Integrated Drawing for Common Cause Failure Tracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual identification of fault propagation paths and common cause failures in nuclear power plants is error-prone and inefficient, especially as systems become complex, and existing technologies lack effective management of design changes and device failures.
Innovation Solution
An integrated drawing method that automatically detects and analyzes common cause failures by hierarchically dividing and connecting entities with the same attributes in design drawings, generating a hierarchical structure for accurate fault propagation path tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual identification of fault propagation paths and common cause failures is performed, then flexibility and adaptability are maintained, but human error increases and efficiency decreases as system complexity grows
Solution Approach 1:
The patent replaces manual mechanical tracing methods with an automated computer-based system that uses algorithms to trace fault propagation paths and identify common cause failures. The system automatically processes design drawings, fault tree diagrams, and block diagrams to detect faults and propagate failure information without human intervention, thereby eliminating human error and significantly improving efficiency.
Solution Approach 2:
The system enables self-service by allowing the computer to autonomously perform fault propagation path tracing and common cause failure identification. The automated system processes design data, detects faults, and generates analysis results independently, reducing reliance on manual human analysis and improving both reliability and productivity.
2Adaptability or versatility
If design drawing content is changed, deleted, and/or added, then design updates are achieved, but manual re-tracing of fault propagation paths causes great manpower loss
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors design drawing changes and automatically updates fault propagation path analysis. When design changes occur, the system detects modifications, re-traces affected fault paths, and updates common cause failure identification without requiring manual re-analysis, thereby eliminating repeated manpower loss while maintaining adaptability to design changes.
3Loss of information
If existing common cause failure tracing technology is used, then initial fault analysis is provided, but effective management of device failures and design changes is not achieved
Solution Approach 1:
The patent creates a universal system that handles multiple functions including fault detection, fault propagation path tracing, common cause failure identification, and management of design changes and device failures. The system integrates these previously separate functions into a single automated platform that provides comprehensive failure information management and improves ease of operation through unified access and automated processing.

AI summary
Provided is an integrated drawing producing method for common cause tracing. The integrated drawing producing method includes: distinguishing shapes of entities in at least one design drawing and assigning an attribute to each of distinguished entities; synthesizing the entities assigned the attributes in the at least one design drawing in units of a system where a common cause is to be traced; and generating an integrated drawing with a hierarchical structure by horizontally or vertically interconnecting the entities assigned the same attribute in the at least one design drawing.
