Solution Overview

Problem

Users of electronic devices face challenges in monitoring the status of wireless charging operations, particularly when multiple devices are charged simultaneously, as not all devices have dedicated displays for charging information, and users need a way to easily track charge time, completion, and queue status without extensive interaction.

Innovation Solution

An apparatus and method that utilize a mobile terminal to receive and present information about wireless charging operations, including charge time remaining, completion percentage, and charging queue status, through user interaction or proximity triggers, using a processor and memory configured to display or provide audible indications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless charging plate charges multiple devices simultaneously, then charging capacity increases, but monitoring complexity increases

Engineering Contradiction:
Improvecharging capacityVSAvoidmonitoring complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a mobile terminal as an intermediary device that receives charging status information from the wireless charging plate and presents it to the user. This mediator consolidates monitoring of multiple devices into a single interface, reducing the complexity burden on both the charging plate and the user while maintaining the ability to charge multiple devices simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mobile terminal serves multiple functions: it acts as a remote display, a notification system, and a control interface for monitoring charging status across multiple devices. By making the mobile terminal universal in its monitoring capability, the system can handle multiple devices without proportionally increasing complexity at each component level.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If device has dedicated display for charging information, then information visibility improves, but device cost and complexity increase

Engineering Contradiction:
Improveinformation visibilityVSAvoiddevice cost
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts the charging information display function from the charged devices and relocates it to the mobile terminal. This separation allows the charged devices to remain simple without dedicated displays, while the mobile terminal handles the information presentation burden, reducing overall system cost and complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of equipping each device with its own display hardware, the system creates a virtual copy of the charging information on the mobile terminal's display. This digital copying approach provides full information visibility without the physical cost and complexity of multiple dedicated displays.

Inventive Principle:
Principle #26Copying

3Measurement precision

If user interacts extensively with charging system, then charging control accuracy improves, but ease of operation decreases

Engineering Contradiction:
Improvecharging control accuracyVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system implements automatic feedback mechanisms where the mobile terminal receives real-time charging status information from the charging plate and pushes notifications to the user. This automated feedback loop maintains charging control accuracy by continuously monitoring and informing users without requiring manual checking or complex user interactions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The charging monitoring system operates autonomously by automatically collecting charging status data, processing it through the mobile terminal, and presenting information to users. This self-service approach maintains precise charging control while minimizing the need for active user participation, thereby improving ease of operation.

Inventive Principle:
Principle #25Self-service

AI summary

Mechanisms are described for providing information to a user regarding a wireless charging operation via the user's mobile terminal. Information may be received from a device engaged in a wireless charging operation, such as the user device being charged and/or the wireless charging plate via which the user device is charged, in response to a trigger. Information such as a charge time remaining, an a mount of charge completed, or a charging queue status may be presented by the user's mobile terminal, such as via a display of the mobile terminal and/or through an audible indication provided by a speaker of the mobile terminal. The trigger may be any of a number of user interactions with the device engaged in the wireless charging operation.
