Holding Element Strut for Lateral Crash Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles, particularly electric motor vehicles, face challenges in facilitating lateral displacement during collisions, such as the 'small overlap test', where conventional front axle carriers do not effectively absorb kinetic energy, leading to inadequate lateral movement.
Innovation Solution
A holding apparatus with a holding element and strut section that extends in the vehicle front and transverse direction, acting as a 'shelf' to introduce momentum and facilitate lateral sliding by absorbing crash forces, while securely holding electric components like batteries and compressors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional front axle carriers are used to hold electric components, then the holding function is provided, but the lateral displacement capability during collision is insufficient
Solution Approach 1:
The holding element is designed to serve dual functions: holding electric components (original function) and facilitating lateral displacement during collision (new function). The strut section extending in the vehicle transverse direction enables the holding element to act as a lateral force transmission path, allowing the same component to contribute to both component mounting and crash behavior.
Solution Approach 2:
The holding element is designed with a strut section that extends not only in the vehicle front direction but also in the vehicle transverse direction. This three-dimensional configuration allows the holding element to transmit forces in multiple directions, particularly enabling lateral force transmission during collision that was not possible with conventional front-direction-only carriers.
2Reliability
If the strut section extends in the vehicle transverse direction to facilitate lateral sliding, then the momentum introduction capability is improved, but the holding element design becomes more complex
Solution Approach 1:
The holding element integrates multiple functions including component holding, lateral force transmission, and momentum introduction. By designing the strut section to extend in both vehicle front and transverse directions, the same component structure serves as both a mounting bracket and a crash force transmission path, eliminating the need for separate structures.
Solution Approach 2:
The holding element merges the functions of component support and collision force management into a single integrated structure. The strut section combines the roles of structural support for electric components and force transmission path for lateral displacement, reducing overall system complexity despite the enhanced functionality.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the collision behavior of electric motor vehicles by enabling effective lateral displacement on obstacles during crashes, improving safety by absorbing and redirecting impact forces into the vehicle body.
Implementation Method 1
the holding element contributing to introducing a momentum (M) which originates as a result of the impact (I) with the obstacle (55) into the rigid or hardly deformable vehicle body (60) in the Y-direction or vehicle transverse direction
Implementation Method 2
in the case of the 'small overlap test', a frontal impact with an overlap of 25% at 64 km/h is carried out

AI summary
A holding device for electrical components of a motor vehicle, preferably an electrical motor vehicle, includes a holding element that is designed to hold one or more electrical components of the vehicle. The holding element has a holding section for holding the one or more electrical components, and a strut section, which extends from the holding section. The holding element is designed such that when the holding element is attached to the motor vehicle as intended, the strut section extends in the vehicle front direction and vehicle transverse direction to a vehicle front section and is at a predefined angle to an axis oriented in the vehicle front direction.
