Vehicle Battery Support With V-Shaped Member For Impact Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs fail to effectively distribute and transmit forces applied during impacts, such as side or front collisions, which can lead to deformation of the vehicle structure and potential intrusion into the passenger cabin.
Innovation Solution
A battery support assembly comprising a tray with intersecting beams and a V-shaped member that distributes force applied during impacts through multiple vehicle components, including the subframe and frame, reducing deformation and intrusion into the passenger cabin.

Engineering Contradiction Analysis
1Strength
If a simple battery support structure is used, then manufacturing cost and device complexity are reduced, but force distribution capability and structural strength during impact are insufficient
Solution Approach 1:
The battery support structure is segmented into multiple functional components: a support tray for battery placement, intersecting beams (first and second beams) for force distribution, and a V-shaped member for additional structural reinforcement. Each segment performs a specific function in the force distribution network, allowing the complex structure to be built from simpler modular elements that can be manufactured and assembled separately.
Solution Approach 2:
The intersecting beams are arranged in multiple dimensions to create a three-dimensional force distribution network. The first beams extend in one direction while the second beams extend perpendicular to them, creating a grid-like structure that distributes forces across multiple spatial dimensions. This dimensional approach allows force distribution without requiring excessive material in any single direction.
2Stability of the object's composition
If no additional force distribution components are added, then device complexity is low, but deformation resistance during side or front impact is insufficient
Solution Approach 1:
The V-shaped member is pre-positioned with its end at the support tray and legs extending to the subframe before any impact occurs. This preliminary configuration creates a pre-loaded structural framework that is ready to distribute forces immediately upon impact. The V-shape geometry provides inherent mechanical advantage for force distribution, and the pre-established connection paths ensure that impact forces are routed through multiple components from the moment of contact.
Solution Approach 2:
The structure is designed to convert the harmful impact force into beneficial distributed stresses across multiple structural components. The intersecting beams and V-shaped member are arranged so that impact forces create compressive and tensile stresses that strengthen the overall structure rather than causing failure. The force distribution network transforms the concentrated harmful impact into distributed beneficial loads that the structure is designed to handle.
3Object-affected harmful factors
If force is not distributed across multiple components, then device complexity is reduced, but passenger cabin intrusion during impact increases
Solution Approach 1:
The intersecting beams and V-shaped member act as intermediary elements between the battery support tray and the vehicle subframe. These intermediaries absorb and distribute impact forces before they can reach the passenger cabin, creating multiple force transmission paths that prevent direct force transfer to vulnerable areas. The V-shaped member specifically serves as a mechanical intermediary that leverages its geometry to distribute forces across wider areas of the subframe.
