Work Assistance System Attribute-Based Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In device maintenance, existing systems face inefficiencies and errors due to the need to manage and process large amounts of work data from multiple field devices, often with overlapping identification information, leading to increased processing loads and storage capacity issues, and difficulties in distinguishing between devices.
Innovation Solution
A work assistance system that stores work data for each device and allows setting of attributes, enabling the extraction and display of only relevant work data, reducing the need to process and store unnecessary data, thereby improving efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all work data from multiple field devices is incorporated into the management work tool, then complete work data is available for management, but the amount of data becomes significant and difficult to search, leading to errors and low work efficiency
Solution Approach 1:
The patent extracts and displays only the necessary work data for management purposes rather than incorporating all work data from multiple field devices. The management work terminal apparatus selectively retrieves and presents relevant work data, separating essential information from the complete dataset to improve both accuracy and efficiency.
2Reliability
If all work data from multiple field devices is incorporated into the management work tool, then complete work data is available for management, but processing load and storage requirements increase significantly
Solution Approach 1:
The system extracts only the necessary work data required for management from the complete dataset stored across multiple field devices. The management work terminal apparatus retrieves selective information rather than processing all available data, thereby maintaining data completeness for management needs while significantly reducing processing load and storage requirements at the management terminal.
3Ease of manufacture
If field devices have overlapping identification information, then device identification becomes ambiguous, but maintaining simple device identifiers is preferred
Solution Approach 1:
The patent resolves ambiguous device identification by adding another dimension to the identification system. Instead of relying solely on simple device identifiers that may overlap, the system incorporates additional distinguishing attributes such as work data characteristics, device location, or operational parameters, enabling unique identification of each field device while maintaining simple base identifiers.
