Battery Pack Support Straps for Impact-Resistant Structural Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs in vehicles are vulnerable to structural damage from impacts, particularly in off-road conditions, leading to potential fracturing or breaking of structural members.
Innovation Solution
The use of straps with asymmetric and symmetric designs, integrated with structural members, to counter and offset forces applied to the battery pack, minimizing impact and preventing bending or fracturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If structural members are used to support the battery pack, then the structural strength is improved, but the vulnerability to impact forces worsens
Solution Approach 1:
The patent applies flexible straps made of metal or polymer material to reinforce the structural members. These straps wrap around the structural members and are secured with fasteners, creating a flexible reinforcement system that can absorb and distribute impact forces. The flexible nature of the straps allows them to deform under impact while maintaining structural integrity, preventing fracturing of the structural members during off-road events.
2Force
If straps are integrated with structural members, then the resistance to impact forces is improved, but the device complexity worsens
Solution Approach 1:
The reinforcement system is divided into discrete components: individual straps, fasteners, and structural members. Each strap can be independently installed and removed, allowing for modular assembly and maintenance. The straps are positioned at specific locations along the structural members where impact forces are most likely to occur, providing targeted reinforcement without requiring complete structural redesign.
Solution Approach 2:
The straps act as intermediary elements between the structural members and the impact forces. Instead of directly reinforcing the structural members with rigid attachments, the flexible straps serve as a mediator that absorbs and distributes the impact forces across multiple attachment points, reducing the stress concentration on any single structural member.

AI summary
A battery pack may include one or more structural members, with at least some of the structural members coupled with one or more straps. The straps are designed and positioned to support the structural members. For example, in the event of an applied force to the battery pack, the applied force may cause the straps to bend. However, the straps may be pulled in tension as a result, and provide a counterforce. The counterforce provided by the straps may provide the structural members assembly with added resistance to withstand the impact from the applied force.
