Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light section sensor is used at different inclinations, then installation flexibility is improved, but measurement accuracy deteriorates due to coordinate distortion
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the coordinate system parameters through coordinate transformation. When the sensor inclination changes, the system transforms the measurement coordinates from the sensor's coordinate system to the object's coordinate system using transformation matrices, thereby maintaining measurement accuracy across different installation angles
Solution Approach 2:
The patent introduces an intermediary coordinate transformation process between the sensor measurement and the final output. The coordinate transformation device acts as a mediator that converts coordinates from the sensor's inclined coordinate system to the object's reference coordinate system, eliminating the direct impact of inclination on measurement accuracy
2Measurement precision
If coordinate transformation is implemented to compensate for inclination, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with computational coordinate transformation. Instead of physically adjusting the sensor to maintain perpendicular alignment, the system uses mathematical transformation matrices to correct for inclination, substituting mechanical complexity with computational processing
Solution Approach 2:
The system performs self-correction through automatic coordinate transformation. The coordinate transformation device automatically compensates for inclination effects using the known sensor orientation parameters, eliminating the need for manual calibration or external intervention to maintain accuracy
