[Technical Field]

[0010] It is preferable to use the configuration of [1], [8] or

[11] above. In this case, a three-dimensional model of the artificial nail to be actually attached to the surface of the natural nail is designed in a virtual space based on the three-dimensional shape information of the natural nail, and three-dimensional model information of the artificial nail is generated. This allows for the accurate production of an artificial nail that matches the three-dimensional shape of the natural nail. Also, an installation space is prepared in advance between the surface of the natural nail and the back surface of the artificial nail when the artificial nail is attached to the natural nail, for placing an intermediate material such as an adhesive or filler. This preparation allows the artificial nail to be stably attached to the subject's natural nail, and the artificial nail is firmly fixed to the natural nail via the intermediate material, thereby improving its fixation and durability. It is recommended to use the configuration described above in [2]. In this case, the installation space is formed in a dome shape, bulging outward in the thickness direction of the artificial nail, allowing the artificial nail to be attached more stably and further improving its fixation and durability. It is recommended to use the configuration described above in [3]. In this case, when the artificial nail is attached to the subject's natural nail, its fixation (adhesion) is improved and the intrusion of external liquids (such as water), tiny particles, or dust is suppressed, thereby increasing the durability of the artificial nail and keeping it hygienic and clean. It is recommended to use the configuration described above in [4]. In this case, since the thickness is set to be approximately uniform overall, the artificial nail can be attached more stably and its fixation and durability can be improved. In particular, when the intermediate body is an adhesive, deviation in the nail length direction or nail width direction during adhesion can be prevented, thereby improving both fixation and durability. It is recommended to use the configuration described above in [5]. In this case, the protrusions sink into or catch on the surface of the intermediate body, which creates an anchoring effect at the bonding surface, firmly bonding the intermediate body and the artificial nail together, further improving the fixation of the artificial nail to the natural nail. It is recommended to use the configuration described above in [6]. In this case, when multiple artificial nails are made for one user, the display of the identifier allows the user to select and attach the appropriate artificial nail from the multiple artificial nails made without making a mistake (mixing up) with the natural nail (fingers) to which they are to be attached. It is recommended to use the configuration described in [7] or

[15] above. In this case, the artificial nail is handmade by, for example, a service provider (a nail salon staff member) based on a model (three-dimensional model) of the subject's finger and natural nail. Since this model has the aforementioned thickness, i.e., is designed to have a predetermined thickness from the surface of the natural nail, the artificial nail produced by the service provider using this model as a base (mold) will have an installation space prepared for placing an interposer between the surface of the natural nail and the underside of the artificial nail when the artificial nail is attached to the natural nail. This preparation allows the artificial nail to be attached stably to the subject's natural nail, and since the artificial nail is fixed to the natural nail via the interposer, it is possible to improve its fixation, durability, hygiene, and cleanliness. It is recommended to use the configuration described above in [9]. In this case, the fixation and durability of the artificial nail to the natural nail can be further improved. It is recommended to use the configuration described above in

[10] . In this case, the fixation and durability of the artificial nail to the natural nail can be further improved. It is preferable to use the configuration described in

[12] or

[13] above. In this case, an annular linear protrusion protruding in the nail thickness direction is disposed on the back surface of the artificial nail, and when the artificial nail is attached to the natural nail, an interposer is placed in the space defined by the linear protrusion. This increases the strength against external forces in the nail width direction and nail length direction, thereby further improving the fixation and durability of the artificial nail. Furthermore, when the artificial nail is attached to the subject's natural nail, the tip of the linear protrusion engages with the surface of the natural nail, thereby suppressing rattling due to external forces and improving attachment stability. Furthermore, the presence of the annular linear protrusion prevents the intrusion of external liquids (e.g., water), fine particles, dust, etc., thereby maintaining hygiene and cleanliness. It is recommended to use the configuration described in

[14] above. In this case, this model (three-dimensional model) is formed with an annular step between the periphery of its thick portion and the periphery of the portion corresponding to the natural nail. Thus, when a service provider uses this three-dimensional model as a base (mold) to create, for example, a handmade artificial nail, the artificial nail material is molded (shape-transferred) at this step, resulting in the formation of an annular linear protrusion on the back surface of the artificial nail. When the artificial nail thus formed is attached to the subject's natural nail, the tip of the linear protrusion engages with the surface of the natural nail, thereby suppressing wobbling due to external forces and improving attachment stability. Furthermore, the presence of the annular linear protrusion prevents the intrusion of external liquids (e.g., water), fine particles, dust, etc., thereby maintaining hygiene and cleanliness. [Effects of the Invention]

[0015] However, more detailed explanations than necessary may be omitted, for example, detailed explanations of well-known matters or redundant explanations of substantially identical configurations may be omitted, in order to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art.

[0016] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims. Each of the accompanying drawings should be referenced according to the orientation of the reference numerals.

[0017] Also, unless otherwise indicated, all numbers expressing parameters, reaction conditions, concentrations of ingredients, and so forth used in this specification and the appended claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and appended claims are approximations that may vary depending, at least in part, on particular analytical techniques.

[0018] <Terminology> The terms "comprising" or "characterized by," which are synonymous with "comprising" and "containing," are to be construed in an inclusive or open-ended sense and do not exclude additional, unrecited elements or method steps. "Comprising" is a term of art used in claim language that means that the named claim element is required, but that other claim elements may be added to further form structure within the scope of the claim.

[0019] Also, as used herein, the phrase "consisting of" excludes any element, step, or ingredient not specified in the claim. When the phrase "consisting of (or variations thereof)" appears in a section of the body of a claim rather than immediately following the preamble, it limits only the elements set forth in that section and does not exclude other elements from the claim as a whole. As used herein, the phrase "consisting essentially of" limits the scope of a claim to those elements or method steps specified in addition to those that do not materially affect the main and novel feature(s) of the claimed subject matter.

