[0002] Users basically wear shoes in their daily lives. Shoes provide safe protection to the user's feet without putting a burden on them. In recent years, shoes with special functions in addition to such basic shoe functions have been developed and released. For example, there are shoes that automatically apply electrical stimulation to the soles of the user's feet when the user wears the shoes and shoes that detect the user's walking pattern using a sensor. In this way, shoes have evolved from being simply a means for protecting the feet to being a wearable device equipped with various functions. Summary of the Invention [Problem to be solved by the invention]

[0003] An object of the present invention is to provide a shoe last device and a technique for controlling the shoe last device. [Means for solving the problem]

[0004] A shoe last device according to one embodiment includes a vibrator that generates vibrations, a pressure sensor disposed below the vibrator that measures pressure, and a controller that controls the strength of the vibrations generated by the vibrator based on the measured pressure.

[0005] The pressure sensor can be at least partially overlapped with the vibrator in a direction perpendicular to the bottom surface of the shoe last device.

[0006] The pressure sensor can be completely overlapped with the area of ​​the transducer in a direction perpendicular to the bottom surface of the last device.

[0007] The transducer can be completely overlapped with the area of ​​the pressure sensor in a direction perpendicular to the bottom surface of the last device.

[0008] The pressure sensor and the transducer may form a vertically hierarchical structure and have the same central position in a first direction.

[0009] The pressure sensor may be attached to the transducer at a lower portion of the transducer.

[0010] The transducer and the pressure sensor may be integrally formed.

[0011] A vibration frequency of the vibration generated by the vibrator may be different from a detection frequency for pressure detection of the pressure sensor.

[0012] The controller may control the transducer such that as the measured pressure increases, the strength of the vibration increases.

[0013] The controller may control the transducer such that if the measured pressure decreases, the strength of the vibration decreases.

[0014] The controller can set the intensity of the vibration to a first intensity when the measured pressure is a first pressure value, and can set the intensity of the vibration to a second intensity greater than the first intensity when the measured pressure is a second pressure value greater than the first pressure value.

[0015] The controller can determine the vibration strength corresponding to the measured pressure based on predefined pressure-to-vibration strength conversion information.

[0016] The vibrator is capable of generating vibrations of an intensity below the sensory threshold of a user wearing the shoe-like device.

[0017] The vibrator may include a first vibrator that generates vibrations at a position corresponding to the user's forefoot and a second vibrator that generates vibrations at a position corresponding to the user's rear foot, and the pressure sensor may include a first pressure sensor arranged below the first vibrator and a second pressure sensor arranged below the second vibrator.

[0018] The controller can determine a strength of a first vibration generated by the first oscillator based on the pressure measured by the first pressure sensor, and can determine a strength of a second vibration generated by the second oscillator based on the pressure measured by the second pressure sensor.

[0019] The strength of the first vibration and the strength of the second vibration may be different from each other.

[0024] The specific structural or functional description of the embodiment is disclosed for the purpose of illustration only, and may be modified in various forms. Therefore, the embodiment is not limited to the specific disclosed form, and the scope of the present specification includes modifications, equivalents, or alternatives within the technical spirit.

[0025] Although terms such as first or second may be used to describe multiple components, such terms should be construed only for the purpose of distinguishing one component from the other components. For example, a first component may be named a second component, and similarly, a second component may be named a first component.

[0026] When a component is referred to as being "coupled" or "connected" to another component, it should be understood that although it is directly coupled or connected to the other component, there may be other components in between.

[0027] The terms used in this specification are merely used to describe certain embodiments and are not intended to limit the present invention. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this specification, the terms "include" or "have" indicate the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and should be understood as not precluding the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0028] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention belongs. Commonly used predefined terms should be interpreted as having a meaning consistent with the meaning they have in the context of the relevant art, and should not be interpreted as idealized or overly formal unless expressly defined in this specification.

