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 structure becomes complex and costly with additional components
Solution Approach 1:
The patent uses a flexible cylindrical tube made of elastic material instead of a rigid tube with complex support structures. The flexibility of the tube allows it to deform during winding and packaging operations, eliminating the need for rigid support pipes, coupling rings, and complex mechanical assemblies while still achieving uniform winding of the wallpaper.
Solution Approach 2:
The patent changes the physical state of the cylindrical tube from rigid to flexible by using elastic material. This parameter change allows the tube to be compressed flat for packaging and then inflated back to its cylindrical shape for winding, simplifying the overall structure while maintaining the ability to wind wallpaper uniformly.
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 and labor-intensive
Solution Approach 1:
The flexible tube eliminates the need for complex mechanical components such as support pipes, coupling rings, and transmission gears. The tube can be manually manipulated and inflated, significantly simplifying the assembly and operation process while still achieving uniform winding through its elastic properties.
Solution Approach 2:
The flexible tube serves multiple functions: it acts as the winding core, provides structural support during inflation, and can be manually manipulated for packaging. This self-service approach eliminates the need for multiple specialized components and complex operational procedures.
3Device complexity
If narrow tubes with limited height are used for packaging, then the packaging structure is simple, but the wallpaper has many seams that come off and become loose over time
Solution Approach 1:
The patent transitions from narrow vertical tubes to a flat packaged configuration where the wallpaper is compressed horizontally. This dimensional change allows the wallpaper to be packaged in a flat state that maintains seam integrity while still providing cylindrical winding during installation. The tube can be inflated to its full cylindrical shape during installation, providing the necessary height for seam stability.
4Reliability
If additional packaging components and protective measures are added, then the wallpaper is better protected during transportation, but the cost and labor requirements increase
Solution Approach 1:
The flexible tube serves as both the winding structure and the protective packaging. When compressed flat, the tube itself becomes the protective container for the wallpaper, eliminating the need for separate packaging components. The tube can be sealed and transported in its flat state, then inflated during installation, providing protection without additional cost or labor.

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.
