Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional quality tracing methods are used for prefabricated parts, then the system is simple to implement, but the tracing efficiency and data security are insufficient
Solution Approach 1:
The quality tracing system is segmented into multiple independent nodes (manufacturing nodes, construction nodes, supervision nodes, etc.) that each maintain their own quality data. These nodes are distributed across different organizations in the supply chain, allowing parallel data collection and processing without centralization bottlenecks, thereby improving tracing efficiency while maintaining manageable complexity through modular architecture
Solution Approach 2:
A blockchain intermediary layer is introduced between the various quality tracing nodes to enable secure, trustless data exchange. The blockchain acts as a decentralized mediator that records quality data from different nodes without requiring a central authority, improving both tracing efficiency through automated consensus mechanisms and security through cryptographic verification
2Reliability
If centralized quality information storage is used, then the storage system is simple to manage, but the data security and anti-falsification capability are insufficient
Solution Approach 1:
The centralized storage system is segmented into a distributed network of nodes, each holding a copy of the quality data ledger. This segmentation eliminates single points of failure and falsification, as any node can verify data integrity against others, significantly improving data security and anti-falsification capability while the modular node architecture keeps individual system complexities manageable
Solution Approach 2:
Each node in the distributed storage system maintains local quality data with the same security and verification capabilities. Every node independently validates and stores quality information with cryptographic signatures, ensuring that local data quality matches global data quality standards, thereby improving overall data security without requiring complex centralized verification mechanisms
3Adaptability or versatility
If different quality tracing standards are used by different nodes, then each node can use its own standard, but the intercommunication and integration of quality information are insufficient
Solution Approach 1:
The blockchain quality tracing system implements a universal data structure and communication protocol that can accommodate multiple quality standards and formats from different nodes. The system accepts quality data in various formats from manufacturing, construction, and supervision nodes while standardizing the underlying ledger structure, enabling seamless intercommunication and integration of quality information across diverse standards without information loss
