Summary of the Invention

[0003] The purpose of this application is to provide a smart ring and a method for adjusting the inner lining of the smart ring, which enables the smart ring to achieve a precise fit with the wearing part of the ring, effectively improving the user's wearing comfort and the accuracy of measurement data.

[0004] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0005] According to one aspect of the embodiments of this application, a smart ring is provided, the smart ring comprising:

[0006] The ring body includes an annular cavity formed by an outer ring and an inner ring. The annular cavity includes a first chamber and a second chamber. The first chamber contains a first filler, and the second chamber contains a second filler. The inner ring is made of a flexible material. A data acquisition module, located within the annular cavity, is used to acquire physiological signals from the ring wearer. An isolation assembly for dividing the annular cavity into a first chamber and a second chamber; A control module, disposed in the annular inner cavity and connected to the isolation component, is used to control the isolation component to make the first chamber and the second chamber communicate. The first filler and the second filler fuse and undergo a chemical reaction in the communicated annular inner cavity to form a cured liner adapted to the ring wearing area.

[0007] In one embodiment of this application, the isolation component includes: An isolation membrane is disposed between the first chamber and the second chamber; A heating element is in contact with the insulating membrane, and the control module is used to control the heating element to melt the insulating membrane so that the first chamber and the second chamber are connected.

[0008] In one embodiment of this application, the separator film includes a thermoplastic separator film or a thin film made of an electrolytic material.

[0009] In one embodiment of this application, the first filler is a liquid resin; the second filler is a liquid curing agent.

[0010] In one embodiment of this application, the inner ring of the ring is made of a transparent flexible material, and when the acquisition module acquires physiological signals, light or electrical signals can penetrate the inner ring of the ring.

[0011] According to one aspect of the embodiments of this application, a method for adjusting the inner lining of a smart ring is provided, the method comprising: An adjustment command is sent to the smart ring via an external device, the adjustment command indicating that the inner lining of the smart ring is to be adjusted; If the smart ring receives the adjustment command, it controls the isolation component to connect the first chamber and the second chamber.

[0012] In one embodiment of this application, before the smart ring receives the adjustment command, it further includes: Detect whether the smart ring is worn on the wearing area; When the smart ring is detected to be worn on the wearing area, an adjustment command is sent to the smart ring via the external device.

[0013] In one embodiment of this application, controlling the isolation assembly to communicate the first chamber and the second chamber includes: The built-in heating element is driven to work to melt the isolation membrane disposed between the first chamber and the second chamber, thereby connecting the first chamber and the second chamber; wherein the heating element is in contact with the isolation membrane.

Detailed Implementation

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0028] Existing smart rings, health monitoring rings, and other devices typically use a fixed inner ring shape and lining. However, significant differences in shape, thickness, and contour exist between different users, and even between different fingers of the same user, leading to common problems of discomfort and poor fit for rings with fixed linings.

[0029] Therefore, this application provides a smart ring 1 to solve the above problems.

[0030] Figure 1 The schematic diagram illustrates a structure for wearing a smart ring on a circular part according to an embodiment of this application. Figure 2 This illustration shows a schematic diagram of a structure for wearing a smart ring on an oval-shaped part according to an embodiment of this application. Figure 1 , Figure 2 As shown, the smart ring 1 provided in this application includes: a ring body 10, an isolation component 12, a control module 11, and a battery 16.

[0031] In some embodiments of this application, the ring body 10 may include an outer ring 101 and an inner ring 102.

[0032] The ring body 10 is the basic supporting structure of the smart ring 1. Its core functions are to fix various electronic components, adapt to the finger for wearing, and ensure stability during the measurement process. The outer ring 101 refers to the main structure and appearance carrier of the ring body 10, and plays a core role in protecting the internal components and defining the product's form and style. The inner ring 102 is the part that directly contacts the finger's skin. Its core tasks are to ensure wearing comfort, fix the optical sensor, and maintain stable contact with the skin to obtain high-quality signals.

