Modular Cabinet Wall Assembly for Thermal Runaway Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy storage cabinets using metal containers are prone to fire accidents due to thermal runaway of batteries during storage or transportation, as the separator can be damaged, leading to short circuits and high-temperature chemical reactions, which can ignite combustible materials and cause damage to adjacent devices.
Innovation Solution
A cabinet unit and system design featuring extruded side walls with fitting pieces that snap fit together, forming a secure and airtight interface, and incorporating a concrete body with synthetic fibers for high compressive and bending strength, along with a flame-resistant material layer to contain and manage high temperatures, preventing fire propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple individual components are assembled for energy storage cabinets, then loading and transportation convenience are improved, but assembly complexity increases
Solution Approach 1:
The cabinet is designed as modular components (side walls, top plate, bottom plate, doors) that can be independently manufactured and assembled. This segmentation enables convenient loading and transportation while maintaining manageable assembly complexity through standardized connection interfaces.
Solution Approach 2:
Standardized fitting pieces and connection structures are designed to be universally applicable across different cabinet configurations. The same connection mechanisms are used for assembling side walls, top plates, bottom plates, and doors, reducing the need for specialized assembly procedures.
2Ease of manufacture
If side walls are constructed with multiple units, then manufacturing and assembly flexibility are improved, but connection reliability may deteriorate
Solution Approach 1:
Side walls are divided into multiple manufacturable units that can be produced separately and then assembled. This segmentation improves manufacturing flexibility by allowing each unit to be optimized for production while maintaining overall structural integrity through reliable connection designs.
Solution Approach 2:
Traditional mechanical fastening methods are replaced with extruded fitting pieces that provide integrated mechanical interlocking and sealing functions. The extrusion process creates precise, repeatable connection geometries that enhance connection reliability while maintaining manufacturing flexibility.
