Abstract
Description
Technical Field
[0001] The invention relates to the field of posture correction, in particular to a posture sensing feedback sheet and a composition and a body-fitting article thereof. Background Art
[0002] Hunchback, hunched back and forward neck are very common unhealthy postures of the human body. The human body may develop bad habitual postures due to insufficient strength of the corresponding muscle groups or lack of correction reminders, which affects the image and health.
[0003] The correction products currently available on the market generally use the principle of "pulling from behind", that is, using a strap to provide an additional pulling force on the back, pulling the shoulders and back of the human body backwards, thereby achieving posture correction. This product has the following disadvantages:
[0004] Disadvantage 1: When in use, the back of the human body is continuously pulled strongly, which limits the flexibility of human movement. If the pulling force is reduced, the correction effect will be weakened.
[0005] Disadvantage 2: Regarding the strong pulling mentioned above, the fulcrum of most products is based on tightly wrapping the human body, which affects the comfort of the human body; the fulcrum of a small number of products is the attached hard mechanical structure, which increases the weight of the human body and also affects the comfort of the human body.
[0006] Disadvantage 3: The form of external force correction does not cultivate the habit of the human body to actively use force to maintain posture, but it is easy to make the human body dependent. Once it is removed, for example, in the summer when wearing less clothes, it is stopped for the sake of beauty, and the bad posture is easy to reappear.
[0007] Disadvantage 4: For reasons of comfort and aesthetics, the method of pulling from behind can only correct hunchback and hunched back below the neck. It still cannot correct the common forward neck posture.
[0008] In addition, there are a few designs that use sensors to monitor the curvature of the human spine, and then transmit and convert electrical signals to eventually form a warning signal. The structure is complex and the cost is high. Summary of the invention
[0009] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a posture sensing feedback sheet and its composition and body-fitting articles, so that it can be attached to the skin of the shoulders and back of the human body. When the curvature of the body surface in the corresponding area reaches the triggering degree, the burrs inside it extend and contact the skin, and the tactile stimulation is used to realize the reminder function, thereby helping the human body to develop the habit of spontaneously exerting force to maintain a good posture. And because it does not rely on external force traction, it does not affect the flexibility of human body movements when worn. No electrical signals and sensors are used, the structure is simple, and the production cost is low.
[0010] The present invention provides a posture sensing feedback sheet (hereinafter referred to as "feedback sheet"), which is composed of two layers of substrates, including an inner sheet close to the skin and an outer sheet correspondingly far from the skin. The inner sheet and the outer sheet are bonded at both ends in the length direction to form two connecting sections, and there is an unbonded separation section between the two connecting sections. In the separation section, the outer sheet has burrs protruding toward the inner sheet. Both the inner sheet and the outer sheet are made of flexible and bendable materials. For both the inner sheet and the outer sheet, the side facing the skin is called the inner side, and the back side is called the outer side.
[0011] In the above technical solution, when the inner sheet and the outer sheet are fixedly connected at both ends in the length direction by the connecting section, the separating section will generate a gap between the outer surface of the inner sheet and the inner surface of the outer sheet according to the length difference between the two surfaces.
[0012] In the above technical solution, since the inner sheet and the outer sheet both have a certain thickness, when the separation section is bent, the inner sheet and the outer sheet of the separation section will be elastically bent and deformed, and the inner surface and the outer surface of each sheet will have a length difference due to the bending. At the same time, the length difference between the two contacting surfaces of the outer surface of the inner sheet and the inner surface of the outer sheet will also change, so that the gap between the two contacting surfaces will change.
[0013] In the above technical solution, the outer sheet has burrs protruding toward the inner sheet in the separation section. When the gap between the inner sheet and the outer sheet in the separation section is small, the burrs pass through the pores at the corresponding positions of the inner sheet and reach the outside of the inner surface of the inner sheet. At this time, the human skin in contact with the inner surface of the inner sheet will feel the stimulation reminder of the burr characteristics. When the gap between the inner sheet and the outer sheet is large, the outer sheet will drive the burrs to withdraw in the outward direction, thus eliminating the stimulation reminder to the human skin. When the inner sheet is a textile or a woven fabric, the gaps between the threads are the pores.
