The present invention relates to a smart sleep device.

A person sleeps for an average of 6 to 8 hours a day, and the quality of sleep affects a person's feeling of fatigue during activity. Therefore, interest in 'how good quality sleep' rather than 'how long enough time to sleep' is constantly increasing, and various devices for users to sleep in comfortable postures are being developed.

During sleep, people unconsciously move their bodies to distribute body pressure, regulate body temperature, and promote blood circulation. At this time, a part of the body where pressure is concentrated may occur due to an individual posture taken naturally, and a person unconsciously turns over to improve discomfort in the part where pressure is concentrated. Tossing and turning like this disrupts sleep.

1 and 2, the smart sleep device 10 according to an embodiment of the present invention includes an air-filled mattress 100 on which a user sleeps. Unlike conventional spring mattresses and latex mattresses, the air-filled mattress 100 fills the inside with air to form a predetermined size. The air filled in the air-filled mattress 100 may have a constant air pressure and stably support the user's body. However, if necessary, the air pressure of the air-filled mattress 100 may be adjusted. That is, the shape of the air-filled mattress 100 may change according to the user's height, weight, and posture. Changes in the shape of the air-filled mattress 100 will be described later.

The air-filled mattress 100 may include a mattress body 110 and a sensing layer 120 . The mattress body 110 may have a plurality of air rooms (not shown). The plurality of air rooms may be formed at locations corresponding to a plurality of zones described later. That is, a plurality of air rooms may be formed in a number corresponding to the plurality of zones. The air pressure of each of the plurality of air rooms may be individually controlled, and the air-filled mattress 100 may be deformed to have a shape optimized for the user by the individually air pressure-controlled air rooms. Thus, since the air-filled mattress 100 has a shape that can most stably support the user's sleeping posture, the smart sleep device 10 has the advantage of improving the quality of the user's sleep. A process of adjusting the air-filled mattress 100 according to the user's sleeping posture will be described later.

In addition, the air-filled mattress 100 may include a sensing layer 120 that senses a user's sleeping posture. A plurality of flexible pressure sensors 170 described later may be disposed on the sensing layer 120 . For example, in order to arrange a plurality of flexible pressure sensors 170 in the sensing layer 120, the sensing layer 120 is a 225 square millimeter to 2,500 square millimeter grid of flexible printed circuit boards (flexible PCBs) are assembled. structure can be formed. The sensing layer 120 may be coupled to the mattress body 110 and detect the user's sleeping posture through the flexible pressure sensor 170 .

Hereinafter, the partitioned areas 130 of the air-filled mattress 100 will be described.

The air-filled mattress 100 may be partitioned into a plurality of preset zones 130 throughout the mattress. More specifically, the sensing layer 120 of the air-filled mattress 100 may be partitioned into a plurality of regions 130 . At least one flexible pressure sensor 170 may be disposed in each of the plurality of zones 130 . That is, the pressure applied to the air-filled mattress 100 by the user for each zone 130 may be measured by the flexible pressure sensor 170 disposed in each of the plurality of zones 130 . The measured pressure may be used as data for customizing the air-filled mattress 100 into a user-customized shape.

The plurality of zones 130 may all have the same area, or at least some of them may have different areas. At this time, the user generally starts sleeping by being positioned in the center of the bed. Accordingly, the area of the areas 130 of the air-filled mattress 100 where the user starts sleeping in the right position may be formed to have a relatively larger width than the areas of other areas 130 .

Referring to FIGS. 1 to 3 , zones 130 of the air-filled mattress 100 may be illustratively arranged in a 5×3 matrix form. That is, the zones 130 of the air-filled mattress 100 may include a total of 15 zones 130. However, the number of zones is arbitrary, and if necessary, a plurality of zones 130 such as a 5 × 5 matrix (25 zones), a 7 × 3 matrix (21 zones), or a 7 × 5 matrix (35 zones) can include For convenience of explanation, the uppermost zone on the left side is referred to as the first zone, and the lowermost zone on the right side is named the 15th zone.

