EV Battery Removal Reinforcing Frame for Temporary Chassis Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of a battery assembly in electric vehicles compromises the structural integrity of the vehicle, necessitating it to be kept immobile on a lift until reinstallation, which prevents other vehicles from being repaired.
Innovation Solution
A reinforcing frame structure that temporarily couples to the battery assembly mounting apertures, providing longitudinal, transverse, and torsional rigidity, allowing the vehicle to be moved and maintained without reinstallation of the battery assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the battery assembly is removed from the vehicle, then access to the battery assembly is provided for diagnosis and correction, but the structural integrity of the vehicle is compromised and the vehicle cannot be moved
Solution Approach 1:
A reinforcing frame structure serves as an intermediary component that temporarily replaces the battery assembly in the vehicle frame. This frame couples to battery assembly mounting apertures and provides structural support, enabling the vehicle to maintain integrity and be moved while the battery assembly is removed for repair work.
2Ease of repair
If the battery assembly is removed from the vehicle, then repair work can be performed on the battery assembly, but the vehicle must remain immobile on a lift
Solution Approach 1:
The reinforcing frame acts as a temporary structural substitute that allows the vehicle to be taken off the lift and moved to different locations. This eliminates the need to keep the vehicle stationary on a lift throughout the entire repair process, reducing overall downtime.
Solution Approach 2:
The solution separates the structural support function from the battery assembly function. The reinforcing frame assumes the structural support role temporarily, while the battery assembly is independently removed and repaired elsewhere, allowing parallel processing of repair tasks.
3Ease of repair
If the battery assembly is removed from the vehicle, then the issue with battery components can be diagnosed and corrected, but the lift cannot be used for other vehicles
Solution Approach 1:
By separating the structural support function (provided by the reinforcing frame) from the battery assembly, the battery can be removed and repaired on separate equipment while the vehicle is moved. This allows the lift to be freed up for other vehicles, increasing overall shop productivity.
4Weight of moving object
If the battery assembly is incorporated into the frame to provide structural support, then weight is minimized and manufacturing is simplified, but the entire battery assembly must be removed when battery issues arise
Solution Approach 1:
The reinforcing frame serves as a temporary intermediary structure that replicates the structural support previously provided by the battery assembly. This allows the battery to be completely removed for repair while maintaining vehicle structural integrity, making the battery accessible without compromising vehicle stability.

AI summary
A reinforcing frame structure that bolts or otherwise couples in place of a battery assembly of a vehicle, such as an electrically powered vehicle, and provides sufficient longitudinal, transverse, and torsional rigidity to the vehicle when the battery assembly is removed from the vehicle. The reinforcing frame structure can be releasably attached to the vehicle after the battery assembly is removed. This allows the vehicle to be taken off a lift and moved while minimizing potential damage to the vehicle while the battery assembly is removed from the vehicle.
