P&ID Element Group Extraction for Batch Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing P&IDs require significant manual effort and are prone to human error, especially in large-scale systems, leading to inefficiencies and increased error rates in extracting and correcting element groups.
Innovation Solution
An information processing apparatus and method that automatically searches and displays element groups matching a user-selected search group, allowing batch processing of identical groups, hierarchical organization, and efficient extraction of defective elements, with features for distinguishing and correcting partially different groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual extraction and correction of element groups is performed, then flexibility in handling individual cases is maintained, but the number of person-hours required increases significantly and human error increases
Solution Approach 1:
The system performs automatic extraction and correction of element groups without requiring manual intervention for each group. The apparatus autonomously identifies matching element groups based on search criteria, extracts them, and applies corrections, thereby eliminating human error while reducing the time required for processing large numbers of element groups
Solution Approach 2:
The patent replaces the manual mechanical process of extracting and correcting element groups with an automated information processing system. The processor automatically searches for matching element groups based on search conditions, retrieves them from the drawing data, and applies corrections, substituting human operators with an automated computational system that processes data faster and more accurately
2Productivity
If automatic search and display of matching element groups is implemented, then productivity increases and person-hours are reduced, but the complexity of the processing system increases
Solution Approach 1:
The information processing apparatus is designed to perform multiple functions: searching for element groups based on various criteria, displaying matching groups on the display device, extracting selected groups, and applying corrections. This multi-functional design consolidates what would otherwise require multiple separate tools into a single system, managing complexity while delivering comprehensive automated processing capabilities
Solution Approach 2:
The system introduces an intermediate processing layer between the drawing data and the user. The processor acts as an intermediary that automatically searches through the drawing data, identifies matching element groups, and presents them for selection and correction. This intermediary layer handles the complex search and matching logic, shielding the user from complexity while maintaining high productivity
3Productivity
If batch processing of identical element groups is enabled, then efficiency in correcting multiple groups improves, but the ability to handle partially different groups appropriately becomes more difficult
Solution Approach 1:
The system applies different processing qualities to different element groups based on their characteristics. Matching element groups that are identical are processed in batch with automatic correction, while partially different groups are identified and handled separately. This local differentiation allows the system to optimize for efficiency where applicable while maintaining adaptability for cases requiring individual attention
Solution Approach 2:
The patent segments element groups into distinct categories: fully matching groups that can be processed in batch, and partially different groups that require separate handling. This segmentation allows the system to apply batch processing efficiency to appropriate groups while maintaining the ability to handle variations individually, balancing productivity and adaptability

AI summary
An information processing apparatus including a processor that receives a selection from a user of a region, in a drawing in which elements are indicated by graphics, that contains the graphics, extracts from the drawing one or more first elements, indicated by the graphics, that are completely contained within the region for which the selection is received, extracts from the drawing one or more second elements, indicated by the graphics, that intersect a boundary of the region for which the selection is received, extracts a third element from the one or more second elements based on a positional relationship between the graphics indicating the one or more second elements and the boundary, and stores a set of elements including the one or more first elements and the third element in a storage as an element group selected by the user.
