Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate optical interface and electrical interface are used, then PoE power supply function can be implemented, but device size increases and miniaturization is hindered
Solution Approach 1:
The patent combines the optical interface and electrical interface into a single integrated photoelectric composite interface. This integration allows both optical signal transmission and electrical power supply to share the same physical interface and cable, eliminating the need for separate interfaces and reducing device size while maintaining full PoE functionality.
Solution Approach 2:
The photoelectric composite interface serves multiple functions simultaneously: it provides optical communication capability, electrical power supply capability, and data transmission capability through a single interface. This multi-functionality eliminates the need for separate dedicated interfaces for each function, enabling device miniaturization.
2Ease of operation
If separate optical interface and electrical interface are used, then PoE power supply function can be implemented, but cabling complexity increases and management becomes difficult
Solution Approach 1:
The patent merges the optical cable and power cable into a single photoelectric composite cable that carries both optical signals and electrical power through one unified connection. This eliminates the need for cross-cabling and separate cable management, significantly simplifying installation and on-site maintenance.
3Ease of operation
If separate optical interface and electrical interface are used, then PoE power supply function can be implemented, but interference risk between optical and power cables increases
Solution Approach 1:
By integrating optical and electrical components into a single photoelectric composite cable and interface, the patent eliminates the physical separation and potential interference between separate optical and power cables. The integrated design ensures that optical and electrical signals share the same protected pathway, reducing electromagnetic interference and improving signal stability.
