Solution Overview

Problem

Metal chains used for lifting heavy loads are heavy, susceptible to wear and tear, and prone to rusting, complicating transportation and posing safety risks due to visible fiber breakage when worn.

Innovation Solution

A Möbius strip forming device and textile chain forming machine that uses a textile strip to create links with exceptional wear and load capacity, utilizing a rotation module, gas injectors, and a textile chain forming procedure to form a chain where each link is a Möbius strip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metal chains are used for lifting heavy loads, then load capacity is achieved, but weight increases and wear resistance deteriorates

Engineering Contradiction:
Improveload capacityVSAvoidchain weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent changes the material parameter from metal to textile fiber, fundamentally altering the physical properties of the chain. This allows the chain to be much lighter while maintaining load capacity through the specific Möbius strip configuration that optimizes stress distribution across the fiber structure.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite construction by forming the chain from multiple textile fibers woven into a Möbius strip configuration. This composite approach combines the strength of synthetic fibers with the geometric advantage of the Möbius topology to achieve both light weight and high load capacity.

Inventive Principle:
Principle #40Composite materials

2Strength

If metal chains are used for lifting heavy loads, then load capacity is achieved, but durability deteriorates due to rust and wear

Engineering Contradiction:

3Weight of moving object

If traditional fiber tapes are used instead of metal chains, then weight is reduced, but structural integrity deteriorates without proper forming

Engineering Contradiction:
Improvechain weightVSAvoidstructural integrity
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent applies the Möbius strip geometric form, which is a continuous curved surface with unique topological properties. This curvature and torsion in the fiber arrangement distributes mechanical stresses more evenly throughout the structure, preventing stress concentration and improving overall structural integrity while maintaining lightweight characteristics.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent changes the material parameter from metal to textile fiber, fundamentally altering the physical properties of the chain. This allows the chain to be much lighter while maintaining load capacity through the specific Möbius strip configuration that optimizes stress distribution across the fiber structure.

Inventive Principle:
Principle #35Parameter changes
