Solution Overview

Problem

Power delivery in Power over Ethernet (PoE) systems is inflexible due to limited Printed Circuit Board (PCB) space, making it difficult to support additional functions and efficiently deliver different types of power.

Innovation Solution

A modular power control block system that includes a power input, pulse power module, PoE module, and power controller, allowing for the selection and delivery of pulse power or PoE to a transmission line connector, which can be coupled with other blocks to avoid bus bars and copper usage on the PCB.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single power circuit is used to deliver power in a PoE system, then PCB space is conserved, but flexibility to support additional functions is reduced

Engineering Contradiction:
ImprovePCB spaceVSAvoidflexibility to support additional functions
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The power control circuit is divided into multiple independent modules, each capable of delivering different types of power (PoE, pulse power, etc.). This segmentation allows the system to support multiple power delivery functions while maintaining a compact design that conserves PCB space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power control circuit is designed as a multi-functional module that can deliver various types of power (Power over Ethernet, pulse power, and other power types) through a single integrated circuit. This universality enables the system to support additional functions without requiring separate dedicated circuits for each power type.

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

2Area of stationary object

If multiple power delivery modules are integrated into a single circuit, then PCB space is optimized, but device complexity increases

Engineering Contradiction:
ImprovePCB spaceVSAvoidcircuit complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The integrated power control circuit is organized into distinct functional modules (PoE power delivery module, pulse power delivery module, and other power type modules). Each module is independently designed and controlled, which manages complexity through modular organization while achieving space optimization through integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power control circuit includes a controller that dynamically selects and activates specific power delivery modules based on the required power type. This dynamic control mechanism allows the circuit to perform multiple functions without requiring all modules to be simultaneously active, thereby managing operational complexity while maintaining integration benefits.

Inventive Principle:
Principle #15Dynamics
