Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distributed control systems are made large-scale and complex to achieve high reliability through redundancy, then system reliability improves, but the difficulty of deploying distributed functions and configuring network resources increases
Solution Approach 1:
The patent introduces a network planning apparatus as an intermediary between system requirements and actual network configuration. This apparatus automatically performs deployment planning and resource allocation, mediating between the complex redundancy requirements and the actual configuration of distributed functions, thereby maintaining high reliability while reducing deployment complexity
Solution Approach 2:
The patent performs preliminary deployment planning and resource allocation before actual system deployment. The network planning apparatus pre-configures time slots, bandwidth allocation, and function distribution in a planned manner, avoiding complex on-site configuration work and reducing deployment difficulty while ensuring reliability through predetermined redundancy arrangements
2Measurement precision
If time slot communication is used to improve time determinability in control networks, then communication delay determinability improves, but the complexity of configuring network resources such as time slots increases
Solution Approach 1:
The network planning apparatus serves as an intermediary that automatically manages time slot configuration and network resource allocation. It translates communication requirements into specific time slot assignments and bandwidth allocations, maintaining precise communication delay determinability while eliminating manual configuration complexity
Solution Approach 2:
The patent implements automatic feedback mechanisms where the network planning apparatus continuously monitors network status and communication requirements, then automatically adjusts time slot allocations and resource distribution. This feedback loop maintains precise timing control while adapting to changing conditions without manual intervention, reducing configuration complexity

AI summary
Example implementations described herein generate plans for the deployment of functions involving the distribution function and the allocation of network resources based on the requirements of the distributed functions on the control system and the network information constituting the control system. Example implementations involve gathering requirements of the distributed functions constituting the distributed control system, information of the network, and information of the plurality of communication devices, and generating a plan for deployment of the distributed functions to corresponding ones of the plurality of communications devices and allocation of network resources to the corresponding ones of the plurality of communication devices based on the gathered requirements and the information of the network.
