Foldable Modular Baby Bedding with Dust-Sealed Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beddings for babies and infants are not suitable for easy rearrangement or carrying due to low flexibility in structure, discomfort when folded, and poor sealing that allows dust entry.
Innovation Solution
A bedding system comprising two coupled mattresses with removably mounted wall-surface cushion materials and handles, using coupling members like zippers or hook-and-loop fasteners for flexibility and sealing, allowing the bedding to be easily folded and rearranged while preventing dust entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wall-surface units are coupled to the mattress to form a box-shaped body, then the bedding provides structural stability and support, but the degree of freedom in rearrangement corresponding to specific purpose of use is low
Solution Approach 1:
The bedding is divided into separate modular components: mattresses, wall-surface cushion materials, and coupling members. The wall-surface cushion materials can be removably mounted on the mattresses using coupling members, allowing the structure to be segmented and reconfigured for different uses while maintaining stability when assembled.
2Ease of operation
If an elastic body such as EVA foam is used for the mattress and wall-surface units to enable folding into a compact bag, then the bedding becomes portable, but the comfort is reduced due to the thin and soft nature of the elastic body
Solution Approach 1:
The bedding uses composite construction with mattresses and wall-surface cushion materials that can be folded for portability, while coupling members and reinforcing structures maintain the necessary support and comfort. The system combines foldable elements with structural components that preserve reliability when assembled for use.
3Ease of operation
If the bedding is formed into a compact bag by folding the mattress and wall-surface units, then the bedding becomes convenient to carry around, but dust easily enters the compact bag due to many gaps
Solution Approach 1:
The bedding incorporates a reinforcing cloth that forms a shell-like structure around the mattresses and cushion materials. When folded into a compact bag, this flexible shell encloses the components and prevents dust from entering through gaps, while still allowing the bedding to be compressed for portable storage.
4Stability of the object's composition
If the frame body is coupled to the reinforcing cloth to provide structural support, then the bedding maintains its shape, but the degree of freedom in rearrangement is low and a separately placed mattress is needed
Solution Approach 1:
The structural support function is separated from the mattress component. The reinforcing cloth provides the frame structure, while mattresses and wall-surface cushion materials are separate removable elements that can be configured differently. This segmentation allows shape maintenance through the reinforcing cloth while enabling flexible rearrangement of the cushion components for different uses.
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 provides high flexibility in use, comfort without needing a separate mattress, and effective sealing to prevent dust entry when carried or stored.
Implementation Method 1
using coupling members like zippers or hook-and-loop fasteners for flexibility and sealing
Implementation Method 2
The handles removably mounted on both the mattresses or the wall-surface cushion materials. The bedding for babies and infants is configured to be carried around with the handles
Implementation Method 3
both the mattresses are folded such that top surfaces of corresponding wall-surface cushion materials are abutted to be closed with a coupling member

AI summary
A bedding for babies and infants includes two mattresses, wall-surface cushion materials, and handles. The two mattresses have mutually opposite sides that are coupled and have square shapes in planar views of the two mattresses. The wall-surface cushion materials are removably mounted on top surfaces of other three sides excluding the coupled sides of both the mattresses via coupling members. The handles removably mounted on both the mattresses or the wall-surface cushion materials. The wall-surface cushion materials are separably and mutually coupled between the adjacent wall-surface cushion materials via coupling members. The bedding for babies and infants is configured to be carried around with the handles in a state where both the mattresses are folded such that top surfaces of corresponding wall-surface cushion materials are abutted to be closed with a coupling member.