[0014] In the above technical solution, the respective lengths and relative lengths of the inner and outer sheets of the separation section are different in different areas according to the curvature of the skin surface that the corresponding area is intended to remind. By controlling the original length and the original length difference of the inner and outer sheets of the separation section, the desired correlation change between the curvature of the separation section and the size of the gap between the inner and outer sheets can be obtained within a suitable range.
[0015] In the above technical solution, the inner and outer sheets can be relatively fixed in the connecting section by common fixing methods such as non-adjustable sewing and bonding, or by adjustable position connection methods such as Velcro and adjustment buckles.
[0016] In the above technical solution, in order to obtain a sufficient gap, a sufficient length of the separation section is required. However, in actual use, because the feedback sheet is located on the human body surface, it will be covered by clothes and exert pressure on the outer sheet, so it is impossible to ensure that the maximum gap is generated at the specific required body surface position. For this reason, a gap limiting layer or a gap limiting sleeve can be added to the burr-free part of the separation section. The separation section covered by the gap limiting layer / sleeve basically does not produce a gap, and the gap generated by the length difference between the inner and outer sheets of the separation section is migrated and limited to the uncovered burr-containing part. Thereby, the burrs are concentrated in the most sensitive areas of the body surface, reducing the distribution range of the burrs and the number of burrs required for production, which helps to enhance the tactile stimulation caused by a small amount of local burrs on the basis of reducing costs.
[0017] The aforementioned feedback sheet only includes two connecting sections at both ends and a corresponding separation section in the middle, so it can only monitor the curvature of a section of the skin on the surface in one direction. By integrating multiple feedback sheets onto a common substrate to form a feedback sheet composite, it is possible to simultaneously monitor the curvature of the skin on the surface in multiple sections and directions. The connecting substrate can be an additional sheet, or it can be obtained by expanding the original inner sheet, outer sheet, and gap limiting layer of the feedback sheet.
[0018] By connecting the above-mentioned feedback sheet or feedback sheet combination to a close-fitting garment (such as an elastic band or underwear) for positioning on the human body, each feedback sheet can be accurately positioned in the target area of the body surface and closely fit with the body surface, thereby obtaining a body posture sensing feedback close-fitting garment, which can realize the functions of real-time monitoring and tactile feedback of the posture of the corresponding area of the human body. Among them, when using an elastic band for fixing, the feedback sheet or feedback sheet combination is located behind the human body, one end of the elastic band is connected to the base of the feedback sheet or feedback sheet combination, and the other end of the elastic band is put on the shoulders, and the elastic band can be made of elastic and retractable materials; when using underwear for fixing, the base of the feedback sheet or feedback sheet combination is connected to the corresponding area of the inner surface of the underwear by sewing, Velcro, etc.
[0019] The body posture sensing feedback sheet and its composition and body-fitting article of the present invention have the following beneficial effects:
[0020] The user can feel the tactile feedback of bad posture in real time. Creatively use tactile feedback instead of external pulling force to correct bad posture of the human body, avoiding the restriction of human movement flexibility. Creatively realize the reminder of spontaneous force of the human body, which helps to cultivate posture habits. And it can remind the forward neck posture. The structure is simple and applicable to a wide range of environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.
[0033] The present invention aims to propose a design that uses tactile feedback to remind the human body to correct bad postures, thereby avoiding the restriction of human body movements by strong external forces of existing products and avoiding the human body's dependence on strong external force correction.
[0034] The technical solution proposed in the present invention takes the curvature of the human body's skin as a trigger condition, and the interlayer gap between the inner and outer sheets of the separated section of the feedback sheet as a conversion condition for the curvature, and uses the burrs located on the inner surface of the outer sheet and protruding toward the inner sheet as tactile feedback that stimulates the skin on the body surface, thereby realizing complete posture monitoring and feedback functions.
