Description

Technical Field

[0001] This invention relates to the field of smart pillow technology, and in particular to a cervical spine detection and fitting pillow and method based on a through-type air column matrix algorithm. Background Technology

[0002] A pillow is a bedding item used to support the head and neck during sleep. Its main function is to maintain the natural physiological curvature of the cervical spine and improve sleep comfort. Pillows have a long history. In ancient times, hard materials such as stone, wood, and porcelain were widely used, and later, soft pillows, mainly made of fabric and buckwheat hulls, gradually developed. Modern pillows are diverse, with filling materials including memory foam, latex, down, and new bio-based materials. Their design emphasizes ergonomic support, breathability, temperature regulation, and antibacterial and anti-mite properties. Depending on sleeping position, there are also subcategories such as side-sleeping pillows and back-sleeping pillows, and smart pillows integrating monitoring and anti-snoring functions have emerged.

[0003] However, existing pillows are mainly designed with ergonomic dimensions based on big data calculations to support the cervical spine curvature. However, the curvature of a universal ergonomic pillow cannot precisely fit everyone. Different individuals have different body sizes, weights, and shapes. Short-term use may not reveal the difference, but long-term use will still cause discomfort to users due to the difference between the curvature of a universal ergonomic pillow and that of an individual. In some cases, it may even directly affect spinal health.

[0004] Therefore, in order to accurately adapt to the cervical curvature of different individuals, there is an urgent need for a smart pillow that can detect the cervical curvature of each user and accurately adapt to it. This pillow can not only help the head and neck musculoskeletal system recover from fatigue, but also adapt to different sleeping positions and significantly improve the user's sleep quality.

[0028] Example 1: like Figure 1-11 The cervical spine detection and fitting pillow based on the through-type air column matrix algorithm includes a detection device 1 and a pillow structure 2. The detection device 1 is the core component for accurate detection of cervical spine curvature. It includes a base 3, which serves as the mounting carrier for the detection device 1. The base 3 has multiple evenly distributed fixed cavities 18 inside, providing installation and movement space for piston column structures 17. The piston column structures 17 are installed in the fixed cavities 18 and are sealed and telescopically fitted with them. The piston column structures 17 can telescopically move along the axial direction of the fixed cavities 18, while ensuring the sealing fit. The fixed cavity 18 is airtight. The piston column structure 17 is fixed in position to the fixed cavity 18 by electromagnetic adsorption. The extension and retraction height of the piston column structure 17 can be flexibly fixed according to the detection requirements. The bottoms of multiple fixed cavities 18 are interconnected to form a unified air passage, which is connected to the pressure stabilizing structure through the air guide tube 8. The pressure stabilizing structure is used to stabilize the air pressure in the fixed cavity 18 to ensure the accuracy of the detection data. The base 3 is provided with a flexible pad 4, which directly contacts the human neck to improve comfort during the detection process and avoid pressure on the neck caused by the hard structure.

[0029] The pillow structure 2 is the core component for achieving cervical spine support. It includes a pillow base 24, which is the basic support structure of the entire pillow structure 2. The pillow base 24 is equipped with a pillow surface 25 and multiple sets of first pressure sensors 26. The pillow surface 25 is in direct contact with the human head and neck to support them. The multiple sets of first pressure sensors 26 are evenly distributed on the lower front side of the pillow surface 25 to detect the pressure distribution of the human neck and shoulders in real time, providing real-time data for subsequent changes in sleeping position (supine or side-lying). The pillow base 24 contains a neck support airbag 27, a head support airbag 28, and posture adjustment mechanisms. The structure features a neck support airbag 27 specifically designed to support the neck, and a head support airbag 28 designed to support the head. The two work together to provide precise, zoned support for the head and neck, accurately adapting to the spinal curvature of different individuals. The neck support airbag 27 and the head support airbag 28 are connected by a pressure balancing pipeline, ensuring that the air pressure between them remains balanced and preventing imbalances in the pressure on the head and neck due to uneven air pressure. This further enhances the comfort and fit of the support. The posture adjustment structure, in conjunction with data from multiple sets of first pressure sensors 26, adjusts the overall height of the pillow structure 2 to accommodate changes in sleeping positions, such as supine or side-lying.

