SEWING MACHINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524367 titled 'SEWING MACHINE

Simplified Explanation

The patent application describes a sewing machine with a projection unit and a photographing unit for enhanced functionality.

• The arm of the sewing machine includes a head on one side, a needle bar for reciprocating movement, and a feed mechanism for moving a workpiece.
• The projection unit projects an image towards a bed using image light emitted by an emitter.
• The photographing unit captures a target using light reflected by the target on an incident portion.
• Both the emitter and incident portion are positioned towards one side of the arm and head, in specific directions relative to the needle bar.

Potential Applications

The technology described in this patent application could be applied in the development of advanced sewing machines for industrial or commercial use, where precise projection and imaging capabilities are required.

Problems Solved

This technology solves the problem of accurately projecting images and capturing targets in a sewing machine, allowing for improved precision and efficiency in sewing operations.

Benefits

The benefits of this technology include enhanced functionality, increased accuracy in sewing tasks, and potential for automation and integration with other technologies for improved productivity.

Potential Commercial Applications

The technology could be commercialized in the sewing machine industry for the production of high-end machines with advanced features for professional seamstresses, tailors, and garment manufacturers.

Possible Prior Art

One possible prior art could be sewing machines with basic projection or imaging capabilities, but not the specific combination of features described in this patent application.

How does the projection unit interact with the feed mechanism during sewing operations?

The patent application does not provide details on the specific interaction between the projection unit and the feed mechanism while sewing. This aspect could be crucial in understanding the overall functionality of the machine.

What materials are compatible with the photographing unit for capturing targets?

The patent application does not specify the types of materials or surfaces that the photographing unit can effectively capture. Understanding the limitations and capabilities of this unit is essential for determining its practical applications.

Original Abstract Submitted

In a sewing machine, an arm includes, on one side thereof in a first direction, a head. A needle bar is disposed at the head to reciprocally move in a second direction. A feed mechanism feeds a workpiece from one side toward the other side of the head in a third direction. The projection unit disposed at the head projects a projection image toward a bed. The projection unit includes an emitter for projecting image light of the projection image. The photographing unit disposed at the head captures a photographing target. The photographing unit includes an incident portion on which light reflected by the photographing target is incident. The emitter and the incident portion are disposed further toward the one side of the arm in the first direction than the needle bar, and further toward the one side of the head in the third direction than the needle bar.