[0020] With respect to the terms "comprising," "consisting of," and "consisting essentially of," when one of these three terms is used herein, the presently disclosed and claimed subject matter may also include the use of either of the other two terms.

Furthermore, the functions of one configuration may be realized by two or more physical configurations, or the functions of two or more configurations may be realized by, for example, one physical configuration (for example, one independent device).

[0023] First Embodiment A first embodiment of an artificial nail making method, an artificial nail attaching method, and an artificial nail making system 1 (hereinafter also referred to as "system") according to the present invention will be described with reference to FIGS. In this specification and drawings, elements having substantially the same functions may be denoted by the same reference numerals to avoid redundant explanation.

[0024] [System Configuration] The configuration of the system 1 will be described with reference to FIG. FIG. 1 is a schematic diagram illustrating an example of the configuration of an artificial nail production system 1 according to this embodiment.

[0025] As shown in FIG. 1, the system 1 of this embodiment includes a communication network NW, an information processing device 10, and a 3D printer device 20 (an example of a "real model production unit").

[0026] The communication network NW is connected to the information processing device 10 and the 3D printer 20, and is configured to enable the mutual exchange of various information or signals. The communication network NW also includes at least wired or wireless lines, and is configured to include an Internet line as part or all of these. This allows the communication network NW to enable mutual communication between the information processing device 10 and the 3D printer 20, for example. In other words, the information processing device 10 is configured to be able to access the 3D printer 20 via the communication network NW.

[0027] In addition, the communication network NW may be configured to include a local area network (LAN), a wide area network (WAN), a mobile telephone network (MTN), and other types of networks that are interconnected and used to facilitate communication between the information processing device 10 and the 3D printer device 20, as appropriate.

[0028] The information processing device 10 receives input of information on the three-dimensional shape of the natural nail NN of the subject CS via a camera 11 (see FIG. 3 ), as described below, and generates three-dimensional model information of an artificial nail AN (also commonly referred to as a "fake nail") based on the three-dimensional shape information. The information processing device 10 then transmits the three-dimensional model information to a 3D printer device 20 via a communication network NW. The information processing device 10 is exemplified by, but is not limited to, a notebook computer or a smartphone. For example, the information processing device 10 can also be employed in various other devices, such as a general-purpose personal computer, a mobile phone, a tablet, a laptop computer, a netbook, a personal digital assistant (PDA), a game device, a media player, or an e-book. The information processing device 10 may be any type of information terminal device as long as it can be connected to the communication network NW.

[0029] The 3D printer device 20 creates a model of the artificial nail AN in the real world based on the three-dimensional information transmitted from the information processing device 10. Specifically, the 3D printer device 20 forms an object by stacking molten resin material in layers.

[0030] The configuration of the communication network NW shown in FIG. 1 is an example of this embodiment, and the information processing device 10 and the 3D printer 20 may be directly connected via a wired or wireless connection. For example, the information processing device 10 and the 3D printer 20 may be connected via a connection method such as USB (Universal Serial Bus), IEEE 1394, Bluetooth, or IrDA (Infrared Data Association). The 3D printer 20 may also be configured to include a cloud system. In this case, the functions of the control unit 21 (see below) of the 3D printer 20 are provided by a cloud-based service. Such modifications are naturally included within the technical scope of the embodiments of the present disclosure.

[0031] [Hardware configuration of information processing device] A hardware configuration capable of realizing the functions of the information processing device 10 according to this embodiment will be described with reference to FIGS. FIG. 2 is a block diagram illustrating an example of a hardware configuration capable of realizing the functions of the information processing device 10 shown in FIG. FIG. 3 is a perspective view illustrating an example of how a three-dimensional shape is measured by the camera 11 shown in FIG.

[0032] As will be described later, the functions of the information processing device 10 of this embodiment can be realized using hardware elements exemplified in Fig. 2. Furthermore, the functions of the information processing device 10 are realized by controlling the hardware exemplified in Fig. 2 using a computer program.

[0035] The camera 11 of the information processing device 10 has a light projecting unit (not shown), which emits light toward the finger FG of the subject CS and receives the reflected light with the solid-state imaging element described above, thereby measuring the three-dimensional surface shape of the finger FG including the natural nail NN. The camera 11 of the information processing device 10 then transmits the measurement results as information on the surface shape to the main body of the information processing device 10. The software portion of the camera 11 of the information processing device 10 is installed inside the information processing device 10 as its function, but specifically, the hardware portion of the camera 11 of the information processing device 10 is an external camera that can be installed outside and is connected to an external interface 16 of the information processing device 10, which will be described later.

[0036] In this embodiment, the camera 11 is used as a means for measuring the three-dimensional shape, but this is not limiting. Various technical means can be used as long as they are capable of measuring the three-dimensional surface shape of the natural nail NN of the subject CS. For example, 3D scanning (optical) methods, photogrammetry, stylus probe measurement methods, laser triangulation methods, etc. can be appropriately used. Alternatively, a method of directly molding using a silicon material may be used.

The processor 12 of the information processing device 10 executes programs that realize various functions described below as its central processing unit. As a result, the processor 12 of the information processing device 10 operates functionally as a control unit 101 of the entire computer (see below).

[0038] The memory 13 of the information processing device 10 not only stores and holds programs but also serves as a working memory for the processor 12 of the information processing device 10, and is configured to include various storage devices such as ROM (Read Only Memory) and RAM (Random Access Memory). ROM is an example of a non-volatile semiconductor memory (storage device) that can retain programs and data even when the power is turned off. ROM stores programs and data such as BIOS, OS settings, and network settings that are executed when the computer starts up. RAM is an example of a volatile semiconductor memory (storage device) that temporarily holds programs and data.

[0039] The display interface 14 of the information processing device 10 is an interface circuit for connecting a display device such as an LCD (Liquid Crystal Display) or an ELD (Electro-Luminescence Display). In this embodiment, various three-dimensional models are displayed on the display device in the virtual space through the display interface 14 of the information processing device 10, as will be described later. The communication interface 15 of the information processing device 10 is an interface circuit for connecting to a communication network NW.

