Vehicle Battery Mounting Structure With Switchable Load Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with heavy batteries, the clearance between body supports and the battery creates a gap that hinders the transfer of load and energy during accidents, leading to deformation and damage, and complicates battery mounting and dismounting.
Innovation Solution
A battery arrangement with a receiving space between body supports, featuring a fixing element that bridges the gap in the installed state to form a rigid load path and transitions to a partial or non-bridging state for easy mounting and dismounting, ensuring efficient energy transfer during accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clearance is provided between body supports and battery to enable mounting and dismounting, then ease of operation is improved, but accident safety deteriorates due to inability to transfer load and energy
Solution Approach 1:
The fixing element transitions between two states: in the mounted state it bridges the distance to provide load transfer capability, while in the dismounted state it allows clearance for battery removal. This dynamic transformation resolves the contradiction by making the structural connection conditional rather than fixed.
2Ease of operation
If distance is maintained between body support and battery boundary surface, then ease of operation is improved for battery installation, but load transfer capability in accidents deteriorates
Solution Approach 1:
The fixing element acts as an intermediary component that can either bridge the gap between the body support and battery (providing load transfer) or be positioned to allow clearance (enabling installation). This mediator resolves the contradiction by controlling the presence or absence of direct contact based on operational state.
3Reliability
If fixing element bridges the distance completely in installed state, then accident safety is improved through direct load path, but device complexity increases
Solution Approach 1:
The fixing element changes its positional parameter between two discrete states: fully bridging the distance for load transfer, or positioned to allow clearance for installation. This parameter change approach simplifies the system by using discrete positions rather than continuous adjustment mechanisms.

AI summary
A battery arrangement in a vehicle including at least two body supports of the vehicle, between which there is a receiving space, at least one battery, which is arranged at least in some areas in the receiving space between the body supports. At least on one side of the battery there is a distance between a body support and a boundary surface of the battery, and at least one fixing element which bridges or fills the distance in an installed state and is transferable to a mounting state in which the fixing element does not or only partially bridges or fills the distance.
