Magnetic Winding Disc Holding for Torque-Resistant Wire Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices face challenges in preventing the rotation of the winding disk due to torques and forces applied during the winding process, particularly when using horizontally arranged disks, as conventional bearing systems fail to effectively absorb torques about the vertical axis, leading to potential rotation of the disk.
Innovation Solution
A magnetic holding device is employed, comprising two magnetic arrangements with opposing poles and a gap through which the winding material passes, utilizing a configuration of permanent magnets and soft iron blocks to create a strong holding force that prevents the winding disk from rotating, with the magnetic field lines aligned to maximize the holding force and minimize diverging field contributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a horizontally arranged winding disk is used, then the winding device can effectively store and process strand-shaped material, but the winding disk rotates due to torques applied during winding
Solution Approach 1:
The patent replaces the conventional mechanical bearing system with a magnetic field-based holding device. Permanent magnets arranged in alternating polarity patterns create magnetic forces that counteract the torques applied during winding, preventing disk rotation without mechanical contact. This substitution resolves the contradiction by providing torque resistance through magnetic fields rather than mechanical bearings.
Solution Approach 2:
The patent changes the physical state from mechanical support to magnetic field interaction. By arranging permanent magnets with alternating polarities (north-south-north-south pattern), the system creates localized magnetic holding zones that dynamically counteract applied torques. This parameter change in the support mechanism enables the disk to remain stationary during winding operations.
2Force
If conventional bearing systems are used to support the winding disk, then mechanical support is provided, but they fail to absorb torques about the vertical axis
Solution Approach 1:
The patent replaces mechanical bearings with a magnetic field-based holding device. Permanent magnets arranged in alternating polarity patterns create magnetic forces that counteract the torques applied during winding, preventing disk rotation without mechanical contact. This substitution resolves the contradiction by providing torque resistance through magnetic fields rather than mechanical bearings.
3Stability of the object's composition
If the winding disk is prevented from rotating, then stationary winding is achieved, but the system requires additional magnetic holding devices
Solution Approach 1:
The magnetic holding device is segmented into multiple permanent magnets arranged in alternating polarity patterns around the circumference of the winding disk. This segmentation allows each magnet pair to independently contribute to torque resistance, distributing the stabilizing function across multiple locations rather than requiring a single complex mechanism.
Solution Approach 2:
The alternating polarity magnet arrangement serves multiple functions simultaneously: it creates holding forces to prevent radial displacement, generates torque resistance against rotational forces, and provides uniform magnetic field distribution. This multi-functionality reduces the need for additional separate components.

Function Achieved in This Case
The magnetic holding device effectively prevents the winding disk from rotating by generating a high holding force that counteracts torques and forces, ensuring the disk remains stationary, even under stronger torques, and allows for precise centering and adjustment of the winding disk.

AI summary
The invention relates to a winding device for winding strand-like material to be wound (8), for example wire, having a winding disc (1) onto which the strand-like material to be wound (8) is wound up, and a housing arranged adjacently to the winding disc (1). The winding disc (1) is prevented from moving, in particular rotating, by at least one magnetic holding device (2), wherein the magnetic holding device (2) has a first magnetic arrangement (5) connected to the housing for conjoint rotation and a second magnetic arrangement (6) connected to the winding disc (1) for conjoint rotation, each magnetic arrangement having a north pole N and a south pole S. Between the first magnetic arrangement (5) and the second magnetic arrangement (6) there is a gap (4), and the first magnetic arrangement (5) and the second magnetic arrangement (6) are magnetically coupled across the gap (4), wherein the strand-like material to be wound (8) is guided through the gap (4). In this case, the two magnetic arrangements (5, 6) are arranged such that the south pole S of the first magnetic arrangement (5) is located opposite the north pole N of the second magnetic arrangement (6) and the north pole N of the first magnetic arrangement (5) is located opposite the south pole S of the second magnetic arrangement (6), with the result that particularly high holding forces are achievable. Preferably, the first magnetic arrangement (5) and/or the second magnetic arrangement (6) are formed in a horseshoe-shaped manner.
