Temperature Sensor Attachment Structure for Battery Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing attachment structure of temperature sensors in battery modules has an unstable fitting force due to the M-shaped arm-shaped spring parts, leading to inconsistent contact with the battery surface, which affects the stability of the temperature detection.
Innovation Solution
The proposed attachment structure incorporates arm-shaped elastic parts with a flat surface that are pressed by an attachment tool, allowing for stable engagement with the housing case and preventing the elastic parts from opening outward, ensuring secure contact with the battery surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If arm-shaped spring parts are bent in M shape and angled with respect to pressing force, then the temperature sensor can be pressed against the battery surface, but the area to which fitting force is applied is small causing unstable pressing force
Solution Approach 1:
The elastic part is designed with a flat surface at a specific location to concentrate and stabilize the pressing force application area. This local modification ensures that the attachment tool presses uniformly on the flat surface, preventing opening of the elastic parts and maintaining stable fitting force throughout the assembly process.
2Ease of operation
If arm-shaped spring parts are used to press the temperature sensor, then the sensor can be held against the battery surface, but the elastic parts open during assembly causing unstable contact
Solution Approach 1:
The flat surface on the elastic part acts as an intermediary between the attachment tool and the elastic part structure. This flat surface provides a stable interface that prevents the elastic parts from opening during assembly, ensuring consistent contact between the temperature sensor and battery surface throughout the manufacturing process.
