Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If ultrasound inspection is used for anisotropic and composite materials, then inspection capability is provided, but measurement precision deteriorates due to signal distortion
Solution Approach 1:
The patent applies a transfer function that modifies the ultrasound signal parameters to compensate for distortion caused by anisotropic material properties. This involves adjusting the signal characteristics based on the known acoustic properties of the material to restore accurate defect characterization.
Solution Approach 2:
The patent replaces direct mechanical measurement of defect dimensions with a computational approach using transfer functions and three-dimensional modeling. Instead of relying on distorted acoustic signals alone, the system uses mathematical models to correct and interpret the ultrasound data.
2Difficulty of detecting and measuring
If conventional UT inspection methods are used for composite materials, then inspection is performed, but reliability deteriorates due to false rejections
Solution Approach 1:
The patent incorporates feedback mechanisms where the system uses the known acoustic properties of composite materials to continuously adjust and correct the inspection results. The transfer function provides feedback correction based on material characteristics to eliminate false rejections.
Solution Approach 2:
The patent introduces a transfer function as an intermediary between the ultrasound signal and the defect characterization. This intermediary component mediates the distortion caused by anisotropic materials, providing a bridge between raw acoustic data and accurate defect measurements.
3Difficulty of detecting and measuring
If multiple UT scans from different orientations are performed, then comprehensive inspection coverage is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple ultrasound scan datasets from different orientations into a single three-dimensional inspection model. This consolidation approach combines the comprehensive coverage of multiple scans while managing complexity through integrated processing rather than separate analyses.
