Energy Storage Frame Structure to Prevent Sagging and Rattle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatuses tend to sag when both ends are fixed with the energy storage devices spaced apart from a facing surface, leading to instability and potential rattling or shaking.
Innovation Solution
The energy storage apparatus includes a frame with a first portion extending along the energy storage devices and a second portion extending orthogonally towards the installation surface, which supports the apparatus and reduces sagging by contacting the surface when it starts to sag, enhancing rigidity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If both ends of the energy storage apparatus are fixed with the energy storage devices spaced apart from a facing surface, then ease of installation is improved, but the apparatus sags and stability deteriorates
Solution Approach 1:
The frame structure extends in the second direction (orthogonal to the arrangement direction) toward the facing surface, creating a three-dimensional support structure. This dimensional extension allows the frame to contact the facing surface and provide support without requiring the energy storage devices to be in direct contact with the installation surface, thus maintaining ease of installation while preventing sagging and improving stability.
2Ease of operation
If the energy storage devices are spaced apart from the facing surface, then ease of installation is improved, but rigidity deteriorates causing sagging
Solution Approach 1:
The frame acts as an intermediary structure between the energy storage devices and the facing surface. It provides mechanical support and maintains rigidity through its extended structure that contacts the facing surface, while allowing the energy storage devices to remain spaced apart from the surface for easier installation.
3Stability of the object's composition
If additional support members are added to prevent sagging, then stability is improved, but device complexity increases
Solution Approach 1:
The frame structure performs multiple functions: it holds the energy storage devices in position, provides structural support to prevent sagging, and contacts the facing surface for stability. By integrating these functions into a single structure rather than adding separate support members, the invention improves stability without significantly increasing device complexity.

AI summary
In an embodiment, an energy storage apparatus includes plural energy storage devices arranged in a first direction, and a frame arranged along the energy storage devices. Each of the energy storage devices has an outer surface facing in a second direction orthogonal to the first direction. The frame has a first portion extending in the first direction along the outer surface, and a second portion extending in the second direction toward a facing surface on which the energy storage apparatus is installed, from at least a part of the first portion.