[0035] In accordance with the feedback sheet and feedback sheet combination, each feedback sheet can be positioned at a target monitoring position on the human body surface by utilizing elastic bands or tensioning underwear.
[0036] The specific structure of the above-mentioned inventive concept is shown in the following figures:
[0037] In each of the figures, the thickness of the inner sheet 110 is greater than that of the outer sheet 120. This is only for the convenience of intuitive identification and is not a practical requirement.
[0038] Figure 1 Schematic diagram of the structure of the embodiment 1 of the body posture sensing feedback sheet of the present invention. In the figure, the feedback sheet 100 is composed of two layers of flexible and bendable substrates, namely, an inner sheet 110 and an outer sheet 120. At both ends in the length direction are two connecting sections 130 fixed by seams or Velcro, and between the two connecting sections 130 is a separation section 140. There is a gap 150 naturally between the inner sheet 110 and the outer sheet 120 in the separation section 140. There is a burr 121 protruding toward the inner sheet 110 at a certain position of the outer sheet 120 of the separation section 140. At the position of the inner sheet 110 corresponding to the burr 121, there is a pore 111 that allows the burr 121 to penetrate.
[0039] Figure 2 and Figure 3 The two figures are schematic diagrams showing the principle that the feedback sheet 100 of the present invention can generate tactile feedback according to the curvature of the skin. The two figures are applicable to the embodiment 1, and the length of the inner sheet 110 in the separation section 140 is shorter than the length of the outer sheet 120.
[0040] exist Figure 2 In the state shown, the inner sheet 110 of Example 1 is relatively straightened, and the outer sheet 120 is arched into an arch shape, and the height of the arch shape is the maximum value of the gap 150 between the two layers. At this time, the gap 150 is relatively large, and the length of the burr 121 is not enough to penetrate the pore 111. The skin on the inner surface 110a of the inner sheet 110 cannot feel the burr 121.
[0041] exist Figure 3 In the bending state shown, the bending direction is toward the inner sheet 110. At this time, because the inner sheet 110 has thickness, after bending, a surface length difference will be generated between the inner surface 110a with a small radius and the outer surface 110b with a large radius. At this time, the length difference between the arc length of the outer surface 110b of the inner sheet 110 and the arc length of the inner surface 120a of the outer sheet 120 is greater than Figure 2The length difference in the straight state shown is smaller, and the maximum value of the gap 150 generated by the arc length difference is smaller than Figure 2 At this time, the burr 121 passes through the pore 111 and extends from the inner surface 110a of the inner sheet 110. At this time, the skin located on the inner surface 110a of the inner sheet 110 feels the tactile stimulation of the burr 121.
[0042] Figure 4 The feedback sheet 100 of the embodiment 2 is shown. Considering that in the implementation environment, the feedback sheet 100 is located between the human body and the clothing. The arched outer sheet 120 will be squeezed by the clothing, which is likely to cause the arc of the outer sheet 120 to deform, and the position of the maximum gap will change in an uncertain manner. Therefore, in order to accurately align the position of the maximum gap with the burr 121, on the basis of embodiment 1, embodiment 2 adds a gap limiting layer 160 to the outer surface 120b of the outer sheet 120 of the separation section 140, which spans the outer sheet 120 and is connected to the inner sheet 110, and only exposes the outer sheet 120 near the burr 121. Because the length of the exposed arc is small, even if the outer sheet 120 is squeezed by the clothing, the position of the maximum gap will not change significantly. At the same time, the gap limiting layer 160 can also change its position relatively, located on the inner surface 110a of the inner sheet 110, spanning the inner sheet 110 and connected to the outer sheet 120, and the principle and effect are the same.
[0043] Figure 5 The third embodiment of the feedback sheet 100 of the present invention is shown. Based on the same principle as the second embodiment, the third embodiment adds a sleeve-shaped gap limiting sleeve 161 at the position of the burr-free 121 of the separation section 140 outside the entire inner sheet 110 and the outer sheet 120, so as to achieve Figure 4 In the second embodiment shown, the gap limiting layer 160 is used to align the maximum gap with the position of the burr 121 .
