Description

Technical Field

[0001] The present invention relates to the technical field of intelligent health care devices, and particularly to an adjustable-height pillow based on deep learning and multi-modal sensor fusion. Background Art

[0002] With the changes in modern lifestyle and the widespread use of electronic devices, the incidence of cervical diseases has been increasing year by year. In particular, people who work with their heads down or use electronic devices for a long time are more likely to have cervical problems. At the same time, during the postoperative rehabilitation period of cervical disease patients, the requirements for the support and fixation of the head and neck are more stringent to ensure the postoperative recovery effect and avoid secondary injuries caused by improper postures. However, existing pillow products still have many deficiencies in postoperative rehabilitation support and are difficult to meet the needs of different individuals.

[0003] Traditional postoperative rehabilitation pillows usually adopt a fixed height and angle design, without fully considering the differences in cervical curvature, shoulder width, and body shape of different patients. This fixed structure may cause some users to not obtain sufficient support during use, and even aggravate neck discomfort. For example, when lying on the side, users with a relatively narrow or wide shoulder width may have a tilted head and neck due to the mismatch of the pillow height, which will affect postoperative recovery. In addition, when lying on the back, if the pillow height does not meet the ergonomic requirements, it may cause the cervical spine to be in an abnormal forward flexion or excessive backward extension state, affecting normal breathing and sleep quality.

[0004] In recent years, with the development of intelligent adjustment technology, personalized health devices have gradually become a research hotspot. However, in the field of cervical postoperative rehabilitation pillows, precise adjustment solutions for individual differences are still relatively lacking. Most existing adjustable pillows rely on mechanical manual adjustment, which is cumbersome to operate and difficult to achieve fine adjustment, and it is difficult to meet the high requirements of cervical postoperative patients for stability and comfort. In addition, although some products provide adjustment methods such as adding or reducing fillers or replacing support components, they still cannot automatically adapt to user needs in different sleeping postures, limiting their practicality.

[0005] Therefore, there is an urgent need for an intelligent rehabilitation pillow that can adjust the height and angle according to the personalized needs of cervical postoperative patients, which can provide dynamic support according to the body shape characteristics and sleeping postures of different individuals while ensuring the stability of the cervical spine, so that the head, neck, shoulders, and torso of the patient are on the same horizontal line when lying on the back or side. This product should combine a precise height adjustment mechanism, an intelligent sensing system, and ergonomic design to improve the postoperative rehabilitation effect and enhance the comfort and user experience of users. Summary of the Invention

[0006] The object of the present invention is to provide an intelligent massage neck pillow suitable for patients after cervical spine surgery. This pillow can accurately adjust the height and angle according to the individual differences of users, ensuring that the head, neck, shoulders and torso are on the same horizontal line, thereby improving the stability and comfort of postoperative rehabilitation. By integrating an intelligent sensing system, an adjustable support mechanism and a multi-modal data fusion algorithm, it realizes real-time monitoring and dynamic adjustment of the user's posture, and solves the problems of the existing cervical spine rehabilitation pillows in terms of fixed height, mismatched angles, unstable support, etc. The present invention adopts intelligent adjustment technology, enabling the pillow body to be adjusted individually according to the shoulder width, cervical spine curve and sleeping posture requirements of different users. The power unit, under the control of the intelligent unit and the sensor group, can sense the pressure distribution, posture changes and physiological signals of the user's head and neck, and dynamically adjust the height, angle and massage intensity of the pillow body, ensuring that patients of different body types can obtain reasonable support and a comfortable sleeping experience when lying on their backs or sides.

[0012] The first support body and the second support body are respectively fixedly connected to the inflatable massage soft pad. The inflatable massage soft pad is divided into two parts and is glued to the first support body and the second support body respectively; the second support body forms an X-shaped fitting structure around the first support body.

[0013] The pillow base is provided with an occipital bone groove and a cervical and dorsal groove. The bottom plate is provided with rollers; the roller assembly restricts the sliding angle of the rollers. The intelligent unit adopts deep learning and multi-modal data fusion algorithms; the sensor group includes: a pressure sensor, specifically a MEMS sensor, an axis inertial measurement unit, a temperature and humidity sensor, a strain gauge sensor, and a bio-signal sensor.

