Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional remote data processing methods are used, then system complexity is reduced, but response time to faults increases and reliability decreases
Solution Approach 1:
The system segments data processing functions between edge devices (local processing) and remote systems (cloud processing). Edge devices perform real-time fault detection locally, while remote systems handle non-critical data logging and analysis, enabling rapid local response without requiring complex centralized processing for every data point.
Solution Approach 2:
The system performs preliminary data processing and anomaly detection at the edge before data reaches remote systems. By pre-processing data locally and identifying faults in advance, the system reduces the time required for fault detection and enables immediate local response actions without waiting for remote system analysis.
2Measurement precision
If advanced machine learning algorithms are implemented, then anomaly detection capability improves, but device complexity increases
Solution Approach 1:
The system segments machine learning workloads between edge devices (lightweight models for real-time detection) and remote systems (complex model training and heavy computation). This segmentation enables sophisticated anomaly detection at the edge without requiring full-blown ML infrastructure at every location.
Solution Approach 2:
The system introduces an intermediary layer that manages the complexity of machine learning algorithms. This layer handles model deployment, updating, and coordination between edge devices and remote systems, shielding individual components from the full complexity while enabling advanced anomaly detection capabilities.
3Speed
If real-time data processing is implemented at the edge, then response time improves, but energy consumption increases
Solution Approach 1:
The system implements partial real-time processing at the edge, focusing computational resources only on critical fault detection functions rather than processing all data in real-time. Non-critical data is processed asynchronously or in batches, reducing energy consumption while maintaining rapid response for safety-critical events.
Solution Approach 2:
The system uses periodic action by processing data at different rates based on priority. Critical fault detection operates continuously in real-time, while non-critical monitoring functions use periodic sampling and batch processing, optimizing the balance between response speed and energy consumption across different system functions.
