Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a power connection busbar spanning the entire battery pack is used, then power connection is achieved, but space utilization is poor and passenger comfort is reduced
Solution Approach 1:
The power connection system is divided into multiple segments: distribution box at the head, power connectors at intermediate positions, and drive connectors at the rear. This segmentation eliminates the need for a single long busbar spanning the entire battery pack, improving space utilization and allowing better arrangement of battery cores in the cavity.
Solution Approach 2:
The power connection components are arranged in a three-dimensional configuration within the battery pack cavity rather than a linear span. The distribution box, power connectors, and drive connectors are positioned at different locations and heights, utilizing vertical and lateral spaces to reduce the overall footprint and improve passenger comfort.
2Power
If a power connection busbar spanning the entire battery pack is used, then power connection is achieved, but the battery pack size increases affecting vehicle design
Solution Approach 1:
The power connection function is segmented into multiple connection points distributed throughout the battery pack. Instead of one long continuous busbar, multiple shorter connection segments are used, reducing the maximum length required and allowing more compact battery pack design.
Solution Approach 2:
The power connectors and distribution box are nested within the battery pack cavity structure, utilizing the existing spatial framework. This nesting approach minimizes the external dimensions of the battery pack while maintaining all necessary power connection functions.
