Multi-Port PoE AC Outlet for Higher-Power Device Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PoE systems are limited to delivering approximately 90 watts, which is insufficient for powering devices requiring higher power, such as dishwashers, washing machines, and refrigerators, and do not meet electrical code requirements for AC outlets in residential and commercial environments.
Innovation Solution
A higher power PoE system that combines power from multiple ports at power sourcing equipment, converts DC power to AC power, and manages real-time power distribution through communications cabling to create AC outlets capable of delivering at least 100 watts, with power management to ensure compliance with electrical codes and efficient use of outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional PoE systems are used, then device compatibility and ease of operation are maintained, but power delivery capacity is limited to approximately 90 watts
Solution Approach 1:
The patent combines multiple PoE ports (e.g., four 300W ports) to create a single AC power outlet capable of delivering higher total power (e.g., 1200W). This merging approach allows the system to exceed the 90-watt limitation of conventional PoE while maintaining compatibility with existing PoE infrastructure and devices.
Solution Approach 2:
The system provides multi-functionality by offering both individual PoE power delivery to multiple devices and combined AC power output. The power sourcing equipment can operate in different modes: individual port power delivery for PoE-compatible devices or combined AC output for high-power appliances, thus serving multiple purposes without requiring separate systems.
2Reliability
If conventional PoE systems are used, then system simplicity is maintained, but electrical code requirements for AC outlets cannot be met
Solution Approach 1:
Multiple PoE ports are merged to create AC power outlets that meet electrical code requirements. By combining the power capacity of multiple ports, the system achieves the power levels required for code-compliant AC outlets while still using PoE infrastructure.
Solution Approach 2:
The patent introduces an intermediary conversion process where DC power from multiple PoE ports is converted to AC power. This intermediary step allows the system to bridge between PoE technology and AC power requirements, enabling compliance with electrical codes that mandate AC outlets for certain applications.
3Power
If higher power PoE ports (at least 100 watts each) are implemented, then power delivery capacity is increased, but infrastructure requirements and installation complexity increase
Solution Approach 1:
The system combines multiple high-power PoE ports to create AC outlets, which allows existing PoE infrastructure to be utilized for high-power applications. This approach avoids the need for completely separate high-voltage wiring infrastructure, making installation more straightforward than traditional AC electrical systems.
Solution Approach 2:
The system provides dynamic power allocation where the power from multiple PoE ports can be flexibly distributed - either individually to multiple PoE devices or combined to create AC outlets. This dynamic capability allows the infrastructure to adapt to different power requirements without requiring fixed, complex wiring configurations.
