Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery manufacturing, pressing batteries in one direction to achieve a specified size often results in undesired deformation and uneven surfaces in other directions, making it difficult to achieve desired flatness.
Innovation Solution
A battery pressing device with multiple pressing mechanisms operating in perpendicular directions to apply pressure simultaneously in multiple dimensions, including a first pressing mechanism for the primary direction and secondary mechanisms for perpendicular directions, along with an optional third mechanism for electrode terminal alignment, to reduce deformation and enhance flatness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the battery is pressed in one direction to achieve a specified size, then the size requirement is met, but the surface of the battery in other directions becomes deformed and uneven
Solution Approach 1:
The patent applies multi-directional pressing mechanisms that extend the pressing action from a single dimension to multiple dimensions. By arranging pressing mechanisms in different directions (first pressing mechanism in the first direction, second pressing mechanism in the second direction perpendicular to the first direction), the system simultaneously controls both the size and surface flatness of the battery, resolving the contradiction between size precision and surface flatness.
2Device complexity
If a single pressing mechanism is used to press the battery, then the device structure is simple, but the battery surface becomes deformed in directions other than the pressing direction
Solution Approach 1:
The patent introduces pressing mechanisms in multiple spatial dimensions to address surface flatness issues. The first pressing mechanism presses in the first direction while the second pressing mechanism presses in the second direction perpendicular to the first direction, creating a multi-dimensional pressing system that maintains battery surface flatness without excessive structural complexity.
3Shape
If multiple pressing mechanisms are added to press in perpendicular directions, then the battery surface flatness is improved, but the device complexity increases
Solution Approach 1:
The patent segments the pressing function into multiple independent pressing mechanisms, each responsible for a specific direction. The first pressing mechanism handles pressing in the first direction while the second pressing mechanism handles pressing in the second direction. This segmentation allows for modular design and independent optimization of each pressing mechanism, managing overall device complexity through functional decomposition.
Solution Approach 2:
The pressing device is designed with multi-functional capabilities where the same basic pressing mechanism structure can be applied in different directions. The first pressing mechanism and second pressing mechanism share similar functional characteristics but operate in perpendicular directions, allowing for standardized components and reduced overall complexity despite the multi-directional functionality.

AI summary
Embodiments of the present application provide a battery pressing device, including: a first pressing mechanism for pressing a battery in a first direction; and a second pressing mechanism for pressing the battery in a second direction perpendicular to the first direction. With the battery pressing device of the present application, the battery can be pressed in the first direction by using the first pressing mechanism while pressing the battery in the second direction by using the second pressing mechanism, thereby reducing or suppressing the undesired deformation of the battery in the second direction and improving the flatness of the battery in the second direction.
