Description

Technical Field

[0001] This invention relates to the field of sleep assistance technology, and in particular to a sleep assistance method and system. Background Technology

[0002] Sleep is essential for life, crucial for replenishing energy, boosting immunity, and promoting normal growth and development. It allows the body to rest fully. Therefore, sleep is indispensable, and any sleep deprivation must be made up for; otherwise, it is extremely detrimental to health. However, with societal development, the pace of life is accelerating, work intensity is increasing, and life pressure is rising daily. Most people are experiencing a significant reduction in sleep time and a decline in sleep quality. Improving sleep quality is particularly important for the health of modern people in large cities.

[0003] More and more electronic devices can monitor users' sleep quality. The relationship between sleep and pillows is very close; a suitable pillow is crucial for ensuring high-quality sleep and maintaining cervical spine health. A suitable pillow supports the cervical spine, maintaining its natural physiological curvature. This helps reduce neck pressure and prevents excessive bending or stretching of the cervical spine. If the pillow is too high or too low, it can cause neck discomfort, thus affecting sleep quality. In related technologies, sleep aid apps are generally used for sleep assistance; however, these apps often only provide sleep assistance through sound or video alone and cannot achieve effective sleep aid results. Summary of the Invention

[0004] The technical problem solved by this invention is that sleep aids are generally provided through sleep-aid applications, but these applications often only provide sleep assistance through a single audio or video method, which cannot achieve an effective sleep aid effect.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: First aspect, a sleep-aiding method, comprising:

[0006] Step S100: Based on the sleep assistance information set by the user, a sleep reminder signal is triggered to enter the sleep assistance mode, which includes a voice reminder signal and an audio reminder signal;

[0007] Step S200: Collect the user's physiological data and determine the user's sleep state based on the physiological data;

[0008] Step S300: Adjust the voice reminder signal and sound reminder signal based on the sleep state;

[0009] Step S400: Collect pillow pressure information, adjust the airbag pressure information according to the pressure information and preset sleeping posture information, and establish the correspondence between the pressure information, preset sleeping posture and pressure control parameters;

[0010] Step S500: Based on the sleep state, the pressure control parameters are obtained using the correspondence to adjust the pillow pressure information.

[0011] In a preferred embodiment of the sleep assistance method of the present invention, step S100 specifically includes:

[0012] Step S101: The user sets sleep assistance information in advance, which includes sleep time, voice reminder signal and sound reminder signal;

[0013] Step S102: The user actively or passively triggers a sleep reminder signal to enter sleep assistance mode;

[0014] The user-initiated sleep reminder signal includes the user actively activating the sleep assistance mode and being reminded to start sleeping via a voice reminder signal.

[0015] The user-passively triggered sleep reminder signal includes automatically activating sleep assistance mode after the time for sleep has arrived, and reminding the user to start sleeping through a voice reminder signal.

[0016] As a preferred embodiment of the sleep assistance method described in this invention, the voice reminder signal includes one or more of meditation exercises, sleep-aid guidance, and bedtime stories;

[0017] The sound alerts include sleep-inducing music and white noise.

[0018] In a preferred embodiment of the sleep assistance method of the present invention, step S200 specifically includes:

[0019] Step S201: Collect the user's physiological data using a smart bracelet, including heart rate information and wrist movement information;

[0020] Step S202, the sleep state includes light sleep stage, deep sleep stage and wakefulness state, the smart bracelet monitors wrist movement information through a built-in three-axis accelerometer, the wrist movement information includes movement amplitude and movement frequency;

[0021] Step S203: Pre-determine a first amplitude threshold and a second amplitude threshold for the motion amplitude, and the first amplitude threshold is less than the second amplitude threshold;

[0022] Step S204: Predetermine a first frequency threshold and a second frequency threshold for the motion frequency, wherein the first frequency threshold is less than the second frequency threshold.

[0023] Step S205: Pre-determine a first heart rate threshold and a second heart rate threshold for heart rate information, wherein the first heart rate threshold is less than the second heart rate threshold;

[0024] Step S205: Determine the user's sleep state based on the first amplitude threshold, the second amplitude threshold, the first frequency threshold, the second frequency threshold, the first heart rate threshold, and the second heart rate threshold;

[0025] If the motion amplitude detected by the triaxial accelerometer is less than the first amplitude threshold, the motion frequency is less than the first frequency threshold, and the heart rate information is less than the first heart rate threshold, it indicates that this is the deep sleep stage.