[0040] The external interface 16 of the information processing device 10 is an interface circuit for connecting an external device installed outside the information processing device 10. The external interface 16 of the information processing device 10 is, for example, a USB port. To the external interface 16 of the information processing device 10, for example, operation input devices such as a keyboard, a mouse, or a touch panel, or output devices such as a printer, are connected. In addition, to the external interface 16 of the information processing device 10, a recording medium (not shown) that is a non-transitory computer-readable storage medium is connected. Examples of the storage medium include a magnetic recording medium, an optical disk, a magneto-optical disk, and a semiconductor memory.

[0041] The processor 12 of the information processing device 10 reads a computer program stored on a recording medium, stores it in the memory 13 , and controls the operation of the information processing device 10 in accordance with the computer program read from the memory 13 .

[0042] The computer program that controls the operation of the information processing device 10 may be stored in advance in the memory 13 of the information processing device 10, or may be downloaded via the communication interface 15 of the information processing device 10. In this embodiment, the computer program may be, for example, 3D CAD software for designing a 3D model in a virtual space, and the software is installed in the information processing device 10.

[0043] [Hardware configuration of 3D printer device] A hardware configuration capable of realizing the functions of the 3D printer device 20 of this embodiment will be described with reference to FIG. FIG. 4 is a block diagram illustrating an example of a hardware configuration capable of realizing the functions of the 3D printer device 20 shown in FIG.

[0044] As shown in FIG. 4, the 3D printer device 20 includes a control unit 21 and a 3D printer processing unit 30 (an example of a "machining tool").

[0045] The control unit 21 of the 3D printer 20 and the 3D printer processing unit 30 of the 3D printer 20 may be configured separately, or these two units may be configured as an integrated unit. The control unit 21 and the 3D printer processing unit 30 of the 3D printer 20 may be connected via a wired and / or wireless network. In this embodiment, a 3D printer modeling method is used as the machining tool, but this is not limited to this. The method may be a cutting method or a CAM (Computer-Aided Manufacturing) method, and various machining tools can be selected as long as they are capable of forming a predetermined shape. 3D printer modeling methods include FDM (Fused Deposition Modeling), laser sintering, and inkjet printing, and are selected adaptively depending on the embodiment. In the FDM method, a thermoplastic filament is heated and layered to form an object. In the stereolithography method, UV-curable resin is cured with ultraviolet light, allowing for high-resolution modeling. These include technologies such as LCD (Liquid Crystal Display), DLP (Digital Light Processing), and SLA (Stereolithography). Laser sintering uses a laser to sinter powdered materials to create objects, while inkjet printing sprays UV-curable resin and hardens it with ultraviolet light to create shapes.

[0046] The control unit 21 of the 3D printer 20 is configured with electronic devices such as a minicomputer as a hardware configuration. That is, the control unit 21 of the 3D printer 20 is configured similarly to the information processing device 10, and includes a processor 22, a memory 23, a communication interface 25, and an external interface 26.

[0047] In the 3D printer device 20, the processor 22, memory 23, communication interface 25, and external interface 26 are each configured to have the same functions as the processor 12, memory 13, communication interface 15, and external interface 16 of the information processing device 10, as described above. The control unit 21 of the 3D printer device 20 and the 3D printer processing unit 30 of the 3D printer device 20 are connected via the external interface 26.

[0048] The control unit 21 of the 3D printer 20 receives three-dimensional model information of the artificial nail AN from the information processing device 10 through the communication interface 25. The control unit 21 of the 3D printer 20 temporarily stores and holds the received three-dimensional model information in its memory 23. The control unit 21 of the 3D printer 20 then controls the operation of the 3D printer processing unit 30 with its processor 22, and causes a model of the artificial nail AN to be produced (processed) in the real world based on the three-dimensional model information stored and held in the memory 23. The material of the artificial nail AN, the printing method, etc. can be selected arbitrarily according to the embodiment.

[0049] The 3D printer processing unit 30 includes, as hardware components, a housing (not shown), a printer head (not shown), and a filament supply unit (not shown).

[0050] The housing of the 3D printer processing unit 30 is formed in the shape of a metal box, providing a structural foundation and ensuring high structural rigidity and stability. The printer head of the 3D printer processing unit 30 has a spray nozzle at its tip, which deposits the filament supplied in a molten state from the filament supply unit in a specific pattern. Furthermore, the printer head of the 3D printer processing unit 30 has multiple linear axes that intersect with each other, and the spray nozzle moves precisely along, for example, the X-axis (a first direction following the horizontal direction), the Y-axis (a second direction following the horizontal direction and perpendicular to the first direction), and the Z-axis (a vertical direction). The filament supply unit of the 3D printer processing unit 30 melts the filament, which is a synthetic resin material, and supplies it approximately uniformly to the spray nozzle of the printer head of the 3D printer processing unit 30.

[0051] Examples of synthetic resin materials include thermoplastic resins such as acrylic, polyamide, polycarbonate, polyester, etc. In addition to these synthetic resin materials, ceramic materials such as zirconia and lithium disilicate, and metal materials such as titanium and cobalt can also be used, and mixtures of the aforementioned synthetic resin materials and metal materials can also be used.

[0052] As described above, the control unit 21 of the 3D printer 20 is configured to include software and hardware, and plays a central role in coordinating the operation of the 3D printer 20. The control unit 21 of the 3D printer 20 analyzes the data (three-dimensional model information) transmitted from the information processing device 10, and controls the operation of the printer head and other mechanisms of the 3D printer processing unit 30 based on the analysis results. That is, in this embodiment, the system 1 is configured to include the 3D printer 20, and produces an artificial nail AN in the real world using the 3D printer processing unit 30 of the 3D printer 20 based on the three-dimensional model information transmitted from the information processing device 10.

