Solution Overview
Problem
Existing technologies face challenges in early and reliable detection of fires in aircraft and initiating effective countermeasures to prevent fire spread.
Innovation Solution
The development of an extinguishing device with a base element, an extinguishing agent container, a triggering device, and a data transmission device, which can be easily fitted in various positions within an aircraft. The device includes a monitoring system to detect fire-related parameters and transmit warning signals to a control unit, allowing for precise localization of the fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extinguishing devices are installed in multiple positions throughout an aircraft, then fire detection coverage and reliability are improved, but the complexity of the system increases and localization becomes more difficult
Solution Approach 1:
The aircraft is divided into multiple zones with individual extinguishing devices installed in each zone (cabin, cargo hold, engine compartments). Each device operates independently with its own sensor and discharge mechanism, allowing localized fire suppression without requiring a complex centralized system.
Solution Approach 2:
A control unit serves as an intermediary between the distributed extinguishing devices and the central monitoring system. The control unit receives signals from multiple devices, processes the information, and coordinates the response, simplifying the overall system architecture while maintaining high reliability through redundant distributed sensors.
2Reliability
If extinguishing devices are installed in multiple positions throughout an aircraft, then fire detection coverage is improved, but locating the triggered device becomes more difficult
Solution Approach 1:
Each extinguishing device is equipped with an optical indicator (such as an LED) that changes color or illuminates to indicate the device's status and location. When a device is triggered, the indicator provides visual confirmation of the specific device's location, enabling rapid identification and response while maintaining comprehensive fire detection coverage throughout the aircraft.
Solution Approach 2:
The control unit receives feedback signals from each extinguishing device's sensor and immediately processes this information to determine which specific device has been triggered. The system provides real-time feedback about the location and status of each device, allowing operators to quickly identify the fire source among multiple distributed devices without manual inspection.
3Ease of operation
If standardized extinguishing devices are used, then ease of installation and deployment is improved, but adaptability to different specific positions and requirements may be reduced
Solution Approach 1:
The extinguishing devices are designed as standardized universal units that can be installed in multiple locations throughout the aircraft (cabin, cargo hold, engine compartments). Each device performs the same core function of fire detection and suppression, but the system as a whole adapts to different positions through the distributed network of identical devices, each optimized for its specific installation location's fire risks.
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 solution enables standardized, easily deployable extinguishing devices that can be triggered to release extinguishing agents, while also transmitting warning signals to a control unit, facilitating effective fire localization and countermeasures.
Implementation Method 1
the extinguishing agent is intended to displace the oxygen present in the surrounding area of the extinguishing device, so as to remove the basis for a fire occurring in the surrounding area
Implementation Method 2
In addition, the extinguishing agent may also have a cooling effect

AI summary
An extinguishing device for an electrical unit on an aircraft cabin monument or in an aircraft structure cavity, a combination of a holder and an extinguishing device and systems formed by extinguishing devices and a control unit and by combinations of an extinguishing device and a holder and a control unit. The extinguishing device has a base element for a holder. An extinguishing agent container has a casing and holds an extinguishing agent. A triggering device is connected to the extinguishing agent container to act in response to receiving a triggering signal wherein an extinguishing agent is released into the extinguishing device surrounding area. A data transmission device has a data store with an identifier unique to the extinguishing device and connected to the triggering device, the data transmission device for sending a warning signal via a network to a control unit in response to the triggering device receiving the triggering signal.
