Transverse Sliding Guide for Battery Module Impact Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery arrangements in electrified vehicles lack effective mechanisms to distribute and absorb side impact forces efficiently, leading to potential damage and increased weight due to unnecessary reinforcements.
Innovation Solution
A transverse sliding guide system between battery modules, featuring an I-shaped cross-sectional profile and horizontal projections, allows modules to move relative to each other, dispersing impact forces and maintaining structural integrity while reducing weight and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rigid battery arrangements are used, then structural stability is maintained, but side impact forces cannot be effectively distributed and absorbed
Solution Approach 1:
The patent applies the dynamics principle by enabling the battery modules to move relative to each other in the transverse direction through guides. This dynamic capability allows the battery arrangement to adapt during side impacts, distributing impact forces across multiple modules rather than concentrating them in a rigid structure. The modules can slide longitudinally within the battery housing to absorb impact energy while the guides maintain vertical stability.
2Reliability
If additional reinforcement structures are added to protect against side impacts, then safety is improved, but vehicle weight increases
Solution Approach 1:
The patent applies the self-service principle by designing the battery modules themselves to provide impact protection through their ability to move and distribute forces. The modules' inherent design with guides and flexible connections enables them to absorb and distribute side impact forces without requiring additional external reinforcement structures, thus maintaining safety while avoiding increased weight.
3Reliability
If battery modules are fixed rigidly to prevent movement, then structural integrity is maintained, but impact energy cannot be dispersed
Solution Approach 1:
The patent applies the segmentation principle by dividing the battery into multiple independent modules that can move relative to each other. Each module is connected through guides that allow longitudinal movement while maintaining vertical stability. This segmentation enables impact energy to be dispersed across multiple modules through their relative movement, while the overall structural integrity is maintained by the guides and flexible connections.
Solution Approach 2:
The patent applies the dynamics principle by enabling the battery modules to move relative to each other in the transverse direction through guides. This dynamic capability allows the battery arrangement to adapt during side impacts, distributing impact forces across multiple modules rather than concentrating them in a rigid structure. The modules can slide longitudinally within the battery housing to absorb impact energy while the guides maintain vertical stability.
4Reliability
If heavy reinforcement structures are used to protect the battery, then safety is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent applies the self-service principle by designing the battery modules themselves to provide impact protection through their ability to move and distribute forces. The modules' inherent design with guides and flexible connections enables them to absorb and distribute side impact forces without requiring additional external reinforcement structures, thus maintaining safety while avoiding increased weight that would reduce energy efficiency.

AI summary
This disclosure relates to a battery arrangement for an electrified vehicle. In particular, the battery arrangement includes modules which are configured to move relative to one another in a transverse direction. For instance, an example battery arrangement includes a guide, and first and second battery modules. The guide is arranged at least partially between adjacent surfaces of the battery module housings and is configured to permit the first and second battery modules to slide relative to one another in a transverse direction of the electrified vehicle.