[0053] The 3D printer device 20 also has multiple adjustment functions for improving accuracy, such as controlling the thickness of layers, printing speed, and temperature, etc. These adjustment functions enable the system 1 to handle various materials for the artificial nail AN and to create complex shapes.

[0054] The 3D printer processing unit 30 of the 3D printer 20 further includes multiple detection units (e.g., sensors, not shown). The multiple detection units of the 3D printer 20 detect the operating status of the device in real time. The control unit 21 of the 3D printer 20 adaptively adjusts or stops the operation of the 3D printer processing unit 30 based on the detection results.

[0055] [Functional configuration of information processing device] The functional configuration of the information processing device 10 will be described with reference to FIG. FIG. 5 is a block diagram illustrating an example of the functions of the information processing device 10 shown in FIG.

[0056] As described above, the information processing device 10 is configured to have the processor 12 as a hardware configuration, and the processor 12 of the information processing device 10 realizes various functions by reading and executing various programs from the memory 13. As a result, various processes related to the generation of three-dimensional model information of the artificial nail AN, including shape information acquisition and model information generation, are executed.

[0057] As shown in FIG. 5, in this embodiment, the information processing device 10 includes a control unit 101, a storage unit 104, and a communication unit 105 as functions realized by the operation of hardware such as the processor 12.

[0058] The memory unit 104 of the information processing device 10 is a function realized by operating including the storage device of the information processing device 10 (in cooperation with the processor 12) as described above, and stores and holds information regarding three-dimensional shape information relating to the surface shape of the natural nail NN and three-dimensional model information of the artificial nail AN. The communication unit 105 of the information processing device 10 is a function realized by operating including the communication interface 15 of the information processing device 10 as described above, and communicates with the 3D printer device 20. The control unit 101 of the information processing device 10 is a function realized by the processor 12 of the information processing device 10 reading programs stored and held in the memory 13 of the information processing device 10, and performs processes related to the acquisition and generation of three-dimensional information.

[0059] The control unit 101 of the information processing device 10 includes a shape information acquisition unit 102 and a model information generation unit 103.

[0060] The shape information acquisition unit 102 of the information processing device 10 acquires three-dimensional shape information relating to the surface shape of the natural nail NN. The information is acquired, for example, by measuring the three-dimensional surface shape of the natural nail NN of the subject CS with the above-mentioned camera 11 and transmitting the information, or by inputting a record of three-dimensional shape information acquired by measurement in the past or acquired from the outside into the device main body via the above-mentioned storage medium.

[0061] The model information generation unit 103 of the information processing device 10 designs, in a virtual space, a three-dimensional model of the artificial nail AN to be actually attached to the surface of the natural nail NN, based on the three-dimensional shape information, and generates three-dimensional model information of the artificial nail AN related to the model. Specifically, the three-dimensional shape information is presented on a display device of the information processing device 10 through its display interface 14. Then, while appropriately referring to or confirming the presented content, the user of the information processing device 10 uses an operation input device connected to the external interface 16 of the information processing device 10 to design the artificial nail AN in a virtual space provided by, for example, three-dimensional CAD software. As a result of the design, three-dimensional model information related to the artificial nail AN is generated.

[0062] In this embodiment, the user of the system 1 uses an operation input device to perform the design, but this is not limiting. The model information generation unit 103 of the information processing device 10 may be configured to be able to autonomously or automatically design the installation space IS.

[0063] At this time, the model information generating unit 103 of the information processing device 10 of this embodiment designs the model of the artificial nail AN that is actually produced (in the real world) by the 3D printer device 20 so that when the artificial nail AN is actually attached to the natural nail NN, an installation space IS for attaching (installing) an interposing body IB (see below) exists (is secured) between the surface of the natural nail NN and the back surface of the artificial nail AN (see Figures 6 and 7).

[0064] Three-dimensional model information of the artificial nail AN designed in this manner is transmitted to the 3D printer device 20 through the communication interface 15 of the information processing device 10. The 3D printer device 20 receives the three-dimensional model information through the communication interface 25, and produces (processes) a model of the artificial nail AN in the real world using the 3D printer processing unit 30 (see below).

[0065] The material of the artificial nail AN is appropriately selected from at least one of thermoplastic resins such as acrylic, polyamide, polycarbonate, and polyester, and / or ceramic materials such as zirconia and lithium disilicate, and metal materials such as titanium and cobalt, or mixtures thereof.

[0066] [Artificial nail structure] The structure of the artificial nail AN according to this embodiment, which is designed by the model information generating unit 103 of the information processing device 10 and is actually produced by the 3D printer device 20, will be described with reference to FIGS. FIG. 6 is a side view illustrating an example of a state in which the artificial nail AN produced by the system 1 shown in FIG. 1 is attached to the natural nail NN. FIG. 7 is a cross-sectional view taken along the line AA shown in FIG. FIG. 8 is a schematic cross-sectional view illustrating an example of the structure of the joint surface between the artificial nail AN and the intermediate piece IB shown in FIG.

[0067] As shown in Figures 6 and 7, the artificial nail AN that is produced (or designed in virtual space) is curved in both its longitudinal direction (meaning the "direction in which the nail grows and extends"; also called the "nail longitudinal direction") and its width direction (the extension direction perpendicular to the longitudinal direction; also called the "nail width direction"). The term "extending direction" used here is interpreted as a term meaning a surface (flat surface, curved surface, etc.) direction, including the concepts of both the "nail longitudinal direction" and the "nail width direction."

[0068] In the artificial nail AN, a virtual shape corresponding to the installation space IS is formed so as to extend in the shape of a three-dimensionally curved plate. The back surface of the virtual shape of the installation space IS is formed to resemble the surface of the natural nail NN. The virtual shape of the installation space IS is formed so that the thickness at the center in the nail width direction is greater than the thickness at its edge portions in the width direction (nail width direction), and the virtual shape bulges upward (toward the front side in the thickness direction) compared to the back surface. Furthermore, the virtual shape of the installation space IS is formed so that the thickness at the center in the extension direction is approximately uniform. The installation space IS is also formed so that, when the artificial nail AN is attached to the natural nail NN of the subject CS, the edge in the nail width direction of the installation space IS on the back surface coincides with the edge in the nail width direction of the natural nail NN. In this case, when the artificial nail AN is attached to the natural nail NN of the subject CS, its fixation (adhesion) is improved and durability can be enhanced by suppressing the intrusion of external liquids (such as water). Alternatively, the central portion of the surface in the extending direction may be formed flat.

