Single-Use Inflatable Mattress with Sealed Chambers for Recyclability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable mattresses are cumbersome, expensive, and difficult to dispose of, with issues related to durability, recyclability, and environmental impact, making them unsuitable for single-use applications such as camping or emergency bedding.
Innovation Solution
A flexible sheet material-based inflatable mattress with permanently sealed chambers, allowing for efficient manufacturing and recycling, featuring one-way valves for non-destructive deflation and a design that minimizes material usage while maintaining comfort and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If conventional inflatable mattresses are made durable and reusable, then they can be used multiple times, but they become heavy, complex to manufacture, and difficult to dispose of
Solution Approach 1:
The patent applies the disposable principle by designing a single-use inflatable mattress made from thin, lightweight plastic film that is inexpensive to manufacture. The mattress is intended for one-time use only, eliminating the need for heavy-duty materials and complex construction required for reusable mattresses. After use, the entire mattress can be easily discarded or recycled as a single component.
2Ease of manufacture
If conventional inflatable mattresses are made inexpensive and low-quality, then they can be discarded after single use, but they contain mixed durable plastics that create waste problems
Solution Approach 1:
The patent applies homogeneity by constructing the entire mattress from a single type of plastic film material. This uniform composition eliminates the mixed plastic waste problem associated with conventional mattresses that use multiple materials (fabrics, foams, different plastics). The homogeneous structure makes the mattress easy to manufacture from a single material source and simplifies recycling or disposal processes.
3Reliability
If individually inflated chambers are provided to prevent total deflation on puncture, then reliability improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies segmentation by dividing the mattress into multiple separate inflatable chambers that are sealed from one another. This segmentation provides puncture resistance because a hole in one chamber does not cause deflation of other chambers. The chambers are created by sealing sections of the plastic film, forming independent air pockets that maintain reliability without requiring complex valve systems or control mechanisms.
4Ease of manufacture
If a single inflated chamber is used to simplify construction, then manufacturing is easier, but the mattress becomes substantial and heavy for transport
Solution Approach 1:
The patent applies flexible shells and thin films by constructing the mattress from thin plastic film that forms the chamber walls. This thin-film construction significantly reduces the weight and bulk of the mattress compared to traditional fabric and foam constructions. The flexible nature of the plastic film allows the mattress to be easily folded or rolled for compact transport while maintaining structural integrity when inflated.
