Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to analyze the trajectory of a moving object, then measurement precision can be achieved, but processing cost and difficulty in obtaining and analyzing data increase
Solution Approach 1:
The system divides the measurement process into distinct phases: approach phase (using distance sensor for initial positioning and ready state notification) and measurement phase (using radar for trajectory analysis). This segmentation allows each phase to use optimized sensors, reducing overall system complexity while maintaining precision.
Solution Approach 2:
The distance sensor performs preliminary measurement to determine if the object is within the predetermined range before initiating radar measurement. The ready state notification is generated in advance to guide the user on proper object positioning, simplifying the subsequent radar data acquisition process.
2Measurement precision
If traditional analysis methods are used, then measurement accuracy can be maintained, but ease of operation and user convenience deteriorate
Solution Approach 1:
The system provides real-time feedback through ready state notification (visual, auditory, or light signals) to guide users on proper object positioning. This feedback mechanism simplifies operation by automatically adjusting the measurement state based on object distance, eliminating the need for manual range adjustment.
Solution Approach 2:
The system automatically determines when the object is within the measurement range and generates ready state notifications without user intervention. The distance sensor continuously monitors object position and autonomously triggers the appropriate measurement mode, making the system self-adjusting and easier to operate.
3Measurement precision
If comprehensive measurement capabilities are implemented, then analysis accuracy improves, but device portability and production cost reduce
Solution Approach 1:
The system uses a single radar device that can perform multiple functions: measuring distance, detecting object position, and analyzing flight characteristics. This multi-functionality eliminates the need for separate specialized sensors, reducing production cost while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The system changes the operational parameters of the radar based on the measured distance. When the object is within the predetermined range, the radar switches to detailed trajectory analysis mode. This parameter adjustment allows the same hardware to provide different levels of measurement precision as needed, optimizing cost-performance ratio.
