Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surface texture measuring devices struggle with accurate measurements at non-horizontal angles due to the need for time-consuming calibration and operator skill, often resulting in uncorrected measurements when environmental conditions or operator expertise are inadequate.
Innovation Solution
A surface texture measuring device and system equipped with a posture detecting sensor and preloaded correction values, allowing for rapid and accurate correction of measurement results by identifying the measured posture and applying corresponding correction values, and optionally incorporating a vibration detecting sensor to halt measurements during excessive vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration measurement is performed using a roughness standard specimen in the actual measurement posture, then measurement accuracy is improved, but measurement time increases excessively
Solution Approach 1:
The system performs calibration measurements for multiple postures in advance and stores the results as correction values in a lookup table. During actual measurement, the system only needs to detect the current posture and retrieve the corresponding correction value, eliminating the need for time-consuming on-site calibration while maintaining measurement accuracy.
2Measurement precision
If correction values are preloaded for multiple postures, then measurement accuracy is improved, but operator skill requirement increases
Solution Approach 1:
The system automatically detects the measurement posture using a posture detection sensor and autonomously selects and applies the corresponding correction value from the preload table. This automation eliminates the need for operators to manually identify postures or select correction values, reducing skill requirements while maintaining measurement accuracy.
3Measurement precision
If manual posture identification is required, then correction can be applied, but operator error increases and selection time increases
Solution Approach 1:
The system replaces manual posture identification with an automated posture detection sensor that objectively detects and identifies the measurement posture. This substitution eliminates human judgment errors and reduces selection time, while the systematic approach ensures accurate matching of correction values to postures.

AI summary
A surface texture measuring device according to the present invention includes a surface texture detecting component that outputs measurement results for a surface texture of a measurable object, where the measurement results are recognized as a change in the movement of a contact pin of a detector when tracing a surface of the measurable object with the contact pin; a posture detecting sensor that detects a measured posture, which is a posture at the time of measurement by the detector; a memory component that is preloaded with correction values corresponding to each of a plurality of postures; and a correcting component that compares the measured posture with the plurality of postures stored in the memory component, and corrects the measurement results using a correction value that corresponds to a posture equivalent to the measured posture.
