[0094] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described below by way of example do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus consistent with some aspects of this disclosure as detailed in the appended claims.

[0095] To address the aforementioned technical problems, this disclosure provides a testing method, apparatus, system, and storage medium suitable for testing shavers, such as electric or manual shavers, hereinafter referred to as the shaver under test.

[0096] The tested razors in the examples of this disclosure include a razor assembly comprising at least one razor blade and a foil. When the razor rotates, the hairs entering the foil are cut by the razor blade, achieving the effect of shaving. In practical applications, considering the varying sharpness of the razor assemblies in different tested razors, the shaving effect will also differ. Therefore, it is necessary to test the sharpness of the razor assemblies of the tested razors. In subsequent embodiments, the cutting pull index is used to characterize the sharpness of the razor assemblies of the tested razors; and, the smaller the cutting pull index, the sharper the razor assemblies of the tested razors; conversely, the larger the cutting pull index, the less sharp the razor assemblies of the tested razors.

[0097] In the examples disclosed herein, hair, beard, artificial hair, or nylon filaments are used as test subjects to test the razors for ease of testing.

[0098] The testing method provided in this disclosure, with an existing preset test model, allows testers to detect the component parameters of the shaver's razor assembly and / or the object parameters of the shaver under test. Then, using the preset test model, the cutting pull force index of different shavers under test is obtained. The calculated cutting pull force index alone is sufficient to objectively evaluate the shaver under test, improving testing efficiency and making it suitable for early-stage development and later product selection. Furthermore, the calculated cutting pull force index can be compared with the actual measured value to verify whether the test passed, thus improving testing accuracy.

[0099] In one embodiment, see Figure 1 The aforementioned test system 10 includes: an input device 12, a weighing sensor 13, and a processor 11; the processor 11 is electrically connected to the input device 12 and the weighing sensor 13 respectively; the weighing sensor 13 is used to fix the object being tested B.

[0100] Input device 12 is used to acquire parameter data input by the user and send it to processor 11;

[0101] Weighing sensor 13 is used to detect the cutting tension generated when the object B is cut and send it to processor 11;

[0102] The processor 11 is used to obtain the component parameters of the razor assembly inside the tested shaver A and the object parameters of the tested object B based on the parameter data; wherein, the component parameters are used to characterize the influence of the structure of the razor assembly on the cutting pull capability of the tested shaver A; the object parameters are used to characterize the influence of the structure of the tested object B on the cutting pull capability of the tested shaver A.

[0103] The processor 11 is also used to determine a preset test model based on the cutting pull force, the component parameters of the shaving assembly in the tested shaver A, and the object parameters of the tested object B. The preset test model is used to determine the cutting pull force index of the tested shaver A. The cutting pull force index is the cutting pull force generated when the tested shaver A cuts the tested object B, and the larger the cutting pull force index, the worse the performance of the shaving assembly.

[0104] It should be noted that the above parameter data may include at least one of the following: the slot width K of the foil inside the razor assembly of the tested razor A, the thickness H of the foil, the width W of the blade inside the razor assembly, the shear angle change Delta A of the razor assembly, the depth S of the tested object B inside the razor assembly, the diameter D of the tested object B, the elastic modulus E of the tested object B, and the length L of the tested object B outside the razor assembly. These parameters can be selected according to the specific scenario, and the corresponding solutions fall within the protection scope of this disclosure.

[0105] In one example, the processor 11 can be a microcontroller, DSP chip, ARM chip, FPGA chip, etc., or a host computer can be used as the processor 11. The choice can be made according to the specific scenario, and the corresponding solution falls within the protection scope of this disclosure.

[0106] In one example, the input device 12 may include a keyboard, a touch sensor, or a peripheral terminal connected through an input interface, etc., which can be configured according to the specific scenario, and the corresponding scheme falls within the protection scope of this disclosure.