[0033] In some embodiments of this application, the outer ring 101 of the ring can be made of metal, which constitutes the main skeleton of the smart ring 1, providing structural strength for the smart ring 1 and accommodating internal components. The metal material may include aluminum alloy, titanium alloy, stainless steel, etc.

[0034] In some embodiments of this application, the inner ring 102 can be fixedly connected to the inner wall of the outer ring 101 by injection molding. During injection molding, liquid silicone (the material of the inner ring 102) is injected into a pre-set groove on the inner wall of the outer ring 101 (or directly adhered to the inner wall), and after curing, it forms a strong connection with the outer ring 101 through "mechanical interlocking and molecular-level adhesion". The liquid silicone fills the micro-textures (such as the rough surface machined by CNC) on the inner wall of the outer ring 101, and after curing, it forms an anchoring structure with significantly higher peel strength than adhesive bonding, snap-fit ​​connections, etc.

[0035] In some embodiments of this application, the annular grooves of the inner ring 102 and the outer ring 101 are completely fitted together, forming a hollow annular cavity. The annular cavity may include a first chamber 13 and a second chamber 14.

[0036] In some embodiments of this application, the annular cavity can be divided circumferentially into a first chamber 13 and a second chamber 14. The annular cavity can also be divided circumferentially into a first chamber 13 and a second chamber 14 on an even basis. Alternatively, the annular cavity can be divided circumferentially into a first chamber 13 and a second chamber 14 proportionally.

[0037] In other embodiments of this application, the annular cavity may be radially divided into a first chamber 13 and a second chamber 14. The annular cavity may be radially divided into a first chamber 13 and a second chamber 14 on an even basis. The annular cavity may be radially divided into a first chamber 13 and a second chamber 14 proportionally.

[0038] In some embodiments of this application, the inner wall of the cavity may be treated with plasma to ensure the compatibility of the filler with the cavity wall and avoid the generation of residual bubbles.

[0039] In some embodiments of this application, the volumes of the first chamber 13 and the second chamber 14 may be equal, that is, the volume ratio of the first chamber 13 to the second chamber 14 may be 1:1.

[0040] In some other embodiments of this application, the volumes of the first chamber 13 and the second chamber 14 may not be equal. For example, the volume ratio of the first chamber 13 to the second chamber 14 may be 2:3, or the volume ratio of the first chamber 13 to the second chamber 14 may be 2:1. The volume ratio of the first chamber 13 to the second chamber 14 may also be other ratios.

[0041] To achieve the core design goal of the smart ring 1 to adapt to the wearing part 2, the inner ring 102 needs to provide a precise initial fit reference and then provide adaptive deformation space for the curing process. Therefore, a flexible material can be used to make the inner ring 102.

[0042] Flexible materials possess excellent flexibility and conformability. When worn, they undergo slight deformation under the natural pressure of the ring wearing area 2, closely conforming to the subtle contours of the skin surface. This precisely transmits the personalized shape of the ring wearing area 2 to the internal annular cavity, providing a constraint benchmark for the subsequent curing of the first and second fillers. In contrast, if rigid materials (such as metal or hard plastic) are used to make the inner ring 102 of the ring, its shape remains fixed and can only conform to a certain standard shape (such as a perfect circle). It cannot adapt to non-standard ring wearing areas 2 such as ovals or irregular shapes, resulting in gaps between the inner ring 102 of the ring and the skin, affecting the user's wearing comfort and the accuracy of measurement data.

[0043] Flexible materials are also soft, skin-friendly, and non-irritating, which can disperse the pressure of the smart ring 1 on the skin and avoid discomfort caused by local pressure (such as marks or poor blood circulation). In contrast, rigid materials (such as metals and hard resins) have high hardness and low elastic modulus, and can only form point or line contact with the skin. The pressure is concentrated in a local area, and long-term wear can cause obvious pain and even affect the movement of the ring wearing area 2.

