Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal and liquid meters have complex human-machine interfaces that are not user-friendly and costly, requiring manual intervention for calibration and display switching, leading to operational inefficiencies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex human-machine interface with operating buttons is used, then the meter can be controlled and calibrated, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent removes the physical operating buttons and complex interface elements from the meter, extracting only the essential display function. The display device shows information automatically based on measured values, eliminating the need for manual interaction while reducing device complexity and manufacturing cost.
Solution Approach 2:
The display device operates autonomously by automatically selecting and displaying relevant information based on the current measured values. The system self-regulates what to display without user intervention, making the meter user-friendly while minimizing the interface complexity.
2Productivity
If manual intervention is required for calibration and display switching, then precise control is achieved, but productivity decreases and time is lost
Solution Approach 1:
The display device automatically determines what information to display based on the measured values from the measuring devices. It autonomously switches between displaying current measured values and calibration information without requiring manual intervention, thereby increasing productivity and eliminating time loss associated with manual operations.
Solution Approach 2:
The system continuously monitors measured values and uses this feedback to automatically adjust the display content. When measured values indicate normal operation, current values are displayed; when calibration is needed, calibration information is automatically shown, optimizing operational efficiency without manual input.
3Loss of information
If the display always shows current measured values, then operational information is available, but calibration information is not displayed when needed
Solution Approach 1:
The display content dynamically changes based on the current operational state and measured values. The system adaptively switches between displaying current measured values and calibration information, ensuring that the most relevant information is always accessible while maintaining complete information availability.
Solution Approach 2:
The display behavior changes based on parameter thresholds of the measured values. When measured values fall within normal ranges, current values are displayed; when they indicate calibration needs, the display automatically switches to show calibration information, ensuring both information completeness and ease of access.

AI summary
A method for displaying information on a display device (4) of a measuring instrument comprises measuring at least one measurand, displaying at least one current measured value of at least one measurand on the display device (4) and displaying at least one metrological information on the display device (4) if at least one current measured value of at least one measurand is less than a corresponding predetermined threshold value.