[0030] In the preferred embodiment, the pressure stabilizing structure is used to stabilize the air pressure within the fixed cavity 18, ensuring smooth extension and retraction of the piston column structure 17, thereby guaranteeing the accuracy of cervical curvature detection. It includes an air storage cylinder 7, one end of which is connected to the first air guide tube 8. The air storage cylinder 7 stores a certain amount of gas, serving as a buffer and pressure stabilizer. A control valve 9 is provided on the first air guide tube 8, controlling the opening and closing of the first air guide tube 8 and the gas flow rate, facilitating adjustment of the gas path state according to detection requirements. The other end of the air storage cylinder 7 is equipped with a piston rod 15 that is sealed and extends with it. The piston rod 15 can extend and retract along the axial direction of the air storage cylinder 7, adjusting the gas volume within the air storage cylinder 7 through the extension and retraction movement, thereby regulating the air pressure. The end of the piston rod 15 away from the air storage cylinder 7 is fixedly connected to a limiting connector 14, which restricts the direction of movement of the piston rod 15 to prevent it from deviating. The limiting connector 14 is limited and slidably engaged with the limiting slide groove 20 set on the fixed frame 5. The limiting slide groove 20 provides a sliding track for the limiting connector 14, ensuring that the extension and retraction of the piston rod 15 is along a fixed direction. The fixed frame 5 is fixedly connected to the side wall of the base 3, providing installation support for the various components of the pressure stabilizing structure. The two ends of the fixed frame 5 are fixedly connected to the air storage cylinder 7 and the stepper motor 6, respectively. The stepper motor 6 provides power for the movement of the pressure stabilizing structure. The output end of the stepper motor 6 is equipped with a linkage gear 10. The linkage gear 10 is driven by the synchronous toothed belt 11 and the positioning gear 12. The positioning gear 12 is connected to the fixed frame 5 through the fixed arm 13. The positioning gear 12 plays a positioning and guiding role, ensuring that the transmission of the linkage gear 10 is smooth. The limiting connector 14 is fixedly connected to the synchronous toothed belt 11, thereby driving the piston rod 15 to perform precise extension and retraction movements, realizing precise adjustment of air pressure.

[0031] In a preferred embodiment, the limiting connector 14 is equipped with a first measuring sensor 16. The first measuring sensor 16 is used to detect the extension and retraction displacement of the piston rod 15 and the temperature of the surrounding environment in real time, providing support for air pressure regulation and detection data calibration. The first measuring sensor 16 includes a laser rangefinder and a temperature sensor. The laser rangefinder is used to accurately measure the extension and retraction distance of the piston rod 15, thereby calculating the change in gas volume in the gas storage cylinder 7. The temperature sensor is used to detect the ambient temperature to avoid the influence of temperature changes on air pressure and ensure the accuracy of the detection data.

[0032] In a preferred embodiment, a second measuring sensor 19 is provided at the bottom of the fixed cavity 18. The second measuring sensor 19 is used to detect the extension and retraction displacement of the piston column structure 17 and the temperature inside the fixed cavity 18 in real time, further improving the accuracy of cervical curvature detection. The second measuring sensor 19 includes a laser rangefinder and a temperature sensor. The laser rangefinder is used to accurately measure the length of the piston column structure 17 extending out of the fixed cavity 18, thereby obtaining the height of the protrusions of various parts of the human cervical spine. The temperature sensor is used to detect the temperature inside the fixed cavity 18, providing a basis for the calibration of the detection data.

