[0046] The solution provided by the present invention is described below in conjunction with the accompanying drawings.

[0047] Figure 1 FIG. 1 is a flow chart showing a design method of a bilateral cervical pillow according to an embodiment. It is understood that the method can be executed by any device, equipment, platform, or equipment cluster with computing and processing capabilities. Figure 1 As shown, the method includes:

[0048] Step 100: photograph the upper body of the target user to obtain a side view photo and a front view photo; wherein the upper body includes the head, neck and back;

[0049] Step 102: Based on the lateral photograph and the frontal photograph, a bilateral cervical pillow having both supine and lateral positions is designed.

[0050] In this embodiment, the upper body of the target user is first photographed to obtain a lateral photo and an orthodontic photo, and then a bilateral cervical pillow with both supine and lateral positions can be designed based on the lateral photo and the orthodontic photo, and the bilateral cervical pillow can simultaneously meet the user's supine sleeping needs and lateral sleeping needs. Therefore, the above technical solution can improve the personalized matching degree of the cervical pillow.

[0051] In some implementations, taking photos may be done with a mobile phone or other camera equipment, which is not specifically limited here. Figure 3 As shown, by taking side and front photos of the upper body of the target user, a side photo and a frontal photo can be obtained.

[0052] As a preferred embodiment, the step of "designing a bilateral cervical pillow having both supine and lateral positions based on the lateral and frontal photographs" may specifically include:

[0053] The curvature inflection points of the lateral and frontal photographs were identified to obtain the supine arc and lateral arc, respectively.

[0054] Based on the supine position arc and the lateral position arc, a bilateral cervical pillow with both supine and lateral positions is designed.

[0055] In this embodiment, by identifying the curvature inflection point of the lateral photo and the frontal photo, the supine arc and the lateral arc can be obtained respectively, so that a bilateral cervical pillow with both supine and lateral positions can be designed.

[0056] It should be noted that the recognition of the curvature inflection point belongs to the technology of contour recognition, and the recognition technology of the curvature inflection point is not described in detail here, as it is well known to those skilled in the art.

[0057] by Figure 3 For example, the curvature inflection point is Figure 3 The green dot in the middle, but the supine arc and the lateral arc only select the arc interval of some green dots. For example, the green dot on the top of the head is also a curvature inflection point, but it is not a reference point for the supine arc and the lateral arc.

[0058] In some embodiments, the arc can be enhanced based on the target user's pain. A lying experiment can be set for the target user. The lying experiment is an experiment to detect whether the target user has pain through a pre-set cervical pillow. If the target user has pain, but in order to maintain the status quo as much as possible to get better treatment, the arc of the supine position and the lateral position can be enhanced, that is, the convex part is more convex.

[0059] As a preferred embodiment, the step of "designing a bilateral cervical pillow having both supine and lateral positions based on the supine position arc and the lateral position arc" may specifically include:

[0060] Obtain the back thickness and shoulder width of the target user;

[0061] Based on the curvature inflection points of the lateral and frontal photographs, the first horizontal reference line of the lateral photograph (i.e. Figure 3 horizontal line of the supine shape) and the second horizontal reference line of the anteroposterior photo (i.e. Figure 3 The first horizontal reference line is the line connecting the curvature inflection point at the end of the head and the curvature inflection point at the top of the back, and the second horizontal reference line is the line connecting the acromion points on both sides;

[0062] The back thickness dimension is input into the supine arc and connected with the first horizontal reference line to obtain the supine cross-sectional profile;

[0063] Input the shoulder width into the side-lying arc and connect it with the second horizontal reference line and the preset n-th order curve (that is, Figure 3 The gap of the side-lying shape shown is closed with an n-order curve) to obtain the side-lying cross-sectional profile; wherein n≥3;

[0064] Based on the cross-sectional profile of the supine position and the cross-sectional profile of the lateral position, a bilateral cervical pillow with both the supine position and the lateral position is designed.

[0065] In this embodiment, by inputting the actual size of the target user, the actual supine cross-sectional contour and lateral cross-sectional contour of the cervical pillow can be obtained on the basis of determining the closed curve composed of various arcs, horizontal reference lines, etc., so that a bilateral cervical pillow with both supine and lateral positions can be designed.

[0066] It should be noted that the back thickness is Figure 3 The height from the top of the arc of the supine shape to the horizontal line is the shoulder width. Figure 3 The horizontal distance between the left and right endpoints of the arc of the side-lying shape shown.

[0067] In addition, based on the supine position arc and the lateral position arc, the supine position cross-sectional profile and the lateral position cross-sectional profile can also be obtained by inputting a proportional coefficient of the actual size, which is not specifically limited here.

[0068] As a preferred embodiment, the step of "designing a bilateral cervical pillow having both supine and lateral positions based on the supine cross-sectional profile and the lateral cross-sectional profile" may specifically include:

[0069] The supine cross-sectional contour is stretched by a preset length in a direction perpendicular to the supine cross-sectional contour to obtain a supine model;

[0070] The lateral position cross-sectional profile is stretched by a preset length in a direction perpendicular to the lateral position cross-sectional profile to obtain a lateral position model;

[0071] The supine position model and the lateral position model are overlapped to design a bilateral cervical pillow with both supine and lateral positions; wherein the preset length is evenly divided into three sections, the first and third sections are the lateral position models, and the second section is the supine position model.

