Scanning Tool With Open Operative Zone For Large Substrates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scanning devices, such as the X-Rite i1iO scanning table, are unsuitable for scanning large-sized sheet-like elements like ceramic tiles due to size and thickness limitations, requiring tiles to be cut into smaller pieces for scanning, which is time-consuming and generates dust, and cannot handle substrates thicker than 10 mm.
Innovation Solution
A tool that allows the scanning device to rest directly on the substrate, eliminating the need for a base and enabling scanning of large and thick substrates by defining an open operative zone for the spectrometer, with optional side appendages for stability and a vision device for accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the substrate is placed on the base of the scanning table, then the scanning device can acquire images, but the base covers the operative zone and cannot accommodate large or thick substrates
Solution Approach 1:
Instead of placing the substrate on the base as in conventional scanning tables, the invention inverts the relationship by having the support rest directly on the substrate. The spectrometer then scans from above through the open operative zone, eliminating the base obstruction and enabling scanning of large and thick substrates without size or thickness limitations.
2Area of stationary object
If the tile is cut into smaller portions to fit the base, then scanning can be performed, but the cutting operation is time-consuming and generates dust
Solution Approach 1:
The invention extracts and removes the base component from the scanning system, replacing it with a support that rests on the substrate. This elimination of the base allows the entire substrate, regardless of size, to be scanned without preprocessing cuts, thereby removing the time-consuming cutting operation and dust generation entirely.
3Measurement precision
If the spectrometer scans through the base, then images can be acquired, but the base obstructs the scanning path for large substrates
Solution Approach 1:
The invention inverts the conventional scanning arrangement by positioning the support on the substrate rather than the substrate on the base. This allows the spectrometer to scan through the open operative zone without base obstruction, maintaining measurement precision while accommodating substrates of any size or thickness.

AI summary
A tool for positioning a scanning device provided with a spectrometer comprises a support having a resting zone suitable for being rested onto a surface, a fixing arrangement for fixing the scanning device to the tool. The support is so dimensioned as to leave uncovered an operative zone in which the spectrometer is movable for acquiring an image provided on a substrate, so that the spectrometer can acquire the image while the support is resting directly on the substrate. The tool further comprises a vision device comprising a video camera for recording the image and a control unit that controls the video camera, the control unit being programmed to recognise pre-established points of the image recorded by the video camera.
