Hybrid Battery Mount Bracket for Upright Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mounting HEV battery packages upright behind the rear seat back in hybrid vehicles is ergonomically challenging and costly due to the need for body reinforcements, making it difficult to load and install the battery package efficiently.
Innovation Solution
A battery package mount bracket system comprising a body-mounted bracket with spaced-apart attachment flanges and an HEV-mounted bracket, featuring a main plate, transverse flange, and side flange, allowing for detachable attachment of the HEV battery package, facilitating easier loading and installation by enabling attachment to the vehicle's body pillar with fasteners and U-nuts, and providing a guide ramp for safe positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the HEV battery package is mounted upright behind the rear seat back, then the space utilization and functional requirements are optimized, but the ease of operation deteriorates due to ergonomic difficulties in loading the package through the trunk
Solution Approach 1:
The mounting system is divided into two separate brackets: a body-mounted bracket that attaches to the vehicle body and an HEV-mounted bracket that attaches to the battery package. This segmentation allows the battery package to be loaded through the trunk and then detached from the body-mounted bracket, making the loading operation ergonomically feasible while maintaining the upright mounting position for optimal space utilization
Solution Approach 2:
The body-mounted bracket acts as an intermediary between the vehicle body and the HEV battery package. It provides a mounting interface that allows the battery package to be positioned upright behind the rear seat back while enabling easy loading through the trunk by temporarily attaching to the body structure during installation
2Area of stationary object
If the HEV battery package is mounted upright behind the rear seat back, then the space utilization is optimized, but the device complexity increases due to the need for body reinforcements
Solution Approach 1:
The mounting system separates the reinforcement requirements from the vehicle body by using a standalone body-mounted bracket. This bracket can be designed with the necessary reinforcement features independently, avoiding the need to reinforce the vehicle's existing body structure, thus reducing overall device complexity while maintaining optimal space utilization
Solution Approach 2:
The mounting function is extracted from the vehicle body structure itself and implemented through a separate body-mounted bracket. This extraction eliminates the need for body reinforcements, simplifying the overall system while still enabling upright mounting of the battery package for optimal space utilization
3Adaptability or versatility
If the HEV battery package is mounted upright behind the rear seat back, then the functional requirements are optimized, but the weight increases due to added body reinforcements
Solution Approach 1:
The mounting system is segmented into separate brackets that can be independently designed and optimized. The body-mounted bracket carries the reinforcement requirements, while the HEV-mounted bracket attaches to the battery package. This segmentation fulfills functional requirements for upright mounting while minimizing the need for additional vehicle body reinforcements, thereby reducing added weight
Solution Approach 2:
The reinforcement function is extracted from the vehicle body and consolidated into the body-mounted bracket. This extraction allows the reinforcements to be localized and optimized specifically for the mounting function, reducing the overall weight added to the vehicle while still meeting functional requirements for upright battery package mounting
4Ease of operation
If the HEV battery package is mounted flat on the trunk floor, then the ease of operation is improved for loading, but the space utilization deteriorates
Solution Approach 1:
The mounting system uses two separate brackets that enable the battery package to be loaded through the trunk in a horizontal position and then transferred to an upright position behind the rear seat back. This segmentation of the mounting function allows easy loading while achieving optimal space utilization in the upright position
Solution Approach 2:
The body-mounted bracket is pre-installed on the vehicle body to provide a mounting interface. This preliminary action allows the battery package to be easily loaded through the trunk and then attached to the bracket, facilitating the transition from horizontal loading to vertical mounting for optimal space utilization
