Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting traction batteries in vehicles are complex and inefficient, requiring careful lowering and fitting into a cage-like frame, which complicates both production and maintenance processes.
Innovation Solution
A system featuring front and rear bracket members with sliding surfaces and sliders attached to the battery, allowing for easy horizontal placement and removal using a pallet lifter, with additional stabilizing and protective elements for secure holding and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cage-like frame structure is used to mount the battery, then the battery is securely held in place, but the installation process becomes complex and time-consuming requiring careful lowering and sliding operations
Solution Approach 1:
The cage-like frame is segmented into individual bracket members (front bracket, rear bracket, side brackets) that are spaced apart and connected by stabilizing elements. This segmentation maintains the secure holding function while simplifying the installation process, as batteries can be mounted using simple lifting operations rather than complex lowering and sliding procedures
Solution Approach 2:
Stabilizing elements serve as intermediaries connecting the spaced-apart bracket members to the vehicle frame. These stabilizing elements provide structural rigidity and ensure proper positioning without requiring the complex interlocking mechanisms of a full cage-like frame, thus reducing device complexity while maintaining reliability
2Reliability
If a cage-like frame structure is used to mount the battery, then the battery is securely held in place, but the installation time increases due to complex operations
Solution Approach 1:
By dividing the mounting system into separate bracket members with stabilizing elements rather than a single integrated cage-like frame, the installation process is simplified to basic lifting operations. This segmentation enables faster installation while maintaining secure battery holding through the distributed bracket structure
Solution Approach 2:
Instead of requiring the battery to be lowered into and slid along a cage-like frame (complex sequence), the invention inverts the approach by using spaced bracket members that allow the battery to be simply lifted into position. This reversal of the installation sequence dramatically reduces time loss while maintaining securing reliability
3Ease of operation
If bracket members are spaced apart rather than forming a continuous frame, then installation is simplified, but structural stability may be compromised
Solution Approach 1:
Stabilizing elements act as intermediaries connecting the spaced-apart bracket members, providing the necessary structural stability. These elements transfer loads between brackets and ensure proper positioning, compensating for the gaps between spaced members while maintaining ease of operation during installation
Solution Approach 2:
The stabilizing elements provide localized reinforcement at critical connection points between bracket members. This local quality enhancement ensures structural stability where needed while maintaining the overall spaced-apart configuration that enables simple installation operations

AI summary
The invention relates to a system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.
