Printing System Priority Task Display for Maintenance Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing machine maintenance techniques fail to efficiently guide operators in handling multi-cause errors, as error codes do not distinguish between different procedural requirements for resolving sheet jamming and conveyance issues, leading to inefficient problem-solving during out-of-hours maintenance.
Innovation Solution
A printing system that acquires state information from the printing machine, extracts relevant task information, and calculates a priority order for displaying recovery tasks based on historical data, ensuring that the most efficient procedures are followed for resolving issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only an error code is notified to indicate a problem, then the notification is simple and clear, but the operator cannot determine the specific recovery procedure when multiple causes exist
Solution Approach 1:
The notification is segmented into multiple components: error code, error message, and multiple candidate recovery procedures with priorities. This segmentation allows the system to provide comprehensive information without overwhelming the operator, as each component serves a specific function in the diagnostic and recovery process.
Solution Approach 2:
The system performs preliminary action by pre-registering multiple candidate recovery procedures in advance, associating them with error codes and state information. When an error occurs, the system immediately retrieves and presents these pre-prepared procedures with calculated priorities, eliminating the need for operators to search for solutions manually.
2Adaptability or versatility
If multiple recovery procedures are presented to the operator, then the operator has more options to solve the problem, but the operator may be confused about which procedure to follow first
Solution Approach 1:
Each recovery procedure is assigned local quality in the form of priority information and detailed descriptions tailored to specific error causes. The system presents procedures with varying levels of detail and priority markings, allowing operators to quickly identify the most relevant procedure for the specific error condition they are facing.
Solution Approach 2:
The system provides feedback by calculating and displaying priority orders for multiple recovery procedures based on the specific error code and state information. This feedback mechanism guides operators to follow procedures in the optimal sequence, improving both the efficiency and success rate of problem resolution.
3Productivity
If the system calculates priority order for multiple recovery procedures, then the most efficient procedure is presented first, but additional processing time is required to analyze and rank the procedures
Solution Approach 1:
The system performs preliminary action by pre-registering recovery procedures and their associations with error codes and state information in a database. This pre-processing allows the system to quickly retrieve and rank procedures when errors occur, minimizing the time required for priority calculation during actual problem resolution.
Solution Approach 2:
The system replaces manual analysis and ranking of recovery procedures with automated information processing. The server automatically calculates priority orders based on pre-register d data and error conditions, eliminating the need for operators to manually evaluate multiple procedures and their applicability.
4Measurement precision
If detailed state information is collected and processed, then the system can provide more accurate recovery guidance, but the data processing complexity and storage requirements increase
Solution Approach 1:
The system extracts only the necessary state information and error codes from the printing machine that are relevant to identifying problems and selecting recovery procedures. By extracting and processing only the essential data elements, the system achieves high measurement precision without requiring complex processing of all possible machine parameters.

AI summary
A non-transitory recording medium storing a computer-readable monitoring program presents information regarding a related task for handling a problem of a printing machine in the most efficient order, thus improving work efficiency in handling the problem. The non-transitory recording medium storing the computer-readable monitoring program causes a computer to execute acquiring state information regarding a state of a printing machine, extracting related task information associated with the acquired state information from registered related task information corresponding to the state information, and calculating, in a case where a plurality of pieces of the extracted related task information are present, a priority order in which the pieces of related task information are to be displayed.
