Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems for determining the distance and flow speed of liquids require separate systems for distance detection and flow speed measurement, which are not efficient and lack integration.
Innovation Solution
A fill level measurement device that uses a single system to emit transmission signals in multiple directions, allowing for simultaneous or sequential determination of distance and flow speed by evaluating reflected signals, utilizing a signal generator module and antenna arrangement that can emit signals perpendicular and obliquely to the flow direction, and processing these signals to calculate distance and flow speed within a single measurement cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate measurement systems are used for distance detection and flow speed measurement, then each measurement function can be performed independently, but the device complexity increases and installation becomes more complex
Solution Approach 1:
The patent combines two separate measurement systems (pulsed radar for distance and Doppler evaluation for flow speed) into a single integrated measurement device that uses one antenna arrangement and one processor unit to perform both functions simultaneously, thereby reducing device complexity while maintaining measurement independence
Solution Approach 2:
The measurement device is designed with multi-functionality to perform both distance measurement and flow speed measurement using a single system, where the antenna arrangement can emit transmission signals in multiple directions and the processor unit evaluates different signal components for different measurement purposes
2Device complexity
If a single measurement system is used for both distance and flow speed measurement, then device complexity is reduced, but the measurement precision may be compromised
Solution Approach 1:
The single measurement system is segmented into specialized functional components: the antenna arrangement is configured to emit signals in specific directions (perpendicular and oblique to flow direction), and the processor unit segments the evaluation process to separately analyze distance information and flow speed information from the reflected signals, ensuring each measurement maintains high precision
Solution Approach 2:
Different parts of the measurement system are optimized for specific measurement functions: the antenna arrangement has directional radiation characteristics tailored for both distance and flow measurement, and the processor unit applies different evaluation algorithms to different signal components, ensuring local optimization for each measurement type
3Productivity
If transmission signals are emitted in multiple directions simultaneously, then both distance and flow speed can be measured in a single measurement cycle, but the use of energy increases
Solution Approach 1:
The measurement system uses continuous wave transmission signals that are emitted continuously in multiple directions, allowing simultaneous measurement of distance and flow speed in a single continuous measurement cycle, thereby improving productivity while managing energy consumption through efficient signal utilization
