Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If Power over Ethernet (PoE) techniques are used to transmit power and data via a single Ethernet cable, then the number of cables is reduced and installation is simplified, but the data transmission bandwidth and cable length are limited, requiring additional repeaters and boosters for high-bandwidth devices
Solution Approach 1:
The patent segments the single cable into separate optical conduits for data and power transmission. Each conduit is optimized for its specific function, with the data conduit carrying high-bandwidth optical signals and the power conduit delivering electrical power, thereby resolving the bandwidth limitation of conventional PoE systems while maintaining single-cable simplicity
Solution Approach 2:
The patent replaces electrical signal transmission for data with optical signal transmission. By using optical conduits instead of electrical conductors for data, the system achieves significantly higher bandwidth capacity and transmission distance without requiring additional repeaters, while power transmission continues through dedicated electrical conduits
2Quantity of substance
If Ethernet cables are used for high-bandwidth data transmission, then data communication capability is improved, but the cable length is limited to relatively close proximity requiring signal repeaters
Solution Approach 1:
The patent substitutes electrical signal transmission with optical signal transmission in dedicated optical conduits. Optical signals can travel significantly longer distances without degradation compared to electrical signals in Ethernet cables, eliminating the need for signal repeaters while maintaining high bandwidth capacity
3Quantity of substance
If additional Ethernet cables and repeaters are deployed to meet high bandwidth requirements, then data transmission capability is improved, but the cost and system complexity increase
Solution Approach 1:
The patent merges data transmission and power delivery into a single composite cable structure with dedicated optical and electrical conduits. This integration eliminates the need for separate data cables and power cables, reducing the total number of components while providing sufficient bandwidth for high-performance applications
Solution Approach 2:
The patent replaces the need for multiple Ethernet cables and signal repeaters with a single optical data conduit that provides both high bandwidth and extended transmission distance, thereby reducing system component quantity and overall complexity
