Dynamic Message Display Time Management in Image Forming Apparatuses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses, messages displayed on operation screens for assisting user operations are often deleted after a constant predetermined time period, which can lead to inconvenience for users who may not read the messages within this time or have them displayed unnecessarily once read.
Innovation Solution
A display control device that manages and sets display time periods for messages based on user operations, allowing messages to be automatically deleted when the user is confirmed to have read them, thereby preventing prolonged or missed message displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a constant display time period is used for messages, then the display control is simple, but users may not read the message within the time period or may continue to display the message after reading
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static constant display time period to a dynamic display time management system. The management unit dynamically adjusts display time periods based on user operations detected by the detection unit, allowing the display time to change according to actual user behavior patterns rather than following a fixed schedule.
Solution Approach 2:
The patent implements feedback by using the detection unit to monitor user operations and feed this information back to the management unit. The management unit then adjusts the display time period based on this feedback, creating a closed-loop system that adapts to user needs and prevents messages from being displayed unnecessarily after reading.
2Device complexity
If a constant display time period is used, then the control mechanism is simple, but user inconvenience increases when messages are not read within the time period
Solution Approach 1:
The patent applies self-service by enabling the system to automatically manage and adjust display time periods based on detected user operations, eliminating the need for manual user intervention to control message display timing. The system serves itself by autonomously detecting user behavior and adapting display parameters accordingly.
3Ease of manufacture
If messages are displayed for a fixed time period, then the display control is straightforward, but messages may remain displayed after users have read them
Solution Approach 1:
The patent applies preliminary action by having the detection unit continuously monitor user operations in advance, and the management unit prepare to adjust display time periods based on predicted user needs. This proactive approach allows the system to anticipate when users have read messages and adjust display timing accordingly, preventing unnecessary continuation of message display.

AI summary
A display control device includes: a management unit that manages a display time period when displaying each of a plurality of messages on a display device for each user; a setting unit that sets the display time period on the basis of an operation of a user; and a control unit that controls display of the message on the basis of the display time period managed by the management unit.
