Segmented Holding Frame for Stacked Electric Storage Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric storage devices in vehicles face challenges in efficiently utilizing space and facilitating easy replacement of storage modules while maintaining compactness and structural integrity.
Innovation Solution
The electric storage device employs a holding frame divided into multiple frame members, which are fixed to a mounting plate, allowing second storage modules to be stacked above first storage modules, with a design that enables efficient use of vehicle space and easy replacement of modules by separating the frame members.

Engineering Contradiction Analysis
1Volume of moving object
If storage modules are arranged in two upper and lower stages to efficiently utilize space, then space utilization is improved, but device complexity increases
Solution Approach 1:
The holding frame is divided into a first frame member and a second frame member that can be separated from each other. The first frame member holds the upper storage module while the second frame member provides support below. This segmentation allows the upper storage module to be replaced independently without removing the entire holding frame, thus simplifying maintenance operations while maintaining the two-stage stacked configuration for efficient space utilization.
2Strength
If a platelike support member is laid across both ends of a lower storage module with support legs, then structural integrity is improved, but ease of operation deteriorates
Solution Approach 1:
The holding frame is divided into a first frame member and a second frame member that can be separated from each other. The first frame member holds the upper storage module while the second frame member provides support below. This segmentation allows the upper storage module to be replaced independently without removing the entire holding frame, thus simplifying maintenance operations while maintaining the two-stage stacked configuration for efficient space utilization.
3Power
If multiple storage cells are stacked to set output voltage high, then power output is improved, but device complexity increases
Solution Approach 1:
The holding frame is divided into a first frame member and a second frame member that can be separated from each other. The first frame member holds the upper storage module while the second frame member provides support below. This segmentation allows the upper storage module to be replaced independently without removing the entire holding frame, thus simplifying maintenance operations while maintaining the two-stage stacked configuration for efficient space utilization.

AI summary
An electric storage device includes first storage modules, a second storage module, an attachment part, and a holding frame. The first storage modules include one first storage module and another first storage module. The attachment part has an attachment surface on which the first storage modules are mounted. The holding frame is disposed between the one first storage module and the second storage module to hold the second storage module. The holding frame includes a first frame member and a second frame member. The first frame member has a first bottom portion connected to the attachment surface. The second frame member has a second bottom portion connected to the attachment surface such that the second bottom portion is disposed between the attachment surface and a lower part of the another first storage module.
