Solution Overview
Problem
Existing methods for winding and packaging wide wallpaper are inconvenient, complex, and costly, leading to issues such as seams, damage, and increased labor and financial costs during transportation and installation.
Innovation Solution
The use of a flexible cylindrical tube with a valve for winding and packaging wide wallpaper, allowing air to be pumped in to form a cylindrical shape, followed by releasing air to create a flat structure for easy packaging and storage, using materials like vinyl, PVC, or polyethylene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid cylindrical tube is used for winding wallpaper, then the wallpaper can be wound uniformly, but the device becomes complex and difficult to assemble
Solution Approach 1:
The patent uses a flexible cylindrical tube made of flexible material instead of a rigid tube. This flexible tube can be easily formed into a cylinder and maintains its shape during the winding process, achieving uniform winding without requiring complex rigid structural components. The flexible material allows the tube to be simply assembled and disassembled.
Solution Approach 2:
The patent employs air pumping into the flexible cylindrical tube to maintain its cylindrical shape during the winding process. The air pressure keeps the tube rigid enough to support uniform winding, while allowing for easy assembly and disassembly. After winding, the air is released and the tube is flattened for compact packaging.
2Manufacturing precision
If a complex winding device with multiple mechanical parts is used, then the wallpaper can be wound uniformly, but the assembly and operation process becomes complex
Solution Approach 1:
The flexible cylindrical tube requires no complex mechanical parts for assembly. It is simply a flexible tube that is formed into a cylinder, filled with air, and then the wallpaper is wound on it. The tube is easily disassembled by releasing air and flattening it, making the entire process simple and efficient.
Solution Approach 2:
The patent extracts the complex mechanical structure from the winding device, leaving only the essential flexible cylindrical tube. The uniform winding is achieved through the simplicity of the tube structure combined with air pressure, eliminating the need for multiple mechanical components and complex assembly procedures.
3Reliability
If traditional packaging methods are used, then the wallpaper can be transported, but the process requires additional labor and financial costs
Solution Approach 1:
The flexible cylindrical tube can be dynamically transformed between a cylindrical shape (for winding and transportation) and a flattened shape (for compact packaging). This dynamic transformation allows the same structure to serve both transportation and storage functions, eliminating the need for separate packaging materials and reducing labor costs.
Solution Approach 2:
The flattened flexible tube can be nested within itself or placed compactly in containers for storage and transportation. The tube maintains its structural integrity when flattened, allowing for efficient use of space in packaging while remaining ready for easy deployment to the destination.
4Ease of manufacture
If narrow wallpaper rolls are used, then the packaging is simple, but the number of seams increases and the overall picture is spoiled
Solution Approach 1:
The patent transitions from narrow wallpaper rolls to wide wallpaper by changing the dimensional perspective. The flexible cylindrical tube can accommodate wide wallpaper in a single continuous roll, eliminating the need for multiple narrow rolls and their corresponding seams. The tube structure allows the wide wallpaper to be wound uniformly in one piece, achieving a seamless appearance.

AI summary
The invention relates to a method of winding and packaging wide wallpaper, which is wound around a roll on a winding and rotary device, followed by packaging wallpaper in containers for transportation or storage. In the first embodiment of the invention, in the presented process, winding of the wallpaper (3) is carried out onto a winding and rotation mechanism, made in the form of a finished hollow closed cylindrical tube (1) of flexible material, equipped with a valve (2) for supplying and discharging air from it. At the same time, the valve (2) is fixed on one of the tube bases (4). Along the length of the pumped cylindrical tube (1) is fixed the edge of the wallpaper (3) and wound it on the tube (1) until a roll of the required length is obtained. In the second embodiment of the invention, the tube for wallpaper winding is formed from a part of a whole piece of wallpaper material (6) separated from the edge (7) in the form of a fold along the width of the wallpaper. The selected part of the wallpaper material, corresponding to the diameter of the tube (9) being created, is laid in width in two layers and fastened along the perimeter of the formed sides. The valve (10) is installed on one of the bases of the cylindrical tube (9) formed when air is pumped. The rest of the whole piece of wallpaper is wound on the tube (9) until a roll of the required length is obtained. Further, in both embodiments of the described method, the air is released from the tube through the valve to form a flat rectangular structure in the form of wallpaper layers with a tube placed inside. The resulting structure is laid into several layers for packaging in containers and subsequent storage and transportation. Flexible materials such as paper, vinyl, PVC, polyethylene and others are used as material for the manufacture of the tube.
