Inline Power Adapter for PoE Retrofitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting existing cabling for data communication to provide power to powered devices via Power-Over-Ethernet (POE) is expensive, and network outages disrupt continuous communication services, particularly during the migration to IP Telephony, due to switch failures, network overload, and power supply issues.
Innovation Solution
An adapter configured as Power Sourcing Equipment (PSE) that couples an inline powered communications device to a network via a pair of ports, with a translation module for format transformation between different data formats and a power regulator to supply operating power, enabling the use of existing cabling for both data and power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Power-Over-Ethernet (POE) is implemented to provide power to communications devices, then power delivery capability is improved, but cabling cost increases
Solution Approach 1:
The existing data cabling infrastructure is made multi-functional by enabling it to carry both data signals and power simultaneously. The adapter couples power and data connections through the same cabling, allowing the cable to serve dual purposes: traditional data communication and power delivery to POE devices, thereby eliminating the need for separate power cabling and reducing overall cabling costs
Solution Approach 2:
The patent merges power delivery and data communication functions into a single integrated system. The adapter combines power connections and data connections, allowing both to traverse the same cabling infrastructure. This consolidation eliminates redundant cabling and reduces installation complexity while maintaining both power delivery and data communication capabilities
2Adaptability or versatility
If network switches are upgraded to support POE and IP Telephony, then power delivery and communication capability are improved, but network stability deteriorates due to outages during migration
Solution Approach 1:
The adapter acts as an intermediary device between existing network infrastructure and POE communications devices. It provides POE functionality at the endpoint level rather than requiring upgrades to core network switches. This mediator approach enables POE deployment without disrupting the existing stable network core, allowing gradual migration while maintaining network stability and avoiding outages
Solution Approach 2:
The adapter enables preliminary POE deployment at the device level before full network switch migration is complete. By providing power delivery capability at the endpoint, organizations can begin deploying IP telephony and POE devices incrementally, testing and validating the migration process while maintaining fallback options, thereby reducing migration risk and maintaining network stability throughout the transition
3Ease of manufacture
If existing cabling is used for both data and power transmission, then installation cost is reduced, but device complexity increases due to format transformation requirements
Solution Approach 1:
The adapter extracts and isolates the format transformation function into a dedicated translation module. This separate module handles the complexity of converting between data formats and power protocols, while the rest of the system maintains simple, standard connections. By extracting the complex transformation logic into a self-contained component, the overall system becomes easier to install and maintain despite the inherent complexity of multi-format support
