Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate hierarchical architecture is implemented for data transmission, then data exchange capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the data transmission hierarchical architecture with the existing wireless power transmission protocol structure. By integrating data exchange capabilities into the power transmission framework through standardized message formats and phases, the system achieves enhanced adaptability without proportionally increasing complexity. The communication/control units in both transmission and reception devices handle multiple functions including power negotiation and data exchange within a unified architecture.
2Reliability
If buffer size negotiation is implemented through capability packets, then data transfer reliability is improved, but communication overhead increases
Solution Approach 1:
The patent implements buffer size negotiation during the initialization phase through capability packets exchanged between transmission and reception devices. By determining and agreeing upon buffer sizes before actual data transfer begins, the system ensures reliable data transmission without requiring continuous communication overhead during the transfer phase. The buffer sizes are pre-configured based on device capabilities and transfer requirements.
