Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power supply systems face challenges in appropriately supplying power to multiple power receiving apparatuses that request different charging modes, such as normal and fast charging, simultaneously.
Innovation Solution
A power supply apparatus that includes a charging mode information receiving unit, a power supply order determination unit, and a power supply unit, which determines the order of power supply based on charging mode information received from each power receiving apparatus and wirelessly supplies power accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power is supplied to multiple power receiving apparatuses simultaneously, then the power supply system can serve more devices, but it becomes difficult to appropriately manage different charging mode requests from each device
Solution Approach 1:
The patent segments the power supply process by determining a specific power supply order for multiple power receiving apparatuses. Instead of simultaneously managing all devices, the system divides them into a sequence (first power receiving apparatus, second power receiving apparatus, etc.) and supplies power in that order. This segmentation simplifies the management of different charging mode requests by handling devices individually in a predetermined sequence rather than attempting to manage all devices simultaneously.
2Speed
If fast charging mode is provided, then charging speed is improved, but power consumption and heat generation increase
Solution Approach 1:
The patent implements dynamic charging mode switching based on the determined power supply order. The control unit switches between normal charging mode and fast charging mode according to which power receiving apparatus is currently being served. This dynamic adjustment allows the system to provide fast charging (higher power consumption) only when necessary and appropriate, rather than continuously operating at high power consumption levels, thus balancing charging speed requirements with overall power consumption management.

AI summary
A power supply apparatus includes a charging mode information receiving unit configured to receive, from each of a plurality of power receiving apparatuses each including a secondary battery, charging mode information indicating whether each of the power receiving apparatuses requests normal charging of the secondary battery or fast charging of the secondary battery, wherein the fast charging charges faster than the normal charging, a power supply order determination unit configured to determine a power supply order of the power receiving apparatuses based on the charging mode information, and a power supply unit configured to wirelessly supply power to the power receiving apparatuses in the order determined by the power supply order determination unit.