As shown in FIG. 2 , at least some of the plurality of zones 130 may have different areas. Exemplarily, the first region, the third region, the seventh region, and the ninth region may have the first zone area. Also, the fourth area, the sixth area, the tenth area, and the twelfth area may have a second area larger than the first area. In addition, the 13th zone and the 15th zone may have a third zone area larger than the second zone area, and the second zone and the eighth zone may have a fourth zone area larger than the second zone area. there is. Also, the fifth zone and the eleventh zone may have a fifth zone area larger than the third zone area and the fourth zone area, and the fourteenth zone may have a sixth zone area larger than the fifth zone area. Meanwhile, the height of each area 130 may be formed to correspond to the body ratio of the user U. That is, the smart sleep device 10 according to an embodiment of the present invention includes an air-filled mattress 100 in which zones 130 are partitioned so that it can be applied to users U having various body types such as teenagers, adults, and seniors. can include

Meanwhile, as shown in FIG. 3 , the plurality of zones 130 may include main zones 140 and sub zones 150 . The main zones 140 may be formed in the central portion of the air-filled mattress 100 . The main areas 140 may be areas 130 that the body of the user U presses when the user U is positioned on the air-filled mattress 100 . Illustratively, the second zone, the fifth zone, the eighth zone, the eleventh zone, and the fourteenth zone may be the main zones 140 . More specifically, the second zone can be the first main zone 1401, the fifth zone can be the second main zone 1402, the eighth zone can be the third main zone 1403, The eleventh zone can be the fourth main zone 1404 and the fourteenth zone can be the fifth main zone 1405 .

At this time, the first main area 1401 is where the user's head is located, the second main area 1402 is where the user's shoulders are located, the third main area 1403 is where the user's waist is located, and the fourth main area is where the user's waist is located. 1404 may be the user's buttocks, and the fifth main region 1405 may be the user's legs.

Meanwhile, the sub-zones 150 may be formed adjacent to both sides of the main zones 140 . 1st sub-zone (1501, 1st zone), 2nd sub-zone (1502, 4th zone), 3rd sub-zone (1503, 7th zone), 4th sub-zone (1504, 10th zone), 5th sub-zone Sub-zone (1505, 13th zone), 6th sub-zone (1506, 3rd zone), 7th sub-zone (1507, 6th zone), 8th sub-zone (1508, 9th zone), 9th sub-zone (1509, twelfth zone) and a 10th sub-zone (1510, 15th zone) may be formed respectively. The sub-regions 150 may be pressed by the body of the user U when the user U changes his/her posture. For example, the user U may rotate clockwise or counterclockwise while sleeping. In addition, the user U may fold or unfold the body, and may roll leftward or rightward. Accordingly, when the user U is not positioned properly, the body of the user U may be located on the sub area 150 as well.

Meanwhile, each of the main zones 140 may have an area larger than that of each of the sub zones 150 corresponding to the same row. In general, the user U can lie down in the center of the air-filled mattress 100, and the main zones 140 formed in the center of the air-filled mattress 100 have more fine pressure than the sub-zones 150. analysis is needed Accordingly, since the main area 140 has a larger area than the area of each of the sub areas 150 in the corresponding row, the sleeping posture of the user U can be more accurately analyzed, and the smart sleep according to the present invention The device 10 has an advantage of providing an optimal sleep environment to the user U.

Hereinafter, the flexible pressure sensor 170 and the arrangement density per unit area in which the flexible pressure sensor 170 is disposed in the main zones 140 and the sub zones 150 will be described.

Referring to FIGS. 1 to 4 , flexible pressure sensors 170 may be disposed in main areas 140 and sub areas 150 . For example, the flexible pressure sensors 170 may be flexible thin-film pressure sensors having a 0.3 mm standard. The flexible pressure sensors 170 have a fast response speed and can sense static pressure and dynamic pressure. The flexible pressure sensors 170 may be individually formed in a module form.

The flexible pressure sensors 170 need to be intensively disposed in areas where the user U mainly applies pressure when he or she is sleeping. By intensively arranging the flexible pressure sensors 170 in the area where the user U mainly presses, it is possible to obtain detailed measurement values of the areas where the user U stays and provide the user U with an optimal sleeping environment. can do.

As described above, in order to provide an optimal sleep environment to the user U, the flexible pressure sensors 170 may be densely disposed in the main areas 140 . More specifically, the arrangement density per unit area of the flexible pressure sensors 170 disposed in at least some of the plurality of main zones 140 is the flexible pressure sensor 170 disposed in the plurality of sub zones 150 It may be greater than the batch density per unit area of Therefore, since the flexible pressure sensors 170 are densely disposed in the main areas 140 where the user U mainly lies down, the measurement values of the flexible pressure sensors 170 can be accurately obtained, and the user ( U) can provide an optimal sleeping environment.

