FT Diagram Generation Aid Device Markup Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The generation and modification of Fault Tree (FT) diagrams using spreadsheet programs like Excel are inefficient, requiring extensive knowledge and labor for editing, especially when adding, deleting, or modifying events.
Innovation Solution
A device and program that import and export FT diagrams from spreadsheet programs to markup language, allowing for easy editing of the tree structure, including functions for importing connection relationships, editing events, analyzing events, verifying consistency, and exporting modified diagrams back to the spreadsheet format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If FT diagrams are generated and edited using spreadsheet programs, then the diagrams can be created with high diffusion rate and accessibility, but the editing process becomes inefficient and labor-intensive
Solution Approach 1:
The patent introduces a conversion program that acts as an intermediary between spreadsheet programs and markup language editors. This mediator converts FT diagrams from spreadsheet format to markup language format, enabling efficient editing while maintaining accessibility. The conversion program translates the visual spreadsheet representation into a structured markup format that supports easier modification and management.
2Adaptability or versatility
If FT diagrams are generated using spreadsheet programs, then they can be easily shared among engineers, but modification and maintenance become complex and time-consuming
Solution Approach 1:
The patent changes the data format parameter of FT diagrams from spreadsheet format to markup language format. This parameter change enables more efficient storage, editing, and management of the diagram data. The markup language provides a structured representation that facilitates automated processing, version control, and easier modification compared to spreadsheet formats.
3Reliability
If FT diagrams are created with extensive knowledge and specialization requirements, then the diagrams maintain high reliability and accuracy, but the generation process becomes complex and difficult
Solution Approach 1:
The patent implements automated functions that enable the FT diagram system to serve itself. The conversion program automatically translates spreadsheet data to markup language, and the system provides automated validation and consistency checking. This self-service capability reduces the need for manual intervention and specialized knowledge during the editing and maintenance phases.
Data Source
AI summary
An FT diagram aid device is provided with an import portion for obtaining a connection relationship of ruled lines and character strings from first data which is data of an FT diagram expressing a tree structure by the ruled lines and the character strings on a sheet of a spreadsheet program, acquiring an event included in the FT diagram and a connection relationship between events from an obtained connection relationship of the ruled lines and the character strings, and generating second data describing the tree structure of the FT diagram in a markup language based on the same and an editing portion for editing the second data to generate third data describing the tree structure of the edited FT diagram in the markup language.
