Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ultrasonic testing methods are used to detect defects in large composite structures, then defect detection capability is achieved, but portability and infrastructure requirements are limited
Solution Approach 1:
The system segments the ultrasonic inspection process into multiple independent components: phased array transducers for signal transmission, portable data acquisition units, and wireless communication modules. This segmentation enables the system to be deployed in field conditions without extensive infrastructure while maintaining defect detection capabilities.
Solution Approach 2:
The patent replaces traditional mechanical scanning systems with phased array ultrasonic technology that uses electronic beam steering. This substitution eliminates the need for complex mechanical positioning infrastructure and enables portable deployment while maintaining measurement precision for defect detection.
2Measurement precision
If high-resolution defect visualization is achieved through detailed scanning, then measurement precision is improved, but inspection time increases
Solution Approach 1:
The system performs preliminary A-scan data acquisition across the entire inspection area before generating detailed C-scan visualizations. This preliminary action allows the system to identify regions of interest that require higher resolution analysis, thereby reducing the total inspection time while maintaining visualization precision where needed.
Solution Approach 2:
The patent applies partial action by generating full-resolution C-scan visualizations only for regions containing detected defects, rather than processing the entire inspection area at maximum resolution. This approach maintains measurement precision for defect characterization while significantly reducing the time required for data processing and visualization generation.
3Measurement precision
If multiple gate regions are analyzed for different depth ranges, then defect detection accuracy is improved, but data processing complexity increases
Solution Approach 1:
The system segments the ultrasonic signal analysis into multiple depth-specific gate regions, each processed independently to detect defects at different depths within composite layers. This segmentation improves detection accuracy by reducing signal overlap and interference, while the modular processing approach manages data processing complexity through systematic organization.
Solution Approach 2:
The patent transforms one-dimensional A-scan depth information into two-dimensional C-scan visualizations by processing multiple gate regions across different lateral positions. This dimensional transformation organizes complex multi-depth data into intuitive spatial representations, improving defect detection accuracy while providing a structured framework for data management.

AI summary
The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.
