Rotating Inner Frame Embroidery Holder for Simplified Tensioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery frames face difficulties in holding sewing objects in a stretched state due to the complexity of the operation required, depending on the type and thickness of the object.
Innovation Solution
An embroidery frame design featuring a frame-shaped outer frame and an inner frame with a first member and a second member that rotate around a shaft, forming a frame shape along the outer frame's inner periphery, allowing for easier adjustment and holding of sewing objects by changing the distance between the frame's end portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjustment screw and coupling mechanism are used to tighten the outer frame with respect to the inner frame, then the sewing object can be held in a stretched state, but the operation becomes troublesome and complex
Solution Approach 1:
The inner frame is divided into a first member and a second member that can rotate relative to each other around a rotating shaft. This segmentation allows the frame to change its overall shape and size by rotating the second member between a first position (forming a frame shape) and a second position (folded position), simplifying the operation of adjusting the frame size to match different sewing object dimensions without requiring complex screw mechanisms
Solution Approach 2:
The second member is configured to be rotatably supported around a rotating shaft, enabling dynamic adjustment of the inner frame's dimensions. The frame can transition between different configurations (first position forming frame shape, second position folded) to adapt to various sewing object sizes and types, making the holding operation simpler and more versatile
2Adaptability or versatility
If the inner frame is designed with fixed dimensions, then the structure is simple, but it cannot adapt to different types and thicknesses of sewing objects
Solution Approach 1:
The inner frame incorporates a second member that can rotate around a rotating shaft relative to the first member. This dynamic configuration allows the frame to adjust its dimensions and shape by rotating the second member between a first position (where it forms part of the frame shape) and a second position (folded position), enabling adaptation to different sewing object sizes and types while maintaining a relatively simple structural design
Solution Approach 2:
The inner frame is segmented into a first member and a second member that can move relative to each other. This segmentation enables the frame to change its overall configuration by rotating the second member, providing adaptability to different sewing object dimensions without requiring a completely complex adjustable mechanism

AI summary
An embroidery frame includes a frame-shaped outer frame and an inner frame configured to hold a sewing object together with the outer frame. The inner frame includes a first member provided with a restriction portion, and a second member configured to be rotatably supported around a rotating shaft between a first position and a second position with respect to the first member. The second position is a position at which an angle of the second member with respect to the first member is a contact angle. The second member includes a contact portion. A first distance between a first end portion and a second end portion when the second member is in the first position is longer than a second distance between the first end portion and the second end portion when the second member is in the second position.