[0044] In some embodiments of this application, if the smart ring 1 integrates optical (photoplethysmography) and electrical (bioelectrical impedance) sensors, the sensors need to be in close contact with the skin to ensure measurement accuracy. A flexible inner ring can keep the sensor in close contact with the skin through its own deformation, avoiding signal attenuation and data fluctuations caused by loosening. On the other hand, a gap between a rigid inner ring and the skin will result in insufficient contact between the sensor and the skin, making the optical signal susceptible to interference from ambient light and increasing the conduction resistance of the electrical signal, ultimately leading to inaccurate measurement data.

[0045] In some embodiments of this application, the inner ring 102 of the ring can be made of liquid silicone. Liquid silicone is a two-component polymer material composed of organosilicon compounds and catalysts. It has excellent elastic deformation capabilities, adapts to personalized qualitative core needs, and is skin-friendly, safe, and comfortable to wear, making it suitable for long-term wear scenarios. The liquid silicone inner ring has good skin-friendliness and initial sealing properties. Combined with the rigid or semi-rigid support formed after internal curing, it enables the smart ring 1 and the ring wearing part 2 to achieve a tight, airtight, and watertight fit, greatly improving the signal quality of sensors (such as circuit films, inductive films, and electrode films).

[0046] In some embodiments of this application, the first chamber 13 may contain a first filler, and the second chamber 14 may contain a second filler. Both the first and second fillers can be colloids. The colloids can be transparent. Both the first and second fillers can be liquid colloids.

[0047] In some embodiments of this application, the first filler may be a liquid resin. The second filler may be a liquid curing agent. Both the liquid resin and the liquid curing agent have excellent fluidity in their unmixed state. When the user wears the smart ring 1, the liquid resin and the liquid curing agent, after mixing, can instantly fill all the tiny gaps between the inner ring 102 of the ring and the ring wearing part 2 under the pressure and gravity of the ring wearing part 2, without the need for additional external force.

[0048] In some other embodiments of this application, the first filler may be a solid powder, and the second filler may be a liquid colloid. Alternatively, the first filler may be a liquid colloid, and the second filler may be a solid powder.

[0049] Both liquid resin and liquid curing agent have the physical properties of low viscosity and high fluidity, which are precisely matched with the structural design of the annular inner cavity and the connection logic after the isolation membrane is damaged.

[0050] In some embodiments of this application, the smart ring may include a data acquisition module. The acquisition module may be disposed within the annular cavity and used to acquire physiological signals from the ring wearer. These physiological signals may include data such as heart rate, blood oxygen saturation, and pulse waveform.

[0051] In some embodiments of this application, the inner ring 102 can be made of a transparent, flexible material. When the acquisition module acquires physiological signals, light or electrical signals can penetrate the inner ring 102, ensuring the effectiveness of signal transmission by the acquisition module and laying the foundation for accurate measurement.

[0052] In some embodiments of this application, the isolation component 12 can be used to divide the annular cavity into a first chamber 13 and a second chamber 14. The function of the isolation component 12 varies depending on the state of the smart ring 1. Specifically, if the smart ring 1 is not worn, the isolation component 12 can be used to divide the annular cavity into a first chamber 13 and a second chamber 14; if the smart ring 1 is worn, the isolation component 12 can also be used to connect the first chamber 13 and the second chamber 14.

[0053] After the first and second fillers are mixed, they need to flow, fill, and solidify under the contour constraints of the ring wearing area 2. During this process, the fillers themselves will undergo slight volume changes, and the ring wearing area 2 may experience minor displacement due to slight movements. Flexible materials can absorb these volume changes and displacements through their own elastic deformation, ensuring that the fillers always adhere tightly to the skin. The final solidified liner matches the contour of the ring wearing area 2 100%. Rigid materials, on the other hand, cannot produce any effective deformation, and the problem of the smart ring 1 not fitting tightly to the skin and causing discomfort for the user still exists.

