Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current measurement systems are used, then liquid volume measurement can be performed, but the measurement is inefficient and unreliable
Solution Approach 1:
The patent replaces mechanical measurement systems with an optical system using laser beams and sensors. The laser beam passes through the vessel wall and liquid interface, and sensors detect the position of the liquid level by measuring light transmission or refraction, eliminating the need for mechanical contact with the liquid
Solution Approach 2:
The patent introduces an optical intermediary (laser beam) that interacts with the liquid level to provide measurement information. The laser beam serves as a mediator between the measurement system and the liquid, allowing non-contact detection of liquid level and volume
2Extent of automation
If automated systems are implemented, then processing efficiency can be improved, but implementation becomes exceptionally challenging
Solution Approach 1:
The measurement system is designed to automatically detect liquid levels and calculate volumes without requiring manual intervention. The laser apparatus continuously emits beams and the sensor array automatically processes the optical signals to determine liquid parameters, enabling self-operating automated workflows
Solution Approach 2:
The system divides the measurement task into discrete components: laser beam emission, optical signal transmission through vessel and liquid, sensor detection at multiple points, and computational volume calculation. This segmentation allows each component to be independently optimized and controlled for automation
3Measurement precision
If precise liquid volume measurement is achieved, then reagent addition can be precise, but measurement reliability must be improved
Solution Approach 1:
The system uses multiple laser beams at different heights rather than a single measurement point. This provides redundant measurements and allows verification of results, improving reliability while maintaining precision through statistical or comparative analysis of multiple data points
Solution Approach 2:
The sensor array provides real-time feedback on liquid level positions by detecting optical signal changes. This feedback mechanism allows the system to continuously monitor and adjust measurements, ensuring both precision and reliability through iterative verification

Data Source
AI summary
Systems and methods are disclosed for measuring the volume of liquid contained in a vessel. A sensor array comprising a plurality of sensors and a laser apparatus comprising one or more lasers can be positioned relative to each other such that lasers beams emitted from the laser(s) can be received by the sensor array. The vessel can be positioned such that each laser beam intersects the vessel at a certain predetermined height. A liquid level's height may be determined by the volume of liquid in the vessel. A refraction of a laser beam may be influenced by the presence or absence of liquid at that predetermined height, which could be the result of the liquid level's height being above or below that predetermined height. Readings from the sensor array may determine where refraction occurs, allowing ranges or values of the volume of liquid in the vessel to be extrapolated.
