Sewing Process Visualization with Slip Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sewing and embroidery machines struggle to display complex stitching and embroidery patterns realistically, as they fail to accurately represent the sewing material, needle thread, and bobbin thread colors and structures, making it difficult to discern individual stitch sequences and actual conditions.
Innovation Solution
A method and device that utilize high-resolution monitors to simulate sewing and embroidery processes by selecting or detecting the sewing material's color and structure, and predetermining thread characteristics, allowing for realistic visualization during operation or simulation mode, with slip-correction factors to account for material movement, enabling the display of stitch formation without actual sewing on original material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If complete stitching and embroidery patterns are displayed on the monitor, then the entire pattern information is visible, but individual stitching sites and needle stitch sequences become hardly discernible
Solution Approach 1:
The patent divides the complete stitching pattern into individual stitching sites and needle stitch sequences that can be displayed separately and sequentially. This segmentation allows the system to show the entire pattern overview while enabling detailed examination of individual stitch elements through controlled display sequencing.
Solution Approach 2:
The patent implements periodic display of stitching information by showing individual stitching sites and needle stitch sequences in a sequential, time-based manner. This periodic action allows the complete pattern to be displayed over time while maintaining clarity of individual stitch elements through rhythmic presentation.
2Device complexity
If conventional representations of stitching patterns are used, then the display is simple, but the actual conditions including color, structure, and thread characteristics are not reflected
Solution Approach 1:
The patent creates a virtual copy of the actual sewing process that replicates material colors, thread characteristics, and structure properties on the monitor. This copying approach preserves all relevant visual information about the sewing process while maintaining display simplicity through software-based simulation rather than physical samples.
Solution Approach 2:
The patent changes the display parameters to include color information, material structure, and thread characteristics by adjusting the visualization parameters of the monitor display. This allows the system to present comprehensive information about sewing conditions by modifying how the data is rendered rather than adding physical complexity.
3Measurement precision
If a high-resolution monitor is used to show detailed stitching processes, then realism is improved, but the cost and complexity of the system increases
Solution Approach 1:
The patent replaces physical mechanical systems (actual sewing on material samples) with a software-based simulation system that runs on the monitor. This substitution achieves high visualization realism through digital rendering of stitching processes while avoiding the complexity of additional physical hardware components.

AI summary
A method and the device for displaying sewing processes to allow simulation of the formation of stitch patterns and embroidery patterns in sewing machines (1) and embroidery machines or in sewing simulators close to reality is provided. In the representation on the monitor (3) features, such as colors and the structure of the sewing material (2), are considered. By activating a simulation mode, the drive for the stitch formation unit can be disabled.
