Möbius Strip Textile Chain Forming for High Load and Low Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal chains used for lifting and securing heavy loads are heavy, prone to wear and tear, and susceptible to rust, making them inefficient and potentially hazardous for use in transporting goods.
Innovation Solution
A textile chain forming machine that uses a Möbius strip forming device to create links in the shape of Möbius strips from textile strips, which are then assembled into a chain with exceptional wear resistance and high load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal chains are used for lifting and securing heavy loads, then high strength and load capacity are achieved, but the chains become very heavy and add additional load to the cranes
Solution Approach 1:
The invention changes the material parameter from metal to textile fibers, fundamentally altering the weight-to-strength ratio. Textile chains made from high-strength fibers achieve comparable load capacity to metal chains while weighing significantly less, directly resolving the contradiction between strength and weight
Solution Approach 2:
The textile chain is constructed as a composite structure with multiple fiber strands twisted together to form ropes, which are then configured into link shapes. This composite approach allows the chain to achieve metal-like strength through the combined effect of multiple fibers while maintaining the inherent lightness of textile materials
2Strength
If metal chains are used for transporting goods, then high load capacity is achieved, but they are very susceptible to wear and tear and rust
Solution Approach 1:
The invention changes the material composition from metal to textile fibers, fundamentally altering the wear and corrosion characteristics. Textile fibers do not rust and exhibit superior wear resistance, directly resolving the reliability issue while maintaining load capacity through proper fiber selection and chain construction
Solution Approach 2:
The textile chain is designed with replaceable sections and modular construction, allowing worn components to be replaced rather than the entire chain. This approach acknowledges that while textile chains have excellent wear resistance, they are still subject to wear and can be economically replaced rather than maintained like metal chains
3Weight of moving object
If traditional chain links are formed from textile strips, then the chain can be made lighter, but the links lack the structural integrity to withstand very high loads
Solution Approach 1:
The invention forms the textile strip into a Möbius strip configuration, which creates a continuous twisted loop structure. This curved, three-dimensional form distributes mechanical stresses more evenly throughout the link compared to flat or simple loop configurations, significantly enhancing the structural integrity and load-bearing capacity of each link while maintaining the light weight advantage of textile materials

AI summary
A forming device for forming links in the shape of a Möbius strip includes a rotation module with an inner path. The forming device has a widening for 180° rotation of a strip introduced into the rotation module. The rotation module has an inlet suitable for one end of a strip, an outlet suitable for the strip and the inner path extends from the inlet to the outlet. The widening is adapted for rotation of the end of the strip 180° about its longitudinal axis. The device also includes a gas injector positioned at the inlet of the rotation module intended to drive the strip through the inner path of the rotation module.
