Solution Overview
Problem
Traditional error detection and mitigation approaches in systems often require redundant hardware and processing, leading to reduced capability for non-error detection or safety-related tasks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional error detection and mitigation approaches are used, then system safety is improved, but device complexity and resource consumption increase due to redundant hardware and processing
Solution Approach 1:
The patent segments the system into safety-critical and non-safety-critical components, allowing error handling to be applied selectively. By classifying modules and processes into safety and non-safety categories, the system can apply rigorous error detection and mitigation only where necessary, reducing overall hardware redundancy and processing overhead while maintaining safety where required.
Solution Approach 2:
The patent implements local quality by applying different error handling strategies to different parts of the system based on their safety classification. Safety-critical modules receive comprehensive error detection and mitigation, while non-safety modules use simplified or no error handling, optimizing resource allocation and reducing overall system complexity.
2Reliability
If comprehensive error detection and mitigation is implemented, then system reliability is improved, but productivity decreases due to reduced capability for non-error detection or safety-related tasks
Solution Approach 1:
By segmenting error handling resources according to safety criticality, the system maintains high reliability for safety functions while freeing computational resources for non-safety tasks. This selective approach ensures that comprehensive error detection is applied only where it impacts safety, allowing other system capabilities to operate with full productivity.
Solution Approach 2:
The patent applies partial error detection action by implementing error handling only to the extent necessary for safety-critical functions. Rather than applying uniform comprehensive error detection across all system operations, the patent uses error detection selectively based on safety classification, optimizing the balance between reliability and productivity.
3Reliability
If all operations are stopped upon error detection, then system safety is improved, but loss of time increases due to shutdown of unaffected operations
Solution Approach 1:
The patent segments operational response based on error location and safety classification. When an error is detected, the system identifies whether it affects safety-critical or non-safety-critical functions and stops only the affected segment. This allows unaffected operations to continue running, minimizing operational downtime while maintaining safety through targeted shutdowns of only necessary components.
Solution Approach 2:
The patent implements dynamic error response by continuously monitoring error impact and adjusting operational status in real-time. Rather than static all-or-nothing shutdowns, the system dynamically determines which operations to continue or stop based on real-time safety assessment, allowing flexible maintenance of safe operations while minimizing unnecessary downtime.

AI summary
Embodiments of the present disclosure relate to a method of detecting an error corresponding to a monitored system. The method may additionally include determining whether the error corresponds to a safety module associated with the monitored system that may have one or more operations that are deemed to affect safety or whether the error corresponds to a safety process associated with the monitored system that may have one or more operations that are deemed to affect safety. In some embodiments, the method may additionally include determining whether to continue operations of the monitored system, where the determination may be based at least on whether the error may correspond to a safety module associated with the monitored system or whether the error corresponds to a safety process associated with the monitored system.
