Digital Mixer Screen Grouping for Rapid Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital mixers face operability issues due to the need for complex screen selection operations, as users must frequently switch between various settings on a large display, leading to inconvenient and time-consuming interactions, especially when frequently used screens are required.
Innovation Solution
A digital mixer with an operation panel featuring select buttons, a home button, and memory for storing screen specifying data, allowing for simple and efficient display of frequently used screens through predefined operations, such as long pressing the home button to assign a frequently used screen group, and automatic retrieval of the corresponding screen upon activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-purpose large display is provided on an operation panel to show various setting screens, then the digital mixer can display multiple functions, but the operation panel needs to have an enormous area
Solution Approach 1:
The display functionality is segmented into multiple selectable screen groups (e.g., channel settings, bus settings, matrix settings), each accessible through dedicated select buttons. This allows the large display to show different functional areas without requiring all controls to be physically present on the panel.
Solution Approach 2:
The large display serves multiple purposes by displaying different setting screens based on selected categories. A single display unit replaces what would otherwise require multiple dedicated displays or a much larger panel area with all controls.
2Adaptability or versatility
If screen selection relies only on user's screen specifying operation, then the digital mixer can display various settings, but the user has to perform complicated operations for screen selection
Solution Approach 1:
Screen groups are pre-categorized and assigned to specific select buttons before operation. Users don't need to navigate through multiple menus or perform complex sequences; they simply press the button corresponding to the desired screen category, and the system has already prepared that screen for display.
Solution Approach 2:
The system automatically determines which screen to display based on the select button pressed, without requiring the user to manually configure display settings or navigate through complex menus. The mixer serves itself by interpreting the select button input and autonomously displaying the appropriate pre-configured screen.
3Adaptability or versatility
If various setting screens are displayed by switching functions of a large display, then the digital mixer can provide multiple functions, but frequent screen switching becomes time-consuming
Solution Approach 1:
Multiple screen groups are pre-configured and stored in memory, each associated with a specific select button. When a user presses a select button, the corresponding pre-prepared screen is immediately displayed without requiring sequential navigation or multiple intermediate steps, significantly reducing screen switching time.

AI summary
A screen displayed in response to the selection of a tag button is called a tag screen and groups of the tag screens corresponding to the tag buttons are called screen groups. One of the screen groups is assigned to a home button as a home screen group, and clicking this home button when an arbitrary screen is displayed causes a large display to display a setting screen belonging to the home screen group. Here, in each of the screen groups, the selected tag button, the position of a mouse cursor, and so on are saved, and when an original screen is switched to another screen during an adjustment work or the like and the original screen is thereafter displayed again, the adjustment work or the like that was executed in the original screen can be continued at once.
