Equipment Recovery Guidance With Dynamic Work Order Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inequipped workers face difficulties in determining necessary work items and procedures for equipment restoration, especially when equipment states change during restoration, leading to complex processing.
Innovation Solution
A device connected to a tool changer for automatically operated equipment generates restoration work assist information by prioritizing and rearranging work items based on sensor data and pre-stored information, providing a display for workers to follow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker with little experience performs restoration work based on personal knowledge, then the worker can perform the work independently, but the accuracy of determining necessary work items and procedures deteriorates
Solution Approach 1:
An information processing device acts as an intermediary between the worker and the equipment restoration process. The device receives operation state information from sensors, determines appropriate work items and procedures, and provides guidance information to the worker. This mediator ensures accurate restoration guidance even for inexperienced workers without requiring them to have extensive personal knowledge.
2Adaptability or versatility
If the worker manually determines and rearranges work items when equipment state changes during restoration, then the work can adapt to new conditions, but the processing complexity increases
Solution Approach 1:
The system implements continuous feedback by monitoring operation state information from sensors during the restoration process. When equipment state changes are detected, the information processing device automatically re-determines work items and procedures based on the new state, providing updated guidance information. This feedback mechanism enables automatic adaptation to changing conditions without increasing processing complexity for the worker.
Solution Approach 2:
The information processing device performs self-service by automatically monitoring equipment state changes and generating appropriate restoration guidance without requiring manual intervention from the worker. The system autonomously determines work items, procedures, and their sequences based on sensor data, reducing the cognitive burden on the worker while maintaining high adaptability.
3Reliability
If comprehensive work items and procedures are provided for all possible equipment states, then complete coverage is achieved, but the information volume and processing load increase
Solution Approach 1:
The restoration guidance information is segmented into distinct work items and procedures, each associated with specific equipment states. The information processing device selectively provides only the relevant segmented information based on the current operation state, rather than presenting all possible restoration procedures. This segmentation maintains complete coverage while reducing information volume to what is actually needed at each stage.
Solution Approach 2:
The system provides locally optimized information by tailoring the restoration guidance to the specific equipment state and location. Rather than providing uniform comprehensive information for all scenarios, the device delivers targeted work items and procedures relevant to the current abnormal state, ensuring complete coverage for each specific condition while minimizing overall information volume.

AI summary
A device for assisting equipment restoration work (30) includes a restoration work information storage unit (31), a restoration assist information generation unit (332), and a restoration assist information update unit (335). The restoration work information storage unit (31) 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, the restoration assist information generation unit (332) 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, the restoration assist information update unit (335) updates the restoration assist information based on information of the location at which the change has occurred.