[0026] If the motion amplitude detected by the triaxial accelerometer is greater than the first amplitude threshold and less than the second amplitude threshold, the motion frequency is greater than the first frequency threshold and less than the second frequency threshold, and the heart rate information is greater than the first heart rate threshold and less than the second heart rate threshold, it indicates that this is the light sleep stage.

[0027] If the motion amplitude detected by the triaxial accelerometer is greater than the second amplitude threshold, the motion frequency is greater than the second frequency threshold, and the heart rate information is greater than the second heart rate threshold, it indicates that the person is awake.

[0028] In a preferred embodiment of the sleep-aiding method of the present invention, the relationship between physiological data and sleep state is used as a first correspondence, including:

[0029] Step S206: Record the motion amplitude and frequency monitored by the triaxial accelerometer and the heart rate information collected by the smart bracelet in real time.

[0030] Step S207: Obtain the time points when the user's sleep state changes, and divide the time periods into deep sleep stage, light sleep stage and wakefulness state based on the time points.

[0031] In a preferred embodiment of the sleep assistance method of the present invention, step S300 specifically includes:

[0032] Step S301: When the user is awake, if the heart rate information, movement amplitude and movement frequency gradually decrease, the volume of the sound reminder signal is reduced.

[0033] Step S302: After the sound prompt in the sound reminder signal has finished playing, the sound reminder signal is played.

[0034] Step S303: If the user is detected to have entered a light sleep stage, reduce the volume of the sound reminder signal;

[0035] Step S304: If the user is detected to have entered a deep sleep stage, turn off the sound reminder signal.

[0036] In a preferred embodiment of the sleep assistance method of the present invention, step S400 specifically includes:

[0037] Step S401: Multiple air bladders are set on the pillow, and pressure sensors are set on each air bladder. The pressure sensors are used to acquire pressure information.

[0038] Step S402: Pre-enter the user's various sleeping positions and record the pressure information of each airbag under various sleeping positions as preset sleeping position information;

[0039] Step S403: The user actively selects preset sleeping position information and adjusts the pressure information of each airbag according to the preset sleeping position information.

[0040] Step S404: After the user's head rests on the pillow, the pressure information of each airbag is collected. If the pressure information is greater than the preset pressure threshold, the electric valve corresponding to the airbag is controlled to open, releasing the air in the airbag and making the pressure information of the airbag less than the pressure threshold. The pressure information of each airbag is then adjusted a second time.

[0041] As a preferred embodiment of the sleep assistance method of the present invention, step S400 further includes:

[0042] Step S405: Use the pressure information of each airbag after secondary adjustment and the corresponding electric valve opening time as pressure control parameters;

[0043] Step S406: The pressure information, preset sleeping posture information and pressure control parameters of each airbag after secondary adjustment are matched as a correspondence, and the pressure information and pressure control parameters of each airbag corresponding to the preset sleeping posture information are updated according to the correspondence.

[0044] As a preferred embodiment of the sleep assistance method of the present invention, step S500 specifically includes:

[0045] Smart bracelets are used to collect users' heart rate, exercise amplitude, and exercise frequency to determine their sleep status.

[0046] If the user is awake, the pressure information of each airbag is collected. If the pressure information is greater than the preset pressure threshold, the electric valve corresponding to the airbag is controlled to open, releasing the air in the airbag so that the pressure information of the airbag is less than the pressure threshold, and the pressure information of each airbag is adjusted again.

[0047] If the user is in deep sleep or light sleep, maintain constant pressure in each airbag and close all electric valves.

[0048] Secondly, a sleep aid system includes a data acquisition module, a control module, and a music playback module;

[0049] The acquisition module includes a smart bracelet and a pressure sensor. The smart bracelet is used to collect the user's heart rate information, exercise amplitude and exercise frequency. Multiple pressure sensors are provided, each corresponding to a different airbag. The pressure sensors are used to acquire pressure information.

