Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensing components are used in battery modules, then voltage sensing function is achieved, but assembly complexity increases and manufacturing time is extended
Solution Approach 1:
The patent combines the sensing component with the bus bar into an integrated sensing bus bar assembly. The sensing component is mounted on the bus bar, merging two previously separate components (sensing component and bus bar) into one integrated unit, thereby simplifying assembly procedures and reducing manufacturing time while maintaining the voltage sensing function
Solution Approach 2:
The bus bar is designed to serve multiple functions: it acts as both the electrical connection component and the mounting structure for the sensing component. This multi-functionality reduces the number of separate components needed, simplifying the overall assembly process
2Reliability
If traditional sensing components are used in battery modules, then voltage sensing function is achieved, but manufacturing cost increases
Solution Approach 1:
By integrating the sensing component with the bus bar, the patent reduces the total number of components that need to be manufactured, stored, and assembled. This consolidation leads to lower manufacturing costs through reduced material usage, simplified production processes, and decreased assembly time
3Reliability
If traditional sensing components are used in battery modules, then voltage sensing function is achieved, but automation difficulty increases
Solution Approach 1:
The integrated sensing bus bar assembly with pre-mounted sensing components allows for easier automation as the entire assembly can be installed as a single unit using automated placement equipment, rather than requiring separate assembly steps for the bus bar and sensing components
4Reliability
If sensing components are added to battery modules, then voltage sensing capability is improved, but assembly time is extended
Solution Approach 1:
The sensing component is pre-mounted on the bus bar during bus bar fabrication, rather than being attached during battery module assembly. This preliminary action allows the sensing component to be integrated into the bus bar structure before the bus bar is installed in the battery module, significantly reducing assembly time
Solution Approach 2:
By combining the sensing component and bus bar into one integrated assembly, the patent enables simultaneous installation of both components in a single step, eliminating the need for separate assembly operations and reducing overall assembly time