[0044] Figure 6 to Figure 7 The embodiment 4 of the feedback sheet of the present invention is shown. In the embodiment 1, the connection section 130 fixes the connection between the inner sheet 110 and the outer sheet 120 in the form of a seam or Velcro. In order to make the parameter state of the feedback sheet 100 flexibly adapt to the specific state of the curvature of the human body surface in the corresponding area, the length difference between the inner sheet 110 and the outer sheet 120 in the separation section can be changed, that is, at the connection section 130, a connection method that can adjust the relative position or position of the inner sheet 110 and the outer sheet 120 is used, such as Velcro, or an adjustment buckle 131 is used as shown in the embodiment 4. In the embodiment 4, the inner sheet 110 and the outer sheet 120 are formed by bending the same substrate material, passing through the adjustment buckle 131 at the bending point to form a connection section 130, and then the two ends are sewn or Velcro is used to form another connection section 130. By moving the inner sheet and outer sheet materials at the adjustment buckle 131, the length difference between the inner sheet 110 and the outer sheet 120 of the separation section 140 can be changed.
[0045] Figure 8 This is the embodiment 5 of the feedback sheet 100 of the present invention. The inner sheet 110 and the outer sheet 120 of the feedback sheet 100 are both made into a cross shape. Among them, by connecting the connecting sections 130 of multiple feedback sheets 100 in multiple directions, a radial surface is formed, thereby obtaining multiple separation sections 140. Burrs 121 are respectively provided on each separation section 140, so as to realize the monitoring and feedback of the curvature at multiple positions. When this feedback sheet 100 is fixed at a suitable position in the center of the back of the human body, the curvature of multiple body surfaces can be monitored simultaneously.
[0046] Fig. 9 Embodiment 6 of the present invention discloses a posture sensing feedback sheet composition. It connects multiple feedback sheets 100 to a common substrate 200, and also realizes the multi-directional and multi-site monitoring function of embodiment 6. This embodiment is suitable for the production of multiple identical feedback sheets 100, reducing cutting waste.
[0047] The structure of the feedback sheet and examples of the combination of the feedback sheets according to the present invention have been described above.
[0048] Fig.10 The figure is a schematic diagram of an application scenario of wearing and fixing the posture sensing feedback sheet composition shown in Example 6 on a human body 300. The elastic band 301 is connected to the base 200 of the feedback sheet composition. The feedback sheet 100 assembly is placed on the back, and the elastic band 301 is put on the left and right shoulders to form a first posture sensing feedback undergarment, so that each feedback sheet 100 in the posture sensing feedback sheet composition corresponds to the body surface to be monitored.
[0049] Fig.11 It is also a schematic diagram of an application scenario of wearing and fixing the posture sensing feedback sheet combination shown in Example 6 on a human body. Each feedback sheet 100 is directly connected to a suitable position on the inner surface of the underwear 302. When wearing the underwear 302, each feedback sheet 100 is positioned at the body surface to be monitored to form a second posture sensing feedback undergarment, and feedback the curvature of the corresponding body surface. The technical principles and key technical features of the present invention are as follows:
[0050] The core of the present invention is to sense the separation section between the two connection sections of the feedback sheet and the burrs on the inner surface of the outer sheet in the separation section.
[0051] Based on the above, if Figures 1 to 10 As shown in the figure, when the curvature of the separation section between the two connecting sections changes, the burrs inside the outer sheet of the separation section will follow the change of the gap between the inner sheet and the outer sheet and be in two states: "penetrating the inner sheet and reaching the skin" or "not reaching the skin". The "reaching the skin" state can produce tactile stimulation to the human body, reminding the human body to correct the posture.
[0052] All existing posture correctors cannot achieve the purpose and function of the present invention: to realize the reminder function by tactile feedback, reminding the human body to actively adjust the posture, without relying on external force to achieve correction, and without affecting the flexibility of human activities.
[0053] Therefore, the present invention discloses "bending deformation" and "tactile reminder" as the core points.
