Embroidery Decoration Pattern Data Generation via Automated Outline Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for setting a decoration pattern sewing area around an embroidery pattern are inaccurate due to reliance on manual drawing, which varies with operator skill and dexterity.
Innovation Solution
A decoration pattern data generating apparatus that selects an embroidery pattern, specifies its outline, and sets an area outside the outline as a decoration area, generating data for sewing a decoration pattern in that area using a sewing machine with a controller and camera for precise image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual drawing method is used to set decoration pattern sewing area, then operator can flexibly adjust the area, but the accuracy of the drawn outline varies with operator skill level and dexterity
Solution Approach 1:
The patent replaces the manual mechanical drawing operation with an automated image processing system. The controller automatically generates the outline by processing the captured image of the embroidery pattern, eliminating the need for manual drawing while ensuring consistent accuracy. This substitution resolves the contradiction by maintaining operational flexibility through automated control while achieving precise and consistent outline accuracy regardless of operator skill level.
2Manufacturing precision
If automated image processing is used to specify outline, then accuracy of decoration area setting is improved, but device complexity increases due to camera and controller requirements
Solution Approach 1:
The patent integrates multiple functions into the sewing machine's existing controller, which not only controls the sewing operations but also performs image processing to generate the decoration pattern outline. The camera captures images that are processed by the same controller that manages the sewing needle and needle bar. This multi-functionality approach reduces device complexity by avoiding the need for separate dedicated outline generation equipment, while still achieving high accuracy in decoration area setting.
Data Source
AI summary
A decoration pattern data generating apparatus includes: a controller, the controller being configured to control the decoration pattern data generating apparatus to select an embroidery pattern to be sewn, specify an outline of the embroidery pattern, based on embroidery pattern data for sewing the selected embroidery pattern; set an area outside the specified outline, as a decoration area; and generate decoration pattern data for sewing a decoration pattern in the set decoration area.
