Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery connecting pieces fail to effectively couple electrode poles when they are arranged opposite to each other, leading to a high risk of short circuits and reduced battery safety.
Innovation Solution
A 'U' shaped connecting piece with two parallel and spaced-apart connecting bodies that couple positive and negative electrodes of adjacent battery modules, ensuring series connection while maintaining separation to prevent short circuits.

Engineering Contradiction Analysis
1Reliability
If traditional connecting pieces are used for electrode poles arranged opposite to each other, then the connecting structure is simple, but the risk of short circuit increases and connection reliability deteriorates
Solution Approach 1:
The connecting piece transitions from a planar structure to a three-dimensional folded structure with multiple layers. The first and second connecting portions are arranged in different spatial planes, allowing the connecting piece to bridge electrode poles positioned opposite to each other while maintaining electrical isolation between positive and negative terminals.
Solution Approach 2:
The connecting piece is divided into multiple functional segments: a first connecting portion for connecting to the first electrode pole, a second connecting portion for connecting to the second electrode pole, and an isolating portion that physically separates these connecting portions. This segmentation prevents direct contact between positive and negative electrodes while maintaining electrical connection.
2Volume of moving object
If battery modules are arranged with electrode poles facing each other to achieve compact layout, then the space utilization improves, but the risk of short circuit between positive and negative electrodes increases
Solution Approach 1:
The isolating portion acts as an intermediary element between the first and second connecting portions. It physically separates the positive and negative electrode connections while allowing the connecting piece to maintain structural integrity and provide mechanical support for the electrical connection.
Solution Approach 2:
By utilizing three-dimensional spatial arrangement with the isolating portion extending between connecting portions in a direction perpendicular to the electrode connection planes, the design achieves both compact volume and effective electrical isolation.
