Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PoE device relies solely on primary power source, then the device complexity is reduced, but the reliability of power supply deteriorates during power outages
Solution Approach 1:
The patent combines the primary power source and backup power source into a unified PoE injection device. The backup battery is integrated within the same device housing as the primary power input and PoE output, creating a single consolidated unit that automatically switches between power sources without requiring separate backup systems or manual intervention.
Solution Approach 2:
The backup battery is pre-charged and positioned in a ready state within the PoE injection device before any power outage occurs. The system continuously monitors power availability and automatically activates the backup battery when primary power fails, eliminating the need for manual setup or activation during emergencies.
2Speed
If a standby power source is used, then the device complexity is reduced, but the response time to power failure increases
Solution Approach 1:
The primary power source and backup battery are integrated into a single PoE injection device with unified power management circuitry. This consolidation enables instantaneous switching between power sources through electronic control, eliminating the delays associated with separate standby systems that require manual activation or complex switching mechanisms.
3Loss of information
If PoE devices lack backup power, then the device complexity is reduced, but the loss of data and downtime increases during power outages
Solution Approach 1:
The backup battery is integrated within the PoE injection device to provide continuous power delivery through the Ethernet cable to connected PoE devices. This ensures that security cameras, alarms, and other networked devices maintain uninterrupted power supply, preventing data loss from abrupt shutdowns and avoiding downtime without requiring individual backup power sources at each endpoint device.
