Image Defect Diagnosis With User-Prioritized Maintenance Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic systems for image forming apparatuses struggle to reduce engineer visits during maintenance, despite improving the accuracy of identifying components to be replaced, as they do not effectively prioritize maintenance tasks based on user capabilities.
Innovation Solution
A diagnostic system that analyzes images for defects, identifies maintenance candidates, and outputs a diagnosis result prioritizing tasks based on whether the user or engineer can execute them, using a display order determined by defect severity and difficulty level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the diagnostic system provides detailed component replacement information based on defect analysis, then the accuracy of identifying components to be replaced is improved, but the number of engineer visits to users is not sufficiently reduced
Solution Approach 1:
The diagnostic system enables users to perform maintenance themselves by providing prioritized guidance. The system analyzes defect images, identifies candidate components, and ranks them by user-executability, allowing users to handle simple maintenance tasks without engineer intervention, thus reducing visit frequency while maintaining accurate component identification
Solution Approach 2:
The maintenance tasks are segmented into different priority levels based on user capability. The system divides candidate components into those users can service themselves and those requiring engineers, presenting them in prioritized order. This segmentation enables users to independently handle appropriate tasks while engineers focus on complex issues
2Adaptability or versatility
If the diagnostic system provides all candidate components for maintenance without prioritization, then comprehensive maintenance coverage is achieved, but user execution capability is not considered leading to unnecessary engineer visits
Solution Approach 1:
The diagnostic system dynamically prioritizes maintenance candidates based on user capability and task complexity. Rather than providing a static list, the system adapts the presentation order according to whether users can execute each maintenance task, placing user-executable tasks first and engineer-required tasks later, thus making comprehensive maintenance coverage operationally efficient
Data Source
AI summary
A diagnostic system includes one or more processors configured to: acquire an image formed by an image forming apparatus; detect a defect in the image by analyzing the acquired image; identify candidates for maintenance related to the detected defect; and output a diagnosis result indicating the candidates for the maintenance in an order that is determined depending on whether a user of the image forming apparatus is enabled to execute the maintenance.