[0054] In some embodiments of this application, the control module 11 may be disposed in the annular inner cavity and connected to the isolation component 12. The control module 11 may be used to control the isolation component 12 to connect the first chamber 13 and the second chamber 14. When the first chamber 13 and the second chamber 14 are connected, the first filler and the second filler fuse and react chemically in the connected annular inner cavity to form a cured liner adapted to the ring wearing part 2. The ring wearing part 2 may be a finger.

[0055] In some embodiments of this application, the isolation component 12 may include an isolation membrane. The isolation membrane is the core isolation carrier of the isolation component 12, and it undergoes a predictable physical state change (such as melting) at a preset temperature threshold, thereby releasing the physical isolation between the first chamber 13 and the second chamber 14 and providing a channel for the mixing of the first filler and the second filler.

[0056] In the untriggered state, the insulating membrane completely separates the first chamber 13 and the second chamber 14, ensuring that the first filler and the second filler remain physically isolated during storage, transportation, and initial wearing, thus maintaining their stability. In the triggered state, the insulating membrane receives heat energy transferred from the heating element, undergoes a physical state change at a set temperature, and forms an effective channel connecting the first chamber 13 and the second chamber 14.

[0057] The set temperature must be significantly higher than human body temperature and ambient temperature (typically less than 45°C) to prevent accidental triggering. At the same time, the set temperature must be low enough to be achieved within a few seconds to a dozen seconds using the ring's built-in miniature, low-power heating element without posing a risk of burns to the user or excessively draining the smart ring's battery 16.

[0058] Therefore, in some embodiments of this application, the set temperature can be between 50°C and 80°C. The set temperature can also be other values.

[0059] In some embodiments of this application, the separator must have good mechanical and barrier properties. At room temperature, the separator must have sufficient strength and flexibility to withstand the stress during production, transportation and wearing, and be able to perfectly block the mutual permeation of the first filler and the second filler.

[0060] In some embodiments of this application, the separator must also be biocompatible and chemically inert. The separator must not react chemically with the first filler or the second filler, and must not release any harmful substances during long-term contact.

[0061] In some embodiments of this application, the release liner may be adhesive to the inner ring 102 (liquid silicone), forming a strong interfacial bond during the molding process of the release liner and the liquid silicone, preventing it from detaching from the edges under the pressure of the colloid injection.

[0062] In some embodiments of this application, the separator may include a thermoplastic separator. The thermoplastic separator may be polycaprolactone, with a melting point of approximately 60°C, biodegradable, and exhibiting excellent flexibility. The thermoplastic separator may also be low-density polyethylene, which offers good barrier properties and is cost-effective. The thermoplastic separator may also be a specific type of polyurethane or copolyester, and its melting point can be adjusted through molecular design. The thermoplastic separator may also be made of other materials. The thermoplastic separator possesses the core physical characteristic of being easily damaged by heat, thus precisely matching the triggering method of the heating element.

[0063] In some embodiments of this application, the separator may include a thin film made of an electrolytic material, i.e., an electrolytic separator. An electrolytic separator is a thin-film element made of a polymer substrate containing ionic conductive components. Under the excitation of a preset electrical signal, it undergoes chemical bond breakage through an electrochemical oxidation-reduction reaction, decomposing from a solid film into soluble products or low-molecular-weight gases, thereby losing its separator function. The electrolytic material possesses the core physical characteristic of being easily destroyed by heat, thus precisely matching the triggering method of the heating element.

[0064] When not receiving an electrical signal, the electrolytic separator, thanks to its structural integrity, tightly binds to the inner ring 102 of the ring, dividing the annular cavity into a first chamber 13 and a second chamber 14, ensuring that the first and second fillers do not mix during storage, transportation, and initial wear. When the electrolytic separator receives an electrical signal transmitted by a conductive element, it completes electrochemical decomposition, forming a connecting channel that connects the first chamber 13 and the second chamber 14.

