Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of decompression products, in particular to a decompression ring and a material thickness determination method and system thereof. BACKGROUND

[0002] With the acceleration of modern social life rhythm and the increasing work pressure, people's demand for psychological adjustment and emotional release in daily life is increasing. In order to relieve negative emotions such as anxiety and tension, various decompression products have emerged as the times require, and gradually become common auxiliary tools in people's daily life. This kind of decompression product provides physical interaction mode of operable, touchable or repeatable action, helps users to divert attention, relax nerves and improve concentration, and is widely used in office, study and other scenes.

[0003] The common decompression products on the market mainly include fingertip gyroscopes, pinch toys (silicone foam toys) and the like. Although these decompression products can help users relieve stress to some extent, they still have obvious shortcomings. For example, the fingertip gyroscope is too large to be carried around; the pinch toy is soft in touch, but lacks operation feedback, has limited decompression effect, and some materials have problems such as aging and chipping. In addition, the above decompression products do not have a wearing function, and cannot be used "anytime, anywhere", which limits the flexibility of their use scenarios.

[0004] In order to solve the above problems, finger ring type decompression products have appeared on the market, which have the advantages of small size, easy to carry, strong concealment, convenient to use, etc., and are particularly suitable for use in meetings, learning and other occasions that require quietness and concentration. The existing finger ring type decompression products usually adopt a double-layer structure in which the outer ring is sleeved on the peripheral part of the inner ring, and there is a component between the inner ring and the outer ring that plays a friction role. The user rotates the outer ring by rubbing to achieve the purpose of decompression. However, this method can only achieve the relative displacement of the outer ring and the inner ring, lacks the friction and frustration between them, has poor decompression effect, and affects the user experience.

[0005] Therefore, the prior art (utility model patent with authorization announcement number CN220513422U) discloses a decompression ring, which comprises an inner ring assembly, a rotating assembly, a magnetic adjusting assembly and a magnetic fixing piece. The magnetic fixing piece is installed in the inner ring assembly, the magnetic adjusting assembly is installed in the rotating assembly, and the rotating assembly is rotationally connected to the inner ring assembly. The rotating assembly is provided with a plurality of mounting parts, and the magnetic adjusting assembly comprises a plurality of magnetic units. At least one magnetic unit is installed in each mounting part. When the rotating assembly rotates around the inner ring assembly, different resistances are generated, thereby solving the technical problem that the above-mentioned finger ring type decompression product can only achieve the relative displacement of the outer ring and the inner ring, and lacks the friction and frustration between them, and improving the decompression effect.

[0006] However, the above prior art still has the following problems in actual use:

[0007] 1. The inner ring assembly for installing the magnetic fixing part and the rotating assembly for installing the magnetic adjusting assembly are both composed of multiple parts, the structure is relatively complex, is easy to be damaged during use, and has a high maintenance cost.

[0008] 2. The inner ring assembly and the rotating assembly are rotationally connected through bearings. On the one hand, the size of the existing bearings is large, which leads to a large overall size of the decompression ring, and the user experience is affected. On the other hand, small-size high-quality bearings are expensive, which leads to a high cost of the decompression ring, cannot meet the low-cost demand of the decompression ring application scene, and is not conducive to improving market competitiveness. SUMMARY

[0009] The purpose of the present application is to provide a decompression ring and a material thickness determination method and system thereof, which partially solve or alleviate the above-mentioned deficiencies in the prior art, can simplify the structure of the decompression ring, reduce its size, ensure the service life of the decompression ring, and improve the user experience.

[0032] The second aspect of the application provides a material thickness determination system for a decompression ring, comprising:

[0040] Preferably, as an improvement, the decompression ring further comprises a bottom support ring fixedly inserted in the fixed inner ring, and the bottom support ring is integrated with a plurality of sensors for collecting physical data and physiological data of the user, the physical data including dialing pressure and dialing frequency, and the physiological data including at least one of heart rate, blood pressure and body temperature.

[0041] The beneficial technical effects of the present application are:

[0042] In one aspect, the structure of the decompression ring is improved, and the following technical effects can be achieved:

[0043] 1. Highly simplified structure, improved reliability: The present application discards the complex structure of the prior art, such as relying on bearings, multi-component magnetic adjustment mechanism, and adopts a simple design of fixed inner ring and movable outer ring directly sliding together, significantly reducing the number of parts and simplifying the assembly process. This structure avoids failures caused by bearing damage, magnetic component loosening, etc., greatly improving the structural stability and long-term reliability of the product.

[0044] 2. Reduce manufacturing cost, improve market competitiveness: The present application does not need to use high-precision small-size bearings and complex magnetic adjustment components, effectively reducing the procurement and processing cost of raw materials. At the same time, the simplified structure also reduces the assembly time and quality inspection difficulty, further compresses the production cost, makes the product more easily to realize the scale production, enhances the price competitiveness in the consumer market.

[0045] 3. Enhance decompression interaction experience: The present application embeds fixed magnetic parts and movable magnetic parts on the fixed inner ring and the movable outer ring respectively, uses the attraction and repulsion between magnetic poles to form regular "jerking" or "paragraph" feeling during rotation, simulates rhythmic operation feedback, significantly improves the operation interest and heart decompression effect of the user, which is better than the traditional design relying only on friction or smooth rotation.

[0046] On the other hand, the self-lubricating material thickness determination method provided by the present application can achieve the following technical effects:

[0047] 1. Achieve precise balance between service life and size: The present application provides a systematic self-lubricating material thickness determination method, which comprehensively considers the friction coefficient, user dialing pressure, frequency and expected service life, calculates the "calculated thickness" that meets the durability requirements through the wear rate model; combined with the "expected thickness" of the user's wearing comfort, a more optimal "reference thickness" is determined. This method scientifically solves the technical contradiction between miniaturization and long service life, ensuring that the product is both lightweight and portable and has a long service life.

[0048] 2. Improve the personalization level of decompression rings and realize group customization design: The thickness determination method of the present application introduces a multi-dimensional user clustering analysis mechanism, breaking through the limitations of the traditional "general design" mode, and realizing the transition from "function-oriented" to "user demand-oriented".

