Battery Core Sampling Support Structure for Vibration-Stable Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery systems, the sampling wire harness is not fixed, leading to loose connections between the sampling wire harness and battery cores due to vibration, resulting in inadequate collection of battery core information.
Innovation Solution
A battery core unit with a sampling structure featuring notches and limiting strips, and a fixing support with protrusions and conductive sheets, which securely arranges the sampling structure on the fixing support to reduce shaking and enhance connection reliability between the sampling structure and battery cores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sampling wire harness is arranged inside the battery to collect signals, then the battery core information can be collected, but the sampling wire harness is not fixed and shakes during vibration, causing loose connections
Solution Approach 1:
The sampling structure is divided into multiple segments including the sampling wire harness, fixing support, limiting strips, and spacing regions. Each segment performs a specific function: the sampling wire harness collects signals, the fixing support provides mounting positions, the limiting strips constrain movement, and the spacing regions maintain proper distances. This segmentation allows the system to achieve both flexibility in signal collection and stability in connection maintenance.
Solution Approach 2:
The fixing support acts as an intermediary component between the sampling wire harness and the battery core. It provides a stable mounting structure with limiting strips that prevent the sampling wire harness from shaking during vibration, while still allowing it to maintain electrical connection with the battery core groups. This intermediary structure resolves the contradiction by providing both fixation and flexibility.
2Reliability
If the sampling wire harness is fixed securely to reduce shaking, then connection reliability improves, but the structure becomes more complex
Solution Approach 1:
Multiple functions are merged into the fixing support structure: it provides mounting positions for the sampling wire harness, incorporates limiting strips to prevent shaking, and creates spacing regions to maintain proper distances. By combining these functions into a single integrated component rather than separate elements, the structure achieves high connection reliability without excessive complexity.
Solution Approach 2:
The fixing support serves multiple purposes simultaneously: it fixes the sampling wire harness in position, provides limiting strips to prevent movement during vibration, maintains spacing between components, and supports the overall sampling structure. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving secure fixation.