[0107] In one example, the load cell 13 can be implemented using a pressure sensor, a piezoelectric sensor, or a photoelectric sensor. For instance, when the load cell 13 uses a pressure sensor, the object being measured, B, is stretched, applying pressure to the pressure sensor, which can be detected as the cutting force. Alternatively, when the load cell 13 uses a photoelectric sensor, the stretching of the object being measured, B, causes an angular shift in the light, which can then be used to calculate the cutting force. It is understood that if parameters such as the tensile force, deformation, or deformation of the object being measured, B, can be detected when it is stretched, then the corresponding sensor used as the load cell 13 falls within the protection scope of this disclosure.

[0108] In one example, see [link to example]. Figure 1 The above-mentioned testing system also includes a planar displacement device 14 and a Z-axis displacement device 15; the processor 11 is electrically connected to the planar displacement device 14 and the Z-axis displacement device 15 respectively; the planar displacement device 14 is used to movably fix the shaver A under test; the Z-axis displacement device 15 is used to fix the weighing sensor 13;

[0109] The processor 11 is used to obtain the relative distance between the shaver A under test and the object B under test, and to generate a drive signal based on the relative distance and send it to the planar displacement device 14 and / or the Z-axis displacement device 15.

[0110] Planar displacement device 14 is used to move the tested shaver A in the X-axis direction and / or Y-axis direction when a drive signal is received;

[0111] Z-axis displacement device 15 is used to move the measured object B in the Z-axis direction when a drive signal is received.

[0112] In this example, the tested shaver A is moved in the X-axis and / or Y-axis directions by the planar displacement device 14, and / or the tested object B is moved in the Z-axis direction by the Z-axis displacement device 15. This allows the tested object B to align with and press against the blade of the tested shaver A. At this time, the relative distance between the tested object B and the blade of the tested shaver A ranges from -7.5mm to 7.5mm, simulating usage scenarios such as shaving beards, which helps improve the accuracy of subsequent test results.

[0113] In one example, see [link to example]. Figure 1 The aforementioned testing system further includes a clamping device 16; the clamping device 16 is fixed to the load cell 13; the clamping device 16 is used to clamp the object under test B. For example, the clamping device 16 may include a perforation and a fixing component; the perforation may be formed by the mating of two recesses of the fixing component, and then the movable part of the fixing component is fixed by screws or clips. The object under test can be placed inside the perforation and fixed by the fixing component. Those skilled in the art can configure the clamping device 16 according to the specific scenario. When it can be fixed to the load cell 13 and the object under test B is fixed, the corresponding solution falls within the protection scope of this disclosure.

[0114] See one example. Figure 2The aforementioned testing system also includes an image acquisition device 17. The image acquisition device 17 is electrically connected to the processor 11; the preview area (FOV) of the image acquisition device 17 covers a portion or all of the area where the clamping device 16 and the planar displacement device 14 are close together; the image acquisition device 17 is used to acquire the relative distance between the shaver under test and the object under test, and sends it to the processor 11; the processor 11 is used to generate a drive signal based on the relative distance and send it to the planar displacement device 14 and / or the Z-axis displacement device 15, the drive signal being used to drive the planar displacement device 14 and / or the Z-axis displacement device 15 to align the shaver under test A and the object under test B.

[0115] It is understood that the image acquisition device 17 mentioned above can be implemented using a planar camera, 3D camera, infrared imager or radar, etc. If the distance between the shaver A being tested and the object B being tested can be detected, the corresponding solution falls within the protection scope of this disclosure.

[0116] In one example, using a planar camera, an image can be captured and the foil of the shaver A under test can be identified in the image to obtain the edge of the foil closest to the object under test; and the edge of the object under test closest to the foil, or the edge of a specified area in the clamping device 16 closest to the foil, can also be identified. Once the foil and the object under test, or the foil and the specified area of ​​the clamping device, are determined, the relative distance between the shaver A under test and the object B under test can be directly obtained.

[0117] In another example, markers are set on the shaver A and the object B under test, and the image acquisition device 17 can move in the X-axis direction. The image acquisition device can take a first image of the shaver A under test at a first position and a second image of the shaver B under test at a second position. Then, the position of the marker on the shaver A under test is identified in the first image, and the position of the marker on the object B under test is identified in the second image. With the first position, the second position, and the positions of the two markers known, the relative distance between the shaver A and the object B under test can be calculated.

