Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a network system uses multiple gateway devices for device connections, then device flexibility and connectivity options are improved, but the ability to communicate between devices connected to different gateway devices deteriorates (no communication mechanism exists)
Solution Approach 1:
The patent merges multiple gateway devices into a unified logical network structure where gateways can communicate with each other. By creating inter-gateway communication channels and establishing a logical network that spans multiple physical gateways, the system enables devices connected to different gateways to communicate seamlessly, thus resolving the communication barrier while maintaining device flexibility.
Solution Approach 2:
The patent introduces intermediary mechanisms including gateway-to-gateway communication protocols and logical network constructs that act as mediators between devices on different gateways. These intermediaries facilitate message routing and data transmission across gateway boundaries, enabling communication without requiring direct device-to-device connectivity.
2Reliability
If a network system establishes communication between devices on different gateway devices, then communication capability is improved, but system complexity increases (requiring route definition lists and device connection lists)
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically generates and maintains route definition lists and device connection lists. The gateways and controller work together to dynamically discover devices, automatically populate routing information, and update connection records without requiring manual configuration. This automation reduces the perceived complexity for users while maintaining robust communication capabilities.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing the logical network framework and inter-gateway communication channels before devices need to communicate. Route definition lists and device connection lists are prepared and maintained in advance, allowing the system to quickly establish communication paths when devices connect, rather than configuring everything from scratch at the moment of need.
3Measurement precision
If manual configuration of network routes and device connections is required, then communication precision is improved, but ease of operation deteriorates (requires significant user setup)
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors device connections, communication status, and route effectiveness. Based on this feedback, the controller automatically adjusts route definitions and connection lists to maintain precise communication paths. This closed-loop approach ensures communication precision is maintained automatically without requiring users to manually configure or adjust settings.
Solution Approach 2:
The system performs self-service by automatically discovering devices, determining optimal communication routes, and configuring connection lists without user intervention. The automatic configuration processes maintain communication precision through algorithmic route selection and dynamic list updates, eliminating the need for users to perform complex manual setup while preserving accurate device-to-device communication paths.

AI summary
An object is to provide a logical network construction system.A logical network construction system is provided with first and second gateway devices and a controller which communicate with each other via a network, a source device, a destination device, and a storage unit in which an entire device connection list and an entire route definition list are stored. A controller constructs a logical network for communication between a source device connected to a first port of a first gateway device and a destination device connected to a second port of a second gateway device on the basis of an entire device connection list and an entire route definition list.
