Abstract
Description
Technology Field
[0001] The present invention relates to a cushion, and more specifically, to a portable smart cushion equipped with a posture correction function that is portable and can provide information to enable posture correction when seated. Background Technology
[0003] In modern society, computers and laptops have become very commonplace, and the frequency of using multimedia technology that combines audio and video has increased significantly. Consequently, there is a growing trend of working hours spent sitting in chairs for these tasks. As sedentary lifestyles increase, maintaining a correct and balanced posture for extended periods is by no means an easy task, as unconscious postural changes can occur.
[0004] In addition, students in their growth stage often maintain a posture of bending their upper body and head for long periods to study, which poses a risk of causing spinal deformation due to the forward curvature of the cervical spine; drivers or those engaged in driving who drive for long periods may also face serious risks to traffic safety due to drowsy driving; and office workers spend an average of more than 8 hours a day sitting, which can put a great strain on the lower back, especially the spine, due to prolonged sitting.
[0005] If sitting in an incorrect posture persists, it exerts physical effects on other muscles, organs, and bones, leading to conditions such as shoulder pain, neck pain, cervical disc herniation, lumbar disc herniation, lower back pain, forward head posture, and scoliosis.
[0006] Meanwhile, in some countries such as Denmark and the United States, a culture of working while standing is spreading for the sake of spinal health. Although some domestic companies are also partially transitioning to standing work environments, it is reported that the level of implementation and public response are not yet promising.
[0007] Since the spine plays a vital role in transmitting commands from the brain to various organs of the body, abnormal or rigid skeletal conditions can lead not only to primary conditions such as muscle pain, herniated discs, and chronic fatigue, but also to disorders resulting from organ dysfunction, such as poor hematopoietic function, indigestion, and headaches.
[0008] For modern people, the habit of sitting with proper posture is directly linked to health and is therefore very important; consequently, there is a growing trend emphasizing the importance and necessity of sitting with correct posture, and there is a need to develop various devices and systems to correct sitting posture.
[0009] Generally, a cushion is constructed from materials or shaped to gently support the buttocks when sitting on the floor, and is not designed to maintain the physiological curvature of the backbone.
[0010] Therefore, when sitting naturally with a cushion placed on a flat chair and both soles of the feet touching the ground, the pelvis is prone to kyphosis compared to the forward-bending state of the pelvis in a standing position, and in conjunction with this, the coccyx, sacrum, and spine also kyphosis.
[0011] As a result, the spine loses its physiological curvature and becomes rearwardly bent; consequently, the weight of the upper trunk is applied to the coccyx, ischium, lower lumbar vertebrae or intervertebral discs, and the back of the thighs, thereby increasing the burden on the lower back and coccyx.
[0012] In addition, since it is easy to assume a posture where the legs are crossed, the weight applied to the upper body of the trunk around the ischium becomes unbalanced, which may cause deformation of the skeleton.
[0013] Currently, most floor cushions use mats with a certain cushioning, such as sponges, so there is no technology for posture-correcting cushions designed to correct the user's pelvis, lower back, or spine simply by sitting on them. Prior art literature
[0015] Republic of Korea Registered Patent No. 10-1514685 Republic of Korea Registered Patent No. 10-1897524 Republic of Korea Published Patent No. 10-2021-0032046 The problem to be solved
[0016] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a portable smart cushion equipped with a posture correction function that has a portable structure so that it can be placed and sat on anywhere, such as a floor or a chair, and enables posture correction by detecting the posture while sitting and notifying the user. means of solving the problem
[0018] A portable smart cushion equipped with a posture correction function according to the present invention for achieving such purposes comprises a pair of buttock seating portions formed in a recessed shape so that the buttocks on both sides are each seated on the upper surface, a buttock seating portion that supports the buttocks while extending upwardly inclined from the buttock seating portions, and a ventilation portion formed through the buttock seating portions, and a cushion that forms a shape that encloses the entire buttocks of a person. The cushion may be composed of a three-layer structure comprising: a base layer formed at the bottom and in contact with the floor or a chair; a body layer formed on the upper part of the base layer and forming the overall shape of the cushion; and a buttock support layer formed on the upper part of the body layer with a certain thickness and supporting the buttocks of a person.
[0019] Here, the base layer is made of a biodegradable resin, the body layer is made of either memory foam or latex, and the buttock support layer may be made of silicone material.
