Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate detection mechanisms are used to detect rotation position and movement position, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions into a single detection body that simultaneously detects both the rotation position of the rotation section and the movement position of the moving section. This merging of detection functions reduces the number of separate detection mechanisms needed, thereby simplifying the overall device structure while maintaining comprehensive detection capabilities.
Solution Approach 2:
The detection body is designed with multi-functionality, serving as a universal detection component that can detect both rotational and linear movement parameters. This universal detection mechanism eliminates the need for separate specialized sensors for each type of movement, reducing device complexity while preserving measurement precision.
2Device complexity
If a simple detection configuration is used, then device complexity is reduced, but the ability to detect both rotation and movement positions is compromised
Solution Approach 1:
The patent merges multiple detection capabilities into a single integrated detection body that can simultaneously measure both rotation position and movement position. This consolidation achieves simplicity in device configuration while preserving comprehensive detection functionality through the multi-functional design of the detection body.
Solution Approach 2:
The detection body acts as an intermediary component that translates both rotational and linear movements into detectable signals. By positioning this intermediary detection mechanism along the center axis line, the system achieves comprehensive detection capability with a single unified component rather than multiple separate systems.
3Difficulty of detecting and measuring
If the detection body is positioned away from the center axis line, then detection coverage is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent positions the detection body along the center axis line, utilizing the axial dimension for detection. This dimensional positioning allows the detection body to effectively monitor both rotation and movement along the axis without requiring complex lateral positioning or additional spatial dimensions, thereby simplifying the overall structural arrangement.
Solution Approach 2:
By positioning the multi-functional detection body along the center axis line, the system achieves comprehensive detection coverage in a compact arrangement. The detection body's location on the center axis enables it to detect both rotational and linear movements without requiring offset positioning or additional structural complexity.
