It will be understood that the scope is not limited.

In addition, in the following description, a plurality of drawings will be simultaneously referenced and described in order to describe one technical feature or component constituting the invention.

1 is a side view of a shoe including a midsole capable of analyzing a walking posture of a user according to an embodiment of the present invention, and FIG. 2 is a shoe including a midsole capable of analyzing a walking posture of a user according to an embodiment of the present invention A cross-sectional side view, FIG. 3 is a view of an example in which a pressure sensor according to an embodiment of the present invention is included in the midsole, and FIGS. 4 and 5 are block diagrams between components according to an embodiment of the present invention, and It is a diagram of an example of an interface in which information is provided through an output means of a user terminal.

First, referring to FIGS. 1 and 2 , in the midsole 20 capable of analyzing a user's gait posture of the present invention, specifically, the outer skin covers the foot except for an opening that allows the user to put their feet and put on shoes. It is provided on the lower portion of the body 10 of the shoe, and relates to the midsole (20) included in the upper portion of the sole (not shown) in contact with the ground.

In general, a shoe may be basically composed of the above-described body 10 in which the outline of the shoe is specifically revealed, and the sole, which is a thin sole at the bottom in contact with the ground. However, the midsole 20 may be further included in shoes of the type of sports shoes that are mainly worn when activity is required according to the user.

The conventional midsole 20 is a configuration mainly for the purpose of absorbing or alleviating shock. The midsole 20 is further included to maximize the fit of the shoe, and in general, the cushion function is strengthened to maximize the activity when wearing the shoe.

In the present invention, by further including the above-described pressure sensor 22 in the midsole 20 having a cushion function, to which areas of the midsole 20 the load of the user's feet is applied, furthermore, to which areas relatively By detecting whether the load on the foot is further increased, it is possible to analyze the posture of the user when walking by measuring the direction in which the balance of the body is more skewed when the user walks.

The midsole 20 of the present invention is largely included in the lower portion of the midsole 20 to achieve the above object, and detects the magnitude of the load by the user's foot applied when the user walks. The communication unit 21 that receives the measured result value from the pressure sensor 22 and the pressure sensor 22 and transmits the received result value to the user terminal, thereby providing at least walking posture information through an output means of the user terminal. includes

Since the above-described pressure sensor 22 has a wide variety of conditions, ranges, and materials that must be measured when measuring pressure, there may be various types of the pressure sensor 22 . Often pressure is converted into an intermediate form, such as a displacement, after which the sensor converts the displacement into an electrical output such as voltage or current. Accordingly, the three most common types are a strain gauge transducer, a variable capacity transducer, and a piezoelectric transducer. not limited only to

When the above-described pressure sensor 22 is described with reference to FIGS. 2 and 3 , the pressure sensor 22 is included in the midsole 20 in being included in the midsole 20 , and is included in the lower portion of the midsole 20 , at least one of the midsole 20 . The area can contain many. 3 shows that the pressure sensor 22 is included in the front and rear axles of the foot in the midsole 20 as well. It can be understood that it can be installed in a number of areas that require measurement in measurement.

On the other hand, the above-described user terminal includes all terminals capable of accessing the Internet through a network and a wired/wireless access point, and includes a desktop computer, a tablet PC, a laptop, and a personal computer. It is preferable to be understood as any one of a computer (Personal computer), a smartphone (Smartphone), a personal digital assistant, and a mobile communication terminal (Mobile Communication Terminal). Any computing or communication device capable of performing may be used without limitation.

At this time, the communication unit 21 may further perform a function of storing information as one processor or controlling the pressure sensor 22 as another example, as well as a function as a medium of information transfer as described above. It would be better to understand that

Through the above-described configurations, the method of providing walking posture information to the user through the user terminal will be described in detail. When the user terminal provides the walking posture information to the user, the pressure sensor 22 received from the communication unit 21 is ) as the user's identification information pre-stored in the user terminal together with the result value measured from and transmits the walking posture information to the external management server 200 .

Referring to FIG. 4 , 100 is an example of an interface that provides walking posture information to the user through an output means of the user terminal. , you can see that it stores gender and age. In addition, the result value measured from the pressure sensor 22 is transmitted through the communication unit 21 so that it can be seen that the P1 user is more loaded with a relative load, especially on the front axle of the foot when walking.

