Image Forming Apparatus Movie Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatus maintenance procedures face issues when a job is started during a movie presentation, leading to increased CPU processing load and potential delays, with previous solutions causing a sudden drop in frame rate, resulting in an unpleasant user experience.
Innovation Solution
The apparatus plays multiple sub-movies sequentially as a single movie, using different frame rates and a control unit to switch between them based on job execution status, ensuring seamless playback and reduced CPU load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the frame rate is lowered when a job is started during movie playback, then the CPU processing load is reduced, but the movie playback quality deteriorates and users feel strangeness
Solution Approach 1:
The system prepares multiple versions of the movie in advance: a first movie with a first frame rate and a second movie with a second frame rate. This preliminary preparation allows the system to switch between versions based on CPU load conditions without degrading playback quality during normal operation.
Solution Approach 2:
The system dynamically selects which movie version to play based on real-time CPU processing load conditions. When CPU load exceeds a threshold, it switches to the second movie with lower frame rate; when load is normal, it plays the first movie with higher frame rate. This dynamic adaptation resolves the contradiction between maintaining playback quality and reducing CPU load.
2Productivity
If a job is started during movie playback, then productivity is improved by processing jobs, but the movie update and job execution may be delayed due to increased CPU processing load
Solution Approach 1:
The system prepares multiple movie versions in advance with different frame rates, so when a job needs to be processed, it can immediately switch to the pre-prepared second movie with lower frame rate without causing delays in job execution or movie updates.
Solution Approach 2:
The system changes the frame rate parameter of the movie based on CPU load conditions. When a job is started and CPU load increases, the system switches to a movie version with a lower frame rate parameter, allowing job processing to proceed without delaying movie updates.
3Power
If the frame rate is lowered suddenly when a job starts, then CPU processing load is reduced, but user experience deteriorates due to sudden frame rate change
Solution Approach 1:
The system prepares both movie versions in advance, so the transition between frame rates is smooth and pre-planned rather than sudden. This preliminary preparation prevents the harmful effect of sudden frame rate changes on user experience.
Solution Approach 2:
The system dynamically switches between movie versions based on CPU load conditions, but the switch is managed smoothly by having both versions ready. This dynamic approach allows CPU load to be reduced without creating the harmful effect of sudden, jarring frame rate changes that would degrade user experience.

AI summary
An image forming apparatus plays a movie representing operation procedures to be performed to make maintenance on the image forming apparatus. In a case where start of a job is detected and an operation by a user is detected, the image forming apparatus plays the movie of which frame rate is lowered.
