Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are installed to monitor facility conditions in real-time, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The system divides the facility monitoring into multiple sensor units distributed at different locations, each collecting local status information. This segmentation allows comprehensive monitoring without requiring a single complex centralized system, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The blockchain platform serves multiple functions simultaneously: it stores sensor data, performs safety diagnosis, issues electronic certificates, and provides data sharing among stakeholders. This multi-functionality reduces the need for separate systems, improving measurement precision while controlling overall system complexity.
2Reliability
If subjective evaluation by safety diagnosis experts is used, then ease of operation is maintained, but reliability and measurement precision deteriorate
Solution Approach 1:
The system implements automated feedback loops where sensor data is continuously collected, analyzed by diagnosis units, and used to generate safety assessments. This automated feedback mechanism improves reliability by eliminating subjective bias while maintaining ease of operation through systematic processing rules.
Solution Approach 2:
The blockchain system performs self-service by automatically validating sensor data, executing safety diagnosis algorithms, and issuing certificates without requiring manual intervention. This automation enhances reliability while keeping the system easy to operate through predefined protocols.
3Loss of time
If safety diagnosis is performed only at evaluation time, then device complexity is minimized, but loss of time and productivity deteriorate
Solution Approach 1:
The system performs preliminary safety assessments by continuously monitoring facility conditions and comparing them against safety thresholds before actual safety incidents occur. This preliminary action reduces response time by enabling early detection while managing complexity through automated alert systems.
Solution Approach 2:
The monitoring system operates continuously rather than periodically, maintaining constant surveillance of facility conditions. This continuity reduces time loss by ensuring immediate detection of safety issues while managing complexity through efficient data processing and blockchain immutability.
4Reliability
If electronic documents are issued without blockchain verification, then ease of operation improves, but reliability and loss of information worsen
Solution Approach 1:
The blockchain acts as an intermediary layer that automatically verifies and records safety diagnosis data before issuing electronic certificates. This intermediary mechanism ensures document authenticity through cryptographic verification while maintaining ease of operation by automating the verification process without manual intervention.
Solution Approach 2:
The system creates immutable digital copies of safety diagnosis data on the blockchain, ensuring document authenticity through cryptographic hashing. This copying mechanism prevents tampering while keeping the issuance process simple through automated generation of certificate documents from verified data.