[0029] The shoe-type device described herein includes an electronic element capable of generating vibrations. For example, the shoe-type device includes a vibrator that generates physical vibrations based on a control signal to induce vibration noise. The vibrator is built into the shoe-type device and can provide a stimulation value below the sensory threshold to a user wearing the shoe-type device. Here, the sensory threshold indicates the minimum magnitude of stimulation for activating cells. The vibrator generates vibration noise having an intensity below the tactile threshold that can be detected by the sole of the user, thereby causing the phenomenon of stochastic resonance. The stochastic resonance phenomenon is, for example, a phenomenon in which measurement sensitivity to a signal to be observed is improved by adding white noise below the sensory threshold to a measuring device or sensory organ having a fixed sensory threshold. For example, the vibration noise generated by the vibrator of the shoe-type device amplifies the tactile signal transmitted to the sole of the user through the stochastic resonance phenomenon, thereby allowing the user to feel the sensation of the sole of the foot more sensitively. Due to this effect, the shoe-type device is useful for people who cannot feel normal sensations due to a dulled sensation in their feet.

[0030] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. In the description with reference to the accompanying drawings, the same reference numerals will be used to refer to the same components regardless of the reference numerals, and redundant description thereof will be omitted.

[0031] Fig. 1 is a perspective view of a shoe last device according to one embodiment, Fig. 2 is an exploded perspective view of a shoe last device according to one embodiment, showing an insole body partially cut open, and Fig. 3 is a cross-sectional view of a shoe last device according to one embodiment.

[0032] 1 to 3, a shoe last device 1 according to an embodiment includes a sole 10, a control device 20, and an upper 90. The sole 10 includes an outsole 11, a midsole 12, and an insole 13. In the following description, the longitudinal direction of the shoe last device 1 is indicated as the y-axis direction, the width direction of the shoe last device 1 as the x-axis direction, and the height direction of the shoe last device 1 as the z-axis direction. In this specification, the shoe last device 1 is described as having a shoe shape, but the scope of the embodiment is not limited thereto. For example, the shoe last device 1 may be realized in the shape of a sock, or may have a shape applied to a motion assist robot.

[0033] The outsole 11 forms at least a part of the bottom of the shoe last device 1. For example, the outsole 11 includes a bottom surface that comes into contact with the ground when the user wears the shoe last device 1. In the following, an embodiment in which the outsole 11 and the midsole 12 are distinguished from each other will be described, but the outsole 11 and the midsole 12 may be integrally formed. The midsole 12 may form at least a part of the lower outer shape of the shoe last device 1. The insole 13 may be attached inside the upper 90 and disposed above the midsole 12. The insole 13 includes a surface that comes into contact with the sole of the user's foot when the user wears the shoe last device 1, and is separated from the midsole 12.

[0034] In one embodiment, the insole 13 includes an insole body 131, a support layer 132, electronic elements, connecting lines 134, and a connector 135. The insole body 131 is placed on the upper surface of the midsole 12 and may be manufactured in various shapes. The support layer 132 is provided on the inside of the insole body 131 and supports the electronic elements and connecting lines 134. The connecting lines 134 electrically connect the electronic elements and the control device 20 to each other, and the connector 135 electrically connects each electronic element to the control device 20.

[0035] The electronic element may be disposed on an upper surface of the support layer 132, or the electronic element and the support layer 132 may be entirely disposed inside the insole body 131. However, the scope of the embodiment is not limited thereto, and a part of the electronic element may be exposed to the outside of the insole body 131 depending on the embodiment.

[0036] In one embodiment, the electronic device includes one or more vibrators 133a, 133b and one or more pressure sensors 143a, 143b. The vibrators 133a, 133b include, for example, a piezo motor or an eccentric vibration motor. The vibrators 133a, 133b can generate physical vibrations having a vibration strength equal to or less than a set maximum vibration strength. Here, the change in vibration strength may change irregularly like noise. The pressure sensors 143a, 143b are sensors that measure the pressure applied to the pressure sensors 143a, 143b, and can detect the plantar pressure transmitted from the sole of the foot when the user wears the shoe last device 1. The pressure sensors 143a, 143b may be, for example, a piezo pressure sensor or an FSR (force sensitive resistor) pressure sensor, and may be realized in a film form.

[0037] The pressure sensors 143a, 143b may be arranged below the positions where the transducers 133a, 113b are arranged, without being arranged separately from the transducers 133a, 133b. In one embodiment, the pressure sensors 143a, 143b at least partially overlap with the transducers 133a, 133b in a direction perpendicular to the bottom surface of the shoe last device 1. In this way, the pressure sensors 143a, 143b can form a vertical hierarchical structure with the transducers 133a, 133b.

