Battery Connector Engagement Structure for Slip-Free Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery manufacturing process is hindered by the relative slide between the first adapter sheet and the second adapter sheet, leading to decreased accuracy and increased defective rates in welding, which ultimately results in a lower battery qualification rate.
Innovation Solution
The battery design incorporates a first connecting assembly with a first connector and a second connector, where the first connector has a first engaging portion and the second connector has a second engaging portion, allowing them to be accurately and rapidly positioned during welding, preventing relative slip and enhancing manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first adapter sheet is connected to the second adapter sheet using conventional connection methods, then the battery assembly is completed, but relative slide occurs between the sheets during welding, decreasing welding accuracy and increasing defective rate
Solution Approach 1:
The patent applies preliminary action by pre-forming engaging portions (convex and concave structures) on the adapter sheets before the welding process. These engaging portions are prepared in advance to prevent relative sliding during welding, thereby ensuring welding accuracy and improving the battery qualification rate without requiring additional corrective measures during production.
Solution Approach 2:
The patent introduces an intermediary mechanism through the engaging portions (convex and concave structures) that act as mediators between the first and second adapter sheets. These engaging portions prevent relative sliding by providing mechanical interlocking, thereby maintaining welding accuracy and reducing defective rates during the welding process.
2Ease of manufacture
If the first adapter sheet and second adapter sheet are connected without engaging portions, then the connection process is simpler, but relative slide occurs during welding leading to increased defective rate
Solution Approach 1:
The engaging portions are pre-formed on the adapter sheets before assembly, allowing the connection process to remain simple while ensuring welding quality. The convex and concave structures are integrated into the adapter sheet design, requiring no additional complex assembly steps while effectively preventing relative sliding during welding.
3Productivity
If conventional connection methods are used between adapter sheets, then the battery can be assembled, but relative slide decreases welding accuracy and increases defective rate
Solution Approach 1:
The positioning accuracy is improved through preliminary action by pre-forming the engaging portions on the adapter sheets. These structures are prepared in advance to ensure accurate positioning during welding, thereby maintaining high production efficiency while eliminating the need for repositioning or corrective measures during the welding process.
Solution Approach 2:
The engaging portions serve as intermediary elements that facilitate accurate positioning between the first and second adapter sheets. The convex and concave structures provide mechanical guidance and constraint, ensuring precise alignment during assembly and welding operations, thereby improving both positioning accuracy and production efficiency.
