Angled Lounge Seating Layout for Space-Efficient Aircraft Cabins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current passenger seating arrangements in aircraft cabins are inefficient in terms of space usage, as they consume a large amount of space while providing comfort, which increases operating costs due to the physical size and aerodynamic drag of the fuselage.
Innovation Solution
The proposed seating arrangement features angled and offset seat units with moveable components, including ottomans and leg rests, allowing for a comfortable sleeping position while minimizing space consumption by angling the central axes of the seat units relative to the aircraft's longitudinal axis, enabling side-by-side positioning of ottomans and reducing overall cabin width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional parallel sleeper seats are used, then passenger comfort is improved, but cabin space efficiency deteriorates
Solution Approach 1:
The patent transitions from traditional parallel seat arrangement to an angled configuration where seats are disposed at angles (e.g., 45 degrees) relative to the cabin center line axis. This dimensional change in spatial arrangement allows ottomans to be positioned side-by-side laterally, significantly reducing the longitudinal space required while maintaining comfortable sleeping positions.
Solution Approach 2:
The patent employs asymmetric positioning of seat units relative to the cabin center line, with seats angled at specific orientations rather than parallel to the axis. This asymmetric arrangement optimizes space utilization by allowing ottomans to nestle laterally adjacent to each other, reducing overall cabin footprint while preserving comfort.
2Ease of operation
If larger cabin size is used to accommodate comfortable seats, then passenger comfort is improved, but operating costs increase
Solution Approach 1:
By reorienting seats at angles to the cabin axis and positioning ottomans in a lateral side-by-side arrangement rather than end-to-end, the patent reduces the longitudinal dimension required. This dimensional optimization allows smaller cabin sizes while maintaining comfort, directly reducing aerodynamic drag and operating costs.
3Area of stationary object
If angled seat configuration is used, then space efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the seating system into modular units, each comprising a seat and an associated ottoman that can be independently positioned and angled. This segmentation allows the angled configuration to be implemented as a series of discrete, manageable modules rather than a complex integrated system, reducing overall complexity.

AI summary
A passenger seating arrangement includes a first seat unit, facing in a first direction; a first ottoman having a first support surface positioned to receive the feet of a passenger seated in the first seat unit; a second seat unit facing in a second direction generally opposite to the first direction; and a second ottoman disposed laterally adjacent to the first ottoman and having a second support surface positioned to receive the feet of a passenger seated in the second seat unit.
