Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed delay value is used between transmission and reception clock signals, then the system structure is simple, but the control performance and flexibility are limited
Solution Approach 1:
The patent implements a dynamic delay control system where the delay between transmission and reception clock signals can be adjusted in real-time. A delay control signal is generated that dynamically modifies the delay amount, allowing the system to adapt to different operational requirements while maintaining a relatively simple overall structure through controlled dynamism.
Solution Approach 2:
The patent employs a feedback mechanism where the delay control signal is adjusted based on the difference between the transmission clock signal and reception clock signal. This feedback loop enables automatic optimization of the delay parameter, improving control flexibility without requiring complex manual adjustment mechanisms.
2Measurement precision
If additional compensation devices are added to improve delay control precision, then the measurement precision improves, but the device complexity and cost increase
Solution Approach 1:
The patent implements a self-adjusting delay control system where the radar apparatus automatically generates and adjusts the delay control signal based on its own internal clock signals. The system uses its own transmission and reception clock signals to generate the delay control signal, eliminating the need for external compensation devices while maintaining high measurement precision.
Solution Approach 2:
The patent replaces complex mechanical or hardware-based delay compensation mechanisms with an electronic signal processing approach. By using digital signal processing and electronic delay control, the system achieves high precision delay measurement without requiring additional physical compensation devices, thereby reducing overall system complexity.
