Embroidery Frame Transport Device Bobbin Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing embroidery frame transport devices are limited in their ability to retract a large embroidery frame from above the bobbin insertion opening, restricting the replacement of the lower thread bobbin during embroidery sewing.
Innovation Solution
The embroidery frame transport device incorporates a guide portion, a lever, and a locking portion to manage the movement of the embroidery frame, allowing it to be retracted from above the bobbin insertion opening by switching between restriction and release positions, enabling the frame to be moved in both directions for bobbin replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large embroidery frame is attached to the embroidery frame transport device, then the embroidery frame can be securely held and transported, but the embroidery frame cannot be retracted from above the bobbin insertion opening
Solution Approach 1:
The patent applies the dynamics principle by making the restriction portion movable between a restriction position (where it prevents frame movement) and a release position (where it allows frame movement). This is achieved through a lever mechanism that can be switched between different states, enabling the large embroidery frame to be both securely held during operation and retracted when needed for bobbin replacement
Solution Approach 2:
The patent changes the positional parameter of the restriction portion by moving it between restriction and release positions. This parameter change allows the system to adapt between two operational modes: securing the large embroidery frame during sewing and releasing it for bobbin replacement, thus resolving the contradiction between frame size and accessibility
2Stability of the object's composition
If the embroidery frame transport device restricts movement to maintain frame stability, then the frame remains secure during transport, but the frame cannot be retracted for bobbin replacement
Solution Approach 1:
The restriction portion is made dynamic rather than fixed, allowing it to switch between restricting and releasing frame movement. This enables the system to maintain frame stability during transport while also providing the flexibility to retract the frame when needed, addressing both stability and adaptability requirements
Solution Approach 2:
The embroidery frame transport device is designed with multi-functionality through the lever mechanism that controls the restriction portion. The same mechanism serves dual purposes: securing the frame for stable transport and releasing it for retraction, making the device adaptable to different operational needs without requiring separate mechanisms

AI summary
An embroidery frame transport device includes a guide portion, a lever, and a locking portion. The guide portion is configured to prescribe a first direction being a movement direction when the embroidery frame is removed and a second direction being a movement direction when the embroidery frame is mounted. The lever is configured to move between a first restriction position that restricts the movement in the first direction of the embroidery frame and a first release position that does not restrict the movement in the first direction of the embroidery frame. The locking portion is configured to move between a second restriction position that restricts the movement in the second direction of the embroidery frame and a second release position that does not restrict the movement in the second direction of the embroidery frame.
