Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging is used to recharge battery, then power delivery reliability is improved, but device mobility and usability deteriorate due to cord clutter and movement restrictions
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless electromagnetic induction charging system. The transmitter generates an oscillating magnetic field that inductively couples with the receiver coil in the device, enabling power transfer without physical wire connection. This substitution eliminates cord clutter while maintaining reliable power delivery through electromagnetic coupling.
Solution Approach 2:
The patent introduces an oscillating magnetic field as an intermediary medium to transfer power between the charging source and the device. The transmitter converts electrical power to an oscillating magnetic field, which then inductively couples to the receiver coil to generate electrical current for charging the battery. This intermediary field enables wireless power transfer while maintaining efficiency.
2Use of energy by moving object
If battery capacity is increased to meet power demands, then energy storage is improved, but device weight and size increase
Solution Approach 1:
The patent enables preliminary wireless charging action by allowing devices to charge while in motion or without wire connection. The oscillating magnetic field is continuously generated to maintain power transfer, enabling the battery to be recharged at any location without requiring the device to be stationary or connected via wire, thus reducing the need for oversized batteries to ensure continuous power availability.
3Ease of operation
If wireless power transfer distance is increased, then device mobility is improved, but power transfer efficiency deteriorates due to weak coupling
Solution Approach 1:
The patent employs dynamic frequency adjustment and adaptive impedance matching to maintain optimal power transfer efficiency across varying distances. The system dynamically adjusts the oscillation frequency and coupling parameters based on the distance between transmitter and receiver, enabling efficient wireless power transfer over extended ranges while preserving device mobility.

AI summary
A system and method for a mobile hybrid transmitter/receiver (TX/RX) node for wireless resonant power delivery is disclosed. A hybrid TX/RX can be configured to travel to remote, wirelessly-powerable receivers and deliver power to them wirelessly. A hybrid TX/RX device can include a transmitter component (TX), a receiver (RX) component, and a power store for storing power for supply to remote receivers. The TX/RX device can be configured in an autonomous unmanned vehicle operational to travel between a fixed source transmitter devices and one or more specified locations that may be host to one or more remote receivers. In the location of the one or more remote receivers, the TX component may function to wirelessly transfer power from the power store to the one or more remote receivers. In the location of the fixed source transmitter device, RX component can be configured to receive power via wireless power transfer, and to use the received power to at least partially replenish the power store.
