Data Processor Reference Mark Alignment for Embroidery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for forming embroidery patterns on workpieces require significant user effort and time for precise positioning of image patterns transferred from thermal sheets, and existing solutions increase the complexity and cost of embroidery machines due to the need for image sensors and complex correction programs.
Innovation Solution
A data processor and program that use reference marks printed on thermal transfer sheets to facilitate precise positioning of image and embroidery patterns by determining the relative positioning between the image pattern, embroidery pattern, and reference mark, allowing the embroidery frame to conform to the reference mark for simplified alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If reference marks are printed on thermal transfer sheets to facilitate positioning, then positioning precision is improved, but device complexity increases due to need for image sensors and correction programs
Solution Approach 1:
The patent uses reference marks printed on the thermal transfer sheet as a simple copy or representation of positioning information. Instead of using complex image sensors to detect and analyze features, the system creates a printed copy of reference positions directly on the transfer medium, which can be read optically without requiring sophisticated detection hardware or complex correction algorithms.
2Manufacturing precision
If manual positioning adjustment is required for embroidery patterns relative to image patterns, then positioning precision can be achieved, but loss of time increases due to substantial user effort
Solution Approach 1:
The patent applies preliminary action by pre-printing reference marks on the thermal transfer sheet before the actual embroidery and printing processes. This preliminary positioning information is embedded in the transfer sheet itself, so that when the sheet is thermally transferred to the fabric, the reference marks are transferred along with the image pattern. This eliminates the need for manual positioning adjustments afterward, as the reference marks provide automatic alignment guidance for the embroidery pattern placement.

Function Achieved in This Case
This approach simplifies the positioning of embroidery patterns relative to image patterns, reducing user effort and machine complexity, while maintaining precise alignment without the need for additional sensors or complex correction programs, thereby enhancing efficiency and reducing costs.
Implementation Method 1
the image pattern printed on the thermal transfer sheet is thermally transferred onto the workpiece cloth