[0014] The intelligent unit uses long short-term memory networks and gated recurrent units for time series prediction, and adopts a CNN+Transformer combined structure, specifically including: extracting the user's cervical curve features through CNN; modeling the changes in the user's different sleep postures through the Transformer self-attention mechanism. The sensor group performs data transmission through the CAN bus and I 2 C / SPI hybrid protocol, where: low-speed data such as pressure, temperature and humidity are transmitted through I 2 C; high-speed data such as IMU and strain gauges are transmitted through SPI; the CAN bus is responsible for multi-sensor synchronization.

[0015] It also includes an elastic member and a pillow bottom; the elastic member is arranged between the pillow body and the bottom plate. The pillow bottom internally contains a vibration massage module, and the vibration massage module is connected to the intelligent unit using the CAN bus and performs adaptive adjustment based on the user posture data of the sensor group.

[0016] Through the above technical solutions, the present invention is not only applicable to the rehabilitation care of patients after cervical spine surgery, but also applicable to the daily use of long-term desk workers, mobile phone addicts and other people with cervical spine problems. Its intelligent adjustment system can effectively reduce neck fatigue, improve the convenience of cervical spine health management, and thus improve the overall sleep quality and health level of users.

[0017] Furthermore, the present invention conducts multi-level optimization on the overall structure, intelligent adjustment system and user adaptability of the massage neck pillow according to the special needs of patients after cervical spine surgery, so as to ensure that it provides stable, comfortable and ergonomic support effects during the postoperative rehabilitation process.

[0018] To improve the adaptability of the pillow body, the present invention adopts a support mechanism with adjustable height and angle, enabling the pillow to be precisely adjusted according to the individual characteristics of users. The power unit and the pushing arm structure are integrated inside the pillow body, and the lifting and tilting angle of the pillow body are controlled by the intelligent unit to adapt to the cervical curves of different users.

[0023] Through the above optimized design, the intelligent massage neck pillow of the present invention can effectively adapt to the personalized needs of different users, provide more precise head and neck support and rehabilitation assistance functions, and at the same time ensure the comfort and stability during use, meeting the rehabilitation and daily health management needs of patients after cervical spine surgery and people with long-term cervical spine fatigue.

As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] Figure 1 It is the control system flowchart of the intelligent massage neck pillow of the present invention. Figure 2 It is the overall function framework schematic diagram of the intelligent massage neck pillow of the present invention. Refer to Figure 1 、 Figure 2 In the control system of the intelligent massage pillow, the multi-sensor data fusion algorithm is one of the core technologies. Since the system includes multiple different types of sensors (such as pressure, IMU, temperature and humidity, strain gauge, biological signal, etc.). Data fusion mainly involves time series prediction, spatial information modeling, and personalized optimization, and a method combining deep learning and traditional signal processing is used to process these data. The steps are as follows:

[0038] S01: Low-level signal preprocessing

[0039] (1) Low-level signal preprocessing: The sampling frequencies of different sensors are different. Pressure sensor: 10Hz (detecting head pressure changes); IMU accelerometer: 100Hz (detecting minute neck movements); temperature and humidity sensor: 1Hz (monitoring environmental parameters); biological signal sensor (ECG / PPG): 200Hz (used for detecting heart rate changes). Since these data have different frequencies, time alignment must be performed. The interpolation method and sliding window processing are used to input all data into the deep learning model at the same time scale.

[0040] (2) Filtering processing. To reduce sensor noise, the following filtering strategies are adopted: Pressure sensor / IMU: Kalman filtering (EKF / UKF) for dynamic denoising; temperature and humidity data: mean filtering to reduce the influence of mutation values; heart rate ECG signal: band-pass filtering (0.5Hz - 4Hz) to remove power frequency noise.

[0041] S02: Temporal information modeling

[0042] (1) Time series prediction using LSTM / GRU: Since pressure, acceleration, and attitude data are all time series signals, we use Long Short-Term Memory (LSTM) or Gated Recurrent Unit (GRU) for modeling: Input: Multi-sensor time series data within the past N seconds; Network structure: 2 - 3 layers of LSTM / GRU stacked, with a hidden layer dimension of 128 - 256; Output: Predict the optimal support angle of the pillow for the next 1 - 5 seconds.

