Aircraft Cabin Sensor Network for Automated Safety Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cabin attendants face time-consuming manual checks during pre-flight and landing procedures to ensure tray tables are stowed, stowage bins are closed, and passengers are seated, which can be inefficient and labor-intensive.
Innovation Solution
A crew information system with weight detection devices and sensors integrated into seat cushions, overhead compartments, and tray tables, providing real-time data on passenger and object presence, weight, and location, alerting crew to compliance issues and facilitating automated safety checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual checks are conducted by cabin attendants to verify tray tables, stowage bins, and passenger seating, then safety compliance is ensured, but time and labor are significantly consumed
Solution Approach 1:
The system enables automatic self-monitoring of safety compliance parameters. Sensors integrated into tray tables, stowage bins, and seats automatically detect and report their status without requiring manual inspection by cabin attendants, thus eliminating the time-consuming manual checks while maintaining safety compliance
Solution Approach 2:
The patent replaces the mechanical manual inspection process with an automated electronic sensing and reporting system. Weight sensors, position sensors, and control circuits automatically detect and communicate the status of various cabin elements, substituting the physical manual checking process with an electronic automation system
2Reliability
If manual inspections are performed to verify weight distribution in stowage compartments, then load balance is ensured, but the process is labor-intensive and time-consuming
Solution Approach 1:
Weight sensors integrated into stowage compartments automatically measure and report the weight of stored objects, enabling self-monitoring of load distribution. This eliminates the need for manual weight verification while ensuring proper load balance compliance
Solution Approach 2:
The manual weight verification process is replaced with electronic weight sensors that automatically detect and communicate load information. This substitution transforms the labor-intensive manual inspection into an automated electronic measurement and reporting system
3Reliability
If visual inspections are conducted to ensure passengers remain seated during TTOL, then safety compliance is maintained, but the process requires significant crew time and effort
Solution Approach 1:
Weight sensors integrated into seats automatically detect whether a passenger is seated by sensing their weight. The system self-monitors seating compliance and communicates status to the crew, eliminating the need for manual visual inspections and reducing crew workload while maintaining safety compliance

AI summary
In an illustrative embodiment, a crew information system is coupled to sensors in passenger seats, seatbelts, tray tables and overhead bins. If the vehicle seat sensor subsystem senses a passenger on a seat and senses the corresponding passenger seat belt is unbuckled, the vehicle seat sensor subsystem may alert the flight crew of a non-compliance condition. The crew information system may also, for example, facilitate preparation for take-off by signaling the crew when, for all seats in which passengers are detected, all tray tables are stowed and all seatbelts are buckled. The crew may be similarly informed of overhead bins which are not properly latched. Crew member notifications may advantageously report the specific nonconforming issue and seat or bin position.
