Angled Four-Suite Aircraft Seating Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft passenger seating arrangements face challenges in optimizing seating density, spatial efficiency, comfort, and privacy, particularly in narrow and wide body aircraft, where traditional layouts often compromise on one aspect due to the need for legroom, emergency access, and structural integrity.
Innovation Solution
The proposed seating arrangement features a four-suite unit with angled forward and aft-facing seats, allowing for direct access from the aisle and shared passageways, along with privacy dividers and ottomans, which enables efficient use of space while maintaining passenger comfort and safety by angling seats relative to the aircraft axis, thereby optimizing density and spatial efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lie-flat seating is provided to improve passenger comfort, then passenger comfort is improved, but seating density decreases due to increased seat pitch requirements
Solution Approach 1:
The patent transitions from traditional longitudinal seat arrangement to a radial configuration where seats are oriented at angles (e.g., 45 degrees) relative to the aircraft longitudinal axis, allowing lie-flat functionality while reducing the longitudinal space requirement from approximately double economy class pitch to a more compact arrangement that fits within standard cabin dimensions
Solution Approach 2:
The seats are designed to be convertible between upright sitting position for taxi, take-off and landing (TTOL) and a lie-flat sleeping position in-flight, allowing the seat configuration to dynamically adapt to different operational phases and passenger needs
2Productivity
If seats are arranged to maximize seating density, then seating density is improved, but passenger comfort deteriorates due to reduced legroom and space
Solution Approach 1:
By orienting seats radially at angles to the longitudinal axis rather than strictly longitudinally, the patent achieves higher seating density while maintaining adequate legroom and personal space, as the radial arrangement distributes passengers more evenly across the cabin cross-section
Solution Approach 2:
The patent combines multiple functions into the radial seat arrangement: seating, sleeping (lie-flat), and efficient space utilization are all achieved within the same configuration, eliminating the need to trade off between density and comfort
3Ease of operation
If traditional longitudinal seat arrangement is used, then ease of access is improved, but spatial efficiency deteriorates due to wasted space and confined feel
Solution Approach 1:
The radial arrangement at angles (e.g., 45 degrees) to the longitudinal axis creates more efficient use of cabin space by utilizing the cross-sectional area of the fuselage more effectively, reducing wasted space between rows and along the walls while maintaining accessible pathways
4Area of stationary object
If overlapping seat arrangements are used to conserve space, then spatial efficiency is improved, but passenger privacy deteriorates as passengers must pass through each other's space
Solution Approach 1:
The radial seat arrangement naturally segments the cabin into distinct seating zones radiating from the center, with each seat having its own defined space and access path, eliminating the need for passengers to pass through each other's space while maintaining high spatial efficiency

AI summary
A travel suite arrangement for an aircraft cabin, such as a business class cabin, including at least one longitudinal aisle dividing sections, with each section including at least one four-suite unit. Each four-suite unit generally includes an angled first seat positioned directly adjacent the longitudinal aisle forward-facing, a second angled seat positioned directly adjacent the longitudinal aisle rearward-facing, a third angled seat positioned apart from the longitudinal aisle, to one side of the first seat and rearward-facing, and a fourth angled seat positioned apart from the longitudinal aisle, to one side of the second seat and forward-facing. Aisle seats are accessed directly from the aisle while outboard seats share access passageways.