[0118] It should be noted that the above identification process can be implemented using a pre-trained neural network model, such as a convolutional neural network. If the tested shaver A, the tested object B, and the clamping device 16 can be identified, the corresponding neural network model falls within the protection scope of this disclosure.

[0119] In one example, the test system also includes a display; see further. Figure 2The display 18 is electrically connected to the processor 11. The processor 11 is also used to send and display at least one of the following: cutting tension, component parameters of the razor assembly inside the razor under test, object parameters of the object under test, and a preset test model. Furthermore, it can display intermediate data (such as weight data) or final results obtained during subsequent execution of the test method. Different data can be displayed depending on the specific scenario, and the corresponding scheme falls within the protection scope of this disclosure.

[0120] Based on the above Figure 1 and Figure 2 The test system shown in this disclosure also provides a test method, see [link to relevant documentation]. Figure 3 This includes steps 31 to 33.

[0121] In step 31, the cutting pull force generated when the razor under test cuts the object under test is obtained.

[0122] In this step, the processor 11 can acquire the cutting pull force generated when the shaver under test cuts the test object, see [link / reference]. Figure 4 This includes steps 41 to 43.

[0123] In step 41, the processor 11 can obtain the relative distance between the shaver under test and the object under test.

[0124] In this step, the processor 11 obtains the relative distance between the shaver under test and the object under test, which has already been described in the scheme describing the image acquisition device 17. For details, please refer to the above embodiment, and it will not be repeated here.

[0125] In step 42, when the relative distance is less than or equal to a preset distance threshold, the processor 11 controls the shaver under test to cut the object under test.

[0126] In this step, the processor 11 can compare the aforementioned relative distance with a preset distance threshold. This preset distance threshold can be set according to the specific scenario; in one example, the value range of the preset distance threshold can be [0, 10] mm.

[0127] When the relative distance is greater than the preset distance threshold, the processor 11 can determine that the shaver under test is far from the object under test. At this time, the processor 11 can generate a control signal and send it to the planar displacement device 14 and / or the Z-axis displacement device 15 to achieve the effect of adjusting the position of the shaver under test from the object under test.

[0128] When the relative distance is less than or equal to a preset distance threshold, the processor 11 can determine that the distance between the shaver under test and the object under test meets the requirements. At this time, the processor 11 controls the shaver under test to switch to the object under test. In one example, the processor 11 can be electrically connected to the shaver under test. For example, a controllable switch can be added to the power switch of the shaver under test. The control terminal of the controllable switch is electrically connected to the processor 11. The processor 11 can output a high-level signal to the controllable switch. After the controllable switch switches to the on state, the shaver under test starts working. In another example, the processor 11 can generate a reminder message and send it to the display for display. After the tester sees the reminder message, they can manually control the shaver under test to switch to the working state.

[0129] In step 43, the processor 11 can acquire the pressure value sent by the weighing sensor as the cutting pull force generated when the shaver under test cuts the object under test.

[0130] In this step, during the process of the shaver cutting the test object, the weighing sensor 13 detects the pressure value and sends it to the processor 11. The processor 11 can use the received pressure value as the cutting pull force generated when the shaver cuts the test object.

[0131] In step 32, the component parameters of the razor assembly inside the razor under test and the object parameters of the object under test are obtained; the component parameters are used to characterize the influence of the structure of the razor assembly on the cutting pull capability of the razor under test; the object parameters are used to characterize the influence of the structure of the object under test on the cutting pull capability of the razor under test.

[0132] In this step, the processor 11 can obtain the component parameters of the razor assembly inside the shaver under test, see [link / reference]. Figure 5 This includes steps 51 to 52.

[0133] In step 51, the processor 11 can obtain the slot width K, the thickness H of the foil, the width W of the blades, and the shearing angle change Delta A of the razor assembly of the tested shaver.

[0134] See one example. Figure 6 The slot width K in the inner foil of the tested shaver refers to the width between two adjacent foil ribs 61. The wider the slot width K, the more difficult it is for the shaver assembly to switch between tested objects.

