PoE Injector Backup Power and Wireless Failover for Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power over Ethernet (PoE) devices face disruptions due to loss of primary power and internet connectivity, leading to data loss, downtime, and increased costs, as existing solutions lack immediate and reliable backup systems for both power and internet connectivity.
Innovation Solution
A system and method that provide uninterruptible PoE using a rechargeable power supply with self-controlled power management, network routing, and wireless internet backup, including a power over Ethernet injector device with a rechargeable power source, primary power monitoring, and internet connectivity monitoring, automatically redirecting power and establishing wireless internet connectivity upon primary power or internet failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PoE device relies on primary power source and wired internet connection, then the system operates normally with stable power and connectivity, but the system experiences downtime and data loss when primary power or internet connection fails
Solution Approach 1:
The rechargeable power supply is pre-charged and ready to immediately take over when primary power fails. The system performs preliminary power preparation by maintaining a charged backup source, eliminating the delay associated with activating standby systems during power outages.
Solution Approach 2:
The rechargeable power supply acts as an intermediary between the primary power source and the PoE device. It buffers power transitions, providing continuous power delivery during switches from primary to backup power, thereby preventing downtime and maintaining operational continuity.
2Reliability
If a PoE device relies on primary power source and wired internet connection, then the system operates with stable connectivity, but the system loses internet connectivity and requires manual reconfiguration when primary connection fails
Solution Approach 1:
The system automatically detects failures in the primary internet connection and self-configures to use wireless backup connectivity without human intervention. The PoE device and power supply work together to maintain connectivity, eliminating the need for manual reconfiguration during failures.
Solution Approach 2:
The system continuously monitors the status of the primary internet connection and automatically switches to wireless backup connectivity when failures are detected. This feedback mechanism ensures seamless connectivity maintenance by responding to connection status changes in real-time.
3Reliability
If a standby or emergency system is used as backup power source, then the system provides alternative power when primary fails, but the system experiences delay during activation and switchover
Solution Approach 1:
The rechargeable power supply is maintained in a pre-charged, ready-to-operate state continuously, eliminating the activation delay associated with standby systems. When primary power fails, the pre-prepared backup power immediately takes over, providing instantaneous continuity.
Solution Approach 2:
The system transitions from a static standby configuration to a dynamic rechargeable backup configuration that can actively maintain power delivery. The rechargeable supply dynamically adjusts between charging and discharging modes, enabling immediate response to power failures without switchover delays.
4Device complexity
If PoE devices are used without backup power, then the system has simpler configuration, but the system suffers from data loss, repair costs, and revenue loss during power disruptions
Solution Approach 1:
The rechargeable power supply serves multiple functions: it acts as a backup power source, a power management controller, and a connectivity maintenance device. This multi-functionality addresses various loss scenarios (data loss, downtime, repair costs) through a single integrated solution rather than multiple separate components.
