Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coaxial cable is used for both data transmission and power supply, then installation complexity is reduced and existing infrastructure is utilized, but voltage interference and signal quality deteriorate
Solution Approach 1:
The patent segments the voltage signals into different ranges: control voltages (0-30V) for LNB management and supply voltages (48-60V) for powering communication devices. The conversion apparatus separates these functions by converting between control and supply voltages, allowing simultaneous use of coaxial cable for both data and power without interference.
Solution Approach 2:
The invention changes the voltage parameter dynamically based on the required function. The apparatus can convert control voltages to supply voltages and vice versa, enabling the same coaxial cable infrastructure to support both low-voltage control signals and high-voltage power supply without signal degradation or interference.
2Reliability
If separate ethernet cable is used for power supply (PoE), then reliable power delivery is achieved, but installation complexity and cost increase
Solution Approach 1:
The patent merges the power supply function and data transmission function into a single coaxial cable infrastructure. The conversion apparatus enables the coaxial cable to carry both high-voltage supply signals for powering devices and low-voltage control signals for managing LNBs, eliminating the need for separate ethernet cables and reducing installation complexity.
Solution Approach 2:
The invention makes the coaxial cable universal by enabling it to perform multiple functions simultaneously: data transmission, power supply, and device control. The voltage conversion apparatus facilitates this multi-functionality by managing the conversion between control and supply voltages on the same cable, replacing the need for separate PoE infrastructure.
3Adaptability or versatility
If control voltage is used for both LNB management and device powering, then device functionality is maintained, but voltage compatibility issues arise
Solution Approach 1:
The voltage conversion apparatus acts as an intermediary between the coaxial cable infrastructure and the connected devices. It converts control voltages to supply voltages for powering communication devices while maintaining the original control voltage levels for LNB management, ensuring voltage compatibility for both functions without direct conflict.
4Adaptability or versatility
If voltage conversion apparatus is implemented, then remote powering and control are enabled through single cable, but device complexity increases
Solution Approach 1:
The voltage conversion apparatus is configured to automatically convert between control and supply voltages based on the operational requirements. The system self-manages the voltage conversion process without requiring external intervention, enabling remote powering and control through the coaxial cable while minimizing the need for additional control infrastructure.
