Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate power lines and data lines are used, then electrical energy distribution and data transmission can be provided independently, but installation complexity increases and space requirements multiply
Solution Approach 1:
The patent combines separate power lines and data lines into a single integrated cable structure. The cable includes both electrical conductors for power distribution and optical conductors for data transmission, unified under a common sheathing system. This merging reduces installation complexity and space requirements while maintaining independent functionality of both energy and data pathways.
Solution Approach 2:
The cable is designed as a universal conduit that performs multiple functions simultaneously: it distributes electrical energy through embedded power lines and transmits data through embedded optical conductors. This multi-functional design eliminates the need for separate cable installations for power and data, streamlining the overall system architecture.
2Reliability
If standard circular cable cross-section is used, then manufacturing is simple, but polarity reversal and line interchange cannot be prevented
Solution Approach 1:
The patent employs an asymmetric cross-sectional shape for the cable, specifically a triangular configuration. This asymmetry provides inherent orientation markers that prevent polarity reversal and line interchange during installation. The triangular shape allows installers to correctly identify and connect phases, eliminating the ambiguity present in circular cross-sections while remaining manufacturable through standard extrusion processes.
3Speed
If only electrical lines are used for data transmission, then electrical energy distribution is provided, but data transfer rates are insufficient for future needs
Solution Approach 1:
The patent introduces optical conductors as an intermediary medium for data transmission within the cable system. These optical fibers serve as a high-speed communication channel that coexists with the electrical power lines. The optical conductors enable future-proof data transfer rates while the electrical lines continue to provide power distribution, creating a hybrid system that addresses both current and future requirements.
