Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the Z-shaped folding process is used to prepare laminated cells, then the electrode plates and separator can be alternately arranged, but the number of folding times increases and processing steps become numerous, resulting in low production efficiency
Solution Approach 1:
The patent divides the electrode plates into multiple groups (first electrode plate group, second electrode plate group, etc.) and processes them separately before final assembly. This segmentation allows parallel processing of different electrode groups, reducing the total number of sequential folding operations and simplifying the overall processing steps while maintaining the alternating arrangement structure.
2Productivity
If the Z-shaped folding process is used to prepare laminated cells, then the electrode plates and separator can be alternately arranged, but the number of folding times increases, resulting in low production efficiency
Solution Approach 1:
The patent performs preliminary assembly of electrode plates into groups and prepares the separator structure in advance before the final folding operation. By pre-organizing the electrode plates into first and second groups with predetermined arrangements, the actual folding process requires fewer operations and less time, significantly improving production efficiency.
3Manufacturing precision
If multiple folding operations are performed to achieve alternating arrangement, then the electrode structure can be formed, but the processing steps increase and efficiency decreases
Solution Approach 1:
The patent segments the electrode assembly into distinct groups (first electrode plate group, second electrode plate group) that are prepared separately with precise arrangements. This segmentation enables each group to be manufactured with high precision independently, then assembled together, maintaining manufacturing precision while reducing the total number of folding operations required.
