Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensors face challenges in setting an optimal data range that balances resolution and size, requiring user-induced specifications and complex software/hardware for interpretation, leading to inefficiencies and increased computational effort.
Innovation Solution
A sensor with a dynamic data range that automatically adjusts based on generated sensor values over time windows, increasing or decreasing the range as needed to optimize performance without manual input, using a counter to track values outside or within the range.

Engineering Contradiction Analysis
1Adaptability or versatility
If a larger data range is selected, then the sensor can detect a wider variety of values, but the resolution becomes coarser and worse
Solution Approach 1:
The patent implements a dynamic data range that can automatically adjust between different ranges (first data range with higher resolution, second data range with lower resolution) based on the detected sensor values. This allows the sensor to adapt its resolution to the current measurement needs, providing high resolution when values are within a smaller range and preventing saturation when values exceed the initial range.
Solution Approach 2:
The sensor changes the parameter of data range size dynamically by switching between a first data range and a second data range. When sensor values approach the boundaries of the current range, the system switches to an appropriate range, thereby changing the effective measurement scale and maintaining optimal resolution across varying measurement conditions.
2Device complexity
If the data range is fixed, then the sensor structure is simpler, but user-induced specification is required and interpretation of sensor values becomes more complex
Solution Approach 1:
The sensor system performs self-service by automatically selecting and switching between different data ranges based on the detected sensor values. The control device monitors the sensor values and autonomously determines when to switch between the first and second data ranges, eliminating the need for manual user specification and automatic interpretation of the appropriate range.
Solution Approach 2:
The system uses feedback from the sensor values to automatically adjust the data range selection. When sensor values approach the boundaries of the current data range, the control device receives this feedback and switches to an appropriate range, creating a closed-loop system that adapts to measurement conditions without user intervention.
3Ease of operation
If manual user specification of data range is required, then initial setup is needed, but this increases computational effort and may require additional software and hardware
Solution Approach 1:
The sensor system eliminates manual configuration by implementing self-service automatic data range selection. The control device automatically monitors sensor values and switches between data ranges based on predefined criteria, removing the need for manual user specification and reducing the complexity of software and hardware required for configuration and interpretation.
Data Source
AI summary
A sensor with a dynamic data range. The sensor generates sensor values at consecutive time points. The sensor is configured in such a way that the data range is subjected, after each time point, to a treatment corresponding to one of the following treatment options performed as a function of the generated sensor values, wherein the treatment options include:—increasing the data range if n of the generated sensor values are outside the data range during a first time window,—decreasing the data range if m of the generated sensor values are within the data range during a second time window, and—otherwise leaving the data range unchanged. A method for automatically adjusting a data range of such a sensor is also described.
