Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional high-frequency clock signal sampling is used to identify pulse waveforms, then data transmission accuracy is improved, but power consumption increases and processing efficiency deteriorates
Solution Approach 1:
The patent changes the sampling parameter from using high-frequency clock signals to using the differential signal's own clock edge, fundamentally altering how sampling is performed. This parameter change enables accurate waveform identification without requiring externally generated high-frequency clock signals, thereby reducing power consumption while maintaining data transmission accuracy.
Solution Approach 2:
The patent employs self-service by utilizing the differential signal's inherent clock information to perform sampling. Instead of requiring external high-frequency clock signals to drive the sampling process, the system uses the clock edge embedded within the differential signal itself, making the sampling process self-sustaining and eliminating the need for additional power-intensive clock generation circuits.

3Measurement precision
If external high-frequency clock signals are used for sampling, then sampling accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts the clock information directly from the differential signal itself, removing the dependency on external high-frequency clock signals. By taking out the clock function from the external environment and embedding it within the signal processing path, the system eliminates the need for separate clock generation and distribution circuits, thereby reducing device complexity while maintaining sampling accuracy.
Solution Approach 2:
The patent makes the differential signal serve multiple functions: it carries both data information and clock information. This multi-functionality eliminates the need for separate dedicated clock signals, reducing the overall complexity of the system while maintaining accurate sampling capability.
