Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies cannot effectively correlate visual and tactile texture measurements at corresponding positions on an object, as they detect these textures separately without positional correspondence.
Innovation Solution
An object texture measurement device that includes a visual detection unit for optical reading of surface characteristics using image sensors and a tactile detection unit for surface information, with a control system that adjusts and correlates the measurement positions of both units relative to the object, allowing simultaneous measurement of visual and tactile textures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual and tactile textures are detected separately using individual detection units, then each texture can be detected independently, but correspondence between respective positions cannot be obtained
Solution Approach 1:
The patent combines multiple detection units (visual detection unit with image sensors and tactile detection unit with contact sensors) into a single integrated measurement system. The control unit coordinates both detection units to simultaneously measure visual and tactile textures at corresponding positions on the object, thereby obtaining positional correspondence information that would be lost if measurements were taken separately.
2Adaptability or versatility
If multiple detection units are used to measure both visual and tactile textures, then comprehensive texture information can be obtained, but the device complexity increases
Solution Approach 1:
The integrated measurement system is designed with multiple detection units that serve different functions (visual detection and tactile detection) within a single device. The control unit coordinates these units to provide comprehensive texture measurement capabilities, making the device versatile while managing complexity through unified control architecture.
3Area of stationary object
If detection units are moved relative to the object to capture surface information, then comprehensive surface coverage is achieved, but measurement time increases
Solution Approach 1:
The measurement system continuously moves the detection units relative to the object to capture surface information across the entire measured surface area. The control unit coordinates the movement and data acquisition to ensure continuous measurement without interruption, thereby reducing total measurement time while achieving comprehensive surface coverage.

AI summary
An object texture measurement device includes a visual detection unit that detects a visual texture of an object, a tactile detection unit that detects a tactile texture of the object, and an acquisition unit that acquires a detection result of each of the visual detection unit and the tactile detection unit while relatively moving each of the visual detection unit and the tactile detection unit with respect to the object.