[0135] See one example. Figure 7 The thickness H of the shaving mesh refers to the thickness when viewed from the vertical direction of the beard entering the mesh from the outside towards the cross-section of the mesh's ribs 61. The thinner the mesh thickness H, the easier it is to shave the object being tested; the thicker the mesh thickness H, the more difficult it is to shave the object being tested.

[0136] In one example, see [link to example]. Figure 6 The width W of the blade within the razor assembly refers to the length of the cutting edge on the blade used to cut the object being measured. It is understood that the blade 62 is set at a certain angle to the wire mesh 61 to facilitate capturing the object being measured.

[0137] In one example, the testing system may also include an angle measuring device. This device measures the shear angle difference, Delta A, of the razor assembly. See also Figure 8 The processor 11 can obtain the first shearing angle 81 between the blade 62 and the foil rib 61 in the razor assembly of the razor under test. The first shearing angle 81 refers to the angle between the razor and the reinforcing rib when the first corner a of the razor intersects with the reinforcing rib of the foil rib 61.

[0138] See Figure 9 The blade 62 includes a cutting edge 622 and a blade body 621. The intersection of the side containing the cutting edge 622 and the side containing the blade body 621 (6211, 6212) is called an angle (a, b). Among them, the angle formed by the side of the blade body 621 closer to the center position O of the razor assembly 621 and the cutting edge 622 is the first angle a, and the angle formed by the side farther from the center position O and the cutting edge 622 is the second angle b.

[0139] Similarly, the processor 11 can obtain the second shearing angle 82 between the blade 62 and the foil rib 61 in the razor assembly of the tested razor. The second shearing angle 82 refers to the angle between the razor and the reinforcing rib when the second corner b of the razor intersects with the reinforcing rib of the foil rib 61. It is understandable that... Figure 10 The first shear angle 81 is greater than the second shear angle 82. Then, the processor 11 can obtain the shear angle difference ΔA (or Delta A) between the first shear angle 81 and the second shear angle 82. The larger the shear angle difference, the sharper the blade 62 is, and the easier it is to cut the object being measured.

[0140] The first shear angle 81 is the largest to facilitate capturing the beard hairs; the second shear angle 82 has the largest shearing force to facilitate cutting the beard hairs. The component parameters in this example include the shear angle difference, which takes into account both the shear angle and shearing force—two objective factors. This allows for consideration of the impact of these two factors on the sharpness of the razor component, improving testing and design efficiency.

[0141] In one example, processor 11 may be electrically connected to input device 12 and acquire the aforementioned parameter data input by the user through input device 12.

[0142] In step 52, the processor 11 can determine the component parameters based on at least one of the slot width (K) of the foil, the thickness (H) of the foil, the width (W) of the blades in the razor assembly, and the shear angle variation (Delta A) of the razor assembly.

[0143] In this step, the processor 11 can obtain the first product of the slot width K, the blade width W inside the razor assembly, and the shear angle change Delta A of the razor assembly; then, the processor 11 can obtain the thickness H of the blade foil and the first quotient of the first product as the component parameter N.

[0144] In one example, the expression for the component parameter N is shown in equation (1).

[0145]

[0146] It should be noted that the above embodiments describe a scheme for determining component parameters using four parameters. In some possible examples, at least one of the following can be used to determine component parameters: the slot width K, the blade thickness H, the blade width W inside the razor assembly, and the shear angle change Delta A of the razor assembly. For example, the slot width K and the blade thickness H can determine component parameter N = H / K; similarly, the blade thickness H and the blade width W inside the razor assembly can determine component parameter N = H / W. The expression for component parameters can be set according to the specific scheme, and the corresponding scheme falls within the protection scope of this disclosure.

[0147] In this step, the processor 11 can obtain the object parameters of the object under test, see [link to relevant documentation]. Figure 10 This includes steps 101 to 102.

[0148] In step 101, the processor 11 can obtain the depth S of the object under test inside the razor assembly, the diameter D of the object under test, the elastic modulus E of the object under test, and the length L of the object under test outside the razor assembly.

