Touchscreen Parameter Selection for Ultrasonic Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic testing environments face challenges in precisely selecting parameter values within large value ranges, particularly due to limited feedback from mechanical input components and the need for multiple hands or fingers to operate touchscreen interfaces, leading to operator errors and increased testing time.
Innovation Solution
The implementation of touchscreen interfaces with interactive controls that allow single-handed input via gestures, such as swipe and tap gestures, to dynamically display and select precise parameter values based on input time, speed, and direction, providing enhanced visual feedback and reducing the risk of operator error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanical input components (rotating hardware knobs) are used for precise value selection, then measurement precision is improved, but device complexity increases and ease of operation deteriorates due to requiring multiple hands or fingers
Solution Approach 1:
The patent replaces mechanical input components (rotating hardware knobs) with a touchscreen interface that uses gestural inputs. The mechanical system of physical knobs requiring multiple hands is substituted with a software-based touchscreen that can be operated with a single hand using gestures like taps, slides, and rotations, thereby improving ease of operation while maintaining precision through digital value selection mechanisms
2Device complexity
If touchscreen interfaces require multiple hands or fingers for operation, then device complexity is reduced, but ease of operation worsens due to operator errors and increased testing time
Solution Approach 1:
The patent segments the touchscreen interface into distinct interactive regions with specific gestural controls. Different portions of the touchscreen are assigned different functions (e.g., value selection, parameter navigation, confirmation), allowing operators to use a single hand for specific tasks without requiring multiple hands or fingers simultaneously, thus improving ease of operation while keeping the overall interface simple
3Ease of operation
If traditional mechanical input components are used, then ease of operation is improved for single-handed use, but productivity decreases due to increased testing time
Solution Approach 1:
The patent implements dynamic value selection mechanisms on the touchscreen that respond to gesture speed and duration. Fast gestures enable rapid value changes for experienced users, while slower gestures provide more precise control when needed. This dynamic response allows operators to efficiently configure parameters with minimal testing time while maintaining ease of single-handed operation, thereby improving productivity

AI summary
Systems, devices, and methods are provided for selecting a precise value within a large value range. Data received by an ultrasonic inspection device can include a range of values associated with one or more parameters to be configured for performing ultrasonic inspection of a test object. A control in a user interface of the ultrasonic testing device can be provided and can include a display portion displaying one or more parameters and one or more values within the range of values associated with the one or more parameters. The control can also include an interactive portion configured to receive a plurality of inputs. Based on the inputs, a selected value associated with a first parameter can be determined. The selected value associated with the first parameter can be displayed as a static display within the display portion of the control.
