Rotating Spool Guide for Embroidery Material Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sewing machines lack an efficient mechanism for seamlessly integrating and dispensing various embroidery materials, such as ribbon or cord, onto a workpiece while maintaining the machine's operational stability and versatility.
Innovation Solution
A sewing machine accessory featuring a stationary support and a rotating support with a spool mechanism that dispenses embroidery material, guided by adjustable sewing guides to accommodate different materials, ensuring the needle follows a predetermined path for precise stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spool mechanism with rotating support is added to dispense embroidery material, then the versatility of embroidery materials is improved, but the device complexity increases
Solution Approach 1:
The accessory assembly serves multiple functions: the spool mechanism dispenses various embroidery materials (ribbon, cord, etc.), the rotating support positions the material, and the sewing guide directs the material along the needle path. This multi-functional design enables the sewing machine to handle diverse embroidery materials without requiring separate devices for each material type.
Solution Approach 2:
The accessory is divided into separable components: a removable sewing guide and a fixed accessory assembly. The sewing guide can be detached and replaced to accommodate different embroidery material types, while the main accessory assembly with spool and rotating support remains. This segmentation allows flexibility in adapting to different materials without replacing the entire accessory system.
2Adaptability or versatility
If a removable sewing guide is used to accommodate different embroidery materials, then the adaptability is improved, but the ease of operation deteriorates due to additional attachment and removal steps
Solution Approach 1:
The sewing guide is designed with dynamic attachment and detachment capabilities, allowing it to be easily removed and reattached during operation. The guide can be quickly detached to swap between different material types and reattached without complex procedures, maintaining operational flexibility while minimizing interruption to the embroidery process.
3Manufacturing precision
If the rotating support rotates to lead the embroidery material along the sewing path, then the precision of material placement is improved, but the device complexity increases
Solution Approach 1:
The rotation mechanism is integrated into the existing accessory assembly rather than being a separate complex subsystem. The rotating support combines the spool mounting, material guidance, and rotational movement functions in a single compact structure, achieving precise material placement along the sewing path without requiring an overly complex mechanism.

AI summary
An exemplary embroidery accessory for a sewing machine includes a stationary support attached to the sewing machine and a rotating support rotatably attached to the stationary support. A drive mechanism rotates the rotating support relative to the stationary support and a spool supported by the rotating support receives and dispenses a length of embroidery material. The removable guide is removably attached to the rotating support and includes a sewing guide with a needle opening for receiving a needle of the sewing machine, and at least one guide for guiding the length of embroidery material from the spool to the sewing guide.
