Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional configuration management systems for nuclear power plants face difficulties in managing and associating vast amounts of design basis information, leading to inefficiencies in design changes, operations, and maintenance due to fragmented and dispersed documentation.
Innovation Solution
A data-based design basis management system that utilizes a database to store and organize design basis information into categories with associative relationships, allowing users to intuitively access and manage design requirements, specifications, and physical structure data through a user interface, enabling hierarchical tracing of design basis associations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If design basis information is managed using traditional fragmented documentation methods, then information completeness is maintained, but information accessibility and retrieval efficiency deteriorate
Solution Approach 1:
The patent merges fragmented design basis information from multiple categories (design requirements, design basis specifications, structure/system/component specifications, supporting operation information, design parameters, supporting design information, and physical structure/system/component specification data) into a single integrated database. This consolidation allows users to access all associated design basis information through one unified interface, eliminating the need to search through scattered documents and significantly improving information accessibility while reducing retrieval time.
Solution Approach 2:
The patent introduces an associative relationship module that acts as an intermediary between different categories of design basis information. This module establishes and manages links between related information across categories, enabling users to automatically trace and access associated design basis from one category to another. The intermediary mechanism facilitates seamless navigation and retrieval of connected information without requiring manual searching through multiple document sources.
2Ease of operation
If design basis documents are created and used without associative relationships, then document creation simplicity is maintained, but the ability to review and trace design basis deteriorates
Solution Approach 1:
The patent segments the management of design basis information into distinct functional modules: a database for storing information, an associative relationship module for managing links, and a user interface for interaction. This segmentation allows the system to handle complex associative relationships in a structured manner while presenting a simplified interface to users. Each module performs a specific function, making the overall complex system manageable and maintainable.
Solution Approach 2:
The patent replaces manual mechanical methods of tracking design basis associations (such as cross-referencing through printed documents or manual file linking) with an automated computer-based system. The associative relationship module automatically establishes and maintains links between design basis information across categories through digital data structures, eliminating the need for physical document manipulation and providing automated retrieval capabilities that simplify user operations despite the underlying system complexity.
3Productivity
If vast amounts of design basis information are managed in printouts, then information completeness is preserved, but configuration management efficiency deteriorates
Solution Approach 1:
The patent creates a digital copy of all design basis information from physical printouts and scattered documents, storing it in a structured database format. This digital replication preserves the complete information content while enabling efficient computer-based management, search, and retrieval operations. The digital copy can be easily accessed, displayed, and manipulated without the physical constraints of paper documents, significantly improving configuration management productivity despite the large volume of information.
Solution Approach 2:
The patent transforms the management of design basis information from a two-dimensional physical space (paper printouts) to a multi-dimensional digital space with hierarchical categorization and associative relationships. Information is organized across multiple dimensions including category hierarchies (from design requirements down to physical specifications), associative links between related items, and searchable metadata. This dimensional transformation allows the system to handle vast amounts of information efficiently through digital indexing and retrieval mechanisms, improving productivity while managing large information volumes.
