Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless power transmitter transmits only a single data stream during power transfer, then the system maintains simple communication structure, but data transport efficiency is insufficient and communication stability is poor
Solution Approach 1:
The patent segments the communication channel into multiple independent data streams (first data stream and second data stream). Each stream can be transmitted simultaneously through the wireless power transmission medium, allowing parallel data communication. This segmentation enables the system to handle multiple types of data (e.g., control signals and application data) concurrently, thereby improving data transport efficiency without requiring separate physical communication channels.
Solution Approach 2:
The wireless power transmission medium is designed to serve multiple functions: it simultaneously transmits power and carries multiple data streams. The patent enables the power transmission channel to function as a universal communication medium that can handle different types of data traffic (control commands, status information, application-specific data) through multiplexing techniques, eliminating the need for dedicated separate communication channels.
2Reliability
If multiple data streams are transmitted simultaneously through the wireless power transmission medium, then data communication stability is improved, but signal interference between streams increases
Solution Approach 1:
The patent employs periodic modulation techniques for transmitting multiple data streams through the wireless power medium. By using time-division multiplexing or periodic frequency modulation, different data streams are transmitted in alternating time slots or at different periodic frequencies. This periodic action allows the receiver to distinguish between different streams through synchronization, maintaining communication stability while managing signal interference through structured transmission patterns.
