Sewing Machine Control Device for Editable Pattern Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beginner users find it difficult to create sewing data for new patterns from scratch on existing sewing machines, as the process is not user-friendly.
Innovation Solution
A sewing machine equipped with a needle bar, feed mechanism, swinging mechanism, display device, and control device that allows users to select and edit existing sewing data for patterns, enabling the creation of new patterns by modifying and combining existing ones, with a non-transitory computer-readable medium storing a control program to facilitate this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user creates sewing data for a new pattern from scratch on existing sewing machines, then the sewing machine can perform sewing operations, but the process is difficult and not user-friendly for beginners
Solution Approach 1:
The system performs preliminary action by automatically detecting and extracting useful information from existing patterns before the user needs to create new sewing data. The control device analyzes stored pattern data, identifies editable elements, and prepares a simplified interface that presents only the necessary editing options, thereby reducing the complexity of the pattern creation process for beginners.
Solution Approach 2:
The system uses copying by allowing users to select existing patterns from storage and create new patterns based on copies of these existing patterns. Instead of creating sewing data from scratch, users can copy and modify existing pattern data, which significantly simplifies the operation and makes the system more user-friendly while maintaining the functionality to perform sewing operations.
2Adaptability or versatility
If the sewing machine provides comprehensive pattern creation capabilities, then it can handle various sewing needs, but the interface and operation become more complex
Solution Approach 1:
The system applies segmentation by dividing the pattern creation process into distinct manageable steps: pattern selection from storage, identification of editable elements, and application of editing operations. This segmentation allows users to interact with only the necessary portions of the system at each step, maintaining versatility while improving ease of operation through a simplified, step-by-step interface.
Solution Approach 2:
The control device acts as an intermediary between the user and the complex pattern data storage system. It mediates by automatically analyzing stored patterns, determining which elements are editable, and presenting a simplified interface that translates user-friendly editing commands into the necessary pattern modifications, thereby maintaining versatility without increasing operational complexity.

AI summary
A sewing machine includes a needle bar, a feed mechanism, a swinging mechanism, a display device, and a control device. The control device determines whether each one of a plurality of sets of sewing data for sewing a pattern is editable, displays on the display device, editable pattern described by the sewing data that has been determined to be editable, and acquires a selection command that selects an object pattern from among the editable pattern. The control device also acquires edit command to edit the selected object pattern, edits object sewing data that are for the object pattern, in accordance with the edit command that has been acquired, and causes the sewing machine to sew the object pattern on a sewing workpiece, based on the edited object sewing data, by operating the feed mechanism that moves the sewing workpiece and the swinging mechanism that swings the needle bar.
