Energy Storage Housing Side Wall Deflection Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing energy storage apparatuses suffer from side wall deflection issues due to unsupported regions, leading to increased assembly difficulties and manufacturing costs, as well as reduced productivity and appearance quality.
Innovation Solution
Incorporating a support member that connects to the side walls in specific regions, providing additional support and minimizing deflection, which can be achieved with a second partition plate functioning as both a support and insulation component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the outer housing is designed with a large surface area to house multiple battery cells, then the housing capacity is improved, but the side walls become more prone to deflection due to lack of support
Solution Approach 1:
The side wall is divided into multiple regions: a first region that is supported by battery cells and a second region that extends beyond the battery cells. This segmentation allows the housing to maintain large volume while identifying specific areas that require additional support structures to prevent deflection.
Solution Approach 2:
A support member is introduced as an intermediary element between the second region of the side wall and the interior space. This support member provides the necessary structural reinforcement to prevent deflection in the unsupported region without reducing the overall housing capacity.
2Stability of the object's composition
If support members are added to prevent side wall deflection, then structural stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The support member is designed to serve multiple functions: it provides structural support to prevent side wall deflection, and it can also serve as a mounting structure for fastening the outer housing to the base or as part of the insulation system. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The support member is merged with either the outer housing or the base structure, creating an integrated component rather than a separate part. This merging reduces the total number of components and simplifies the manufacturing process while still providing the necessary structural support.
3Adaptability or versatility
If the side wall extends beyond the battery cell case, then housing flexibility and design freedom are improved, but deflection risk increases due to unsupported regions
Solution Approach 1:
The side wall is divided into a first region that aligns with the battery cell case and a second region that extends beyond it. This segmentation allows the design to maintain flexibility in the second region while the first region provides structural stability through its alignment with the supported battery cells.
Solution Approach 2:
A support member is positioned in the second region to act as an intermediary structural element. This support member enables the side wall to extend beyond the battery cell case for design flexibility while preventing deflection in the unsupported extension region.

AI summary
An energy storage apparatus including: an energy storage device; and an outer housing including a bottom surface, a side wall extending from the bottom surface in a first direction that intersects the bottom surface, and a support member that supports the side wall. An end of the side wall in the first direction is positioned in a first region that is further in the first direction than an end of a case of the energy storage device in the first direction. The support member is connected to the side wall in at least the first region and supports the side wall.
