Modular Wall Arrangement for Containing Vehicle Fire Extinguishing Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for extinguishing electric vehicle fires in confined spaces, such as underground garages, are inadequate as they either require complex constructions that are difficult to transport or fail to contain the extinguishing agent effectively, leading to uncontrolled spreading and safety risks.
Innovation Solution
A modular, adjustable wall arrangement that can be erected around a vehicle to enclose it laterally, using a combination of modules with floor profiles and adjustable devices like linear drives or pneumatic cylinders to surround and flood the vehicle with extinguishing agents, preventing uncontrolled agent spread and minimizing disruption to the parking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a container is used to store the vehicle with extinguishing agent for 48 hours, then the fire can be extinguished completely, but the construction becomes complex and difficult to transport
Solution Approach 1:
The extinguishing system is divided into separate functional modules: a movable wall arrangement that can be assembled around the vehicle and a separate extinguishing agent storage container. This segmentation allows the wall arrangement to be simple and transportable while the container provides reliable fire extinguishing capability through controlled containment of the extinguishing agent.
Solution Approach 2:
The movable wall arrangement acts as an intermediary structure between the extinguishing agent container and the vehicle. It creates a controlled environment that directs the extinguishing agent onto the vehicle without requiring the vehicle itself to be stored in a complex container for 48 hours, thus simplifying the overall construction while maintaining fire extinguishing effectiveness.
2Reliability
If emergency services intervene in battery fire, then the fire can be extinguished, but the high temperature endangers the building fabric and leads to structural weaknesses
Solution Approach 1:
The extinguishing agent is contained and directed locally onto the vehicle through the movable wall arrangement, creating a focused extinguishing zone. This local application prevents the uncontrolled spreading of extinguishing agent and concentrates the cooling effect on the vehicle, thereby reducing the overall temperature impact on the surrounding building fabric and structure.
Solution Approach 2:
The high temperature from the battery fire, which normally endangers the building, is converted into a beneficial effect by using it to trigger the extinguishing system. The heat activates the wall arrangement and extinguishing agent delivery, transforming the harmful thermal energy into the activation mechanism for safe fire extinguishing.
3Temperature
If the extinguishing agent is not restrained from spreading, then the fire can be cooled, but the agent spreads uncontrolled and creates safety risks
Solution Approach 1:
The movable wall arrangement creates a localized containment zone that directs the extinguishing agent precisely where it is needed - onto the vehicle. This local confinement ensures the agent provides effective cooling on the vehicle while preventing uncontrolled spreading to other areas, thereby eliminating the safety risks associated with uncontrolled agent distribution.
4Reliability
If a fixed wall arrangement is used to enclose the vehicle, then the extinguishing agent is contained effectively, but the parking space is blocked and access is restricted
Solution Approach 1:
The wall arrangement is designed to be movable rather than fixed, allowing it to be positioned around the vehicle when needed and removed or repositioned when not needed. This dynamic configuration enables effective containment of the extinguishing agent during fire emergency operations while maintaining ease of operation and access to the parking space during normal use, resolving the contradiction between containment reliability and operational flexibility.