[0049] Specifically, based on the objective characteristics (such as occupation category, health status) and subjective preferences (such as anxiety level, dialing preference) of users, the present application divides users into several groups with common behavior patterns. For example, high-intensity mental workers (such as programmers, doctors) usually have high anxiety levels and high dialing frequencies; while students may prefer light resistance and high frequency dialing. Thus, the typical dialing pressure, dialing frequency and expected service life of different groups are calculated respectively, the thickness parameters of self-lubricating materials are dynamically adjusted, and the customization design at the group level is realized, which can significantly improve the personalization adaptation ability of decompression rings and meet the individual needs of different user groups.

[0050] Compared with the "individual-level personalization" scheme commonly used in the prior art, the present application adopts the design concept of "replacing individuals with groups", which has the following significant advantages: avoiding individual dialing interference, improving the stability and accuracy of clustering results.

[0051] The "personalization" in the prior art often emphasizes modeling for each user individually, relies on a large amount of individual behavior data for clustering analysis, and even needs to use AI algorithms for complex prediction. However, individual state has high volatility and is easily affected by short-term emotions, environment, physical condition and other factors, resulting in unstable clustering results. For example, a user may be misjudged as a "high-pressure user" due to high-intensity dialing of the decompression ring caused by emotional excitement, resulting in a deviation in the design of the thickness of the self-lubricating material.

[0052] On the contrary, the present application abandons the idealized path of "individual accurate profiling", and instead adopts a group division strategy based on discrete labels, using stable and interpretable macro features such as occupation, health status, anxiety level to construct user profiles. These features reflect the typical state of the user over a long time scale, rather than instantaneous behavior, and have stronger stability and representativeness. For example, dividing the anxiety level into high, medium and low levels can more stably reflect the psychological load characteristics of the user than directly using the "heart rate variability" measured at a certain time, avoiding misjudgment due to accidental factors.

[0053] The application adopts hierarchical and discrete group characteristics for grouping, which is similar to "using hierarchical evaluation instead of specific scores" to reflect learning level - although individual test scores may deviate from the true level due to abnormal performance, but by evaluating their long-term performance and dividing into A / B / C levels, it can more stably and accurately reflect their overall ability. Similarly, the application constructs a user portrait by stable social attributes and psychological state tags, effectively filters transient behavior noise, and ensures that the clustering result reflects the user's typical use mode rather than accidental state, significantly improving the scientificity and reliability of personalized design.

[0054] In addition, compared with the method of simply relying on original use data (such as dial pressure, dial frequency, etc.) for unsupervised clustering, the present scheme uses objective features and subjective preferences with clear semantics as clustering conditions, which can realize the interpretability and production feasibility of user grouping, avoid the problem of "excessive clustering", and the specific description is as follows:

[0055] (1) Improve the interpretability and business relevance of user groups: objective features such as occupation category (such as programmer, teacher, medical staff), health status (such as anxiety patients, sleep disorder patients) have clear social and medical significance, and subjective features such as anxiety level and dial preference degree directly reflect the user's psychological state and use motivation. The user groups formed based on these features naturally have clear labels and portraits, and this grouping result is easy to be understood and applied by product design, marketing and sales teams, which can directly guide product function definition (such as configuring higher wear-resistant thickness in high-pressure groups), appearance style positioning (such as designing more lively for students), and channel strategy (such as promoting to job seekers), realizing the close connection between technical scheme and business landing.

[0056] (2) Effectively control the number of user groups to avoid "fragmentation" leading to unquantifiable production: if only based on continuous behavior data (such as dial pressure, dial frequency) for unsupervised clustering, it is easy to form too many and too detailed user groups due to slight differences, leading to too many material thickness specifications, increased mold cost, difficult inventory management, and increased production complexity. The present scheme introduces limited and discrete features as clustering dimensions, which naturally limits the number and complexity of clustering results, and finally forms a moderate number of user groups that can meet the differentiated needs of mainstream user groups and have the feasibility of mass production, truly realizing the balance between "personalization" and "batch production", and avoiding the cost out-of-control problem caused by "over-customization".

[0057] Further, the original clustering is only based on objective features (such as occupation category, health status) and subjective preferences (such as anxiety level, dialing preference), which belongs to "indirect inference" of user usage behavior. After introducing the second subjective group feature (such as dialing pressure, dialing frequency and expected service life), the actual or expected usage behavior data of the user is directly included in the clustering dimension, which makes the clustering result no longer dependent on "speculation", but is based on real behavior patterns, significantly improving the scientificity and accuracy of user group division. For example, two users with the same anxiety level will be divided into different groups if one is used to "heavy pressure and slow dialing" and the other is used to "light touch and fast rotation", so as to match different material thickness schemes.

[0058] Further, the average, median and mode are different statistics suitable for different data distribution scenarios. In real user data, there are often outliers or extreme behaviors (such as overuse, misuse, etc.). If only the average is used, the calculated wear rate and thickness may be higher, resulting in material waste. If the median or mode is used, the influence of outliers can be effectively suppressed, making the material thickness design closer to the normal use scenario of most users. By flexibly selecting or combining the three statistical methods, the "group typical value" determined by the application can more truly represent the mainstream behavior of the group, enhancing the robustness of parameter design and avoiding the deviation caused by a single indicator.

[0059] 3. Optimize user experience and avoid overdesign or insufficient performance: By establishing a nonlinear correspondence between the gap between the self-lubricating material and the fixed inner ring or sliding outer ring and the user experience threshold, and combining the user experience threshold for thickness correction, the application can effectively avoid the problem of early wear caused by excessive thickness of the self-lubricating material or excessive thickness of the self-lubricating material, ensuring that the decompression ring achieves the best balance in terms of visual, tactile and operational feeling.

[0075] Embodiment One:

[0076] The present embodiment provides a decompression ring, as shown in FIGS. 1-3, comprising a movable outer ring 100 and a fixed inner ring 200, the movable outer ring 100 is nested on the outer peripheral wall of the fixed inner ring 200, and the inner peripheral wall of the movable outer ring 100 is in clearance fit with the outer peripheral wall of the fixed inner ring 200, so that the movable outer ring 100 can rotate around the fixed inner ring 200. Figure 1 、 Figure 2 and Figure 3 Specifically, the outer peripheral wall of the fixed inner ring 200 is provided with an annular mounting groove 201 in the circumferential direction, the width of the mounting groove 201 matches the width of the movable outer ring 100, so that the movable outer ring 100 can be embedded into the mounting groove 201; and the inner peripheral wall of the movable outer ring 100 is in clearance fit with the bottom of the mounting groove 201, so that the movable outer ring 100 can rotate around the fixed inner ring 200.