[0050] The control module is used to determine the user's sleep state based on the physiological data, adjust the voice reminder signal and sound reminder signal based on the sleep state, adjust the pressure information of the airbag based on the pressure information and preset sleeping posture information, and adjust the pillow pressure information by obtaining pressure control parameters using the correspondence.

[0051] The music playback module is used to play voice reminder signals and sound reminder signals.

[0052] The beneficial effects of this invention are as follows: By using voice reminders to prompt users to put down their electronic devices and prepare for sleep, the invention addresses the issue. Electronic devices stimulate the brain to produce dopamine, significantly impacting sleep. Putting down electronic devices can significantly improve the sleep-inducing effect. Furthermore, by guiding users to focus on bodily sensations and breathing through voice reminders, the brain transitions from beta waves to alpha and theta waves, achieving a relaxing effect similar to light sleep. This helps the body enter a relaxed state and can significantly reduce the levels of stress hormones such as cortisol. This reduction in cortisol not only helps alleviate stress and anxiety but also improves overall health.

[0053] Playing soothing music and white noise via sound alerts helps users fall asleep. Collecting pillow pressure data and adjusting the airbag pressure based on this data and preset sleeping positions alters the support in different areas of the pillow—changing its shape and firmness—to regulate the user's sleeping posture and support the cervical spine, maintaining its natural curvature. This helps reduce neck pressure and prevents excessive bending or stretching of the cervical spine. A pillow that is too high or too low can cause neck discomfort, thus promoting better sleep. Furthermore, the automatic pillow adjustment based on pressure data makes it more convenient to use. Attached Figure Description

[0054] Figure 1 This is a schematic diagram of the basic process of a sleep-aiding method provided in one embodiment of the present invention.

[0055] Figure 2 This is a schematic diagram of a pillow structure for a sleep aid method provided in one embodiment of the present invention. Detailed Implementation

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0057] Example 1, referring to Figure 1 According to one embodiment of the present invention, a sleep-aiding method is provided, comprising:

[0058] Step S100: Based on the sleep assistance information set by the user, trigger the sleep reminder signal and enter the sleep assistance mode. The sleep assistance mode includes voice reminder signal and sound reminder signal.

[0059] Step S200: Collect the user's physiological data and determine the user's sleep state based on the physiological data;

[0060] Step S300: Adjust the voice reminder signal and sound reminder signal based on the sleep state;

[0061] Step S400: Collect pillow pressure information, adjust the airbag pressure information according to the pressure information and preset sleeping posture information, and establish the correspondence between pressure information, preset sleeping posture and pressure control parameters.

[0062] Step S500: Based on the sleep state, the pressure control parameters are obtained using the corresponding relationship to adjust the pillow pressure information.

[0063] In this preferred embodiment, a voice reminder signal prompts the user to put down their electronic device and begin preparing for sleep. Electronic devices stimulate the brain to produce dopamine, which significantly affects sleep. Putting down the device can significantly improve the sleep-aiding effect. Guiding the user to focus on bodily sensations and breathing through voice reminders helps the brain transition from beta waves to alpha and theta waves, achieving a relaxing effect similar to light sleep. This helps the body enter a relaxed state and can significantly reduce the level of stress hormones (such as cortisol). This reduction in hormones not only helps alleviate stress and anxiety but also improves overall health.

[0064] During sleep, our brains go through multiple sleep cycles, each lasting approximately 90 minutes, including light sleep and deep sleep stages. During sleep, the brain's electrical activity gradually transitions from beta waves (present when awake) to alpha waves, theta waves, and finally delta waves (present during deep sleep). If the timing isn't controlled properly and you wake up during deep sleep, you'll experience noticeable signs of not having slept enough. For example, you might feel groggy upon waking, as if you've slept but haven't. This groggy feeling is uncomfortable, making you wish you hadn't slept at all; this is a phenomenon known as sleep inertia. Sleep inertia causes the brain to be in a temporary state of inhibition, so many people often experience a prolonged period of cognitive and sensory decline after a traditional nap, and it can take anywhere from ten minutes to several hours to return to normal.

