Solution Overview
Problem
Aircraft seat devices face challenges in optimizing space and weight requirements while maintaining functionality, particularly in transitioning between use and stowage positions.
Innovation Solution
The design incorporates a base body with pivotally connected plates that adjust through a hinge element and joint elements, allowing for significant depth extension changes between functional positions, enabling a compact stowage position and expanded use position, with a table surface that can be aligned parallel to the seat support plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a table device is integrated into the aircraft seat with extended depth for use position, then functionality and comfort are improved, but space requirements and weight increase
Solution Approach 1:
The table device is designed with dynamic depth extension capability, allowing it to change from a retracted state during flight to an extended state during landing/taxiing. The depth extension device includes movable elements that can protrude from the seat structure, transforming the table from a compact storage configuration to a functional extended configuration based on operational requirements.
2Adaptability or versatility
If the base body is designed with large depth extension for use position, then functional performance is improved, but space consumption in stowage position increases
Solution Approach 1:
The base body is segmented into multiple depth sections that can be independently adjusted. The depth extension device is divided into separate movable segments that can be extended or retracted independently, allowing the table to achieve functional depth when needed while maintaining a compact profile during stowage by retracting only the necessary extension segments.
3Adaptability or versatility
If multiple adjustment mechanisms are added to achieve depth extension, then adaptability is improved, but device complexity increases
Solution Approach 1:
The depth extension device is merged with the existing table structure and support mechanisms. The extension mechanism integrates with the seat's current adjustment systems, sharing common components such as mounting structures, control systems, and structural supports, thereby reducing overall complexity despite adding adaptability functionality.
