The present disclosure relates to a device for cosmetic applications. More specifically, the present disclosure relates to a device for measuring combability of fibers comprising a replaceable comb, a handle, and sensors as well as printed circuit board (PCB) in a suitable housing. Also, the present disclosure relates to a device with load sensor for measuring the combing force that provides for evaluating the conditioning of the hair / fibre and that can be used with as well as without assistance. As a hand-held system, the device is suitable for self-assessment. The present disclosure is to provide a device that is simple, cost-effective, with high sensitivity and efficient so that individuals can easily check their hair conditioning with a light-weight device. Further, the present disclosure provides combs that can be replaced and can easily be modified, accessed and connected to a smart device.

BACKGROUND:
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided in the present invention is prior art or directly relevant to the presently claimed invention. All documents cited herein are hereby incorporated by reference in their entirety, unless otherwise excluded or otherwise limited, including any cross-referenced or related patent or application, as well as any patent application or patent to which this application claims priority or benefit thereof.

Any publication cited herein is not intended to be taken as prior art with regard to any invention disclosed or claimed herein, nor does it teach, suggest, or disclose any such invention on its own or in any combination with other reference or references. Furthermore, the definition or meaning given to a term in this document will take precedence over definitions or meanings of the same term in documents included by reference to the extent that they conflict.

Further, for the purpose of discussion, human hair is taken as a representative of fibre and it is understood that the purpose as well as usefulness of the inventive device is applicable to all types of fibre in bulk.
The daily morning routine for individuals with long hair often involves contending with hair entanglement resulting from fiber-to-fiber friction/adhesion. The present application addresses this challenge by focusing on measuring the resistance encountered by a comb as it traverses through a bundle of hair. Traditionally, this resistance is quantified through force measurement, with the option to also gauge the work done during the combing process along the length of the hair.

Evaluating the condition of hair and the effectiveness of cosmetic treatments is crucial for determining the efficacy of interventions aimed at preventing or repairing damage to keratinaceous fiber. Various methods and comb sensors have been explored in attempts to assess hair condition. One common approach involves measuring the combing resistance of fibers, particularly focusing on factors like friction and detangling. Typically, damaged hair exhibits heightened combing resistance in comparison to healthier strands.

The present disclosure is related to evaluating bulk property of fibres such as hair- more particularly measuring a primary benefit delivered by hair care products. It is already reported in literature that the property of a single fiber varies from root to tip and by age as well. So, studying the individual hair fibers does not help to understand the behavior of the hair in bulk. The disclosed device will help to assess the extent or quality of conditioning of the bulk hair and thus would be able to help choose suitable hair care products by the individuals – both consumers and service providers. The proposed device is compact and light weight and is suitable for operation by the individuals.

These below examples illustrate the diverse range of prior art related to portable devices that are used to assess various bulk properties of hair.

Given the recent surge in technological advancements, smart devices have garnered increased attention, and present disclosure stands poised to revolutionize the measurement of consumer experience at site – be it home, beauty service centers, manufacturing centers, quality control / scientific laboratory etc. Against this backdrop, a prevailing trend in the personal care industry leans towards customizing hair and skin care products for individuals, departing from the one-size-fits-all approach. Understanding the condition of one's hair – more particularly tangling and conditioning - serves as the initial step in recommending/identifying suitable products to either improve or maintain its health. Further, such a device can be used to assess the effect of any product or treatment on tangling as well as conditioning. The inventive combing device is designed to assess the state of tangling and conditioning of hair/fibre in situ.

WO2019018151 discusses the use of bend sensors attached to a few comb bristles to detect and measure the bending or curvature of objects. However, this sensor design can be complex because each bristle needs to be equipped with a sensor. The comb sensor may further comprise an additional sensor. Such additional sensors are, for example, those selected from the group consisting of moisture sensor, temperature sensor, sebum sensor, oil sensor, and any combinations thereof. The present disclosure, in contrast, proposes a simpler and more economical design, utilizing a single sensor with high sensitivity. The present design is suitable for in situ measurement of tangling and conditioning of fibers in bulk. The comb can be easily changed to adapt to different needs. By using a single load sensor instead of multiple sensors in each bristle, the design also offers the advantage of easier repair and maintenance.

