Battery Connection Module Temporary Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection modules for electric storage elements face inefficiencies in temperature detection due to increased electrical resistance and require manual fixing by vehicle manufacturers, which reduces work efficiency when the temperature detection portion is not pre-fixed to the conductor or insulating member.
Innovation Solution
A connection module with a temporary locking mechanism that detachably secures the temperature detection portion near the insulating member, allowing for efficient fixing and rotation assistance via a rotary shaft and groove configuration, reducing hand movement and interference with the conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature detection portion is disposed between the connection member and the electrode terminals, then the temperature can be detected, but the electrical resistance between the connection member and the electrode terminals increases
Solution Approach 1:
The patent introduces a temperature detection portion as an intermediary component that detects temperature without significantly interfering with electrical conduction. The detection portion is designed to minimize its impact on the electrical path between the connection member and electrode terminals, allowing temperature monitoring while maintaining acceptable electrical resistance levels.
2Ease of manufacture
If the temperature detection portion is fixed to the insulating member, then the fixing work can be done in advance, but the temperature detection portion cannot be disposed on the conductor being held by the insulating member
Solution Approach 1:
The patent divides the assembly into separate functional components: the insulating member with holding portion that secures the conductor, and the temperature detection portion that can be independently positioned on the conductor. This segmentation allows the detection portion to be fixed to the insulating member in advance while still enabling proper disposal on the conductor during assembly.
3Adaptability or versatility
If the connection module and conductor are separately delivered, then the manufacturer cannot fix the temperature detection portion to the conductor in advance, but the work of fixing must be performed by the vehicle manufacturer's worker
Solution Approach 1:
The patent enables preliminary fixing of the temperature detection portion to the insulating member during connection module manufacturing, even when the conductor is not yet attached. The holding portion and temporary locking mechanism allow the detection portion to be pre-positioned and secured, so that when the conductor is later assembled, the detection portion is already in place, eliminating the need for additional fixing work by the vehicle manufacturer.
4Ease of operation
If the temperature detection portion is at a position distant from the insulating member, then the temperature detection portion can be disposed on the conductor, but the distance of hand motion becomes long and work efficiency is reduced
Solution Approach 1:
The patent merges the temperature detection portion with the insulating member through the holding portion structure, positioning the detection portion in close proximity to the insulating member. This integration allows the detection portion to be disposed on the conductor while minimizing hand motion distance, as the detection portion is already positioned near the insulating member where the conductor is held.
