Container-Integrated Pyrotechnic Fire Extinguisher for Automated Warehouses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishing systems, such as sprinkler systems, are unsuitable for modern fulfillment centers and inventory systems due to potential damage to automated equipment and products, and manual extinguishers are ineffective in reaching all areas, especially in automated environments where fires may occur.
Innovation Solution
A disc-shaped fire extinguishing device is integrated into containers, equipped with a pyrotechnic material and a detonator, activated by a temperature sensor and RFID chip, releasing a fire extinguishing material like expansive foam to effectively extinguish fires within the immediate area without causing damage to surrounding equipment or products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sprinkler systems are used, then fire extinguishment coverage is improved, but damage to automated equipment and products increases
Solution Approach 1:
The fire protection system is segmented into individual container-level units rather than a centralized sprinkler system. Each container has its own fire extinguishing device that operates independently, allowing localized fire suppression without exposing the entire facility to water damage from conventional sprinklers.
Solution Approach 2:
The fire extinguishing system transitions from uniform global coverage (sprinklers throughout the facility) to localized targeted suppression. Each container is equipped with its own fire extinguishing device that releases extinguishing material only within that specific container, providing local quality protection that prevents collateral damage to equipment and products in adjacent areas.
2Device complexity
If manual fire extinguishers are used, then equipment complexity is reduced, but accessibility to all areas decreases
Solution Approach 1:
The fire extinguishing system operates autonomously without requiring human intervention. Temperature sensors automatically detect fire conditions and trigger the fire extinguishing device to release extinguishing material. This self-service capability ensures that fires in inaccessible areas of automated environments can be detected and suppressed without human presence or manual operation.
Solution Approach 2:
The manual mechanical operation of traditional fire extinguishers is replaced with an automated sensor-based system. Temperature sensors and control logic substitute for human decision-making and manual activation, enabling the system to respond to fires in locations that would be inaccessible or dangerous for human operators.
3Object-affected harmful factors
If targeted fire suppression is implemented, then damage to surrounding equipment is minimized, but device complexity increases
Solution Approach 1:
The fire extinguishing device is nested within each container structure, utilizing the container itself as the deployment location. This nesting approach integrates the fire protection function into the existing container design without requiring separate complex installation infrastructure, thereby minimizing damage risk while managing device complexity through clever spatial integration.

AI summary
Techniques and safety devices are described for extinguishing fires within an inventory management system. A plurality of fire extinguishing devices for a plurality of containers in an inventory management system is monitored. Upon determining that a fire condition is occurring within the inventory management system, a positional information data store is queried to determine a current position of a first container within the inventory management system. Two or more containers within the inventory management system that are in close proximity to the first container are identified and one or more wireless signals are transmitted to two or more fire extinguishing devices of the plurality of fire extinguishing devices that are contained within the two or more containers, to activate the two or more first extinguishing devices. The plurality of containers is scanned using an infrared scanning device to determine whether all fire conditions within the inventory management system are extinguished.
