Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic testing devices require a heavy workload for planning and testing on subjects with complicated shapes or those with interferers, as non-testable ranges need to be manually determined under multiple conditions.
Innovation Solution
An ultrasonic testing device and method that uses a scanner with an ultrasonic probe, an information acquirer, interference analyzer, and scan path planner to automatically calculate and plan a scan path to avoid interference ranges, reducing the workload by calculating non-testable ranges and planning an effective scan path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual determination of non-testable ranges is performed under multiple testing conditions, then testing accuracy is improved, but workload increases significantly
Solution Approach 1:
The system performs automatic scan path planning by having the scan path planner autonomously calculate optimal paths and determine non-testable ranges based on interference analysis, eliminating the need for manual determination while maintaining testing accuracy
Solution Approach 2:
The patent replaces manual mechanical operations with automated computational processes. The interference analyzer and scan path planner use computer-based algorithms to automatically calculate interference ranges and generate scan paths, substituting human manual work with automated information processing
2Productivity
If automatic scanning is adopted for wide scan ranges, then testing efficiency is improved, but complexity of planning scan path increases
Solution Approach 1:
The patent introduces an interference analyzer as an intermediary component between the subject geometry data and the scan path planner. This intermediary automatically identifies interference ranges and provides this information to the scan path planner, simplifying the overall planning process while maintaining automation
Solution Approach 2:
The patent divides the scan path planning process into distinct functional segments: information acquisition, interference analysis, and scan path planning. This segmentation allows each component to focus on a specific task, reducing the complexity of the overall system while enabling automatic scanning

AI summary
An ultrasonic testing device uses a scanner, employing an ultrasonic probe for scanning, to ultrasonically test a desired tested range of a subject, and includes: an information acquirer to acquire data on the subject, the scanner, the ultrasonic probe, and testing conditions; an interference analyzer to use the data acquired by the information acquirer to calculate one or more interference ranges between the subject, having one or more interferers, and the scanner, having the ultrasonic probe attached thereto, and a scan path planner to use the one or more interference ranges to calculate a scan path of the ultrasonic probe, based on the acquired data on the testing conditions, so as to avoid the one or more interference ranges.
