Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing methods are used to identify solid phase substances in core fractures, then identification can be performed, but the core is damaged and identification accuracy is low
Solution Approach 1:
The patent creates a virtual grayscale template representing the core fracture filled with reference solid phase substances. This template serves as a copy or model that can be compared against the actual core scan without physically interacting with or damaging the core sample. The template is generated by filling a virtual core fracture model with reference substances and scanning it to obtain grayscale values, which are then stored as a template for comparison.
Solution Approach 2:
The patent replaces physical mechanical examination methods with computed tomography (CT) scanning and image processing. Instead of using mechanical means to extract or examine the core physically, the system uses non-contact X-ray scanning to obtain grayscale images, then applies image processing and comparison algorithms to identify solid phase substances. This substitution eliminates mechanical damage while maintaining identification capability.
2Loss of information
If the core is scanned to identify solid phase substances, then identification can be performed, but the core structure may be compromised
Solution Approach 1:
The patent creates a virtual grayscale template representing the core fracture filled with reference solid phase substances. This template serves as a copy or model that can be compared against the actual core scan without physically interacting with or damaging the core sample. The template is generated by filling a virtual core fracture model with reference substances and scanning it to obtain grayscale values, which are then stored as a template for comparison.
Solution Approach 2:
The patent introduces a grayscale template as an intermediary between the core scan and the identification process. The template acts as a reference model that mediates the comparison, allowing identification of solid phase substances without direct physical manipulation of the core. The template contains pre-established grayscale value ranges for different substances, serving as a intermediary reference standard.
