Engineering Contradiction Analysis
1Productivity
If conventional inline power management is used, then basic power delivery is achieved, but power allocation efficiency is poor and overcurrent protection is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the inline power controller continuously monitors current consumption of powered devices and dynamically adjusts power allocation. The controller receives current consumption data from powered devices, compares it against allocated power budgets, and modifies power delivery in real-time to optimize allocation efficiency while preventing overcurrent conditions through automatic circuit breaker functionality.
Solution Approach 2:
The patent applies preliminary action by performing power discovery and classification before full power delivery. The controller identifies powered devices, determines their power requirements through classification protocols, and pre-allocates power budgets before enabling full power transmission. This preliminary assessment ensures efficient power distribution and establishes protection parameters in advance.
2Productivity
If detailed power monitoring and control is implemented, then power management efficiency improves, but system complexity increases
Solution Approach 1:
The inline power controller is designed as a multi-functional device that consolidates discovery, classification, power budgeting, real-time monitoring, and overcurrent protection capabilities into a single controller. This universal approach manages multiple powered devices through unified protocols while providing detailed power tracking and control, improving management efficiency without proportionally increasing system complexity through modular functional integration.
Solution Approach 2:
The patent merges discovery, classification, and power management functions into an integrated controller system. Rather than separate systems for device identification, power requirement determination, and power delivery control, the invention combines these functions into a unified controller that handles the complete power management lifecycle, reducing overall system complexity while maintaining detailed monitoring capabilities.
3Use of energy by moving object
If dynamic power allocation is implemented, then power resource utilization improves, but control mechanism complexity increases
Solution Approach 1:
The patent implements dynamic power allocation where the controller continuously monitors current consumption of powered devices and adjusts power delivery in real-time based on actual needs. Power budgets are dynamically reassigned when devices are added or removed from the network, and the controller modifies transmission parameters adaptively. This dynamic approach maximizes power resource utilization while using automated control algorithms to manage complexity rather than increasing mechanical or manual control mechanisms.

AI summary
An inline power controller (204) includes at least one analog interface circuit module (AICM) (218) having a first analog input node fo receiving an inline power port voltage, a second analog input node for receiving an inline power port current, a first analog output for effecting an inline power port voltage, a second analog output for effecting an inline power port current, and a digital interface (222) converting the received inline power port voltage to a digital value, the inline power port current to a digital value, a first digital value to the first analog output and a second digital value to the second analog output. A digital serial bus (DSB) (214) couples the AICM (218) to a digital controller (208) via digital serial bus interfaces (DSBIs) (226).