[0033] In a preferred embodiment, the piston column structure 17 is used to directly contact the human cervical spine to obtain specific data on the cervical curvature. It includes a pin 21 whose bottom engages with the piston in the fixed cavity 18. The pin 21 can flexibly extend and retract along the axial direction of the fixed cavity 18. The top of the pin 21 is provided with a latex head 23, which directly supports the human cervical spine, improving contact comfort and avoiding scratching or pressure on the cervical spine. The pin 21 is made of magnetic material and engages with an electromagnetic brake ring 22 embedded in the inner wall of the fixed cavity 18. When the electromagnetic brake ring 22 is energized, it generates magnetism, forming an electromagnetic attraction force with the magnetic pin 21, thereby fixing the position of the pin 21. The electromagnetic brake ring 22 on the inner wall of the fixed cavity 18 is connected to an energized switch through an electrical wire structure. By controlling the on / off state of the energized switch, the presence or absence of magnetism in the electromagnetic brake ring 22 can be realized, thereby controlling the fixation and movement of the pin 21. This allows for flexible adjustment and calculation of the exhaust volume and the spinal curvature of the test subject according to the testing requirements.

[0034] In a preferred embodiment, the posture adjustment structure is used to adjust the overall posture of the pillow structure 2 so that it can adapt to different sleeping positions of the user, such as supine and side-lying positions, thereby improving fit and comfort. It includes a lifting airbag 29 located at the bottom of the pillow seat 24. The lifting airbag 29 adjusts the height of the pillow seat 24 by inflating and deflating. The lifting airbag 29 is connected to an inflation / deflation pump 31 through a second air duct 30. The inflation / deflation pump 31 provides power for the inflation and deflation of the lifting airbag 29 and can precisely control the inflation amount of the lifting airbag 29 as needed. The lifting airbag 29 is equipped with multiple sets of second pressure sensors 32. The second pressure sensors 32 are used to detect the air pressure inside the lifting airbag 29 and the force on the pillow seat 24 in real time, providing data support for posture adjustment and ensuring that the adjusted posture can accurately adapt to the user's needs.

[0035] In a preferred embodiment, the pressure balancing pipeline is used to achieve air pressure balance between the neck support airbag 27 and the head support airbag 28, ensuring uniform support for the head and neck. It includes a third air guide tube 33 connected to the neck support airbag 27 and the head support airbag 28, providing a channel for gas flow so that the gas inside the neck support airbag 27 and the head support airbag 28 can circulate. One end of the third air guide tube 33 is connected to an inflation / deflation three-way pipe 34, which is used to switch between inflation, deflation, and pressure balancing. One end of the inflation / deflation three-way pipe 34 is connected to an opening / closing three-way pipe 35, which controls the opening and closing of the pressure balancing pipeline. The third end is provided with a one-way inflation port 36, which is used to inflate the neck support airbag 27 and the head support airbag 28 in one direction to prevent gas backflow. The two ends of the opening and closing three-way pipe 35 are respectively connected to the inflation and deflation three-way pipe 34. The third end of the opening and closing three-way pipe 35 is connected to the opening and closing column 38 through the flexible sleeve 37. The flexible sleeve 37 plays a sealing role to prevent gas leakage. The flexible sleeve 37 and the opening and closing column 38 can be inserted and pulled into the third end of the opening and closing three-way pipe 35. By inserting and pulling the opening and closing column 38, the opening and closing of the opening and closing three-way pipe 35 can be controlled, thereby controlling the working state of the pressure balance pipeline. The opening and closing column 38 is provided with a pull head 39, which facilitates the user or equipment to insert and pull the opening and closing column 38.

[0036] In the preferred embodiment, the flexible pad 4 is made of a flexible material, which has good softness and conformity, and can better conform to the curve of the human neck, improve the comfort during the testing process, and reduce neck pressure.

[0037] In the preferred embodiment, both the pillow seat 24 and the pillow surface 25 are made of materials with good support and resilience, which can adaptively conform to the shape of the human head and neck, while providing stable support to prevent the head and neck from being unsupported and further protect cervical spine health.

[0038] Example 2: like Figure 1-11 Meanwhile, the limiting connector 14 on the outer end of the piston rod 15 inside the gas storage cylinder 7 is equipped with a first measuring sensor 16, including a laser sensor and a temperature sensor. The laser sensor can measure how far the gas injector has moved, and combined with the area of ​​the injector barrel, calculate the volume of gas collected when measuring the cervical curve. At the same time, the gas volume is calculated by temperature compensation based on the temperature value.

