Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If general-purpose connectors are used for connecting field wireless management stations to different networks, then ease of installation is improved, but connection accuracy deteriorates leading to wrong network port connections
Solution Approach 1:
The connector is segmented into multiple pin groups, where each pin group corresponds to a specific network type (host network, synchronizing network, backbone network). This segmentation allows installers to easily connect the appropriate pins while preventing incorrect connections between different network types.
Solution Approach 2:
Different pin groups within the connector have different functions assigned to them based on their local quality. Each pin group is designed with specific electrical characteristics and connection properties that are optimized for its designated network type, ensuring both ease of installation and connection accuracy.
2Device complexity
If similar connectors are used for different networks, then device complexity is reduced, but reliability deteriorates due to synchronization problems and misconnections
Solution Approach 1:
The connector is divided into multiple pin groups with distinct functions for different networks. This segmentation maintains a single physical connector form (reducing device complexity) while ensuring reliable network-specific connections through functional differentiation of pin groups.
Solution Approach 2:
A single connector design serves multiple network connection purposes through its pin groups. The connector is universal in form but specialized in function, allowing one connector type to reliably connect to host networks, synchronizing networks, and backbone networks simultaneously through its multi-functional pin groups.
3Ease of operation
If redundant field wireless management stations are connected without pin identification, then ease of operation is improved, but trouble resistance deteriorates due to inability to identify connection issues
Solution Approach 1:
Different pin groups are assigned different colors to visually identify their function and corresponding network type. This color coding maintains ease of operation by making the system intuitive while significantly improving trouble resistance by enabling quick identification of connection issues and proper troubleshooting.

AI summary
Provided is a highly reliable network management system that makes it possible to prevent improper connections when redundantly configured field wireless management stations are set up and allows a backbone network to also be made redundant, improving fault tolerance. This network management system, in which field wireless management stations that incorporate gateway functionality and system-management functionality are connected redundantly, is characterized in that a plurality of the field wireless management stations (11, 12) are connected to each other via a synchronization cable (30) and synchronization connectors (CNa, CNb) provided on said synchronization cable (30).