[0077] Specifically, the outer peripheral wall of the fixed inner ring 200 is provided with an annular mounting groove 201 in the circumferential direction, the width of the mounting groove 201 matches the width of the movable outer ring 100, so that the movable outer ring 100 can be embedded into the mounting groove 201; and the inner peripheral wall of the movable outer ring 100 is in clearance fit with the bottom of the mounting groove 201, so that the movable outer ring 100 can rotate around the fixed inner ring 200.

[0078] The contact surface of the movable outer ring 100 and the fixed inner ring 200 is provided with a self-lubricating material, in the present embodiment, the inner peripheral wall of the movable outer ring 100 is provided with a hard self-lubricating material. Specifically, the inner peripheral wall of the movable outer ring 100 is provided with an annular movable groove 101 in the circumferential direction, and the self-lubricating material is filled in the movable groove 101.

[0079] The thickness of the self-lubricating material is determined based on its friction coefficient with the fixed inner ring 200. Specifically, the self-lubricating material is iglidur J type plastic or a self-lubricating material made of phosphor bronze, which can maintain good lubrication without lubricating oil, and the user does not need to maintain the ring, ensuring a good user experience.

[0080] The fixed inner ring 200 is made of hard non-self-lubricating material; the hard non-self-lubricating material can be titanium alloy, stainless steel, crystal, and glass ceramic. It should be noted that those skilled in the art can coat the surface of the fixed inner ring 200 with a material to enhance the tactile sensation according to the actual user experience requirements based on the above non-self-lubricating material. The coating material can be plastic, beeswax, etc.

[0081] In some embodiments, the inner peripheral wall of the movable outer ring 100 is also coated with self-lubricating material outside the movable groove 101.

[0082] In some embodiments, the two side walls of the movable outer ring 100 are also coated with self-lubricating material.

[0083] Coating the inner peripheral wall of the movable outer ring 100 outside the movable groove 101 and / or the two side walls of the movable outer ring 100 with self-lubricating material can increase the contact area between the self-lubricating material and the fixed inner ring 200, which is beneficial to improve the smoothness of the rotation of the movable outer ring 100 relative to the fixed inner ring 200, thereby improving the user experience.

[0084] In some embodiments, the entire movable outer ring 100 is made of self-lubricating material.

[0085] Making the entire movable outer ring 100 directly of self-lubricating material can reduce the thickness of the movable outer ring 100, thereby further reducing the overall thickness of the decompression ring, which is beneficial to improve the user experience.

[0086] In other embodiments, the outer peripheral wall of the fixed inner ring 200 is provided with hard self-lubricating material, and the movable outer ring 100 is made of hard non-self-lubricating material. Specifically, the bottom of the mounting groove 201 is provided with an annular fixed groove 202 along the circumference of the fixed inner ring 200, and the self-lubricating material is filled in the fixed groove 202.

[0087] In some embodiments, the bottom of the mounting groove 201 is also coated with self-lubricating material outside the fixed groove 202.

[0088] In some embodiments, the two side walls of the mounting groove 201 are also coated with self-lubricating material.

[0089] The self-lubricating material is arranged at the bottom of the mounting groove 201 at a position other than the fixed recess 202 and / or the two side walls of the mounting groove 201, so that the contact area of the self-lubricating material with the movable outer ring 100 is increased, the smoothness of the rotation of the movable outer ring 100 relative to the fixed inner ring 200 is improved, and the user experience is improved.

[0090] In some embodiments, the fixed inner ring 200 is entirely made of self-lubricating material.

[0091] The entire fixed inner ring 200 is directly made of self-lubricating material, which can reduce the thickness of the fixed inner ring 200, thereby further reducing the overall thickness of the decompression ring, and improving the user experience.

[0092] In other embodiments, the inner peripheral wall of the movable outer ring 100 and the outer peripheral wall of the fixed inner ring 200 are both provided with self-lubricating material. However, this scheme can improve the rotation smoothness and service life of the decompression ring, but will significantly increase the manufacturing cost, which is not conducive to the promotion of the decompression ring.

[0093] The present application sets annular grooves on the movable outer ring 100 and / or the fixed inner ring 200 and embeds self-lubricating material, which can overcome the defects of self-lubricating material such as easy wear, peeling, uneven lubrication, etc., and achieve the technical effects of more stable lubrication, stronger wear resistance, smoother rotation, and longer service life. At the same time, the present application can improve the structural reliability and manufacturing flexibility of the product, which is significantly superior to the simple surface coating method. The specific description is as follows:

[0094] (1) Improve lubrication stability and uniformity, and avoid lubrication failure. The self-lubricating material directly coated on the outer peripheral wall of the fixed inner ring 200 is continuously rubbed by the movable outer ring 100 during long-term use, which can cause local wear, peeling or uneven distribution of the self-lubricating material, especially at the edge or stress concentration area, thereby causing a decrease in lubrication performance and causing jamming and abnormal noise. The present application sets movable grooves 101 on the inner peripheral wall of the movable outer ring 100 and fills them with self-lubricating material, or sets fixed grooves 202 on the bottom of the mounting groove 201 of the fixed inner ring 200 and fills them with self-lubricating material, which "embeds" the self-lubricating material in the groove structure, forming a "inlaid" lubrication structure, which can effectively limit the horizontal movement and peeling of the self-lubricating material, so that it can release lubricating components more stably and durably during friction, thereby significantly improving the uniformity and continuity of lubrication, and avoiding lubrication failure caused by material peeling.

[0095] (2) Prolong the service life of the product and improve the wear resistance. The self-lubricating material is directly coated or laid on the surface, and the bonding force with the base body is limited, which is easy to be quickly worn out due to repeated friction, resulting in a relatively short service life of the product. The self-lubricating material of the present application is limited in the groove, which is equivalent to being protected by the "enclosure" of the base material, and can slow down the rate of direct exposure to the friction interface. Even if the surface material is gradually worn out, the self-lubricating material in the groove can continue to supplement, realizing long-acting and slow-release lubrication. Therefore, the wear resistance of the overall structure of the present application is significantly enhanced, so that the service life of the decompression ring is greatly prolonged.

