Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft fire protection systems are inadequate in effectively suppressing uncontrolled combustion reactions within segregated spaces of an aircraft, posing a risk to passengers, cargo, and engine housings.
Innovation Solution
The enhanced aircraft fire protection system comprises a mechanical fire suppression structure that mounts within the aircraft structure, providing fire suppression protection for segregated spaces by removing oxygen through a pressure differential mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing aircraft fire protection systems are used, then the system structure is simple, but the fire suppression effectiveness is inadequate
Solution Approach 1:
The aircraft is divided into multiple segregated spaces (cargo compartments, passenger compartments, engine housings, landing gear housings), each equipped with its own fire suppression instantiation. This segmentation allows targeted fire suppression in specific areas without requiring a complex system to protect the entire aircraft uniformly, thus improving fire suppression effectiveness while managing system complexity.
Solution Approach 2:
A pressure differential mechanism acts as an intermediary to deliver fire suppressant agents into segregated spaces. The system uses pressure differentials to overcome ventilation systems that may be drawing air into fire zones, ensuring effective delivery of suppressant agents without requiring overly complex delivery mechanisms.
2Object-affected harmful factors
If ventilation systems operate continuously, then air circulation is maintained, but oxygen supply to fire zones increases combustion intensity
Solution Approach 1:
The fire suppression system anticipates the harmful effect of ventilation systems drawing oxygen into fire zones by pre-positioning suppressant agents and using pressure differentials to counteract the ventilation effect. The system applies counter-pressure to prevent oxygen-rich air from being drawn into fire zones, thereby reducing combustion intensity while allowing ventilation systems to continue operating.
3Reliability
If fire suppressant agents are delivered without pressure differential, then the delivery system is simple, but ventilation systems draw air into fire zones increasing combustion
Solution Approach 1:
A pressure differential mechanism serves as an intermediary to deliver fire suppressant agents into segregated spaces. This pressure differential overcomes the effect of ventilation systems that draw air into fire zones, ensuring effective suppressant delivery without requiring overly complex delivery mechanisms.
Solution Approach 2:
The system uses pneumatic pressure differentials to deliver suppressant agents into fire zones. By utilizing pressure differentials between the delivery system and the segregated space, the system effectively pushes suppressant agents against the airflow created by ventilation systems, improving fire suppression effectiveness while keeping the delivery system relatively simple.
