Generating thread stitch coloring data for an in-line thread coloring process
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thread consuming devices, such as embroidery machines, face challenges in managing color transitions during in-line thread coloring processes, leading to inconsistent color changes, operational inefficiencies, and reduced quality due to smeared colors.
Innovation Solution
A computer-implemented method for generating thread stitch coloring data that converts traditional embroidery data into in-line thread coloring data by accounting for residual stitches required for color changes, ensuring precise color transitions through a control unit and treatment unit with discharge devices to dispense coating substances onto the thread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional pre-colored threads are used in embroidery devices, then thread changes are frequent and design creativity is limited, but color transitions are simple and consistent
Solution Approach 1:
The patent applies parameter changes by dynamically altering the color parameter of the thread during the embroidery process. Instead of using pre-colored threads with fixed color parameters, the system changes the color parameter in real-time through in-line thread coloring technology, allowing versatile designs while maintaining operational efficiency through automated color management.
Solution Approach 2:
The patent introduces an intermediary system - the in-line thread coloring device - that acts as a mediator between the single white thread source and the final multi-colored embroidery pattern. This intermediary dynamically colors the thread during consumption, enabling design versatility without requiring multiple pre-colored thread sources or frequent manual thread changes.
2Adaptability or versatility
If in-line thread coloring is used to enable versatile designs, then thread changes are reduced, but color transitions become difficult to manage with smeared colors
Solution Approach 1:
The patent applies preliminary action by pre-calculating and determining the exact number of residual stitches required for each color transition before the embroidery process begins. The system analyzes the decorative pattern data to identify color boundaries and computes the precise stitch count needed to complete color changes, preventing color smearing by ensuring color transitions occur at the correct positions.
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring the embroidery process and comparing actual thread consumption against the pre-calculated residual stitch data. The control unit adjusts the in-line coloring process based on this feedback, ensuring that color transitions occur at the precise intended positions and maintaining manufacturing precision throughout the embroidery process.
3Device complexity
If color transitions are managed without residual stitch data, then the process is simpler, but color substances are smeared out and quality is reduced
Solution Approach 1:
The patent applies preliminary action by pre-calculating the residual stitch data for all color transitions in the decorative pattern before embroidery begins. The control unit analyzes the pattern data to determine exact color boundaries and computes the precise number of stitches needed for each color change, storing this information for use during the embroidery process to prevent color smearing.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating buffer stitches around color transition zones. These additional stitches act as a cushion or buffer zone that ensures color substances are properly deposited and settled before and after transitions, preventing smearing while maintaining the overall simplicity of the in-line coloring process.

AI summary
A computer-implemented method for generating thread stitch coloring data for an in-line thread coloring process, comprising: obtaining first thread stitch coloring data based on a digital representation that is to be produced as a decorative thread pattern; obtaining at least one thread color boundary defining a color change from a first color to a second color; determining residual stitch data based on the at least one thread color boundary being indicative of a number of residual stitches required in order to carry out said color change in an in-line thread coloring process; and generating second thread stitch coloring data based on the residual stitch data such that the color change of the first thread stitch coloring data is accounted for in the in-line thread coloring process.