[0096] (3) Enhance the structural reliability and manufacturing flexibility. The present application sets the self-lubricating material in the groove, avoiding the process difficulty (such as uneven thickness, poor adhesion) brought by large-area laying, which is beneficial to improve the manufacturing yield and consistency. And the present application provides various implementation modes (such as only groove filling, groove + side wall laying, whole self-lubricating material, etc.), which can flexibly select material combination and processing technology according to cost and performance requirements, enhancing the scalability and adaptability of the design.

[0097] In some embodiments, the inner circumferential wall of the movable outer ring 100 is embedded with a movable magnetic member 102 (also referred to as a first magnetic member), and the outer circumferential wall of the fixed inner ring 200 is embedded with a fixed magnetic member 203 (also referred to as a second magnetic member). During the rotation of the movable outer ring 100 around the fixed inner ring 200, the movable magnetic member 102 and the fixed magnetic member 203 switch between the in-position and out-of-position states, and the movable magnetic member 102 and the fixed magnetic member 203 attract each other when they are in the in-position state. The movable magnetic member 102 and / or the fixed magnetic member 203 are embedded in the self-lubricating material.

[0098] Specifically, when the inner circumferential wall of the movable outer ring 100 is provided with movable grooves 101 circumferentially, the movable magnetic member 102 is fixedly embedded in the movable grooves 101, and the self-lubricating material is filled around the movable magnetic member 102; when the inner circumferential wall of the movable outer ring 100 is not provided with movable grooves 101, movable connection grooves are provided on the inner circumferential wall of the movable outer ring 100, and the movable magnetic member 102 is fixedly embedded in the movable connection grooves. When the outer circumferential wall of the fixed inner ring 200 is provided with fixed grooves 202, the fixed magnetic member 203 is fixedly embedded in the fixed grooves 202, and the self-lubricating material is filled around the fixed magnetic member 203; when the outer circumferential wall of the fixed inner ring 200 is not provided with fixed grooves 202, fixed connection grooves are provided on the outer circumferential wall of the fixed inner ring 200, and the fixed magnetic member 203 is fixedly embedded in the fixed connection grooves. The movable magnetic member 102 and the fixed magnetic member 203 can be permanent magnets.

[0099] In some embodiments, the inner peripheral wall of the movable outer ring 100 and the outer peripheral wall of the fixed inner ring 200 are in clearance fit, and the clearance is greater than 0. The movable magnetic element 102 and the fixed magnetic element 203 are like-pole repulsive, preventing contact between the inner peripheral wall of the movable outer ring 100 and the outer peripheral wall of the fixed inner ring 200. When the user's actuation pressure exceeds the magnetic force between the movable magnetic element 102 and the fixed magnetic element 203, the inner peripheral wall of the movable outer ring 100 briefly contacts the outer peripheral wall of the fixed inner ring 200, resulting in short-term wear. This slows down the wear rate of the self-lubricating material, thereby further extending the service life of the decompression ring.

[0100] In some embodiments, the decompression ring further includes a bottom support ring 300 fixedly inserted into the fixed inner ring 200, the outer peripheral wall of the bottom support ring 300 being fitted against the inner peripheral wall of the fixed inner ring 200. The bottom support ring 300 integrates a battery, a control circuit board, a wireless charger, and multiple sensors. These sensors are used to collect the user's physical and physiological data. The physical data includes the flicking pressure and flicking frequency, while the physiological data includes heart rate, blood pressure, and body temperature. Specifically, the multiple sensors include, but are not limited to, Hall effect sensors, inertial sensors, touch sensors, heart rate sensors, blood pressure sensors, temperature sensors, and optical sensors.

[0101] In some embodiments, user physical data (pulling pressure and pulsating frequency) collected by sensors can be processed and used to build or expand a historical user database, thereby providing data support for the thickness iteration design of subsequent products.

[0102] During the application process, the technicians found that the existing rings could only be used by individual users and could not be used to interact with others, indicating that there was room for improvement in the user experience.

[0103] Therefore, in some embodiments, the underlying support ring 300 also integrates a sensory interaction module and a wireless communication module. The current decompression ring is wirelessly connected to the second decompression ring through the wireless communication module. The current decompression ring obtains the touch information of the second decompression ring through the wireless communication module and controls the sensory interaction module to perform corresponding synchronous sensory interaction actions based on the touch information.

[0104] Specifically, the sensory interaction module includes a vibration motor, RGB light strips, etc., and the wireless communication module can use Bluetooth, WiFi, or other wireless communication modules. The current decompression ring is wirelessly connected to a second decompression ring via the wireless communication module. This second decompression ring is, for example, a decompression ring worn and used by a second user. During use, the current user can establish a wireless connection with the second user's second decompression ring through the wireless communication module. When the second user touches their second decompression ring, the current decompression ring performs a corresponding synchronous sensory interaction action based on the received touch information.

[0105] For example, in an embodiment, the current decompression ring integrates a vibration motor in the bottom support ring 300. When the second user touches or clicks the second decompression ring, the current decompression ring controls the vibration motor to vibrate synchronously to perform a sensory interaction action, produce interaction, and improve user experience. In another embodiment, the sensory interaction module is an RGB light strip. When the second decompression ring is dialed, the current decompression ring performs corresponding light strip flashing actions according to the dialing speed.

[0106] In actual application, different users have different sensitivities to sensory feedback. If the sensory feedback does not meet the personal preferences of the user, it may bring additional pressure to the user or reduce the user experience.

[0107] To solve the above technical problems, in some embodiments, the current decompression ring is also used to: obtain personalized data of the user, determine an initial interaction period and an initial interaction frequency of the sensory interaction module based on the personalized data; obtain ring wearing data of the user under the initial interaction period and the initial interaction frequency; optimize the initial interaction period and the initial interaction frequency based on the ring wearing data to generate an optimized period and an optimized frequency; and control the sensory interaction module to perform a corresponding synchronous sensory interaction action based on the optimized period and the optimized frequency.

[0108] Specifically, when the current decompression ring is used, the personalized data of the user is also obtained. For example, the user can be required to input personalized data such as preferred vibration period, preferred vibration frequency, and preferred light strip flashing intensity when wearing the decompression ring, thereby determining the initial interaction period and the initial interaction frequency. However, the above parameters determined initially may not meet the actual preferences of the user. Therefore, during use, the ring wearing data of the user under the initial parameters is further obtained, the preferences of the user under the initial interaction period and the initial interaction frequency are determined according to the ring wearing data, and the above two parameters are further dynamically adjusted and optimized to generate an optimized period and an optimized frequency, and then the sensory interaction module is controlled to perform a corresponding synchronous sensory interaction action.

