Sewing Machine Display Page Navigation via Mouse Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sewing machines with display devices for multiple sewing patterns and information require complex operations to navigate and select desired patterns, especially when patterns are categorized, leading to cumbersome user interactions.
Innovation Solution
A sewing machine with a display device, operation device, and display control system that allows for intuitive page navigation using a mouse wheel for rolling operations, enabling easy selection and display of desired patterns by incrementing or decrementing display sequential orders, thereby simplifying the operation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patterns are classified into multiple categories and displayed category-by-category, then pattern organization and selection clarity are improved, but the operation complexity increases requiring separate category selection and page navigation
Solution Approach 1:
The patent combines category selection and page navigation functions into a single operational sequence. By using a single operation member (mouse wheel) that performs both category switching and page turning through sequential rolling operations, the system merges what were previously separate control functions into one unified interaction mechanism, thereby reducing operational complexity while maintaining organized pattern display
Solution Approach 2:
The operation member (mouse wheel) is designed to perform multiple functions: it can switch between categories and navigate through pages within categories using the same physical component. This multi-functionality eliminates the need for separate control mechanisms for category selection and page navigation, simplifying the overall operation process while preserving the benefits of categorized pattern organization
2Ease of operation
If separate page change keys and category change keys are provided, then precise control over display navigation is achieved, but the number of operating members increases
Solution Approach 1:
A single operation member (mouse wheel) is designed to perform multiple navigation functions. By programming the control unit to interpret sequential rolling operations as either category switches or page turns, the system achieves precise display navigation control without requiring physically separate control keys, thereby reducing device complexity while maintaining operational precision
Solution Approach 2:
The patent merges the functions of page change keys and category change keys into one unified operation member. The control unit distinguishes between different operational modes (category switching vs. page turning) based on the sequence and context of mouse wheel operations, combining what were previously separate control functions into a single integrated control mechanism

AI summary
A sewing machine and a sewing machine operating program stored on a computer-readable medium for changing display items displayed on a liquid crystal display of a sewing machine on a page by page basis, when an output signal of an operation of rolling forward or backward a mouse wheel is detected. The sewing machine may include a display device that displays a variety of information related to sewing and a display item storage device that stores display items to be displayed on the display device. The sewing machine may also include an operation device that includes an operating member for performing plural types of operations and a display control device that changes the display item displayed on the display device in response to at least one of the operation type or the operation quantity outputted by the operation device.
