Description
Smart String Bed System
[0001] The present invention relates to a smart string bed system, and more particularly, to a smart string bed system that analyzes a user's sleeping posture using a body pressure sensor during sleep on a mattress equipped with a 3D string, and adjusts the air pressure (hardness) of the 3D string in real time based on the analysis results to induce and maintain a good night's sleep for the user.
[0002] Generally, a bed is a piece of furniture designed for users to sleep on, and is assembled by loading and securing a mattress onto a bed frame made of metal or wood.
[0003] Here, the mattress can be detachably attached to the bed frame so that it can be replaced with another mattress of the same or similar specifications.
[0004] The above mattress is a bed component that actually comes into contact with the user's body, and in order to provide comfort to the user, a plurality of spring members are placed inside, and the plurality of spring members are woven together using steel wires or the like to have a predetermined external shape, and then the external shape is finished with a mattress cover made of fabric or cushion material.
[0005] In order to diversify their functionality, recent mattresses are not manufactured using the traditional spring material method, but rather using materials with improved elastic properties such as latex or sponge.
[0006]
[0007] Meanwhile, people unconsciously move their bodies during sleep to distribute body pressure, regulate body temperature, and promote blood circulation.
[0008] At this time, pressure may be concentrated in certain areas of the body due to the individual postures that are naturally adopted, and people unconsciously toss and turn to improve the discomfort in those areas where pressure is concentrated, and this tossing and turning interferes with deep sleep.
[0009] Recently, medical institutions have been conducting polysomnography tests in which users are asked to attach sensors to their bodies and sleep in an experimental environment to obtain information about their sleeping posture, and the users are observed through multiple cameras. Information is collected and analyzed based on the results of the polysomnography tests. However, there has been a problem that it cannot fundamentally solve the problem of users' deep sleep.
[0010] The present invention has been devised to solve the above-described problem, and the purpose of the present invention is to provide a smart string bed system that analyzes the user's sleeping posture using a body pressure sensor during sleep in a mattress equipped with a 3D string that maintains a predetermined gap even when a predetermined weight is added and provides a more comfortable cushion feeling to the user through air cushioning, and adjusts the air pressure of the 3D string in real time according to the analysis result to induce and maintain a good night's sleep for the user.
[0011] A smart string bed system according to an embodiment of the present invention for achieving the above-described purpose comprises: a 3D string made of a plurality of threads and using a three-dimensional three-dimensional weaving method to evenly distribute different sizes of body pressure applied from the upper body; and a smart controller for controlling hardness by injecting air into the 3D string or exhausting air to the outside.
[0012] In addition, the smart controller is characterized by having an MCU that controls the operation of the hardness adjustment pump, a hardness adjustment pump that is connected to the 3D string and operates under the control of the MCU to inject high pressure air into the 3D string (120), a solenoid valve interposed between the hardness adjustment pump and the 3D string to control the flow of air flowing (backflowing) from the 3D string to the hardness adjustment pump, a pressure sensor branched between the hardness adjustment pump and the 3D string to measure the pressure inside the 3D string and provide the measured pressure to the MCU, and a Wi-Fi-Bluetooth set that supports Wi-Fi and BLE to enable wireless communication with peripheral devices.
[0013] In addition, it further comprises a pressure sensor unit having a pressure sensor that is interposed between the 3D string and the cushion material that constitutes the mattress and senses (measures) the pressure (body pressure) of the human body located on the upper part of the cushion material; and a monitoring server that learns sleeping postures by AI using a plurality of body pressures sent from the body pressure sensor, finds sleeping patterns, determines a hardness level that matches the sleeping posture, and outputs the result to a smart controller.
[0014] In addition, the body pressure sensor is characterized in that it is formed by arranging a plurality of flexible thin film resistance lines in a horizontal and vertical manner on an insulating fabric, and senses body pressure by measuring resistance at the intersection points.
