Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection using vernier caliper is used to measure surface flatness, then the measurement can be performed, but the measurement error is large and accuracy is poor
Solution Approach 1:
The patent replaces the manual vernier caliper mechanical measurement system with an automated detection system comprising a detector, telescopic arm, and pressure sensor. The detector moves along the telescopic arm to automatically measure surface flatness at multiple positions, eliminating manual operation errors and achieving higher measurement precision and reliability.
Solution Approach 2:
The detection system performs self-measurement by automatically positioning the detector along the telescopic arm to contact the square rod surface. The pressure sensor automatically records surface flatness data without requiring inspector judgment, enabling the system to serve itself in completing the measurement task with consistent accuracy.
2Productivity
If manual inspection is used to measure surface flatness, then the process can be completed, but the inspection speed is low and work efficiency is reduced
Solution Approach 1:
The telescopic arm continuously moves the detector along the square rod surface without interruption, performing measurement at multiple positions in sequence. This continuous automated measurement process eliminates the intermittent nature of manual inspection, significantly increasing inspection speed and productivity while maintaining measurement quality.
Solution Approach 2:
The detection system employs dynamic components including the telescopic arm that can extend and retract, and the detector that moves along the arm to reach different measurement positions. This dynamic configuration enables rapid adaptation to different measurement requirements and accelerates the inspection process compared to static manual measurement.
3Adaptability or versatility
If only one side of the square rod is detected at a time, then the detection setup is simple, but all four sides cannot be detected simultaneously requiring multiple measurements
Solution Approach 1:
The detector assembly with telescopic arm is designed as a universal measurement tool that can detect all four sides of the square rod. By rotating the square rod to different positions, the same detector structure measures surface flatness on each side, achieving multi-functionality without requiring separate detection devices for each face.
Solution Approach 2:
The detection process is segmented into multiple measurement stages, with the detector measuring one side at a time while the square rod is rotated to different orientations. This segmentation allows comprehensive coverage of all four sides using a single detection assembly, balancing measurement completeness with device simplicity.