[0038] Depending on the embodiment, the electronic elements may further include other sensors, for example inertial sensors such as acceleration sensors, gyro sensors, etc. The inertial sensors can be used to measure the movement of the shoe last 1 and / or the user wearing the shoe last 1.

[0039] The control device 20 is electrically connected to the electronic element and receives sensor data from the pressure sensors 143a, 143b and other sensors included in the electronic element. The control device 20 also transmits control signals to the transducers 133a, 133b for controlling the driving of the transducers 133a, 133b.

[0040] The control device 20 includes a case 21, a connection portion 22, a battery 23, and a controller 24. The case 21 has a shape corresponding to the receiving groove 121 formed in the midsole 12. The connection portion 22 may be provided with a terminal that electrically connects to the connection line 134 and disposed on the upper side of the case 21. The battery 23 supplies power required for the operation of the shoe last device 1. For example, the battery 23 supplies power to the electronic elements and the controller 24 and includes a rechargeable battery. The controller 24 includes one or more processors and controls the operation of the shoe last device 1. The controller 24 generates control signals for controlling the operation of the electronic elements. For example, the processor 24 generates control signals for controlling the vibrators 133a, 133b and control signals for adjusting the frequency and / or maximum vibration strength of the vibrations generated by the vibrators 133a, 133b based on the pressure measured by the pressure sensors 143a, 143b.

[0041] FIG. 4 is a plan view illustrating a relative positional relationship between an electronic element and a user-initiated device according to an embodiment.

[0042] 4, a shoe last device according to one embodiment includes a front vibrator 133a disposed at a front portion of a support layer 132, a rear vibrator 133b disposed at a rear portion of the support layer 132, a front pressure sensor 143a disposed below the front vibrator 133a, and a rear pressure sensor 143b disposed below the rear vibrator 133b. The front vibrator 133a generates vibrations (or vibration noise) at a position corresponding to the user's forefoot, and the rear vibrator 133b generates vibrations (or vibration noise) at a position corresponding to the user's rearfoot.

[0043] In one embodiment, the controller 24 can determine the strength of the vibrations generated by the front transducer 133a based on the pressure measured by the front pressure sensor 143a and the strength of the vibrations generated by the rear transducer 133b based on the pressure measured by the rear pressure sensor 143b.

[0044] When a user wears the shoe-shaped device 1, the strength and transmission characteristics of the vibration felt by the user may change according to the change in pressure on the sole of the foot. For example, when a user wearing the shoe-shaped device 1 is standing, the pressure applied to the sole of the foot is large, so it is necessary to apply a vibration of a large strength to the sole of the user's foot. If the user is sitting, the pressure applied to the sole of the foot is smaller than when the user is standing, and in this case, it is necessary to apply a vibration of a small strength to the sole of the user's foot. Thus, there is a close correlation between the pressure on the sole of the foot and the strength of the vibration applied to the sole of the foot. Therefore, in order to determine the appropriate vibration strength of the vibrators 133a and 133b, it is important to more accurately measure the pressure at the positions where the vibrators 133a and 133b are arranged.

[0045] In the shoe last device 1, the pressure sensors 143a and 143b are disposed below the vibrators 133a and 133b, so that the strength of vibration corresponding to the position where the sole pressure is measured can be determined efficiently. Also, by disposing the pressure sensors 143a and 143b below the vibrators 133a and 133b, the vibrators 133a and 133b can naturally play a role corresponding to the puck structure of the pressure sensors 143a and 143b.

[0046] 5A to 5E are diagrams showing an example of the arrangement relationship between a transducer and a pressure sensor according to one embodiment.

[0047] In one embodiment, the transducer and the pressure sensor may form a vertical hierarchical structure and may be at least partially overlapped with each other in a direction perpendicular to the bottom surface of the shoe last device. The vertical hierarchical structure between the transducer and the pressure sensor may take various forms.

