Hazardous Material Container With Integrated Fire Suppressant Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for holding flammable dangerous goods, such as damaged vehicles, face challenges in effectively combating fires within the container while preventing environmental contamination from pollutants and ensuring safe handling and transportation of the extinguishing agent.
Innovation Solution
The container integrates an extinguishing agent tank with a self-sufficient supply system, including fluid lines and a pump for introducing and removing the extinguishing agent, which allows for targeted and efficient fire suppression and agent recycling, reducing the need for external supplies and minimizing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external extinguishing agent supply system is used, then the container can be equipped with fire suppression capability, but the system requires external connections and supply hoses which increases device complexity and reduces operational efficiency
Solution Approach 1:
The container is equipped with an integrated extinguishing agent tank and pump system that enables autonomous fire suppression operations. The system draws extinguishing agent from its own onboard tank through fluid lines and pumps, eliminating the need for external supply connections and hoses, thereby reducing device complexity while maintaining reliable fire suppression capability
Solution Approach 2:
The extinguishing agent storage tank is merged with the container structure itself, integrating the fire suppression system into the container's overall design. This combination eliminates separate external supply equipment and connections, simplifying the system while ensuring dependable fire suppression functionality
2Reliability
If the container uses conventional external extinguishing agent supply, then fire suppression is possible, but the extinguishing agent must be manually supplied and removed which reduces productivity and increases loss of time
Solution Approach 1:
The integrated pump system automatically draws extinguishing agent from the onboard tank and delivers it to the fire location, then automatically drains the spent agent back to the tank or external containment. This automated cycle eliminates manual intervention for both supply and removal operations, significantly improving productivity and operational efficiency while maintaining effective fire suppression
Solution Approach 2:
The pump system enables continuous circulation of extinguishing agent through the container interior, maintaining constant fire suppression capability. The automated drain function ensures continuous operation by readily removing spent agent, eliminating downtime associated with manual agent replacement and enhancing overall productivity
3Ease of operation
If the container allows extinguishing agent to be drained externally, then the agent can be removed for transport, but this creates risk of environmental contamination from pollutants and chemical components
Solution Approach 1:
A sealed fluid line system with integrated shut-off devices acts as an intermediary between the container interior and external environment during agent drainage. This controlled intermediary pathway allows safe removal of extinguishing agent while preventing escape of contaminated substances, thus enabling ease of operation without environmental contamination
Solution Approach 2:
The container maintains a sealed environment during fire suppression operations, and the controlled drainage system ensures that the atmosphere inside remains contained. This prevents pollutants and chemical components from escaping into the environment while still allowing agent removal through controlled pathways with proper shut-off capabilities
4Adaptability or versatility
If the container is equipped with integrated extinguishing agent tank and pump system, then the system becomes self-sufficient, but this increases the volume and weight of the container
Solution Approach 1:
The integrated tank and pump system serves multiple functions: storing extinguishing agent, pumping it to fire locations, and draining spent agent. This multi-functionality consolidates what would otherwise require separate equipment, achieving self-sufficiency without proportionally increasing container volume, as the same components perform multiple operational roles
