Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging is used to recharge devices, then reliable power delivery is achieved, but device mobility is restricted and cord clutter increases
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless electromagnetic field-based power transmission system. The transmit resonator generates an oscillating electromagnetic field that couples with the receive resonator, eliminating the need for physical wire connections while maintaining reliable power delivery. This substitution of mechanical connection with electromagnetic field coupling directly resolves the contradiction between reliability and mobility.
Solution Approach 2:
The patent introduces resonant electromagnetic fields as an intermediary medium to transfer power between the charging source and the device. The transmit and receive resonators establish a resonant coupling through the electromagnetic field, acting as a mediator that enables wireless power transfer. This intermediary approach maintains power delivery reliability while eliminating the mechanical constraint of wires, thereby improving device mobility.
2Productivity
If multiple devices are charged simultaneously via wired connection, then power delivery is ensured, but cord clutter increases
Solution Approach 1:
The patent replaces multiple physical wire connections with a single wireless electromagnetic field transmission system. The transmit resonator can simultaneously establish resonant coupling with multiple receive resonators through the electromagnetic field, enabling multiple devices to be charged at once without requiring multiple cords. This eliminates cord clutter while maintaining the ability to charge multiple devices simultaneously.
Solution Approach 2:
The wireless power transmission system provides multi-functionality by enabling simultaneous power delivery to multiple devices through a single transmit resonator. The system can dynamically adjust and maintain resonant coupling with multiple receivers, making the charging source universal and adaptable to various device configurations without the spatial constraints imposed by multiple cords.
3Duration of action of moving object
If battery capacity is increased to meet power demands, then device operation duration is extended, but device weight and size increase
Solution Approach 1:
The patent introduces a wireless power transmission system as an intermediary that provides supplemental power during device operation. Instead of relying solely on large onboard batteries, the device can receive additional power wirelessly through resonant coupling with a transmit resonator. This intermediary power source extends operation duration without requiring the device to carry proportionally larger batteries, thereby avoiding increased weight.
Solution Approach 2:
The system enables preliminary wireless charging before device use, allowing the device battery to be topped up in advance without requiring the device to be connected to a wall outlet via wire. The transmit resonator can charge the device battery preliminarily through wireless resonant coupling, extending the effective operation duration while keeping the device lightweight and portable.

AI summary
Example implementations relate to a solar panel system including solar cells and an inverter configured to receive electrical energy generated by solar cells and to convert the electrical energy to an electrical signal having an oscillation frequency. The system also include a transmit resonator coupled to the inverter and configured to resonate at the oscillation frequency. Moreover, the transmit resonator may be coupled via a wireless resonant coupling link to a receive resonator that is also configured to resonate at the oscillation frequency. Further, the system may also include a controller configured to determine for the system a mode of operation from among the following modes: (i) a common mode, (ii) a differential mode, and (iii) an inductive mode. And the controller is then configured to instruct the transmit resonator to provide via the wireless resonant coupling link electrical power according to the determined mode of operation.