[0020] At this time, a heating element may be inserted between the body layer and the buttock support layer to provide a heating function.
[0021] In addition, it is preferable that a plurality of load cells for measuring load are embedded inside the above-mentioned buttock support layer, and that a correction control unit is provided that receives each load measured by the load cells, compares it with a set value to determine the spinal condition and posture, and outputs a correction signal.
[0022] Here, the calibration control unit may include: a load pattern storage module that receives load data detected by the load pattern detection module, links it with time information, and stores it in an allocated area; a load pattern detection module that detects the distribution pattern of the load applied to the buttocks from the load data stored in the load pattern storage module; an analysis judgment module that determines the posture by comparing and analyzing the load pattern detected by the load pattern detection module with a standard load pattern; and a wireless transmission module that notifies the user's mobile device (4000) of the information determined by the analysis judgment module.
[0023] Meanwhile, it is preferable that the above-mentioned buttocks seating portion be formed with a downward slope such that the thigh of the seated person slopes forward by 10 to 20˚. Effects of the invention
[0025] According to the present invention described above, the following effects are achieved.
[0026] First, it is portable and features a structure that adheres closely to the user's buttocks, providing a stable and comfortable seating experience that does not cause fatigue even during prolonged use.
[0027] Second, it is eco-friendly because it contains biodegradable resin.
[0028] Third, a posture correction service can be provided by detecting the user's posture and providing information to maintain the correct posture. Brief explanation of the drawing

[0031] In the following, embodiments of the present invention are provided for a more accessible understanding of the present invention and do not limit the scope of the present invention. That is, the following embodiments are provided to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.
[0032] Furthermore, the terms used herein are for describing embodiments and are not intended to limit the invention. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As used herein, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components in addition to the components mentioned.
[0033] Furthermore, unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning that is commonly understood by those skilled in the art to which the present invention pertains. Also, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.
[0034] In addition, when describing the present invention, if it is determined that a detailed description of related prior art could unnecessarily obscure the gist of the present invention, such detailed description may be omitted.
[0036] A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.
[0037] The present invention relates to a cushion placed on a floor or chair for sitting, and more specifically, to a smart cushion having a structure that allows a user to sit stably and comfortably for a long time, and including a function to correct posture and the spine.
[0038] Before describing the present invention, I would like to briefly explain the terms 'buttocks' and 'hips'.
[0039] You can verify this by looking it up in the 'Standard Korean Dictionary,' where 'eongdeongi' is defined as the upper part of the buttocks and 'gungdungi' as the lower part of the buttocks. Here, 'buttocks' can be seen as a general term for the fleshy area between the waist and the thighs, and it is also referred to as the 'dungbu.'
[0041] FIG. 1 is a perspective view showing a portable smart cushion equipped with a posture correction function according to one embodiment of the present invention.
[0042] Referring to the illustration, the overall structure of the present invention may have a structure having a certain thickness to support the entire buttocks of a person, and having a buttock seating portion (10), a buttock seating portion (20), and a ventilation portion (30) formed on the upper surface.
[0043] First, the buttocks seating portion (10) is formed as a sunken or concave portion where both sides of a person's buttocks are directly seated. And a pair is formed at a certain distance apart so that they are completely distinguishable.
[0044] And the buttocks support portion (20) is formed to extend upwardly from the buttocks support portion (10) toward the person's waist. The buttocks support portion (20) supports the person's buttocks while closely adhering to them.
[0045] Additionally, the ventilation part (30) is formed in the shape of a hole that penetrates vertically between the buttocks seating part (10), thereby supplying air to the buttocks of a seated person to maintain comfort while preventing direct contact with a user with anal diseases such as hemorrhoids. While a single ventilation part (30) may be formed, it may also be a structure in which one or more are formed in a row.
[0046] Preferably, a wing portion (40) may be further formed that extends upward to the outside of the buttock seating portion (20) and wraps around both sides of the buttocks.
[0047] Accordingly, the above buttocks seating portion (10), buttocks seating portion (20), and wing portion (40) have a structure that wraps around the entire buttocks of the person sitting, so that a sense of stability and comfort can be felt when sitting.
[0049] The internal structure of the present invention having such an external structure will be described in detail. FIG. 2 is a cross-sectional view showing the internal structure of the present invention illustrated in FIG. 1.
