Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal lines of equal length are provided between the signal generator and radars, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the transmission of high-frequency signals and control signals into a single signal line by synthesizing them. This merging eliminates the need for separate signal lines for each type of signal, thereby reducing wiring complexity while maintaining the ability to provide equal-length paths for accurate phase alignment in MIMO radar operations
2Measurement precision
If signal lines of equal length are provided between the signal generator and radars, then detection accuracy is improved, but system cost increases
Solution Approach 1:
The patent merges multiple signal transmissions into a single synthesized signal line, reducing the total amount of wiring required. This consolidation directly lowers material costs and assembly complexity, making the system more cost-effective while still achieving the necessary equal-length signal paths for accurate detection
3Ease of operation
If separate signal lines are used for high-frequency and control signals, then signal transmission is simplified, but wiring complexity increases
Solution Approach 1:
The patent introduces a signal synthesizer as an intermediary device that combines high-frequency signals and control signals into a single synthesized signal. This intermediary component allows both types of signals to be transmitted through one wire, reducing wiring complexity while maintaining the functional separation and clarity of signal transmission