[0065] In some embodiments of this application, the electrolytic separator can be a polyvinyl chloride electrolytic membrane, a polyethylene oxide electrolytic membrane, or an ion exchange membrane, etc. The electrolytic separator can also be made of other material types.

[0066] In some embodiments of this application, the isolation component 12 may include a heating element. The heating element is a core component for achieving heat output; driven by the control module 11, it is an electronic component that efficiently converts electrical energy into heat energy and directionally transfers it to the isolation membrane to melt it. The heating element can be electrically connected to the control module 11, which controls whether the heating element operates and its operating power.

[0067] Therefore, by combining the isolation membrane with the contact heating element, the control module can precisely drive the heating element to work and use heat to directly melt the isolation membrane (instead of relying on complex mechanical structures or electrochemical reactions), ensuring rapid and stable connection between the first chamber and the second chamber.

[0068] The heating element can receive electrical signals output by the control module 11 and convert electrical energy into heat energy. Through physical contact or near-field radiation, the heating element can accurately transfer heat energy to key areas of the insulating membrane (such as the middle of the insulating membrane), ensuring that the insulating membrane is heated evenly. The heating power and heating time of the heating element can be precisely controlled by the control module 11 to avoid overheating and damaging the structure of the smart ring 1 or burning the user's skin.

[0069] In some embodiments of this application, the heating element may include a nickel-chromium heating wire, which has the characteristics of high resistivity, high temperature resistance, and strong oxidation resistance. The heating element may also include a ceramic heating element, which has the characteristics of high thermal conductivity and good insulation. Other types of elements may also be used as the heating element.

[0070] In some embodiments of this application, the heating element may be in contact with the insulating membrane. The control module 11 may be used to control the heating element to heat the insulating membrane, thereby connecting the first chamber 13 and the second chamber 14.

[0071] In some embodiments of this application, when the separator includes a thermoplastic separator, the control module 11 can also be used to control the heating element to melt the thermoplastic separator so that the first chamber 13 and the second chamber 14 are connected.

[0072] In some embodiments of this application, the thermoplastic separator can be an annular film, the inner liner of which can precisely match the annular cavity, i.e., the outer diameter of the annular film can be equal to the inner diameter of the annular cavity, to ensure complete coverage of the cross-section of the annular cavity without leakage gaps. The thickness of the thermoplastic separator can be 20 to 100 micrometers. If the thermoplastic separator is too thick, it will be difficult to melt, while if the thermoplastic separator is too thin, it will be easily damaged and have poor barrier properties. The thickness of the thermoplastic separator can also be other values.

[0073] In some embodiments of this application, during liquid silicone injection molding, a pre-cut film can be placed as an insert into the mold. The liquid silicone cures around the edges of the film, forming a mechanical interlock and chemical bond, thereby creating a reliable first chamber 13 and a second chamber 14 separated by the film inside the smart ring 1.

[0074] In some embodiments of this application, the control module 11 can be used to control the conductive element to output a preset electrical signal to the insulating film for excitation, so that the film made of electrolytic material undergoes electrochemical decomposition, thereby connecting the first chamber 13 and the second chamber 14.

[0075] In some embodiments of this application, the isolation component 12 may further include a miniature electrically controlled valve. The miniature electrically controlled valve is a miniature control element that opens / closes the channel by driving an internal valve core with an electrical signal. The control module 11 outputs an electrical signal to drive the opening and closing of the miniature electrically controlled valve, thereby achieving controllable communication between the first chamber 13 and the second chamber 14. The initial state of the miniature electrically controlled valve is normally closed, the fluid channel is completely closed, and the first chamber 13 and the second chamber 14 are physically isolated.

[0076] In some embodiments of this application, the control module 11 may include a circuit board 15, specifically a printed circuit board assembly (PCBA). The circuit board 15 may be pre-assembled and fixed inside the outer ring 101 of the ring.