[0050] Referring to the illustration, the present invention may be composed of a three-layer structure of different materials.
[0051] Specifically, it may be composed of a base layer (100) at the bottom, a body layer (200) in the middle, and a buttock support layer (300) at the top.
[0052] The above base layer (100) is a layer that comes into direct contact with a floor or a chair and may have a structure that has a certain thickness and strength.
[0053] The above base layer (100) may be made of synthetic resin, but an eco-friendly biodegradable resin may be used.
[0054] For example, Poly Lactic Acid (PLA) resin can be used. PLA resin is a biodegradable resin and a thermoplastic polyester of lactide or lactic acid; it can be manufactured by polymerizing lactic acid produced by fermenting starch extracted from corn, potatoes, etc. Since the aforementioned corn, potatoes, etc. are renewable plant resources, PLA resin obtained from them can effectively address the problem caused by the depletion of petroleum resources. Furthermore, PLA resin has eco-friendly characteristics, such as significantly lower emissions of environmentally harmful substances like CO2 during use or disposal compared to petroleum-based materials like polyvinyl chloride (PVC), and it can easily decompose in the natural environment upon disposal. However, PLA resin has poor cold resistance, is prone to cracking at temperatures below 0°C, and has low tensile strength. Therefore, the outer surface of the base layer can be surrounded by silicone-acrylic rubber. At this time, silicone-acrylic rubber is available from METABLENTM S-2006, Mitsubishi Rayon Co, Ltd.
[0055] Preferably, a non-slip member (400) may be attached to the lower surface of the base layer (100) to prevent slipping with the contact surface.
[0056] And the body layer (200) can be formed in a block shape to form the overall shape of the cushion by being laminated on top of the base layer (100).
[0057] The above body layer (200) may be made of a material such as memory foam or latex.
[0058] Additionally, a buttock support layer (300) that supports the user's buttocks while in direct contact with them is laminated on the upper part of the body layer (200). The buttock support layer (300) may be made of silicone material.
[0060] In the present invention, a heating element (1000) may be inserted between the body layer (200) and the buttock support layer (300) to provide a heating function. At this time, the heating element (1000) may be a heating wire or a carbon fiber.
[0061] In addition, the buttock support layer (300) can be implemented with a silicone material so that heat generated from the heating element (1000) is well conducted. Specifically, it includes a first polysiloxane and a thermally conductive filler having a thermal conductivity greater than or equal to a predetermined value. Here, the first polysiloxane is a compound in which silicon atoms and oxygen atoms are alternately bonded to form a chain-like structure, and in this embodiment, the first polysiloxane includes vinyl-terminated dimethylpolysiloxane.
[0062] At this time, the thermally conductive filler is a powder-type material mixed to be evenly distributed inside the first polysiloxane, and comprises at least one selected from the group consisting of alumina oxide, boron nitride, aluminum nitride, silicon carbide, aluminum hydroxide, magnesium oxide, graphite, and carbon black.
[0063] The above thermally conductive filler is preferably 1 to 120 μm in size, and it is desirable to use a mixture of particles ranging from small to large to improve thermal conductivity.
[0064] In this embodiment, the buttock support layer (300) comprises 5 to 30 parts by weight of the vinyl-terminated dimethylpolysiloxane, 65 to 95 parts by weight of the thermally conductive filler, 0.005 to 5 parts by weight of a platinum compound, 0.01 to 5 parts by weight of methylhydrogenpolysiloxane, 0.01 to 5 parts by weight of a pigment, and 0.003 to 2 parts by weight of a retardant.
[0065] The above methylhydrogenpolysiloxane acts as a cross-linker and chain extender, increasing the degree of polymerization of the silicone resin, providing water repellency and excellent flowability, and reducing lump formation.
[0066] If the content of the methylhydrogenpolysiloxane increases compared to the content of the vinyl-terminated dimethylpolysiloxane, the adhesive strength of the buttock support layer (300) decreases, and conversely, if the content of the methylhydrogenpolysiloxane decreases compared to the content of the vinyl-terminated dimethylpolysiloxane, the adhesive strength of the buttock support layer (300) increases.
[0067] To increase the adhesive strength of the above buttock support layer (300), silanol (Si-OH) or methyl-Si may be added.
