Dynamic Display Unit for Image Forming Apparatus Operational Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses often fail to allow users to easily set desired operational conditions without errors or omissions, especially when switching between operational modes, leading to incorrect or forgotten settings.
Innovation Solution
An image forming apparatus with a reading unit, image forming unit, operating unit, input unit, and display unit that displays operable operational conditions based on user input and document content, allowing users to select and set conditions without returning to the original mode, and enables changing set conditions without leaving the current mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user selects a display screen with fewer display items, then the display is simpler and easier to view, but the user cannot set all desired operational conditions and may make mistakes
Solution Approach 1:
The display unit dynamically changes the number and type of display items based on the operational mode and user's progress in setting conditions. The display transitions from showing all operational conditions initially to showing only unset conditions later, adapting to the user's needs at different stages
Solution Approach 2:
The operational conditions are segmented into two categories: already-set conditions and unset conditions. The display unit separately manages these segments, initially displaying all conditions and then focusing only on remaining unset conditions to guide the user systematically
2Stability of the object's composition
If the user must return to the original set mode screen to change operational conditions, then the system maintains strict mode separation, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The display unit serves multiple functions: it displays operational conditions in the current mode, shows already-set conditions from other modes, and provides access to change settings without returning to the original mode. This multi-functionality resolves the contradiction by maintaining mode integrity while enabling efficient setting changes
3Loss of information
If all operational conditions are displayed at once, then the user has complete information, but it becomes difficult to identify which conditions need to be set
Solution Approach 1:
The display unit dynamically adapts its content based on the user's progress. Initially, all operational conditions are displayed to provide complete information. As the user sets conditions, the display automatically updates to show only the remaining unset conditions, making it easy to identify what needs attention next

AI summary
An image forming apparatus determines if a support function key is pressed down or not. When it is determined that the support function key is pressed down, the image forming apparatus determines if the read document is a one side document or a both-side document. Then the document is read and operable operational conditions are selected based on the read document and the information about an intended use that is inputted by a user. The selected operational conditions are displayed on an operating unit for each operational condition. As a result, it is possible to provide an image forming apparatus wherein the user can set a desired operational condition easily suitable for the user's intended use without omission and fail.