[0069] That is, the imaginary shape of the installation space IS is formed asymptotically so that when the artificial nail AN is attached to the natural nail NN, its widthwise edge portion comes close to the natural nail NN via the intermediate body IB, and the thickness becomes uniform toward the center portion. This formation makes it possible to prevent gaps from occurring between the natural nail NN, the artificial nail AN, and the intermediate body IB when the artificial nail AN is fixed to the natural nail NN via the intermediate body IB.

[0070] Immediately before attaching the artificial nail AN to the natural nail NN, an interposing body IB (for example, a sheet-like member or a double-sided tape material, see below) is affixed to the surface of the natural nail NN. At this time, since there is an installation space IS on the back surface of the artificial nail AN as described above, the interposing body IB is appropriately interposed between the natural nail NN and the artificial nail AN in this attached state, and the artificial nail AN is more firmly fixed to the natural nail NN.

[0071] The intermediate body IB is a material interposed between the natural nail NN and the artificial nail AN, and functions as a filler or adhesive that fills the gap between the natural nail NN and the artificial nail AN. It is adaptively selected from materials such as glue, gummies, and double-sided tape, depending on the type of natural nail NN. Glass polyalkenoate cement and polycarboxylate cement (cements used in dentistry) may also be used as the intermediate body IB. In this embodiment, due to their adhesive properties, it is more preferable for the intermediate body IB to contain glass polyalkenoate cement and / or polycarboxylate cement. In this case, the fixation and durability of the artificial nail AN can be improved.

[0072] The material of the intermediate body IB is not limited to the above-mentioned materials, and various materials can be used as long as they function as a filler or adhesive to fill the gap between the natural nail NN and the artificial nail AN. This gap corresponds to the installation space IS mentioned above.

[0073] Also, as shown in FIG. 8, in this embodiment, the model information generating unit 103 of the information processing device 10 is designed to provide countless tiny protrusions PP on the back surface of the artificial nail AN, or after production by the 3D printer device 20, countless tiny protrusions PP, more specifically, countless random uneven shapes (an example of "multiple uneven portions") are formed on the back surface of the artificial nail AN by a separate sandblasting process or the like.

[0074] As a result, the numerous protrusions PP form irregularities on the back surface of the artificial nail AN and the adhesive surface of the insert IB, resulting in increased surface area and adhesion between the artificial nail AN and the insert IB. This provides a so-called anchor effect bond (mechanical adhesion), and when the artificial nail AN is attached to the natural nail NN via the insert IB, the insert IB penetrates and gets caught between the protrusions PP, resulting in a complex bond. This bond allows the natural nail NN and the artificial nail AN to be more firmly bonded, improving fixation and durability.

[0075] [Operation flow using this system] With reference to FIG. 9, the operation flow using the present system 1, that is, the method for producing an artificial nail and the method for attaching an artificial nail, will be described. FIG. 9 is a flow diagram illustrating an example of an operation flow when the system 1 shown in FIG. 1 is used.

[0076] As shown in FIG. 9, the operation flow (method) according to this embodiment includes a shape information acquisition step S11, a model information generation step S12, a real model production step S13, a material attachment step S14 (material attachment step), and an artificial nail attachment step S15.

[0077] The aforementioned shape information acquisition step S11, model information generation step S12, and real model creation step S13 can also be understood as a group of steps constituting the artificial nail production method of the present invention. In addition to the artificial nail production method, the process further including material attachment step S14 and artificial nail attachment step S15 can also be understood as a group of steps constituting the artificial nail attachment method.

[0078] In the shape information acquisition step S11, the camera 11 of the information processing device 10 measures the three-dimensional surface shape of the finger FG including the natural nail NN, with the finger FG of the subject CS as the measurement target. Then, the camera 11 of the information processing device 10 transmits the measurement result as information on the surface shape to the main body of the information processing device 10. The shape information acquisition unit 102 of the information processing device 10 receives the information and thereby acquires three-dimensional shape information related to the surface shape of the natural nail NN.

[0079] Note that this acquisition is not limited to the transmission of the results of measurement by the camera 11 of the information processing device 10, but may also be achieved by inputting past records into the main body of the information processing device 10 via the above-mentioned storage medium. Also, in this embodiment, the shape information acquisition step S11 is executed by the control unit 101 of the information processing device 10, but is not limited to this. As long as this step can be executed, it is not limited to execution by a computer program, and various embodiments can also be adopted, such as execution by a dedicated electronic device.

[0080] In the model information generating step S12, the three-dimensional shape information is presented on the display device through the display interface 14 of the information processing device 10. Then, the user of the information processing device 10, while referring to the presented content, designs in a virtual space using an operation input device or the like connected to the external interface 16 of the information processing device 10. As a result of the design, three-dimensional model information of the artificial nail AN is generated.

[0081] At this time, in the model information generating step S12, the model of the artificial nail AN that is actually produced (in the real world) by the 3D printer device 20 is designed so that when the artificial nail AN is attached to the natural nail NN, an installation space IS for attaching (installing) the interposing body IB exists between the surface of the natural nail NN and the back surface of the artificial nail AN (see FIGS. 6 and 7). Then, the model information generating unit 103 of the information processing device 10 transmits the three-dimensional model of the artificial nail AN obtained as a result of the design to the 3D printer device 20 as three-dimensional model information of the artificial nail AN.

