Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution detection methods are used for parameter adjustments, then measurement precision is improved, but device complexity and installation space increase
Solution Approach 1:
The detection range is divided into multiple sub-ranges, with each sub-range assigned to a specific parameter value. The sensor element detects which sub-range the actuation position falls into, enabling precise parameter adjustment without requiring complex high-resolution detection systems. This segmentation approach allows accurate measurement while keeping the detection system simple.
2Measurement precision
If multiple sensors are used for high-resolution detection, then measurement precision is improved, but manufacturing cost and installation complexity increase
Solution Approach 1:
A single sensor element performs multiple functions: it detects the actuation position, determines which sub-range the position falls into, and identifies the corresponding parameter value. This multi-functional approach eliminates the need for multiple specialized sensors, reducing manufacturing complexity and installation requirements while maintaining high detection accuracy.
3Measurement precision
If complex control systems are used for parameter setting, then parameter adjustment precision is improved, but ease of operation deteriorates due to driver attention requirements
Solution Approach 1:
The sensor element automatically detects the actuation position and the control unit autonomously determines the corresponding parameter value based on the detected sub-range. This self-service mechanism eliminates the need for complex control algorithms and reduces the cognitive burden on the driver, as the system automatically interprets the user's input without requiring additional attention or complex interactions.
