Solution Overview

Problem

Commercial aircraft stowage bins are prone to germ contamination and difficult to operate, and passengers can inadvertently open them during restricted flight periods, posing safety hazards.

Innovation Solution

A wireless stowage bin control system that allows flight personnel to remotely open and close bins without physical contact using sensors and electronic latches, preventing passengers from accessing them during takeoff, landing, and turbulence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a physical latch is used for stowage bin operation, then the bin can be opened and closed, but the latch becomes contaminated with germs and bacteria and is difficult to operate for some individuals

Engineering Contradiction:
Improvestowage bin operationVSAvoidgerm contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical latch system with an electronic latch controlled by a motor. The electronic latch can be actuated remotely via wireless communication, eliminating the need for physical contact with the latch mechanism. This substitution resolves the contradiction by maintaining bin operation capability while eliminating germ contamination and improving ease of operation for all individuals.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a master control device as an intermediary between the user and the stowage bin latch. This control device communicates wirelessly with the bin's electronic latch, allowing users to open and close bins without physically touching the latch. The intermediary eliminates direct contact with potentially contaminated surfaces while maintaining full operational control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If passengers can freely access stowage bins, then they can store and retrieve items, but bins may be opened during restricted flight periods creating safety hazards

Engineering Contradiction:
Improvebin access controlVSAvoidsafety during flight
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a dynamic control system where the master control device can adjust latch accessibility based on flight conditions. During restricted periods (takeoff, landing, turbulence), the system automatically locks bins and prevents passenger access. During normal periods, bins remain accessible. This dynamic adaptation resolves the contradiction by providing both safety during critical phases and versatility for passenger use during normal operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where the master control device receives information about flight conditions and automatically adjusts bin accessibility accordingly. The system monitors flight phase data and responds by enabling or disabling latch operation, ensuring bins remain closed during restricted periods while allowing access during normal flight, thus maintaining both safety and adaptability.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If a wireless control system is implemented, then bin operation is simplified and hygiene improved, but system complexity increases

Engineering Contradiction:
Improvebin control operationVSAvoidcontrol system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The master control device serves multiple functions: it controls multiple stowage bins simultaneously, manages electronic latches, provides user interfaces for operation, and integrates with flight management systems. By consolidating these functions into a single universal device, the system achieves simplified operation and improved hygiene without proportionally increasing overall system complexity.

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

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.