[0082] Similarly, in this embodiment, the model information generating step S12 is executed by the control unit 101 of the information processing device 10 described above, but is not limited to this. As long as this step can be executed, it is not limited to execution by a computer program, and various other embodiments, such as execution by a dedicated electronic device, can also be adopted.

[0083] In the real model creation step S13, the control unit 21 of the 3D printer 20 analyzes the data (three-dimensional model information) sent from the information processing device 10 and controls the operation of the printer head and other mechanisms based on the analysis results. As a result of this control, a model of the artificial nail AN is created in the real world.

[0084] In the material attachment step S14, the user or subject CS attaches (an example of "attaching") an interposer IB to the surface of the natural nail NN before attaching the artificial nail AN created by the 3D printer device 20 to the natural nail NN corresponding to the artificial nail AN. During this attachment, the user or subject CS covers the entire surface of the natural nail NN with the interposer IB and then attaches it. After this attachment, the artificial nail AN is attached to the natural nail NN via the interposer IB and fixed (secured) (i.e., artificial nail attachment step S15).

[0085] [Features and advantages of this embodiment] As described above, the artificial nail production method of this embodiment includes a shape information acquisition step S11 in which the three-dimensional surface shape of the natural nail NN of the subject CS is measured or information on the surface shape is input to acquire three-dimensional shape information related to the surface shape of the natural nail NN, a model information generation step S12 in which a three-dimensional model of the artificial nail AN to be actually attached to the surface of the natural nail NN is designed in a virtual space based on the three-dimensional shape information and three-dimensional model information of the artificial nail AN related to the model, and a real model production step S13 in which a model of the artificial nail AN is produced in the real world using a 3D printer processing unit 30 (an example of a "machining tool") based on the three-dimensional model information. Furthermore, in the model information generation step S12, the model of the artificial nail AN is designed so that an installation space IS exists for installing an interposer IB that will be interposed between the surface of the natural nail NN and the back surface of the artificial nail AN when the artificial nail AN is actually attached to the natural nail NN.

[0086] The artificial nail attaching method of this embodiment also includes a shape information acquiring step S11 in which the three-dimensional surface shape of the natural nail NN of the subject CS is measured or information on the surface shape is input to acquire three-dimensional shape information relating to the surface shape of the natural nail NN, a model information generating step S12 in which a three-dimensional model of the artificial nail AN to be actually attached to the surface of the natural nail NN is designed in a virtual space based on the three-dimensional shape information and three-dimensional model information of the artificial nail AN related to the model, a real model creating step S13 in which the artificial nail AN is created in the real world using a 3D printer processing unit 30 (an example of a "machining tool") based on the three-dimensional model information, and a material attaching step S14 in which an interposer IB is attached to the surface of the natural nail NN before the artificial nail AN is attached to the natural nail NN corresponding to the artificial nail AN. In the model information generating step S12, the model of the artificial nail AN is designed so that an installation space IS exists for installing the interposer IB between the surface of the natural nail NN and the back surface of the artificial nail AN when the artificial nail AN is actually attached to the natural nail NN.

[0087] Furthermore, the artificial nail production system 1 of this embodiment includes a shape information acquisition unit 102 that acquires three-dimensional shape information relating to the surface shape of the natural nail NN by measuring the three-dimensional surface shape of the natural nail NN of the subject CS or by inputting information about the surface shape, a model information generation unit 103 that designs in a virtual space a three-dimensional model of the artificial nail AN to be actually attached to the surface of the natural nail NN based on the three-dimensional shape information and generates three-dimensional model information of the artificial nail AN relating to the model, and a 3D printer device 20 (an example of a "real model production unit") that has a 3D printer processing unit 30 (an example of a "machining tool") and produces the artificial nail AN in the real world based on the three-dimensional model information. Furthermore, the model information generation unit 103 designs the model of the artificial nail AN so that there is an installation space IS for installing an interposer IB that will be interposed between the surface of the natural nail NN and the back surface of the artificial nail AN when the artificial nail AN is actually attached to the natural nail NN.

[0088] For this reason, a three-dimensional model of the artificial nail AN to be actually attached to the surface of the natural nail NN is designed in a virtual space based on the three-dimensional shape information of the natural nail NN, and three-dimensional model information of the artificial nail AN is generated. This makes it possible to accurately produce an artificial nail AN that matches the three-dimensional shape of the natural nail NN. Furthermore, an installation space IS is prepared in advance for placing an interposing member IB, such as an adhesive or filler, between the surface of the natural nail NN and the back surface of the artificial nail AN when the artificial nail AN is attached to the natural nail NN. This preparation ensures stable attachment when the artificial nail AN is attached to the natural nail NN of the subject CS, and the artificial nail AN is firmly fixed to the natural nail NN via the interposing member IB, thereby improving its fixation and durability.

[0089] Furthermore, according to the method for producing an artificial nail of this embodiment, the imaginary shape corresponding to the installation space IS is formed to extend like a plate. The back surface of the imaginary shape of the installation space IS is formed to resemble the surface of the natural nail NN. The imaginary shape of the installation space IS is formed so that the thickness at the center in the nail's longitudinal direction is greater than the thickness at its edge in the nail's width direction.

[0090] Therefore, the installation space IS is formed in a dome shape, bulging outward in the thickness direction of the artificial nail AN, allowing the artificial nail AN to be attached more stably and further improving its fixation and durability.

[0091] Furthermore, according to the artificial nail manufacturing method of this embodiment, the imaginary shape of the installation space IS is formed so that the thickness at the center in the extension direction (both the nail length direction and the nail width direction) is uniform.

[0092] Therefore, the thickness of the central portion in the extending direction is set to be approximately uniform, so that the artificial nail AN can be attached more stably, and the fixation and durability thereof can be further improved.

[0093] Furthermore, according to the method for producing an artificial nail of this embodiment, a plurality of protrusions PP are provided on the back surface of the artificial nail AN.

