps, thereby simplifying the process and improving productivity
2Ease of operation
If the distance between battery cells and plasma device varies during rotation, then plasma treatment can be performed, but treatment uniformity decreases
Solution Approach 1:
The robot arm dynamically adjusts the tilt angle of battery cells during plasma treatment to maintain a substantially uniform distance between the lower surfaces of the cells and the plasma device, ensuring consistent treatment quality while allowing operational flexibility
Solution Approach 2:
The system uses feedback control through the robot arm to monitor and adjust the position of battery cells during plasma treatment, maintaining optimal distance uniformity between the cells and plasma device throughout the treatment process
3Manufacturing precision
If multiple process steps (mounting, rotation, removal, treatment, reassembly) are used for plasma treatment, then complete treatment is achieved, but device complexity increases
Solution Approach 1:
The invention merges the plasma treatment step with the existing battery cell mounting process by integrating the plasma treatment unit into the assembly line and using the robot arm to perform both mounting and plasma treatment operations in sequence without requiring separate rotation and reassembly steps
Solution Approach 2:
The invention extracts the plasma treatment function from a separate post-assembly process and integrates it into the mounting process itself, eliminating the need for rotation, removal, and reassembly steps while maintaining treatment completeness
