Wireless Power Receiver Client Load Balancing in Multi-Charger Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-wireless power transmission system environments, existing technologies face challenges in efficiently establishing optimal wireless power connections, leading to unbalanced utilization of charging systems, where some systems are underutilized while others serve a maximum number of devices.
Innovation Solution
The method involves a wireless power receiver client that listens for connection invitations from multiple wireless power transmission systems, identifies attributes such as signal strength and number of associated clients, applies selection criteria to determine the optimal system for connection, and scores systems to prioritize power delivery, ensuring efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless device connects to any available charger in a multi-charger environment, then power delivery is established, but the distribution of power delivery load becomes unbalanced with some chargers underutilized and others at maximum capacity
Solution Approach 1:
The wireless device actively queries multiple chargers for their attributes (signal strength, number of associated clients, availability) and uses this feedback information to make an informed connection decision. The device receives connection invitations from multiple chargers, evaluates their current load and capabilities, and selects the optimal charger based on the evaluation criteria, thereby balancing the load distribution across the charger network.
Solution Approach 2:
The system changes the parameter of charger selection from random or first-available to optimized selection based on multiple parameters including signal strength, number of associated clients, and charger availability. By evaluating and comparing these parameters across multiple chargers, the system achieves balanced utilization while maintaining efficient power delivery.
2Productivity
If the wireless device evaluates multiple chargers before connection, then optimal power delivery is achieved, but the connection establishment time increases
Solution Approach 1:
The wireless device performs preliminary evaluation of multiple chargers by listening for and processing connection invitations before actually establishing a power connection. The device gathers attributes such as signal strength and charger load status in advance, ranks the chargers based on evaluation criteria, and only then proceeds to connect to the optimal charger. This preliminary action ensures optimal power delivery while the evaluation process is designed to be efficient.
3Adaptability or versatility
If the wireless device selects the charger with the most available capacity, then load balance is improved, but power delivery speed may be reduced
Solution Approach 1:
The system changes the selection criterion from solely based on charger capacity to a multi-parameter evaluation that includes signal strength, number of associated clients, and charger availability. This multi-parameter approach ensures that the selected charger provides both good signal quality (for fast power delivery) and adequate capacity (for load balance), resolving the contradiction between speed and balance.
