Solution Overview

Problem

Conventional embroidery data generating devices require time-consuming and laborious manual adjustment of thread colors for each color-based pattern portion, leading to potential visibility issues when darker threads are sewn under lighter ones, affecting the quality of the embroidery pattern.

Innovation Solution

An embroidery data generating device that randomly selects colors from a stored palette and assigns them to color-based pattern portions based on their overlapping density, ensuring that colors are sequenced to prevent darker threads from being visible through lighter ones, thereby enhancing the quality and efficiency of the embroidery process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual adjustment of thread colors is performed for each color-based pattern portion, then the quality of embroidery pattern can be ensured, but the time and labor required increases significantly

Engineering Contradiction:

Improvequality of embroidery patternVSAvoidtime and labor for color adjustment

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system automatically determines thread color visibility issues and adjusts color sequences without manual intervention. The control unit autonomously analyzes the embroidery pattern data, identifies overlapping color-based pattern portions, and rearranges the sewing sequence to prevent darker threads from being visible through lighter ones, eliminating the need for manual color adjustment while maintaining quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system incorporates a feedback mechanism where the control unit evaluates the embroidery pattern data, detects potential visibility issues based on color density and overlapping regions, and automatically adjusts the sewing sequence. This closed-loop approach ensures quality maintenance while reducing manual time investment.

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If thread colors are corrected to prevent visibility issues, then the quality of embroidery pattern is improved, but the flexibility in color selection is reduced

Engineering Contradiction:

Improvequality of embroidery patternVSAvoidflexibility in color selection

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary analysis of the embroidery pattern data to identify overlapping color-based pattern portions and potential visibility issues before sewing begins. By pre-determining the optimal sewing sequence based on color density and overlap relationships, the system maintains color flexibility while preventing visibility issues through automated sequence adjustment rather than color correction.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If data of color-based pattern portions is read one by one for color designation, then precise color control is achieved, but the process becomes time-consuming and troublesome

Engineering Contradiction:

Improveease of color designationVSAvoidtime for reading and confirming data

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The system merges multiple color-based pattern portion data into a unified analysis process. The control unit processes all overlapping regions and color sequences simultaneously, identifying visibility issues and determining optimal sewing sequences in a single automated operation, thereby eliminating the need to read and confirm each color-based pattern portion individually.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An embroidery data generating device generates embroidery data usable to sew by a sewing machine an embroidery pattern composed of a plurality of color-based pattern portions. The device includes a color data storage unit storing data of a plurality of defined colors, an assignment unit randomly extracting a color from the color data stored on the color data storage unit, the extracted color being used as thread color data for specifying colors of the color-based pattern portions respectively, the assignment unit assigning the extracted colors to the respective color-based pattern portions and a sewing sequence data storage unit storing data of set sewing sequence of the color-based pattern portions. The device generates embroidery data in which an order of contrasting density of the colors assigned to the respective color-based pattern portions by the assignment unit as the thread color data corresponds to a sewing sequence of the color-based pattern portions.