[0065] Playing soothing music and white noise via sound alerts helps users fall asleep. Collecting pillow pressure data and adjusting the airbag pressure based on this data and preset sleeping positions alters the support in different areas of the pillow—changing its shape and firmness—to regulate the user's sleeping posture and support the cervical spine, maintaining its natural curvature. This helps reduce neck pressure and prevents excessive bending or stretching of the cervical spine. A pillow that is too high or too low can cause neck discomfort, thus promoting better sleep. Furthermore, the automatic pillow adjustment based on pressure data makes it more convenient to use.

[0066] Example 2, refer to Figure 1 and Figure 2 According to one embodiment of the present invention, a sleep-aiding method is provided, comprising:

[0067] Step S100 specifically includes:

[0068] Step S101: The user sets sleep assistance information in advance, which includes sleep time, voice reminder signal and sound reminder signal;

[0069] Step S102: The user actively or passively triggers a sleep reminder signal to enter sleep assistance mode;

[0070] User-initiated sleep reminder signals include users actively activating sleep assistance mode and being reminded to start sleeping via voice reminder signals;

[0071] Passive sleep reminder signals triggered by the user include automatically activating sleep assistance mode after the time for sleep has arrived, and reminding the user to start sleeping through voice reminders.

[0072] Voice prompts include one or more of the following: meditation exercises, sleep guidance, and bedtime stories;

[0073] Sound alerts include sleep-inducing music and white noise.

[0074] In this preferred embodiment, the user pre-sets their sleep time, such as starting to sleep at 10:30 PM. At 10:30 PM, an automatic voice reminder signal is issued to remind the user to put down their electronic devices and prepare for sleep. Then, meditation exercises, sleep-aiding guidance, and bedtime stories are played to assist the user in falling asleep. At this point, the sleep reminder signal is passively triggered, entering sleep-aid mode.

[0075] Users can also actively trigger sleep reminders to play meditation exercises, sleep aids, and bedtime stories to help them fall asleep. At the same time, they can turn off preset sleep times to prevent voice reminders from disturbing their sleep.

[0076] White noise function: By playing natural sounds (such as rain, ocean waves, wind, etc.) or white noise, it masks ambient noise and helps users relax and fall asleep. For example, the "White Noise" app offers a variety of natural sounds and white noise options, which users can choose according to their preferences.

[0077] Guided meditation feature: Provides voice guidance for users to practice meditation, helping to relax the mind and body and relieve stress. Applications: Apps such as "Tides" and "Little Sleep" offer guided meditation content.

[0078] Sleep story feature: Plays soothing bedtime stories to help users relax and fall asleep. Applications: Apps such as "Himalaya" and "Little Sleep" offer various types of sleep stories. Personalized sleep stories can also be generated based on user needs and preferences.

[0079] Step S201: Collect the user's physiological data using a smart bracelet. The physiological data includes heart rate information and wrist movement information.

[0080] Step S202, the sleep state includes light sleep stage, deep sleep stage and wakefulness state. The smart bracelet monitors wrist movement information through the built-in three-axis accelerometer. The wrist movement information includes movement amplitude and movement frequency.

[0081] Step S203: Pre-determine a first amplitude threshold and a second amplitude threshold for the motion amplitude, and the first amplitude threshold is less than the second amplitude threshold;

[0082] Step S204: Predetermine a first frequency threshold and a second frequency threshold for the motion frequency, wherein the first frequency threshold is less than the second frequency threshold.

[0083] Step S205: Pre-determine a first heart rate threshold and a second heart rate threshold for heart rate information, wherein the first heart rate threshold is less than the second heart rate threshold;

[0084] Step S205: Determine the user's sleep state based on the first amplitude threshold, the second amplitude threshold, the first frequency threshold, the second frequency threshold, the first heart rate threshold, and the second heart rate threshold;

[0085] If the motion amplitude detected by the triaxial accelerometer is less than the first amplitude threshold, the motion frequency is less than the first frequency threshold, and the heart rate information is less than the first heart rate threshold, it indicates that this is the deep sleep stage.

