Engineering Contradiction Analysis
1Productivity
If traditional battery assembly methods are used with multiple battery cells requiring precise positioning, then the battery structure is stable, but the assembly complexity increases and assembly efficiency decreases
Solution Approach 1:
The battery assembly is segmented into modular units with standardized holders that can be independently assembled. Each holder is designed as a separate component with position-limit portions that can be buckled together, allowing modular assembly without requiring precise positioning of all cells simultaneously. This segmentation reduces assembly complexity while maintaining structural stability.
Solution Approach 2:
The holder design incorporates buckling mechanisms that allow for dynamic adjustment during assembly. The first and second holders can be buckled along the first direction to form position-limit spaces, providing flexibility in the assembly process while ensuring stable positioning of battery cells. This dynamic mechanism simplifies assembly operations.
2Ease of repair
If battery cells are firmly fixed in the battery structure, then the battery stability is improved, but the repair and replacement time increases
Solution Approach 1:
The battery structure is divided into independent modular units with individual holders for each battery cell. Each holder can be independently disassembled by unbuckling the first and second holders, allowing specific cells to be replaced without affecting other cells. This segmentation enables quick repair while maintaining overall structural stability through the modular design.
Solution Approach 2:
The buckling mechanism provides a dynamic connection that can be easily engaged and disengaged. The holders can be firmly fixed during normal operation but can be quickly released when repair is needed. This dynamic fastening mechanism allows the battery to transition between stable operation mode and easy maintenance mode.
3Extent of automation
If high assembly accuracy is required for battery cell positioning, then the battery structure precision is improved, but the automation of assembly becomes difficult
Solution Approach 1:
The positioning function is segmented into the holder structure itself, which contains integrated position-limit portions. These portions provide mechanical guidance and constraint for battery cell placement without requiring high precision alignment. The standardized holder design allows simple positioning that can be easily automated.
Solution Approach 2:
The holder structure provides self-positioning through its buckling mechanism and position-limit portions. When holders are buckled together, they automatically form position-limit spaces that guide battery cell placement. This self-positioning capability reduces the need for high precision manual alignment and facilitates automated assembly.

AI summary
A battery may comprise: a first battery cell; a first holder and a second holder provided at both ends of the first battery cell along a first direction, the first holder may be recessed in a direction away from the second holder along the first direction to form a first position-limit portion, and the second holder may be recessed away from the first holder along the first direction to form a second position-limit portion, so that the first position-limit portion and the second position-limit portion may be oppositely provided, and the first holder and the second holder may be buckled along the first direction, so that the first position-limit portion and the second position-limit portion may cooperate to form a position-limit space for accommodating the first battery cell.