[0109] In the prior art, in order to enable the movable outer ring 100 to rotate around the fixed inner ring 200, a bearing is often configured in the middle. However, on the one hand, the size of the existing bearing is relatively large, and since the ring is worn on the finger of the user, the increase of the mm-level size will greatly reduce the experience of the user, resulting in a decrease in user experience. On the other hand, small-size high-quality bearings are very expensive, which increases the cost of the product and cannot meet the low-cost demand of the decompression ring use scenario, which is not conducive to improving market competitiveness.

[0110] In order to solve the technical problem, the embodiment of the present application can effectively reduce the overall thickness of the decompression ring by nesting the movable outer ring 100 on the outer peripheral wall of the fixed inner ring 200, and using the movable outer ring 100 provided with self-lubricating material in the above manner, the overall thickness is reduced from the original 5-8mm to about 3mm, greatly improving the user experience.

[0111] In actual application process, the thickness of the self-lubricating material is very important, if the thickness is too large, it will cause the overall size of the decompression ring to be too large, thereby reducing the user experience; if the thickness is too small, due to friction loss, the service life of the decompression ring will be reduced, resulting in user complaints or dissatisfaction.

[0112] Therefore, the embodiment also provides a material thickness determination method of a decompression ring, for determining the thickness of the self-lubricating material filled in the movable groove 101 of the above decompression ring, as shown in the accompanying drawings, Figure 4 The method comprises the following steps:

[0113] S1, determine the friction coefficient: first determine the surface material of the fixed inner ring 200 made of non-self-lubricating material, and then determine the friction coefficient between the self-lubricating material and the surface material.

[0114] S2, data processing: obtain historical user data, and determine the dialing pressure, dialing frequency and expected service life according to the historical user data.

[0115] S3, determine the wear rate: determine the wear rate according to the friction coefficient and the dialing pressure.

[0116] S4, determine the calculation thickness: determine the number of rotations according to the dialing frequency and the expected service life, and then determine the calculation thickness according to the number of rotations and the wear rate. Specifically, after the user selects the surface material of the fixed inner ring 200, the surface properties of the surface material are determined, and based on the material pairing relationship (i.e. the combination of the surface material of the fixed inner ring 200 and the self-lubricating material), the friction coefficient between the two is obtained by experimental measurement or consulting the material database, and the wear of the self-lubricating material by the surface material of the fixed inner ring 200 during use can be determined according to the friction coefficient. The friction coefficient reflects the friction behavior between the interfaces during relative sliding, and is one of the key parameters affecting the wear performance.

[0117] At this time, the historical user data is further obtained, for example, the user use data of the historical sales of the decompression ring or the user use data of similar rings can be obtained to determine the dialing pressure, the dialing frequency and the expected service life. Step S2 specifically comprises the following steps:

[0118] S201. Obtain objective group characteristics and / or first subjective group characteristics of users from historical user data, wherein the objective group characteristics include at least one of the following: occupational category, health status; and the first subjective group characteristics include at least one of the following: degree of tug-of-war preference, anxiety level.

[0119] S202. Using objective group characteristics and / or primary subjective group characteristics as clustering conditions, cluster users to form at least one user group.

[0120] S203. Calculate the toggle pressure, toggle frequency, and expected service life for each user group.

[0121] In some embodiments, in step S202, the clustering conditions further include a second subjective group characteristic, which includes at least one of the following: toggle pressure, toggle frequency, and expected service life.

[0122] In some embodiments, in step S203, the actuation pressure, actuation frequency, and expected service life are calculated by using at least one of the mode, median, and mean.

[0123] Specifically, a large amount of behavioral data and background information on users during actual use of the pressure-relieving ring or similar rings will be collected to form historical user data. From this historical user data, objective group characteristics, first subjective group characteristics, and second subjective group characteristics of the users will be obtained. Objective group characteristics include at least the user's occupation category and health status. Occupation category includes, for example, programmers, doctors, teachers, students, etc.; health status includes, for example, whether the user has been diagnosed with anxiety disorder, sleep disorder, or other physiological or psychological conditions that affect finger dexterity. First subjective group characteristics include at least the user's preference for using the pressure-relieving ring and their anxiety level. The preference for using the ring can be obtained through questionnaires, user interviews, or APP usage records, and is divided into three levels: low, medium, and high. The anxiety level can be classified based on the assessment results of standardized psychological scales such as GAD-7 or HAMA. Second subjective group characteristics include preliminary data on the finger pressure and frequency measured by sensors during actual use, as well as user feedback or system records of the expected lifespan.

[0124] At least one of the acquired objective group characteristics (occupation category, health status), the first subjective group characteristics (dialing preference degree, anxiety level), and the second subjective group characteristics (preliminary dialing stress, dialing frequency, and expected service life) is taken as a clustering condition to construct a multi-dimensional feature vector, and a clustering algorithm (such as K-means clustering, hierarchical clustering, DBSCAN, or Gaussian mixture model) is used to finely group the users. Through clustering analysis, the users are divided into several typical user groups with significant differences, for example: 1) high-intensity occupation use type: the occupation is programmer or doctor, long-time use of keyboard and mouse or surgical instruments, mild wrist fatigue or preventive use demand, preference for medium-high frequency dialing, medium dialing stress; 2) high anxiety high frequency stimulation type: patients diagnosed with anxiety or generalized anxiety disorder, high anxiety level, using the stress ring as an emotional regulation tool, high dialing frequency, long duration, and obvious preference for tactile feedback (high dialing stress); 3) sleep disorder auxiliary type: sleep disorder patients with difficulty falling asleep or frequent waking at night, mainly using before sleep, concentrated use period, medium frequency, and low stress, emphasizing quiet and gentle operation; 4) entertainment preference type: student group, using purpose is inclined to interest and social sharing, dialing preference degree is high but duration is weak, use mode is irregular, and expected service life requirement is medium; 5) minimalist low-frequency use type: healthy adult users, only use temporarily when stressed occasionally, dialing frequency is extremely low, no special preference for stress, and expected service life is long.

