Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate transceiver modules are mounted for communication between transmitting end and receiving end, then communication function is achieved, but cost and construction complexity increase
Solution Approach 1:
The patent combines the communication transceiver module with the wireless power transmission/reception modules, allowing the same hardware components to perform both power transmission and data communication functions. This merging eliminates the need for separate transceiver modules, thereby reducing construction complexity and cost while maintaining full communication capability.
Solution Approach 2:
The wireless power transmission module and reception module are designed to serve dual purposes: transmitting/receiving power and transmitting/receiving communication signals. By making these modules multi-functional, the system achieves communication capability without requiring additional dedicated transceiver hardware, thus simplifying the overall device construction.
2Loss of energy
If magnetic induction technology is used for wireless power transmission, then power transmission efficiency is high, but alignment dependency and heat generation increase
Solution Approach 1:
The patent employs magnetic resonance technology that operates at specific resonant frequencies determined by the coil inductor L and capacitor C. By tuning the system to resonate at these specific frequencies, power can be transmitted efficiently over longer distances without the severe alignment dependency and heat generation problems associated with traditional magnetic induction. The resonant frequency parameter becomes the key control variable for optimizing power transmission.
3Length of stationary object
If magnetic resonance technology is used to transmit power over several meters, then transmission distance is improved, but high resonance characteristics are required
Solution Approach 1:
The patent incorporates a feedback mechanism where the transmitting end and receiving end communicate to detect and confirm resonant frequency matching. The system transmits test signals, receives feedback about the resonance state, and adjusts the transmission parameters accordingly. This feedback loop ensures that the high resonance characteristics required for long-distance power transmission are reliably maintained and optimized.

AI summary
Disclosed herein is a wireless power transmission/reception apparatus and method having a communication function.The wireless power transmission/reception apparatus includes a wireless power transmission device and wireless power transmission devices. The wireless power transmission device receives a returned wireless power signal, detects the number of power consumption devices, modulates pieces of ID data, each including ID of a corresponding power consumption device, transmits the modulated ID data, receives returned ID data, and determines suitableness of the power consumption devices. Each of the wireless power reception devices returns a remaining wireless power signal which is not received among wireless power signals from the wireless power transmission device, and temporarily stops a power consumption device when an ID of the received ID data is an ID of a power consumption device connected thereto, thus returning ID data which will be subsequently received to the wireless power transmission device.
