Embroidery Unit Y-Drive Mechanism Side Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional embroidery units require complex mechanisms for storage and detachment, leading to increased costs, space requirements, and potential pattern distortions due to rattle at joints, which hinders efficient normal sewing operations and compact storage.
Innovation Solution
An embroidery unit with a position switch mechanism that allows the Y-direction drive mechanism to be switched between an embroidery position on the upper surface and a stored position along the side surface, enabling easy storage and quick switching between embroidery and normal sewing without removing the unit from the sewing machine, thereby reducing space requirements and packaging costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the movable case is made larger to accommodate larger embroidery patterns, then the embroidery capability is improved, but the storage space requirement and packaging cost increase
Solution Approach 1:
The movable case is designed to be movable relative to the main casing, allowing it to extend forward and rearward. This dynamic configuration enables the case to accommodate larger embroidery patterns when needed while being able to retract to a compact position for storage, thus resolving the contradiction between embroidery capability and storage space requirement
Solution Approach 2:
The movable case can be disposed along the side surface of the main casing rather than only extending forward and rearward. This side surface disposal utilizes a different spatial dimension, reducing the footprint in the forward-rearward direction while maintaining the capability to accommodate large embroidery patterns, thereby reducing storage space requirements
2Productivity
If the embroidery frame carrier unit remains attached to the bed for normal sewing operations, then work efficiency is improved, but the movable case interferes with normal sewing operation
Solution Approach 1:
The movable case is designed to be movable and can be repositioned to avoid interfering with the needle and presser foot during normal sewing operations. This dynamic adjustment allows the embroidery frame carrier unit to remain attached to the bed for quick transitions between embroidery and normal sewing, improving work efficiency without compromising ease of operation
Solution Approach 2:
The embroidery frame carrier unit is divided into separable components, with the movable case being detachable from the main casing. This segmentation allows the movable case to be positioned or removed independently to avoid interference with normal sewing operations while maintaining the overall functionality of the unit
3Volume of stationary object
If the movable case is made detachable to reduce storage space, then storage compactness is improved, but the detachment mechanism increases cost and complexity
Solution Approach 1:
The embroidery frame carrier unit is segmented into a main casing and a movable case that can be detachably connected. This segmentation allows the movable case to be removed when not in use, achieving compact storage without requiring complex mechanisms - simply a detachable connection between two modular components
Solution Approach 2:
The movable case serves multiple functions: it houses the Y-direction carrier mechanism, can be extended to accommodate large embroidery patterns, and can be detached for compact storage. This multi-functionality is achieved through a simple detachable design rather than complex mechanisms, reducing overall device complexity

AI summary
An embroidery unit including a first switch mechanism rotating a Y-direction drive mechanism driving a carriage having a detachable embroidery frame holding a workpiece cloth connected thereto from the embroidery position to the upright position taking a vertical disposition, a second switch mechanism switching the Y-direction drive mechanism from the upright position to the stored position situated along a side surface of the unit body 31. Further, the upper surface of the exterior cover of the Y-direction cover and the upper surface of the bed are arranged to be substantially at level when the Y-direction drive mechanism is switched to the stored position.