US20030226397 discloses a sensor-based portable device engineered to assess the moisture content of hair, providing valuable insights into its hydration levels. This prior art does not give any information on tangling and conditioning. In contrast, the present invention provides design of a simple, economical and highly sensitive device that is suitable for in situ measurement of tangling and conditioning of fibres in bulk.

US4167869 discloses an apparatus for measuring incremental grooming force consisting of a comb or brush having one or more thin film strain gauges. These gauges are attached to the shaft of the comb and measure the bending moment, or the amount of bending, in the shaft as it experiences force during use wherein the change in resistance is electrically measured to provide an indication of incremental grooming force. This setup allows for the measurement of the force exerted when combing hair. The present device differs in that the comb is attached directly to a load cell. The present design simplifies the measurement process by directly measuring the force applied to the comb, rather than inferring it through the bending of the shaft. This approach enhances accuracy and simplifies the construction and maintenance of the device.

US11612236B2 [WO2021237236] utilizes a proximity sensor, such as a light-dependent resistor, to determine whether the grooming device is near the hair. Based on this sensor, data from other sensors is stored and analyzed. The device's effectiveness heavily depends on the proximity sensor, with potential for errors arising from lighting conditions that may affect the sensor's accuracy. Additionally, the integration of proximity sensors and real-time data filtering mechanisms necessitates advanced hardware, which increases the device's weight, cost, and complexity. Our present disclosure avoids the use of such a proximity-based, hardware-intensive filtering mechanism. In the present design, the control unit does not perform any filtering or processing; its sole function is to transmit raw data to a computer, allowing for greater flexibility in how the data is analyzed post-collection. The present device includes a distance calculation feature that tracks the distance traveled by the device over the hair sample. It also incorporates a gyroscope sensor that provides coordinate data, ensuring that readings are taken in a straight line. These features enhance the repeatability and accuracy of experiments. The disclosed device introduces a replaceable comb feature with split casing design, allowing for easy customization, maintenance, and versatility.

US3946606A uses mechanical components like a friction wheel, and a clutch mechanism to measure forces to untangle the hair. It converts physical resistance into rotational movements recorded by a counter. The present design discloses the use of electronic sensors for more precise and real-time measurements, simplifying the design and offering easier calibration and maintenance.

The present disclosure meets not only the current requirements but also addresses additional needs, effectively surpassing the shortcomings observed in prior art. The present disclosure is to provide a device that is simple, cost-effective, highly sensitive and efficient so that individuals can easily check their hair conditioning with a light-weight device. Further, the present disclosure provides combs that can are replaceable and can easily be accessed and connected to a smart device.
The present disclosure satisfies the existing needs, as well as others, and generally overcomes the deficiencies found in the prior art.

EXAMPLES:
Example 1: Performance Comparison With Desktop System: Conditioning Effect Of Cosmetic Products
In order that this disclosure is more fully understood, the following preparative and testing examples are set forth. However, it is to be understood that the foregoing examples are merely illustrative and are not to be taken as limitations upon the scope of the disclosure. Various changes and modifications to the disclosed embodiments will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the disclosure. Aspects of the present disclosure are further understood in light of the following examples, which should not be considered as limiting the scope of the present disclosure.

The present disclosure aims to measure the properties of hair during combing and compare the performance of the inventive device with benchtop instruments like the Dia-Stron Tensile Tester (MTT 175). While the inventive device is designed for use on actual volunteers' heads, the desktop tensile tester is not suitable for such applications. Therefore, hair swatches rather than human heads were utilized in the experiments. The performance of the devices was evaluated by treating commercially available hair care products. The studies were conducted using hair swatches consisting of natural, untreated Indian black hair.

