Description

Technical Field

[0001] This invention relates to the field of smart homes, and more particularly to a brainwave-assisted sleep mattress system and method. Background Technology

[0002] Sleep is essential for human survival, and sleep problems are a hot topic of concern. With societal development, pressure from work or family life, or various other reasons, many people experience sleep quality issues. Common sleep problems include increased time spent falling asleep, difficulty falling asleep quickly, reduced sleep duration, frequent dreams, and poor sleep quality. These sleep problems cause physical discomfort, fatigue, and an inability to maintain a good mental state for work and study. This can lead to difficulty concentrating, and in certain professions, insufficient sleep can potentially cause serious problems and accidents.

[0003] Currently, sleep monitoring and sleep aid products have relatively limited functions. This invention designs a sleep-aid mattress system based on electroencephalogram (EEG). This system has dual functions of sleep monitoring and sleep aid, analyzing and processing the collected sleep signals, monitoring the sleep-aid effect, and assessing sleep quality, which is of great significance for improving sleep problems. Summary of the Invention

[0004] Regarding the aforementioned technologies, the inventors believe they have the following drawbacks: Currently available sleep aid products have relatively limited functionality, thus limiting their practicality. To overcome these shortcomings...

[0005] One of the objectives of this invention is achieved through the following technical solution:

[0006] A brainwave-assisted sleep mattress system includes a smart mattress, a data transmission module, and a smart controller; the smart mattress is connected to the smart controller via the data transmission module.

[0007] The smart mattress includes a sleep monitoring module and a sleep aid module. The sleep monitoring module includes a heart rate detection submodule, a breathing detection submodule, a pressure detection submodule, and a sound source detection submodule.

[0008] The sleep monitoring module transmits the collected signals to the smart controller through the data transmission module. The smart controller analyzes and determines whether the user is in deep sleep, REM sleep, light sleep, or insomnia. The sleep aid module then adjusts and improves the user's current sleep state.

[0009] Furthermore, the sleep aid module includes a brainwave sleep aid submodule, a temperature regulation submodule, an angle adjustment submodule, and a vibration massage submodule. The brainwave sleep aid submodule is used to emit brainwaves to help the user fall asleep; the temperature regulation submodule is used to adjust the surface temperature of the smart mattress to create a comfortable contact temperature to improve the user's sleep; the angle adjustment submodule adjusts the smart mattress to a comfortable angle for the user or a preset angle; and the vibration massage submodule is used to massage the user to help them fall asleep or relax.

[0010] Furthermore, the brainwave sleep aid submodule emits different combinations of alpha waves, beta waves, k-complex waves, theta waves, and delta waves to aid sleep depending on whether the user is in deep sleep, REM sleep, light sleep, or insomnia.

[0011] Furthermore, the temperature regulation submodule adaptively adjusts the pre-cooling or pre-heating time based on the user's preset working time. It compares the preset temperature with the target temperature on the surface of the smart mattress, automatically selecting the pre-cooling or pre-heating mode. When the smart mattress temperature is higher than the target temperature, the mattress uses the pre-cooling mode; otherwise, it uses the pre-heating mode. Simultaneously, based on the temperature difference, it adaptively adjusts the pre-cooling and pre-heating time so that the completion time is approximately equal to the user's preset working time. The pre-heating time, pre-cooling time, and temperature difference conform to the following relationship:

[0012] t cold = 2.5ΔT + (3 + c)

[0013] t heat =0.027ΔT 3 -0.167ΔT 2 +3.91ΔT+(0.47+c)

[0014] Where t cold Indicates the precooling time, t heat ΔT represents the preheating time, ΔT represents the temperature difference, and c represents the precooling and preheating margin value, where c∈{1~10}.

[0015] Furthermore, the angle adjustment submodule is used to adjust the tilt angle of the head area, back area, and leg area of ​​the smart mattress as they rise and fall.

[0016] Furthermore, the vibration massage submodule includes airbags and a vibration massager, used to massage different parts of the body to varying degrees according to the user's physical condition; the volume change of the airbags can change the shape curve of the mattress surface according to the user's sleeping posture, conforming to and supporting the user's body; the vibration massage submodule adjusts the firmness of the mattress by changing the inflation amount of the airbags to better conform to the user's body, and through the interaction with the vibration massager, it realizes the acupoint massage function, and appropriately adjusts the user's sleeping posture according to the user's physical condition.

[0017] Furthermore, the sleep monitoring module is used to detect and determine the user's current state, which may be any one of deep sleep, REM sleep, light sleep, or insomnia.

