Description:SYSTEM FOR DETERMINING QUALITY PARAMETERS OF A LIQUID SAMPLE
Field of the Invention
[0001] The present disclosure generally relates to systems for analyzing liquid samples. Further, the present disclosure particularly relates to a system for determining quality parameters of a liquid sample using optical detection and machine learning techniques.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Various systems are known for determining the quality parameters of liquid samples in different applications, including medical, industrial, and environmental fields. Such systems typically rely on the interaction of light with the liquid sample to measure parameters like chemical composition, turbidity, and particle concentration. The most common approach involves passing light through the liquid sample and detecting the transmitted or scattered light to infer the quality parameters. These systems usually consist of a light source, a detection unit, and a processing mechanism for analyzing the detected signals. Despite their widespread use, known systems face several challenges in terms of precision, flexibility, and efficiency in determining specific parameters.
[0004] One well-known system employs single-wavelength light sources and basic photodetectors to assess liquid sample properties. While effective in specific applications, such systems are limited in their ability to capture a broad spectrum of quality parameters, particularly in complex liquid compositions. The single-wavelength approach often lacks the resolution needed to distinguish between different molecular or particulate structures within the sample. Furthermore, environmental interference, such as ambient light or vibrations, often degrades the accuracy of the measurements. As a result, users may face limitations when applying these systems to varied or dynamic conditions, which reduces their overall applicability across different industries.
[0005] Another commonly used system utilizes multi-wavelength light sources and spectrometric sensors to improve accuracy. Such systems are designed to detect a wider range of transmitted light wavelengths, allowing for more detailed analysis of the liquid sample’s molecular structure. However, this setup often requires highly sensitive equipment and calibration to ensure accurate results. The complexity of such systems makes them more expensive and prone to errors due to sensor misalignment or mechanical wear over time. Additionally, the processing units of such systems are generally less capable of handling large data sets and may struggle to efficiently analyze the wide range of light signals without introducing delays or inaccuracies in the determined quality parameters.
[0006] Other state-of-the-art systems may incorporate techniques such as fluorescence detection or scattering-based analysis to measure quality parameters of a liquid sample. These techniques involve additional components like optical filters or mirrors to modify the light path, which increases the complexity of the system. Such systems also tend to have a limited operational range and require frequent maintenance or recalibration, making them less reliable for long-term or high-volume applications. Moreover, these systems are generally less adaptable to different liquid compositions, reducing their overall flexibility and scope of application.
[0007] In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and techniques for determining quality parameters of a liquid sample.

The spring-loaded base provides a cushioning effect when the cuvette 104 is placed into the mounting structure, reducing the impact of any sudden movements and preventing damage to the cuvette 104 or the liquid sample. This shock absorption feature ensures that the cuvette 104 remains properly aligned with the light source array 106 and sensor assembly 108, even if slight forces are applied during insertion or removal. Additionally, the spring-loaded base stabilizes the cuvette 104 during the measurement process, preventing any vibrations or shifts that could affect the precision of the light transmission and detection. This is particularly useful in environments where the system 100 is subjected to mechanical vibrations or movements, ensuring that the cuvette 104 remains stable and the measurement process is not disrupted. The spring-loaded base also facilitates easy removal and replacement of the cuvette 104, allowing users to quickly and safely change samples without risking damage to the system components. By providing shock absorption and stabilization, the spring-loaded base enhances the overall durability and accuracy of the system 100 during liquid sample analysis.
[00054] In an embodiment, the light source array 106 of the system 100 is coupled to the chassis 102 by a swivel joint, allowing for rotational adjustment of the light source array 106 around a vertical axis.

The swivel joint allows the light source array 106 to be rotated to the desired angle and locked in place, ensuring stability during the measurement process. This flexibility in light direction enhances the system’s ability to accurately measure a wide range of liquid samples with varying refractive properties. The rotational adjustment is particularly useful when dealing with complex samples that require multiple light angles to capture the full range of optical data. The swivel joint also facilitates easy re-adjustment of the light source array 106 when switching between different sample types or measurement protocols. The ability to rotate the light source array 106 around the vertical axis improves the adaptability and precision of the system 100, ensuring that optimal light transmission is achieved for each liquid sample.
[00055] In an embodiment, the sensor assembly 108 is affixed to a height-adjustable mounting plate, which is interconnected with a screw-driven actuator located within the chassis 102 . The screw-driven actuator allows for precise vertical adjustments of the sensor assembly 108 relative to the cuvette 104, ensuring consistent detection of transmitted light across varying liquid sample depths. This height-adjustable feature is particularly beneficial when analyzing samples of different volumes or when the liquid level within the cuvette 104 may vary.

