Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple battery cells are electrically connected to increase power and capacity, then output voltage and current are improved, but device complexity increases
Solution Approach 1:
Multiple battery cells are electrically connected in series or parallel configurations within a single battery module housing, merging their electrical outputs to achieve higher power and capacity while maintaining a unified structural framework
Solution Approach 2:
The battery module design incorporates universal mounting structures and electrical connection terminals that can accommodate different cell configurations (series/parallel arrangements), allowing the same module structure to serve multiple power requirements
2Quantity of substance
If multiple battery cells are arranged to increase capacity, then energy storage is improved, but volume increases
Solution Approach 1:
Battery cells are arranged in a compact nested configuration where cells are positioned closely together with minimal spacing, and terminal plates are integrated into the cell structure rather than added as separate external components
Solution Approach 2:
The terminal plate extends in multiple dimensions with holes at different depths and orientations, allowing electrical connections to be established in three-dimensional space rather than requiring additional horizontal volume

AI summary
A battery module includes a plurality of battery cells arranged in one direction and electrically connected to one another, the plurality of battery cells each having a current collecting terminal on a top surface thereof, and a terminal plate positioned on the current collecting terminal of one of the battery cells. The terminal plate is in a form of a sideways-oriented U-shape, including a first surface that contacts the current collecting terminal, a second surface that is parallel to the first surface and spaced apart from the first surface by a predetermined distance, and a third surface connecting the first surface and the second surface, the first surface including a first hole and the second surface including a second hole, the first hole and the second hole having different shapes.
