Description

Technical Field

[0001] This invention belongs to the field of smart wearable technology, and specifically relates to an adaptive smart ring and its control method. Background Technology

[0002] Rings are a common type of jewelry worn on the hands. With the continuous development of technology, smart wearable devices are increasingly being used in daily life to facilitate activities such as motion monitoring, sleep monitoring, and health monitoring. Smart rings, with their compact size and other advantages, have emerged as a result. However, a major drawback of smart rings is that everyone's fingers are different sizes, making it difficult to find rings suitable for people with different finger sizes. Another issue is that rings often come into contact with water. Although current smart rings are waterproof to prevent water damage to their internal electronic components, in real life, if water remains between the ring and the finger for an extended period, it can cause discomfort and affect the wearing experience. Furthermore, prolonged water exposure can damage the ring's surface. The need to manually move the ring and wipe it dry after each contact with water is also inconvenient for users.

[0003] There are also adjustable smart rings in the prior art, such as patent application CN201910956067.5, which discloses an adjustable smart ring that can adjust the ring size and provide humidity reminders. However, it only has a reminder function, and the result of this function is still not intelligent enough. It does not effectively help users solve the pain point problem of matching the application scenarios of smart rings. Summary of the Invention

[0004] This invention relates to an adaptive smart ring, which has an adjustable ring body, including a fixed end and a movable end located on its outer side; the ring body includes an acceleration sensor, a displacement sensor, a humidity sensor and a controller, the acceleration sensor, the displacement sensor and the humidity sensor are all connected to the controller, the controller receives the sensing signals from the acceleration sensor, the displacement sensor and the humidity sensor, compares and judges them, and outputs a control signal to control the movable end to move and adjust the size of the ring body;

[0005] The humidity sensor is used to detect the humidity value of the finger wearing the smart ring. After receiving the humidity value, the controller compares the humidity value with a preset humidity threshold. If the humidity value is greater than the preset humidity threshold, the size of the smart ring is increased; if the humidity value is less than the preset humidity threshold, the size of the smart ring remains unchanged.

[0006] The adaptive smart ring, wherein the displacement sensor is activated upon receiving a first start signal from the controller to detect a first displacement value of the smart ring on the finger and transmits the first displacement value to the controller. Upon receiving the first displacement value, the controller compares and judges it. If the first displacement value is greater than a first displacement threshold, the controller sends a control signal to reduce the size of the ring body.

[0007] The adaptive smart ring, wherein the accelerometer is used to detect the acceleration value of the smart ring and send the acceleration value to the controller. After receiving the acceleration value, the controller compares and judges whether the first displacement value is greater than the second displacement threshold and the acceleration value is greater than the first acceleration threshold. If both the first displacement value and the acceleration value are greater than the first acceleration threshold, the controller sends a control signal to reduce the ring body. The second displacement threshold is less than the first displacement threshold.

[0008] The adaptive smart ring, wherein the controller comprises: a humidity comparison module, a displacement comparison module, an acceleration comparison module, a first start module, a second start module, a processing module, and an output control module; the input terminal of the humidity comparison module is connected to the humidity sensor, and the output terminal is connected to the processing module; the input terminal of the displacement comparison module is connected to the displacement sensor, and the output terminal is connected to the processing module; the input terminal of the acceleration comparison module is connected to the acceleration sensor, and the output terminal is connected to the processing module; the output terminal of the processing module is connected to the input terminals of the first start module, the second start module, and the output control module, respectively; the output terminal of the first start module is connected to the displacement sensor, and the output terminal of the second start module is connected to the acceleration sensor.

[0009] The adaptive smart ring includes a communication module that interacts with a terminal.

[0010] A control method for an adaptively adjusting smart ring as described in any of the above claims includes the following steps:

[0011] S1. The humidity sensor detects the humidity value of the finger wearing the smart ring and transmits the humidity value to the controller;

[0012] S2. After receiving the humidity value, the controller compares the humidity value with a preset humidity threshold. If the humidity value is greater than the preset humidity threshold, proceed to step S4; if the humidity value is less than the preset humidity threshold, proceed to step S3.

