Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling plug-in members for battery packs suffer from outflow and splashing of liquid due to insufficient float, caused by vehicle body vibrations and other factors.
Innovation Solution
A liquid cooling plug-in assembly featuring a first fixed plate, a floating plate, at least one first elastic member, and a plurality of plug-in members, where the plug-in members are connected to the floating plate, and the floating plate is in floating connection with the first fixed plate via the first elastic member, enhancing the float and stability of the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid cooling plug-in members are rigidly connected to the battery pack, then the connection stability is improved, but the device cannot adapt to vehicle body vibrations and causes liquid outflow and splashing
Solution Approach 1:
The plug-in member is designed with a floating connection structure that includes a floating portion capable of dynamic movement relative to the battery pack. This dynamic structure allows the plug-in member to adapt to vehicle body vibrations while maintaining reliable liquid cooling connections, preventing liquid outflow and splashing during vehicle operation
Solution Approach 2:
The floating portion is designed with specific dimensional parameters (length, width, thickness) that enable it to move within a controlled range to absorb vibrations. The elastic member's stiffness and the floating portion's geometry are optimized to provide sufficient floatation while maintaining connection stability under vibrational conditions
2Reliability
If the plug-in member is rigidly fixed, then the liquid cooling connection is stable, but the float is insufficient causing liquid outflow during vibrations
Solution Approach 1:
The plug-in member incorporates a floating portion that can dynamically move to maintain proper connection under vibrational conditions, providing sufficient float to prevent liquid outflow while ensuring stable liquid cooling connection during vehicle operation
Solution Approach 2:
The elastic member is pre-installed between the plug-in member and battery pack to provide beforehand cushioning against vibrations. This elastic element absorbs vibrational energy before it can cause liquid outflow, while maintaining the liquid cooling connection stability throughout vehicle operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents the outflow and splashing of liquid, enhances the stability of the connection, and prolongs the service life of the liquid cooling plug-in device by ensuring a large float and secure attachment of the plug-in members.
Implementation Method 1
