Foldable Sleeping Table With Adjustable Head Support in Tight Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for sleeping on public transportation, such as airplanes and buses, are either bulky, inflexible, or not adaptable to different heights, making them uncomfortable and difficult to use in cramped spaces.
Innovation Solution
A portable, adjustable, and foldable sleeping device with a removable pillow support that allows for adjustable height and angle, featuring a base that pivots and can be easily moved, secured with Velcro, and includes a slot for electronic devices, enabling comfortable sleeping and reading positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inflatable pillow is used, then head support is provided, but the device becomes bulky and difficult to stow
Solution Approach 1:
The device is divided into separate components: a compact base unit with adjustable support surface, and a removable pillow. This segmentation allows the main support structure to remain compact while providing full functionality, eliminating the need for bulky inflatable elements.
Solution Approach 2:
The support surface is made dynamically adjustable through telescopic legs and rotating mechanisms, allowing the user to change height and angle settings. This dynamic adjustment replaces the need for multiple fixed-size inflatable pillows, reducing overall device volume while maintaining versatility.
2Volume of moving object
If a single sized inflatable pillow is used, then it can be carried easily, but it cannot be comfortable for people of different heights
Solution Approach 1:
The telescopic legs enable continuous height adjustment, and the rotating support surface provides angle variability. This dynamic adjustability allows the same compact device to accommodate users of various heights and preferences, replacing the need for multiple fixed-size pillows.
Solution Approach 2:
The single base unit serves multiple functions: it can be adjusted to different heights, angles, and positions, and the removable pillow can be used in various configurations. This multi-functionality eliminates the need for multiple specialized pillows for different user types.
3Ease of operation
If an inflatable pillow is inflated, then head support is provided, but it prevents passengers from adjusting their seats
Solution Approach 1:
The adjustable support surface can be rotated and repositioned dynamically, allowing users to maintain comfortable head support even when front seats are adjusted. The removable pillow design also allows temporary relocation or removal when seat adjustment is needed, maintaining both head support functionality and seat adjustment freedom.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a compact, versatile, and comfortable sleeping solution for various heights, allowing users to adjust the pillow support and base for optimal comfort, while being easy to set up, use, and stow, accommodating different passenger needs and space constraints.
Implementation Method 1
The pillow is removable from the pillow support by attaching it to the pillow support with Velcro® brand hook and loop fastener or other temporary securing means.

AI summary
A folding portable sleeping table comprises a planar member rotatably connected to at least one longitudinal support member. A support arm has a proximal and a distal end. The proximal end of the support arm is rotatably connected to the planar member. The longitudinal support member has notches to engage the distal end of the support arm. The longitudinal support member has a hollow interior sized to accept at least one extendable member. A base member is positioned on a lower end of the at least one extendable member. The at least one extendable member is adjustably secured to the at least one longitudinal support member whereby the base member and the at least one extendable member can extend in and out relative to the at least one longitudinal support member.
