Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If directional antennas and RF energy harvesting are used for wireless charging, then wireless power transmission can be achieved, but the device requires precise placement and orientation for a period of time to be charged
Solution Approach 1:
The patent performs capability analysis and authentication before initiating power transfer. The receiver device analyzes transmitter characteristic data and determines compatibility, while the transmitter authenticates the receiver using blockchain-stored credentials. This preliminary verification ensures that power transfer begins only when conditions are optimal, preventing wasted charging time due to incompatibility or unauthorized devices.
Solution Approach 2:
The system implements real-time monitoring and feedback mechanisms where the receiver device continuously analyzes transmitter data and the transmitter monitors receiver authentication status. This feedback loop allows the system to adjust or terminate power transfer based on real-time conditions, ensuring efficient charging without prolonged idle time from improper placement or incompatible devices.
2Adaptability or versatility
If RF energy harvesting with directional antennas is used, then wireless power transmission can be achieved, but the device must be placed in a certain location and orientation for a period of time to be charged
Solution Approach 1:
The patent employs a universal authentication mechanism using blockchain technology that works across different device types and manufacturers. The capability analysis protocol is designed to be device-agnostic, allowing the system to accommodate various receiver and transmitter configurations without requiring precise placement or orientation specific to particular device models.
Solution Approach 2:
The system dynamically adjusts power transfer parameters based on real-time analysis of transmitter characteristic data and receiver capability data. By modifying transmission power levels, frequency, and other parameters according to detected conditions, the system maintains adaptability across different device placements and orientations while ensuring efficient power transfer.
3Reliability
If current wireless charging solutions are used, then power transfer can be achieved, but there is inadequate security to ensure power transfer is provided only to authorized devices
Solution Approach 1:
The patent introduces blockchain technology as an intermediary for secure authentication. Instead of complex direct device-to-device authentication protocols, the system uses blockchain-stored credentials as a trusted mediator. The transmitter device authenticates receivers by verifying their credentials against the blockchain, providing robust security without requiring complex authentication logic in each device.
Solution Approach 2:
The system uses cryptographic credentials stored on the blockchain as digital copies of device identities and authorization information. Rather than implementing complex hardware-based authentication mechanisms in each device, the system replicates security functionality through software-based credential verification against the blockchain, reducing device complexity while maintaining high security standards.
4Productivity
If existing wireless chargers are designed to charge specific electronic devices, then power transfer efficiency can be optimized, but the wireless transmitter is not capable of supplying power to multiple electronic devices with varying parameters
Solution Approach 1:
The patent implements dynamic capability analysis where the receiver device analyzes transmitter characteristic data in real-time and the transmitter adjusts its operation based on receiver capability data. This dynamic adaptation allows a single transmitter to efficiently serve multiple device types by adjusting parameters such as power level, frequency, and transmission mode based on the specific receiver's capabilities, maintaining high efficiency across diverse devices.
Solution Approach 2:
The system changes operational parameters based on the specific device being charged. By analyzing transmitter characteristic data and receiver capability data, the system dynamically adjusts power transfer parameters including transmission power, frequency, modulation scheme, and protocol selection to optimize efficiency for each device type while maintaining the ability to charge multiple different devices.
