Battery Module Mounting Arrangement for Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting systems for battery modules in electrically propelled vehicles require complex and expensive fastening arrangements or time-consuming methods due to shifting tolerances between the battery modules and the housing, necessitating space for easy sliding, which complicates secure fixation.
Innovation Solution
A mounting arrangement comprising a fastening element, mounting element, and compensating element that allows for adjustable engagement and compensation of gaps from the outer side of the housing, enabling secure fixation without welding and preventing rotation, using threaded connections and engagement mechanisms for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets or complex fastening systems are used to address shifting tolerances, then the battery module can be securely fixedated, but the device complexity increases
Solution Approach 1:
The mounting arrangement is divided into distinct functional elements: a mounting element fixed to the housing, a compensating element that absorbs dimensional variations, and a fastening element for securing. This segmentation allows each component to perform its specific function independently, simplifying the overall system while ensuring reliable fixation despite shifting tolerances.
Solution Approach 2:
The compensating element acts as an intermediary between the mounting element and the battery module. It absorbs dimensional variations and misalignments, allowing the fastening element to securely fixate the battery module without requiring complex adjustment mechanisms. The compensating element mediates the tolerance issues, eliminating the need for complex fastening systems.
2Ease of operation
If space is required around the battery module for easy sliding, then the battery module can be easily installed, but the area available for secure fixation is reduced
Solution Approach 1:
The mounting element is fixed to the housing in advance, and the compensating element is pre-assembled with it. This preliminary action allows the battery module to be easily slid into position without requiring complex alignment procedures. The pre-assembled mounting arrangement guides the battery module into its correct position, maintaining ease of installation while maximizing the use of available space for fixation.
3Reliability
If conventional fastening methods are used that require mating surfaces to be in contact, then the battery module can be securely mounted, but the mounting process becomes time-consuming
Solution Approach 1:
The compensating element serves as a mediator that eliminates the need for precise mating surface contact. It absorbs dimensional variations and allows the fastening element to secure the battery module quickly without requiring time-consuming alignment and adjustment of mating surfaces. This intermediary component maintains secure mounting while dramatically reducing mounting time.