On the other hand, in terms of body characteristics, when the user U is positioned in a straight posture on the air-filled mattress 100, about 70% of the total body pressure applied by contact of the user U's body is concentrated on the shoulders and hips has been That is, the pressure due to the weight of the user U is concentrated in the second main area 1402 and the fourth main area 1404 . Therefore, the arrangement density per unit area of the flexible pressure sensors 170 disposed in the second main zone 1402 and the arrangement density per unit area of the flexible pressure sensors 170 disposed in the fourth main zone 1404 are It may be greater than the arrangement density per unit area of the flexible pressure sensors 170 disposed in each of the main areas 1401 , 1403 , and 1405 excluding the main areas 1402 and 1404 .

Also, the flexible pressure sensors 170 disposed in at least some of the plurality of main regions 140 may be biased toward one side. Illustratively, in the case of the fifth main region 1405 where the leg of the user U presses, the pressure by the thigh portion is generally higher than the pressure by the extremity of the leg. Thus, within the fifth primary region 1405, the flexible pressure sensors 170 may be biased and placed more densely in the thigh portion than the distal leg portion. In this way, the body of the user U can be stably supported by detecting the main contact part of the body of the user U in detail.

Hereinafter, the air pressure adjusting unit 200 will be described.

The smart sleep device 10 according to an embodiment of the present invention includes an air pressure control unit 200. The air pressure control unit 200 may be electrically connected to the air-filled mattress 100 . The air pressure control unit 200 may supply power to the flexible pressure sensors 170 disposed on the air-filled mattress 100, and the flexible pressure sensors 170 may be pressed by the user U's body. Signals generated by the process can be collected. In some cases, the air pressure control unit 200 may include a temporary database unit (not shown) for temporarily storing the measured values of the flexible pressure sensors 170 in the arithmetic unit 300 to be described later. In addition, the air pressure control unit 200 may include a communication module for transmitting the measurement value of the flexible pressure sensor 170 to the calculation unit 300 . The communication module may be a wireless communication module, but is not necessarily limited thereto, and the air pressure control unit 200 and the calculation unit 300 may be connected by a communication cable.

Meanwhile, the communication module may receive an air pressure adjustment command (signal) from the calculation unit 300 . Accordingly, the air pressure control unit 200 may adjust the pressure (ie, air pressure) of the air-filled mattress 100 for each zone 130 in real time according to the calculation result of the operation unit 300 .

Illustratively, the air pressure control unit 200 may adjust the air pressure of the zone 130 in which the measurement value of the flexible pressure sensor 170 is determined to be high according to the calculation result of the operation unit 300 . The air pressure control unit 200 may inject air into the air-filled mattress 100 or discharge air from the air-filled mattress 100 . A commonly known means may be used as a means for injecting or discharging air of the air pressure control unit 200 .

The air pressure control unit 200 adjusts the air pressure of the air-filled mattress 100 in real time by the operation unit 300 to be described later, but may additionally include a configuration capable of being manipulated by the user U as needed. Illustratively, the air pressure control unit 200 may include a zone selector and an air control unit. A region (more precisely, an air room) to be adjusted for air pressure may be selected through the region selector, and the air pressure in the corresponding region may be increased or decreased through the air controller.

In the following, the calculation unit 300 will be described.

The smart sleep device 10 according to an embodiment of the present invention includes a calculation unit 300. The calculation unit 300 may perform a predetermined calculation based on the measured value of the flexible pressure sensor 170 . In this case, the calculation may mean optimizing the measurement value and imaging it as a grayscale pattern. A process of the calculation unit 300 optimizing the measured value and forming an image into a grayscale pattern will be described later. The computing unit 300 may be a server including a part that performs logical operations such as a microprocessor. Illustratively, the calculation unit 300 may be a portable terminal of the user U. However, the calculation unit 300 does not necessarily have a physical entity, and may be a cloud system capable of performing calculation functions.

Hereinafter, the calculation unit 300 optimizes the measurement value of the flexible pressure sensor 170, and controls the air pressure adjustment unit 200 according to the result of performing the calculation by imaging the optimized measurement value in a gray scale pattern. A process of providing an optimal sleep environment to the user U by adjusting the pressure of the air-filled mattress 100 will be described in detail.

