Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard-wired connections are used to connect non-wireless sensors to BMS controllers, then reliable data transmission is achieved, but installation and maintenance costs increase significantly
Solution Approach 1:
A wireless communication module serves as an intermediary device that connects wired sensors to the wireless BMS network. The module includes a wireless transceiver, processing circuit, and power supply, receiving data from wired sensors via analog or digital inputs and transmitting it wirelessly to BMS controllers, thereby eliminating the need for direct hard-wired connections from sensors to controllers
Solution Approach 2:
The patent replaces the mechanical hard-wired connection system with a wireless communication system. Instead of running physical wires from sensors to controllers through building infrastructure, the solution uses wireless radio frequency communication to transmit sensor data, eliminating the need for complex wiring installation and maintenance
2Speed
If wireless communication modules operate continuously in standard mode, then data transmission speed is maximized, but energy consumption increases
Solution Approach 1:
The wireless communication module operates in periodic cycles, alternating between low power mode and standard operation mode. The processing circuit transitions to standard operation mode at predetermined intervals to read sensor values and transmit data, then returns to low power mode to conserve energy, achieving a balance between data transmission requirements and energy conservation
Solution Approach 2:
The system dynamically adjusts its operational state based on data transmission needs. The processing circuit can instantly transition from low power mode to standard operation mode when value changes are detected at binary inputs, ensuring timely data transmission while minimizing energy consumption during stable conditions
