Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If zero power consumption terminals report data to network devices using traditional communication methods, then data transmission can be achieved, but data security cannot be ensured due to eavesdropping risks
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting signal characteristics (amplitude, frequency, phase) across different time periods. The energy supply signal uses varying parameters to embed security information, while the data signal parameters are modified based on the energy supply signal parameters, creating a time-varying secure communication scheme that prevents eavesdropping without requiring complex additional hardware
Solution Approach 2:
The patent implements dynamics by making the communication signal parameters time-dependent and adaptive. The energy supply signal parameters change over time periods, and the data signal parameters are dynamically adjusted according to the energy supply signal, creating a dynamic security mechanism that responds to different transmission phases without requiring real-time interaction between devices
2Reliability
If varying parameters are used across multiple time periods for signal generation, then security against eavesdropping is enhanced, but signal processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the communication process into distinct time periods, where each period has specific signal parameter characteristics. The energy supply signal is segmented into multiple time periods with different parameters, and the data signal processing is similarly segmented, allowing complex security operations to be broken down into manageable time-based segments that simplify overall processing
Solution Approach 2:
The patent implements preliminary action by pre-establishing the relationship between energy supply signal parameters and data signal parameters before actual data transmission. The varying parameters are predetermined and configured in advance, allowing the terminal to generate secure signals without real-time complex calculations, thus reducing processing complexity during actual communication