[0125] Then, for each user group formed, the representative parameter values are calculated based on the second subjective group characteristic data (i.e. the actually collected or reported dialing stress, dialing frequency, and expected service life data) of the users in the group using statistical analysis methods. Specifically, for each parameter (dialing stress, dialing frequency, and expected service life), at least one of the mode (the value with the highest frequency), the median (the value in the middle after sorting the data), or the mean (arithmetic mean) can be selected for calculation.

[0126] Preferably, the most suitable statistical quantity should be selected according to the distribution characteristics of the data: for example, when there are obvious outliers or skew distribution in the data, the median is preferred to enhance robustness; when the data distribution is relatively symmetric and there are no significant outliers, the mean can be used; when the most common use mode is concerned, the mode can be used. If necessary, weighted average or calculation after removing outliers can be combined to ensure the representativeness and reliability of the parameters.

[0127] Finally, a set of typical dialing stress, dialing frequency, and expected service life parameters accurately reflecting the use behavior of each type of user group is output, providing fine input basis for subsequent wear rate analysis and self-lubricating material design.

[0128] In some embodiments, before clustering the users, the historical user data needs to be pre-processed to obtain the preliminary expected service life, that is, the obtained historical user data includes the actual service life and the user's evaluation of the actual service life, and the preliminary expected service life is obtained through the actual service life and the user's evaluation of the actual service life. For example, the actual service life is 30 days, and the user's evaluation of the actual service life is "hope to use for 10 more days", then the preliminary expected service life is 40 days.

[0129] Based on the determined friction coefficient, in combination with the stress state (dialing pressure) of the decompression ring in actual use, the corresponding wear coefficient K can be derived or experimentally calibrated. The wear coefficient K is closely related to material pairing, surface roughness and lubrication conditions, and is usually positively correlated with the friction coefficient, and an empirical mapping relationship can be established through calibration experiments.

[0130] Subsequently, step S3 is entered, and a classic Archard wear model (Archard's Wear Equation) is used to quantitatively calculate the wear rate. The Archard wear formula is as follows:

[0131]

[0132] Wherein:

[0133] Q: cumulative wear volume (mm 3 );

[0134] W: normal load (N), directly related to the "dialing pressure" applied by the user when dialing the ring, and the "dialing pressure" is obtained through step S2;

[0135] L: total sliding distance (mm), which is directly proportional to the "number of rotation turns", and a certain sliding distance corresponds to each dialing action;

[0136] K: dimensionless wear coefficient, determined by material pairing and friction coefficient;

[0137] H: hardness of self-lubricating material (MPa or N / mm 2 ).

[0138] For engineering application, the above volume wear model is converted into linear wear rate (i.e. thickness loss per rotation turn), defined as "wear thickness per turn". By dividing the wear volume Q by the wear contact area A, the cumulative linear wear amount can be obtained:

[0139]

[0140] Further, assuming that the sliding distance corresponding to one rotation of the dialing ring is l, then the total sliding distance L = n x l, where n is the number of rotation turns. Thus, the average wear thickness per turn is:

[0141]

[0142] The wear rate (c) is the average thickness loss of the self-lubricating material layer in the contact area per rotation of the dial ring, with the unit of mm / revolution.

[0143] Therefore, after knowing the dial pressure W of the user (from step S2), the hardness H of the self-lubricating material, the contact area A, the sliding distance l per rotation of the dial ring, and the wear coefficient K determined by the friction coefficient, the wear rate c of the self-lubricating material per revolution can be calculated.

[0144] At the same time, the rotation number can be determined according to the dial frequency determined in step S2 and the expected service life. Assuming that the dial frequency is a (revolutions / day), the expected service life is b (days), and the rotation number is n (revolutions), then n = a x b. At this time, the calculated thickness can be determined according to the rotation number and the wear rate. The wear rate is c (mm / revolution) determined in step S3, and the design calculated thickness is D (mm), then D = n x c.

[0145] In some embodiments, the method for determining the thickness of the self-lubricating material further comprises the following steps:

[0146] S5, determining the reference thickness: obtaining the expected thickness, comparing the expected thickness and the calculated thickness, and selecting the smaller value or the weighted average value under the preset weight as the reference thickness.

[0147] Since the calculated thickness is calculated according to the expected service life, the calculated thickness obtained may be large, so it is further necessary to comprehensively determine the reference thickness of the self-lubricating material according to the expected thickness and the calculated thickness.

[0148] Firstly, the expected thickness desired by the user or product design is obtained. The expected thickness can be determined based on ergonomic data, overall structure design of the ring, appearance modeling requirements, wearing comfort feedback, and manufacturing process capability, etc. It is usually derived from historical product data, user research or industrial design specifications. For example, in order to ensure light and non-sense wearing, the expected thickness can be set to 0.4-0.6mm.

[0149] Secondly, the calculated thickness calculated according to the wear rate and the rotation number in step S4 is compared with the above-mentioned expected thickness. The calculated thickness is the minimum safe thickness required to ensure that the self-lubricating material is not completely worn out within the expected service life, which has engineering reliability significance.

[0150] Subsequently, the following two methods are selected according to the actual design target to determine the reference thickness: 1) conservative selection method: directly select the smaller value between the calculated thickness and the expected thickness as the reference thickness. 2) weighted average method: in a specific product development stage (such as iterative optimization or balanced design), the calculated thickness and the expected thickness can be weighted and averaged to obtain the reference thickness.

[0151] Optionally, the reference thickness = a * calculated thickness + (1-a) * expected thickness. Wherein, the weight coefficient a is in the range of [0, 1], and is valued according to the design priority. For example, a = 0.7, indicating that more attention is paid to life reliability, focusing on the calculated thickness; a = 0.3, indicating that more emphasis is placed on user experience and appearance design, and the expected thickness is preferred. The weight can be preset according to the product positioning, user group preference or enterprise design standard and fixed in the design process.

[0152] In the embodiment of the application, the annular movable groove 101 is formed in the inner circumferential wall of the movable outer ring 100, the self-lubricating material is filled in the movable groove 101, and the movable outer ring 100 is directly rotationally nested on the outer circumferential wall of the fixed inner ring 200, so as to replace the bearing in the prior art. The technical problems that the size of the bearing in the prior art cannot be further reduced and the lubricating effect of the bearing gradually decreases with the increase of the use time are effectively solved, and the user experience is greatly improved.

