Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking of data packets is performed, then communication errors can be detected, but the analysis process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces the manual mechanical checking process with an automated analysis device that uses a processor to execute Petri net models. The processor automatically compares actual communication sequences against the Petri net model to detect errors, eliminating the need for manual inspection while maintaining detection accuracy.
Solution Approach 2:
The analysis device performs self-service by automatically analyzing communication sequences without human intervention. The system loads the Petri net model, captures communication data, executes the analysis algorithm, and generates error reports autonomously, making the error detection process independent of manual labor.
2Measurement precision
If data packets are recorded over a long period to search for sporadic errors, then error detection capability improves, but data storage volume and costs increase
Solution Approach 1:
The patent applies preliminary action by pre-compiling the Petri net model from the desired communication sequence before actual analysis begins. This pre-processing step creates a ready-to-use reference model that enables efficient real-time comparison without requiring long-term data accumulation, thus reducing storage needs while maintaining detection capability.
Solution Approach 2:
The system replaces the mechanical approach of storing large volumes of historical data with an algorithmic approach using Petri net modeling. The processor efficiently analyzes communication sequences on-the-fly by comparing against the pre-compiled model, eliminating the need for extensive data archiving while maintaining the ability to detect rare errors.
3Productivity
If automatic analysis using Petri net is implemented, then processing speed and efficiency improve, but device complexity increases
Solution Approach 1:
The patent introduces the Petri net model as an intermediary between the communication sequence and the analysis process. The model acts as a mediator that translates complex communication protocols into a standardized graphical representation, simplifying the comparison process while enabling automated high-speed analysis through systematic state transition evaluation.