[0072] In this embodiment, after obtaining the cross-sectional profile of the supine position and the cross-sectional profile of the lateral position, a supine position model and a lateral position model can be obtained by performing a stretching process of a preset length; then the two models are overlapped to obtain a bilateral model (i.e. Figure 3 The model corresponding to the "bilateral" shown in the figure) can thus design a bilateral cervical pillow with both supine and lateral positions.

[0073] See also Figure 4 As a preferred embodiment, the side-lying model of the first section, the supine model of the second section and the side-lying model of the third section are connected in sequence by arc surfaces, the edges of the side-lying model of the first section and the side-lying model of the third section close to the supine model of the second section are provided with arc-shaped protrusions, the top of the head of the supine model of the second section is a hollow structure, the side-lying model of the first section and the side-lying model of the third section have the same height, and their heights are higher than the height of the supine model of the second section.

[0074] In this embodiment, the arc surface connection can achieve a smooth transition and is conducive to changing the user's sleeping posture; by providing an arc-shaped protrusion, the user will not easily fall into the supine pillow when sleeping on the side, thereby ensuring the user's good side sleep; and when the user sleeps on the back, the hollow structure is designed to prevent interference with the user's head, and at the same time, the supine pillow is lower than the side pillow, so the user can ensure a good supine sleep.

[0075] Since the bilateral cervical pillow designed by the above scheme is only obtained by taking photos of the target user, it does not take into account that the target user will press down the part in contact with the cervical pillow during actual use, causing the height of the contact part to change, which will affect the target user's sleeping comfort to a certain extent. Therefore, it is necessary to compensate for the height of the contact part.

[0076] See also Figure 5 The contact portion may include a head region and a neck region, wherein the head region is the region where the head contacts the cervical pillow, and the neck region is the region where the neck contacts the cervical pillow.

[0077] As a preferred embodiment, after obtaining the supine cross-sectional profile and the lateral cross-sectional profile, the method further includes:

[0078] The first compensation amount of the neck area height in the supine cross-sectional profile is determined based on the following formula:

[0079]

[0080] In the formula, h 11 is the first compensation amount, h 1 is the height of the neck area in the supine cross-sectional profile before compensation, F 1 is the neck pressure, S 1 is the contact area between the neck and the cervical pillow, and E is the elastic modulus of the material of the cervical pillow;

[0081] Adding the first compensation amount to the height of the neck region in the cross-sectional profile of the supine position to obtain a final height of the neck region in the cross-sectional profile of the supine position;

[0082] The second compensation amount of the head area height in the lateral position cross-sectional profile is determined based on the following formula:

[0083]

[0084] In the formula, h 21 is the second compensation amount, h 2 The height of the head area in the lateral decubitus cross-sectional profile before compensation, F 2 is the head pressure, S 2is the contact area between the head and the cervical pillow, and E is the elastic modulus of the material of the cervical pillow;

[0085] The second compensation amount is added to the height of the head region in the lateral-lying position cross-sectional profile to obtain a final height of the head region in the lateral-lying position cross-sectional profile.

[0086] In this embodiment, by performing height compensation for the neck area height in the supine position cross-sectional profile and the head area height in the lateral position cross-sectional profile respectively, the actual height before compression can be obtained, so that the target user can get a more comfortable experience when lying on the cervical pillow, that is, cervical spondylosis can be effectively treated.

[0087] Furthermore, considering that cervical spondylosis requires enhanced support for the neck, the comfort of the contact part must also be considered, that is, the contact part should be soft, the whole should have a supporting effect, and the overall compression amplitude should not be too large after being compressed. Therefore, two materials can be selected, the part in contact with the human body uses a material with a smaller hardness, that is, a smaller elastic modulus, and the lower layer or middle layer uses a material with a larger hardness, that is, a larger elastic modulus.

[0088] As a preferred embodiment, after obtaining the supine cross-sectional profile and the lateral cross-sectional profile, the method further includes:

[0089] The height of the cervical region in the final supine cross-sectional profile is determined based on the following formula:

[0090]

[0091] In the formula, h 10 is the height of the cervical region in the final supine cross-sectional profile, h 1 h is the height of the upper soft material area in the supine cross-sectional profile before compensation. 2 To compensate for the height of the lower hard material area in the supine cross-sectional profile, E 1 is the elastic modulus of the upper soft material, E 2 is the elastic modulus of the underlying hard material, S 1 is the contact area between the neck and the cervical pillow, F 1 For neck pressure;

[0092] The height of the head area in the final lateral cross-sectional profile is determined based on the following formula:

[0093]

[0094] In the formula, h 20 is the height of the head area in the final lateral decubitus cross-sectional profile, h 3 The height of the upper soft material area in the lateral position cross-sectional profile before compensation, h 4To compensate for the height of the lower hard material area in the lateral cross-sectional profile before compensation, S 2 is the contact area between the head and the cervical pillow, F 2 In this embodiment, the neck area height in the final supine cross-sectional profile and the head area height in the final lateral cross-sectional profile are obtained by the above formula, which can ensure both enhanced support for the target user's neck and comfort of the contact part for the target user.