[0077] In some embodiments of this application, a control chip, a communication module, and a heating element may be integrated on the circuit board 15. The control chip is a microcontroller integrating computation, logic judgment, and signal output functions. Its core function is to receive external commands (such as trigger signals from a mobile app) transmitted by the communication module, parse them, and output drive signals to control the heating element. The communication module is a component that enables wireless communication between the smart ring 1 and external devices (such as mobile phones or tablets). Its core function is to receive adapted trigger commands sent by external devices and transmit them to the control chip; it can also provide feedback on the working status of the smart ring 1 (such as successful triggering or low battery), thereby achieving bidirectional communication. The heating element, driven by the control chip, converts electrical energy into heat energy to provide trigger energy for the isolation component 12. Its core function is to accurately output preset heat, causing physical changes (melting, deformation) in the isolation component 12.

[0078] In some embodiments of this application, the heating element fails after a single operation and cannot be repeatedly driven to heat.

[0079] In some embodiments of this application, the smart ring 1 may further include a battery 16, which is disposed within the annular inner cavity and is used to power the circuit board 15. The battery 16 is an energy storage element that provides a stable DC power supply to all circuit boards 15 and all electronic components. Its core function is to output a stable voltage to meet the power consumption requirements of the control module 11 for functions such as isolation component 12, communication, and monitoring.

[0080] In some embodiments of this application, the battery 16 may be located in a different chamber from the circuit board 15. For example, the battery 16 may be located in a first chamber 13, and the circuit board 15 may be located in a second chamber 14. Alternatively, the battery 16 may be located in the second chamber 14, and the circuit board 15 may be located in the first chamber 13.

[0081] In addition, this application also proposes a method for adjusting the inner lining of the smart ring 1, and the method can be applied to the smart ring 1 mentioned above.

[0082] Figure 3 A flowchart illustrating the adjustment of the inner lining of a smart ring according to an embodiment of this application is shown. Figure 3 As shown, the method may include: S310 sends an adjustment command to the smart ring via an external device. The adjustment command indicates that the inner lining of the smart ring needs to be adjusted. S320, if the smart ring receives an adjustment command, it controls the isolation component to connect the first chamber and the second chamber.

[0083] Specifically, users can send adjustment commands to the smart ring via a mobile app. These commands initiate adjustments to the ring's inner lining. After receiving and verifying the command, the smart ring's control module activates the isolation component, releasing the physical separation between the first and second chambers and allowing them to connect. The first and second fillers within the two chambers mix under the constraint of the ring's wearing area, undergoing a chemical reaction to solidify and form a cured inner lining that perfectly conforms to the ring's wearing area, thus completing the personalized adjustment of the smart ring's inner lining. The entire lining customization process requires no professional expertise or complex operations; users simply need to wear the smart ring and trigger the adjustment with a single click via the mobile app, providing a user-friendly experience. This simple and reliable method achieves personalized inner lining adaptation for the smart ring while ensuring controllability and a positive user experience.

[0084] Figure 4 A flowchart illustrating the adjustment of the inner lining of a smart ring, according to another embodiment of this application, is shown. Figure 4 As shown, before the smart ring receives the adjustment command, the method may further include: S410 detects whether the smart ring is worn on the wearing area; S420, when it detects that the smart ring is worn on the wearing area, sends an adjustment command to the smart ring through an external device.

[0085] The following sections will elaborate on S410-S420 respectively.

[0086] In S410, in some embodiments of this application, multiple miniature pressure sensors can be evenly distributed on the inner wall of the inner ring structure of the ring to detect whether the smart ring is worn on the wearing part of the ring.

[0087] In some other embodiments of this application, an infrared emitting tube and an infrared receiving tube can be respectively arranged on both sides of the annular inner cavity, and an infrared photoelectric sensor can be used to detect whether the smart ring is worn on the wearing part of the ring.

[0088] In the S420, once the external device receives a signal indicating that the smart ring is ready to be worn, a pop-up window can be displayed on the external device prompting "Inner liner adjustment can be started". After the user confirms the operation, an adjustment command is generated and sent to the smart ring.

