Oscilloscope Operating Point Visualization for Intuitive Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oscilloscopes lack intuitive and easy control mechanisms, as operators often encounter operating points beyond allowable ranges without clear understanding of the constraints, leading to frustration and confusion.
Innovation Solution
A method and oscilloscope design that detect and process waveform axis scale and record length input values to determine allowable operating ranges, displaying these ranges on the oscilloscope display, allowing operators to set valid points and visualize changes, with a processor configured to assess inputs against predetermined operating mode limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the oscilloscope provides detailed operating mode limits and constraints to operators, then the understanding of oscilloscope capabilities is improved, but the device complexity increases
Solution Approach 1:
The graphical user interface provides real-time feedback by displaying the current operating point and allowable operating ranges. When operators adjust settings, the system immediately updates the display to show whether the new settings are within valid ranges, providing continuous feedback without requiring deep understanding of underlying constraints.
Solution Approach 2:
The patent introduces an intermediary graphical representation system that translates complex operating mode limits into visual displays. The processor acts as an intermediary, calculating allowable ranges based on multiple constraints and presenting them as simple graphical boundaries, shielding operators from complexity while maintaining information transparency.
2Ease of operation
If the oscilloscope displays detailed operating ranges and limits, then the ease of operation is improved, but the loss of time for processing and displaying information increases
Solution Approach 1:
The system pre-calculates and stores allowable operating ranges for different operating modes before operators need them. When operators launch the oscilloscope or switch modes, the permissible ranges are already computed and ready for immediate display, eliminating real-time calculation delays during operation.
Solution Approach 2:
The patent displays only the essential information needed for operation - the allowable operating ranges and current position - rather than computing and displaying all possible constraint details. This partial display approach provides sufficient guidance for operation while minimizing processing and display time.
