Vehicle Repeater Pattern for Wireless Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices associated with a vehicle, located outside the vehicle, face limitations in receiving wireless power, as existing systems are limited to charging batteries and are not capable of directly driving devices, and are restricted to low-power transmission, primarily through RF energy, which is not suitable for fast charging or powering various electronic devices outside the vehicle, especially when the vehicle is turned off.
Innovation Solution
A wireless power supply device and method that utilizes a repeater with patterns to transmit electric or magnetic fields through vehicle surfaces, enabling power transmission to both internal and external devices, using various energy forms and operating independently of the vehicle's power state, allowing for fast and high-power delivery to multiple electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If RF energy is used for wireless power transmission in vehicles, then power can be transmitted to electronic devices, but the transmission power is limited to low power and fast charging is not achievable
Solution Approach 1:
The patent combines multiple wireless power transmission technologies (RF energy, magnetic resonance, and other energy forms) into a single integrated system. This merging allows the system to overcome the limitations of individual technologies and achieve both high power transmission and fast charging capabilities simultaneously.
Solution Approach 2:
The wireless power transmission system is designed to perform multiple functions: it can transmit low power for battery charging, high power for fast charging, and directly drive electronic devices. This multi-functionality resolves the contradiction by making the system adaptable to different power requirements.
2Power
If wireless power is provided through vehicle power sources, then power can be supplied to devices, but the power cannot be supplied when the vehicle is turned off
Solution Approach 1:
The system is designed to operate in multiple modes: when the vehicle is on, it draws power from vehicle sources; when the vehicle is off, it switches to external power sources or stored energy. This multi-functionality ensures continuous power availability regardless of vehicle operational status.
Solution Approach 2:
The patent introduces external power sources and energy storage components as intermediaries between the vehicle power system and electronic devices. These intermediaries enable power transmission even when the vehicle is turned off, decoupling the power supply from the vehicle's operational state.
3Productivity
If wireless power system is designed for high power transmission, then fast charging is achievable, but the system complexity increases
Solution Approach 1:
The system dynamically adjusts its configuration based on power requirements. For low power applications, it uses simpler RF transmission; for high power fast charging, it activates additional components like magnetic resonance modules. This dynamic adaptation achieves fast charging capability while minimizing system complexity for each operating mode.
