Solution Overview

Problem

Conventional wireless charging pads require devices to remain stationary and are obsolete as new charging standards emerge, limiting portability and convenience in charging multiple devices.

Innovation Solution

A portable device capable of wireless power transfer, equipped with a power storage module and a power transceiver module that includes a coil for both receiving and transmitting power, allowing seamless power transfer between devices and enabling operation without a dedicated charging pad, with a controller module for managing power transfer standards and optimizing power transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wireless charging pads are used, then wireless charging is enabled, but devices must remain stationary and plugged in to a wall outlet

Engineering Contradiction:
Improvewireless charging convenienceVSAvoiddevice mobility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The portable device is equipped with both a power reception module (coil 214) and a power transmission module (coil 214), enabling it to function both as a wireless charging receiver and a wireless charging transmitter. This dual functionality allows the device to charge itself from a charging pad and subsequently charge other devices wirelessly without requiring those devices to be connected to a wall outlet, thereby resolving the contradiction between wireless charging convenience and device mobility.

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

Solution Approach 2:

The patent combines the power reception module and power transmission module into a single portable device. By merging these two previously separate functions (receiving power from a charging pad and transmitting power to other devices) into one device, the system eliminates the need for multiple separate charging devices and enables mobile wireless charging, thus improving both ease of operation and adaptability.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If conventional wireless charging pads are used, then charging is enabled, but the pads become obsolete as new charging standards emerge

Engineering Contradiction:
Improvecharging capabilityVSAvoidcharging standard compatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The controller module 230 dynamically switches between different power transfer standards (e.g., Qi for power reception and AirFuel for power transmission) based on the requirements of connected devices. This dynamic adaptability allows the portable device to remain compatible with emerging charging standards rather than being locked into a single standard, thereby resolving the contradiction between charging capability and standard compatibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by supporting multiple power transfer standards and switching between them. The controller module 230 can adjust the power transfer protocol, frequency, and other parameters to match the requirements of different devices and standards, ensuring long-term adaptability while maintaining charging capability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a portable device with both power reception and transmission modules is used, then device mobility and versatility are improved, but device complexity increases

Engineering Contradiction:
Improvepower transfer functionalityVSAvoidmodule configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the power reception module and power transmission module into a single integrated system within the portable device. By combining these modules and sharing common components (such as the coil 214 for both receiving and transmitting), the design reduces overall system complexity compared to having completely separate charging devices, while still providing enhanced power transfer functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single coil 214 is designed to serve dual purposes: receiving power from a charging pad and transmitting power to other devices. This multi-functional design reduces the number of separate components needed, thereby managing device complexity while maintaining versatile power transfer capabilities.

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