Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing phased array ultrasonic testing (PAUT) systems require multiple passes over a material to obtain data from probes at different angles, increasing testing time and apparatus size, which can hinder testing in small spaces or complex geometries and increase setup time.
Innovation Solution
A phased array ultrasonic testing device with a coupling structure that allows parallel movement of two wedges supporting phased array probes, reducing the overall size and weight of the testing equipment and enabling simultaneous use of multiple probes at different angles without increasing setup time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate probe/holder assemblies are attached to the robotic device to obtain data at different angles, then the testing completeness is improved, but the overall size and weight of the testing apparatus increases
Solution Approach 1:
The patent combines multiple probe/holder assemblies into a single integrated holder assembly that can accommodate multiple probes at different angles simultaneously. This merging approach maintains the capability to obtain data at multiple angles while reducing the overall weight and size of the testing apparatus compared to using separate assemblies.
Solution Approach 2:
The holder assembly is designed as a universal platform that can accommodate multiple probes at different angular positions and orientations. This multi-functional design allows a single assembly to perform the function of multiple separate assemblies, reducing the overall apparatus weight while maintaining testing completeness.
2Adaptability or versatility
If multiple separate probe/holder assemblies are attached to the robotic device, then the angular coverage is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple probe/holder assemblies into a single integrated holder assembly with a coupling structure. This consolidation reduces device complexity by eliminating the need to manage multiple separate assemblies while maintaining the capability to achieve comprehensive angular coverage through multiple probes positioned at different angles within the single assembly.
3Loss of information
If multiple separate probe/holder assemblies are used, then the angular information completeness is improved, but the setup time increases
Solution Approach 1:
The patent combines multiple probe/holder assemblies into a single integrated holder assembly where multiple probes are positioned at different angles simultaneously. This approach reduces setup time because all angular configurations are prepared in advance within the single assembly, eliminating the need to attach and configure multiple separate assemblies sequentially.
Solution Approach 2:
The holder assembly is pre-configured with multiple probes positioned at different angular orientations before the testing operation. This preliminary arrangement of all required angular configurations allows for rapid deployment and reduces setup time compared to assembling multiple separate probe/holder assemblies during the testing preparation phase.
4Adaptability or versatility
If the robotic device is made larger to accommodate multiple assemblies, then the angular coverage is improved, but the ability to test in small spaces is reduced
Solution Approach 1:
The patent merges multiple probe/holder assemblies into a single compact holder assembly that maintains the capability to achieve comprehensive angular coverage. This consolidation significantly reduces the overall volume of the testing apparatus, enabling it to access and test materials in small or confined spaces where multiple separate assemblies would not fit.
