Motor Vehicle Battery Damping Element with Channel Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern electric and hybrid motor vehicles, the compact design required for energy storage units above the subfloor, due to the presence of various lines, leads to structural space constraints and protection issues, limiting the height and energy capacity of the battery.
Innovation Solution
The energy storage unit is mounted on a sheet-like damping element with channel-shaped openings to guide the lines, providing damping and spacing to protect both the unit and the lines from peak forces, allowing for a more compact and efficient arrangement that increases the battery's height and energy content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective measures are introduced between the lines and the energy storage unit, then the components are protected against each other, but the available structural space is reduced and the height of the energy storage unit is affected
Solution Approach 1:
The damping element combines multiple functions into a single component: it provides damping for the energy storage unit, creates defined pathways for lines through channel-shaped openings, and provides protective spacing between lines and the energy storage unit. This integration eliminates the need for separate protective structures that would reduce structural space.
Solution Approach 2:
The damping element serves multiple purposes simultaneously: it acts as a vibration-damping support for the energy storage unit, provides structured routing for lines via integrated channel openings, and creates protective spacing between components. This multi-functionality resolves the contradiction by achieving protection without sacrificing height.
2Volume of moving object
If the battery is designed as narrow as possible to fit with lines, then it can be installed in the available space, but the structural space and possible height are limited
Solution Approach 1:
The channel-shaped openings in the damping element provide defined three-dimensional pathways for lines to route through and alongside the energy storage unit. This spatial organization in multiple dimensions allows the battery to achieve greater height without lines interfering with the available structural space.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively dampens subfloor-induced forces, protects the lines and energy storage unit, and optimizes structural space, enabling a higher energy capacity battery while maintaining protection against peak forces and vibrations.
Implementation Method 1
the damping element has at least one channel-shaped opening through which at least one of the lines running above the subfloor is led
Implementation Method 2
corresponding peak forces caused by the subfloor are damped and do not have detrimental effect on the energy storage unit
