Segmented Embroidery Holder for Dual-Side Fabric Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery techniques and equipment face challenges in securely holding fabric in place during embroidery on both sides, leading to inefficiencies and risks of misalignment.
Innovation Solution
A sewing workpiece holder with a frame assembly that includes a first and second frame, and brackets attachable to an embroidery machine, allowing for secure holding and easy switching between sides of the fabric for embroidery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional embroidery hoops are used to hold fabric, then the fabric can be secured in place during embroidery, but the fabric must be released and reattached when switching from one side to the other, which is time-consuming and risky for misalignment
Solution Approach 1:
The embroidery holder is divided into two separate frames (first frame and second frame) that can be independently attached to the fabric edges. This segmentation allows the holder to accommodate fabric of different sizes and enables selective attachment to specific edges, eliminating the need to release and reattach the entire fabric when switching sides.
Solution Approach 2:
The holder employs detachable and reconfigurable brackets that can be dynamically adjusted and repositioned. The brackets can be detached from one side and reattached to another side of the fabric without releasing the fabric from the holder, enabling dynamic reconfiguration for multi-side embroidery.
2Reliability
If traditional embroidery hoops are used to hold fabric, then the fabric can be secured in place during embroidery, but there is a risk of misalignment when releasing and reattaching the fabric
Solution Approach 1:
By segmenting the holder into two independent frames with separate attachment mechanisms, the system allows independent adjustment and attachment of each frame to the fabric edges. This reduces the complexity of handling the entire fabric sheet and minimizes misalignment risks associated with releasing and reattaching the whole fabric.
Solution Approach 2:
The holder is designed with pre-configured attachment mechanisms and guide structures that facilitate accurate positioning before attachment. The frames and brackets are designed with built-in alignment features that ensure proper positioning is achieved automatically during the attachment process, reducing misalignment risks.
3Adaptability or versatility
If a single frame is used to hold the fabric, then the structure is simple, but the fabric cannot be easily switched between different sides for embroidery
Solution Approach 1:
The holder is segmented into two distinct frames (first frame and second frame) that can be independently attached to opposite sides of the fabric. This segmentation provides versatility for embroidering both sides of the fabric while maintaining a relatively simple overall structure, as each frame is a straightforward component.
Solution Approach 2:
The holder design provides multi-functionality by enabling the same basic frame structure to serve multiple purposes: holding fabric for embroidery on the first side, holding fabric for embroidery on the second side, and accommodating fabric of various sizes. The detachable brackets can be repositioned to different locations on the frames, enhancing the versatility without significantly increasing complexity.

AI summary
Sewing workpiece holders for sewing machines and associated methods are disclosed herein. According to an aspect, a sewing workpiece holder includes a first frame that defines an opening. A second frame defines an opening. The second frame is configured to attach to the first frame and to hold a sewing workpiece therebetween. The openings of the first frame and the second frame substantially align when the second frame is attached to the first frame such that a portion of the sewing workpiece is exposed within the aligned openings when the sewing workpiece is held. A first bracket is attached to a first side of the first frame or the second frame. The first bracket is attachable to the sewing embroidery machine. A second bracket is attached to a second side of the first frame or the second frame. The second bracket is attachable to the sewing embroidery machine.
