Battery Module Support Frame Layout for Compact Energy Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage devices face challenges in reducing installation area and ensuring structural rigidity, particularly when battery modules are installed horizontally, leading to increased thickness and space requirements.
Innovation Solution
The energy storage device incorporates a support frame with lower and upper support members, vertical support members, and a case design with larger side portions to accommodate battery modules, utilizing polycarbonate sheets and a top fixing member to stabilize the structure while minimizing installation area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If battery modules are installed horizontally with wide bottom face downward, then the stability of battery module installation is improved, but the thickness of outer box is increased and the installation area is increased
Solution Approach 1:
The patent changes the installation orientation of battery modules from horizontal to vertical arrangement. By stacking battery modules vertically on upper and lower support members instead of placing them horizontally, the thickness of the outer box is reduced while maintaining installation stability through the support frame structure.
2Stability of the object's composition
If battery modules are installed horizontally with wide bottom face downward, then the stability of battery module installation is improved, but the installation area is increased
Solution Approach 1:
The patent transitions from horizontal to vertical installation of battery modules. This dimensional change allows the battery modules to be stacked in the vertical direction rather than spreading out horizontally, thereby reducing the installation area while maintaining stability through the support frame with upper and lower support members.
3Strength
If support frame with upper and lower support members is used, then the rigidity of structure is improved, but the device complexity is increased
Solution Approach 1:
The support frame is segmented into upper and lower support members that independently support battery modules at different heights. This segmentation provides structural rigidity through the distributed support system while keeping each individual support member relatively simple in design, balancing strength requirements with manufacturing simplicity.
