Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wireless power transmission is performed using electromagnetic waves, then power transmission capability is improved, but interference with other wireless communication systems occurs
Solution Approach 1:
The system performs preliminary authentication with an authentication server before allowing power transmission. The control circuitry verifies that the electronic apparatus is registered and authorized, and only then permits the power transmitter to operate. This preliminary check prevents unauthorized devices from causing interference while allowing authorized devices to transmit power normally.
Solution Approach 2:
An authentication server acts as an intermediary between the power transmitter and the electronic apparatus. The server verifies registration information and provides authentication results, mediating the authorization process. This intermediary ensures that only properly registered devices can initiate power transmission, thereby reducing unauthorized interference with wireless communication systems.
2Extent of automation
If authentication with authentication server is implemented, then control over power transmission is improved, but system complexity increases
Solution Approach 1:
The electronic apparatus automatically performs authentication with the authentication server without requiring manual intervention. The control circuitry autonomously communicates registration information to the server, receives authentication results, and automatically controls the power transmitter based on these results. This self-service approach simplifies user interaction while maintaining systematic control.
