Image Forming Apparatus Maintenance Video Replay Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in performing maintenance operations on image forming apparatuses as existing video guides often require users to look away from the operation, leading to confusion when the video proceeds without their intention, and it is challenging to replay specific procedures.
Innovation Solution
An image forming apparatus with a playing unit that combines sub-movies for maintenance procedures and a display unit that shows a replay mark to restart the movie from the beginning of the stopped sub-movie, allowing users to easily replay specific steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single movie is prepared for each maintenance procedure, then the movie can present complete operation procedures, but the user cannot easily replay specific steps without replaying the entire movie
Solution Approach 1:
The maintenance procedure movie is divided into multiple sub-movies, each representing a specific operation step. When the user stops the movie at a particular point, the system identifies the corresponding sub-movie and allows replay from that specific segment rather than the beginning of the entire movie, thus reducing time loss while maintaining complete procedural information
2Productivity
If the movie proceeds automatically through all procedures, then the presentation is continuous, but the user may lose track of the current operation step
Solution Approach 1:
The display unit provides visual feedback by showing a replay mark that indicates the current position in the maintenance procedure. When the user stops the movie, the system displays information about which sub-movie is currently being shown, allowing the user to understand their current operation step and maintain awareness throughout the maintenance process

AI summary
An image forming apparatus combines a plurality of sub-movies representing operation procedures to be performed to perform maintenance on the image forming apparatus and plays the combined sub-movies sequentially as one movie. In response to stopping the movie being played, the image forming apparatus displays a replay mark for use to issue a command to replay the movie from the beginning of a sub-movie corresponding to a position where the movie is stopped.
