Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless energy transmission techniques are inefficient for large capacity data transmission when combined with power transmission, as they often use low frequencies that are vulnerable to interference and limited to near-field communication.
Innovation Solution
The use of a resonant structure that separates energy transmission frequencies from data transmission frequencies, employing a power transmission frequency and a communication frequency that is an integer multiple of the power transmission frequency, allowing for simultaneous high-efficiency energy and data transfer using a single resonator and radiator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same frequency is used for both wireless power transmission and communication, then the system complexity is reduced, but the data transmission capacity and efficiency deteriorate due to near-field limitations and vulnerability to interference
Solution Approach 1:
The patent segments the frequency spectrum by dividing it into two distinct bands: a first frequency band for power transmission and a second frequency band for communication. This segmentation allows independent optimization of each function, enabling high-capacity data transmission while maintaining efficient power transfer without the limitations of near-field communication.
2Reliability
If a low frequency is used for communication during wireless power transmission, then the system can operate in near-field conditions, but the data transmission speed and capacity are severely limited
Solution Approach 1:
The patent changes the frequency parameter by using a second frequency band that is higher than the first frequency band for communication. This parameter change enables the system to overcome near-field limitations and achieve high-speed, large-capacity data transmission while the power transmission continues at the lower first frequency band.
3Productivity
If separate frequencies are used for power transmission and communication, then large capacity data transmission at high speed is enabled, but the system complexity and device structure increase
Solution Approach 1:
The patent applies multi-functionality by designing a unified wireless transmission system that can simultaneously perform both power transmission and communication functions. The system uses a first frequency band for power transmission and a second frequency band for communication, allowing a single device to handle both functions without requiring completely separate systems.
4Volume of moving object
If the same antenna system is used for both power and data transmission, then the device size is reduced, but the energy transmission efficiency and communication performance cannot be optimized simultaneously
Solution Approach 1:
The patent applies local quality by optimizing different parts of the frequency spectrum for different functions. The first frequency band is optimized for power transmission efficiency, while the second frequency band is optimized for communication performance. This allows each function to operate at its optimal frequency without compromising the other.
