Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn feeders are space-consuming due to the indirect drive mechanism involving a driving motor, belt member, and winding wheel, making them inefficient in factory space arrangement when multiple units are required.
Innovation Solution
A compact yarn feeder design featuring a metric-sized motor with a drive shaft connecting to a rotating member, screw rods for secure mounting, and a tube-shaped winding wheel with elastic strips for secure yarn roll placement, allowing direct motor-driven winding with reduced volume and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional yarn feeder uses a driving motor connected to a winding wheel through a belt member, then the winding function is achieved, but the device occupies excessive factory space
Solution Approach 1:
The motor and winding wheel are merged into a single integrated assembly where the motor shaft directly drives the winding wheel, eliminating the need for separate belt transmission components. This consolidation reduces the overall device volume and simplifies the structure while maintaining the winding function.
Solution Approach 2:
The belt transmission component is extracted and removed from the system. By eliminating this intermediate transmission element, the design achieves direct motor-to-winding-wheel drive, significantly reducing the space required for the device.
2Productivity
If multiple yarn feeders are deployed for yarn winding, then production capacity increases, but space arrangement becomes severely constrained
Solution Approach 1:
Multiple yarn feeders can be closely arranged or even stacked due to the compact integrated motor-winding wheel design. The reduced footprint of each unit allows higher density deployment in the factory, enabling increased productivity without proportional increase in space occupation.
3Ease of manufacture
If a conventional yarn feeder uses separate components for motor mounting and winding, then assembly is flexible, but manufacturing cost increases
Solution Approach 1:
The motor mounting structure and winding wheel structure are merged into a single integrated component. This eliminates the need for separate mounting brackets, belt guards, and alignment mechanisms, thereby reducing part count, simplifying manufacturing processes, and lowering overall production costs.
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 design reduces the overall volume and manufacturing costs of the yarn feeder while ensuring efficient yarn winding and secure roll placement, addressing space constraints and cost inefficiencies of conventional systems.
Implementation Method 1
a plurality of arc-shaped elastic strips are arranged around the winding wheel, and each of the elastic strips has two ends respectively connected to the two ring bodies. Thus, when a yarn roll is disposed on the winding wheel, the elastic strips are configured to abut against an inner periphery of the yarn roll

AI summary
A yarn feeder may comprise a metric-sized motor and a winding wheel, and a drive shaft axially protruding from a first end of the motor is configured to connect to a rotating member. The winding wheel formed in a tube shape comprises a first end and a second end, and an interior channel is adapted to axially penetrate through the winding wheel from the first end to the second end thereof. The interior channel is configured to accommodate the motor, and the rotating member is coupled with the interior channel such that the motor is configured to drive the winding wheel through the rotating member. The motor in the present invention is a metric-sized motor which is not only easy to buy in the market but also reduces manufacturing cost and the volume of the yarn feeder.