[0043] (2) Prediction targets: LSTM is mainly used for predicting: the changing trend of the user's neck posture; whether the user enters a deep relaxation state (based on pressure signals); whether an angle adjustment is needed (based on ECG / PPG monitoring of the pressure level)

[0044] Formula:

[0045] ht = f(W x x t + W h h t-1 + b)

[0046] Where: h t is the current hidden state; x t is the current input sensor data; W x , W h are weight matrices; f is the activation function.

[0047] S03: Spatial information modeling

[0048] (1) CNN + Transformer

[0049] To extract features from the static cervical spine morphology, we use CNN (Convolutional Neural Network) +

[0050] Transformer structure:

[0051] CNN part: Used to extract local features of neck pressure distribution and massage intensity; Transformer part: Used to model the changing trend of the user's posture and perform global information modeling. Network structure: CNN extracts cervical spine curve features: Convolution kernel size: 3×3; 4 layers of convolution, ReLU activation; The result is sent to the Transformer layer;

[0052] Transformer calculates global relationships: The self-attention mechanism calculates the correlation between pressure and posture changes in different regions; Multi-Head Attention processes multi-modal information (posture + pressure + heart rate).

[0053] S04: Adaptive parameter optimization (Bayesian optimization)

[0054] The massage intensity, angle, and support force need to be personalized and adapted, and Bayesian optimization is used to automatically adjust the parameters.

[0055] S05: Optimize the massage path using reinforcement learning: RL adopts PPO (Proximal Policy Optimization). If reinforcement learning is used to adjust the massage path, Proximal Policy Optimization (PPO) is adopted, and the reward function (R):

[0056]

[0057] Objective optimization:

[0058]

[0059] Among them, π is the policy and γ is the discount factor.

[0060] S06: Path planning: If path optimization is involved, the A* or Dijkstra algorithm is adopted.

[0061] S07: Result output

[0062] Finally, the output of the data fusion model is: real-time adjustment of the adaptive adjustment of the pillow body angle (based on cervical spine pressure), personalized relaxation strategy (based on bio-signal analysis), and intelligent adaptation to different users (based on transfer learning).

[0063] Refer to Figures 3 - 6 , this intelligent massage neck pillow includes a pillow base 1, an inclined groove 2, a pillow body 6, a power unit 62, an intelligent unit 7, and a sensor group 8. The top of the pillow base 1 is provided with an occipital bone groove 3 and a neck and back groove 4 for fitting the user's head and neck to improve support and comfort. The pillow body 6 is installed in the inclined groove 2 and can be dynamically adjusted to adapt to the neck shapes of different users.

[0064] After the user lies down, the occipital bone groove 3 and the neck and back groove 4 of the pillow base 1 provide basic fixed support, positioning the user's head in the central area of the pillow body 6. The sensor group 8 includes MEMS pressure sensors, IMU inertial measurement units, bio-signal sensors, etc., and starts to monitor information such as the user's head and neck posture, shoulder height, and neck pressure distribution, and transmits the data to the intelligent unit 7 for calculation.

[0065] The pillow body 6 is composed of a first support body 63 and a second support body 65, which adopt an X-shaped interlocking structure and are connected by a central hinge 611, so that they can rotate around the central axis to change the angle of the pillow body 6. The motor 621 of the power unit 62 drives the reducer 622, which reduces the speed and increases the torque, and transmits the power to the main driving gear 623. The main driving gear 623 drives the passive circular arc toothed disc 624 to rotate, and the rotating shaft portion 625 of the passive circular arc toothed disc 624 is fixed on the fixed seat 626 of the bottom plate 61, and its rotation will change the angle of the push arm 627. The front end of the push arm 627 is provided with a slide groove 5, which is embedded in the first guide rail 69, so that the push arm 627 can move smoothly within the limited track to prevent skewing or shaking. The movement of the push arm 627 pushes the first support body 63, so that the X-shaped structure is expanded or contracted, thereby changing the tilt angle of the pillow body. This adjustment changes the relative height of the head, neck and shoulders, ensuring that the head, neck and shoulders are on the same level and improving the support effect.

