What it does
The product revolutionizes rescue operations by addressing portability, operation complexity, and limited scenarios in traditional models. Its reusable system uses minimal gas for rapid deformation, generating crucial support force to fill debris gaps.
Your inspiration
Pneumatic rescue airbags provide lightweight, low-power support advantages over traditional machinery. However, conventional full-bag inflation/deflation processes are slow, creating efficiency bottlenecks in emergencies. The linear origami structure drives spatial changes through the extension and contraction of mountain and valley line frameworks. The innovative "line-driven body" concept inspired by origami design offers new possibilities for rescue equipment development, enabling rapid deployment and retraction of airbags via origami structures. This approach enhances rescue efficiency while improving equipment portability.
How it works
the air pump is responsible for rapid inflation to quickly unfold the folded airbag; the high-pressure gas cylinder drives the airbag to expand and contract vertically, achieving the lifting and supporting function. It innovatively adopts a linear folding air circuit instead of the traditional full-volume inflation method: after inflation, the air circuit forms a rigid diamond-shaped "skeletal" structure, generating a regular and uniform expansion effect inside the airbag. Through pre-designed pneumatic paths consisting of mountain lines and valley lines formed by folding lines, it realizes the innovative folding pneumatic deformation strategy of "driving the whole body with lines". When the folded space is rapidly deformed under the drive of the linear air circuit, the one-way valve automatically inhales air from the outside by utilizing the gas pressure difference, greatly improving the inflation efficiency.
Design process
1.Fold Structure Design and Optimization To address traditional pneumatic circuit routing issues such as complex bends and crease flow resistance, fluid simulation was employed to redesign the path. The complex circuit was simplified into a combination of straight lines and curves, with optimized gas distribution layout. 2. Surface Contour Control Linear pneumatic hinges employ heat-sealed TPU welding. The "fold crease" disturbance effect generated by hot pressing enables material bending. Material flipping allows flexible control of both mountain line and valley line folding. 3.Bend Morphology Optimization Through multiple experimental verifications, the valley line pneumatic diamond hinge was modified to a linear series of four diamond designs, balancing folding performance and ventilation efficiency. Mountain lines retain single-line welding while relying on valley line contour deformation. An innovative dual-diamond symmetrical layout controls bend contour morphology. 4.System Simulation Verification Combining Rhino high-precision modeling with Abaqus multiphysics coupled simulation: The former analyzes structural deformation patterns and establishes mathematical models, while the latter simulates full-process morphological transitions.
How it is different
1.Based on the folding structure, the pneumatic rescue products for rescuing trapped people in different situations are designed and used together to meet the product requirements of safety, portability and strong applicability. 2.The deformation design idea of "line leading body" is put forward. The folding structure line is designed as a linear air path, and the deformation direction is precisely controlled by the rhombic hinge structure, so as to achieve the maximum reduction of inflation volume and inflation time. 3.The air path crease path is optimized, and the automatic folding along the crease line can be realized during exhaust to improve the storage efficiency.
Future plans
The plan aims to further expand the application of pneumatic folding technology in rescue operations, developing inclined force jacks and specialized channels. Leveraging the core advantages of pneumatic folding—such as rapid deployment, portability, and efficiency—we will design innovative structures and functionalities tailored to diverse rescue scenarios (including natural disasters and accident sites). This initiative seeks to create a series of lightweight, modular rescue equipment that enhances emergency response capabilities and improves overall rescue efficiency.
