Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oceanic flooding with large amount of extinguishing water is used, then fire extinction capability is improved, but transport effort and logistics complexity increase significantly
Solution Approach 1:
The patent divides the extinguishing system into multiple segments: integrated water tanks within the container, aerosol extinguishing devices for immediate response, and spray nozzles for distributed water application. This segmentation eliminates the need for single large-volume water transport while maintaining effective fire suppression capability.
Solution Approach 2:
The container is pre-equipped with integrated water tanks and aerosol extinguishing devices before transport. This preliminary preparation ensures that fire suppression resources are immediately available upon detection of thermal runaway, eliminating the need for external water supply and rapid large-scale water transport.
2Reliability
If real-time monitoring and integrated extinguishing systems are implemented, then fire detection and response capability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into the container structure: monitoring devices detect thermal conditions, integrated water tanks provide water supply, aerosol generators deliver extinguishing agent, and spray nozzles distribute water. This integration reduces overall system complexity compared to separate external systems while improving response capability.
Solution Approach 2:
The container is designed as a self-sufficient system with built-in monitoring and extinguishing capabilities. The system automatically detects thermal runaway conditions and activates appropriate suppression mechanisms without requiring external fire brigade intervention or complex external infrastructure.
3Reliability
If container is designed for fire-critical cargo, then safety performance is improved, but loss of useful action increases due to total loss of flooded e-vehicles
Solution Approach 1:
The system applies partial flooding through targeted spray nozzles rather than complete oceanic flooding. Aerosol devices provide concentrated extinguishing action at the fire source, while spray nozzles apply water locally to cooling channels. This partial application suppresses fire effectively while minimizing water consumption and vehicle damage.
Solution Approach 2:
The patent changes the physical parameters of water application: using high-pressure spray nozzles for targeted cooling, controlling water flow rates to match fire intensity, and adjusting aerosol discharge parameters for optimal extinguishing effect. These parameter optimizations achieve fire suppression with minimal water, preserving vehicle usability when possible.

AI summary
The invention relates to a transport or storage container with a sealable receiving compartment (2) for the transport and/or temporary storage, in particular for quarantine storage, of flammable cargo, especially high-voltage batteries and/or at least one electric vehicle (3) with high-voltage batteries. According to the invention, the container, as a safety transport container (1), has several monitoring devices for detecting a fire-critical condition, in particular overheating and/or an open fire and/or a short circuit, of the cargo in real time during the entire transport and, if applicable, storage period.According to the invention, the monitoring device has a reporting system that correlates the measurement data and, upon detection of a critical change in the condition of the cargo, reports faults in real time or can automatically trigger the activation of fire delay and/or fire extinguishing devices integrated into the container using cooling and extinguishing agents. Furthermore, the container has an integrated coolant spray system with integrated tank systems that enables autonomous cooling or extinguishing operations and, after active use, can retain coolant for reuse or filter or decontamination for controlled disposal.
