Computerized Sewing Machine Stitch Pattern Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sewing methods for creating embellishments, such as appliqué, ribbon, and pop-up designs, are time-consuming and lack precision, as they require manual stitching and are limited by the capabilities of traditional presser feet, making it difficult to reproduce designs accurately and efficiently.
Innovation Solution
A computerized sewing machine system with a processor and user interface that allows operators to input stitch patterns and execute commands to sew specific portions of a design, including stop commands to manage the sewing process, enabling precise and accurate replication of embellishments without the need for manual removal of excess fabric or limited presser foot guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual stitching methods are used for creating embellishments, then flexibility in design creation is maintained, but time consumption increases and precision decreases
Solution Approach 1:
The patent replaces manual mechanical stitching with an automated computerized sewing machine system that executes pre-programmed stitch patterns. The processor controls the needle movement, stitch formation, and automated needle threader mechanism, eliminating manual dexterity requirements while maintaining design precision and reducing time consumption.
Solution Approach 2:
The system allows operators to input and store stitch patterns in advance through the user interface. The processor executes these pre-programmed patterns automatically, enabling repetitive embellishments to be created without重新 programming. The automated needle threader is also pre-configured to thread the needle without manual intervention.
2Adaptability or versatility
If traditional presser feet are used for ribbon application, then simple straight or zigzag stitches are achieved, but design versatility is limited
Solution Approach 1:
The computerized sewing machine system provides universal stitch pattern capabilities through the processor and user interface, replacing the need for multiple specialized presser feet. The system can execute various stitch patterns including straight stitches, zigzag stitches, and decorative patterns, all controlled programmatically without changing physical presser foot components.
Solution Approach 2:
The patent replaces mechanical presser foot guidance systems with computerized control through the processor. The user interface allows selection of different stitch patterns, and the processor automatically controls needle movement and stitch formation, eliminating the limitations of traditional presser foot mechanical guidance.
3Reliability
If manual embellishment creation is performed, then unique designs can be made, but repeatability and accuracy are difficult to achieve
Solution Approach 1:
The system stores stitch patterns in the processor memory, allowing exact reproduction of embellishment designs. Each stitch pattern is pre-programmed with specific parameters including stitch length, width, and pattern type. The processor executes these stored patterns identically each time, ensuring high repeatability and accuracy without requiring manual skill consistency.
Solution Approach 2:
The system provides visual feedback through the display device showing the selected stitch pattern and operational status. The user interface confirms pattern selection and provides status information about the sewing process, allowing operators to verify that the correct pattern is being executed and to make adjustments if needed.
4Manufacturing precision
If automated computerized sewing is implemented, then precision and repeatability improve, but system complexity increases
Solution Approach 1:
The patent replaces complex manual operations with a computerized control system consisting of a processor and user interface. The processor handles pattern execution, needle control, and automated threading, while the user interface provides simple pattern selection and parameter adjustment. This substitution reduces the need for manual skill while maintaining precision through programmable control.
Solution Approach 2:
The system includes an automated needle threader mechanism that threads the needle without manual intervention. The processor automatically controls needle movement, stitch formation, and presser foot operation, reducing the need for operator intervention during the sewing process while maintaining high precision through programmable control.

AI summary
Aspects and embodiments of the present invention are directed to systems and methods for embellishing fabric. In accordance with embodiments, a stitching system for a sewing machine is provided comprising a processor configured to control the sewing machine and a user interface configured to receive a stitch selection corresponding to a set of commands executable by the processor to instruct the sewing machine to sew the stitch selection. The set of commands may comprise a first command to sew a first portion of the stitch selection, a second command to stop sewing after completion of the first portion, and a third command to sew a second portion of the stitch selection after completion of the second command. The systems and methods of the present invention may advantageously allow an operator to create a running sequence of perfectly replicated embellishments.
