Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis is employed to locate faults, then engineers can utilize their expertise to analyze alarm information, but the fault location time becomes excessively long and costs increase
Solution Approach 1:
The patent replaces the manual mechanical analysis process with an automated computer-based system. The fault location apparatus automatically collects alarm information, constructs dependency graphs, and identifies faulty FRUs through algorithmic processing, eliminating the time-consuming manual analysis while maintaining or improving accuracy through systematic computation.
Solution Approach 2:
The system enables self-diagnosis by automatically analyzing alarm information and identifying faults without requiring engineer intervention. The fault location apparatus performs self-service fault detection by processing alarm data, constructing dependency relationships, and autonomously determining the location of faulty FRUs.
2Measurement precision
If engineers manually analyze complex alarm information and circuit relationships, then fault location accuracy can be maintained, but the technical expertise requirement and operational complexity increase
Solution Approach 1:
The patent replaces complex manual analysis operations with automated computational processes. The system automatically collects alarm information, constructs dependency graphs representing circuit relationships, and identifies faults through algorithmic processing, eliminating the need for engineers to manually analyze complex relationships while maintaining accuracy.
Solution Approach 2:
The patent introduces a fault location apparatus as an intermediary between alarm information and fault identification. This intermediary automatically processes alarm data, constructs dependency relationships, and translates complex circuit relationships into identifiable fault locations, simplifying the operation for users.
3Productivity
If traditional fault location methods are used, then the process can be completed with basic tools, but the restoration time remains prolonged due to inefficient fault identification
Solution Approach 1:
The patent replaces traditional manual fault identification methods with automated computational processing. The fault location apparatus rapidly analyzes alarm information, constructs dependency graphs, and identifies faulty FRUs through algorithmic processing, dramatically improving identification efficiency and reducing restoration time.
Solution Approach 2:
The system performs preliminary fault identification automatically before engineer intervention is needed. By pre-processing alarm information and identifying potential faulty FRUs through automated analysis, the system prepares fault location results in advance, reducing the overall restoration time when faults occur.
