Aircraft Seat Tray Table Mounting for Multi-Axis Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger seat designs face challenges in providing flexible usability and comfort while adhering to safety standards, particularly in adapting functions within a limited space and accommodating varying aircraft orientations during flight.
Innovation Solution
A passenger seat with a pivotable table top attached to a structural component via a joint arrangement, allowing for precise adjustment in multiple directions (height, side, and inclination) to ensure the table top remains horizontal during flight, using a connecting arrangement with screw connections for stable and space-efficient adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table top is fixed in a single position, then the structure is simple and stable, but the adaptability and user comfort are limited
Solution Approach 1:
The table top is made adjustable through a joint arrangement with pivot axis, allowing dynamic repositioning between multiple mounting positions. The connection arrangement includes adjustment means that enable the table top to be positioned at different heights and angles, transforming a static structure into a dynamic one that adapts to user needs.
Solution Approach 2:
The mounting structure is divided into separate components: a connection arrangement with first and second connection components, and a joint arrangement with pivot axis. This segmentation allows independent adjustment of different parameters (position, angle) while maintaining overall structural integrity and simplifying the design of each individual component.
2Adaptability or versatility
If the table top is made adjustable in multiple directions, then user comfort and adaptability improve, but the structural complexity increases
Solution Approach 1:
The connection arrangement and joint arrangement are merged into a single integrated mounting structure. The first connection component attaches to the structural component, the second connection component attaches to the table top, and the joint arrangement with pivot axis connects these components, combining multiple functions (attachment, pivoting, adjustment) into one unified system.
Solution Approach 2:
The joint arrangement serves multiple functions simultaneously: it acts as a connection point between structural components, provides a pivot axis for rotation, enables multi-directional adjustment, and maintains structural stability. This multi-functionality reduces the need for separate mechanisms for each adjustment parameter.
3Manufacturing precision
If the table top is made pivotable with adjustment means, then precision and user comfort improve, but the ease of operation decreases
Solution Approach 1:
The adjustment means are designed to be operated directly by the user without requiring additional tools or complex procedures. The connection arrangement allows the user to easily adjust the table top to desired positions through intuitive manipulation of the joint arrangement, making the precision adjustment system self-servicing.
