Sewing Machine Magnifier with Detachable Lens and Turning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnifiers for sewing machines have complex structures and are large in size, making them difficult to adjust and potentially interfere with the sewing operation, and do not adequately accommodate operators with varying eyesight and fields of view.
Innovation Solution
A magnifier system for sewing machines featuring a supporting arm with a detachable lens holding part and a lens main body that can be adjusted to various angles using a turning control unit, allowing for easy horizontal and vertical positioning without obstructing the sewing operation, and can be easily detached for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnifier with high adjustment freedom is provided, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The magnifier is divided into separate components: a lens unit, a support arm with mounting portion, and a turning control unit. This segmentation allows each part to be optimized independently - the lens can be adjusted for magnification, the support arm provides positioning, and the turning control unit enables angle adjustment without complicating the overall structure.
Solution Approach 2:
The magnifier incorporates a turning control unit that allows dynamic angle adjustment of the lens relative to the support arm. This dynamic capability enables the lens to be rotated to various angles during operation, providing adjustment freedom while maintaining a relatively simple fixed mounting structure.
2Adaptability or versatility
If a large-type magnifier is provided, then the adjustment freedom is improved, but the harmful factors increase due to interference with sewing operation
Solution Approach 1:
The magnifier is designed with a compact lens unit that provides high magnification power in a small form factor. This allows the magnification function to be concentrated in a localized area that does not extend into the sewing operation space, eliminating interference while maintaining adaptability through angle adjustment.
Solution Approach 2:
Instead of increasing the physical size of the magnifier to gain adjustment freedom, the invention utilizes angular adjustment in a different dimension. The lens can be rotated to various angles around the support arm, providing versatility without occupying more space in the sewing area.
3Reliability
If existing magnifiers are provided, then basic magnification is achieved, but the adaptability to different operators' eyesight and fields of view is insufficient
Solution Approach 1:
The magnifier is designed with universal adaptability through multiple adjustment capabilities: magnification power can be changed by replacing lens units, and the viewing angle can be adjusted using the turning control unit. This multi-functionality allows the same device to accommodate different operators' eyesight requirements and field of view preferences.
Solution Approach 2:
The magnifier allows operators to change key parameters including magnification power (by selecting different lens units) and viewing angle (by using the turning control unit). These parameter changes enable the device to adapt to different operators' visual requirements while maintaining reliable magnification functionality.
