Solution Overview
Problem
Higher spindle speeds in ring spinning machines lead to increased risks of thread breakage due to enlarged thread balloons and centrifugal forces, and conventional balloon constriction rings cause high friction and damage to the yarn.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spindle speed is increased to enhance productivity, then productivity is improved, but the risk of yarn breakage increases due to enlarged yarn balloon and centrifugal forces
Solution Approach 1:
The patent replaces the conventional mechanical ring traveler system with a magnetic field-based floating spinning ring system. The spinning ring is suspended by a magnetic field generated by a nitrogen-cooled superconductor, eliminating mechanical contact and friction. This substitution enables operation at significantly higher spindle speeds without the mechanical constraints that previously limited speed and caused yarn breakage, thus resolving the contradiction between productivity and reliability.
Solution Approach 2:
The patent fundamentally changes the operational parameters by removing the ring traveler system that imposed mechanical friction limits. The floating spinning ring operated in a magnetic field allows spindle speeds to increase from conventional limits to over 10,000 rpm, while the magnetic suspension maintains stability and prevents yarn breakage even at these elevated speeds, effectively changing the speed parameter range without sacrificing reliability.
2Stability of the object's composition
If conventional balloon constriction rings are used to limit yarn balloon, then yarn balloon is controlled, but high frictional forces damage both the constriction ring and the yarn
Solution Approach 1:
The patent eliminates the mechanical balloon constriction ring system entirely and replaces it with a magnetic field-based floating spinning ring that controls yarn balloon without physical contact. The magnetic suspension and floating ring design provide yarn support and balloon control through magnetic forces rather than mechanical friction, preventing damage to both the constriction device and the yarn while maintaining effective balloon limitation.
3Ease of operation
If ring traveler system is used for yarn guidance, then yarn guidance is provided, but friction limits the maximum spindle speed
Solution Approach 1:
The patent replaces the mechanical ring traveler guidance system with a floating spinning ring suspended by a magnetic field. The spinning ring is driven by magnetic coupling rather than mechanical contact, eliminating the friction between the traveler and yarn that previously limited spindle speed. This substitution maintains effective yarn guidance functionality while enabling operation at significantly higher speeds without the mechanical friction constraints.
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
Enables reliable high-speed spinning without thread breakage, maintaining proper winding tension and preventing yarn damage, thus enhancing productivity and efficiency.
Implementation Method 1
a spinning ring guide unit arranged coaxially with the spindle axis, wherein the spinning ring is fixed to the spinning ring guide unit in a floating manner in the spindle axis direction
Implementation Method 2
EP 3 231 904 A1 discloses the use of a nitrogen-cooled superconductor. Due to the suspended and thus contactless mounting of the spinning ring
Implementation Method 3
the yarn is guided along the inner side of the balloon limiter sleeve. Unlike conventional spinning devices, the spinning device according to the invention dispenses with a ring traveler system; the yarn is guided past the spinning ring on the outside
Implementation Method 4
the higher spindle speeds also result in increased centrifugal forces acting on the yarn
