Sewing Machine Display Interface Visibility and Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display input apparatus in sewing machines has a complex screen configuration, leading to insufficient visibility and operability.
Innovation Solution
The control apparatus sets a dark background for the input screen, displays the sewing pattern image with higher brightness than the background, and uses lighter colors for operation units, with increased brightness and blue coloration for buttons on which input operations are performed, and displays content units with higher brightness than the background.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex screen configuration is used in the display input apparatus, then more functions can be provided, but visibility and operability become insufficient
Solution Approach 1:
The screen is divided into multiple distinct regions with specific functions: a first region for displaying sewing pattern images and a second region for displaying operation units (buttons). This segmentation allows each region to be optimized independently - the first region provides comprehensive pattern display capabilities while the second region provides accessible control elements, resolving the contradiction between providing many functions and maintaining ease of operation.
Solution Approach 2:
Different regions of the screen are assigned different visual characteristics and functions. The first region uses visual representation of sewing patterns with specific color schemes, while the second region uses distinctly colored operation units (e.g., blue buttons) that stand out against the background. This local differentiation improves both functionality and operability by making the interface intuitive and easy to navigate despite the complexity of features available.
2Adaptability or versatility
If a complex screen configuration is used in the display input apparatus, then more functions can be provided, but visibility becomes insufficient
Solution Approach 1:
The patent applies specific color schemes to different screen regions to enhance visibility. Operation units are displayed in distinct colors (e.g., blue) that contrast with the background, and sewing pattern images use color representations that make them clearly visible. This color differentiation ensures that despite the complex functionality provided, all essential elements remain visually distinct and easily visible to the operator.
3Device complexity
If traditional display configurations are used, then device complexity remains low, but eye fatigue increases and color vision recognition becomes problematic
Solution Approach 1:
The patent applies local quality by creating a structured layout where operation units have distinct visual characteristics (different colors, specific positioning) that make them easily distinguishable without requiring complex processing. This localized visual differentiation reduces eye fatigue by making the interface intuitive and reduces the burden on color vision recognition, while maintaining overall design simplicity.
Solution Approach 2:
By segmenting the display into functional regions with clear visual separation, the patent reduces the cognitive load on operators. The segmented layout with distinct operation unit regions and pattern display regions creates a simpler visual hierarchy that is easier to process, reducing eye fatigue while providing comprehensive functionality.

AI summary
A sewing apparatus, includes a display input unit including a display unit configured to display an image of an input screen, and an input detection unit configured to detect an input operation on the input screen; and a control apparatus that performs display control of the display unit in response to the input operation. The control apparatus performs display control in which a background of the input screen is set to a dark color as a whole, a sewing pattern image displayed on the input screen is set to brightness higher than that of the background, and an operation unit that receives the input operation on the input screen is set to a color lighter than that of the background.
