Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is sent to cloud for analytics, then analytics capabilities are provided, but bandwidth utilization increases and real-time processing is delayed
Solution Approach 1:
The system segments analytics processing into two parts: lightweight rule-based filtering performed at the edge node for immediate real-time detection, and comprehensive cloud-based analytics for deeper insights. This segmentation enables real-time local processing while maintaining cloud analytics capabilities, resolving the latency issue without sacrificing analytical depth.
Solution Approach 2:
The edge node performs preliminary data filtering and preliminary analytics using pre-loaded rules before data reaches the cloud. This preliminary action at the edge reduces the volume of data needing cloud processing and enables immediate local responses to critical events, eliminating the latency penalty of cloud-only processing.
2Adaptability or versatility
If edge nodes are fixed, then system simplicity is maintained, but adaptability to changing input data patterns is lost
Solution Approach 1:
The edge node software is designed to be dynamic rather than fixed, automatically adapting to changing input data patterns through machine learning models that continuously learn from new data. This dynamic adaptation allows the system to respond to evolving operational conditions without manual intervention, resolving the adaptability limitation of fixed systems.
Solution Approach 2:
The edge node performs self-learning and self-adjustment using machine learning algorithms that automatically adapt to changing data patterns without requiring manual software changes. This self-service capability enables continuous adaptation to new operational conditions while avoiding the complexity of manual software maintenance and updates.
3Productivity
If manual software changes are made for data pattern changes, then system functionality is updated, but maintenance costs and downtime increase
Solution Approach 1:
The machine learning models automatically perform self-learning and self-adjustment to adapt to changing data patterns without requiring manual software changes. This self-service capability eliminates maintenance downtime and reduces operational disruption, allowing the system to continuously optimize its own performance in response to changing conditions.
Solution Approach 2:
The system implements continuous feedback loops where performance data is fed back into machine learning models to automatically refine and optimize data processing patterns. This feedback mechanism enables continuous improvement of system efficiency without manual intervention, resolving the productivity-maintenance time contradiction.
4Loss of information
If comprehensive data is collected and sent to cloud, then analytics depth is improved, but bandwidth consumption increases
Solution Approach 1:
The edge node extracts and processes only the most critical information and anomalies locally using rule-based filtering and machine learning, sending only essential data to the cloud for further analysis. This extraction approach reduces data transmission volume while preserving the most valuable information, resolving the contradiction between data completeness and transmission efficiency.
Solution Approach 2:
The system segments data processing into local edge-based filtering and cloud-based comprehensive analytics. The edge node handles immediate real-time processing and critical anomaly detection locally, while the cloud handles deeper analytical processing. This segmentation reduces the amount of data needing transmission while maintaining comprehensive analytical capabilities.

AI summary
Disclosed are methods, systems, and one or more computer-readable mediums for receiving, at an edge device from an external server, a rules database comprising a set of rules; receiving, by the edge device, first data from at least one device; processing, by the edge device, the received first data by comparing the received data to each rule among the set of rules; identifying a first triggering event in response to detecting a match between the received data and a rule of the rules database; and outputting an alert corresponding to the first triggering event.
