High-Rigidity Member for Energy Storage Case Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatuses may not adequately protect energy storage devices from external forces, particularly when concentrated forces are applied, leading to potential damage and deformation of the outer case and the devices within.
Innovation Solution
Incorporating a high-rigidity member between the outer case wall and the energy storage device, which is mounted on the case wall, enhances the rigidity of the outer case and provides additional protection against external forces, while also ensuring insulation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If partitions are added to the outer case to prevent irregular deformation, then the overall structural stability is improved, but the protection against concentrated external forces applied to specific surfaces is insufficient
Solution Approach 1:
The patent applies local quality by adding reinforcement members specifically at critical locations where concentrated forces may be applied, rather than uniformly strengthening the entire outer case. The reinforcement members are strategically positioned at surfaces that face potential impact directions, providing localized enhanced protection while maintaining overall structural efficiency.
Solution Approach 2:
The patent employs composite material structure by combining the base outer case material with additional reinforcement members made of high-strength materials. This composite approach allows the outer case to maintain its original properties while gaining enhanced resistance to concentrated forces through the integrated reinforcement elements.
2Strength
If the outer case is made thicker to increase rigidity, then the protection against external forces is improved, but the weight and volume of the energy storage apparatus increase
Solution Approach 1:
The patent segments the strengthening function by separating the outer case from the reinforcement members. Instead of making the entire outer case thicker, the protection function is divided between the base case structure and discrete reinforcement elements, achieving the required strength with minimal additional weight.
Solution Approach 2:
The patent uses thin reinforcement members that provide maximum protection with minimal material consumption. These reinforcement elements are designed to be as thin as possible while maintaining effectiveness, reducing the overall weight and volume addition to the energy storage apparatus.
3Object-affected harmful factors
If reinforcement members are added to protect against concentrated forces, then the protection capability is improved, but the device complexity increases
Solution Approach 1:
The reinforcement members are designed to serve multiple functions: they provide mechanical strength against concentrated forces, maintain the structural integrity of the outer case, and can be integrated with the partition structure. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the reinforcement members with the existing outer case structure and partition system. By integrating these protective elements into the existing design framework rather than adding completely separate systems, the increase in structural complexity is minimized while achieving the desired protection capability.

AI summary
An energy storage apparatus includes an energy storage device and an outer case. The outer case includes a side wall portion disposed in an opposedly facing manner with a side surface of the energy storage device and a high rigidity member having higher rigidity than the side wall portion, the high rigidity member being disposed between the side wall portion and the energy storage device and mounted on the side wall portion.
