Battery Module Groove Connection and Spring Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems face challenges in arranging battery modules in a space-saving manner while ensuring secure connections to the battery housing, particularly in compact designs where modules need to be easily replaceable and securely attached to prevent unintentional loosening.
Innovation Solution
The battery system employs a tongue and groove connection mechanism with a screwing mechanism, where the tongue and connecting means are arranged in the groove, allowing for compact arrangement and secure attachment of battery modules to the housing, with a spring covering the screw to prevent loosening, and integrated cooling fluid channels for efficient cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If battery modules are arranged in a compact design with tongue-and-groove connections, then space utilization is improved, but connection security and resistance to unintentional loosening deteriorate
Solution Approach 1:
The connecting element is received within the groove of the battery module housing, creating a nested structure where the connector is partially embedded in the groove. This nesting arrangement saves space while maintaining connection security through the integrated groove-connector interface.
Solution Approach 2:
The spring element is arranged to overlap with the connecting element in the direction normal to the housing surface, utilizing the third dimension (depth) rather than only lateral spacing. This dimensional arrangement allows both components to coexist in a compact volume while the spring provides securing force to prevent unintentional loosening.
2Ease of operation
If connecting elements are arranged outside the groove for easy access, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The screw is spaced apart from the groove in the direction normal to the housing surface, allowing the screw head to be accessible from the outside while the connecting element remains received in the groove. This dimensional separation enables easy screw access without exposing the connecting element, maintaining a clean integrated appearance.
3Volume of moving object
If multiple components are arranged in overlapping positions, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connection mechanism is divided into functionally distinct segments: the groove provides the receiving structure, the connecting element provides the mechanical connection, the spring provides the securing force, and the screw provides the fastening. This segmentation allows each component to be manufactured and assembled independently with standard tolerances, reducing overall manufacturing precision requirements despite the compact overlapping arrangement.
