Embroidery Frame Bridge Radial Connector Tubular Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery systems with free arm sewing machines are limited in their ability to process tubular or pouch-type planar formations, especially those with small openings or long and tight configurations, due to restricted space and the need for a large opening to connect the embroidery frame, which prevents efficient embroidery of such materials.
Innovation Solution
The embroidery system incorporates an embroidery frame with a bridge that connects the inner and outer frames radially outside, allowing the embroidery module to be connected without requiring an opening in the planar formation, and features a first support with clearance for storing protruding material, enabling the use of different frame sizes and materials like plastic or metal for enhanced stiffness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the embroidery frame is connected directly to the primary connecting means, then the connection is simple and direct, but a large opening is required in the planar formation which limits the processing of tubular or pouch-type materials
Solution Approach 1:
The bridge acts as an intermediary component connecting the inner frame to the secondary connecting means. It extends radially outward to position the secondary connecting means outside the outer frame, eliminating the need for material to pass through the frame structure and enabling processing of tubular and pouch-type planar formations without large openings
2Volume of moving object
If the secondary connecting means is disposed inside the inner frame, then the structure is compact, but the planar formation must have an opening for connection which restricts material types
Solution Approach 1:
The bridge extends the connection in a radial dimension outward from the inner frame, positioning the secondary connecting means in a different spatial location (outside the outer frame) rather than keeping it inside the inner frame. This dimensional extension allows connection without requiring openings in the planar formation
3Volume of moving object
If the bridge is made longer to increase storage space for protruding material, then more material can be accommodated, but the bridge becomes more flexible and less stable
Solution Approach 1:
The bridge is made from a composite material comprising a thermoplastic matrix and glass fibers as reinforcement. The glass fibers provide high stiffness and dimensional stability, allowing the bridge to be made longer for increased storage space while maintaining sufficient rigidity and resistance to elastic deformations during embroidery operations
4Volume of moving object
If the embroidery module is positioned closer to the sewing machine, then the setup is compact, but there is insufficient clearance for protruding material and limited adaptability for different frame sizes
Solution Approach 1:
The connection system is segmented into multiple components: the inner frame, the bridge, and the secondary connecting means positioned outside the outer frame. This segmentation allows the embroidery module to be positioned at an optimized distance from the sewing machine while providing sufficient clearance for protruding material and accommodating different frame sizes through the extended radial configuration

AI summary
An embroidery system including an embroidery frame assembly having an inner first frame (51) and an outer second frame (53), a portion of a planar formation to be processed being able to be clamped therebetween. The first frame (51) is connected by a bridge (61) to a radially outer secondary connector (57), and a connecting portion (63) of this bridge (61) bridges the second frame (53) when the latter is connected to the first frame (51). When combined with an embroidery module connected to a free arm sewing machine, the embroidery frame assembly enables in a simple manner the embroidering of pouch-type and tubular planar formations.