[0089] Therefore, by detecting wear beforehand, the adjustment command is ensured to be sent only when the ring is actually worn, preventing accidental damage to the isolation component and mixing of fillers when not worn, thus avoiding waste of adhesive and ineffective structural loss.

[0090] Figure 5 A flowchart illustrating the adjustment of the inner lining of a smart ring, according to another embodiment of this application, is shown. Figure 5 As shown, the control isolation assembly to connect the first chamber and the second chamber includes: S510 drives the built-in heating element to work, so as to melt the isolation membrane disposed between the first chamber and the second chamber, thereby connecting the first chamber and the second chamber; wherein the heating element is in contact with the isolation membrane.

[0091] In S510, the heating element can be built into the smart ring, making physical contact with the insulating membrane. When the smart ring receives an adjustment command from an external device, the control module outputs a drive signal to the heating element, causing it to melt the insulating membrane positioned between the first and second chambers. After melting, the insulating membrane fuses with the filling material within the chambers, connecting the first and second chambers.

[0092] Therefore, the precise triggering method of melting the isolation membrane by contact heating ensures the reliability and efficiency of chamber connectivity, providing stable support for subsequent personalized adaptation.

[0093] Figure 6 A flowchart illustrating the adjustment of the inner lining of a smart ring, according to another embodiment of this application, is shown. Figure 6 As shown, the method may also include: S610, after the insulating film melts, the first filler and the second filler are mixed together. The mixed filler is made to conform to the contour of the ring wearing part based on its flow, and is cured by chemical reaction to form a cured liner that fits the ring wearing part.

[0094] In S610, after the release membrane melts, the first filler, which is the liquid resin, and the second filler, which is the liquid curing agent, mix with each other. The mixing process does not require an additional power device and can be achieved by natural driving force, such as the slight movement of the ring wearing part, which causes slight deformation of the inner silicone ring of the ring, indirectly promoting the flow and mixing of the liquid resin and the liquid curing agent.

[0095] During the flow and filling process, the hybrid filler is constantly constrained by the elastic structure of the inner ring. The inner silicone ring directly contacts the user's finger skin and has excellent skin-friendliness and conformity. Its shape naturally conforms to the contour of the finger, forming a flexible mold. As a liquid substance, the hybrid filler can perfectly adapt to the internal shape of the flexible mold—the thickness variations, contour curvature, and skin texture (such as fingerprint grooves) of the ring wearing area are all transmitted to the hybrid filler through the inner silicone ring. This allows the hybrid filler to adhere tightly to the inner wall of the inner silicone ring during the flow process, replicating the three-dimensional contour of the ring wearing area and achieving a 100% personalized match.

[0096] After the liquid resin is mixed with the liquid curing agent, it undergoes a chemical reaction at room temperature to cure, ultimately forming a cured lining that fits the part of the ring to be worn.

[0097] Thus, through a complete process of filling material mixing, flow bonding, and chemical reaction curing, the smart ring achieves precise and personalized fit to the wearing area, while enhancing the stability of the fit and the synergy of functions.

[0098] Figure 7 A flowchart illustrating the adjustment of the inner lining of a smart ring, according to another embodiment of this application, is shown. Figure 7 As shown, after forming a cured inner liner that fits the wearing area of ​​the ring, the method may further include: S710, the control module sends a feedback signal to the external device, the feedback signal indicating that the inner lining of the smart ring has been cured.

[0099] In the S710, after the solidified inner liner has been formed and effectively fitted, the control module immediately sends a feedback signal to the external device. The feedback signal can indicate that the inner liner of the smart ring has been solidified and can be communicated to the ring wearer through visual interaction, forming a complete closed loop.

[0100] Therefore, signal feedback enables a closed-loop process for adjusting the lining, enhancing the controllability of the adaptation process, user experience, and functional synergy.
