Sewing Machine Input Interface Front Plate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of the input interface in sewing machines is compromised when users handle them from the side, particularly when the interface is positioned at the end of the arm in the Y direction, leading to decreased usability and increased complexity in operating the machine, especially when working with tubular workpieces.
Innovation Solution
The sewing machine design includes a column, bed, and arm where the input interface is positioned on a front plate at the end of the arm in the first particular direction, perpendicular to the upper-lower direction, allowing for improved accessibility and operability by positioning the bed inside tubular workpieces and enabling the carriage to move in this direction, thus enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the input interface is arranged on a plate located at one end of the arm in the Y direction, then the sewing machine structure is simplified, but the operability of the input interface by a user is deteriorated
Solution Approach 1:
The patent repositions the input interface from a lateral arrangement (Y direction) to a front-facing arrangement on the arm's front plate. This dimensional change in interface placement allows users to access the interface from the front direction, improving operability while maintaining structural simplicity.
2Adaptability or versatility
If the bed is placed inside the tubular workpiece, then the sewing machine can handle tubular workpieces effectively, but the accessibility to the input interface may be compromised
Solution Approach 1:
The patent positions the input interface on the front plate of the arm, facing the user from the front direction. This front-facing arrangement ensures that users can easily access and operate the interface even when the bed is positioned inside tubular workpieces, as the interface remains accessible from the front rather than requiring lateral access.

AI summary
A sewing machine includes a column, a bed, an arm, and an input interface. The column extends in an upper-lower direction. The bed extends in a first particular direction from the column at a position above a lower end of the column. A first direction includes the first particular direction and a first opposite direction opposite to each other. The first direction is perpendicular to the upper-lower direction. The arm extends in the first particular direction from the column at a position spaced upward from the bed. The input interface is arranged on a front plate. The front plate is a plate located at an end of the arm in the first particular direction. The input interface is an interface for operating the sewing machine.
