Safe storage box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safe storage boxes fail to quickly suppress fires occurring inside the storage box, particularly with lithium-ion batteries, which are highly reactive and pose a risk of explosion.
Innovation Solution
A safe storage box design that includes a fire extinguishing agent supply unit with a fire-detection sensor, control unit, and nozzles to immerse storage objects in a fire extinguishing agent when a fire occurs, using a NaCl aqueous solution for secondary batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional safe storage boxes are used to protect storage objects from external fires, then protection from external fires is improved, but the ability to quickly suppress internal fires deteriorates
Solution Approach 1:
The patent pre-installs fire extinguishing agent tanks within the storage box and positions nozzles at strategic locations. When a fire is detected by sensors, the system immediately activates the pre-positioned extinguishing agents through the nozzles, enabling rapid response to internal fires without requiring external intervention or assembly.
Solution Approach 2:
The patent introduces fire extinguishing agents as an intermediary substance between the fire source and the storage objects. These agents act as a mediating element that intercepts and suppresses the fire propagation, preventing direct contact between flames and stored materials while maintaining the protective enclosure structure.
2Productivity
If fire extinguishing agents are sprayed to extinguish fires, then fire suppression speed is improved, but damage to unaffected items deteriorates
Solution Approach 1:
The patent divides the storage box into multiple compartments with individual nozzles positioned in each section. When fire is detected in a specific compartment, only the nozzles in that compartment activate to spray extinguishing agents locally. This segmented approach confines the extinguishing action to the affected area, preventing unnecessary exposure of unaffected items to chemicals while maintaining rapid suppression capability.
Solution Approach 2:
The patent implements localized fire suppression by positioning nozzles to target specific compartments or zones within the storage box. The fire extinguishing agents are applied with local quality - concentrated precisely where the fire occurs rather than uniformly throughout the entire storage space. This localized application minimizes chemical exposure to unaffected items while ensuring effective fire suppression at the source.
Applied Scientific Principles
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 design effectively extinguishes fires by immersing storage objects in the fire extinguishing agent, preventing further discharge and explosion, while minimizing damage to unaffected items.
Implementation Method 1
a fire-detection sensor disposed in the housing to detect a fire occurring in the storage objects
Implementation Method 2
supply a fire extinguishing agent into the shelf so that the storage objects are immersed in the fire extinguishing agent
