Inflatable Bed Air Permeability Design Using Segmented Mesh Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inflatable beds have surfaces made of PVC with poor air permeability, making it difficult for the human body to dissipate excess heat and moisture, which reduces comfort.
Innovation Solution
Incorporating a top cover with multiple air holes and a sponge pad between the bed body and top cover, along with support mechanisms and buffer assemblies, to enhance air permeability and comfort by allowing air to flow and dissipate heat and moisture effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surface of the bed body is made of PVC material, then corrosion resistance and service life are improved, but air permeability deteriorates
Solution Approach 1:
The top cover is segmented into multiple regions with different functions: the first air permeable section with first air holes for breathability, the second air permeable section with second air holes for lateral ventilation, and the connection section for structural integrity. This segmentation allows different parts of the bed to serve different purposes, resolving the contradiction between durability and air permeability.
Solution Approach 2:
Different sections of the top cover have different material properties and structures tailored to their specific functions. The first air permeable section uses a mesh or perforated structure for maximum breathability, while the connection section uses stronger material for structural support. This local differentiation allows the bed to have both durability and air permeability where needed.
2Object-generated harmful factors
If air holes are added to the top cover, then air permeability is improved, but structural strength deteriorates
Solution Approach 1:
The top cover uses a flexible membrane structure with integrated air holes that maintains structural integrity while allowing air passage. The connection section between the first and second air permeable sections acts as a reinforcing element that distributes stress, preventing the thin permeable sections from compromising overall strength.
Solution Approach 2:
The top cover combines different material properties in a composite structure: the first air permeable section uses a breathable mesh or perforated material, the second air permeable section uses a similar permeable material, and the connection section uses a stronger, more rigid material. This composite approach allows each section to optimize for its specific function while maintaining overall structural strength.
3Ease of operation
If a sponge pad is added between the bed body and top cover, then comfort is improved, but device complexity increases
Solution Approach 1:
The sponge pad acts as an intermediary layer between the rigid bed body and the top cover, providing comfort through its elastic properties. It mediates the interaction between the user's body and the bed structure, distributing pressure and adapting to body contours. This simple intermediary element significantly improves comfort without requiring complex mechanisms.
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 solution significantly improves air permeability, reduces pressure on the body, and enhances comfort by allowing air to efficiently remove excess heat and moisture, while also providing stability and elasticity to adapt to the human body shape.
Implementation Method 1
the sponge pad is provided between the bed body and the top cover... the air may flow from the first air holes of the top cover to the sponge pad and be discharged from the sponge pad, thus increasing the air permeability of the surface of the inflatable bed
Implementation Method 2
each of the plurality of support mechanisms includes a first buffer assembly and a second buffer assembly... the first elastic elements are connected to the buffer block... the second elastic element is located in the guide cylinder... the sponge pad also possesses a good air permeability, so that the person is less likely to sweat when sleeping, thereby improving the sleep quality

AI summary
An inflatable bed with air permeability includes a bed body including a top panel, an enclosing wall and a bottom panel, a top cover, a first pull strap, and a second pull strap which are both endless. A top side of the first pull strap is connected to an inner wall of the top panel, and a bottom side of the first pull strap is connected to an inner side wall of the enclosing wall. A bottom side of the second pull strap is connected to an inner wall of the bottom panel, and a top side of the second pull strap is connected to the inner side wall of the enclosing wall. The first net-shaped pull strap includes two first air permeable sections parallel to each other, two second net-shaped air permeable sections parallel to each other and four connection sections distributed in a rectangular array.
