Maintenance Information Sharing System for Plant Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In plant maintenance, sharing maintenance information is challenging due to the inability to represent complex skills through images alone, especially when text information and data from sensors, measurers, or control devices are involved, leading to time-consuming searches for relevant maintenance records.
Innovation Solution
A maintenance information sharing system that includes a maintenance record obtainer, storage, generator, searcher, and provider, allowing for the accumulation, storage, and retrieval of maintenance information associated with identification data, enabling efficient sharing and retrieval of maintenance records across distant locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If maintenance information is stored only as image files from video call recordings, then visual maintenance skills can be shared, but text information and sensor data cannot be properly represented
Solution Approach 1:
The maintenance information is segmented into multiple types: image data (video recordings), text data (work diaries, repair records), and sensor data (measurement values). Each type is stored separately but associated through identification information, allowing comprehensive representation of different maintenance skill aspects that cannot be captured by images alone.
Solution Approach 2:
The system creates a composite information structure that combines multiple data types (images, text, sensor readings) into a unified maintenance record. This composite approach enables the system to represent complex maintenance skills that involve both visual procedures and numerical/textual data from sensors and measurement devices.
2Ease of manufacture
If maintenance records are stored with only recording date and file name, then simple files can be managed, but searching for specific maintenance information becomes time-consuming
Solution Approach 1:
Identification information is preliminarily assigned to each maintenance record at the time of storage. This pre-tagging with searchable identifiers (beyond just file names and dates) enables rapid retrieval later without requiring manual searching through numerous files, thus reducing search time while maintaining storage simplicity.
3Reliability
If multiple maintenance items are performed on the same device, then comprehensive maintenance can be achieved, but finding relevant records becomes more difficult
Solution Approach 1:
The identification information structure is designed to be universal and multi-functional, capable of representing a device and its multiple maintenance items in a unified manner. This allows the system to organize and retrieve records for devices with multiple maintenance items without increasing organizational complexity, maintaining both completeness and manageability.

AI summary
A maintenance information sharing device includes a maintenance record obtainer configured to obtain a maintenance record of a maintenance target, a maintenance record storage configured to associate the maintenance record obtained by the maintenance record obtainer with identification information for identifying the maintenance target, the maintenance record storage storing the maintenance record associated with the identification information, a maintenance information generator configured to generate maintenance information based on the maintenance record associated with the identification information and stored by the maintenance record storage, a maintenance information storage which stores the maintenance information generated by the maintenance information generator, a searcher configured to search the maintenance information stored by the maintenance information storage based on the identification information, and a maintenance information provider configured to provide the maintenance information searched by the searcher.
