Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each battery row is equipped with a separate information collection member, then the monitoring precision and reliability of battery cells is improved, but the manufacturing cost and device complexity increase significantly
Solution Approach 1:
The patent merges the information collection functions for multiple battery rows into a single integrated information collection member. This single member includes multiple sampling lines that can respectively connect to battery cells in different rows, allowing one information collection member to perform the function of what would traditionally require multiple separate members, thereby reducing device complexity and manufacturing cost while maintaining monitoring reliability
Solution Approach 2:
The information collection member is designed with multi-functionality to serve multiple battery rows simultaneously. It includes a first sampling line for connecting to first battery cells in a first row and a second sampling line for connecting to second battery cells in a second row, enabling a single component to perform universal monitoring across different battery rows without requiring separate dedicated members for each row
2Measurement precision
If multiple information collection members are used to monitor all battery cells, then the measurement precision of battery cell data is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines multiple sampling functions into a single information collection member that includes multiple sampling lines. This single member can simultaneously sample data from battery cells in different rows through its multiple sampling lines, achieving the same measurement precision that would require multiple separate members while significantly reducing the number of components to be manufactured and assembled
Solution Approach 2:
The patent transitions from a one-to-one correspondence between information collection members and battery rows to a many-to-one relationship by designing the information collection member with multiple sampling lines extending in different directions. This dimensional expansion allows a single member to access multiple battery rows simultaneously, reducing component quantity while maintaining comprehensive monitoring coverage
