Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining operation information from sewing machines are limited, as they fail to detect and utilize information beyond the start or stop of rotation and thread trimming, limiting the effective utilization of sewing machine data.
Innovation Solution
An operation information obtaining device that includes a storage portion, estimation portion, and obtaining portion to associate detection information with sewing patterns, enabling the detection of complex sewing operations and patterns, and identifying potential issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional detection methods are used to obtain operation information from sewing machines, then the detection system remains simple, but the information obtained is limited to basic operations like start/stop and thread trimming
Solution Approach 1:
The patent segments the sewing pattern into multiple detection information points (e.g., needle position, thread trimming, backtacking) and detects each segment separately. This allows comprehensive operation information to be obtained without requiring a single complex detection system, as each aspect is detected by dedicated simple sensors.
Solution Approach 2:
The patent creates a universal detection system that can identify multiple types of sewing operations (sewing, backtacking, thread trimming, etc.) using a unified approach. The storage portion stores multiple sewing patterns with their respective detection information, allowing the system to universally detect various operations across different sewing machine types and patterns.
2Measurement precision
If basic detection methods are used, then the device complexity remains low, but the ability to identify poor conditions and analyze sewing patterns is insufficient
Solution Approach 1:
The patent performs preliminary action by storing multiple sewing patterns and their corresponding detection information in the storage portion before actual sewing operations. This pre-stored reference data enables accurate comparison and identification of poor conditions during sewing, improving measurement precision without requiring complex real-time analysis devices.
Solution Approach 2:
The patent implements feedback by comparing detected sewing pattern information against stored reference patterns to identify deviations and poor conditions. This feedback mechanism allows the system to accurately detect anomalies and provide precise measurement of sewing quality without adding significant device complexity.
