Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Power over Ethernet (PoE) is used to remotely power external devices, then data communication devices can be powered through Ethernet cables, but additional Ethernet connection cables and coaxial cables are required, increasing installation complexity
Solution Approach 1:
The patent combines power transmission and control signal transmission into a single coaxial cable system. The voltage conversion apparatus converts control voltages (originally used for satellite device control) into supply voltages capable of powering data communication devices, eliminating the need for separate Ethernet power cables and reducing installation complexity while maintaining remote powering capability
Solution Approach 2:
The coaxial cable is made multi-functional by enabling it to simultaneously transmit power (through voltage conversion from control voltage to supply voltage), control signals (DiSEqC), and data signals. This universal approach allows a single cable type to replace multiple cable types, reducing installation complexity
2Reliability
If separate Ethernet and coaxial cable systems are used for power and signal transmission, then reliable power and data transmission can be achieved, but installation time increases due to multiple cable requirements
Solution Approach 1:
The patent merges power transmission and control functions into a single coaxial cable infrastructure. The voltage conversion apparatus enables the coaxial cable to deliver both power (converted from control voltage levels to supply voltage levels) and control signals through the same cable, significantly reducing installation time by eliminating the need to lay separate Ethernet cables for power delivery
3Device complexity
If control voltage is directly used for powering devices, then simple voltage transmission can be achieved, but the voltage levels are insufficient for powering data communication devices requiring higher supply voltages
Solution Approach 1:
The voltage conversion apparatus changes the voltage parameter from control voltage levels (typically 13-18V for satellite devices) to supply voltage levels (typically 48-55V for PoC power over coaxial cable). This parameter transformation enables the coaxial cable system to power data communication devices while maintaining the simplicity of using the existing control voltage infrastructure
4Adaptability or versatility
If existing coaxial cables are utilized for multiple services, then cable infrastructure efficiency is improved, but voltage level conflicts may occur between control devices and powered devices
Solution Approach 1:
The voltage conversion apparatus resolves voltage level conflicts by dynamically converting between control voltage and supply voltage levels. When the system needs to power a device, it converts the control voltage to the appropriate supply voltage level, ensuring voltage compatibility among multiple devices sharing the same coaxial cable infrastructure while maintaining high cable utilization efficiency
