Sewing Machine Automatic Embroidery Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing sewing machines, adjusting the position of stitches for embroidery patterns is cumbersome, as users must manually arrange reference stitches before starting to sew, which is time-consuming and troublesome.
Innovation Solution
A sewing machine equipped with a processor and memory that generates stitched marker data to form reference stitches covered by the embroidery pattern, allowing for automatic detection and adjustment of sewing positions and angles, enabling seamless restart of the embroidery process based on detected markers and sewn patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually arrange reference stitches before starting to sew, then the sewing machine can maintain positioning accuracy, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The sewing machine automatically detects the stitched marker on the workpiece and calculates the sewing position and angle based on the marker's position, eliminating the need for users to manually arrange reference stitches. The system serves itself by using the detected marker position to automatically determine the embroidery pattern layout.
Solution Approach 2:
The reference stitch (stitched marker) is pre-formed on the workpiece before the embroidery pattern is sewn. This preliminary action allows the system to detect the marker position in advance and automatically calculate the correct sewing position and angle, removing the burden of manual arrangement during operation.
2Ease of operation
If the sewing machine automatically detects stitched markers and adjusts sewing positions, then position adjustment becomes easy, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical positioning operations with an automatic detection and calculation system. The processor detects the stitched marker position and automatically calculates the sewing position and angle, substituting complex mechanical adjustment mechanisms with software-based processing.
Solution Approach 2:
The stitched marker serves as an intermediary element between the workpiece and the sewing machine's positioning system. By detecting the marker's position and using it as a reference, the system simplifies the overall complexity while enabling automatic position adjustment.
3Productivity
If reference stitches are placed at needle drop points, then sewing can start immediately, but position adjustment operations become troublesome
Solution Approach 1:
The sewing machine automatically determines the needle drop point by detecting the stitched marker position and calculating the sewing position and angle. This self-service approach eliminates the need for users to manually place reference stitches at specific locations, allowing the machine to start sewing efficiently without troublesome adjustment operations.

AI summary
A sewing machine includes a sewing device, a processor, and a memory. The sewing device is configured to form stitches on a sewing workpiece. The memory is to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes including acquiring embroidery data, generating stitched marker data, causing the sewing device to sew the at least one stitched marker, causing the sewing device to start sewing an embroidery pattern, identifying a pattern to be sewn when the sewing of the embroidery pattern is stopped, detecting at least one of a second sewing position and a second sewing angle when the sewing of the embroidery pattern is stopped, setting at least one of a third sewing position and a third sewing angle, correcting data to be used to sew the pattern to be sewn, and causing the sewing device to restart sewing the embroidery pattern.
