Solution Overview

Problem

Aircraft galleys have limited storage space and are typically fixed structures that cannot be easily adapted or reconfigured during flight, requiring tools for changes, which hinders efficient use of stowage space for different purposes.

Innovation Solution

An insertable galley unit with a rotatable shelf and retractable latch system that allows the shelf to be adjusted between stowed and deployed positions without tools, using a piano hinge for stability and minimal space usage, and retractable latches for secure engagement with the side wall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the galley structure is made fixed and stable, then structural reliability is improved, but adaptability for different purposes during flight deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidreconfigurability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The shelf is designed to be dynamically reconfigurable between stowed and deployed positions using a hinge mechanism, allowing the galley structure to adapt to different purposes during flight while maintaining structural stability when locked in position

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the shelf is made retractable and reconfigurable, then adaptability is improved, but device complexity deteriorates

Engineering Contradiction:
ImprovereconfigurabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shelf assembly is segmented into modular components (shelf panel, hinge mechanism, latch system) that can independently function, allowing for easier maintenance and reduced overall system complexity while maintaining reconfigurability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retractable shelf incorporates self-latching mechanisms that automatically secure the shelf in deployed or stowed positions without requiring additional fastening operations, reducing operational complexity

Inventive Principle:
Principle #25Self-service

3Strength

If the shelf uses a piano hinge for stability, then structural strength is improved, but space requirement deteriorates

Engineering Contradiction:
Improveshelf stabilityVSAvoidspace occupation
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The piano hinge is positioned along the longitudinal edge of the shelf rather than the broad face, utilizing the thin dimensional profile of the shelf to accommodate the hinge mechanism without significantly increasing overall space requirements

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