Duplex Airplane Seat System with Vertical Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional airplane seat systems, particularly in first and business classes, face challenges in space efficiency and cost, making it difficult to provide a luxurious and stable cabin environment while maintaining high seat prices, which limits demand.
Innovation Solution
A seat system that combines an upper and lower seat system with various arrangement structures such as V-shaped, linear, and hatched configurations, allowing for continuous arrangement of seat parts and incorporating support partitions and accommodating bodies to block lines of sight, while also providing additional features like monitor and table integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional first and business class seats are provided with wide space, then passenger comfort is improved, but space efficiency deteriorates and seat price increases
Solution Approach 1:
The patent applies vertical stacking of seat rows to utilize the third dimension (height) of the cabin space. Upper seats are positioned above lower seats, transforming the traditional horizontal arrangement into a vertical configuration. This dimensional change allows the aircraft to maintain comfortable seat spacing while increasing the number of seats per cabin volume, thereby resolving the contradiction between passenger comfort and space efficiency.
Solution Approach 2:
The cabin is segmented into multiple levels with upper and lower seat systems. Each level is further divided into separate seat parts (upper seat parts and lower seat parts) that can be independently arranged. This segmentation allows for optimized space utilization at each level while maintaining overall comfort standards, addressing both the comfort and space efficiency requirements.
2Ease of operation
If conventional first and business class seats are provided with wide space, then passenger comfort is improved, but seat price increases limiting demand
Solution Approach 1:
The upper and lower seat systems share common structural components, support mechanisms, and design specifications. The same seat modules are used across different levels, allowing for standardized manufacturing and reduced development costs. This universality enables the airline to offer enhanced comfort at a lower price point by eliminating redundant systems and leveraging economies of scale.
3Productivity
If duplex seat arrangement is adopted to improve space efficiency, then space efficiency is improved, but interior accommodation becomes burdensome
Solution Approach 1:
The duplex seat system is divided into modular upper seat parts and lower seat parts that can be independently installed and adjusted. Each module is designed as a self-contained unit with standardized interfaces, simplifying the interior accommodation process. This segmentation allows for easier installation, maintenance, and reconfiguration compared to a fully integrated system.
Solution Approach 2:
The seat system incorporates adjustable and reconfigurable elements that allow the interior arrangement to be adapted to different operational requirements. Support partitions and accommodating bodies can be positioned or removed as needed, providing dynamic flexibility in interior accommodation while maintaining space efficiency.
