Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional supply chain management systems are used for tracking temperature-sensitive products, then system complexity is reduced, but measurement precision and reliability of temperature monitoring deteriorate
Solution Approach 1:
The system divides temperature monitoring into discrete blockchain blocks, with each block containing temperature readings at specific time points. This segmentation allows for precise tracking of temperature conditions throughout the supply chain while maintaining manageable system complexity through modular data organization.
Solution Approach 2:
The patent introduces smart contracts as intermediaries between temperature sensors and the blockchain ledger. These smart contracts automatically verify temperature readings against predefined thresholds and record deviations, eliminating the need for complex manual monitoring systems while ensuring measurement precision through automated validation.
2Reliability
If manual temperature recording methods are used, then device complexity is reduced, but loss of information and reliability deteriorate due to potential tampering and errors
Solution Approach 1:
The system pre-configures smart contracts with temperature thresholds and validation rules before deployment. This preliminary setup ensures that all temperature readings are automatically validated and recorded with tamper-proof blockchain timestamps, guaranteeing record integrity without requiring complex real-time intervention systems.
Solution Approach 2:
The blockchain system performs self-validation of temperature records through cryptographic hashing and consensus mechanisms. Each temperature reading is automatically verified and sealed in an immutable block, eliminating the need for external verification personnel or complex audit systems while maintaining high reliability.
3Reliability
If comprehensive temperature monitoring is implemented, then reliability and measurement precision improve, but loss of time and productivity deteriorate due to data management overhead
Solution Approach 1:
The system implements real-time feedback through smart contracts that immediately flag temperature deviations as they occur. This automated feedback mechanism eliminates the need for manual data verification and analysis, as the system self-identifies and records compliance issues instantly, maintaining high reliability without time loss.
Solution Approach 2:
The patent replaces manual data verification processes with automated cryptographic validation. Blockchain's inherent consensus mechanisms and digital signatures automatically verify temperature record authenticity and integrity, eliminating time-consuming manual audits while ensuring comprehensive cold chain compliance.
4Reliability
If decentralized blockchain recording is used, then reliability and tamper-proof capability improve, but device complexity and ease of operation worsen
Solution Approach 1:
The smart label device performs self-registration with the blockchain network and automatically submits temperature readings without user intervention. This self-service capability maintains tamper-proof security through decentralized verification while simplifying operation, as users only need to attach the device without managing complex cryptographic keys or network connections.
