Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery cells are stacked into groups with complex design, then the battery module can achieve high capacity, but the number of components increases and processing difficulty increases, reducing reliability
Solution Approach 1:
The patent merges multiple support functions into a single bracket structure. The bracket integrates support for battery cell groups, positioning for battery cells, and structural stabilization into one unified component, eliminating the need for separate support pieces and reducing overall structural complexity while maintaining high capacity through proper cell arrangement
Solution Approach 2:
The bracket is designed as a multi-functional component that simultaneously provides structural support, cell positioning, and group stabilization. This universal component performs multiple functions that would otherwise require separate parts, thereby reducing component count and simplifying the overall module design
2Quantity of substance
If complex group design is used to arrange battery cells, then high capacity is achieved, but processing difficulty increases and reliability decreases
Solution Approach 1:
The patent segments the battery module into standardized groups of battery cells, with each group independently supported and positioned by the bracket structure. This segmentation allows for modular assembly and simplifies manufacturing processes by enabling standardized handling and positioning of cell groups
Solution Approach 2:
The bracket is pre-designed with integrated positioning features and support structures before assembly. The accommodating grooves and support surfaces are prepared in advance, allowing battery cells and groups to be easily positioned and fixed during assembly, thereby simplifying the manufacturing process
3Strength
If more components are used in the module design, then structural support is enhanced, but the number of parts increases and reliability reduces
Solution Approach 1:
Multiple structural support functions are merged into the single bracket component. The bracket provides support for battery cell groups, positioning for individual cells, and stabilization for the entire module, eliminating the need for multiple separate support parts and thereby improving reliability through reduced component count

AI summary
A battery module includes battery cell groups and a bracket. The bracket includes at least one middle bracket (20) and a top bracket (30). The middle bracket (20) is arranged between, any one or a combination of, the top battery cell group and the non-top battery cell group and adjacent two of the battery cell groups of the non-top battery cell group. The top bracket (30) is arranged on a side of the top battery cell group facing away from the non-top battery cell group. Each of a side surface of the middle bracket (20) adjacent to the battery cell groups and a side surface of the top bracket (30) adjacent to the battery cell groups is provided with first accommodating grooves (21) arranged along the first direction (A). Each of the battery cells (10) is fixed in a corresponding one of the first accommodating grooves (21).
