Multi-Point Touch Interface for Eddy Current Impedance Plane Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable eddy current inspection systems require time-consuming and complex manipulation of impedance planes for defect detection, involving multiple steps and parameters, which can be cumbersome and inefficient, especially with interactions between vertical gain and rotation.
Innovation Solution
A multi-point touch screen interface allows for direct manipulation of eddy current impedance plane signals, reducing the number of steps required and providing a more intuitive operation by integrating button controls and displayed parameters, enabling simultaneous modification of multiple parameters with single touch screen operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu-based controls with multiple buttons and knobs are used for impedance plane manipulation, then comprehensive parameter control is achieved, but operation time and complexity increase significantly
Solution Approach 1:
The patent replaces mechanical knobs and button-based control systems with a graphical user interface that displays the impedance plane directly. Users interact with visual representations of impedance parameters through drag-and-drop or click operations on the displayed plane, substituting mechanical manipulation with graphical interaction. This reduces the number of steps required to adjust parameters while maintaining comprehensive control over impedance plane manipulation.
2Device complexity
If multiple separate controls are provided for each impedance parameter, then precise individual parameter adjustment is possible, but the number of controls and interface complexity increase
Solution Approach 1:
The graphical impedance plane display serves multiple functions simultaneously: it visualizes the current impedance state, allows selection of specific parameters through direct interaction with the display, and provides adjustment controls integrated within the same interface. This multi-functional approach consolidates what would otherwise require separate controls for each parameter, reducing overall interface complexity while maintaining precise adjustment capabilities through contextual interaction with the visualized impedance data.

AI summary
A touch screen is disclosed which responds to a user's touch for re-drawing, re-scaling, re-translating and re-positioning an impedance plane signal received from non-destructive testing equipment, such as an eddy current sensor. The impedance plane is manipulated by slidingne, two or more fingers simultaneously to an end position to effectuate a complete re-drawing operation of the image.