[0039] Each fixed cavity 18 has a second measuring sensor 19 at its bottom, including a laser sensor and a temperature sensor. By measuring the movement distance of each moving column, the overall cervical spine curvature is fitted, and the volume of the three-dimensional space formed by the fitted curvature and the original plane is calculated and compared with the gas volume collected in the gas storage cylinder 7. The surface fitting is calibrated and compensated using the gas volume. A radial basis function (RBF) with smoothing regularization is used for fitting. The implicit surface is represented by a weighted sum of radial basis functions (such as thin plate splines or multiple quadratic functions). A smoothing term is added to the interpolation, and a smooth surface is obtained by solving a regularized linear system. The regularization parameter λ is continuously adjusted according to the difference between the fitted three-dimensional space and the gas volume collected in the gas storage cylinder 7, so that the volume difference is less than a set threshold.

[0040] Example 3: like Figure 1-11 In the sleep state detection section, the multiple first pressure sensors 26 use five sheet-like pressure sensors, which are evenly distributed at the front of the pillow. In the sleeping position, the shoulder can press the position of the pressure sensor. The specific position of the pressure sensor can be adjusted appropriately according to different people. It should not be too narrow or too wide. The adjustment principle is that the distance between the outermost pressure sensor and the shoulder should not be wider than the shoulder width. When lying on the side, the shoulder cannot press three pressure sensors at the same time.

[0041] When determining whether someone is lying on their side, the pressure values ​​are analyzed based on the data read from the pressure sensors. The variance of the values ​​from the five pressure sensors is calculated. If the variance is greater than the upper limit threshold, it is determined to be lying on their side. If the variance is less than the upper limit threshold but greater than the lower limit threshold, it is determined to be not lying on their side. In the non-lying state, the absolute values ​​of the five sensors are compared. If all five pressure sensor values ​​are less than the set absolute values, it is determined that no one is lying on the pillow. In the non-lying state, the absolute values ​​of the five sensors are compared. If the cumulative change in the absolute values ​​of the five sensors within one minute is less than the set cumulative threshold, it is determined that no one is lying on the pillow, and a heavy object has been placed on it.

[0042] In a non-lateral position, the absolute values ​​of the five sensors are judged. When more than four pressure sensor values ​​are greater than the set absolute value, the position is determined to be supine. Other positions are set as abnormal. In any position, the original values ​​of the pressure sensors will be sent back to the mobile APP for data analysis.

[0043] Example 4: like Figure 1-11 The working principle of this invention is as follows: the core is to accurately acquire the user's cervical curvature data through the detection device 1, process and calibrate the data using a water wave filtering algorithm, and then achieve precise adaptation of the cervical curvature through the pillow structure 2. The specific working process is as follows: Step 1: First, the user places their neck on the flexible pad 4 of the detection device 1. At this time, the piston column structure 17 extends and retracts along the fixed cavity 18 under the pressure of the neck. Step 2: The second measuring sensor 19 detects the telescopic displacement of each piston column structure 17 and the temperature inside the fixed cavity 18 in real time. The first measuring sensor 16 on the limit connector 14 detects the telescopic displacement of the piston rod 15 and the ambient temperature. All detection data are transmitted to the control system, which uses a water wave filtering algorithm to filter the data, eliminate interference factors such as temperature and air pressure, and accurately calculate the actual curvature of the user's cervical spine. Step 3: The control system controls the electromagnetic brake ring 22 to be energized, and the position of the piston column structure 17 is fixed by electromagnetic adsorption, thus locking the cervical curvature detection data. Step 4: Based on the detected cervical curvature data, the control system precisely manufactures the corresponding neck support airbag 27 and head support airbag 28, and then installs them into the pillow seat 24; Step 5: Inflate the neck support airbag 27 and the head support airbag 28 through the inflation / deflation three-way tube 34 and the one-way inflation hole 36, and use the pressure balance pipeline to keep the air pressure of the two balanced until the pillow structure 2 completely conforms to the curvature of the user's cervical spine. Step Six: During use, if the user adjusts their sleeping posture, the first pressure sensor 26 detects a change in pressure distribution, and the control system will restart the adjustment process. By controlling the inflation / deflation pump 31 to inflate or deflate the lifting airbag 29 through the second air duct 30, the height of the pillow seat 24 is adjusted to always keep the cervical spine in its natural physiological curvature.

