Solution Overview
Problem
Current methods for evaluating the strength properties of cores, such as sand cores, are inadequate as they rely on test pieces, which is not a comprehensive quality control approach.
Innovation Solution
A core inspection device equipped with a color sensor that detects color components of the core's surface and compares these measurements with predetermined thresholds to determine the strength properties, allowing for accurate evaluation of the core's baked degree and overall strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inspection is conducted using test pieces, then the inspection process is simple, but the quality control is not substantial and does not reflect actual core strength
Solution Approach 1:
The patent replaces mechanical strength testing with an optical detection system. A color sensor detects color components of the core surface, and a determination unit compares these measurements with thresholds to evaluate strength properties. This substitution of mechanical testing with optical measurement achieves substantial quality control without the complexity of physical strength tests.
2Measurement precision
If the color sensor is placed closer to the core for better measurement accuracy, then the measurement precision improves, but the distance control becomes more difficult
Solution Approach 1:
The patent employs a feedback mechanism where a distance sensor continuously measures the distance between the color sensor and the core. Based on this measurement, a movement unit automatically adjusts the position of the color sensor to maintain a predetermined optimal distance. This closed-loop feedback system ensures measurement precision while eliminating manual distance control difficulties.
3Measurement precision
If multiple color components are measured and combined for determination, then the strength evaluation accuracy improves, but the determination complexity increases
Solution Approach 1:
The patent measures multiple color components (R, G, B values) of the core surface and creates a composite determination by comparing these measurements with pre-established thresholds. The determination unit integrates multiple color component measurements to evaluate strength properties, achieving accurate evaluation through systematic combination of multiple parameters rather than relying on a single measurement.

AI summary
A core inspection device for inspecting a core, the device including a color sensor configured to detect a measured value of each color component of the color of the surface of the core, and a determination unit configured to compare the measured value of at least one color component detected by the color sensor with a threshold prepared corresponding to the at least one color component, thereby determine if a strength property of the core is acceptable or not.
