Dual-Use Tent Structure With Inflatable Cushion for Land and Water Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cushion beds and tents are not moisture-proof and lack wind resistance, limiting their use in rainy conditions and on water surfaces, and are not designed for integrated use on both land and water.
Innovation Solution
A dual-purpose tent with an inflatable cushion body and tent main body, featuring a tent bracket, bottom support edge, fixing strap, and sunshade canopy, along with a foldable bracket for automatic inflation and unfolding, and a windproof-and-rainproof outer tent body for enhanced stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the air cushion is directly in contact with the ground, then the structure is simple and easy to set up, but it cannot be moisture-proof and cannot be used in rainy days
Solution Approach 1:
A waterproof groundsheet is introduced as an intermediary layer between the air cushion and the ground. The groundsheet prevents direct contact between the air cushion and moisture source, providing moisture-proof protection while maintaining the simplicity of the air cushion structure itself
2Reliability
If waterproof fabrics are used for the tent, then moisture-proof performance is improved, but wind resistance is limited
Solution Approach 1:
The tent employs a composite structure combining waterproof fabric for the inner tent with a separate outer tent layer. This layered composite design allows the inner layer to provide moisture-proof protection while the outer layer enhances wind resistance, with both layers working together to address both requirements simultaneously
3Ease of manufacture
If the tent and air cushion bed are separated, then each component can be optimized independently, but they cannot be fixed on a water surface and overall flatness and use safety are affected
Solution Approach 1:
The tent and air cushion bed are merged into an integrated system through connecting structures. The air cushion bed is positioned within or connected to the tent structure, allowing them to function as a unified unit that can be stabilized on water surfaces while maintaining the ability to optimize each component's design independently
4Ease of operation
If a foldable bracket is used for automatic unfolding, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The foldable bracket incorporates a self-service mechanism where the inflation of the air cushion automatically triggers the unfolding of the bracket structure. The expanding air cushion provides the mechanical force needed to drive the bracket from folded to unfolded position, eliminating the need for separate manual or powered unfolding mechanisms

Function Achieved in This Case
The tent provides moisture-proofing, wind resistance, and stability on both land and water, ensuring comfort and practicality with dual-use capabilities and easy portability.
Implementation Method 1
the buoyancy of the inflatable cushion body can be used on the water surface through the inflatable cushion body

AI summary
A dual-purpose tent suitable for both water and land is provided, which includes a tent main body and an inflatable cushion body. The tent main body includes a tent bracket, a tent body, and a bottom support edge; the bottom support edge is fixed at a bottom of the tent body; the tent body and bottom support edge are fixed on the tent bracket; a fixing strap is provided in the bottom support edge; the inflatable cushion body is located in the tent body, and an edge of the inflatable cushion body is attached to an inner side of the bottom support edge and fixed with the fixing strap. The structure of the dual-purpose tent is reasonably, the inflatable cushion body is provided in the tent. The inflatable cushion can still maintain comfort in places with small stones and tree stumps and is also conducive to improving dehumidification performance.
