Dynamic Window Display for Real-Time Measurement Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for representing dynamic processes in measurement and control technology lack clarity and understandability, especially when dealing with rapidly changing measured values, making it difficult to determine if these values remain within predetermined limits.
Innovation Solution
A method and device that use an electronic measuring and control device to display a window representing a predeterminable time span and limits, where the measurement curve is shown within this window if it stays within the specified limits, allowing for real-time monitoring and ending the measurement when the criterion is met, with the option to display the mean value if the criterion is fulfilled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic processes are monitored using traditional display methods, then measurement data can be captured, but the clarity and understandability of the representation deteriorates when values change sharply
Solution Approach 1:
The display is segmented into a moving window that shows only the latest measurement segment within a defined time span, rather than displaying the entire measurement curve. This segmentation allows personnel to focus on the current relevant data portion, improving clarity and understandability when values change sharply.
Solution Approach 2:
The display window is made dynamic by dragging it along with the current measurement point in real-time. This dynamic adjustment ensures that the window always positions itself to show the most relevant recent measurements, maintaining clarity and understandability as the measurement process progresses.
2Reliability
If the entire measurement curve is displayed, then complete data is available, but the ability to quickly determine if values are within limits deteriorates
Solution Approach 1:
The measurement data is segmented into a focused window showing only the latest time span of measurements. This allows personnel to quickly assess whether current values are within limits without reviewing the entire historical data, significantly reducing the time needed for compliance assessment while maintaining reliability through continuous updating of the window.
Solution Approach 2:
The display provides immediate visual feedback by updating the window position and content in real-time as measurements are taken. This feedback mechanism allows personnel to quickly determine limit compliance without manual analysis of complete data sets, reducing assessment time while maintaining accurate monitoring.
3Loss of information
If horizontal limit lines are used as in prior art, then limit values are indicated, but the ability to visually determine if measured values remain within limits during measurement deteriorates
Solution Approach 1:
The limit indication is made dynamic by moving the window along with the current measurement point, creating a dynamic visual frame that adapts to the measurement process. This dynamic approach makes it easier to detect and measure limit compliance visually, as the window continuously updates to show the current context of measurements relative to the limits.
Solution Approach 2:
The display provides local quality by focusing the window on the specific segment of the measurement curve that is currently relevant, rather than uniformly displaying the entire curve. This localized view with its moving window makes it easier to detect whether local measurements are within limits, improving the ease of detection while maintaining complete limit value indication through continuous updating.

AI summary
The method involves monitoring a measured variable during measurement by using a display unit (14). Determination is made whether changes in the measured variable lie within preset limits during a predetermined time interval, which extends up to actual measuring time points. A window is displayed on the display unit, where dimensions of the window correspond to the predetermined time interval and the preset limits. The window is drawn along with the actual measuring time points during the measurement. An independent claim is also included for a device for graphically displaying dynamic procedures.