The counterweight-balanced arm enhances the overall stability and functionality of the system 100, ensuring reliable and accurate quality parameter determination for liquid samples.
[00057] In an embodiment, the cuvette 104, configured to receive the liquid sample, allows for optimal containment of the sample during analysis. The transparent design ensures that the emitted light from the light source array 106 can pass through the liquid sample without significant distortion. This configuration facilitates accurate detection by the sensor assembly 108, as the optical properties of the liquid sample, such as absorption, turbidity, or transmission, can be captured with minimal interference. The precise containment and positioning of the cuvette 104 within the chassis 102 enhance the reproducibility of measurements, reducing the potential for errors associated with sample misalignment or contamination.
[00058] In an embodiment, the light source array 106, positioned at a preset distance from the cuvette 104 and connected to the chassis 102 via an interlocking mount, provides structural stability and ensures optimal light transmission through the liquid sample. The preset distance is calibrated to minimize loss of light intensity and prevent overexposure of the liquid sample. The interlocking mount prevents vibrations from affecting the light beam’s direction, reducing noise in the measurements. This stable arrangement improves the accuracy and repeatability of the quality parameter determination, especially in environments subject to mechanical disturbances.
[00059] In an embodiment, the chassis 102 includes a sliding rail assembly that allows the cuvette 104 to be inserted and removed with minimal mechanical interference. The sliding rail assembly reduces friction, ensuring smooth movement and preventing damage to both the cuvette 104 and the surrounding components. This feature ensures that the cuvette 104 can be easily accessed for cleaning, maintenance, or replacement, without affecting the alignment of the light source array 106 or the sensor assembly 108. By maintaining consistent cuvette positioning during repeated measurements, this assembly improves accuracy and reduces user intervention time.
[00060] In an embodiment, the light source array 106 is mounted on an adjustable arm, which allows angular positioning relative to the cuvette 104. This adjustability enables the system 100 to direct the light beam at different angles, optimizing light penetration based on the refractive properties of the liquid sample. This flexibility improves light interaction with the sample, leading to enhanced detection of specific optical phenomena such as scattering or absorption. The adjustable arm ensures that the system 100 can accommodate a wide range of liquid samples with varying optical characteristics, enhancing the overall versatility and accuracy of the system.
[00061] In an embodiment, the chassis 102 includes a mounting structure with multiple mounting holes to secure the cuvette 104 in a vertical position during the measurement process. This secure vertical alignment ensures that the light emitted from the light source array 106 passes directly through the liquid sample without deviation, improving the consistency and accuracy of transmitted light detection by the sensor assembly 108. The mounting holes allow the system to accommodate different cuvette sizes or shapes, ensuring a stable and consistent measurement process across a variety of liquid samples.
[00062] In an embodiment, the cuvette 104 is supported by a spring-loaded base within the mounting structure, which provides shock absorption and stabilization during the insertion process. The spring-loaded base prevents the cuvette 104 from experiencing sudden movements or shocks that could misalign the sample or disrupt light transmission. This stabilization improves the accuracy of measurements by maintaining the precise positioning of the cuvette 104, ensuring consistent light interaction with the liquid sample during the entire measurement cycle. It also prevents potential damage to the cuvette 104, enhancing the system’s durability and operational longevity.
[00063] In an embodiment, the light source array 106 is coupled to the chassis 102 by a swivel joint, enabling rotational adjustment of the light source array 106 around a vertical axis. This rotational adjustment allows the system 100 to direct light at specific angles through the cuvette 104, optimizing light transmission for liquid samples with varying refractive indices. The swivel joint improves the flexibility of the system, allowing precise light targeting to enhance the accuracy of the optical measurements, particularly in cases where the liquid sample’s properties require specific light angles for accurate detection.
[00064] In an embodiment, the sensor assembly 108 is affixed to a height-adjustable mounting plate, which is interconnected with a screw-driven actuator located within the chassis 102. The screw-driven actuator allows for precise vertical adjustments of the sensor assembly 108 relative to the cuvette 104. This vertical adjustability ensures that the sensor assembly 108 remains properly aligned with the cuvette 104, regardless of the liquid sample’s depth or volume. The ability to fine-tune the sensor assembly’s position enhances the system’s capacity to detect light transmitted through liquid samples of varying depths, improving the consistency and precision of the quality parameter analysis.
[00065] In an embodiment, the sensor assembly 108 is mounted on a counterweight-balanced arm, which is pivotally connected to the chassis 102. The counterweight system automatically adjusts the position of the sensor assembly 108 relative to the cuvette 104, compensating for minor shifts in the placement of the cuvette 104. This automatic adjustment ensures that the light transmitted through the liquid sample is consistently detected, even if the cuvette 104 is slightly misaligned. The counterweight system enhances the stability of the sensor assembly 108 during the measurement process, improving the overall accuracy and reliability of the optical data collected by the system 100.
