Aircraft Seating Assemblies With Staggered Angled Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft seating arrangements face a compromise between passenger comfort and seating density, with premium economy seats typically offering only increased width, which negatively impacts seat density, and business class bed options further reducing density.
Innovation Solution
The implementation of staggered and angled seating configurations, where one seat is positioned forward of the other, allowing for overlapping armrests and increased shoulder space, while angling the seats to improve legroom and reduce visual encroachment, thereby enhancing comfort without compromising density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If premium economy seats are made bigger and wider to improve comfort, then passenger comfort is improved, but seat density decreases
Solution Approach 1:
The patent applies staggered seating where seats are offset in the longitudinal dimension rather than being aligned in straight rows. This dimensional change allows seats to be positioned closer together laterally while maintaining adequate legroom and comfort, effectively resolving the contradiction between seat width/comfort and seat density by utilizing three-dimensional space more efficiently
Solution Approach 2:
The patent employs asymmetric seat positioning where alternating seats are offset forward or backward relative to the aisle centerline. This asymmetric arrangement creates overlapping armrest configurations and varied passenger spacing patterns that maximize both individual comfort and overall seat density, preventing the monotony and space waste of symmetric arrangements
2Quantity of substance
If seats are positioned in straight rows to maximize density, then seat density is improved, but passenger comfort and legroom deteriorate
Solution Approach 1:
By offsetting seats in the longitudinal dimension (creating staggered rows rather than straight alignment), the patent enables increased lateral spacing and legroom for each passenger while maintaining high overall seat density. The staggered configuration uses the third dimension (depth/longitudinal position) to create comfort space without sacrificing density
3Ease of operation
If armrests are positioned far apart to provide dedicated space, then shoulder space is improved, but seat width is reduced
Solution Approach 1:
The staggered seating arrangement offsets seats longitudinally, allowing armrests to overlap in the lateral dimension while maintaining adequate clearance in the longitudinal dimension. This dimensional offset provides dedicated shoulder space for each passenger without requiring full lateral separation, thereby preserving seat width

AI summary
A seating assembly may employ one or more of: a seat stagger, a seat overlap, and a seat angling to offer significant width and comfort gains and reduce the negative impact of width and leg room gains on seating density. With one seat of a pair staggered forward with respect to the other seat each may then be moved laterally and overlap (as seen from the front). The seating positions may be further improved by angling each seat away from their center arm rest area, reducing the encroaching effect of the overlap by pointing the passenger away from the overlap, reducing the visual impact of the staggered seating by pointing the passenger away from the nearest seat ahead, and improving leg room by directing the passenger's legs forward at an angle.
