Temperature Sensor Rail-Mount Structure for Tight Battery Cell Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation structure of temperature sensors requires a large space, limiting the options for mounting positions and reducing the degree of freedom in installation modes, making it difficult to efficiently monitor temperatures in compact environments such as battery cells.
Innovation Solution
The proposed installation structure includes a measured object support with a guide section and a locking mechanism, allowing the temperature sensor to be installed along a predetermined outer surface of the measured object, with a guided section that engages with the guide section, enabling flexible installation and reduced space requirements by using a rail-like fitting structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring structure (arm section) is used to install the temperature sensor, then the temperature sensor can be securely mounted, but the space required for installation becomes large
Solution Approach 1:
The temperature sensor is divided into multiple sections: a sensor housing section, a guided section with engagement protrusions, and a locking section. This segmentation allows the sensor to be installed in a compact space by engaging with corresponding features on the battery cell surface, eliminating the need for a large spring structure while maintaining secure mounting.
Solution Approach 2:
The guided section and locking section are integrated into the temperature sensor housing, with the locking section positioned to engage with the battery cell surface after the guided section is inserted. This nested configuration reduces the overall installation space required while ensuring reliable mounting through the locking mechanism.
2Volume of moving object
If a compact installation structure is used to reduce space, then installation space is reduced, but the degree of freedom for mounting position options decreases
Solution Approach 1:
The guided section with engagement protrusions and the locking section are designed to work with various battery cell shapes and sizes. The engagement protrusions can fit into different groove configurations, and the locking section can adapt to different surface geometries, providing multiple mounting position options while maintaining a compact installation footprint.
Solution Approach 2:
The locking section is designed to be movable during installation, allowing the temperature sensor to be positioned at different locations on the battery cell. Once positioned, the locking section secures the sensor in place. This dynamic design provides flexibility in mounting position selection while maintaining a compact structure.
3Measurement precision
If the temperature sensor is installed between adjacent measured objects, then temperature measurement capability is improved, but the installation space becomes more constrained
Solution Approach 1:
The temperature sensor is designed with a compact sensor housing section that can be positioned precisely between adjacent battery cells. The guided section and locking section are configured to engage with features on the battery cell surfaces, allowing the sensor to be installed in the narrow space between cells without requiring additional installation space.