[0066] The sensor group 8 continuously monitors the user's head and neck pressure distribution and posture changes, and transmits the data to the intelligent unit 7. The intelligent unit 7 uses the LSTM / GRU time series prediction algorithm to calculate the user's cervical spine posture change trend and predict its optimal support angle. When the sensor detects that the cervical spine is unevenly stressed or the user's sleeping posture changes, the intelligent unit 7 will recalculate the appropriate pillow angle and adjust it through the power unit 62. When the push arm 627 pushes upward, the first support body 63 and the second support body 65 unfold, raising the front of the pillow body 6 to increase the cervical support force; when the push arm 627 contracts downward, the first support body 63 and the second support body 65 contract, making the pillow body 6 horizontal and reducing cervical pressure.

[0067] The multi-point airbags of the inflatable massage cushion 64 can be automatically inflated and deflated according to the user's sleeping position and the stress on the neck. The intelligent unit 7 detects the stress on the left and right sides of the neck through the pressure sensor and adjusts the inflation amount of the cushion 64 to make the support more uniform. When the sensor detects that the pressure on one side is higher, the intelligent unit 7 controls the cushion 64 to be properly inflated on that side to increase the support strength and return the neck to the correct position; when the pressure is lower, the cushion 64 is properly deflated to reduce uneven pressure. In addition, the inflatable massage cushion 64 can be rhythmically inflated and deflated in the cervical spine area to simulate hand massage, promote blood circulation, relieve neck muscle fatigue, and work in conjunction with the vibration massage module at the bottom of the pillow 10 to make the massage mode more accurate.

[0068] In terms of stability control, the roller assembly 628 restricts the movement trajectory of the push arm 627 to ensure that the adjustment angle of the push arm is within a reasonable range, preventing excessive adjustment from causing the pillow body to tilt too much. The first wear-resistant piece 610 is installed on the first guide rail 69 to reduce the friction during the sliding of the push arm 627 and improve the smoothness and accuracy of adjustment. The intelligent unit 7 continuously calculates the optimal angle of the user's cervical vertebra through real-time feedback control and adjusts the operating parameters of the power unit 62 to ensure that the adjustment of the pillow body 6 does not deviate from the preset trajectory.

[0069] Figure 3 This is an exploded structural schematic diagram of the intelligent massage neck pillow of the present invention. The outside of the pillow body 6 is wrapped by an inflatable massage soft pad 64, and a push arm 627, a first guide rail 69 and a roller assembly 628 are installed inside. The roller assembly 628 is provided on the bottom plate 61, and this assembly is used to restrict the sliding angle of the roller to ensure the stable movement of the pillow body 6 in the inclined groove 2 and improve the massage effect.

[0070] Figure 4 The internal structure of the power unit 62 of the present invention is shown, which includes a motor 621, a speed reducer 622 and a gear transmission mechanism. The motor 621 drives the speed reducer 622 to stably output power to the push arm 627, thereby controlling the movement of the pillow body 6.

[0071] Figure 5 This is a schematic diagram of the mechanical transmission structure of the present invention. A central hinge 611 is provided at the junction of the first support body 63 and the second support body 65, enabling the two to form an X-shaped fitting structure around the hinge. The power unit 62 pushes the push arm 627 to adjust the pillow body 6 according to different massage modes to match the different force requirements of the user's neck.

[0072] Figure 6 This is a partial enlarged schematic diagram of the power transmission system. The chute 5 of the push arm 627 is embedded in the first guide rail 69, and the movement of the chute 5 is restricted by the first wear-resistant piece 610 to ensure that the push arm 627 can reduce friction when transmitting power, improving the transmission accuracy and durability.

[0073] The present invention realizes personalized massage adjustment through intelligent algorithms and multi-sensor fusion technology. The intelligent unit 7 dynamically adjusts the shape of the inflatable massage soft pad 64 based on the user's posture, pressure and physiological signals, and optimizes the control parameters of the power unit 62 to provide more ergonomic support and massage functions. Through the above technical solutions, the present invention significantly improves the applicability, comfort and intelligence level of the massage neck pillow, meeting the needs of different users for cervical spine health management.
