Sewing Machine Embroidery Frame Type Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of mounting different types of embroidery frames on a sewing machine is complicated, requiring manual adjustment of a movable holder, which is time-consuming and prone to errors.
Innovation Solution
A sewing machine equipped with a frame support portion, a moving device, and a detecting device that automatically detects the type of embroidery frame by measuring the movement of a switching plate, allowing for simplified mounting and type identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a movable holder with an object to be detected is manually adjusted to detect embroidery frame type, then the detection function is achieved, but the mounting operation becomes complicated and time-consuming
Solution Approach 1:
The embroidery frame itself performs the detection function by incorporating the object to be detected directly onto the frame. When the frame is mounted on the frame support portion, the detection is automatically performed without requiring separate manual adjustment of a movable holder, thus achieving self-service detection.
Solution Approach 2:
The detection function is merged with the embroidery frame structure by placing the object to be detected directly on the frame. This combines the frame and detection components into a single integrated unit, eliminating the need for separate adjustment mechanisms and simplifying the mounting operation.
2Adaptability or versatility
If the object to be detected is placed on a movable holder requiring manual positioning, then flexible detection is achieved, but the mounting process complexity increases
Solution Approach 1:
The system automatically performs detection when the embroidery frame is mounted, eliminating the need for manual positioning of a movable holder. The frame itself serves as the detection platform, achieving self-service functionality that reduces operational complexity while maintaining adaptability.
Solution Approach 2:
The detection function is extracted from a separate movable holder and integrated directly onto the embroidery frame. This extraction eliminates the need for the complex movable holder positioning mechanism, simplifying the overall system while preserving the ability to detect different frame types.
3Measurement precision
If manual adjustment of the movable holder is required for each frame type change, then accurate detection is achieved, but the time required for frame type changes increases
Solution Approach 1:
The object to be detected is pre-positioned on the embroidery frame itself during frame manufacturing. This preliminary action ensures that when the frame is mounted, detection can immediately occur without requiring subsequent manual adjustment or time-consuming positioning operations.
Solution Approach 2:
The embroidery frame performs its own detection function through the integrated object to be detected, eliminating the need for separate manual adjustment steps. This self-service approach maintains accurate detection while significantly reducing the time required for frame type changes.

AI summary
A sewing machine includes a frame support portion, a moving device, a movable member and a detecting device. The frame support portion is configured to be detachably mounted with a mounting portion of an embroidery frame. The mounting portion has a specific shape that corresponds to a type of the embroidery frame. The moving device is configured to move the frame support portion. The movable member is configured to move in a first direction by a movement amount corresponding to the type of the embroidery frame, in conjunction with an operation in which the mounting portion of the embroidery frame is mounted on the frame support portion. The detecting device configured to detect the movement amount of the movable member, and to detect the type of the embroidery frame mounted on the frame support portion based on the detected movement amount.
