Engineering Contradiction Analysis
1Reliability
If maximum power is supplied regardless of load, then power supply reliability is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the powered device detects the actual power consumption and communicates this information back to the power sourcing equipment. The PSE then adjusts its output accordingly, ensuring reliable power supply while avoiding energy waste by matching output to actual load requirements.
Solution Approach 2:
The system transitions from a static maximum power supply mode to a dynamic adjustment mode. The power output is continuously adjusted based on real-time load detection, allowing the system to maintain reliability while optimizing energy efficiency according to actual power needs.
2Power
If multiple power sourcing equipments are used, then power supply capacity is improved, but system complexity increases
Solution Approach 1:
The patent divides the power supply system into multiple independent power sourcing equipments, each capable of serving specific powered devices. This segmentation allows the system to scale power capacity by adding individual units without requiring complete system redesign, managing complexity through modular architecture.
Solution Approach 2:
Each power sourcing equipment is designed with universal functionality to detect power consumption, communicate with powered devices, and adjust output dynamically. This multi-functionality reduces overall system complexity by using standardized components rather than specialized units for each function.
