Inflatable bed with mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable beds with traditional construction methods result in a hard surface when inflated, compromising comfort due to the stretching of waterproof cloth, which affects user experience.
Innovation Solution
An inflatable bed design incorporating a mattress with a sandwich structure comprising a cloth adhesion layer, a sponge layer, and another cloth adhesion layer, along with a connecting side panel that forms a gas chamber and exhaust holes for improved stability and comfort, allowing for gas exchange between the mattress and bed body, facilitating easier storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bed body is inflated with gas to increase volume, then the bed body expands to support the human body, but the waterproof cloth surface becomes hard and uncomfortable
Solution Approach 1:
The bed body is divided into two functional layers: the inflatable bed body (providing support) and the separate mattress (providing comfort). The mattress is constructed with multiple layers including a sponge layer that is segmented into independent pockets, allowing each layer to perform its specific function without interfering with the other.
Solution Approach 2:
The mattress combines multiple materials with different properties: waterproof cloth for the outer layers, sponge material for the comfort layer, and fabric for the pillow. This composite structure allows the hard inflatable bed body to be covered by a soft, comfortable mattress made of different materials that provide tactile comfort.
2Strength
If the waterproof cloth is stretched during inflation, then the bed body expands, but the surface becomes hard and uncomfortable
Solution Approach 1:
The mattress is divided into multiple functional layers (waterproof cloth layers and sponge layer) with the sponge layer segmented into independent pockets. This segmentation allows the structural integrity to be maintained by the inflatable bed body while the comfort function is provided by the separate, softer sponge layers that do not stretch during inflation.
3Volume of moving object
If the bed body is made compact for storage, then portability is improved, but the comfort layer must be integrated into the compact form
Solution Approach 1:
The mattress is designed to be wrapped around and integrated with the inflatable bed body. When deflated, the mattress can be folded and stored within or alongside the compact bed body, achieving space-efficient storage while maintaining the separate comfort layers during use.
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 design enhances the softness and comfort of the inflatable bed by incorporating a sponge layer and exhaust holes, improving the stability and practicality of storage and use, while maintaining a compact and cost-effective structure.
Implementation Method 1
the mattress comprises a first cloth adhesion layer, a sponge layer and a second cloth adhesion layer in sequence from top to bottom
Implementation Method 2
the top panel, the bottom panel and the first side panel are enclosed to form a gas chamber, after the gas enters the gas chamber, the bed body is expanded
