Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing jigs are used to fasten electrode leads, then the battery cell can be secured for charging and discharging, but the contact resistance varies due to deviations in fastening method and insertion depth
Solution Approach 1:
The guide structure is pre-positioned at a predetermined distance from the pressurizing jig to guide the electrode lead into the correct position before pressurization occurs. This preliminary guiding action ensures that the electrode lead is properly aligned and inserted to the correct depth before the fastening force is applied, eliminating deviations in fastening method and ensuring consistent contact resistance across all battery cells.
Solution Approach 2:
The guide acts as an intermediary element between the pressurizing jig and the electrode lead. It mediates the fastening process by providing a predetermined spatial relationship that ensures proper alignment and insertion depth. The guide structure transfers the positioning function from the operator to a fixed mechanical constraint, thereby ensuring manufacturing precision and contact resistance consistency.
2Productivity
If the electrode lead is fastened with excessive or insufficient insertion, then the battery cell can be quickly secured, but the contact resistance becomes unstable and experimental results vary
