Sewing Machine Character Embroidery Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing machines are unable to efficiently acquire and create embroidery data for character strings that include characters in a particular style, such as handwritten characters, leading to inefficiencies when users want to modify specific characters within the string, as the entire character string must often be re-acquired and re-processed.
Innovation Solution
A sewing machine equipped with a processor and memory that acquires image data of characters, extracts and generates embroidery data for each character, allowing for the selection and sewing of specific designs based on user input, enabling efficient creation and modification of embroidery patterns without re-processing the entire character string.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the sewing machine acquires image data of the entire character string and creates embroidery data all over again, then it can ensure the accuracy and completeness of the embroidery pattern, but it reduces operational efficiency and increases processing time
Solution Approach 1:
The patent segments the character string into individual character units, allowing the system to process and retrieve embroidery data for each character independently. This segmentation enables selective retrieval of only the modified character's embroidery data rather than reprocessing the entire character string, thus maintaining accuracy while improving operational efficiency.
2Productivity
If the sewing machine stores multiple character designs in advance, then it enables efficient selection and modification of specific characters, but it increases memory requirements and data storage needs
Solution Approach 1:
The patent uses image data as a compact representation of character designs. Instead of storing complete embroidery data for multiple character styles, the system stores image data that can be converted to embroidery data on-demand. This copying approach reduces storage requirements while maintaining the ability to efficiently select and modify specific characters.
3Stability of the object's composition
If the sewing machine processes the entire character string each time, then it ensures consistency across all characters, but it increases processing time and reduces responsiveness to user modifications
Solution Approach 1:
The patent performs preliminary processing by segmenting the character string into individual character units and pre-organizing their embroidery data. This preliminary segmentation allows the system to quickly retrieve and modify only the necessary character data when users make changes, maintaining consistency while significantly reducing processing time compared to reprocessing the entire character string.

AI summary
An apparatus includes a processor and a memory. The memory is configured to store computer-readable instructions therein, wherein the computer-readable instructions instruct the sewing machine to execute steps comprising acquiring image data including one or more characters, extracting, from acquired image data, one or more character designs with respect to each character included in the acquired image data, wherein the character design represents each character included in the acquired image data, generating embroidery data with respect to each character based on the extracted character design, wherein the embroidery data represents an embroidery pattern in a predetermined size.
