Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for energy storage systems (ESS) that can be quickly manufactured and installed, with a movable structure and a connection method that allows for rapid expansion and reliable connection of energy storage devices to efficiently meet increasing power demands.
Innovation Solution
The energy storage device is designed to be modular and transportable, featuring a housing with battery modules, a mounting portion, and exposed connecting portions, including busbars and insulating members, which enable quick and stable electrical connections between devices, along with a cooling system for efficient temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If energy storage devices are modularized for quick installation and transport, then installation speed and mobility are improved, but connection reliability and electrical stability may worsen
Solution Approach 1:
The energy storage device is divided into modular units with standardized housing, mounting portions, and connecting portions. Each module can be independently manufactured, transported, and installed, then connected to form larger systems. This segmentation enables quick deployment while maintaining connection reliability through standardized interfaces.
Solution Approach 2:
The housing structure serves multiple functions: it protects internal components, provides mounting surfaces for battery modules, incorporates connecting portions for electrical connections, and includes lifting holes for transport. This multi-functionality reduces the number of separate components needed, simplifying installation while ensuring reliable connections through integrated design.
2Productivity
If connecting portions are exposed to the outside for quick connection, then connection speed is improved, but protection against environmental factors and safety may worsen
Solution Approach 1:
The housing provides localized protection for most internal components while leaving specific connecting portions exposed or accessible from the outside. This selective exposure allows quick electrical connections without compromising the environmental protection of sensitive battery modules and internal components through the enclosed housing structure.