5 is for explaining color blocks 500 included in a plurality of zones 130 in a smart sleep device 10 according to an embodiment of the present invention, and FIG. 6 is a smart sleep device according to an embodiment of the present invention. For explaining a process of optimizing the measured value of the flexible pressure sensor 170 in the sleep device 10, FIG. 7 shows the flexible pressure sensor 170 in the smart sleep device 10 according to an embodiment of the present invention. ) is to explain the process in which the measured value is imaged.

First, the color block 500 will be described with reference to FIG. 5 . The measured values of the flexible pressure sensor 170 measured in the plurality of zones 130 of the air-filled mattress 100 are optimized and measured by at least one color block 500 included in the plurality of zones 130. It can be expressed in achromatic colors. That is, the color block 500 may be a means for visually expressing the degree to which the user U presses the specific region 130 .

Meanwhile, the color block 500 may be formed in various sizes. The size of the color block 500 corresponds to the arrangement density of the flexible pressure sensors 170, and the size of the color block 500 may be smaller as the arrangement density of the flexible pressure sensors 170 increases. For example, an arbitrary area 130 may include a plurality of first color blocks 510 . The first color blocks 510 may have a first width. Also, an arbitrary area 130 may include a plurality of second color blocks 520 . The second color blocks 520 may have a second area that is about twice the first area. Meanwhile, the second color blocks 520 may have a rectangular shape in which a horizontal length is greater than a vertical length. Also, an arbitrary area 130 may include a plurality of third color blocks 530 . The third color blocks 530 may have a third area four times the first area. The third color blocks 530 may have a square shape in which the first color blocks 510 are collectively formed in two rows and two columns.

Since flexible pressure sensors 170 are concentrated in the second main zone 1402 and the fourth main zone 1404, the second main zone 1402 and the fourth main zone 1404 have the first color block 510 ) can be composed of In the second main area 1402 and the fourth main area 1404 , the pressure by the body of the user U is expressed in the most detail by the first color blocks 510 .

Meanwhile, the first main area 1401 and the third main area 1403 and the sub areas 1501 , 1503 , 1506 , and 1508 adjacent thereto may be composed of second color blocks 520 . Since the regions 130 correspond to the upper body of the user U, the pressure exerted by the user U's body is expressed in some detail by the second color blocks 520 .

In addition, the main regions and sub-regions (eg, the fifth main region 1405, the fifth sub-region 1505, and the 10th sub-region 1510) corresponding to the lower body of the user U are It may be composed of 3 color blocks 530 . Since the zones 130 correspond to the lower body of the user U, the pressure of the user U's body is expressed by the third color blocks 530 .

Hereinafter, a process of assigning a color to the color block 500 based on the measurement value of the flexible pressure sensor 170 will be described.

Referring to FIG. 6 , the calculation unit 300 may receive a measurement value of the flexible pressure sensor 170 from the air pressure adjusting unit 200 described above. Exemplarily, the measurement value of the flexible pressure sensor 170 may be at least one of a measurement time, a measurement location, and a measurement pressure. The measured value of the flexible pressure sensor 170 may be a measured pressure ranging from 0 to about 0.2 kgf/cm ² . The measured value of the flexible pressure sensor 170 may be replaced with a numerical value in an integer range having a predetermined range, and the arithmetic unit 300 may receive the replaced numerical value. Illustratively, the measured value of the flexible pressure sensor 170 may be replaced with a numerical value ranging from 0 to 4095 integers. The calculation unit 300 may directly receive the measurement value in kgf/cm ² unit and replace the measurement value with a numerical value in the range of an integer from 0 to 4095. As shown in FIG. 6 , the pressure P at the measurement location Z for each measurement time T is measured. However, the mentioned 'numerical value in the range of an integer from 0 to 4095' is only an example, and the size of the range may be applied differently if necessary.

Then, the measured pressure (P) can be optimized. The measured pressure (P) can be replaced with an optimized pressure (P') value. Illustratively, the measured pressure (P) substituted with a numerical value in the integer range of 0 to 4095 may be replaced with an optimized pressure (P′) value having a numerical value in the integer range of 0 to 255. That is, the optimized pressure P' may be a value for allocating a corresponding color in gray scale.

