Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Power over Ethernet (PoE) systems are used to supply power and data through a single cable, then device installation is simplified and power consumption is reduced, but the systems lack uninterrupted power supply capability during power outages
Solution Approach 1:
The patent combines a UPS power supply unit with a PoE injection device into a single integrated system. The UPS component provides backup power capability while the PoE injection function delivers power and data through Ethernet cables. This merging allows the system to maintain both installation simplicity of PoE and reliability of UPS during power outages.
Solution Approach 2:
The integrated device performs multiple functions: it acts as both a PoE power injector and a UPS backup power supply. The system can provide powered devices with both primary power through Ethernet cables and backup power from internal battery, while also providing data networking functions. This multi-functionality resolves the contradiction by making a single device capable of both simplified installation and uninterrupted power supply.
2Reliability
If traditional UPS systems are used to provide backup power, then power supply continuity is maintained, but the systems require separate power sources and complex installation infrastructure
Solution Approach 1:
The patent merges the UPS power supply functionality with the PoE injection device into a single integrated unit. Instead of requiring separate UPS systems and PoE injectors, the combination allows backup power capability to be built into the PoE infrastructure itself, reducing overall system complexity while maintaining power supply continuity.
Solution Approach 2:
The integrated PoE-UPS device provides multiple functions in one unit: PoE power injection, UPS backup power supply, and network switching. This multi-functionality eliminates the need for separate dedicated UPS infrastructure, thereby reducing device complexity while maintaining reliability of power supply during outages.
3Speed
If wired internet connectivity is used for PoE devices, then network connection is stable and fast, but the connection is disrupted during power outages
Solution Approach 1:
The system performs preliminary actions by detecting power outage conditions and automatically switching from wired to wireless network connectivity before the disruption fully impacts operations. The integrated device monitors power status and pre-activates wireless backup connections to maintain network stability and speed during transitions.
Solution Approach 2:
The patent introduces wireless network connectivity as an intermediary backup solution. When wired network connection is disrupted due to power outage, the system automatically switches to wireless connectivity through the integrated PoE-UPS device, maintaining network access without significant speed or reliability loss.
4Reliability
If wireless backup connectivity is implemented, then network connectivity continuity is maintained during power outages, but additional devices and infrastructure are required
Solution Approach 1:
The patent combines wireless network interface and backup connectivity functions directly into the PoE-UPS injection device. This integration eliminates the need for separate wireless gateways or additional network infrastructure, as the same device that provides PoE power injection and UPS backup also handles wireless network connectivity, thereby maintaining reliability without increasing overall system complexity.
