Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accumulation of liquid within the case of a battery pack can cause short-circuits between the positive and negative electrodes of the battery module, leading to performance issues and reliability concerns.
Innovation Solution
A battery pack design featuring a case with a drain hole and a blocking member to prevent the binder from entering the drain hole, allowing liquid to be discharged while preventing clogging and ensuring normal drainage, thereby reducing the risk of short-circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the binder is used to fix the battery module, then the battery module is securely mounted, but the binder may flow into the drain hole and cause clogging
Solution Approach 1:
The blocking member serves as a mediator that separates the binder application area from the drain hole. It allows the binder to perform its fixation function on the battery module while physically preventing the binder from flowing into and clogging the drain hole.
2Device complexity
If liquid accumulates in the case, then the case structure remains simple, but short-circuit between electrodes may occur
Solution Approach 1:
The drain hole extracts the harmful liquid from the case interior, removing it from the potential short-circuit path between electrodes. This allows the case structure to remain simple while actively preventing the harmful effect of liquid accumulation.