[0094] Therefore, the protrusions PP are embedded in or caught on the surface of the intermediate body IB, which provides an anchoring effect at the bonding surface, firmly bonding the intermediate body IB and the artificial nail AN together. As a result, the fixation of the artificial nail AN to the natural nail NN can be further improved.

[0095] Furthermore, according to the artificial nail attaching method of this embodiment, in the material attaching step S14, the intermediate body IB is attached to cover the entire surface of the natural nail NN.

[0096] This further improves the fixation and durability of the artificial nail AN to the natural nail NN.

[0097] Furthermore, according to the artificial nail attaching method of this embodiment, the interposer IB contains glass polyalkenoate cement and / or polycarboxylate cement.

[0098] This further improves the fixation and durability of the artificial nail AN to the natural nail NN.

[0099] [First Modification of the Present Embodiment] The structure of the shape of the installation space IS of a first modified example according to this embodiment will be described with reference to FIG. FIG. 10 is a cross-sectional view illustrating an example of the shape of the installation space IS according to a first modified example of this embodiment.

[0100] As shown in Fig. 10, in the artificial nail AN of this modified example, the imaginary shape corresponding to the installation space IS is formed as a three-dimensionally curved plate-like extension, as in the above-described embodiment. The back surface of the imaginary shape of the installation space IS is formed to resemble the surface of the natural nail NN. However, in this modified example, each edge portion of the imaginary shape of the installation space IS in the nail width direction is formed to taper asymptotically toward the tip in the nail width direction. Furthermore, the tip portion is formed to be curved or spherical, and is rounded.

[0101] In this case, when the artificial nail AN is attached to the natural nail NN of the subject CS, its fixation (adhesion) is improved and the durability of the artificial nail AN can be increased by suppressing the intrusion of external liquids (such as water), tiny particles, or dust.

[0102] [Second Modification of the Present Embodiment] The structure of the artificial nail AN according to the second modified example of this embodiment will be described with reference to FIGS. FIG. 11 is a side view illustrating an example of a state in which the artificial nail AN is attached to the natural nail NN according to this modification. FIG. 12 is a cross-sectional view taken along the line BB shown in FIG.

[0103] As shown in FIGS. 11 and 12, similar to the above-described embodiment, the artificial nail AN is curved in both its lengthwise direction and its widthwise direction, and an installation space IS is defined on the rear side thereof.

[0104] In this modification, the installation space IS is set to have a uniform (substantially uniform) thickness along its extension direction. In other words, the virtual shape of the installation space IS is formed so that its thickness is generally uniform in both the nail longitudinal direction and the nail width direction. In this case, the same configuration and effects as those of the present embodiment are achieved, but since the thickness is set to be approximately uniform overall, the artificial nail AN can be attached more stably and its fixation and durability can be improved. In particular, when the interposing body IB is an adhesive or the like, deviation in the nail length direction or nail width direction during adhesion can be prevented, thereby improving the fixation, durability, hygiene, and cleanliness of the artificial nail AN.

[0105] [Second Modification of the Present Embodiment] The structure of the artificial nail AN according to the third modified example of this embodiment will be described with reference to FIGS. FIG. 13 is a side view illustrating an example of a state in which the artificial nail AN is attached to the natural nail NN according to this modification. FIG. 14 is a cross-sectional view taken along line CC shown in FIG. FIG. 15 is a schematic diagram illustrating an example of how the artificial nail AN is attached to the natural nail NN according to this modification.

[0106] 13 to 15, similar to the above-described embodiment, the artificial nail AN is curved in both its longitudinal direction and its width direction, and an installation space IS is defined on the rear surface side thereof. The artificial nail AN is formed to extend three-dimensionally in a plate shape corresponding to the installation space IS.

[0107] The rear surface of the imaginary shape of the installation space IS is formed to resemble the surface of the natural nail NN. However, in this modification, the length of the imaginary shape of the installation space IS in the nail longitudinal direction is set to be smaller than the length of the natural nail NN in the nail longitudinal direction. Also, the length of the imaginary shape of the installation space IS in the nail width direction is set to be smaller than the length of the natural nail NN in the nail width direction.

[0108] Furthermore, when viewed in the nail thickness direction, the outline of the virtual shape of the installation space IS is positioned inside the outline of the natural nail NN. Accordingly, an annular virtual gap is formed between the outline of the virtual shape of the installation space IS and the outline of the natural nail NN. An annular linear protrusion is designed on the back surface of the model of the artificial nail AN to correspond to the virtual gap. As a result, the annular linear protrusion portion RB is actually disposed and molded on the manufactured artificial nail AN.

[0109] In other words, in this modified example, a ring-shaped linear protrusion RB is designed in virtual space on the back surface of a model of the artificial nail AN. At this time, the linear protrusion RB is designed so that when the artificial nail AN is produced in the real world and attached to the natural nail NN, its tip engages with the periphery of the natural nail NN, and the space surrounded by the linear protrusion RB becomes the installation space IS.

[0110] In this case, an annular linear protrusion RB is disposed on the back surface of the artificial nail AN, protruding in the nail thickness direction. When the artificial nail AN is attached to the natural nail NN, an interposing member IB is placed within the space defined by the linear protrusion RB (i.e., the installation space IS). This increases the strength against external forces in the nail width direction and nail length direction, thereby further improving the fixation and durability of the artificial nail AN. Furthermore, when the artificial nail AN is attached to the natural nail NN of the subject CS, the tip of the linear protrusion RB engages with the surface of the natural nail NN, thereby suppressing wobbling due to external forces and improving attachment stability. Furthermore, the presence of the annular linear protrusion RB seals the edges of the natural nail AN. This sealing prevents external liquids (e.g., water), fine particles, or dust from entering the interior, thereby maintaining hygiene and cleanliness.

[0111] [Fourth Modification of the Present Embodiment] The structure of the artificial nail AN according to the fourth modified example of this embodiment will be described with reference to FIG. FIG. 16 is a schematic diagram illustrating an example of the shape of the back surface of the artificial nail AN according to this modification.