[0018] Furthermore, when the sleep monitoring module detects that the user is in any of the following states: deep sleep, REM sleep, light sleep, or insomnia, the user's sleep state is sent to the smart controller via the data transmission module. The smart controller then uses the data transmission module to control the brainwave sleep aid submodule, temperature regulation submodule, angle adjustment submodule, and vibration massage submodule of the smart mattress.

[0019] The second objective of this invention is achieved by the following technical solution:

[0020] A method of using a brainwave-assisted sleep mattress, applied to a brainwave-assisted sleep mattress system as described in one of the objectives of this invention, wherein the method of using the intelligent deep sleep mattress includes:

[0021] Initialization steps: The system initializes by starting the smart mattress through the smart controller;

[0022] Detection steps: The sleep monitoring module detects the user's current state and sends the data to the smart controller to determine whether the user is currently in deep sleep, REM sleep, light sleep, or insomnia.

[0023] Processing steps: Based on the judgment result, the smart controller sends the corresponding control model to the smart mattress through the data transmission module to control the sleep aid module to work and improve the user's current sleep state;

[0024] Adjustment steps: The brainwave sleep aid submodule emits brainwaves of corresponding frequency combinations to the user; the temperature adjustment submodule adjusts the surface temperature of the smart mattress to create a comfortable contact temperature to improve the user's sleep; the angle adjustment submodule adjusts the smart mattress to a comfortable or preset angle for the user; the vibration massage submodule massages the user to aid sleep or relax.

[0025] Furthermore, in the initialization step, the user inputs user information and preset adjustment scheme through the intelligent controller. The intelligent controller then automatically generates a suitable massage strategy for the smart mattress based on the user's sleep and health status, and provides feedback adjustment on massage parameters such as massage position, massage intensity, and massage duration to improve the user's sleep quality and health status. It also evaluates the sleep quality improvement effect of the massage strategy, realizing massage adjustment based on intelligent biofeedback.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] (1) This invention can simultaneously achieve sleep aid and sleep detection through the sleep aid module and the sleep detection module, which solves the problem of single function in existing products. Through the intelligent controller, it automatically generates a suitable massage strategy for the smart mattress according to the user's sleep and health status, and adjusts the massage parameters such as massage position, massage intensity and massage duration to improve the user's sleep quality and health status, and evaluates the sleep quality improvement effect of the massage strategy, thus realizing massage adjustment based on intelligent biofeedback.

[0028] (2) The present invention is equipped with airbags, which replace the traditional pressure column, effectively reducing noise and enabling the smart mattress to change its volume according to the user's own physical condition and change the shape curve of the mattress surface according to the user's sleeping posture, so as to better fit and support the user's body.

[0029] (3) The vibration massage sub-module of the present invention can realize that the vibration massager has the function of acupoint massage. It combines the physiotherapy method of traditional Chinese medicine acupoint massage with the principle of smart home to design a physiotherapy smart mattress, bringing a relaxing and massage physiotherapy method, which can save users time while also enabling them to have a healthy lifestyle.

[0030] (4) By adaptively adjusting the temperature control period, the present invention can quickly reach the user's preset optimal temperature, so that all areas of the human body are in the comfortable temperature range of sleep throughout the entire sleep process and achieve the purpose of energy saving.

[0032] Figure 2 A flowchart illustrating the method of using a brainwave-assisted sleep mattress provided by this invention;

[0033] Figure 3 This is a schematic diagram of the operation of the brainwave sleep aid submodule provided by the present invention. Detailed Implementation

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1

[0036] This invention provides a preferred embodiment of a brainwave-assisted sleep mattress system, such as... Figure 1 As shown, the device includes a smart mattress, a data transmission module, and a smart controller; the smart mattress is connected to the smart controller via the data transmission module.

[0037] The smart mattress includes a sleep monitoring module and a sleep aid module. The sleep monitoring module includes a heart rate detection submodule, a breathing detection submodule, a pressure detection submodule, and a sound source detection submodule.

[0038] The sleep monitoring module transmits the collected signals to the smart controller through the data transmission module. The smart controller analyzes and determines whether the user is in deep sleep, REM sleep, light sleep, or insomnia. The sleep aid module then adjusts and improves the user's current sleep state.

[0039] Furthermore, the sleep aid module includes a brainwave sleep aid submodule, a temperature regulation submodule, an angle adjustment submodule, and a vibration massage submodule. The brainwave sleep aid submodule is used to emit brainwaves to help the user fall asleep; the temperature regulation submodule is used to adjust the surface temperature of the smart mattress to create a comfortable contact temperature to improve the user's sleep; the angle adjustment submodule adjusts the smart mattress to a comfortable angle for the user or a preset angle; and the vibration massage submodule is used to massage the user to help them fall asleep or relax.

