Battery Module Output Electrode Base Securing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery module output electrode bases tend to fall off during transport due to inadequate securing mechanisms, necessitating a design that prevents this issue while maintaining assembly ease and energy density.
Innovation Solution
Incorporation of first and second limiting elements on the output electrode base and end plate, respectively, with stop holes and grooves to limit movement in specific directions, ensuring secure attachment during transport and assembly without obstructing battery cell installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the output electrode base is mounted on the end plate using conventional methods, then the assembly process is simple, but the output electrode base is prone to falling off during transport
Solution Approach 1:
The patent divides the securing mechanism into two independent limiting elements: a first limiting element that limits relative movement along a first direction, and a second limiting element that limits relative movement along a second direction. This segmentation allows each element to perform a specific function, improving connection reliability while keeping the overall structure manageable through functional division.
Solution Approach 2:
The patent transitions from conventional single-direction securing to multi-directional constraint by introducing limiting elements that operate in different spatial dimensions. The first limiting element constrains movement in one direction while the second limiting element constrains movement in another direction, creating a comprehensive three-dimensional securing system that prevents the output electrode base from falling off during transport.
2Reliability
If limiting elements are added to prevent falling off, then connection reliability improves, but the assembly process becomes more complex
Solution Approach 1:
The patent combines the functions of multiple securing mechanisms into an integrated assembly process. The first and second limiting elements are incorporated into the end plate and output electrode base structures, allowing both limiting functions to be achieved through a single mounting operation rather than separate assembly steps. This merging of functions maintains assembly ease while improving connection reliability.
Solution Approach 2:
The limiting elements are designed to automatically perform their securing function once the output electrode base is mounted on the end plate. The first limiting element and second limiting element inherently constrain relative movement in their respective directions without requiring additional active control or complex adjustment mechanisms, allowing the structure to self-regulate and simplify the assembly process.
3Reliability
If securing structures are added to the end plate, then the output electrode base is secured during transport, but the installation space for battery cells may be reduced
Solution Approach 1:
The patent applies limiting elements at specific localized positions on the end plate and output electrode base rather than using comprehensive securing structures across the entire surface. The first limiting element and second limiting element are strategically positioned to provide necessary constraints while leaving the majority of the end plate surface available for battery cell installation, thus maintaining adequate installation space while improving connection reliability.

AI summary
A battery module includes an output electrode base and an end plate, and the output electrode base is inserted into and fitted to the end plate. A first limiting element is disposed on the output electrode base, a limiting plate is disposed on the end plate, and the first limiting element is fitted to the limiting plate. A stop hole is provided in one of the output electrode base and the end plate, and a second limiting element is disposed on the other. The second limiting element is accommodated in the stop hole; and the second limiting element is fitted to the stop hole. The first limiting element is fitted to the limiting plate and the second limiting element is fitted to the stop hole to limit the relative movement of the output electrode base and the end plate.