[0044] The beneficial effects of the present invention are as follows: By using the multiple sets of piston column structures 17 and measuring sensors of the detection device 1, combined with the water wave filtering algorithm, the cervical curvature of different users can be accurately detected, effectively solving the problem that existing universal ergonomic pillows cannot fit individual differences, avoiding neck discomfort and spinal health risks caused by long-term use, and achieving personalized support of "one person, one fit". Pillow structure 2 provides zoned support through neck support airbag 27 and head support airbag 28, and in conjunction with the posture adjustment structure, it can adjust in real time according to the user's cervical curvature and sleeping posture, ensuring that the head and neck are always in a natural physiological curvature, reducing cervical pressure. At the same time, the flexible contact parts enhance the comfort of use, help the head and neck musculoskeletal system recover from fatigue, and significantly improve sleep quality. The pressure stabilizing structure can stabilize the air pressure in the fixed cavity 18. Combined with the dual detection of the first measuring sensor 16 and the second measuring sensor 19, and the water wave filtering algorithm to eliminate interference, the accuracy of the cervical curvature detection data is ensured. The piston column structure 17 fixed by electromagnetic adsorption and the precise and controllable inflation and deflation system make the adjustment process smooth and accurate, and the adaptation response speed fast.

[0045] It can adapt to different sleeping positions such as supine and side-lying. Through the coordinated adjustment of the posture adjustment structure and airbag components, it can adjust in real time according to the user's sleeping position changes to meet different usage needs. The design of the pressure balance pipeline ensures that the airbag support is uniform. At the same time, the plug-in design of the opening and closing column 38 can flexibly switch the air pressure adjustment mode, improving the convenience of use.

[0046] It achieves both accurate detection of cervical curvature and personalized support, requiring no complicated operation, and is suitable for various groups of people, making it widely applicable and valuable for promotion.

10. The method for calculating the cervical spine detection and fitting pillow based on the through-type air column matrix algorithm according to any one of claims 1-9, characterized in that... Includes the following steps: Step 1: First, the user places his neck on the flexible pad (4) of the detection device (1). At this time, the piston column structure (17) extends and retracts along the fixed cavity (18) under the pressure of the neck. Step 2: The second measuring sensor (19) detects the telescopic displacement of each piston column structure (17) and the temperature inside the fixed cavity (18) in real time. The first measuring sensor (16) on the limit connector (14) detects the telescopic displacement of the piston rod (15) and the ambient temperature. All detection data are transmitted to the control system, which uses a water wave filtering algorithm to filter the data, eliminate interference factors such as temperature and air pressure, and accurately calculate the actual curvature of the user's cervical spine. Step 3: The control system controls the electromagnetic brake ring (22) to be energized, and the position of the piston column structure (17) is fixed by electromagnetic adsorption, thus locking the cervical curvature detection data; Step 4: The control system precisely manufactures the corresponding neck support airbag (27) and head support airbag (28) based on the detected cervical curvature data, and then installs them into the pillow seat (24); Step 5: Inflate the neck support airbag (27) and head support airbag (28) through the inflation / deflation three-way tube (34) and one-way inflation hole (36), and use the pressure balance pipeline to keep the air pressure of the two in balance until the pillow structure (2) completely conforms to the curvature of the user's cervical spine. Step 6: During use, if the user adjusts their sleeping posture, the first pressure sensor (26) detects a change in pressure distribution. The control system will restart the adjustment process and control the inflation and deflation pump (31) to inflate and deflate the lifting airbag (29) through the second air duct (30) to adjust the height of the pillow seat (24) and always keep the cervical spine in its natural physiological curvature.
