Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If welding is used to connect the voltage detection line to the bus bar for automation, then productivity is improved, but positioning accuracy deteriorates due to insufficient positioning structures
Solution Approach 1:
The patent applies preliminary action by pre-positioning the voltage detection line on the support plate before the welding process. The support plate includes a position restricting structure with a receiving surface part and biasing part that preliminarily position the tab terminal of the voltage detection line relative to the bus bar, ensuring accurate positioning is established before automation begins
Solution Approach 2:
The support plate serves as an intermediary component between the voltage detection line and the bus bar. It includes a position restricting structure that mediates the positioning relationship, with a receiving surface part against which the tab terminal abuts and a biasing part that pushes the tab terminal toward the receiving surface part, thereby enabling both automation and precision
2Manufacturing precision
If manual adjustment is performed to achieve positioning accuracy, then manufacturing precision is improved, but productivity deteriorates due to increased labor time
Solution Approach 1:
The support plate enables self-service positioning through its position restricting structure. The biasing part automatically pushes the tab terminal of the voltage detection line toward the receiving surface part, creating self-positioning without requiring manual adjustment by operators, thereby maintaining both precision and productivity
