Embroidery Data Creation Apparatus Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional embroidery data creation apparatuses often produce stitches in undesirable directions, particularly in regions with minimal luminance differences, leading to uneven and unnatural embroidery results.
Innovation Solution
An embroidery data creation apparatus and program that calculates angle characteristics and intensities for each pixel, allowing for the modification of stitching directions in specific regions based on user input, ensuring higher continuity and natural alignment of stitches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If angle characteristics are calculated based on luminance differences between pixels, then stitching direction can be determined automatically, but in regions with minimal luminance differences the stitching direction becomes inaccurate and unnatural
Solution Approach 1:
The system allows the user to interactively specify the desired stitching direction by dragging the mouse, and the system automatically applies this user-specified direction to the embroidery data creation process, making the system serve the user's intent directly
Solution Approach 2:
The system changes the angle characteristic parameter in the specified region from being automatically calculated based on luminance to being set by user input, thereby overriding the automatic calculation with a user-defined value for that specific region
2Productivity
If the entire image is processed with automatic angle characteristic calculation, then processing is efficient, but regions requiring specific stitching directions cannot be distinguished
Solution Approach 1:
The system applies different angle characteristic determination methods to different regions: automatic calculation based on luminance for most regions, and user-specified angle characteristics for locally identified regions of interest, thereby achieving both efficiency and adaptability
Solution Approach 2:
The user acts as an intermediary to specify stitching directions for particular regions, bridging the gap between automatic processing and precise control by providing targeted input only where needed
3Ease of operation
If stitching direction is specified by moving mouse cursor over embroidery region, then user can control stitching direction, but the process is time-consuming and complex
Solution Approach 1:
The system segments the embroidery region into ordinary regions (processed automatically) and regions of interest (processed with user input), so the user only needs to specify directions for specific segments rather than the entire region