[0015] In addition, the body pressure sensor is sized to sense body pressure from below the shoulder to above the knee of the human body, and is characterized by a plurality of flexible thin film resistance lines that are uniformly intersected horizontally and vertically at regular intervals.
[0016] In addition, the monitoring server is characterized in that it displays a plurality of sensing values displayed as numbers measured by a body pressure sensor in an image in color for easy viewing based on the numbers.
[0017] In addition, the monitoring server converts a list of a plurality of sensing values displayed as numbers sent from a body pressure sensor into an array similar to the array of body pressure sensors, selects a color for each number, and displays the color by changing the saturation according to the number. However, the monitoring server is characterized in that it divides 9 numbers in a 3*3 array into one group, and changes one number among them so that the remaining 8 surrounding numbers change at a certain ratio.
[0018] In addition, the system further comprises a user terminal having a sleep monitoring app installed on the terminal carried by the user, which records and reports the user's own sleep patterns, thereby enabling the user to accurately understand his or her sleep status.
[0019] In addition, it further comprises an air chamber provided in a plurality at the bottom of the mattress and supported together with the mattress within a receiving space formed in the bed frame; a tilting control pump which is respectively connected to the air chamber and the operation of which is controlled by the smart controller;
[0020] And the above air chamber is composed of five and is provided in the front, back, left, right and center of the bottom of the mattress, and the five tilt control pumps are individually controlled by one smart controller.
[0021] According to the solution to the above-described problem, a mattress equipped with a 3D string that maintains a predetermined gap even when a predetermined weight is added and provides a more comfortable cushioning feeling to the user through air cushioning analyzes the user's sleeping posture using a body pressure sensor during sleep, and adjusts the air pressure of the 3D string in real time according to the analysis results to induce and maintain a good night's sleep for the user.

[0029] Figures 12 to 17 are examples of screens output to the user terminal shown in Figure 3.
[0030] Hereinafter, the configuration and operation of an embodiment of the present invention will be described with reference to the attached drawings.
[0031] FIG. 1 is a block diagram of a smart string bed system according to one embodiment of the present invention.
[0032] As illustrated in FIG. 1, a smart string bed system (100) according to one embodiment of the present invention is configured to include a smart controller (110) and a 3D string (120).
[0033] The above 3D string (120) is provided in the mattress (10) constituting the smart string bed as shown in FIG. 4, and is made of, for example, 14 million threads (high-strength, low-shrinkage yarn made of polyester) (122), and has an ideal structure for distributing body pressure by preventing the balloon effect through a three-dimensional three-dimensional weaving method and maintaining a perfect horizontal plane to evenly distribute different sizes of body pressure coming down from the human body.
[0034] That is, each person has a different body shape (curvature), and the greatest strength of the 3D string (120) when the pressure is adjusted is that it can adapt to the curvature of the human body.
[0035] The above 3D string (120) is described in detail in the registered patent No. 10-2302769 previously filed by the applicant of the present invention, so a detailed description thereof is omitted here.
[0036]
[0037] The smart controller (110) adjusts the hardness of the mattress by injecting air into the 3D string (120) or exhausting air to the outside.
[0038] Through this, the softness of the mattress (10) can be changed as desired according to the user's condition and preference.
[0039] The above smart controller (110) is equipped with an MCU (111), a hardness control pump (112), a solenoid valve (113), a pressure sensor (114), and a Wi-Fi-Bluetooth set (115) as shown in FIG. 2.
[0040] The MCU (111) controls the operation of the hardness control pump (112) manually or automatically.
[0041] The above hardness control pump (112) is connected to the 3D string (120) and operates under the control of the MCU (111) to inject air at high pressure into the inside of the 3D string (120).
[0042] At this time, the flow rate is, for example, 12.0 L / min or more.
[0043] The above solenoid valve (113) is interposed between the hardness control pump (112) and the 3D string (120) to control the flow of air flowing (backward) from the 3D string (120) to the hardness control pump (112).
