Backpack Sleep Support Structure for Upright Travel Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport vehicle seats, such as airline seats, do not provide sufficient support for comfortable upright sleep due to limited reclination and existing solutions like neck pillows or tray tables are inadequate, often causing discomfort, neck strain, and disruption of breathing or vision during sleep.
Innovation Solution
A portable sleep support system integrated into a backpack with a head cushion and chest cushion, featuring a hinged support structure for angular adjustment, straps for secure attachment to a vehicle seat, and additional features like standoff supports and a stabilizing strap to prevent intrusion and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a neck pillow is used to support the head in an upright position, then head support is provided, but the pillow filling materials shift or deform during use and the covers are non-breathable
Solution Approach 1:
The sleep support system is divided into separate functional components: a head support portion with breathable cover, a chest support portion, and connecting straps. This segmentation allows each component to be optimized independently - the head support can focus on breathability while the chest support provides stability, resolving the contradiction between comfort and reliability.
Solution Approach 2:
The system incorporates adjustable straps and flexible connecting elements that can adapt to different body positions and movements. The dynamic adjustment capabilities allow the support structure to maintain reliability while accommodating natural movements, preventing the filling shift and deformation problems of static pillows.
2Volume of moving object
If an inflatable neck pillow is used to reduce transport space, then storage space is reduced, but inflation and deflation are required at beginning and end of use
Solution Approach 1:
The sleep support system is pre-assembled in a compact configuration within the backpack, with all components (head support, chest support, straps) already in position. This preliminary preparation eliminates the need for inflation/deflation operations, allowing quick deployment and storage without time-consuming setup while maintaining compact form factor.
3Ease of operation
If the tray table is used as a support surface by adding objects to raise the level, then arm and head support is achieved, but the space available is determined by the person in front and may impact their ability to adjust their seat
Solution Approach 1:
The sleep support system introduces a personal support structure that acts as an intermediary between the passenger and the seat/tray table environment. This self-contained system provides the necessary support surfaces independently, eliminating dependency on the tray table configuration and the person in front, thus resolving the contradiction between获得 support and maintaining adaptability.
4Area of stationary object
If the seat back is reclined to create space for a support on the tray table, then space for support is created, but no room remains to place a support on the tray table
Solution Approach 1:
The sleep support system transitions the support function from the horizontal tray table dimension to a vertical configuration using the backpack and chest support. By utilizing the vertical space along the body rather than horizontal tray table space, the system creates support surfaces without requiring seat back reclination, resolving the spatial contradiction.

AI summary
An upright sleep support system incorporates a head cushion having a face relief aperture to receive the eyes, nose, mouth and chin of a passenger placing his or her face against the head cushion with a hinged support structure for angular adjustment, sleeves that open in front to support the passengers arms, and a chest cushion on the back of the device. The chest cushion receives the passenger's chest in a forward leaning position. The head cushion is deployable from a backpack and the chest cushion is integrated into the back of the backpack.
