Battery Housing Flange Alignment via Positioning Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery manufacturing process faces challenges in quickly aligning and positioning the battery housing and cover plate due to structural limitations, leading to inefficiencies in assembly.
Innovation Solution
The method involves creating a first and second housing with flanges and positioning parts that allow for quick alignment and welding, utilizing positioning holes, notches, or protrusions to facilitate efficient assembly, and subsequently cutting the flanges to reduce the occupied area and enhance connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional battery housing assembly methods are used, then the structural integrity is maintained, but the alignment efficiency between housing and cover plate is low
Solution Approach 1:
Positioning parts (positioning holes, positioning notches, or positioning protrusions) are pre-formed on the housing and cover plate during the stamping process, enabling quick alignment without requiring additional alignment operations during assembly
Solution Approach 2:
The patent replaces complex mechanical alignment procedures with simple geometric positioning features that automatically guide the relative position of housing and cover plate through shape complementarity
2Reliability
If flanges are extended outward for welding, then the welding connection is reliable, but the occupied area increases
Solution Approach 1:
The flange is designed with different functional zones: an extended welding portion for reliable connection and a reduced positioning portion for minimal area occupation, optimizing both welding reliability and space efficiency
