Operation Console Numeric Key Positioning Across Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multifunctional peripherals (MFPs) face confusion and increased operation time due to the need to locate numeric keys at different positions on the touch-panel display when switching between operational modes, leading to potential erroneous operations.
Innovation Solution
An operation console with a display unit and detecting unit that maintains numeric information, including numeric keys, at a consistent position on the touch-panel display across different operational modes, allowing users to input numerical values efficiently by ensuring the keys are always displayed in the same arrangement and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operational mode is changed and screen image is switched accordingly, then the display shows appropriate information for each mode, but the numeric keys are positioned at different locations causing user confusion and increased operation time
Solution Approach 1:
The numeric key input area is designed to serve multiple operational modes (copy mode, FAX mode, scanner mode, etc.) while maintaining a consistent position on the touch-panel display. This universal positioning allows users to input numerical values across different modes without needing to locate keys anew, resolving the contradiction between mode-specific display adaptation and operational ease.
2Adaptability or versatility
If the screen image is switched for each operational mode, then mode-specific functions are optimized, but the operation time increases due to users needing to locate numeric keys at different positions
Solution Approach 1:
The numeric keys are pre-positioned at a fixed location on the touch-panel display that remains consistent across all operational modes. This preliminary positioning decision eliminates the need for users to search for keys when switching modes, thereby reducing operation time while still allowing the rest of the screen image to be optimized for each specific mode.
3Device complexity
If numeric keys are repositioned for each operational mode, then mode-specific layout optimization is achieved, but user confusion increases leading to potential erroneous operations
Solution Approach 1:
While the overall screen image is optimized differently for each operational mode, the numeric key input area maintains a consistent local quality (position and arrangement) across all modes. This localized consistency provides users with a reliable reference point, reducing confusion and preventing erroneous operations despite the varying layouts of other screen elements.

AI summary
On a touch-panel display of an image forming apparatus, which is divided to five areas, that is, a system area, a function selection area, a preview area, an action panel area and a task trigger area, pieces of information are displayed. Even if an operational mode is switched, the same or similar information is always displayed in the area arranged at the same position. In addition, when an input of a numerical value is requested, a group of keys of the same arrangement is displayed at the same position on the touch-panel display, regardless of the operational mode.