[0048] Referring to FIG. 5A, the vibrator 512 and the pressure sensor 514 have the same width and the same center position in the first direction. For example, the vibrator 512 and the pressure sensor 514 may be arranged in concentric circles in the first direction. The first direction corresponds to the z-axis direction or the direction perpendicular to the bottom surface of the shoe last device. Referring to FIG. 5B, the pressure sensor 524 may be completely overlapped with the area of ​​the vibrator 522 in the direction perpendicular to the bottom surface of the shoe last device. In this case, the vibrator 522 has a larger width than the pressure sensor 524. Referring to FIG. 5C, the vibrator 532 may be completely overlapped with the area of ​​the pressure sensor 534 in the direction perpendicular to the bottom surface of the shoe last device. In this case, the pressure sensor 534 has a larger width than the vibrator 532. Referring to FIG. 5D, unlike FIG. 5A, the center positions in the first direction between the vibrator 512 and the pressure sensor 514 may not coincide with each other. Referring to FIG. 5E, there are multiple pressure sensors 554 and 556. In this case, all of the pressure sensors 554, 556 may be disposed below the transducer 552 and may overlap at least partially with the transducer 552 in a direction perpendicular to the bottom surface of the shoe last device.

[0049] Depending on the embodiment, the pressure sensor may be attached to the transducer at the bottom of the transducer. Alternatively, the transducer and the pressure sensor may be integrally formed with the pressure sensor disposed at the bottom of the transducer. In other words, the transducer and the pressure sensor may be realized in one module.

[0050] FIG. 6 is a diagram for explaining vibration control of a shoe last device for the forefoot and rearfoot of a user according to one embodiment.

[0051] 6, assume that the shoe last device includes a front transducer 614 located at a position corresponding to the forefoot of the user, and a rear transducer 612 located at a position corresponding to the rear foot of the user. A front pressure sensor 624 is located below the front transducer 614, and a rear pressure sensor 622 is located below the rear transducer 612.

[0052] If it is assumed that a user is standing on a flat ground while wearing a shoe-type device, the pressure applied to the rear foot is generally greater than that applied to the front foot. In such a case, the pressure detected by the rear pressure sensor 622 is greater than that detected by the front pressure sensor 624, and the controller of the shoe-type device can control the vibration strength of the rear oscillator 612 to be greater than that of the front oscillator 614. The controller can automatically control the vibration strength of each of the front oscillator 614 and the rear oscillator 612 based on the pressures detected by the front pressure sensor 624 and the rear pressure sensor 622, respectively. In this way, the shoe-type device can efficiently induce the stochastic resonance phenomenon that increases the sensitivity of the user's sole, taking into account the pressure state in the sole of the user's foot.

[0053] 7A to 7D are diagrams for explaining an example in which the strength of vibration of the vibrator is adjusted according to the magnitude of pressure measured by a pressure sensor according to an embodiment.

[0054] Figure 7A shows that the vibration strength of the transducer is adjusted linearly in response to the magnitude of the measured pressure, Figures 7B and 7C show that the vibration strength of the transducer is adjusted non-linearly in response to the magnitude of the measured pressure, and Figure 7D shows that the vibration strength is adjusted in a discontinuous manner in response to the magnitude of the measured pressure.

[0055] The shoe type device sets the strength of the vibration generated by the vibrator to be low when the magnitude of the measured pressure is low, and sets the strength of the vibration generated by the vibrator to be high when the magnitude of the measured pressure is high. In this way, the shoe type device controls the strength of the vibration of the vibrator according to the pressure state, and can reduce the discomfort felt by the user due to excessive vibration.

[0056] FIG. 8 is a flowchart for explaining a control method of a shoe last device according to one embodiment.

[0057] Referring to FIG. 8, in step S810, the shoe mold device measures pressure using a pressure sensor disposed under the vibrator. In step S820, the controller of the shoe mold device adjusts the strength of vibration generated by the vibrator based on the pressure measured in step S810. In one embodiment, the controller controls the vibrator so that the strength of the vibration of the vibrator increases when the measured pressure increases, and controls the vibrator so that the strength of the vibration decreases when the measured pressure decreases. The controller can adjust the strength of the vibration by controlling the output of a motor included in the vibrator. The controller automatically adjusts the strength of the vibration of the vibrator in response to the measured pressure change.

