Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If power line communication is implemented by connecting communication apparatuses to the power line infrastructure, then data communication capability is achieved, but portability is impaired
Solution Approach 1:
The patent uses the power line as an intermediary medium that serves dual purposes: traditional power delivery and data communication. By modulating data signals onto the power line carrier, the system enables communication without requiring separate communication infrastructure, thus maintaining portability while achieving data transmission capability.
Solution Approach 2:
The power line infrastructure is made multi-functional by enabling it to simultaneously perform both power delivery and data communication functions. This eliminates the need for dedicated communication infrastructure, allowing the communication apparatus to operate portably while maintaining full communication capability through the existing power line network.
2Reliability
If communication apparatuses are connected to fixed power line infrastructure, then stable power supply and communication are achieved, but system flexibility and portability are reduced
Solution Approach 1:
The system transitions from static infrastructure-dependent operation to dynamic portable operation. The communication apparatus can be moved freely while maintaining power and communication functions by connecting to different power lines, making the system adaptable to various locations without requiring fixed installation.
Solution Approach 2:
By enabling the power line to serve both as power delivery medium and communication channel, the system achieves versatility. The same infrastructure supports both stable power supply and flexible data communication, allowing the apparatus to operate in diverse environments without requiring location-specific infrastructure.
3Reliability
If separate communication infrastructure is deployed for data transmission, then communication reliability is improved, but device complexity and infrastructure maintenance requirements increase
Solution Approach 1:
The patent merges the power delivery function and data communication function into a single integrated system using the power line as a common medium. This consolidation eliminates the need for separate communication infrastructure such as wires, antennas, or base stations, reducing overall system complexity while maintaining communication reliability through the established power line network.