When the measured pressure P is optimized, a color corresponding to the optimized pressure P′ may be selected. The color may be an achromatic color having 256 different brightnesses. The selected color may be visually expressed by being assigned to the color blocks 500 . In this case, one color may be assigned to one color block 500 . A region 130 having a relatively large number of color blocks 500 may express the measured pressure in gray scale in more detail. As shown in FIG. 7 , the color selected in FIG. 6 is assigned to the first color block 510 at a corresponding position in the fourth main zone 1404 . The sleeping posture of the user U is displayed according to the brightness of the colors assigned to the color blocks 500 and the arrangement positions of the colors. As shown in FIG. 7 , it can be seen that the user U turns his body to the left side, puts his hands together, and sleeps with his feet bent to the right side while his legs are bent.

8 is for showing various measurement results imaged.

As shown in FIG. 8 , a measurement value of the flexible pressure sensor 170 may be imaged in a gray scale pattern. According to the imaged pattern, the sleeping posture of the user U may be analyzed. More specifically, the calculation unit 300 may match the imaged pattern with a preset sleeping posture. The preset sleeping posture may include a fetus type, a log type, a yearner type, a soldier type, a freefaller type, and a starfish type. The preset sleeping position may have a corresponding air pressure setting of the air-filled mattress 100 . The calculation unit 300 may control the air pressure adjusting unit 200 to apply the air pressure setting corresponding to the preset sleeping posture to the air-filled mattress 100 according to the analyzed result. The calculation unit 300 may control the air pressure control unit 200 to individually adjust the air pressure for each zone 130 of the air-filled mattress 100 . At this time, the arithmetic unit 300 controls a relatively high air pressure to be applied to the area 130 having the color block 500 having high brightness, and to the area 130 having the color block 500 having low brightness. It can be controlled so that a relatively low air pressure is applied to it. That is, the calculation unit 300 may control the air pressure adjusting unit 200 so that different air pressures are applied to at least some of the plurality of zones 130 corresponding to the preset sleeping posture.

Hereinafter, a method for controlling a smart sleep device according to an embodiment of the present invention will be described. On the other hand, in describing the method of controlling the smart sleep device, the contents overlapping with the aforementioned smart sleep device are briefly mentioned or omitted.

10 is a flowchart of a method for controlling a smart sleep device according to an embodiment of the present invention.

Referring to FIG. 10, the method for controlling a smart sleep device according to an embodiment of the present invention includes a measurement pressure acquisition step (S110), an imaging step (S120), a preset sleeping posture matching step (S130), and an air pressure adjustment step. (S140) is included.

In the step of obtaining the measured pressure ( S110 ), a pressure measurement value applied by the user's body is obtained with at least one flexible pressure sensor disposed for each area of the air-filled mattress. The air-filled mattress may be divided into a plurality of zones, and at least some of the zones may have different areas. In addition, the plurality of zones may include main zones that are pressed when the user is in an upright position, and sub zones formed adjacent to the main zones. Characteristics of the main zones and sub-zones are the same as those described above, and thus descriptions are omitted.

In the imaging step ( S120 ), the measurement pressure may be optimized, and the optimized measurement pressure may be imaged in a gray scale pattern. The process of optimizing the measured pressure is to express the obtained measured pressure in a numerical range of 0 to 255, and an achromatic color corresponding to the numerical range of 0 to 255 may be selected. Meanwhile, in the imaging step (S120), colors may be allocated in units of color blocks included in each zone. Accordingly, the position and strength of the user's body may be visually expressed.

In the preset sleeping posture matching step (S130), a preset sleeping posture corresponding to the imaged pattern may be matched. This matching process may be performed by a deep learning algorithm, and a preset sleeping posture most similar to the imaged pattern may be matched. A detailed description of the preset sleeping posture is the same as described above. Meanwhile, the deep learning algorithm may be learned by collecting measurement results of people of various weights and body shapes, and may match a preset sleeping posture optimized for a user's sleeping posture.

Thereafter, in the air pressure adjusting step ( S140 ), the air pressure of the air-filled mattress may be adjusted for each region so as to correspond to the preset sleeping posture by the calculating unit controlling the air pressure adjusting unit. In this case, a portion of the color block having high brightness may be increased in pressure, and a portion of the color block having low brightness may be reduced. Accordingly, the control method of the smart sleep device according to an embodiment of the present invention has the advantage of providing an optimal sleep environment to the user by adjusting the shape of the air-filled mattress to a shape optimized for the user's sleeping posture.
