Inflatable Bed Backrest Slit Structure for Flush Deflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing foldable backrest design in inflatable beds, where an additional air pouch is sandwiched between the backrest and the primary body, prevents the backrest from being fully deflated, limiting adjustability and comfort.
Innovation Solution
An inflatable bed with a slit defined between the backrest and the primary body, featuring complementary angles to facilitate the raising of the backrest, and an air pouch within the slit to provide selective support and tilt, along with a skirt and baffles to maintain shape and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional air pouch is sandwiched between the backrest and the primary body to enable foldable backrest, then the backrest can be tilted to provide comfort, but the backrest cannot be fully deflated to flush with the primary body
Solution Approach 1:
The air pouch is segmented into two separate chambers: a first chamber between the backrest and primary body for tilt adjustment, and a second chamber within the primary body for overall support. This segmentation allows independent control of backrest angle and bed firmness, enabling the backrest to be fully deflated to flush with the primary body when needed.
Solution Approach 2:
The air pouch is extracted from a single integrated structure and divided into separate functional chambers. The first chamber is specifically extracted and positioned to enable backrest tilting, while the second chamber remains within the primary body, allowing the backrest to be completely deflated and aligned with the primary body surface.
2Reliability
If check valves are provided to communicate the backrest with the primary body and air pouch to prevent air escape, then the bed maintains inflation, but the structure becomes more complex
Solution Approach 1:
The check valves serve multiple functions: they maintain air pressure in the first chamber for backrest tilt, maintain air pressure in the second chamber for primary body support, and prevent air escape during deflation. This multi-functionality reduces the need for separate valve systems for each chamber, simplifying the overall structure while maintaining reliability.
3Ease of operation
If the air pouch is inflated to support the backrest at an angle, then user comfort is improved, but the backrest cannot be flattened for compact storage
Solution Approach 1:
The backrest is designed with dynamic adjustability through the first air chamber, allowing it to transition between inflated (tilted) and deflated (flush) states. This dynamic capability enables the backrest to adapt between providing user comfort at an angle and achieving a compact flat profile for storage or transport.
Solution Approach 2:
The volume and pressure parameters of the first air chamber are changed to achieve different backrest configurations. When inflated, the chamber provides tilt support for user comfort; when deflated, the backrest flattens against the primary body, minimizing the bed's overall profile and volume for compact storage.
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
Enables the backrest to be easily adjusted and tilted, providing enhanced comfort and support while maintaining the bed's shape and preventing deformation, even when the air pouch is fully deflated.
Implementation Method 1
an air pouch inflatably received in the slit to selectively support a user and tilt the backrest relative to the primary body
Implementation Method 2
baffles formed between the top side and the bottom side to sustain shape of and to form compartments in the inflatable bed

AI summary
An inflatable bed having a primary body, a backrest selectively inclinable relative to the primary body, a slit defined at a junction of the primary body and the backrest, and a pouch received in the slit to be selectively inflatable to move the backrest relative to the primary body. The slit is defined in a manner that when the pouch is inflated and the backrest is lifted by the pouch, friction of a bottom face of the backrest to a top face of ground where the inflatable bed is rested is minimized so as to facilitate the inclinable movement of the backrest relative to the primary body.
