Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing facility diagnosis support apparatus is unable to diagnose abnormalities when past operation information is not available.
Innovation Solution
A diagnosis support apparatus that stores operation information in association with material positions and includes an extraction unit to retrieve operation information from a designated range, allowing for efficient diagnosis even without past operation data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If diagnosis is performed by comparison with past operation information, then diagnosis accuracy is improved, but the system cannot diagnose when past operation information is not present
Solution Approach 1:
The patent segments operation information by material position into multiple storage units, allowing the system to retrieve relevant operational data from specific position-based segments even when complete historical data is unavailable. This enables diagnosis to proceed with partial, position-specific information.
Solution Approach 2:
The patent introduces position information as an intermediary index that connects current abnormality detection with relevant past operation information. By using position as a mediator, the system can retrieve comparable operational data from other materials that passed through the same position, enabling diagnosis without requiring complete historical data for the specific material.
2Reliability
If all operation information is stored for every process, then complete diagnostic data is available, but data retrieval becomes inefficient
Solution Approach 1:
The patent divides operation information storage into position-based segments, where each storage unit holds data specific to a particular material position. This segmentation allows the extraction unit to retrieve only the relevant position-specific data needed for diagnosis, rather than searching through all operation information across all processes and all materials.
Solution Approach 2:
The patent applies local quality by organizing storage units to reflect the spatial structure of the manufacturing facility. Each storage unit is tailored to store operation information for a specific position, ensuring that the data structure matches the diagnostic needs for that particular location, thereby enabling efficient targeted retrieval.

AI summary
There is provided a manufacturing facility diagnosis support apparatus that can support efficient diagnosis of a manufacturing facility even when past operation information on the manufacturing facility is not present. The diagnosis support apparatus includes a storage unit configured to store operation information in each of processes of a manufacturing facility for processing a material and information on a position of the material in association with each other, and an extraction unit configured to extract, when a range including the position of the material is designated, operation information changed at a position corresponding to the designated range, from the operation information stored in the storage unit. According to the diagnosis support apparatus, it is possible to support efficient diagnosis of the manufacturing facility even when the past operation information on the manufacturing facility is not present.
