Engineering Contradiction Analysis
1Speed
If copper cables are used for power and data transmission, then power delivery is reliable, but transmission distance is limited to 100m and data rates beyond 10G are difficult to achieve
Solution Approach 1:
The system segments the transmission functions by using optical fiber for data transmission and copper conductors for power delivery, allowing each medium to operate in its optimal performance range without mutual interference
Solution Approach 2:
The patent combines optical fiber and copper conductors into a single hybrid cable assembly, merging the advantages of both media while maintaining their functional independence for data and power transmission respectively
2Speed
If optical fiber is used for data transmission, then bandwidth and transmission distance are significantly improved, but power transmission capability is lost
Solution Approach 1:
The transmission functions are segmented across different media: optical fiber handles high-speed data transmission while integrated copper conductors handle power delivery, allowing each to excel at its designated function
Solution Approach 2:
The hybrid cable assembly serves multiple functions simultaneously - it provides both optical data transmission and electrical power delivery through its integrated structure, making a single cable solution capable of handling both data and power needs
3Loss of energy
If higher voltage is used for power transmission over optical fiber, then power efficiency improves, but fault detection and safety management become more challenging
Solution Approach 1:
The system implements continuous feedback mechanisms through monitoring circuits that track electrical parameters such as voltage, current, and temperature, enabling real-time fault detection and safety management during high-voltage power transmission
