Engineering Contradiction Analysis
1Length of stationary object
If high impedance cabling is used to transmit digital data and power over long distances, then transmission distance is extended and power loss is reduced, but signal quality degradation and compatibility issues across different protocols occur
Solution Approach 1:
The system segments the transmission medium by using existing electrical wiring infrastructure (power lines) as the transmission medium for digital signals, rather than requiring dedicated signal cables. This segmentation allows the system to leverage already-deployed infrastructure extending over long distances while maintaining signal integrity through digital modulation techniques adapted for power line communication
Solution Approach 2:
The system makes the electrical wiring infrastructure universal by enabling it to serve multiple functions simultaneously: power distribution and digital data transmission. This multi-functionality eliminates the need for separate signaling infrastructure, allowing existing wiring to support both power delivery and high-speed data communication across the same physical medium without requiring protocol-specific cabling
2Adaptability or versatility
If multiple technologies are used for signal distribution, then compatibility and functionality are improved, but system complexity and installation requirements increase
Solution Approach 1:
The system merges power distribution and digital communication functions into a single integrated infrastructure. By combining these previously separate functions into one system using the same physical medium (electrical wiring), the solution reduces overall system complexity while maintaining versatility through a unified platform that handles both power and data
Solution Approach 2:
The system introduces power line communication technology as an intermediary that enables digital signal transmission over electrical wiring. This intermediary layer translates digital signals into forms suitable for power line transmission and back, providing protocol compatibility and functionality without requiring complex multi-technology implementations
3Loss of energy
If conventional high impedance systems are used for power delivery, then power loss is minimized, but digital signal transmission quality and networking flexibility are limited
Solution Approach 1:
The system changes the parameters of power line transmission by using high-frequency digital modulation superimposed on the power frequency signal. This parameter change allows the same electrical wiring to carry both power (at 50/60 Hz) and digital data (at much higher frequencies), maintaining efficient power delivery while enabling flexible digital networking capabilities
Solution Approach 2:
The system maintains continuous useful action by allowing the electrical wiring to simultaneously perform both power distribution and data transmission without interruption. The dual-function operation continues uninterrupted, with power delivery and digital communication occurring concurrently over the same infrastructure, maximizing the utility of the installed base