[0068] The above platinum compound may be a platinum catalyst such as platinum fine powder, platinum black, platinum-containing silica fine powder, platinum-containing activated carbon, chloroplatinic acid, platinum tetrachloride, an alcoholic solution of chloroplatinic acid, a platinum and olefin complex, and a platinum and alkenyl siloxane complex (e.g., divinyl tetramethyl disiloxane) as a catalyst to promote the curing of silicone resin.
[0069] The above-mentioned retarder is a substance used to secure the appropriate curing time required for the entire process, acting as a retarder for controlling the curing speed of the silicone resin. The above-mentioned retarder may be an organic compound having a triple bond or a double bond at its terminal end, examples of which include ethinylcyclohexanol, phenylbutinol, 2-methyl-3-butin-2-ol, 3,5-dimethyl-1-hexin-3-ol, etc.
[0071] As another embodiment of the present invention, a plurality of load cells (2000) for measuring load may be embedded inside the buttock support layer (300).
[0072] Each load measured by the built-in load cell (2000) can be converted into an electrical signal and transmitted to a separate calibration control unit.
[0073] It is preferable that four or more of these load cells (2000) be installed, and they should be arranged in a distributed manner to cover the entire buttocks as much as possible and positioned symmetrically on the left and right sides.
[0074] At this time, it is preferable that the specifications of the load cell (2000) be limited to measuring 1 to 60 kg. This is because if it is less than 1 kg, it is sensitive and may malfunction frequently, and if it is more than 60 kg, not only is the price higher, but the sensor becomes larger, causing the weight of the cushion itself to become heavy and making it difficult to install.
[0075] The above correction control unit (3000) may be provided in the form of a PCB inside the cushion, or preferably in the form of a management server at a distance, and receives a load signal, compares it with a pre-standardized set value to determine the spinal condition and posture, and outputs a correction signal. For example, as illustrated, it may be provided to be installed on the side of the body layer (200).
[0076] Below, the configuration of the calibration control unit (3000) will be explained further with reference to FIG. 3. FIG. 3 is a diagram showing the configuration of the calibration control unit of the present invention.
[0077] The above calibration control unit (3000) can be implemented with a load pattern storage module (3100), a load pattern detection module (3200), an analysis judgment module (3300), and a wireless transmission module (3400).
[0078] First, the load pattern storage module (3100) is connected to the load cell (2000) via wired or wireless connection to receive and store load data detected by each load cell. The load pattern storage module (3100) may be a memory or storage. The memory or storage may be various forms of volatile or non-volatile storage media. For example, the memory may include ROM or RAM.
[0079] At this time, the load data is stored in the allocated area in conjunction with the time information.
[0080] And the load pattern detection module (3200) detects a load pattern from the load data stored in the load pattern storage module (3100). A load pattern is a pattern that allows one to visually see how the load is distributed across the entire buttocks from the load applied to each load cell.
[0081] Additionally, the load pattern detected by the load pattern detection module (3200) is compared and analyzed with a preset standard load pattern to determine the user's posture, and an analysis judgment module (3300) is included.
[0082] The standard load pattern pre-sets the values of each load applied to the load cell according to body weight when the user sits in a correct posture. Therefore, if the error between each detected load pattern and the standard load pattern exceeds a certain level, the analysis judgment module (3300) determines that there is a problem with the user's posture, determines the extent of the error, and notifies the user.
[0083] The results of comparison and analysis by the above analysis judgment module (3300) can be communicated to the user through the above wireless transmission module (3400).
[0084] The above wireless transmission module (3400) is linked with the user's mobile device (4000).
[0085] An app or program is installed on the mobile device (4000), and the results of comparison and analysis by the analysis judgment module (3300) are visually displayed, allowing one to identify their current posture and condition, and additionally, to provide advice and suggestions on actions or changes to be taken to correct the posture.
[0086] It may also be possible to provide additional services by connecting various information for proper posture.
[0088] Meanwhile, in the present invention, it is preferable that the buttocks seating portion be formed with an incline such that the thigh of the seated person slopes downward at an angle of 10 to 20˚ toward the front.
[0089] Specifically, since an inclined portion (50) is formed at an angle of about 10 to 20˚ in front of the above-mentioned buttock seating portion, it is possible to prevent blood circulation from being blocked by the inner side of the seated person's legs.
[0091] Although the present invention has been described above with reference to the drawings according to embodiments thereof, those skilled in the art will be able to make various applications and modifications within the scope of the present invention based on the above content.
