Battery Rack Flow-Guiding Structure for Downstream Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing fire-extinguishing and charging lockers, the fire extinguishing agent tube can melt due to ignition, leading to insufficient supply of the extinguishing agent to downstream areas.
Innovation Solution
A battery placement rack with support portions and lateral guide plates is designed to direct the flow of fire extinguishing agent laterally, ensuring it reaches all battery units even if the agent tube melts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fire extinguishing agent tube is used to supply all storage boxes, then the device complexity is reduced, but the reliability of fire extinguishing agent supply deteriorates when the tube melts due to ignition
Solution Approach 1:
The fire extinguishing system is segmented into multiple independent supply paths. Each storage box has its own fire extinguishing agent supply tube connected to the supply tank, creating parallel independent channels. This segmentation ensures that if one tube melts due to ignition, other tubes remain intact and can still supply fire extinguishing agent to their respective storage boxes, thereby maintaining system reliability while managing complexity through modular design
2Area of stationary object
If the fire extinguishing agent tube is routed through all storage boxes, then comprehensive coverage is achieved, but the risk of insufficient supply to downstream areas increases when melting occurs
Solution Approach 1:
The single routed tube system is divided into multiple separate tubes, each serving specific storage boxes. This segmentation creates independent supply paths that prevent downstream supply failure when upstream melting occurs
Solution Approach 2:
The supply system transitions from a single linear dimensional path (one tube through all boxes) to a multi-dimensional network (multiple tubes branching to different boxes). This dimensional change provides redundant pathways, ensuring that if one path is blocked by melting, fire extinguishing agent can still reach all areas through alternative paths

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses the insufficient supply of fire extinguishing agent to downstream areas, ensuring that all battery units receive adequate protection in case of a fire.
Implementation Method 1
lateral guide plates disposed downward from the support portions, for guiding a flow of a fire extinguishing agent in a lateral direction
Implementation Method 2
an opening that is opened on a side of the placement portion to cause the fire extinguishing agent to flow down

AI summary
The battery placement rack includes a plurality of support portions arranged so as to be spaced apart from each other in the up-down direction, and a plurality of lateral guide plates arranged below each support portion and laterally guiding the flow of the fire extinguishing agent. Each of the support portions includes a placement portion on which the battery unit can be mounted, and an opening formed on a side of the placement portion to allow the fire extinguishing agent to flow down. The lateral guide plate has an edge portion that causes the fire extinguishing agent flowing down through the opening in the support portion located above the lateral guide plate to flow down toward the placement portion in the support portion located below the lateral guide plate.