[0086] If the motion amplitude detected by the triaxial accelerometer is greater than the first amplitude threshold and less than the second amplitude threshold, the motion frequency is greater than the first frequency threshold and less than the second frequency threshold, and the heart rate information is greater than the first heart rate threshold and less than the second heart rate threshold, it indicates that this is the light sleep stage.

[0087] If the motion amplitude detected by the triaxial accelerometer is greater than the second amplitude threshold, the motion frequency is greater than the second frequency threshold, and the heart rate information is greater than the second heart rate threshold, it indicates that the person is awake.

[0088] In this preferred embodiment, an existing smart bracelet can collect the user's heart rate and wrist movement information, including amplitude and frequency. The user's sleep state is determined by the heart rate, amplitude, and frequency—specifically, whether the user is in light sleep, awake, or deep sleep. The heart rate and wrist movement information (amplitude and frequency) collected during the user's light sleep, awake, and deep sleep stages are averaged and used as a reference for setting a first amplitude threshold, a second amplitude threshold, a first frequency threshold, a second frequency threshold, a first heart rate threshold, and a second heart rate threshold.

[0089] The relationship between physiological data and sleep state is used as the first correspondence, including:

[0090] Step S206: Record the motion amplitude and frequency monitored by the triaxial accelerometer and the heart rate information collected by the smart bracelet in real time.

[0091] Step S207: Obtain the time points when the user's sleep state changes, and divide the time periods into deep sleep stage, light sleep stage and wakefulness state according to the time points.

[0092] In this embodiment, the preferred method is to better record the duration of the user's deep sleep stage, light sleep stage, and awake state, thereby determining the user's sleep quality, and to record the amplitude and frequency of movement corresponding to the deep sleep stage, light sleep stage, and awake state.

[0093] Step S301: When the user is awake, if the heart rate, movement amplitude, and movement frequency gradually decrease, the volume of the sound reminder signal is reduced.

[0094] Step S302: After the sound prompt in the sound reminder signal has finished playing, play the sound reminder signal;

[0095] Step S303: If the user is detected to have entered a light sleep stage, reduce the volume of the sound reminder signal;

[0096] Step S304: If the user is detected to have entered a deep sleep stage, turn off the sound reminder signal.

[0097] In this preferred embodiment, by adjusting the voice and sound reminder signals according to the deep sleep stage, light sleep stage, and wakefulness state, it is beneficial to help users fall asleep while preventing the voice and sound reminder signals from disturbing the user and causing difficulty falling asleep. Existing sleep aid music typically turns off after half an hour and cannot adjust the volume according to the user's sleep state. Even after the user enters light sleep, the previous playback volume is still used, easily waking the user again. Furthermore, sound reminder signals are unnecessary when the user enters deep sleep. The sound reminder signals can be automatically turned off, reducing power consumption.

[0098] During light sleep, the body will make slight movements. After the smart bracelet detects these movements, it will determine that the user is in a light sleep state.

[0099] Deep sleep stage: Muscles are completely relaxed, and the frequency and amplitude of movement are extremely low. Smart bracelets determine that the user is in deep sleep based on these characteristics.

[0100] Awake state: When the movement is frequent and significant, the smart bracelet will determine that the user is awake.

[0101] Step S401: Multiple air bladders are set on the pillow, and pressure sensors are set on each air bladder. The pressure sensors are used to acquire pressure information.

[0102] Step S402: Pre-enter the user's various sleeping positions and record the pressure information of each airbag under various sleeping positions as preset sleeping position information;

[0103] Step S403: The user actively selects preset sleeping position information and adjusts the pressure information of each airbag according to the preset sleeping position information.

[0104] Step S404: After the user's head rests on the pillow, the pressure information of each airbag is collected. If the pressure information is greater than the preset pressure threshold, the electric valve corresponding to the airbag is controlled to open, releasing the air in the airbag and making the pressure information of the airbag less than the pressure threshold. The pressure information of each airbag is then adjusted a second time.

[0105] Step S405: Use the pressure information of each airbag after secondary adjustment and the corresponding electric valve opening time as pressure control parameters;

[0106] Step S406: The pressure information, preset sleeping position information and pressure control parameters of each airbag after secondary adjustment are matched as a correspondence, and the pressure information and pressure control parameters of each airbag corresponding to the preset sleeping position information are updated according to the correspondence.

