Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical data collection systems are used, then data collection is simple, but data safety, accuracy, reliability and traceability cannot be ensured
Solution Approach 1:
The patent introduces an intermediary verification mechanism between the edge device and data processing system. This intermediary layer validates data integrity, origin, and authenticity before data enters the processing system, ensuring reliability without requiring complete system redesign. The intermediary acts as a trusted bridge that enforces security protocols while maintaining data flow efficiency.
Solution Approach 2:
The system performs preliminary verification actions at the edge device before data transmission. By pre-validating data characteristics, generating digital signatures, and establishing traceability markers in advance, the system ensures data reliability is established before it enters the processing pipeline, avoiding the need for complex real-time verification throughout the entire data journey.
2Measurement precision
If no verification mechanisms are implemented, then system operation is simple, but data accuracy and traceability are lost
Solution Approach 1:
The edge device performs self-verification of its own data characteristics and generates its own digital signatures autonomously. This self-service approach ensures data accuracy is maintained at the source without requiring continuous external monitoring or complex operational interventions. The device independently validates its data integrity and provides traceability information without adding operational complexity to the overall system.
3Reliability
If blockchain technology is integrated, then data traceability and security are improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential blockchain verification function from the main data processing system and implements it as a separate, modular component at the edge device. By taking out the traceability verification mechanism as an independent module, the system achieves blockchain-level traceability without requiring full integration of complex blockchain infrastructure throughout the entire system. Only the essential verification functions are extracted and implemented where needed.
