Wireless Power Spot Availability Query via Central Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices face challenges in finding available and sufficient wireless charging spots, as existing systems lack efficient methods to acquire operation state information about nearby charging services, leading to potential occupied or insufficient power issues.
Innovation Solution
A method is introduced where mobile devices and wireless power spots communicate with a server to transmit and receive operation state information, including capacity and availability, allowing users to request and obtain details on nearby spots that meet their power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless power base stations are deployed in public areas, then charging service coverage is improved, but the likelihood of spots being occupied or having insufficient power increases
Solution Approach 1:
The patent implements a feedback mechanism where wireless power base stations continuously report their operation state (power capacity, occupancy status) to a server. The server maintains updated information about all spots and provides this feedback to mobile devices through queries, enabling users to make informed decisions about where to charge their devices.
Solution Approach 2:
The patent introduces a server as an intermediary between wireless power base stations and mobile devices. The server collects reports from base stations, processes the information, and responds to device queries, mediating the information flow to enable efficient spot selection without direct communication between devices and base stations.
2Ease of operation
If users search for nearby wireless charging spots without operation state information, then finding any spot is easier, but the quality and sufficiency of power service cannot be guaranteed
Solution Approach 1:
The patent enables preliminary action by allowing mobile devices to query the server for operation state information before physically traveling to wireless power spots. Users can identify spots with sufficient power capacity and availability in advance, ensuring the quality of service before committing to a location.
3Measurement precision
If a centralized server system is implemented to manage spot information, then information accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal server system that handles multiple functions: collecting reports from wireless power base stations, storing operation state information, processing device queries, and providing responsive information. This multi-functional approach consolidates complexity into a single centralized component rather than distributing it across multiple devices.

AI summary
A method for a mobile device in a wireless power system includes transmitting a request to a server of the wireless power system for acquiring operation state information of a first wireless power spot in the wireless power system, wherein the request at least comprises a required power threshold; and receiving a response comprising the operation state information of the first wireless power spot, wherein the operation state information at least comprises a capacity and an availability of the first wireless power spot.