[0153] In actual application, there is a big difference between using self-lubricating material and using bearing to realize the rotational connection between the movable outer ring 100 and the fixed inner ring 200. The bearing generally does not have large wear, but the smoothness of rotation is affected. On the contrary, the lubricity of the self-lubricating material is not affected, that is, the smoothness of rotation is not affected, but the self-lubricating material is worn. Therefore, with the increase of the use time, there will be a gap between the self-lubricating material and the fixed inner ring 200, and the gap will increase with the increase of the use time. When the gap increases to a certain extent, the movable outer ring 100 will produce radial swing during the process of rotating around the fixed inner ring 200 by the user, and the expected rotation distance and the actual rotation distance will also deviate, resulting in a decrease in user experience.

[0154] In order to solve the above technical problems, in some embodiments, the method for determining the thickness of the self-lubricating material further comprises the following steps:

[0155] S6, determining the final thickness: determining the final thickness according to the gap between the self-lubricating material and the fixed inner ring 200 and the user experience threshold. Specifically, it includes the following steps:

[0156] S601, determining the nonlinear correspondence between the gap between the self-lubricating material and the fixed inner ring 200 and the user experience.

[0157] S602, acquire a user experience threshold.

[0158] S603, substitute the user experience threshold into the nonlinear correspondence relation to determine the reference gap between the self-lubricating material and the fixed inner ring 200.

[0159] S604, adjust the reference thickness according to the reference gap to obtain a final thickness.

[0160] The adjustment comprises: if the wear gap generated when the reference thickness is worn to a preset lower limit is greater than the reference gap, appropriately reducing the reference thickness; otherwise, maintaining or increasing the reference thickness, thereby obtaining the final thickness.

[0161] Specifically, after determining the reference thickness of the self-lubricating material, a nonlinear correspondence relation between the gap between the self-lubricating material and the fixed inner ring 200 and the user experience is further determined, for example, the nonlinear correspondence relation is acquired and determined by the technician according to experimental data in advance. Then acquire the user experience threshold, which can be a fixed threshold set by the technician according to the experience feedback of the general user, or a personalized threshold set by the current user according to his own perception sensitivity. Then substitute the acquired user experience threshold into the nonlinear correspondence relation to determine the reference gap, and then adjust the reference thickness according to the reference gap to obtain the final thickness.

[0162] For example, after substituting the personalized threshold set by a certain user into the nonlinear correspondence relation to determine the reference gap, it is found that when the self-lubricating material with the reference thickness is worn to a preset lower limit (the remaining thickness of the self-lubricating material reaches a preset lower limit value), the wear gap between the self-lubricating material and the fixed inner ring 200 is greater than the reference gap. Therefore, the thickness of the self-lubricating material is reduced on the basis of the reference thickness to obtain the final thickness; similarly, when the self-lubricating material with the reference thickness is worn to the preset lower limit, the wear gap generated is less than the reference gap, so the thickness of the self-lubricating material is increased on the basis of the reference thickness to obtain the final thickness; when the self-lubricating material with the reference thickness is worn to the preset lower limit, the wear gap generated is equal to the reference gap, so the reference thickness is maintained as the final thickness.

[0163] In the embodiment of the application, the thickness of the self-lubricating material is set through the user-acceptable wear gap, which can effectively improve the user experience, avoid the negative impact of excessive wear of the self-lubricating material on the user experience, and be beneficial to improving the user experience.

[0164] The present application is directed to the fine thickness design of thin-walled structure, which can solve the fundamental contradiction between miniaturization and durability. The decompression ring in the prior art usually adopts a metal bearing structure, which has a large overall size and redundant material thickness, and the service life requirement can be met without accurate calculation. The present application aims to achieve extreme miniaturization and structural simplification, cancels the traditional bearing structure, and adopts a self-lubricating material to realize the rotating function by direct sliding cooperation. Under this background, the self-lubricating material must be designed to be very thin (for example, the thickness is only 0.4-0.6 mm) to ensure the wearing comfort and aesthetics of the overall ring.

[0165] However, the self-lubricating material that is too thin is easily worn out under high-frequency dialing, resulting in structural failure. Therefore, the initial thickness of the self-lubricating material must be accurately calculated and optimally designed, neither too thick (affecting the wearing feeling and appearance) nor too thin (resulting in insufficient service life). The three-level thickness determination method of "calculated thickness - reference thickness - final thickness" proposed by the present application is designed for material life prediction and structural reliability guarantee under such ultra-thin and high-wear conditions, filling the gap in the prior art that lacks systematic thickness design for thin-walled self-lubricating structures.

[0166] In addition, the present application precisely controls the thickness of the self-lubricating material to ensure the stability and consistency of the magnetic jerk feeling. In the present application, the decompression ring is embedded with a movable magnetic part 102 on the inner circumferential wall of the movable outer ring 100 and a fixed magnetic part 203 on the outer circumferential wall of the fixed inner ring 200, so that they periodically experience the state switching of "alignment attraction" and "misalignment separation" during relative rotation, thereby generating regular magnetic force changes to form a perceptible "jerk feeling" or "damping rhythm", which is the core mechanism to improve the decompression effect.

[0167] The "jerk feeling" pursued by the present application is not only a mechanical feedback, but also a psychological intervention means at the level of embodied cognition. Research shows that rhythmic and predictable tactile feedback can effectively activate the brain's reward system and attention regulation grid, helping users establish a sense of control and order, thereby relieving anxiety and improving concentration. Specifically:

[0168] 1) Rhythm: The periodic resistance change caused by magnetic alignment forms a touch rhythm similar to "click" sound or "pulse", which can guide users to enter a meditation or focused state, similar to the "flow" effect of a fingertip gyroscope.

[0169] 2) Predictability: Stable jerk points allow users to obtain consistent feedback in each dialing, enhancing the sense of control and reducing anxiety caused by uncertainty.

[0170] 3) Multi-sensory coordination: combining the slight magnetic attraction sound and finger touch, forming multi-modal feedback, further improving the sense of immersion and decompression effect.

[0171] Therefore, maintaining the stability of the stagnation feeling is not only a mechanical performance requirement, but also a core guarantee for realizing the psychological regulation function.

