Aircraft Suite Layout with Angular Offset for All Aisle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft seating arrangements in narrow body, single aisle aircraft compromise privacy and density by limiting the number of suites that can be positioned abreast and requiring passengers to ingress and egress through adjacent suites, disrupting privacy and limiting orientation to either forward or aft directions.
Innovation Solution
A seating arrangement that positions five suites abreast with each suite having a privacy wall and a movable seat between seating and lie-flat positions, allowing angular offsets to define unique ingress/egress paths and staggered seating to prevent overlap, enabling all suites to face in the same direction without invading privacy, and incorporating ottomans in foot wells for forming lie-flat beds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suites are positioned abreast in narrow body aircraft, then density is improved, but privacy is compromised due to passengers needing to ingress/egress through adjacent suites
Solution Approach 1:
The patent applies angular offset to suite longitudinal axes, creating diagonal ingress/egress paths that traverse across the cabin rather than through adjacent suites. This dimensional change in path orientation allows suites to be positioned abreast while maintaining privacy, as passengers move through cabin space above or below adjacent suite footprints rather than through them.
Solution Approach 2:
The patent segments the cabin space by positioning suites in longitudinally-offset rows with angular offsets, creating distinct ingress/egress zones for each suite. This segmentation allows multiple suites to be accessed independently from the aisle without requiring passage through neighboring suites, thereby maintaining privacy while achieving high density.
2Quantity of substance
If suites are positioned abreast, then the number of suites increases, but all suites cannot face the same direction due to space constraints
Solution Approach 1:
The patent employs asymmetric angular offsets for suites in different lateral positions. Suites on opposite sides of the aisle have different angular offsets relative to the cabin longitudinal axis, allowing all suites to face forward while accommodating the geometric constraints of abreast positioning. This asymmetric arrangement enables uniform forward-facing orientation across all suites despite their different lateral locations.
3Productivity
If suites require ingress/egress through adjacent suites, then density is maximized, but passenger comfort deteriorates due to privacy invasion
Solution Approach 1:
The patent introduces cabin aisle space as an intermediary zone that mediates between suites positioned abreast. By routing ingress/egress paths through this intermediate cabin space rather than through adjacent suites, the system maintains suite density while protecting passenger comfort and privacy. The aisle acts as a buffer zone that enables independent suite access.

AI summary
Passenger seating groups positionable in a column in an aircraft between a longitudinal aisle and a fuselage wall. Each passenger seating group includes a first passenger seat positioned along an aisle side and facing a first direction, a first footwell positioned along the aisle side and facing the first passenger seat, a second passenger seat positioned along the wall side and facing the first direction, and a second footwell positioned along the wall side and facing the second direction to serve a second passenger seat in an adjacent like seating group. Each seat has its own dedicated entry from the longitudinal aisle and seats within the same seating group are physically separated by privacy walls.