The hair swatches were first washed with a 10% sodium lauryl ether sulfate (SLES) solution, followed by water wash and drying in ambient air. and measurements were taken as a baseline (pre-treatment). Following the SLES treatment, the swatches were divided into separate sets, with each set treated with a different commercially available hair care product, including shampoo, serum, or hair oil, to evaluate their individual effects on detangling and ease of combing.

• For the shampoo-treated set, the shampoo was applied and rinsed off, and the swatches were air-dried at room temperature before combing tests.
• For the serum-treated and oil-treated sets, the products were applied as leave-on treatments, and measurements were taken directly after 15 minutes.

Each set contained four swatches, and each swatch was combed 10 times using the inventive device (100) or the standard desktop device (607). The average values of the recorded measurements were calculated and analyzed. The force data during combing was recorded using both the inventive device (100) and the standard desktop device (607) to enable a direct performance comparison.

Table 1: Experiment Summary and Treatment Results
Description Treatment (Post wash) Results (% change ± STD)
Inventive Device Standard Desktop Device
Detangling Ease of combing Detangling Ease of combing
Set#1: Natural Black hair Commercial Shampoo -42.84 ± 7.8 -43.40 ± 14.1 -25.60 ± 9.1 -21.20 ± 8.4
Set#2: Natural Black hair Commercial Hair Serum -93.84 ± 2.1 -76.90 ± 4.5 -92.20 ± 3.4 -66.50 ± 3.4
Set#3: Natural Black hair Commercial Hair oil -95.51 ± 0.5 -91.39 ± 2.0 -85.00 ± 6.4 -56 02 ± 7.4
Note: A negative value indicates that the measurement value has decreased compared to the pre-wash measurement, std refers standard deviation.

Figure 5 depicts a typical output automatically displayed for a single combing operation after releasing the momentary switch (107). The x-axis (503) denotes the position of the comb in centimeters as it moves through the hair, while the y-axis (504) represents the force sensed during the combing process. The graph demonstrates a constant horizontal force followed by a sharp peak at the end. One embodiment of the device measures the highest level of resistance encountered by the comb as it moves through the hair, represented as the Peak Force (501).

Another embodiment measures the effort required to comb the hair, expressed as Workdone (502), which is the ease of combing.

Figure 6 illustrates the detangling and ease of combing efficacies, expressed as percentages, for different hair treatment conditions. These values are calculated from the force data collected during combing with the inventive device (100) compared to a standard desktop device (607). Figure 6A represents three treatment conditions for black hair: rinse-off shampoo (603), leave-on oil (604), and leave-on serum (605). Negative values indicate that the hair treatment reduces tangling, leading to a reduction in combing force.

Figure 6B depicts the ease of combing efficacy, expressed as a percentage, for the same hair treatment conditions as in Figure 6A, comparing the inventive device (100) with the standard desktop device (607). Furthermore, when conducting independent t-tests between each set of measurements, no significant difference (p-value > 0.05) was observed between the devices. This confirms their similar performance. The inventive device demonstrates performance comparable to the standard desktop device across all treatment conditions.

An advantage of the inventive device is that the comb is directly connected to the load cell, enabling real-time measurement of the force applied during combing. This design eliminates the need to nullify the weight of the hair swatch, as is required in standard desktop devices. The standard device uses a more complex method, where the load cell is connected to the hair swatch and the device software compensates for the swatch weight during combing. The direct connection in the inventive device results in more accurate and sensitive measurements, leading to higher efficacy in assessing ease of combing and detangling.

The device is designed for practical and portable use, making it suitable for analyzing hair properties and evaluating the impact of hair care treatments. The device achieves a compact and cohesive design, optimizing space and assembly efficiency. The integration of three different sensors also enhances data accuracy and analysis.

Although specific examples and descriptions of the present disclosure have been provided, those with expertise in the field would recognize that several other adjustments and alterations can be made without deviating from the essence and extent of the innovation. Therefore, all such alterations and modifications that fall under the purview of this disclosure are meant to be covered by the appended claims.
