Battery Module Electrode Connection Layout for Visible Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules lack visual inspection capabilities to confirm the connection state between the conductive metal plate and the second electrode, leading to the risk of defective products being released and potential short-circuiting due to electrical connections between the lid and other components.
Innovation Solution
The battery module design includes visible second electrodes and a conductive metal plate with connecting pieces that allow for easy visual inspection of connections, ensuring non-defective products are produced and reducing the risk of short-circuiting by electrically insulating the lid from the conductive metal plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the conductive metal plate is used to press the battery and provide electrical connection, then power extraction efficiency is improved, but the risk of short-circuiting between the lid and other components increases
Solution Approach 1:
The patent introduces an insulating structure as an intermediary between the conductive metal plate and the lid. This insulating layer prevents direct electrical contact between the conductive metal plate (which is electrically connected to the battery) and the lid (which may contact other components), thereby eliminating the short-circuiting risk while preserving the power extraction function of the conductive metal plate
2Device complexity
If the connection state between the conductive metal plate and the second electrode is not visually inspectable, then manufacturing complexity is reduced, but the risk of defective products being released increases
Solution Approach 1:
The patent makes the second electrode visible through the insulating structure, allowing visual inspection of the connection state between the conductive metal plate and the second electrode. This visibility enables quality control personnel to verify proper connections and identify defects during assembly, thereby reducing the risk of defective products being released without significantly increasing manufacturing complexity
