Engineering Contradiction Analysis
1Adaptability or versatility
If devices from different operators are networked in a heterogeneous network, then device diversity and operational flexibility are improved, but control and monitoring of instruction sequences becomes difficult
Solution Approach 1:
The patent implements a universal control framework based on blockchain technology that can handle instruction sequences across diverse devices from different operators. The standardized smart contract execution environment provides a common interface for controlling heterogeneous devices, enabling multi-operator networks to function coherently without requiring operator-specific control mechanisms.
Solution Approach 2:
The blockchain system acts as an intermediary layer between control systems and diverse devices. Smart contracts serve as mediators that standardize instruction sequence execution, translating operator-specific control requirements into universally executable instructions while maintaining security and traceability across the heterogeneous network.
2Productivity
If standardized control mechanisms are implemented across heterogeneous devices, then control efficiency is improved, but system complexity increases
Solution Approach 1:
The blockchain system enables devices to self-verify instruction sequences through cryptographic validation and consensus mechanisms. Devices automatically execute standardized control instructions based on smart contract conditions without requiring complex external coordination, improving control efficiency while the distributed nature of the system prevents complexity concentration at any single point.
3Reliability
If distributed database systems like blockchain are used for control transactions, then security and trust are improved, but transaction costs and processing time increase
Solution Approach 1:
The patent applies partial blockchain validation by using consensus mechanisms only when necessary for security-critical operations, while allowing faster validation for routine control transactions. This selective approach maintains security where needed while reducing processing time for standard operations, balancing reliability requirements with efficiency concerns.
