Waved Mesh Tube Structure for Higher Rigidity and Skin Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mesh tubes used for making bath balls or brushes are too soft, lack rigidity, and have a smooth surface, making them ineffective for providing a rubbing effect on aged skin, and they have a unified thin diameter which results in a non-compact and inefficient design.
Innovation Solution
A mesh tube with a waved, solid, and thicker wall structure is created by extruding parallel strings at higher temperatures to form continuous circles of waved bending sections, resulting in a significant difference between the inner and outer diameters, providing increased thickness and rigidity, and a rougher surface with acute angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mesh tube is made with thin walls and unified diameter, then the manufacturing is easier and material usage is reduced, but the rigidity and compactness are insufficient
Solution Approach 1:
The mesh tube is transformed from a straight cylindrical shape to a waved shape with continuous bending sections. This curvature modification increases the rigidity and structural integrity of the thin-walled tube without requiring additional material or changing the basic manufacturing process.
Solution Approach 2:
The patent changes the geometric parameters of the mesh tube by introducing wave patterns with specific wavelengths and amplitudes. This transforms the uniform cylindrical structure into a waved structure that provides enhanced rigidity while maintaining the same material composition and manufacturing method.
2Ease of manufacture
If the mesh tube has a smooth surface, then the manufacturing process is simpler, but the rubbing effect on skin is insufficient for removing dead skin cells
Solution Approach 1:
The waved bending sections create an inherently rough surface topology that provides mechanical exfoliation effect. The continuous waves form peaks and valleys that naturally create friction and rubbing action against the skin during use, eliminating the need for additional surface texturing processes.
3Quantity of substance
If the mesh tube wall is made thinner to reduce material usage, then the cost is reduced, but the compactness and solid structure are compromised
Solution Approach 1:
The waved structure creates a more compact three-dimensional form factor. The continuous bending sections allow the tube to occupy less space while maintaining structural integrity, effectively increasing the density and compactness of the thin-walled structure without requiring additional material.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The waved mesh tube offers higher rigidity and a better rubbing effect on the skin, making it more effective for removing dead skin cells while being more compact and solid compared to conventional designs.
Implementation Method 1
The mesh tube is extruded by a specific equipment at a temperature higher than room temperature and formed with a waved pattern.

AI summary
A waved mesh tube including multiple parallel first strings spirally extending in a first direction and multiple parallel second strings spirally extending in a second direction. The second strings are laid on the first strings. The mesh tube has continuous circles of waved bending sections arranged along an axis of the mesh tube. The mesh tube is formed with the bending sections so that the wall of the mesh tube has multiple wave crests and wave troughs adjoining each other. The wave troughs define an inner diameter of the mesh tube, while the wave crests define an outer diameter of the mesh tube. Each of the wave crests and the wave troughs has an acute angle. A difference between the inner diameter and the outer diameter is a thickness of the wall of the mesh tube. The wall of the mesh tube is waved and solid and has higher rigidity.