Accordingly, if an example of obtaining information for determining whether a posture correction is necessary when walking is included in the above-described walking posture information to the user will be described, the user's body mass index can be obtained through height and weight information included in the user's identification information. (BMI: Body Mass Index) is obtained, and in some cases, the average result value or average measured from the pressure sensors 22 of different users having a height, weight, or body mass index similar to P1 from the user terminal or management server 200 to calculate or load information on the area of the foot that received more foot load with . At this time, if the foot of P1 is small compared to the height, more load may have been applied to the foot, or if P1 is walking with greater force on the foot during walking, more foot load may be applied. Of course, you can intervene. Through these processes, with reference to the image of the midsole 20 shown in the lower part of 100 and the text "forward weight", P1 not only information that more load was placed on the anterior axle of the foot, but also more Furthermore, compared to other users with similar physical conditions to P1, it is possible to obtain additional information about walking with a relatively greater load on the anterior axle of the foot.

Nevertheless, even if P1 walks with a relatively greater load applied to the anterior axis of the foot, especially when walking, the degree or difference in the degree of load applied is not significantly greater than that of other areas where the load is applied to the foot. Example For example, if the difference in pressure is more than 50 (an example value for arbitrarily explaining), it is determined that the user's gait posture is generally biased toward the front, and gait posture correction is required, so judgment information is derived as an abnormal gait posture On the other hand, if the difference is insignificant and less than 10 (an example value for arbitrarily explaining), it is true that the load on the foot is applied more to the anterior axis of the foot, but it is determined that it is not necessary to correct the walking posture. that can be derived.

In summary, the gait posture information can be said to be information that includes not only the previously stored identification information of the user, but also the derived judgment information after at least additional judgment information is derived based on the identification information. By storing the posture information also in the user terminal or the management server 200, it is preferable to accumulate and store the details so that the change in the load on the user's foot can be known so that the user can know whether the actual walking posture has been corrected.

By performing the functions of the above-described components, through the pressure sensor included in a plurality of the midsole 20, by measuring which area the load of the foot is applied to when the user walks, the pressure sensor 22 is primarily By detecting the area to which the load of the foot sensed through It is effective to accurately determine whether the user's posture when walking is correct by additionally sensing an area where the load on the foot is applied more.

On the other hand, the midsole 20 further includes a temperature sensor for measuring temperature or humidity, and the communication unit 21 receives the measured result value from the temperature sensor, and transmits the received result value to the user terminal, the user terminal Provides state information inside the body 10 through an output means of

At this time, when the state information inside the body is provided through the communication unit 21 and the output means of the user terminal, for example, the state information includes the result value measured from the temperature sensor, for example, the temperature inside the shoe. In addition to the measured value including the result value of 38 degrees, it is stored in the user terminal or management server 200 using the measured result value of 38 degrees and a preset reference temperature (for example, if it is 35 degrees or more, it is a hot state). It is considered that), and the state information derived by calculating whether the inside of the shoe is in a hot state or in a normal state is provided to the output means of the user terminal together.

If, in the above case, when it is determined that the inside of the shoe is in a hot state, as shown in FIGS. 1 and 2 , the body 10 includes a fan 30 on one side of the body 10, The temperature inside the body 10 may be lowered or the inside of the body 10 may be maintained in a dry state.

One side of the fan 30 is in contact with the outside, and the other side faces the inside of the shoe body 10 so that the air inside the body 10 of the shoe can flow and circulate with the outside. In addition, while lowering the temperature of the inside of the shoe through the operation of the fan 30, it is possible to maintain a dry state when the inside of the shoe is wet due to moisture.

In controlling the fan 30, a switch for turning on/off the fan 30 may be included in the body 10 of the shoe to control it, and if the communication unit 21 can perform a control function, the communication unit When 21 is higher than a preset reference temperature loaded from the user terminal or management server 200 using a temperature value, which is a result value measured from the temperature sensor, it is possible to control to automatically drive the fan 30, As another example, when the user terminal receives the state information of the inside of the shoe body 10 from the communication unit 21, the user terminal or the management server using a temperature value that is a result value measured from a temperature sensor included in the state information. When stored in 200 and higher than the preset reference temperature, driving information for the fan 30 is transmitted to the communication unit 21 to drive the fan 30, and when the temperature is lower than or equal to the preset reference temperature again It is possible to stop driving of the fan 30 by transmitting driving information for the fan 30 .