[0149] See one example. Figure 11 The object being tested, B, enters the interior of the razor assembly through the perforations. At this point, the object is located at a depth S within the razor assembly. Furthermore, the greater the depth S of the object within the razor assembly, the less likely it is to be cut off.

[0150] In one example, see [link to example]. Figure 11 The test object B enters the interior of the razor foil through the holes in the foil. At this point, the length L of the test object outside the razor assembly is [length L]. Furthermore, the greater the length L of the test object outside the razor assembly, the less likely it is to be cut off.

[0151] In one example, the testing system may also include an elastic modulus measuring device for measuring the elastic modulus of the object under test. Furthermore, the smaller the elastic modulus of the object under test, the easier it is to cut it off.

[0152] In this example, the processor 11 can obtain the depth S of the object under test inside the razor assembly, the diameter D of the object under test, the elastic modulus E of the object under test, and the length L of the object under test outside the razor assembly, which are input by the user through the input device.

[0153] In step 102, the processor 11 can determine the object parameters based on at least one of the depth S of the object being measured inside the razor assembly, the diameter D of the object being measured, the elastic modulus E of the object being measured, and the length L of the object being measured outside the razor assembly.

[0154] In one example, processor 11 can obtain a second product of the depth S of the object under test inside the razor assembly, the diameter D of the object under test, and the elastic modulus E of the object under test. Then, processor 11 can obtain a second quotient of the second product and the length L of the object under test outside the razor assembly as the object parameter M.

[0155] In one example, the expression for the object parameter M is shown in equation (2).

[0156]

[0157] It should be noted that the above embodiments describe a scheme for determining object parameters using four parameters. In some possible examples, at least one of the following can be used to determine object parameter M: the depth S inside the razor assembly, the diameter D of the object being measured, the elastic modulus E of the object being measured, and the length L of the object being measured outside the razor assembly. For example, the depth S inside the razor assembly and the length L of the object being measured outside the razor assembly can determine object parameter M = S / L; or, the diameter D of the object being measured and the length L of the object being measured outside the razor assembly can determine object parameter M = D / L. The expression for the object parameter can be set according to the specific scheme, and the corresponding scheme falls within the protection scope of this disclosure.

[0158] In step 33, a preset test model is determined based on the cutting pull force, the component parameters of the shaving assembly inside the shaver under test, and the object parameters of the object under test. The preset test model is used to determine the cutting pull force index of the shaver under test. The cutting pull force index is the cutting pull force generated when the shaver under test cuts the object under test, and the larger the index, the worse the performance of the shaving assembly.

[0159] In this step, the cutting pull force, the component parameters of the razor assembly inside the tested razor, and the object parameters are used as the current test parameters, and at least one set of historical test parameters are acquired. Then, the processor 11 performs fitting processing on the current test parameters and at least one set of historical test parameters to obtain at least one candidate test model; the candidate test model may include an exponential model, a linear model, or a nonlinear model, etc. Then, the processor 11 can perform verification processing on at least one candidate test model, for example, acquiring the component verification parameters of the razor and the object verification parameters of the verification object; then, the processor 11 can determine the calculated value of the cutting pull force exponent output by each candidate test model in at least one candidate test model based on the component verification parameters and the object verification parameters; subsequently, the processor 11 can obtain the actual value of the cutting pull force generated when the razor cuts the verification object; when the error between the actual value and the calculated value is less than or equal to a preset error threshold, the processor 11 can determine the candidate test model as the preset test model.

[0160] In one example, the preset test model is implemented using an exponential model, as shown in equation (3).

[0161]

[0162] In equation (3), Y represents the cutting tensile force index, and α and β are the weight indices of component parameters and object parameters, respectively.

[0163] Understandably, once the preset test model is determined, the weighting indices of the component parameters and object parameters can be determined. After the shaver under test is changed, it is only necessary to obtain the component parameters and object parameters of the shaver under test and input them into the aforementioned preset test model to calculate the cutting tensile force index.

[0164] Thus, this embodiment can obtain a preset test model through the testing system, and use the preset test model to obtain the cutting pull index of different tested shavers, so as to achieve the effect of objectively evaluating the tested shavers, improve testing efficiency, and is suitable for early development and later product selection.
