Solution Overview

Problem

Conventional overhead bins in aircraft are difficult to access due to their high height, posing challenges for passengers, especially those with mobility issues, in lifting and placing luggage.

Innovation Solution

An articulating storage bin assembly with a movable portion that can articulate downward and laterally for easier loading, coupled with a biasing member to assist in lifting and a spring and damper system for smooth movement, allowing the bin to be returned to a closed position for secure storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If conventional overhead bins are mounted at high height to maximize storage space, then storage capacity is improved, but accessibility and ease of operation deteriorate

Engineering Contradiction:
Improvestorage capacityVSAvoidaccessibility
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The overhead bin incorporates a movable articulating portion that can dynamically change position between a closed storage position and an open access position. This articulating mechanism allows the bin to adapt its configuration based on operational needs, providing easy access when opened and maximizing storage when closed, thus resolving the contradiction between storage capacity and accessibility.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If overhead bins are positioned high to optimize space utilization, then space efficiency is improved, but lifting effort and safety deteriorate

Engineering Contradiction:
Improvespace efficiencyVSAvoidlifting effort
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The overhead bin is divided into a fixed portion and a movable articulating portion. This segmentation allows the articulating portion to be independently manipulated, reducing the effective weight and distance that passengers must lift luggage during the loading process, thereby reducing lifting effort while maintaining overall space efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The articulating portion moves along an arc-shaped path that combines vertical and horizontal displacement. This dimensional change in movement trajectory allows luggage to be placed at a more accessible intermediate position during loading, reducing the vertical lifting distance and effort required compared to conventional fixed high-position bins.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If the overhead bin structure is simplified for ease of manufacture, then manufacturing cost is reduced, but safety and secure storage capability deteriorate

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsecure storage
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The articulating portion incorporates a return mechanism with biasing members that automatically returns the articulating portion to the closed storage position after use. This dynamic feature provides secure storage by ensuring the bin is reliably closed during flight, while the mechanism itself uses simple mechanical components that are easy to manufacture and maintain.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing members automatically return the articulating portion to the closed position without requiring manual intervention from passengers or crew. This self-service mechanism ensures secure storage is maintained while using simple, easily manufactured spring or elastic elements rather than complex motorized systems.

Inventive Principle:
Principle #25Self-service

AI summary

A storage bin assembly includes a fixed bin portion, an articulating bin portion, and an articulation system. The fixed bin portion is configured to be mounted to an aircraft, and has a cavity configured for storage of luggage. The articulating bin portion is coupled to the fixed bin portion, and includes a shelf configured for supporting luggage. The articulation system movably couples the articulating bin portion to the fixed bin portion. The articulating bin portion is movable from a first position in which the articulating bin portion is proximate to the fixed bin portion to a second position at which the articulating bin portion is separated from the fixed bin portion and lower than the fixed bin portion.
