Equipment Restoration Guidance With Priority-Based Work Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an abnormality occurs in automatically operated equipment, it is challenging for inexperienced workers to determine the necessary work items and procedures for restoration, especially when the equipment state changes during the restoration process, leading to complicated processing.
Innovation Solution
A device and method that store work items and priority information for each potential abnormality location, generate restoration assist information based on priority, and update this information when equipment states change, providing a clear order of execution for restoration work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker determines work items and procedures based on personal knowledge and experience, then the restoration work can be performed with simple procedures, but inexperienced workers cannot properly determine the necessary work items and procedures
Solution Approach 1:
The system enables self-service by automatically generating restoration work information based on abnormality detection, eliminating the need for workers to rely on personal knowledge and experience. The system serves itself by autonomously determining work items and procedures through automated information processing.
Solution Approach 2:
The patent replaces the mechanical system of human knowledge and experience with an automated information processing system. The control device substitutes human judgment with automated generation of restoration work information based on detected abnormality data.
2Adaptability or versatility
If the equipment state changes during restoration work, then the system can adapt to new abnormalities, but the processing becomes complicated as workers must rearrange work items and procedures
Solution Approach 1:
The system dynamically adjusts restoration work information when equipment state changes occur during restoration. The control device updates work items and procedures in real-time based on new abnormality detections, making the system flexible and adaptive without requiring manual rearrangement by workers.
Solution Approach 2:
The system implements feedback by continuously monitoring equipment state during restoration work and automatically updating restoration work information when changes are detected. This closed-loop approach ensures the system adapts to new conditions while maintaining simple processing for workers.
3Reliability
If comprehensive restoration information is provided to guide workers through all possible work items, then inexperienced workers can perform restoration properly, but the information becomes overwhelming and difficult to process
Solution Approach 1:
The system segments restoration work information into prioritized lists based on abnormality severity and equipment importance. Instead of presenting all possible work items simultaneously, the control device divides information into manageable, ordered sequences that guide workers through essential tasks first.
Solution Approach 2:
The patent applies local quality by providing different levels of restoration information guidance to different users or situations. The system tailors the detail and scope of restoration work information based on specific abnormality conditions and equipment contexts, delivering appropriate granularity rather than uniform comprehensive information.
Data Source
AI summary
A restoration work information storage unit stores a work item for restoration that is set for each location at which an abnormality is expected to occur in equipment to be managed, and priority information indicating a priority of execution for each of the work items. Upon detecting that an abnormality has occurred in the equipment and an operation of the equipment has been stopped, a restoration assist information generation unit generates restoration assist information, in which the work items for restoring the equipment are arranged in the order of execution according to the priority information, based on information of a location at which the abnormality has occurred. Upon detecting that a state of any location in the equipment has changed before a restoration work based on the restoration assist information is completed, a restoration assist information update unit updates the restoration assist information.