[0044] The pressure sensor (114) is branched between the hardness control pump (112) and the 3D string (120) to measure the pressure inside the 3D string (120) and provide it to the MCU (111).
[0045] The range of pressure measured at this time is, for example, - 3.6 psi (Pound per Square Inch) to 3.6 psi.
[0046]
[0047] The Wi-Fi-Bluetooth set (115) supports Wi-Fi and BLE to enable wireless communication with surrounding devices such as a pressure sensor unit (130), a monitoring server (150), and a user terminal (140) (see FIG. 3).
[0048]
[0049] By configuring a smart string bed system (100) like this, the softness of the mattress can be automatically or manually changed according to the user's condition and preference.
[0050]
[0051] Figure 3 is a block diagram of a smart string bed system according to another embodiment of the present invention.
[0052] As illustrated in FIG. 3, a smart string bed system (100) according to another embodiment of the present invention is configured to further include a body pressure sensor unit (130), a user terminal (140), and a monitoring server (150) in addition to the smart controller (110) and the 3D string (120).
[0053] In addition, an air chamber (30) and a tilting control pump (160) may be additionally provided.
[0054] The above body pressure sensor unit (130) is equipped with a body pressure sensor (130a), an MCU (131), and a Wi-Fi-Bluetooth set (135) as shown in FIG. 5.
[0055] The above body pressure sensor (130a) is interposed between the 3D string (130) and the cushioning material (24), i.e., between the upper part of the 3D string (130) and the lower part of the cushioning material (24), as shown in FIG. 4, and senses (measures) the pressure (body pressure) of the human body located thereon.
[0056] At this time, if the body pressure sensor (130a) is located on the upper part of the cushion material (24), it may have durability problems because it comes into direct contact with the human body, and the pressure measurement may not be accurate because the cushion material (24) absorbs the primary pressure, but in the case of the present invention, if it is located on the lower part of the cushion material (24), even if the same person lies down, the value received by the body pressure sensor (130a) changes when the pressure changes, and the sensing value changes.
[0057] Based on this, it is possible to adjust the hardness optimized for the human body, and even for the same person, the sensing value can be changed by adjusting the cushion material (130a).
[0058] The above body pressure sensor (130a) is formed by arranging a plurality of flexible thin film resistance lines (134a), i.e., conductive threads, in a horizontal and vertical manner on an insulating fabric (132a), and senses body pressure by measuring the resistance at the intersection.
[0059] At this time, it is desirable to uniformly arrange the conductive thin film resistance wire (134a) at regular intervals to enable automation, thereby improving productivity and facilitating production.
[0060] In addition, if the above pressure sensor (130a) is manufactured to be approximately the same size as the mattress (10), the cost is high at approximately 7 to 8 million won.
[0061] However, when measuring body pressure, the head is different for each pillow anyway, so the head part is excluded, and the actual body pressure coming from the leg part is only 10% to 20% of the human body, so in the present invention, a body pressure sensor (130a) is provided to sense the body pressure from below the shoulder to above the knee, which is the remaining 80%, excluding this, so that the sleeping posture can be known.
[0062] That is, since the present invention enables the sleep posture to be known through the body pressure sensor (130a), the entire body pressure of the person is first measured, and then the body pressure area to be practically focused on is designated so that the body pressure can be sensed by the body pressure sensor (130a) for the area excluding the head area and the leg area below the knees.
[0063] Considering this, the body pressure sensor according to the embodiment of the present invention has, for example, a size of 800 * 1300 (mm) and a sensing point (intersection) of 30 horizontal X 18 vertical, which is 540.
[0064] At this time, the pressure range is 0 to 2.99 psi (Pound per Square Inch), but is not limited thereto.
[0065] The above Wi-Fi-Bluetooth set (135) supports Wi-Fi and BLE to enable wireless communication with a smart controller (110), which is a peripheral device.
[0066] The above-mentioned body pressure sensor unit (130) senses the body pressure from below the shoulder to above the knee at regular intervals during sleep and outputs it to the smart controller (110).
