Battery Temperature Sampling Assembly With Downward Water-Blocking Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High air humidity can lead to condensed water forming on battery cells, which poses a risk of damage to temperature sampling assemblies due to reverse flow into the assembly's opening, compromising the reliability and service life of the battery.
Innovation Solution
The temperature sampling assembly is mounted with a downwardly inclined opening to prevent condensed water from flowing back into the assembly, utilizing a combination of a mounting frame and an elastic thermally-conductive gasket to secure the shell in an inclined position, thereby preventing water ingress and enhancing assembly efficiency and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening of the temperature sampling assembly is arranged horizontally or upwardly, then it is easy to manufacture and install, but condensed water can flow back into the assembly causing damage
Solution Approach 1:
The opening of the temperature sampling assembly is designed to be inclined downwardly rather than horizontal or upward, creating an asymmetric configuration that uses gravity to prevent condensed water from flowing back into the assembly. This simple geometric change effectively protects the internal components while maintaining manufacturing simplicity
Solution Approach 2:
Instead of trying to prevent water ingress through complex sealing mechanisms or positioning the opening upward, the invention inverts the approach by inclining the opening downwardly, allowing gravity to work in favor of protection rather than against it
2Reliability
If the opening is downwardly inclined to prevent water ingress, then reliability improves, but manufacturing and installation complexity increases
Solution Approach 1:
The opening is designed with a simple downward inclination angle, creating an asymmetric structure that is straightforward to manufacture. The mounting frame includes corresponding asymmetric features that guide proper installation, making the process intuitive despite the non-horizontal orientation
3Reliability
If complex sealing structures are used to prevent condensed water entry, then protection effectiveness improves, but device complexity and cost increase
Solution Approach 1:
The invention converts the harmful effect of gravity (which causes condensed water to flow downward) into a beneficial protective mechanism. By inclining the opening downwardly, gravity naturally prevents water from entering the assembly, eliminating the need for complex sealing structures or protective mechanisms
Solution Approach 2:
The invention extracts and eliminates the complex sealing structures from the design, relying instead on the simple geometric inclination of the opening to provide protection. This simplifies the overall device structure while maintaining effective protection against condensed water

Function Achieved in This Case
This configuration reduces the risk of damage to the temperature sampling assembly, improves its stability and service life, and enhances the overall reliability of the battery by preventing condensed water from entering the assembly, thus ensuring better performance and safety.
Implementation Method 1
an elastic thermally-conductive gasket is located between the shell and the battery cell; and under a combined limiting action of the mounting frame and the elastic thermally-conductive gasket, the shell is fixed on the battery cell
Implementation Method 2
the opening is provided in a downwardly inclined direction... the downwardly inclined opening of the temperature sampling assembly can prevent the condensed water from reversely flowing into the interior of the shell