[0172] However, the magnetic interaction mechanism of the present application is highly sensitive to the structural gap and geometric precision, and the wear of the self-lubricating material directly affects this precision, which is specifically manifested as:

[0173] (1) Magnetic part collision risk: The self-lubricating material is filled in the movable groove 101 opened in the inner circumferential wall of the movable outer ring 100 and distributed around the movable magnetic part 102. During the rotation of the movable outer ring 100 relative to the fixed inner ring 200, the self-lubricating material starts to wear from the inner circumferential wall of the movable outer ring 100. Although the movable magnetic part 102 will also wear synchronously, the materials are different and the wear rates are different. If the self-lubricating material is worn too much, the movable magnetic part 102 is likely to protrude relative to the self-lubricating material. During the rotation of the movable outer ring 100, the protruding movable magnetic part 102 may collide with the fixed magnetic part 203 on the outer circumferential wall of the fixed inner ring 200, producing abnormal noise, jamming or even damaging the magnet, disrupting the smooth magnetic force change curve, and seriously weakening the comfort and controllability of the stagnation feeling.

[0174] (2) Rotation wobble leading to magnetic force misalignment: The self-lubricating material serves as a gap compensation layer and a guide layer between the movable outer ring 100 and the fixed inner ring 200, and its uniform wear can maintain stable sliding fit. Once the self-lubricating material is unevenly worn or insufficient in thickness, the movable outer ring 100 will produce radial wobble or eccentric swing during rotation, causing the relative position between the movable magnetic part 102 and the fixed magnetic part 203 to deviate from the designed trajectory, resulting in misalignment of the magnetic pole pairs, weakening of the attractive force, or violent pushing, which makes the "stagnation point" perceived by the user blurred, misplaced or disappeared, seriously affecting the rhythm and satisfaction of the decompression experience.

[0175] Therefore, it is necessary to ensure that the remaining thickness of the self-lubricating material is sufficient to maintain the stable rotation of the movable outer ring and the accurate alignment of the magnetic parts throughout the entire expected service life through precise thickness design. The present application predicts the total wear amount through a wear rate model and corrects the thickness in reverse in combination with user experience thresholds, which is exactly to ensure the functional integrity of the magnetic interaction system at the end of the life of the self-lubricating material, and to ensure that the "stagnation feeling" is clear, stable and predictable from beginning to end.

[0176] It should be noted that if a fixed groove 202 is formed in the bottom of the mounting groove 201 along the circumference of the fixed inner ring 200, and the self-lubricating material is filled in the fixed groove 202, the thickness of the self-lubricating material filled in the fixed groove 202 is determined by the above method.

[0177] The embodiment also provides a material thickness determination system of the decompression ring, used for determining the thickness of the self-lubricating material filled in the movable groove 101 or the fixed groove 202 of the decompression ring, as shown in the accompanying drawings Figure 5 The embodiment also provides a material thickness determination system of the decompression ring, used for determining the thickness of the self-lubricating material filled in the movable groove 101 or the fixed groove 202 of the decompression ring, as shown in the accompanying drawings

[0184] Embodiment two:

[0185] The embodiment provides a material thickness determination method of the decompression ring, used for determining the thickness of the self-lubricating material of the decompression ring, which is different from the embodiment one in that:

[0186] To further improve the scientificity and flexibility of the user group division, the embodiment introduces a weight distribution mechanism of clustering factors in the clustering process, dynamically adjusts the contribution degrees of various clustering conditions in the clustering process according to the influence degrees of different characteristics on the user behavior, and thus obtains a user group structure more in line with actual needs. The specific implementation manner is as follows:

[0187] 1. Weight setting manner:

[0188] The clustering factors include objective group characteristics (such as occupation category, health status), first subjective group characteristics (such as anxiety level, dialing preference degree) and second subjective group characteristics (such as dialing pressure, dialing frequency, expected service life). The weights of various clustering factors are determined in the following manner:

[0189] 1.1 Pre-set fixed weights: Based on historical user data analysis or expert experience, pre-set the weight values of each feature. For example, in the design of products targeting the working population, the professional category and anxiety level have a greater impact on usage behavior, and can be given higher weights: the professional category weight is set to 0.3, the anxiety level weight is set to 0.3; the health status has a relatively small impact, and the weight is set to 0.1; the remaining features are evenly distributed among the remaining weights.

[0190] 1.2 Dynamic adjustable weights: Provide a user configuration interface or a background management system to allow product designers to manually adjust the weights of each feature according to market positioning, target audience, or promotion stage, and achieve flexible user cluster strategies.

[0191] 1.3 Data-driven weights: Based on historical user data, through correlation analysis (such as Pearson correlation coefficient, mutual information) or machine learning models (such as random forest feature importance ranking), automatically calculate the correlation strength between each feature and key usage parameters (such as dial stress, dial frequency), and generate a weight distribution scheme accordingly. For example, if data analysis shows that "anxiety level" is highly positively correlated with "dial frequency", then "anxiety level" is given a higher weight in clustering.

[0192] 2. Weighted clustering process:

[0193] Before executing the clustering algorithm (such as K-Means, hierarchical clustering or DBSCAN), the original feature vector is weighted. Let the feature vector of user i be:

[0194]

[0195] The corresponding weight vector is:

[0196]

[0197] The weighted feature vector is:

[0198]

[0199] The clustering algorithm calculates the similarity or distance between users based on the weighted feature vector, thus completing the clustering. Through weight adjustment, the dominant role of certain key features in the clustering process can be controlled, avoiding interference from secondary features in the clustering results.

[0200] 3. Weight normalization and constraints:

[0201] To ensure clustering stability, all weights must satisfy the normalization condition:

[0202]

[0203] At the same time, the upper and lower limits of the weight can be set, such as , to prevent a certain feature weight from being too high, resulting in excessive bias in the clustering result.

[0204] 4. Application example:

[0205] For example, when developing a decompression ring for "high-pressure job groups", the system can be set as follows: anxiety level (weight 0.35), occupation category (weight 0.3), frequency of pressing (weight 0.25), and other features (total weight 0.1). The clustering result shows that this group has a typical behavior pattern of high pressing frequency and medium-high stress level, according to which the "group typical pressing stress" and "expected service life" are calculated, and then a thicker self-lubricating material scheme is determined to ensure durability. When targeting "teenage student groups", the weights of "pressing preference degree" and "pressing frequency" can be increased, and the weight of "health status" can be reduced, so as to identify "high-frequency light-touch" users and match a thinner and more sensitive material thickness design.
