Aircraft Monument with Pivotable Flight Attendant Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft passenger cabins face inefficiencies in space utilization, particularly in the door aisle region, which is often underutilized, and existing flight attendant seat designs do not optimize safety and visibility during emergencies.
Innovation Solution
An aircraft cabin design featuring a centrally located monument in the door aisle that incorporates flight attendant seats, storage compartments, and a vending machine, with seats pivotable to reduce space usage and ensure unobstructed views, and integrated safety belts and display screens for enhanced safety and passenger guidance during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight attendant seats are arranged in the door aisle region, then safety monitoring capability is improved, but space utilization deteriorates
Solution Approach 1:
The patent combines flight attendant seats with monument structures (toilets, galleys, or storage units) located in the door aisle region. By merging the seat function with the monument structure, the design achieves dual functionality: safety monitoring is maintained through proper seat positioning and visibility, while space utilization is improved by eliminating the need for separate dedicated seat areas. The monument structure serves both as a functional element (toilet/galley/storage) and as a mounting structure for the flight attendant seats.
2Area of stationary object
If additional passenger seats are installed in underutilized regions, then space utilization is improved, but safety and comfort deteriorate
Solution Approach 1:
The patent applies local quality by carefully selecting specific locations within the door aisle region for monument installation, ensuring that these locations do not compromise safety corridors, evacuation paths, or passenger comfort. The monuments are positioned in areas that are naturally underutilized, and the design ensures that monument dimensions and positioning maintain required safety clearances while maximizing space utilization in appropriate zones.
3Ease of operation
If flight attendant seats are made movable to improve passage space, then ease of operation is improved, but safety and stability deteriorate
Solution Approach 1:
The patent implements dynamics by designing flight attendant seats with movable or foldable components that can be adjusted between different positions. The seats can be folded flat against the monument structure when not in use, creating additional passage space, and can be positioned upright when needed for safety monitoring. The design incorporates appropriate mounting mechanisms and restraint systems to ensure that the movable seats maintain safety and stability when deployed, resolving the contradiction between ease of operation and reliability.

AI summary
An aircraft region (100) comprises a main aisle (101) extending along a longitudinal axis (L) of an aircraft cabin, a door aisle (102) extending along a transverse axis (Q) of the aircraft cabin substantially perpendicularly to the main aisle (101) and an aircraft monument (10) arranged in the door aisle (102) and comprising at least one flight attendant seat (14, 14') facing a section of the main aisle (101) adjoining the door aisle (102).