In addition, on the other hand, a heating wire (eg, a nichrome wire) may be further included on either side of the fan 30 so that dry warm air is introduced when it is cold. At this time, in order to supply current to the fan 30 and the heating wire, a battery may be added to the midsole 20 or the sole, or a piezoelectric element may be included to continuously generate power according to the user's foot to supply power. As there is, the present invention does not limit the technology and method with respect to the operation method and power supply method of the fan 30 and the heating wire.

In addition, the fan 30 capable of performing the above-described functions is, in particular, in the concave portion, which is a concave area of the sole of the foot among the areas in contact with the midsole 20 of the body 10 of the shoe, or the front axle portion, which is the area in which the user's toes come in contact. is installed

Limiting the position where the fan 30 is included in this way is to consider the case where the user sweats a lot due to activities such as exercise. Since it is an area that does not exactly fit the user's feet and creates a certain empty space, by installing the fan 30 in this area, the inflow of air through the empty space inside the shoe body 10 can be made more smoothly. , it is possible to maximize the drying function of the inside of the shoe.

Of course, in addition to this, various techniques for controlling the driving of the fan 30 may be used, and the present invention is not limited thereto in the driving method, principle, and technology.

That is, by including the fan 30 in the shoe including the midsole 20, which achieves the purpose of accurately determining whether the user's posture when walking is correct, it is possible to remove moisture from the inside of the shoe and maintain a dry state continuously. Thus, there is an effect of allowing the user to wear the shoes in a comfortable state whenever they wear the shoes.

On the other hand, referring to FIGS. 2 and 5 , the midsole 20 of the present invention includes a contact sensor 23 that detects an area where the user's foot is in contact, and the user terminal receives the user's response from the contact sensor 23 . By receiving the area or distribution information of the area in which the foot contacts the midsole 20 and comparing the area or distribution information with the size information of the midsole 20 pre-stored in the user terminal, information on whether or not a shoe replacement is necessary is provided to the user It is provided through the output means of the terminal.

As shown in FIG. 2 , the contact sensor 23 is preferably included in the upper portion of the midsole 20 so as to be in contact with the user's foot. The contact area or distribution between the user's foot and the midsole 20 is sensed through the contact sensor 23, and this is compared with the size of the shoe the user is wearing.

110 of FIG. 5 is an example of providing information on the area, distribution or non-contact area, and distribution between the user's foot and the midsole 20 through the contact sensor 23 through a visual interface. In one area of the front axle, there is an area where the foot of the user P1 has not touched, so that the size information of the midsole 20 or the size of the shoe input at the time of storing the identification information of the foot size of P1 and the P1 is finally compared between the size information of the shoe. By deriving result information on whether replacement is necessary, information on whether the size of the shoe needs to be changed is provided to the user.

At this time, in deriving result information on whether or not shoe replacement is finally necessary by comparing the size information of the midsole 20 or the shoe size input together at the time of storing the foot size of P1 and the identification information for P1, the user Comparing with the area of the midsole 20 included in the size information, the proportion of the area in contact with the feet is calculated, and when the ratio is equal to or smaller than the ratio pre-stored in the user terminal or management server 200 ( For example, 80%) the size of the shoe is considered large compared to the user's foot.

Or, at the same time, even when the shoe is larger than the user's foot, it is also possible to provide information on whether the front axle part of the foot is more loose or the rear axle part is loose.

This is in consideration that even if the size of the shoe is not suitable compared to the size of the user's foot, the posture during walking may be abnormal, and by further including the contact sensor 23 in the midsole 20, By detecting the area where the user's foot comes into contact with the midsole 20 and providing information about the detected area to the user, it is possible to directly visually check whether the user wears a shoe that fits his/her foot, so that the need for replacement of the shoe or the need for replacement of the shoe in the future In addition to the effect of providing more information on things to refer to when purchasing shoes, the purpose is to prevent the user from losing the balance of their posture while walking by wearing shoes of the correct size.
