TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If separate coils for power reception and data communication are provided, then wireless power supply and high-speed data communication can be achieved without interference, but device complexity increases
Why choose this principle:
The patent divides the wireless communication function into separate coils: one coil dedicated for power reception and another coil dedicated for data communication. This segmentation prevents electromagnetic interference between power transmission and data transmission, enabling both functions to operate reliably without mutual interference.
Principle concept:
If time division and phase-shifting mechanisms are used to prevent electromagnetic wave interference, then high-speed data communication is enabled, but device complexity increases
Why choose this principle:
The patent employs time division multiplexing where power reception and data communication are performed in alternating time slots. During one period, power is transmitted; during the next period, data is communicated. This periodic action prevents electromagnetic interference while enabling high-speed data transfer.
