Solution Overview

Problem

Existing aircraft fire detection systems rely heavily on manual crew intervention for assessing and responding to fire alarms, lacking integration with other onboard systems to provide automated support and accurate remedial actions.

Innovation Solution

A holistic fire detection system integrating fire detectors, monitoring systems, cargo tracking, aircraft control, and display devices to provide automated assessment and recommended remedial procedures to cockpit crews.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual crew intervention is used for assessing and responding to fire alarms, then the system can provide basic fire detection, but the response time is delayed and the crew workload is increased

Engineering Contradiction:
Improvefire detection reliabilityVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs self-assessment by automatically evaluating fire alarm signals against pre-stored cargo information and remedial procedures, eliminating the need for manual crew assessment and enabling immediate automated response generation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Cargo information and remedial procedures are pre-stored in the system before any fire event occurs, allowing the system to immediately retrieve and process relevant data when a fire alarm is triggered, rather than requiring crew members to manually gather this information during an emergency

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If manual crew intervention is used for assessing and responding to fire alarms, then the system structure can be simpler, but the crew workload and complexity of manual checks are increased

Engineering Contradiction:
Improvesystem structure complexityVSAvoidcrew operation ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system automatically retrieves cargo information, assesses fire alarms, and generates remedial procedures without requiring crew members to manually check manuals or gather information, thereby reducing operational complexity for the crew despite increased system automation

Inventive Principle:
Principle #25Self-service

3Productivity

If automated data integration and decision support are provided to the crew, then the response efficiency is enhanced, but the system complexity is increased

Engineering Contradiction:
Improveresponse efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system integrates multiple functions including cargo information management, fire alarm assessment, remedial procedure generation, and navigation recommendation into a single unified platform, improving response efficiency while managing complexity through functional integration rather than separate systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system acts as an intermediary between various aircraft systems (cargo management, fire detection, navigation) and the crew, automatically integrating data from multiple sources and presenting coordinated remedial procedures, thereby enhancing response efficiency while shielding the crew from underlying system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A fire detection system for monitoring an aircraft compartment and supporting a cockpit crew with taking remedial action in case of a fire alarm comprises a fire detector installed within the aircraft compartment and configured to provide fire warning data on a potential fire within the aircraft compartment; a monitoring system installed within the aircraft compartment and configured to provide live monitoring data on cargo stored in a monitored area of the aircraft compartment; a cargo tracking system configured to provide cargo data of the cargo stored in the monitored area comprising at least one of cargo identification data, cargo type data and cargo status data; an aircraft control system configured to provide aircraft status data comprising at least one of environmental data, fuel status data, navigation data, passenger data and crew data; a system control configured to assess the fire warning data, the cargo data and the aircraft status data and to provide a recommended remedial procedure based on the assessment in case the fire detector raises a fire alarm at least in an affected portion of the monitored area of the aircraft compartment; and a display device configured to display the live monitoring data and the recommended remedial procedure to the cockpit crew in case of a fire alarm.