[0040] Furthermore, the brainwave sleep aid submodule emits different combinations of alpha waves, beta waves, k-complex waves, theta waves, and delta waves to aid sleep depending on whether the user is in deep sleep, REM sleep, light sleep, or insomnia.

[0041] like Figure 3 As shown, different brainwave patterns are sent to aid sleep based on the user's sleep stage: when the user is insomniac / awake, alpha and beta waves are sent via the brainwave sleep aid submodule; when the user is in light sleep, k-complex waves, theta waves, and delta waves are sent; when the user is in REM sleep, alpha, beta, and theta waves are sent; and when the user is in deep sleep, delta waves are sent.

[0042] Furthermore, the temperature regulation submodule adaptively adjusts the pre-cooling or pre-heating time based on the user's preset working time. It compares the preset temperature with the target temperature on the surface of the smart mattress, automatically selecting the pre-cooling or pre-heating mode. When the smart mattress temperature is higher than the target temperature, the mattress uses the pre-cooling mode; otherwise, it uses the pre-heating mode. Simultaneously, based on the temperature difference, it adaptively adjusts the pre-cooling and pre-heating time so that the completion time is approximately equal to the user's preset working time. The pre-heating time, pre-cooling time, and temperature difference conform to the following relationship:

[0043] t cold = 2.5ΔT + (3 + c)

[0044] t heat =0.027ΔT 3-0.167ΔT 2 +3.91ΔT+(0.47+c)

[0045] Where t cold Indicates the precooling time, t heat ΔT represents the preheating time, ΔT represents the temperature difference, and c represents the precooling and preheating margin value, where c∈{1~10}.

[0046] By adaptively adjusting for pre-cooling and pre-heating, the smart mattress can quickly reach the target temperature from the moment it comes into contact with the user, achieving energy-saving goals while effectively improving the user experience.

[0047] User feedback indicates that the systems in the torso are more active and have lower temperature requirements; however, the leg area has fewer blood vessels, and some people, such as women and children, tend to have cold feet and require higher temperatures. Furthermore, in the early stages of sleep, slightly lowering the sleep temperature helps users fall asleep quickly; in the middle stages of sleep, the skin surface temperature decreases, reducing the perception of ambient temperature, and slightly raising the sleep temperature can provide beneficial stimulation; in the later stages of sleep, slightly raising the sleep temperature can help wake the user. A longitudinal comparison of suitable temperature control ranges in summer and winter shows that the leg area has the highest temperature control range, followed by the torso area, and the head and neck area has the lowest. A horizontal comparison shows that the temperature control range is relatively low in the early stages of sleep, and relatively high in the middle and later stages. If the skin surface temperature of a given area during a given stage is within the comfortable sleep temperature range, then that temperature control value is considered suitable for that area and stage.

[0048] In one embodiment, the smart mattress of the present invention can also achieve different temperature settings for different areas, realizing expected functions such as zoned (head, waist, legs), time-based temperature control, adaptive adjustment, and user-personalized settings, which can more effectively improve the user's sleep quality.

[0049] Furthermore, the angle adjustment submodule is used to adjust the tilt angle of the head area, back area, and leg area of ​​the smart mattress as they rise and fall.

[0050] This invention allows for customized adjustment of the height (tilt angle) of three areas of the mattress, enabling users to adjust to the most ideal sleeping posture according to their needs. This promotes relaxation and blood flow to the calves, further enhancing physical comfort and promoting relaxation and sleep.

[0051] Furthermore, the vibration massage submodule includes airbags and a vibration massager, used to massage different parts of the body to varying degrees according to the user's physical condition; the volume change of the airbags can change the shape curve of the mattress surface according to the user's sleeping posture, conforming to and supporting the user's body; the vibration massage submodule adjusts the firmness of the mattress by changing the inflation amount of the airbags to better conform to the user's body, and through the interaction with the vibration massager, it realizes the acupoint massage function, and appropriately adjusts the user's sleeping posture according to the user's physical condition.

[0052] Currently available smart mattresses contain over 400 pressure columns that automatically adjust to the body for better support. However, this adjustment process is noisy. This invention replaces pressure columns with airbags. The volume changes of these airbags better adapt to the user's sleeping posture, conforming to and supporting the body for a more comfortable sleep experience. Due to the large number of airbags distributed and their ability to wrap around and conform to the user's body, and the presence of a connected vibration massager near the airbags, this invention provides acupressure massage, integrating traditional Chinese medicine principles. The surging friction of the vibration massager improves the dilation of skin capillaries, increasing blood circulation per unit area, raising skin surface temperature, and simultaneously increasing heat dissipation. The repeated localized pressing function induces the production of histamine-like substances in the body tissues. These substances, circulating throughout the body via the bloodstream, stimulate skin receptors, triggering neural reflexes and cortical reflexes that affect internal organs.

