Electric Connection Box Adhering Portion Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connection boxes attached to vehicle battery packs are difficult to remove safely due to hardened adhesives, which can lead to deformation or damage when forcibly pulled.
Innovation Solution
The electric connection box design features a housing with an adhering portion that has a reduction portion reduced in area toward one end, allowing for easy removal by pulling on a handle, and includes ribs to prevent stress concentration and deformation during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If adhesive is used to attach the electric connection box to the cooling mechanism, then thermal conductivity and contact area increase, but removal difficulty increases due to hardening over time
Solution Approach 1:
The adhering portion is divided into a first adhering portion with a larger area and a second adhering portion with a smaller area. This segmentation allows the first adhering portion to provide sufficient thermal conductivity and contact area, while the second adhering portion maintains easier removability due to its reduced size and lower adhesion strength.
2Ease of operation
If force is applied to remove the electric connection box from the cooling mechanism, then removal is achieved, but deformation or damage occurs to the electric connection box
Solution Approach 1:
The adhering portion has non-uniform local quality with the first adhering portion having a larger area for strong adhesion and thermal contact, while the second adhering portion has a smaller area for easier removal. This local quality variation ensures that removal force can be applied without causing deformation or damage to the entire electric connection box structure.
