Sewing Machine Embroidery Control with Line Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sewing machines require users to create embroidery data beforehand, which can be time-consuming and skill-dependent, limiting flexibility in creating embroidery patterns without manual operation.
Innovation Solution
A sewing machine with a horizontally moving embroidery frame, a reciprocally moving needle bar, and a control unit that allows users to input motifs and lines directly on a touch panel screen, enabling the machine to arrange motifs in sequence along designated lines without pre-created embroidery data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If embroidery data is created beforehand using a data inputting device, then embroidery sewing can be performed automatically without manual operation, but the preparation process becomes time-consuming and requires user skill to create accurate data
Solution Approach 1:
The system performs preliminary actions by automatically generating embroidery data through image recognition and pattern extraction from the sewing object image, eliminating the need for manual data creation while maintaining automated embroidery execution
Solution Approach 2:
The sewing machine performs self-service by automatically creating its own embroidery data through integrated image recognition and pattern extraction capabilities, without requiring external data input devices or manual data preparation
2Manufacturing precision
If embroidery data is created beforehand, then precise embroidery can be achieved without user skill, but the process requires complex data inputting devices and preparation steps
Solution Approach 1:
The system merges the image recognition function, pattern extraction function, and embroidery data generation function into a single integrated process within the sewing machine, eliminating the need for separate complex data inputting devices
Solution Approach 2:
The system replaces manual mechanical data input operations with automated image recognition and pattern extraction processing, substituting physical data entry mechanisms with computational algorithms
3Adaptability or versatility
If the user manually turns the sewing object to change motif arrangement direction, then flexibility in motif arrangement is achieved, but the user requires skill and concentration to precisely achieve the desired sewing
Solution Approach 1:
Instead of manually rotating the sewing object to change motif direction, the system inverts the approach by keeping the sewing object stationary and automatically adjusting the motif arrangement direction through image recognition and coordinate transformation based on the sewing object's orientation

AI summary
A sewing machine includes a embroidery frame that moves horizontally while stretching and supporting a sewing object, a needle bar that supports a needle that penetrates a needle thread in the sewing object, and that reciprocally moves relative to the sewing object stretched by the embroidery frame, and a control device that controls the horizontal movement of the embroidery frame and the reciprocal motion of the needle bar. This control device includes a line input unit that accepts selection of the motif and input of a line which the motifs are arranged on in sequence. In addition, the control device horizontally moves the embroidery frame a way that the motifs selected using the line input unit are arranged in sequence on the sewing object along the line.
