Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a zero power consumption terminal reports data to the network device using traditional communication methods, then the data transmission can be completed, but the security of the reported data cannot be ensured due to eavesdropping risks
Solution Approach 1:
The patent applies parameter changes by varying the energy supply signal parameters (such as amplitude, frequency, or phase) across different time periods. This creates a time-varying signal that embeds data while maintaining security, as eavesdroppers cannot easily decode the varying parameters without knowledge of the specific parameter sequence used
Solution Approach 2:
The patent implements periodic action by dividing the energy supply signal transmission into multiple time periods, where each period uses different signal parameters. This periodic variation with changing parameters enables secure data transmission through the energy supply signal while maintaining a structured communication framework
2Reliability
If time-varying energy supply signals with varying parameters are used to secure data transmission, then data security is improved, but the complexity of the communication method increases
Solution Approach 1:
The patent applies segmentation by dividing the overall signal transmission into multiple discrete time periods, with each period using specific parameter configurations. This segmentation simplifies the generation process compared to creating a continuously varying complex signal, as each segment can be independently generated and managed
Solution Approach 2:
The patent implements dynamics by making the energy supply signal parameters time-varying rather than static. The parameters change across different time periods according to a predetermined pattern, enabling secure communication while maintaining manageable system complexity through structured temporal variation
3Ease of operation
If traditional energy supply signals are used for zero power consumption terminals, then the terminal can receive energy and communicate, but the data transmitted can be easily analyzed by eavesdroppers
Solution Approach 1:
The patent applies parameter changes by varying the energy supply signal parameters across different time periods, making the signal unpredictable to eavesdroppers. This maintains the energy supply functionality for legitimate terminals while preventing easy analysis of the modulated data by unauthorized parties
