Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The size of voltage detection devices in battery modules increases when all voltage detection lines are drawn through the same side region of voltage detection terminals, leading to potential interference and increased device dimensions.
Innovation Solution
The voltage detection lines are routed through regions between and opposite sides of adjacent voltage detection terminals, utilizing a holding body to manage line routing and reduce interference, allowing for a more compact design.

Engineering Contradiction Analysis
1Device complexity
If all voltage detection lines are drawn through the same side region of voltage detection terminals, then the connection is simplified, but the device size increases
Solution Approach 1:
The voltage detection lines are segmented into different routing paths: some lines are drawn through regions between adjacent voltage detection terminals, while others are drawn through opposite side regions. This segmentation allows lines to be distributed across different spatial zones, reducing concentration in one area and thereby decreasing overall device size while maintaining connection simplicity.
Solution Approach 2:
The patent utilizes multiple dimensional routing strategies by drawing lines through both inter-terminal regions (lateral dimension) and opposite side regions (depth/directional dimension). This multi-dimensional approach to line routing distributes the connections in three-dimensional space rather than confining them to a single plane or region, effectively reducing the footprint of the voltage detection device.
2Device complexity
If voltage detection lines are routed through the same region, then the routing is simplified, but interference between lines increases
Solution Approach 1:
The routing is segmented into multiple distinct paths: lines are routed through regions between adjacent terminals and through opposite side regions. This segmentation physically separates the lines into different spatial channels, reducing electromagnetic interference and signal crosstalk while maintaining relatively simple routing procedures at each terminal.
Solution Approach 2:
The holding body structure serves as an intermediary that facilitates the routing of voltage detection lines through different regions. By providing structured pathways and mounting surfaces, the holding body enables lines to be routed through intermediate regions between terminals and opposite sides, reducing direct line-to-line interference while keeping the routing process manageable.
