Electronic Sewing Machine Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic sewing machines face increased user load and operation time due to complex operations and frequent screen switching on display units, with audio notifications becoming unnecessary for experienced users and potentially annoying when repeatedly used.
Innovation Solution
An electronic sewing machine with an illustration data storage unit, a display unit, an audio data storage unit, and an audio output unit that displays illustration data without text and provides corresponding audio explanations, allowing minimal screen switching and user load reduction, with optional audio output control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display unit dimensions are increased to display all illustrations and explanations simultaneously, then the information completeness is improved, but the device complexity and cost increase
Solution Approach 1:
The display content is segmented into multiple screens that are displayed sequentially. The control unit divides comprehensive operation explanations into multiple manageable screens, each showing a specific aspect of the sewing machine operation. This allows complete information to be conveyed without requiring a large display unit, as users can navigate through multiple screens using operation buttons.
Solution Approach 2:
The display unit shows information in periodic cycles, switching between different screens of illustrations and explanations. The control unit automatically advances through screens or allows user-controlled navigation, presenting complete information over time rather than requiring all information to be displayed simultaneously. This temporal segmentation resolves the contradiction between information completeness and display size.
2Loss of time
If the screen switching operations are reduced by displaying all information at once, then the operation time is reduced, but the display unit dimensions must be increased
Solution Approach 1:
The display system is made dynamic through automatic screen switching and user-interactive navigation. The control unit automatically transitions between screens at predetermined intervals or in response to user inputs, creating a dynamic information delivery system. This dynamic approach allows complete information to be conveyed through sequential display rather than requiring a static large display, reducing operation time without increasing display dimensions.
Solution Approach 2:
The system incorporates feedback mechanisms where user operations (button presses, screen selections) control the display progression. The control unit receives user input and adjusts screen display accordingly, allowing users to navigate through information at their own pace. This feedback loop enables efficient information delivery through multiple screens without requiring users to manually switch screens repeatedly, reducing operation time while maintaining compact display size.
3Device complexity
If the illustrations and explanations are displayed in small size to fit on a single screen, then the display unit dimensions are maintained, but the load on the user's eyes increases
Solution Approach 1:
Visual information is segmented into multiple screens, each displaying a specific set of illustrations and explanations in larger, more readable sizes. Rather than compressing all information into one small screen, the control unit divides content across multiple screens, allowing each screen to present information at an optimal viewing size. This segmentation reduces eye strain while maintaining compact display unit dimensions.
Solution Approach 2:
The display unit periodically presents different screens of information, allowing users to view larger illustrations and explanations on each screen before transitioning to the next. This temporal separation of information presentation allows each screen to use larger font sizes and clearer illustrations without requiring all information to be visible simultaneously, reducing eye load while maintaining display size constraints.
Data Source
AI summary
An electronic sewing machine (M) which makes a needle bar move up and down through a sewing machine spindle which is driven by a sewing machine motor of the sewing machine body provided with an illustration data storage unit (15) which stores a plurality of illustration data, a display unit (4) which displays the illustration data which is stored in the illustration data storage unit, an audio data storage unit (20) which stores audio data which corresponds to the illustration data, and an audio output unit (21) which outputs audio data which is stored in the audio data storage unit and displaying the illustration data on the display unit while outputting audio data corresponding to the illustration data from the audio output unit. Due to this, preferably illustration data which can reduce the frequency of screen switching to reduce the load of the operator without increasing the size of the display unit is data for explaining a method of use of the sewing machine and the audio data is data of explanations corresponding to the illustration data.
