Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound velocity sensors are not space-saving and typically located outside fluid lines, making them inconvenient for process monitoring and integration into fluid lines.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound velocity sensors are arranged outside fluid lines, then measurement reliability is improved, but space utilization deteriorates and integration into fluid lines becomes difficult
Solution Approach 1:
The patent combines the sound velocity sensor with the fluid line by integrating the measuring chamber directly into the fluid line structure. The sensor housing is merged with the fluid line, allowing the sensor to occupy the same space as the fluid flow path, thus achieving both compact space utilization and reliable in-line measurements without requiring separate external mounting space.
2Volume of moving object
If sound velocity sensors are arranged in fluid lines, then space-saving design is achieved, but structural complexity increases
Solution Approach 1:
The fluid line structure serves multiple functions: it acts as both the fluid transport conduit and the housing for the sound velocity sensor. The sensor housing is integrated into the fluid line, allowing the same structural element to perform both fluid containment and sensor mounting functions, thereby reducing overall structural complexity despite the in-line arrangement.
3Ease of operation
If measuring chamber is axially displaceable, then opening and closing of inlet/outlet openings is enabled, but device complexity increases
Solution Approach 1:
The measuring chamber is designed with axial displacement capability, transitioning from a static to a dynamic structure. This allows the inlet and outlet openings to be opened or closed by moving the measuring chamber axially relative to the sensor housing, enabling operational control without requiring separate valve mechanisms or complex opening/closing systems.
