Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dimensional deviations at fastening points of the battery control unit housing can lead to damage during mounting, compromising the reliable operation of the traction battery.
Innovation Solution
The method involves reworking spacer elements on the battery housing using an ablative method to ensure a consistent height for fastening, thereby compensating for dimensional deviations and preventing damage to the battery control unit during mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spacer elements are used to fasten the battery control unit to the battery housing, then the battery control unit is securely mounted and protected, but dimensional deviations at the fastening points can cause the spacer elements to be too long or too short, leading to damage during mounting
Solution Approach 1:
The spacer elements are pre-fastened to the battery housing before the battery control unit is mounted. This preliminary action allows the fastening points to be established and secured in advance, ensuring proper positioning and preventing damage during the subsequent mounting of the battery control unit.
Solution Approach 2:
The spacer elements act as intermediary components between the battery housing and the battery control unit. They provide a buffering interface that absorbs dimensional deviations and prevents direct transmission of mechanical stress to the battery control unit, thereby avoiding damage while maintaining secure mounting.
2Strength
If the battery control unit is fastened directly to the battery housing at multiple fastening points, then secure mounting is achieved, but dimensional deviations cause tensioning and potential damage to the battery control unit housing
Solution Approach 1:
The spacer elements serve as intermediary components that distribute and buffer the mechanical forces between the battery housing and the battery control unit. By introducing these intermediate elements, the direct transmission of tensile stresses is reduced, preventing housing tensioning while maintaining a secure connection through multiple fastening points.

AI summary
A method fastens a battery control unit to a battery housing. At least one spacer is fastened to the battery housing, and the battery control unit is fastened to the battery housing at least via the spacer. After fastening the spacer to the battery housing, the spacer is reworked by way of an ablative method on a side which faces the battery control unit to a height which is required for fastening the battery control unit.
