Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate wired/wireless communication protocols are implemented between the speed measuring part and controller, then information exchange capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The existing power supply wire is made to serve dual purposes: both delivering electrical power and transmitting communication signals. By implementing power line communication (PLC) on the power wire, the system eliminates the need for separate communication wiring while maintaining full information exchange capability between the controller and speed measuring part.
Solution Approach 2:
The patent combines the power transmission function and communication function into a single wire infrastructure. The power wire that was previously used only for electrical power delivery is now merged with communication signal transmission, reducing the total number of wires and connection points required in the system.
2Loss of information
If separate communication protocols are added, then information exchange capability is improved, but manufacturing cost increases
Solution Approach 1:
The power wire is designed to perform multiple functions simultaneously - power delivery and data communication. This multi-functionality eliminates the need for additional communication protocol hardware and wiring, thereby reducing manufacturing costs while maintaining full information exchange capability.
Solution Approach 2:
The existing power infrastructure is utilized to provide communication services without requiring separate dedicated communication wiring. The system leverages the already-present power wire to carry both power and communication signals, making the communication function self-supported through the existing structure.
3Device complexity
If existing power lines are used for communication, then device complexity and cost are reduced, but communication speed and data transfer capability may be limited
Solution Approach 1:
The patent employs high-frequency carrier wave modulation to encode communication signals on the power line. By changing the frequency parameter of the signal and using advanced modulation techniques, the system achieves high-speed data transfer over the power line infrastructure, overcoming the traditional limitation of slow PLC communication.