[0013] S3. Keep the size of the smart ring body unchanged;

[0014] S4. The controller sends a control signal to increase the first scale value of the ring body of the smart ring, and simultaneously sends a first start signal to the first start module and a second start signal to the second start module. After receiving the first start signal, the first start module controls the displacement sensor to turn on, and after receiving the second start signal, the second start module controls the acceleration sensor to turn on.

[0015] S5. After the displacement sensor is turned on, it detects the first displacement value of the smart ring moving on the finger and sends the first displacement value to the controller. After the acceleration sensor is turned on, it detects the acceleration value of the smart ring moving on the finger and sends the acceleration value to the controller.

[0016] S6. After receiving the first acceleration value, the controller compares and judges whether the first acceleration value is greater than the first acceleration threshold and the first displacement value is greater than the second displacement threshold. If the first acceleration value is less than the first acceleration threshold, the controller judges whether the first displacement value is greater than the first displacement threshold in real time. If the first displacement value is greater than the first displacement threshold, the controller sends a control signal to decrease the second scale value of the ring body.

[0017] S7. If the ring body decreases the second scale value, and the second acceleration value of the smart ring is detected again by the accelerometer, and if the second acceleration value is greater than the second acceleration threshold, then the third scale value of the ring body is decreased.

[0018] S8. After reducing the third scale value of the ring body, the displacement sensor detects whether there is a second displacement of the ring. If there is a second displacement, a vibration alarm is issued. If there is no second displacement, the current state is maintained.

[0019] In the control method described above, the second displacement threshold is less than the first displacement threshold, and the second acceleration threshold is much smaller than the first acceleration threshold.

[0020] In the control method described above, the second scale value is the same as the first scale value, and the third scale value is much smaller than the second scale value.

[0021] In the control method described above, the second scale value is different from the first scale value and the second scale value is greater than the first scale value, while the third scale value is much smaller than the second scale value.

[0022] In the control method described above, the second displacement is much smaller than the first displacement.

[0023] This invention proposes an adaptive smart ring and its control method. It can detect humidity using a humidity sensor and adjust the size of the smart ring body accordingly. This allows the smart ring to move downwards on the finger under the influence of gravity. The downward movement alters the original contact surface between the smart ring and the finger, exposing moisture to the air and making it easier to dry or wipe away. Simultaneously, to prevent the smart ring from slipping off the finger, displacement and acceleration sensors are used to detect and judge the movement status, and the size of the ring body is adjusted based on the detection and judgment results. One improvement of this invention is the inclusion of a humidity sensor in the smart ring. The size of the ring is adjusted based on the sensor's detection results, preventing the ring from remaining damp for extended periods or becoming difficult to wipe clean. This overcomes the limitations of existing technologies where humidity detection merely serves as a reminder of excessive humidity. By coordinating humidity detection with controller control, the user experience is improved. Another improvement is the inclusion of displacement and acceleration sensors. These sensors activate based on the humidity sensor's detection results, meaning they activate only when the humidity exceeds a threshold. The ring size adjustment is coordinated with the detection results from the displacement and acceleration sensors, preventing the smart ring from slipping off the finger during adjustment and improving its safety. Attached Figure Description

[0024] Figure 1 This is a schematic diagram of an adaptive adjustment smart ring according to the present invention.

[0025] Figure 2 This is a schematic diagram of the controller of the present invention.

[0026] Figure 3 This is a schematic diagram of the control method of the present invention. Detailed Implementation

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] To address the issues of existing smart rings requiring drying after sweating or getting wet, and to prevent discomfort caused by contact between the ring and finger skin due to sweat or water, as well as the impact of prolonged dampness on the ring's surface performance, this application aims to improve the user experience of smart rings. It automatically detects humidity and adjusts the ring size accordingly, further enhancing the safety of the adjustment process by incorporating displacement and acceleration detection.

