Embroidery Sewing Machine Applique Pattern Cutting Region Specification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing data generation devices and embroidery sewing machines are unable to efficiently create cutting and sewing data for applique patterns that differ from the shape of a target pattern based on the contour of the target pattern, limiting user convenience.
Innovation Solution
A processing data generation device and embroidery sewing machine that include an input portion, processor, and memory, capable of identifying a target pattern, acquiring a region specification command, and generating processing data for cutting out a specified cutting region from a workpiece, allowing users to create applique patterns that differ from the target pattern's shape by selecting appropriate cutting regions and generating corresponding cutting and sewing data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the known processing data generation device extracts contour of existing character font and creates cutting data and sewing data, then the device can generate processing data for standard fonts, but the device cannot generate applique patterns that differ from the shape of the target pattern
Solution Approach 1:
The system dynamically adjusts the cutting region based on user-selected commands (first command for inside region, second command for outside region). The processor determines different cutting regions according to the target pattern and the selected command type, enabling flexible pattern creation without fixed structural changes to the device.
Solution Approach 2:
The system changes the parameter of cutting region definition by introducing region specification commands. Instead of a fixed contour-based approach, the system accepts command parameters that specify whether to cut the inside or outside region of the target pattern, thereby creating diverse applique patterns from the same target pattern.
2Ease of operation
If the device follows the contour of the target pattern to create applique pieces, then the applique piece matches the target pattern shape, but the user cannot create applique patterns that differ from the target pattern shape
Solution Approach 1:
The cutting region is dynamically determined based on the target pattern and the region specification command. The processor adapts the cutting region to either the inside or outside of the target pattern according to user selection, making the system both easy to operate and flexible in pattern design.
Solution Approach 2:
The region specification command acts as an intermediary between the user's design intent and the actual cutting operation. This command mechanism allows users to specify different cutting regions without complicating the underlying processing system, thereby improving ease of operation while maintaining adaptability.
3Productivity
If the device generates cutting data based on target pattern contour, then the cutting process is simple and efficient, but the resulting applique piece has the same shape as the target pattern
Solution Approach 1:
The system maintains high productivity by using automated processor determination of cutting regions, while achieving pattern variety through dynamic selection between inside and outside region commands. The processor efficiently handles different command types without requiring manual intervention or complex processing changes.

AI summary
A processing data generation device includes an input portion, a processor, and a memory. The processor is configured to receive a detection signal of the input portion. The memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include pattern identification processing of identifying a target pattern, region specification command acquisition processing of acquiring, via the input portion, a region specification command to select, as a cutting region, a first region surrounded by an outside of the target pattern and by the target pattern, and processing data generation processing of creating processing data for cutting out, from a workpiece to be cut, the cutting region specified by the region specification command, as an applique piece.