[0053] Furthermore, the sleep monitoring module is used to detect and determine the user's current state, which may be any one of deep sleep, REM sleep, light sleep, or insomnia.

[0054] Furthermore, when the sleep monitoring module detects that the user is in any of the following states: deep sleep, REM sleep, light sleep, or insomnia, the user's sleep state is sent to the smart controller via the data transmission module. The smart controller then uses the data transmission module to control the brainwave sleep aid submodule, temperature regulation submodule, angle adjustment submodule, and vibration massage submodule of the smart mattress.

[0055] REM sleep is a stage of sleep in which the eyes exhibit involuntary rapid eye movements. During this stage, the activity of neurons in the brain is similar to that during wakefulness. Most vivid dreams that can be recalled upon waking occur during REM sleep. It is the lightest of all sleep stages, and people who wake up during REM sleep are different from those in other sleep stages, feeling alert and refreshed. Therefore, many people feel tired after waking from a dream, and this fatigue returns after a while, requiring a second sleep for further rest. This invention, by sending alpha, beta, and theta waves to regulate sleep, will reduce sleep fatigue.

[0056] The smart mattress is equipped with multiple sensors that can detect the user's sleep time and duration, sleep temperature, sleep depth, sleep posture, turning time and frequency, waking time and frequency, blood pressure, heart rate, respiratory rate, fatigue level, and body shape sensing. It can detect the health status of different parts of the body by detecting the reaction when the body is massaged at acupoints. After connecting to a terminal, the detection results are fed back to the user, and a sleep quality report is generated to analyze the user's sleep quality. The mattress's softness, massage intensity, acupoints, and sleep temperature are continuously adjusted to improve the user's sleep quality and health status.

[0057] Example 2

[0058] Based on Embodiment 1, the present invention also provides a method for using a brainwave-assisted sleep mattress, such as... Figure 2 As shown, it includes the following steps:

[0059] like Figure 2 As shown, a method of using a brainwave-assisted sleep mattress is applied to a brainwave-assisted sleep mattress system as described in one of the objectives of this invention. The method of using the intelligent deep sleep mattress includes:

[0060] S1: System initialization starts the smart mattress via the smart controller;

[0061] S2: The sleep monitoring module detects the user's current state and sends it to the smart controller to determine whether the user is currently in a state of deep sleep, REM sleep, light sleep, or insomnia.

[0062] S3: Based on the judgment result, the intelligent controller sends the corresponding control model to the smart mattress through the data transmission module to control the sleep aid module to work and improve the user's current sleep state;

[0063] S4: The brainwave sleep aid submodule emits brainwaves of corresponding frequency combinations to the user; the temperature adjustment submodule adjusts the surface temperature of the smart mattress to create a comfortable contact temperature to improve the user's sleep; the angle adjustment submodule adjusts the smart mattress to a comfortable or preset angle for the user; the vibration massage submodule massages the user to aid sleep or relax.

[0064] Furthermore, in the initialization step, the user inputs user information and preset adjustment scheme through the intelligent controller. The intelligent controller then automatically generates a suitable massage strategy for the smart mattress based on the user's sleep and health status, and provides feedback adjustment on massage parameters such as massage position, massage intensity, and massage duration to improve the user's sleep quality and health status. It also evaluates the sleep quality improvement effect of the massage strategy, realizing massage adjustment based on intelligent biofeedback.

[0065] The working principle of the product of this invention is as follows:

[0066] By pre-entering relevant user information, including user weight, gender, age, and the corresponding mattress firmness, the intelligent controller system initializes. When someone uses the intelligent mattress of this invention, their weight changes. Based on the sensors on the intelligent mattress, the system obtains the user's position and weight on the bed and matches it with the pre-stored user information. If no match is found, no action is taken. If a preset user is matched, the system adjusts the firmness of the mattresses near the user based on their location. If this is the user's set sleep time, the sleep monitoring module analyzes the user's current sleep state. When the user is in a state of insomnia / awakeness... The smart mattress uses a brainwave sleep aid submodule to send alpha and beta waves. When the user is in light sleep, it sends k-complex, theta, and delta waves. When the user is in REM sleep, it sends alpha, beta, and theta waves. When the user is in deep sleep, it sends delta waves to help the user fall asleep. Simultaneously, a temperature regulation submodule adjusts the surface temperature of the smart mattress to create a comfortable contact temperature to improve sleep. Angle adjustment submodule adjusts the smart mattress to a comfortable or preset angle, and can adjust in real time according to the user's turning movements during sleep. A vibration massage submodule provides massage to help the user sleep or relax. After sleep, the smart controller analyzes the user's sleep, providing an analysis report and improvement suggestions to improve sleep quality.

[0067] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