[0067]
[0068] The monitoring server (150) applies an internal AI algorithm, a CNN (Convolutional neural network) algorithm, to analyze the sleeping environment during sleep and learn each individual's sleeping pattern to provide comfortable sleeping conditions to the user.
[0069] To explain this in more detail, first, a person lies down directly on a body pressure sensor (130a) and the person's posture is measured, such as whether he or she is lying upright or on the right side, and then about 20,000 to 30,000 pieces of measured data are accumulated to create a learning model through an AI algorithm on a monitoring server (150).
[0070] When accumulating the above measurement data, rather than accumulating it for just one person, the measurement data must be transformed, so the measurement data is accumulated while lying down straight, but when learning, it is learned so that predictions such as slightly increasing or decreasing the size or turning left and right are possible.
[0071] By learning and applying it in a predictable way like this, the basic data is 20,000 to 30,000 pieces, but in reality, it can create over 100,000 pieces of data.
[0072] Through this, a learning model is implemented in the monitoring server (150), and when the sensing value of the body pressure sensor (130a) is input to the monitoring server (150), the monitoring server (150) determines whether the lying posture is frontal or sideways, etc., based on the sensing value for the current lying state through the learning model.
[0073] The above monitoring server (150) determines the hardness suitable for the sleeping position and transmits it to the smart controller (110).
[0074]
[0075] Meanwhile, the sensing value measured by the above body pressure sensor (130a) is a numerical value, and the monitoring server (150) displays this number as a color image for easy viewing by the user. The closer it is to yellow when viewed by a person, the higher the body pressure is, and the closer it is to blue, the lower the pressure is.
[0076] For example, when a person lies down straight, the shoulder and hip areas are pressed down a lot, as shown in Figure 16, and those areas are displayed in yellow and red.
[0077] This imaging process will be further explained with reference to FIGS. 7 to 11. As shown in FIG. 7, for example, 540 sensing values from a body pressure sensor (130a) are output as numeric values to a monitoring server (150).
[0078] The above monitoring server (150) converts the numerical sequence into an 18*30 array like the array of pressure sensors (130a) as shown in FIG. 8.
[0079] After selecting a color for each number, the color is expressed by changing the saturation according to the number. However, as in Fig. 9, 9 numbers in a 3*3 array are divided into one group, and the remaining 8 surrounding numbers are set to change at a certain ratio according to the change in one number (12) among them.
[0080] This allows colors to be expressed smoothly in the image.
[0081] Figures 7 to 11 are color images of body pressure obtained through this process.
[0082]
[0083] The user terminal (140) may be a terminal carried by the user, for example, a smartphone with a sleep monitoring app (142) installed.
[0084] Users can accurately determine their sleep status by recording and reporting their sleep patterns through a user terminal (140) that communicates wirelessly with a monitoring server (150).
[0085] For example, as shown in Figure 12, users can check a sleep score that synthesizes dozens of data to easily see their sleep health status at a glance.
[0086] The above sleep score can be calculated by calculating actual sleep time compared to the target time, weighting based on sleep status (light sleep, deep sleep time), score based on sleeping position, time taken to fall asleep, and special events during sleep.
[0087] Additionally, as illustrated in Figure 13, an intuitive report can be displayed according to the flow of sleep from before falling asleep until waking up.
[0088] Additionally, as shown in Figure 14, a detailed sleep report on the previous night's sleep, including posture and depth of sleep by sleep time, can be displayed.
[0089] Additionally, as shown in Figure 15, you can see the changes in body shape and the pros and cons of each sleeping position.
[0090] Additionally, as shown in Figure 16, the user can receive a customized hardness recommendation service based on his or her body type during initial setup.
[0091] And as shown in Fig. 17, the connection status of the current mattress (10) and the smart controller (110), i.e., the connection with the body pressure sensor (130a) and the operation status of the smart controller (110) can be checked.
