Structure of inflatable bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses, especially those for larger beds, face challenges in shipping and transportation due to their weight and size, and existing inflatable beds lack sufficient cushioning and adjustability to provide comfort and support in multiple directions.
Innovation Solution
An inflatable bed structure combining an inflatable mattress with an inflatable frame, featuring elastic braided bands that provide mutual stretching for cushioning in multiple directions, along with a Drop-stitching construction fabric and thermoplastic polyurethane tubular bodies, allowing for adjustable stiffness and easy deflation for storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional mattresses are used to provide comfort and support, then cushioning effect is improved, but weight increases resulting in greater burden for shipping and transportation
Solution Approach 1:
The patent uses inflatable structures filled with air to provide cushioning and support. The mattress and frame are both inflatable, using pneumatic pressure to create a lightweight yet supportive sleeping surface that eliminates the need for heavy traditional spring coils while maintaining comfort.
Solution Approach 2:
The patent employs flexible inflatable chambers and thin-walled structures to create the mattress and frame. These flexible shells can be inflated to provide structural support and cushioning, then deflated for compact storage and transportation, significantly reducing weight and volume compared to conventional rigid mattress structures.
2Strength
If mattresses are made up of multiple independent spring coils to improve comfortability, then bearing capability is improved, but weight increases resulting in even greater burden for shipping and transportation
Solution Approach 1:
The patent replaces heavy spring coil systems with inflatable pneumatic structures. The air-filled chambers provide the necessary bearing capability and support through pneumatic pressure, eliminating the need for numerous metal springs while maintaining comfort and load-bearing performance.
Solution Approach 2:
The patent uses composite construction combining inflatable materials with elastic braided bands and fabric layers to create a lightweight structure that provides both support and comfort. This composite approach replaces heavy metal springs with a combination of pneumatic and elastic materials.
3Strength
If elastic braided bands are arranged on the inflatable frame to provide cushioning in multiple directions, then comfortability is improved, but device complexity increases
Solution Approach 1:
The elastic braided bands serve multiple functions simultaneously: they provide cushioning in horizontal directions, support the inflatable mattress, and work together with the inflatable frame to create multi-directional support. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The patent combines the frame structure with cushioning elements by integrating elastic braided bands directly onto the inflatable frame. This merging of structural and cushioning functions into a single integrated system reduces overall device complexity while providing multi-directional support.

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 inflatable bed offers enhanced comfort and support in both vertical and horizontal directions, with adjustable stiffness and ease of storage and transportation, addressing the limitations of conventional mattresses by providing a lightweight and flexible sleeping solution.
Implementation Method 1
the elastic braided bands and the inflatable frame that are so coupled may provide mutual stretching therebetween that achieves effects of cushioning simultaneously in multiple directions

AI summary
An improved structure of inflatable bed includes: an inflatable mattress having an upper surface, a lower surface, and a lateral side structure that has upper and lower edges respectively connected to edges of the upper and lower surfaces so that the inflatable mattress is formed with an air charging space, the lateral side structure including a first charging valve in communication with the air charging space, the air charging space being provided therein with a Drop-stitching construction fabric having upper and lower ends respectively connected to the upper and lower surfaces; and an inflatable frame including at least one inflatable tubular body and outer layer cloth covering the inflatable tubular body. The inflatable tubular body includes a second charging valve. The inflatable frame is positioned on a bottom side of the inflatable mattress. The inflatable frame includes elastic braided bands to prevent undesired outward expansion of the inflatable frame after inflation.
