Solution Overview

Problem

Conventional Power over Ethernet (PoE) systems are limited in range and power capacity, requiring local power sources for high-power devices, and lack integrated thermal management, leading to complex and costly cooling solutions, especially in remote or extreme environments.

Innovation Solution

A PoE+F+C system that delivers high-power energy, fiber-optic data, and cooling within a single cable using optical fibers, electrical wires, and coolant tubes, with an interface module that includes sensors and control systems for monitoring and managing power, data, and cooling, enabling efficient power delivery and thermal management over long distances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If power delivery capacity is increased in PoE systems, then more power can be delivered to remote devices, but cooling requirements increase and cable loss becomes more significant

Engineering Contradiction:
Improvepower delivery capacityVSAvoidcable loss
Core Design Contradiction:
PowerVSLoss of energy

Solution Approach 1:

The patent combines power delivery, data transmission, and cooling delivery into a single integrated cable system. The cable includes power conductors for electrical power transmission, optical fibers for data communication, and coolant channels for thermal management. This merging allows high-power delivery to remote devices while simultaneously providing cooling to offset the increased cable loss and thermal generation, resolving the contradiction between higher power capacity and energy loss.

Inventive Principle:
Principle #5Merging (Combining)

2Length of stationary object

If power is supplied through a local power source for greater distance, then range is extended, but device complexity and installation cost increase

Engineering Contradiction:
ImproverangeVSAvoidsystem complexity
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The patent creates a universal cable system that simultaneously performs multiple functions: delivering electrical power over extended distances, transmitting data via optical fibers, and providing cooling through integrated coolant channels. This multi-functional cable eliminates the need for separate local power sources, data connections, and cooling systems at remote locations, thereby extending range while reducing overall system complexity and installation cost.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If conventional PoE systems are used, then installation is simple, but thermal management is inadequate for high-power devices

Engineering Contradiction:
Improveinstallation simplicityVSAvoidthermal management
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The patent merges conventional PoE simplicity with advanced thermal management by integrating coolant channels directly into the cable structure. The cable maintains the easy installation characteristics of conventional PoE while adding cooling capability through embedded fluid passages that deliver coolant from a central cooling source to remote high-power devices, thereby resolving the contradiction between installation simplicity and thermal management adequacy.

Inventive Principle:
Principle #5Merging (Combining)
