Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fault-tolerant systems fail to consider the identification and isolation of irrelevant components, leading to potential single-point failures due to imperfect fault coverage, which deteriorates system reliability.
Innovation Solution
A fault-tolerant system and method that includes system failure logic and irrelevant component coverage means to identify and isolate irrelevant components based on system failure logic, preventing future uncovered failures by editing and processing system failure logic and performing irrelevant component isolation.

Engineering Contradiction Analysis
1Reliability
If conventional coverage model only identifies and isolates faulty components, then the identification process is simple, but system reliability deteriorates due to single-point failures from irrelevant components
Solution Approach 1:
The patent segments the component identification process into two distinct segments: (1) identification of faulty components through conventional fault detection, and (2) identification of irrelevant components through failure logic analysis. This segmentation allows the system to handle both faulty and irrelevant components separately, improving reliability without overwhelming complexity.
Solution Approach 2:
The patent applies preliminary action by pre-editing the failure logic to identify irrelevant components before they can cause single-point failures. The failure logic is prepared in advance to recognize which components, if failed, would not affect system functionality, allowing proactive isolation of these components before failures occur.
2Reliability
If irrelevant components are not isolated, then the system operation is simple, but uncovered faults in irrelevant components lead to single-point failures
Solution Approach 1:
The system performs self-service by automatically analyzing failure logic and identifying irrelevant components without requiring manual intervention. The failure logic editing mechanism autonomously determines which components are irrelevant and should be isolated, making the reliability improvement process self-executing and easy to operate.
Solution Approach 2:
The patent implements feedback by continuously monitoring component status and comparing it against the edited failure logic. When a component is identified as irrelevant through the failure logic analysis, the system provides feedback to isolate that component, creating a closed-loop system that automatically maintains reliability without increasing operational burden.
3Reliability
If system failure logic is edited to identify irrelevant components, then future uncovered failures are prevented, but the initial system setup becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-editing the failure logic during system configuration to include identification rules for irrelevant components. This preliminary setup, while initially more complex, establishes an automated mechanism that prevents future uncovered failures without requiring ongoing manual configuration or intervention.
