Access Device Power Supply via User Terminal Service State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face challenges in powering access devices efficiently, particularly in scenarios where multiple user terminals are connected, as they cannot adapt power supply based on the current service state of each terminal, leading to inequality in power distribution.
Innovation Solution
A method and device that detect connected user terminals and determine which ones to power the access device based on their service state, using idle terminals for power supply, employing a backup battery when all terminals are idle, and managing power distribution through simultaneous, sequential, or selective terminal power allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If reverse power supply from user terminals is implemented, then deployment cost is reduced, but power supply equality among user terminals deteriorates
Solution Approach 1:
The system dynamically adjusts power supply status based on real-time service states of user terminals. The access device receives service state information from each user terminal and dynamically determines which terminals should supply power, changing the power supply configuration from static to adaptive to ensure both cost efficiency and fairness.
Solution Approach 2:
The system changes the power supply parameter (which user terminals supply power) based on service state parameters. When service states change, the system recalculates and adjusts the power supply configuration to maintain equality among terminals while keeping deployment costs low.
2Reliability
If all user terminals are required to supply power, then power supply reliability is improved, but user experience deteriorates due to lack of transparency
Solution Approach 1:
The access device provides feedback to user terminals regarding their power supply status and service states. This transparency allows users to understand why their terminal is or is not supplying power, improving user experience while maintaining reliable power supply through appropriate terminal selection.
3Reliability
If power supply is based on service state, then power distribution fairness is improved, but system complexity increases
Solution Approach 1:
The system segments the power supply decision process into distinct components: service state detection, fairness calculation, and power supply determination. Each user terminal's service state is evaluated independently, and the access device synthesizes this information to make fair power supply decisions, managing complexity through modular processing.
