Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a position detector is added to existing adjusting means, then position detection capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the position detector and actuating drive into a single integrated unit. The detector is mounted on the actuating drive housing, and the detector's evaluation unit is electrically connected to the actuating drive's control unit, creating a unified component that performs both actuation and position detection functions, thereby avoiding additional separate components and reducing overall system complexity
Solution Approach 2:
The actuating drive is designed to serve multiple functions: it provides the actuating force for mirror adjustment and simultaneously houses the position detector and its evaluation unit. This multi-functional design allows the same structural element to perform both mechanical actuation and positional measurement, eliminating the need for separate dedicated components
2Measurement precision
If multiple toothed ring segments are used for both actuation and detection, then position detection precision is improved, but manufacturing complexity increases
Solution Approach 1:
The toothed ring is divided into two distinct segments: a first toothed ring segment with a larger radius that engages with the actuating drive's pinion for mechanical actuation, and a second toothed ring segment with a smaller radius that engages with the detector's pinion for position detection. This segmentation allows each segment to be optimized for its specific function while simplifying the overall manufacturing process compared to a single complex gear system
Solution Approach 2:
Different segments of the toothed ring are designed with different local properties: the first segment has teeth optimized for high-torque actuation engagement, while the second segment has teeth optimized for precise detection engagement. Each segment can be manufactured with specific tolerances and tooth profiles suited to its function, rather than requiring the entire ring to meet the most stringent requirements