[0058] In one embodiment, when the shoe-type device includes a first transducer that generates vibrations at a position corresponding to the forefoot of the user, a second transducer that generates vibrations at a position corresponding to the rear foot of the user, a first pressure sensor provided below the first transducer, and a second pressure sensor disposed below the second transducer, the controller determines the strength of the first vibration generated by the first transducer based on the pressure measured by the first pressure sensor, and determines the strength of the second vibration generated by the second transducer based on the pressure measured by the second pressure sensor, where the strength of the first vibration and the strength of the second vibration may be different from each other.

[0059] The relationship between the magnitude of the measured sole pressure and the vibration strength of the vibrator set based on the pressure may have a continuous / discontinuous relationship or a linear / non-linear relationship. In one embodiment, the controller can determine the vibration strength corresponding to the measured pressure based on the defined pressure-vibration strength conversion information, and control the vibrator so that vibration of the determined vibration strength is generated.

[0060] The shoe type device can reduce battery consumption of the shoe type device by adjusting the vibration strength of the vibrator according to the pressure measured against the sole of the user's foot, and can efficiently induce the stochastic resonance phenomenon. In addition, when the pressure on the sole of the foot is low, the shoe type device can prevent the user from feeling uncomfortable due to vibration strength that is stronger than necessary by applying vibrations of appropriate strength corresponding to the low pressure to the sole of the user's foot.

[0061] On the other hand, since the vibration frequency of the vibration generated by the vibrator is different from the detection frequency for pressure detection of the pressure sensor, even if the pressure sensor is disposed below the vibrator, the vibration generated by the vibrator does not have a significant effect on the pressure measurement of the pressure sensor. However, according to an embodiment, the controller may use a filter to filter noise components due to the vibration of the vibrator from the pressure signal measured by the pressure sensor.

[0062] FIG. 9 is a block diagram showing the configuration of a control device of a shoe last device according to one embodiment.

[0063] 9, a control device 900 of the shoe last device includes a pressure sensor 910, a transducer 920, and a controller 930. The control device 900 operates while being built into the shoe last device.

[0064] The transducer 920 generates vibrations under the control of the controller 930. In one embodiment, the transducer 920 generates vibrations at an intensity below the sensory threshold of a user wearing the shoe last. The pressure sensor 910 is located below the transducer 920 and can measure pressure. In one embodiment, the transducer 920 and the pressure sensor 910 may be located in the insole of the shoe last.

[0065] The pressure sensor 910 may be at least partially overlapped with the transducer 920 in a direction perpendicular to the bottom surface of the last device. In one embodiment, the pressure sensor 910 may completely overlap the area of ​​the transducer 920 in a direction perpendicular to the bottom surface of the last device, or the transducer 920 may completely overlap the area of ​​the pressure sensor 910 in a direction perpendicular to the bottom surface of the last device. Depending on the embodiment, the pressure sensor 910 may be attached to the transducer 920 at a lower portion of the transducer 920, or the transducer 920 and the pressure sensor 910 may be formed integrally.

[0066] The controller 930 controls each component of the shoe last device. The controller 930 controls the strength of vibrations generated by the vibrator 920 based on the pressure measured by the pressure sensor 910. In one embodiment, the controller 930 controls the vibrator 920 to increase the strength of vibrations when the measured pressure increases, and to decrease the strength of vibrations when the measured pressure decreases. For example, the controller 930 sets the strength of vibrations to a first strength when the measured pressure is a first pressure value, and sets the strength of vibrations to a second strength that is greater than the first strength when the measured pressure is a second pressure value that is greater than the first pressure value.

[0067] In one embodiment, the controller 930 may use predefined pressure-to-vibration strength conversion information to determine the vibration strength of the transducer 920 in response to the measured pressure magnitude. The pressure-to-vibration strength conversion information may be defined in the form of a look-up table or the like as information defining the correspondence between the pressure magnitude and the vibration strength.

[0068] The controller 930 may individually control the strength of vibration of each oscillator 920 based on the magnitude of pressure of each pressure sensor 910 disposed on the last device. For example, the controller 930 may determine the strength of a first vibration generated by the first oscillator 920 based on the pressure measured by the first pressure sensor 910, and determine the strength of a second vibration generated by the second oscillator 920 based on the pressure measured by the second pressure sensor 910.
