Staggered Herringbone Aircraft Seating for Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft premium class seating systems face challenges in maximizing space utilization while maintaining comfort, particularly on single-aisle aircraft, where deeper recline and wider seats limit seat density and require innovative arrangements to accommodate auxiliary comfort features.
Innovation Solution
The seating arrangement features staggered herringbone configurations of seat units with independently reclining seats that maintain side-by-side alignment, allowing direct access to both seats from the aisle, and can form group seating areas, optimizing space through angled and X-shaped configurations, and providing separate or shared egresses for enhanced comfort and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If deeper recline and wider seats are provided to increase passenger comfort, then comfort is improved, but space utilization deteriorates
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional straight longitudinal seat rows to angled herringbone configurations. Seats are positioned at angles (e.g., 15-45 degrees) relative to the aisle, transforming the spatial arrangement from a one-dimensional linear pattern to a two-dimensional angular pattern. This allows deeper recline and wider seats to be accommodated within the same cabin footprint by utilizing angular space more efficiently.
Solution Approach 2:
The patent segments the cabin into multiple angled rows with staggered positioning, where each row is offset from the aisle by different distances. This segmentation creates a herringbone pattern that allows independent optimization of each seat's comfort parameters (recline angle, width) while maintaining overall space efficiency through the modular repeated pattern.
2Ease of operation
If more premium class seating is provided to increase comfort, then comfort is improved, but seat density deteriorates
Solution Approach 1:
By changing from straight rows to angled herringbone configurations, the patent increases the effective use of cabin space. The angular arrangement allows seats to be positioned closer together in the longitudinal direction while maintaining adequate lateral space for comfort, thereby increasing seat density without sacrificing premium comfort features.
Solution Approach 2:
The patent changes the geometric parameters of seat arrangement from traditional 90-degree perpendicular rows to angled configurations (15-45 degrees). This parameter change optimizes the spatial relationship between adjacent seats, allowing more seats to be accommodated in the same cabin volume while maintaining comfortable spacing and access.
3Ease of operation
If seats are angled to provide direct access from aisle, then ease of access is improved, but space configuration complexity increases
Solution Approach 1:
The patent segments the cabin into repeated modular units, each consisting of angled seat rows with consistent herringbone patterns. This segmentation allows the complex angled configuration to be broken down into simple repeating units that can be systematically arranged, reducing the overall complexity through modularity while maintaining easy access for each seat.
Solution Approach 2:
The patent employs asymmetric angular positioning of seats relative to the aisle, with each seat row offset at specific angles (e.g., 15-45 degrees). This asymmetric arrangement creates direct access paths for passengers while the repetitive application of the same asymmetric pattern throughout the cabin creates predictability and reduces configuration complexity.

AI summary
A passenger seating arrangement for an aircraft cabin is disclosed. A plurality of seat units each comprise at least a first reclining seat and a second reclining seat. The seat units are located in a column adjacent to a longitudinal aisle of the aircraft cabin. The first reclining seat and the second reclining seat of the seat units are configured to have substantially similar plan view contour and side-by-side alignment when similarly reclined. The seat units are angled to the aisle to provide a direct access from the aisle to the first and second reclining seats of the seat units. The seat units in the column are arranged in a staggered herringbone configuration relative to the aisle.
