Aft Rest Area Assembly With Egress Flow Director
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft aft sections are inefficiently configured, leading to cramped galley spaces, congestion, and restricted movement due to the proximity of lavatories and galley stations, which hinders flight attendants' work and passenger flow.
Innovation Solution
The aft rest area assembly includes separate galley stations on either side of a central lavatory section with an egress flow director that extends into an unused egress aisleway, allowing for a direct path to emergency exits and enabling the conversion of multiple lavatories into a single expanded lavatory, reducing congestion and improving space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single galley area is used for multiple flight attendants, then space utilization is improved, but the space becomes cramped and restrictive causing flight attendants to bump into one another
Solution Approach 1:
The single galley area is divided into multiple separate galley stations (first galley station and second galley station), each positioned on opposite outboard sides of the lavatory section. This segmentation allows multiple flight attendants to work simultaneously in separate spaces, eliminating the crowding and interference problems while maintaining efficient use of the overall aft section area.
2Area of stationary object
If attendant seats are positioned proximate to lavatories, then space utilization is improved, but the seats interfere with lavatory door operation and passenger access
Solution Approach 1:
The attendant seats are positioned in specific locations within the aft rest area assembly that are proximate to the lavatories but carefully spaced to maintain adequate clearance. This local positioning ensures that when flight attendants are seated, there remains sufficient space for lavatory doors to open and for passengers to enter and exit the lavatories without interference, thus maintaining both space efficiency and operational ease.
3Area of stationary object
If lavatories and galley stations are positioned close together, then space utilization is improved, but congestion and restricted movement occur in the aft section
Solution Approach 1:
The layout transitions from a linear arrangement to a distributed two-dimensional configuration where the lavatory section is positioned centrally with galley stations on opposite outboard sides. This dimensional reorganization creates multiple independent work areas and maintains adequate circulation space, allowing efficient passenger flow and attendant movement without congestion while still maximizing the use of available cabin space.

AI summary
An aft rest area assembly is positioned within an aft section of an internal cabin of an aircraft. The aft rest area assembly may include a lavatory section including at least one lavatory, a first galley station positioned on a first outboard side of the lavatory section, and a second galley station positioned on a second outboard side of the lavatory. The first outboard side is opposite from the second outboard side. The first galley station is separated from the second galley station by the lavatory section. The lavatory section may also include an egress flow director that forwardly extends into one or more egress paths of the internal cabin. The egress path(s) connect to at least one emergency exit door.