[0029] like Figure 1 The diagram shown illustrates an adaptive smart ring according to the present invention. The smart ring has an adjustable ring body, which includes a fixed end and a movable end located on its outer side. The ring body includes an accelerometer, a displacement sensor, a humidity sensor, and a controller. The accelerometer, displacement sensor, and humidity sensor are all connected to the controller. The controller receives the sensing signals from the accelerometer, displacement sensor, and humidity sensor, compares and judges them, and then outputs a control signal to control the movable end to move and adjust the size of the ring body.

[0030] The humidity sensor is used to detect the humidity value of the finger wearing the smart ring. After receiving the humidity value, the controller compares the humidity value with a preset humidity threshold. If the humidity value is greater than the preset humidity threshold, the size of the smart ring is increased; if the humidity value is less than the preset humidity threshold, the size of the smart ring remains unchanged.

[0031] Preferably, the adjustment method of the ring body can be selected from existing adjustment methods, such as setting a micro motor and driving the micro motor through the output drive signal of the controller so that the moving end can move on its own; or setting a rotating shaft and changing the distance between the moving end and the fixed end by rotating the shaft, thereby changing the space around the ring body to make it smaller or larger, etc.

[0032] Preferably, the aforementioned acceleration sensor can be selected to detect lateral movement acceleration or longitudinal movement acceleration according to the control signal. Lateral movement acceleration detection is the acceleration detection that is commonly found in smart wearable devices, which can detect running speed or direction of movement. Longitudinal movement acceleration is the acceleration selected in this application that can determine the sliding of the smart ring on the finger. Since the smart ring increases in size when the finger moves downward, the smart ring will move downward or slide down due to gravity. This downward acceleration is a vertical or longitudinal process.

[0033] Preferably, when the controller determines that the humidity is greater than the threshold, the acceleration sensor is activated. At this time, the controller selects the acceleration sensor as the longitudinal movement acceleration detection. Preferably, there can be two acceleration sensors, one for lateral acceleration detection and the other for longitudinal movement acceleration detection. The lateral movement acceleration detection is used to be activated continuously to detect the user's movement status, while the longitudinal acceleration detection is activated after receiving the controller's control signal. The controller's control signal is only issued after determining that the humidity is greater than the threshold.

[0034] The adaptive smart ring, wherein the displacement sensor is activated upon receiving a first start signal from the controller to detect a first displacement value of the smart ring on the finger and transmits the first displacement value to the controller. Upon receiving the first displacement value, the controller compares and judges it. If the first displacement value is greater than a first displacement threshold, the controller sends a control signal to reduce the size of the ring body.

[0035] The adaptive smart ring, wherein the accelerometer is used to detect the acceleration value of the smart ring and send the acceleration value to the controller. After receiving the acceleration value, the controller compares and judges whether the first displacement value is greater than the second displacement threshold and the acceleration value is greater than the first acceleration threshold. If both the first displacement value and the acceleration value are greater than the first acceleration threshold, the controller sends a control signal to reduce the ring body. The second displacement threshold is less than the first displacement threshold.

[0036] like Figure 2 The diagram shows a schematic of the controller for this invention. The adaptive smart ring controller includes: a humidity comparison module, a displacement comparison module, an acceleration comparison module, a first start-up module, a second start-up module, a processing module, and an output control module. The input terminal of the humidity comparison module is connected to the humidity sensor, and its output terminal is connected to the processing module. The input terminal of the displacement comparison module is connected to the displacement sensor, and its output terminal is connected to the processing module. The input terminal of the acceleration comparison module is connected to the acceleration sensor, and its output terminal is connected to the processing module. The output terminal of the processing module is connected to the input terminals of the first start-up module, the second start-up module, and the output control module, respectively. The output terminal of the first start-up module is connected to the displacement sensor, and the output terminal of the second start-up module is connected to the acceleration sensor.

