Solution Overview
Problem
Existing sleeping devices for travel, such as in cars, planes, or trains, are uncomfortable and lead to strain and discomfort, failing to provide adequate support for users, especially when space is limited.
Innovation Solution
A portable sleeping device with a vertical frame, inflatable cushions, and u-shaped top and bottom members connected by hinges, allowing for ergonomic support and collapsibility for easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable sleeping device provides ergonomic support with cushions and frame structure, then comfort and sleep quality are improved, but device complexity and size increase
Solution Approach 1:
The device is divided into separate functional components: a U-shaped frame structure, removable cushions (head cushion, back cushion, armrest cushions), and an inflatable base. This segmentation allows each component to be optimized independently for comfort while enabling compact storage when collapsed.
Solution Approach 2:
The device incorporates adjustable elements including inflatable cushions that can be adjusted to different firmness levels, removable cushions that can be repositioned or taken off, and foldable frame sections that transition between compact and expanded states, providing dynamic adaptability to user needs.
2Ease of operation
If the device is made collapsible for easy transport, then portability is improved, but structural stability may be compromised
Solution Approach 1:
The frame is segmented into multiple hinged sections that can fold together for compact storage yet form a stable U-shaped structure when deployed. The segmentation with hinge connections allows both portability and structural integrity.
Solution Approach 2:
The device includes pre-attached cushions and pre-configured hinge mechanisms that maintain structural stability when deployed. The cushions are pre-positioned to provide immediate support, and the hinge design ensures stable configuration upon opening.
3Ease of operation
If additional cushions and support structures are added to enhance comfort, then sleep quality is improved, but device weight increases
Solution Approach 1:
The device uses an inflatable cushion system for the base and armrests, allowing adjustment of support firmness without adding significant weight. Air-filled structures provide cushioning and support while remaining lightweight compared to solid foam or rigid materials.
Solution Approach 2:
The inflatable cushions allow users to change the firmness parameter by adjusting air pressure, providing varying levels of comfort without changing the physical mass of the device. This enables comfort customization while maintaining portability.

AI summary
The present invention relates to a portable sleeping device primarily comprised of a body that is further comprised of at least one vertical frame member, at least one bottom member with at least one inflatable cushion, at least one top member, at least one cushion and at least one carrying case. The vertical frame member holds the device upright while at least one hinge attaches both the top member and bottom member to the vertical frame at a 90-degree angle. A cushion within a cover is removably attached to the top member to enhance the device's comfort. Both the cushion and the top member are generally u-shaped. The bottom member features an inflatable cushion also within a cover to further increase comfort. To use the device, a user can lean forward and rest his or her head on the cushion.
