Electronic stowage bin control systems and methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial aircraft stowage bins pose health risks due to frequent handling of germ-infested latches and safety hazards during turbulence, as passengers can inadvertently open bins during restricted periods.
Innovation Solution
A wireless stowage bin control system that allows for touch-free operation and remote control by flight personnel, using sensors and light-emitting elements to manage bin states and prevent passenger access during takeoff, landing, and turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passengers manually open stowage bins by touching the latch, then the bin can be opened, but germs and bacteria are transmitted and accessibility is reduced for certain individuals
Solution Approach 1:
The patent replaces the manual mechanical latch operation with an automated electronic locking mechanism. The latch is no longer manually manipulated but is instead controlled by a motorized actuator that locks and unlocks the bin based on signals from the master control device, eliminating the need for physical contact with the latch.
Solution Approach 2:
The stowage bin system provides self-service through automatic locking and unlocking operations. The master control device automatically manages the latch state without requiring passenger intervention, and the bin can be opened automatically when needed, reducing repetitive manual tasks for crew while maintaining accessibility.
2Ease of operation
If passengers can freely open stowage bins, then accessibility is maintained, but safety hazards occur during turbulence and restricted periods
Solution Approach 1:
The locking mechanism transitions from a static manual latch to a dynamic electronically controlled system. The master control device can change the latch state (locked/unlocked) based on flight conditions, automatically preventing access during turbulence and restricted periods while allowing access during normal operations.
Solution Approach 2:
The system incorporates feedback control where the master control device receives information about flight conditions and automatically adjusts the latch state accordingly. The system monitors and responds to operational requirements, automatically locking bins during restricted periods and unlocking them when safe.
3Productivity
If flight attendants manually control each stowage bin, then bin operation is possible, but repetitive tasks increase and operational efficiency decreases
Solution Approach 1:
The patent merges control of multiple stowage bins into a single master control device that can simultaneously or sequentially operate multiple bins. This consolidation eliminates the need for flight attendants to manually control each bin individually, reducing repetitive tasks while the automated system manages the increased complexity of coordinating multiple bins.
Solution Approach 2:
The master control device serves multiple functions: it controls the locking mechanism, manages bin opening/closing operations, provides user interface for passenger requests, and coordinates with flight safety systems. This multi-functional device consolidates what would otherwise require multiple separate control systems.

AI summary
A stowage bin control system and method for a vehicle includes at least one stowage bin assembly that are configured to be selectively moved between an open position and a closed position, and a master control device that is separate and distinct from the stowage bin assemblies. The master control device is communicatively coupled to the stowage bin assemblies and is configured to operate the stowage bin assemblies.
