Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical connections are used to connect LAN interfaces, then physical stability is ensured, but flexibility and adjustability of transmission paths are reduced
Solution Approach 1:
The patent replaces manual mechanical connection management with an automated detection system. The detection device automatically identifies wiring paths between LAN interfaces and configures transmission paths through software control, eliminating the need for manual mechanical configuration and significantly improving adaptability while reducing operational complexity.
Solution Approach 2:
The detection device performs self-configuration by automatically detecting the wiring paths and assigning transmission paths without external intervention. The system autonomously negotiates and establishes optimal transmission routes, enabling the network device to adapt to different connection scenarios independently.
2Productivity
If simple transmission paths are used between LAN interfaces, then device complexity is reduced, but testing efficiency and communication performance assessment are limited
Solution Approach 1:
The patent segments the transmission path configuration into multiple independent virtual transmission paths that can be independently detected, managed, and tested. The path distribution unit creates separate logical channels for different data flows, enabling comprehensive testing of multiple paths simultaneously and significantly improving testing efficiency.
Solution Approach 2:
The path distribution unit serves multiple functions: detecting wiring paths, assigning virtual transmission paths, managing data flow routing, and enabling comprehensive network testing. This multi-functional component enhances testing capabilities without requiring separate dedicated systems for each function.
3Extent of automation
If manual configuration of transmission paths is used, then ease of operation is maintained, but automation and testing comprehensiveness are reduced
Solution Approach 1:
The detection device automatically detects wiring paths and configures transmission paths without requiring manual intervention. The system performs self-diagnosis and self-configuration, eliminating the need for operators to manually configure complex network paths while maintaining operational simplicity through automated processes.
Solution Approach 2:
The detection device continuously monitors and detects the actual wiring paths, providing feedback to the path distribution unit which then adjusts transmission path assignments accordingly. This closed-loop feedback mechanism ensures optimal path configuration while automating the entire process, maintaining ease of operation through intelligent automation.

AI summary
An interface detection device in electronic communication with a network tester to receive network packets includes a plurality of local area network (LAN) interfaces, a signal control unit and a path distribution unit. The LAN interfaces are in electronic communication with the network tester and are electrically connected in pairs. The signal control unit provides preset test data for the LAN interfaces and controls the LAN interfaces to generate corresponding verification data. The signal control unit compares the verification data with the test data, and controls the path distribution unit to automatically figure out corresponding transmission paths. The LAN interfaces are electronically communicating with each other through the connected LAN interfaces and the transmission paths to transfer the network packets.
