Battery Wiring Module Cover Retention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery wiring modules, the covers for storage grooves are prone to coming off due to the shorter length of intermediate storage grooves, which can lead to improper alignment and assembly issues.
Innovation Solution
The battery wiring module design includes a housing with first and second storage grooves extending in the same direction, side by side, and a third storage groove in communication with both, featuring a third cover with an underside surface and an outer surface, and a first cover with an abutting portion that restricts the third cover's movement, ensuring it remains in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a short third storage groove is provided between the first and second storage grooves to allow wire crossing, then wire routing flexibility is improved, but the third cover becomes prone to coming off
Solution Approach 1:
The abutting portion acts as an intermediary mechanical element between the first cover and the third cover. It provides a bridging structure that transfers and distributes the retaining force from the longer first storage groove to the shorter third storage groove, enabling the third cover to be retained reliably despite its shorter length
Solution Approach 2:
The abutting portion is pre-configured on the first cover to proactively prevent the third cover from coming off. By having this retaining structure in place before assembly is complete, the design anticipates and prevents the potential failure mode of the short third cover detaching during operation

AI summary
Provided is a battery wiring module that can suppress a case in which a cover comes off. The battery wiring module includes a housing having a wire storage groove that stores multiple wires. The housing includes a first storage groove and second storage grooves that both extend in an X direction and are arranged side by side in a Y direction orthogonal to the X direction, and third storage grooves that are in communication with the first storage groove and the second storage grooves. The housing includes a first cover, second covers, and third covers that respectively cover the first storage groove, the second storage grooves, and the third storage grooves. The first cover has abutting portions that abut on outer surfaces on sides of the third covers opposite to the underside surfaces opposing the third storage grooves.