[0107] In this preferred embodiment, pillow pressure information is collected, and the pressure of the airbags is adjusted based on this pressure information and preset sleeping posture information. This changes the support force in different areas of the pillow, that is, it changes the shape and firmness of the pillow, thereby adjusting the user's sleeping posture and supporting the cervical spine to maintain its natural physiological curvature. This helps reduce neck pressure and avoids excessive bending or stretching of the cervical spine. If the pillow is too high or too low, it can cause neck discomfort, thus promoting better sleep. Moreover, by automatically adjusting the pillow using pillow pressure information, it is more convenient to use. The pressure information and pressure control parameters of each airbag are updated after each adjustment, so the user can directly use the previously adjusted pillow next time, making it more comfortable and convenient to use without having to manually adjust the pillow each time.

[0108] Smart bracelets are used to collect users' heart rate, exercise amplitude, and exercise frequency to determine their sleep status.

[0109] If the user is awake, the pressure information of each airbag is collected. If the pressure information is greater than the preset pressure threshold, the electric valve corresponding to the airbag is controlled to open, releasing the air in the airbag so that the pressure information of the airbag is less than the pressure threshold, and the pressure information of each airbag is adjusted again.

[0110] If the user is in deep sleep or light sleep, maintain constant pressure in each airbag and close all electric valves.

[0111] In this preferred embodiment, the air in the airbag can be automatically released by an electric valve, so that the pressure of the airbag is less than the pressure threshold. This allows for automatic fine-tuning of the support force at various positions of the pillow, making it more comfortable for the user.

[0112] In one preferred embodiment, reference is made to Figure 2 , Figure 2 In the attached diagram, 1 represents the pillow, 2 represents the pillowcase, and 4 represents the diaphragm inside the pillow. The diaphragm 4 divides the inside of the inflatable pillow into multiple air bladders 3. Each air bladder 3 is equipped with a pressure sensor. Each air bladder 3 is connected to one end of an air tube 5, and the other end of the air tube 5 can be connected to an air storage bottle for inflating each air bladder 3. When the electric valve 6 on the air tube 5 is opened, it can release the air inside the air bladder 3 and reduce the pressure of the air bladder 3.

[0113] Example 2 is another embodiment of the present invention. This embodiment differs from the first embodiment in that it provides a sleep assistance system, including a data acquisition module, a control module, and a music playback module.

[0114] The data acquisition module includes a smart bracelet and pressure sensors. The smart bracelet is used to collect the user's heart rate, exercise amplitude, and exercise frequency. There are multiple pressure sensors, each corresponding to a different airbag, which are used to acquire pressure information.

[0115] The control module is used to determine the user's sleep state based on physiological data, adjust the voice reminder signal and sound reminder signal based on the sleep state, adjust the pressure information of the airbag based on pressure information and preset sleeping position information, and adjust the pillow pressure information by obtaining pressure control parameters using the corresponding relationship.

[0116] The music playback module is used to play voice and sound reminder signals.

[0117] Voice prompts remind users to put down their electronic devices and prepare for sleep. Electronic devices stimulate the brain to release dopamine, which significantly affects sleep. Putting down electronic devices can significantly improve the effectiveness of sleep aids. Voice prompts guide users to focus on bodily sensations and breathing, helping the brain transition from beta waves to alpha and theta waves, achieving a relaxing effect similar to light sleep. This helps the body enter a relaxed state and can significantly reduce levels of stress hormones such as cortisol. This reduction in cortisol not only helps alleviate stress and anxiety but also improves overall health.

[0118] Playing soothing music and white noise via sound alerts helps users fall asleep. Collecting pillow pressure data and adjusting the airbag pressure based on this data and preset sleeping positions alters the support in different areas of the pillow—changing its shape and firmness—to regulate the user's sleeping posture and support the cervical spine, maintaining its natural curvature. This helps reduce neck pressure and prevents excessive bending or stretching of the cervical spine. A pillow that is too high or too low can cause neck discomfort, thus promoting better sleep. Furthermore, the automatic pillow adjustment based on pressure data makes it more convenient to use.
