Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If computers and processors are used to control equipment and systems, then system functionality and control precision are improved, but vulnerability to hacking and unauthorized access increases
Solution Approach 1:
The patent introduces a cyber security system as an intermediary layer between control systems and external networks. This intermediary monitors operational aspects, detects anomalies indicating potential attacks, and prevents unauthorized access while allowing legitimate control operations to proceed, thus maintaining control precision while reducing vulnerability to hacking.
2Reliability
If security monitoring and detection systems are implemented, then system security is improved, but system complexity increases
Solution Approach 1:
The patent implements control devices that perform multiple functions: they serve as both control elements for equipment operation and as security monitoring devices. By making control devices universal and multi-functional, the system achieves enhanced security without adding separate dedicated security hardware, thus limiting the increase in overall system complexity.
3Reliability
If real-time detection and correction of security threats is implemented, then system resilience is improved, but processing requirements and system complexity increase
Solution Approach 1:
The patent implements a self-service security system where control devices autonomously monitor their own operational aspects and automatically detect security threats without requiring external security devices. The system performs self-diagnosis and self-protection, eliminating the need for separate security hardware and reducing overall system complexity while maintaining real-time threat detection and correction capabilities.
4Reliability
If hierarchical security architecture with multiple devices is implemented, then security coverage is improved, but device complexity and communication overhead increase
Solution Approach 1:
The patent merges the functions of control devices and security monitoring devices into a single integrated system. By combining these previously separate functions, the hierarchical security architecture achieves comprehensive security coverage without the communication overhead and complexity of multiple separate devices, as the control devices themselves perform security monitoring functions.
