Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for obtaining images of disc analysis or test results face challenges due to inconsistencies in the positioning of magnets between the disc and the feeding unit, leading to slope deviations in the captured images, which hinder accurate image recognition.
Innovation Solution
A method and apparatus that utilize a controller to align the positioning of magnets between the disc and the feeding unit by controlling the movement of the feeding unit along the radial direction of the disc, ensuring that the image obtainer can accurately capture the analysis result object without slope deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If magnets are used to fix the positioning of the disc, then the positioning accuracy is improved, but a difference between positionings of the magnets in the disc and feeding unit occurs leading to slope deviations
Solution Approach 1:
The patent replaces the mechanical magnetic positioning system with an optical positioning system. Instead of relying on magnetic attraction between magnets in the disc and feeding unit, the system uses an image obtainer (camera) to detect the position of a reference mark on the disc, and a controller calculates positioning information based on the detected mark position. This substitution eliminates slope deviations in captured images by providing precise optical positioning without the alignment issues inherent in magnetic systems.
2Productivity
If the feeding unit moves to capture images, then image acquisition is enabled, but slope deviations occur due to magnet positioning differences
Solution Approach 1:
The patent replaces mechanical magnetic alignment with optical detection and computational positioning. The image obtainer captures images of a reference mark on the disc, and the controller calculates the precise position based on the detected mark coordinates. This allows the feeding unit to move freely for image acquisition while maintaining precise alignment through optical feedback rather than mechanical magnetic attraction.
Solution Approach 2:
The system implements feedback control by detecting the position of a reference mark on the disc using an image obtainer, calculating positioning information based on the detected position, and using this information to correct alignment. This feedback loop ensures that even when the feeding unit moves for image acquisition, the positioning remains accurate by continuously referencing the mark position and adjusting accordingly.