[0092]
[0093] The air chamber (30) is provided at the bottom of the mattress (10) as shown in Fig. 6, and is composed of, for example, five air chambers, and is provided at the front, back, left, right, and center of the bottom of the mattress (10) and is supported by being accommodated together with the mattress (10) within the accommodation space (172) formed in the bed frame (170).
[0094] Each of the above air chambers (30) is connected to a tilting control pump (160a,…,160n), and the tilting control pump (160a,…,160n) is controlled by a smart controller (110), so that the angle (tilting) of the mattress is adjusted by injecting or exhausting air into or from each air chamber (30).
[0095] To explain this a little more, the sleeping posture of a sleeping person can be known by the body pressure sensor (130a), and the direction of tilting can be determined through this.
[0096] For example, if your sleeping position is on your left side, tilt to the right, if your sleeping position is on your right side, tilt to the left, and if your sleeping position is on your back, tilt downwards.
[0097] In the case of the above tilting, there are five air chambers (30), and the pressure of each of the five air chambers (30) can be checked with an unillustrated pressure sensor, so the tilting angle of the mattress (10) can be controlled.
[0098] At this time, five tilting control pumps (160a,…,160n) are controlled by one smart controller (110), and thereby the five air chambers (30) can be individually controlled by the smart controller (110) to tilt the mattress (10) in various directions.
[0099]
[0100] FIG. 4 is an example diagram of a mattress applied to the smart string bed system of FIG. 3. The mattress (10) is formed by stacking a mattress frame (20), a 3D string (120), a body pressure sensor (130a), a cushioning material (24), and a cover (26) in that order from the bottom to the top.
[0101] In this drawing, two 3D strings (120) and two body pressure sensors (130a) are shown as an example, but one 3D string (120) and one body pressure sensor (130a) may be provided.
[0102] The mattress frame (20) has a receiving portion (22) formed inside, and the 3D string (120), pressure sensor (130a), cushioning material (24), and cover (26) are received in the receiving portion (22).
[0103] The above cushioning material (24) may be made of, for example, a two-layer foam of memory foam and polyurethane (PU).
[0104] The upper cover (26) covering the upper surface of the above cushion material (24) provides a cooling function.
[0105]
[0106] Fig. 6 is an example diagram of a bed applied to the smart string bed system of Fig. 3.
[0107] As shown in Fig. 6, five air chambers (30) are provided at the bottom of the mattress (10), and the air chambers (30) are positioned at the front, back, left, right, and center of the bottom of the mattress (10) and are accommodated and supported together with the mattress (10) within the accommodation space (172) formed in the bed frame (170).
[0108]
[0109] In the configuration of such a smart string bed system (100), for example, hundreds of individual pressure sensors, i.e., body pressure sensors (130a), automatically detect the user's movements and uncomfortable leanings during sleep, measure the pressure of the pressed part of the body, i.e., body pressure, and transmit it to the monitoring server (150) through the smart controller (120).
[0110] The above monitoring server (150) uses AI to learn the user's sleeping posture through these hundreds of body pressures, find the sleeping pattern, and determine the user's firmness accordingly.
[0111] For example, there are four basic sleeping positions: upright, left side, right side, and back, as well as crossed legs, arms over one's head, sitting, and postures that pose a risk of falling.
[0112] In addition, the hardness is adjusted in the direction of lowering the hardness when in a different posture based on the above-mentioned posture.
[0113] Additionally, the four basic postures are identified using the above hundreds of body pressures and the tilting angle is determined.
[0114] The monitoring server (150) continuously outputs a control signal to the smart controller (110) with the determined hardness and tilting angle, and the smart controller (110) controls the operation of the hardness control pump (112) and the tilting control pump (160a,…,160n) according to the control signal, thereby adjusting the hardness of the 3D string (120) and the tilting angle of the mattress (130).
[0115] By repeating these movements while the user sleeps, the condition of the smart string bed is adjusted for optimal sleep, allowing the user to get a good night's sleep.
