Passenger Seat Tray Table with Movable Cup Holder for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tray table devices for aircraft passenger seats lack improved comfort, user-friendliness, and safety, particularly in terms of cup holder functionality and space efficiency, while also being prone to damage and high fabrication costs.
Innovation Solution
A tray table device with a movably mounted cup holder unit that integrates with the table unit to form a holding recess, featuring a dual-function design that allows for compact construction, easy handling, and retrofit capability, with the cup holder unit being swivel or sliding-mounted to adapt to different positions and provide intuitive use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cup holder unit is integrated into the tray table, then comfort and usability are improved, but device complexity increases
Solution Approach 1:
The cup holder unit is integrated into the tray table device, merging two functions (table and cup holder) into a single device. This allows the cup holder to be provided in a position of use without requiring a separate structure, thereby improving comfort and usability while managing device complexity through functional integration.
Solution Approach 2:
The tray table device is designed to serve multiple functions: it acts as both a table surface and a cup holder. The cup holder unit can be positioned in use or folded away, providing versatility. This multi-functionality improves ease of operation by consolidating needs into one device without significantly increasing overall structural complexity.
2Adaptability or versatility
If the cup holder unit is movably mounted to the table unit, then adaptability and space efficiency are improved, but manufacturing precision requirements increase
Solution Approach 1:
The cup holder unit is movably mounted to the table unit, allowing it to transition between a position of use and a folded position. This dynamic configuration improves adaptability and space efficiency, as the cup holder can be adjusted or stored as needed. The movable mounting mechanism accommodates variations in assembly tolerances, reducing the stringency of manufacturing precision requirements.
Solution Approach 2:
The cup holder unit can be folded into or nested within the tray table structure when not in use. This nesting capability maximizes space efficiency by minimizing the occupied volume during storage, while the movable mounting allows for easy deployment without requiring high-precision fixed positioning.
3Volume of moving object
If the cup holder unit and table unit together implement the holding recess, then space efficiency is improved, but reliability may worsen
Solution Approach 1:
The holding recess is formed by the combined structure of the cup holder unit and the table unit. When the cup holder unit is in the position of use, its outer contour together with the table unit implements the holding recess that receives the drinking vessel. This merged structure achieves space efficiency by utilizing the available volume effectively, while the cooperative design of both units ensures reliable vessel support through distributed load-bearing surfaces.
