Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing signal processing methods are used to calculate material parameters, then the device can operate with simple processing, but the precision and accuracy of object information derivation is insufficient
Solution Approach 1:
The device segments the complex measurement problem into distinct functional modules: a transmitter for sending signals, a receiver for capturing reflected signals, an evaluation unit for calculating parameters, and a computer for model-based comparison. This segmentation allows each component to specialize in specific tasks, improving overall measurement precision while making the complex system more manageable and maintainable
Solution Approach 2:
The system performs preliminary actions by pre-storing model data and comparison parameters in the computer's memory before actual measurements. The evaluation unit pre-calculates expected parameter values based on stored models, enabling faster and more accurate real-time object analysis without increasing operational complexity
2Reliability
If model-based comparison parameters are used to improve accuracy, then object information can be derived more precisely, but the calculation complexity and processing time increase
Solution Approach 1:
The computer stores pre-calculated model data and comparison parameters in its memory before actual measurements are taken. During operation, the evaluation unit quickly compares measured parameters against these pre-stored models, significantly reducing calculation time while maintaining high accuracy in object information derivation
Solution Approach 2:
The system implements feedback by comparing calculated parameters with model-based comparison parameters and using the deviations to refine object characterization. This feedback mechanism improves reliability by continuously validating measurements against established models, ensuring accurate material parameter derivation without requiring repeated complex calculations
