Embroidery Frame with Rotatable Middle Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of existing embroidery frames for sewing machines is poor due to the need for users to manually fix the frames at intended angles using screws, which complicates the rotation and alignment process.
Innovation Solution
An embroidery frame design comprising an inner, middle, and outer frame with a grip portion that allows for easy rotation and adjustment, where the middle frame is detachably attached to the inner frame and the outer frame, enabling precise angle setting and improved usability through a grip portion that can be switched between use and stowed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indicators are provided on the outer frame and users manually fix the frames at intended angles using screws, then the embroidery frame can be assembled and held together, but the operability becomes poor due to complex rotation and alignment process
Solution Approach 1:
The embroidery frame is divided into three detachable frames (inner frame, middle frame, outer frame) that can be independently assembled and disassembled. The middle frame can be detached from the inner frame and reattached to the outer frame, allowing flexible configuration and easier operation without complex screw-fixing procedures.
Solution Approach 2:
The middle frame is designed to be rotatable relative to the outer frame, enabling dynamic adjustment of the frame angle during operation. This rotational capability allows the user to easily align the frame at intended angles without using screws, significantly improving operability.
2Ease of manufacture
If the middle frame is detachably attachable to the inner frame and outer frame, then the ease of assembly and disassembly is improved, but the structural stability may be compromised
Solution Approach 1:
The frame is segmented into three detachable components (inner frame, middle frame, outer frame) connected through standardized attachment interfaces. This segmentation enables easy assembly and disassembly while maintaining structural integrity through proper connection design.
Solution Approach 2:
The frames are arranged in a nested configuration where the inner frame is positioned within the middle frame, and the middle frame is positioned within the outer frame. This nested structure provides structural stability while allowing each frame to be independently attached and detached through simple operations.

AI summary
An embroidery frame comprises an inner frame, wherein the inner frame is a circular form. The embroidery frame comprises a middle frame which is configured to be detachably attachable to a radial outside of the inner frame. The middle frame is a circular form. The embroidery frame comprises an outer frame which is configured to rotatably hold the middle frame, wherein the outer frame is a circular form, and the outer frame is configured to be detachably attachable to a radial outside of the middle frame. The embroidery frame comprises a grip portion which is provided to the middle frame.
