Aircraft Crew Rest Monument with Overhead Galley Cart Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crew rest systems in aircraft compromise on space for passenger seats due to their large footprint to accommodate increased cart storage capacity, particularly in the 80-inch overhead flight crew rest areas.
Innovation Solution
A compact crew rest system with a monument that houses four full-sized galley carts in a forward-facing compartment, integrated with an overhead bunk module and a forward rest area, optimizing space usage by extending the length by only 3 inches over a baseline design, allowing for additional cart storage and passenger seating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the crew rest area is enlarged to house four galley carts (80-inch version), then cart storage capability is improved, but the footprint increases reducing space for passenger seats
Solution Approach 1:
The patent transitions from horizontal expansion to vertical utilization by positioning the crew rest area overhead. The monument structure extends vertically from the ceiling, with galley carts stored in compartments above the passenger cabin level. This dimensional shift allows four full-sized galley carts to be accommodated without increasing the horizontal footprint, as the storage volume is accessed via vertical stairs rather than lateral expansion.
2Area of stationary object
If the crew rest area is compacted to reduce footprint, then space for passenger seats is improved, but cart storage capability is reduced
Solution Approach 1:
The patent implements nesting by placing the crew rest area within the existing overhead structure. The monument is integrated into the ceiling framework, with galley cart compartments nested within the vertical space above passenger seats. The access stairs are nested within the monument structure itself, allowing multiple functional elements (storage compartments, access pathways, structural support) to occupy overlapping spatial volumes without conflicting horizontally.
3Area of stationary object
If the monument width is reduced to 53 inches for compactness, then footprint is improved, but access and storage efficiency may be worsened
Solution Approach 1:
The patent incorporates dynamic elements within the constrained 53-inch width, including movable doors with sufficient clearance for crew members, and a stair design that provides adequate stepping surface area. The internal passage width is optimized to allow smooth cart retrieval operations despite the external compact dimensions. The monument structure maintains structural integrity while accommodating operational requirements through carefully calibrated internal clearances and movable components.

AI summary
A crew rest system for an internal cabin of a vehicle, such as a commercial aircraft, includes a monument having a cart compartment configured to retain three or more galley carts. An access area having an entrance is on a side of the monument. The entrance leads into an internal passage having steps.