[0037] The adaptive smart ring includes a communication module that interacts with a terminal.

[0038] Preferably, the communication module is a Bluetooth module, and the smart ring communicates with the terminal via the Bluetooth module to configure parameters and read data from the smart ring.

[0039] Preferably, the size or adjustable scale value of the smart ring's ring body can be read or set by the communication module with the terminal. That is, when the user wears the smart ring and adjusts it to a suitable ring size, the terminal can read the specific value of the ring body and calculate the first, second, or third scale value based on the specific value of the ring body, forming a data analysis result as a typical recommendation value for the user to view directly on the terminal. The first, second, or third scale value is the adjustable size value of the smart ring's ring body, that is, the ring circumference value that is increased or decreased during the adjustment process.

[0040] like Figure 3 The diagram shown is a schematic flowchart of the control method of the present invention. A control method for an adaptively adjusting smart ring as described in any of the above claims includes the following steps:

[0041] S1. The humidity sensor detects the humidity value of the finger wearing the smart ring and transmits the humidity value to the controller;

[0042] S2. After receiving the humidity value, the controller compares the humidity value with a preset humidity threshold. If the humidity value is greater than the preset humidity threshold, proceed to step S4; if the humidity value is less than the preset humidity threshold, proceed to step S3.

[0043] S3. Keep the size of the smart ring body unchanged;

[0044] S4. The controller sends a control signal to increase the first scale value of the ring body of the smart ring, and simultaneously sends a first start signal to the first start module and a second start signal to the second start module. After receiving the first start signal, the first start module controls the displacement sensor to turn on, and after receiving the second start signal, the second start module controls the acceleration sensor to turn on.

[0045] S5. After the displacement sensor is turned on, it detects the first displacement value of the smart ring moving on the finger and sends the first displacement value to the controller. After the acceleration sensor is turned on, it detects the acceleration value of the smart ring moving on the finger and sends the acceleration value to the controller.

[0046] S6. After receiving the first acceleration value, the controller compares and judges whether the first acceleration value is greater than the first acceleration threshold and the first displacement value is greater than the second displacement threshold. If the first acceleration value is less than the first acceleration threshold, the controller judges whether the first displacement value is greater than the first displacement threshold in real time. If the first displacement value is greater than the first displacement threshold, the controller sends a control signal to decrease the second scale value of the ring body.

[0047] S7. If the ring body decreases the second scale value, the second acceleration value of the smart ring is detected again by the acceleration sensor. If the second acceleration value is greater than the second acceleration threshold, the third scale value of the ring body is decreased.

[0048] S8. After reducing the third scale value of the ring body, the displacement sensor detects whether there is a second displacement of the ring. If there is a second displacement, a vibration alarm is issued. If there is no second displacement, the current state is maintained.

[0049] In the control method described above, the second displacement threshold is less than the first displacement threshold, and the second acceleration threshold is much smaller than the first acceleration threshold.

[0050] In the control method described above, the second scale value is the same as the first scale value, and the third scale value is much smaller than the second scale value.

[0051] In the control method described above, the second scale value is different from the first scale value and the second scale value is greater than the first scale value, while the third scale value is much smaller than the second scale value.

[0052] In the control method described above, the second displacement is much smaller than the first displacement.

[0053] This invention proposes an adaptive smart ring and its control method. It can detect humidity using a humidity sensor and adjust the size of the smart ring body accordingly. This allows the smart ring to move downwards on the finger under the influence of gravity. The downward movement alters the original contact surface between the smart ring and the finger, exposing moisture to the air and making it easier to dry or wipe away. Simultaneously, to prevent the smart ring from slipping off the finger, displacement and acceleration sensors are used to detect and judge the movement status, and the size of the ring body is adjusted based on the detection and judgment results.

By coordinating humidity detection with controller control, the user experience is improved. Another improvement is the inclusion of displacement and acceleration sensors. These sensors activate based on the humidity sensor's detection results, meaning they activate only when the humidity exceeds a threshold.
