Power over Ethernet Computer System Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems require separate sources for power and data, which can be inconvenient and costly, especially in installations where Ethernet cabling is already in place, as they do not leverage the potential of Power over Ethernet (PoE) systems for both power and data delivery.
Innovation Solution
A Power over Ethernet (PoE) computer system that integrates a processing unit, memory, and network adapter, allowing for both data and power to be received through a single Ethernet connection, with optional battery backup and power management to ensure adequate power delivery to components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional separate power and data sources are used, then power and data can be delivered reliably, but installation cost and complexity increase
Solution Approach 1:
The patent combines power delivery and data transmission into a single Ethernet cable connection. The network adapter integrates both power reception and data communication functions, eliminating the need for separate power cables and outlets. This merging reduces installation complexity while maintaining reliable power and data delivery through the unified PoE infrastructure.
Solution Approach 2:
The Ethernet cable and network adapter serve multiple functions simultaneously: they transmit data, deliver power, and provide network connectivity. This multi-functionality eliminates the need for separate dedicated power wiring and outlets, reducing installation complexity while ensuring reliable operation through the same infrastructure used for data communication.
2Ease of manufacture
If PoE systems are implemented, then installation cost and time are reduced, but power delivery capability must be sufficient for modern computing requirements
Solution Approach 1:
The patent utilizes Power over Ethernet with Power Injection (POE+PI) technology to deliver up to 71 watts of power through the Ethernet cable. This represents a significant increase from traditional PoE power levels, enabling modern computing requirements while maintaining the installation simplicity of PoE. The power delivery capability is enhanced through parameter changes in the PoE+PI specification.
Solution Approach 2:
The network adapter acts as an intermediary that receives power and data from the Ethernet cable and distributes them to the appropriate components. It manages power allocation to ensure sufficient power delivery to the processing unit, memory, and other components while maintaining the simplicity of the PoE installation approach.
3Ease of operation
If PoE computer systems are designed, then cost and configuration ease improve, but power management complexity increases
Solution Approach 1:
The system automatically manages power distribution through the network adapter and motherboard without requiring manual configuration. The PoE+PI infrastructure provides self-service power delivery where the system autonomously allocates and manages power to components based on their requirements, eliminating the need for complex manual power management while maintaining configuration simplicity.
