Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual binding of electronic labels to routers is performed, then communication configuration can be set, but IT personnel burden increases and service efficiency decreases
Solution Approach 1:
The electronic label automatically performs network scanning, router selection, and configuration binding without requiring IT personnel intervention. The label independently completes the communication configuration process by scanning available routers, selecting the optimal one based on signal strength, and automatically binding to it, thereby eliminating manual configuration operations.
Solution Approach 2:
The system continuously monitors communication quality parameters such as signal strength and transmission stability. Based on this feedback, the electronic label dynamically adjusts its connection decisions and can switch between routers to maintain optimal communication performance, ensuring reliable service without manual intervention.
2Ease of operation
If frequency scanning method is used to automatically search for router, then operation cost reduces, but battery power is exhausted quickly
Solution Approach 1:
Instead of continuous frequency scanning, the electronic label performs periodic scanning at predetermined intervals. The label scans for available routers at scheduled times, maintains connection information from previous scans, and only initiates new scanning operations when necessary, such as when currently connected routers become unavailable. This periodic approach significantly reduces energy consumption compared to continuous scanning.
Solution Approach 2:
The system pre-configures scanning parameters, frequency bands, and selection criteria before the electronic label needs to connect to a router. This preliminary setup eliminates the need for complex real-time analysis and reduces the computational and energy resources required during actual connection operations.
3Area of stationary object
If routers with overlapping coverage areas are configured, then dead zones are eliminated, but signal interference occurs
Solution Approach 1:
The electronic label dynamically selects and switches between multiple routers based on real-time signal strength and communication quality measurements. When a label is in an overlapping coverage area, it can flexibly connect to the router with the strongest signal or switch between routers as conditions change, maintaining optimal communication without being constrained by fixed router assignments.
Solution Approach 2:
The system introduces communication quality parameters as an intermediary factor in router selection decisions. Instead of relying solely on signal strength or fixed configuration, the label considers multiple quality metrics including signal stability, transmission speed, and interference levels, making informed decisions about which router to connect to in overlapping areas.
