Deployable Tray Table With Detachable Hinged Proximal Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deployable tray tables require more cleaning and maintenance due to their separation, and replacing the proximal portion for advertising can be cumbersome, necessitating disassembly of the entire table.
Innovation Solution
A deployable tray table with two portions that can rotate 180° from a folded position to an extended position, allowing quick separation for cleaning, maintenance, or replacement, with a proximal portion providing an additional resting plane and cup-holding cavity, and a support for tablets or smartphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tray table is divided into two separate portions hinged to each other, then the tray table can be rotated to provide an additional resting plane and adapt to different space requirements, but the cleaning and maintenance become more difficult due to the separation
Solution Approach 1:
The tray table is divided into two separate portions (first and second portions) that can be independently handled for cleaning and maintenance, while still functioning together as a complete tray table when assembled. This segmentation allows each portion to be cleaned separately, improving maintenance ease while maintaining adaptability through the hinged connection between portions.
2Device complexity
If the proximal portion is fixed to the distal portion, then the structure is simpler and easier to maintain, but the tray table cannot be rotated to provide an additional resting plane or adapt to different configurations
Solution Approach 1:
The hinge connection between the first and second portions allows the tray table to dynamically change its configuration. The proximal portion can be rotated relative to the distal portion to provide an additional resting plane when needed, while maintaining structural simplicity through the straightforward hinged joint design that requires no complex mechanisms.
3Stability of the object's composition
If the entire tray table must be disassembled for replacement of the proximal portion, then the structural integrity is maintained, but the replacement time and complexity increase significantly
Solution Approach 1:
The tray table is segmented into two portions connected by a hinge, allowing the proximal portion to be replaced independently by simply detaching and reattaching the hinge connection. This maintains structural integrity through the robust hinged joint while dramatically improving replacement ease by eliminating the need to disassemble the entire tray table.

AI summary
A deployable tray table, of the type revolvingly constrained to a support and movable between a horizontal operating position and an upwardly rotated position, comprises a distal portion, near to the support, and a proximal portion which are placed side by side and adjacent, divided by a separation in which adjacent edges of the two portions are joined by means of respective hinges, so that the proximal portion could rotate by 180° from a folded position in a configuration with reduced overall dimensions, in which said hinges comprise each one a respective hinge pin retractable in the respective portion, so as to be able to disengage and separate the proximal portion from the distal portion.