[0112] 16, for example, in the model information generating step S12, the artificial nail AN is designed so that the identifier ID is engraved (expressed as an example of "disposition") in a concave-convex shape on the back surface thereof. Based on this design, the identifier ID is disposed (expressed as raised) on the back surface of the produced artificial nail AN.

[0113] The identifier ID of this modified example is engraved with the letters "R1" to indicate which finger FG of the subject CS the artificial nail AN is to be attached to the natural nail NN of.

[0114] The character "R1" shown in Fig. 16 is an example and means the natural nail NN of the first finger FG on the right hand. Furthermore, in this modified example, as another aspect of the protrusion PP, four circles with a concave-convex shape are provided and arranged at approximately equal intervals. The identifier ID mentioned above is arranged at the center of the four protrusions PP that represent these circles.

[0115] In this modification, the identifier ID is designed by the model information generating unit 103 of the information processing device 10, but is not limited to this. The identifier ID may be provided on the manufactured artificial nail AN by, for example, cutting work. Furthermore, the term "marking" in this modification includes concepts such as protrusion and / or depression, and its technical meaning is broadly interpreted as the formation of a distinguishable three-dimensional shape.

[0116] In this case, when multiple artificial nails AN are produced for one user by displaying the identifier ID, the appropriate one can be selected from the multiple artificial nails AN produced and attached without making a mistake (mixing up) with the natural nail NN (finger FG) to be attached. In addition, the same configuration and effects as those of this embodiment are achieved.

[0117] Second Embodiment A second embodiment of an artificial nail making method, an artificial nail attaching method, and an artificial nail making system 1 (hereinafter also referred to as "system 1") according to the present invention will be described with reference to FIGS. In addition, the same or equivalent parts as those in the first embodiment described above will be denoted by the same or equivalent reference numerals in the text of this specification or in the drawings, and the description thereof will be omitted or simplified.

[0118] [Operation flow of this embodiment] The operation flow according to this embodiment, that is, the method for producing and attaching an artificial nail, will be described with reference to FIGS. FIG. 17 is a flow diagram illustrating an example of an operation flow when the system 1 according to this embodiment is used. FIG. 18 is a schematic diagram illustrating an example of how an artificial nail AN is produced using a finger model MG according to this embodiment.

[0119] As shown in FIG. 17, the operation flow (method) according to this embodiment includes a shape information acquisition step S21, a model information generation step S22, a real model creation step S23, and an artificial nail creation step S26.

[0120] In the shape information acquisition step S21 of this embodiment, the three-dimensional surface shape of not only the natural nail NN but also the finger FG from which the natural nail NN grows is measured, or information on the surface shape is input, thereby acquiring three-dimensional shape information relating to the surface shapes of the finger FG and the natural nail NN. In this embodiment, similarly to the first embodiment, the shape information acquisition step S21 is executed by the control unit 101 of the information processing device 10, but the present invention is not limited to this.

[0121] In the model information generating step S22 of this embodiment, a three-dimensional model (three-dimensional model) corresponding to the finger FG and natural nail NN is designed in a virtual space based on the three-dimensional shape information, and three-dimensional model information is generated for the model to produce an artificial nail AN that will actually be attached to the surface of the natural nail NN. At this time, in this embodiment, the model MG of the finger FG and natural nail NN (hereinafter also referred to as the "finger model") is designed in advance to have a predetermined thickness from the surface of the natural nail NN. The shape of this thickness may be formed similarly to the installation space IS of the first embodiment described above. That is, in the model information generating step S22 of this embodiment, the finger model MG corresponding to the finger FG and natural nail NN is designed to have a predetermined thickness from the surface of the natural nail NN and to have a plate-like thick portion that extends in a plate shape. In this embodiment, as in the first embodiment, the model information generating step S22 is executed by the control unit 101 of the information processing device 10, but the present invention is not limited to this.

[0122] In the real model creation step S23 of this embodiment, the control unit 21 of the 3D printer device 20 analyzes the data (three-dimensional model information) transmitted from the information processing device 10 and controls the operation of the printer head and other mechanisms based on the analysis results. As a result of this control, a finger model MG corresponding to the finger FG and natural nail NN described above is created in the real world (see FIG. 18). The finger model MG of this embodiment is formed in accordance with the design in the model information generation step S22 described above, with a thickness that intentionally causes the portion corresponding to the natural nail NN to bulge upward compared to the outer shapes of the finger FG and natural nail NN of the actual subject CS. The thickness may be formed in a dome shape, as in the first embodiment, or may be formed to be approximately uniform.

[0123] In the artificial nail production step S26 of this embodiment, the user or subject CS produces the artificial nail AN based on the finger model MG, which is molded to have a thickness, i.e., a thick plate portion, compared to the actual nail, as described above. The finger model MG is used as a mold for the finger FG and natural nail NN of the subject CS, and the user, for example, produces the artificial nail AN by hand by imitating the mold.

[0124] Furthermore, in this embodiment, the artificial nail AN produced according to the mold is molded in the same manner as in the first embodiment described above so that when the artificial nail AN is attached to the natural nail NN, an installation space IS for installing the intermediate body IB is present between the surface of the natural nail NN and the back surface of the artificial nail AN.

[0125] [Features and advantages of this embodiment] The artificial nail production method of this embodiment includes a shape information acquisition step S21 in which the three-dimensional surface shapes of the finger FG of the subject CS and the natural nail NN growing on the finger FG are measured or information on the surface shape is input to acquire three-dimensional shape information related to the surface shapes of the finger FG and the natural nail NN; a model information generation step S22 in which a three-dimensional shape model (three-dimensional model) corresponding to the finger FG and the natural nail NN is designed in a virtual space based on the three-dimensional shape information and three-dimensional model information related to the three-dimensional model is generated for producing an artificial nail AN to be actually attached to the surface of the natural nail NN; a real model production step S23 in which a model of the finger FG and the natural nail NN (i.e., a finger model MG) is produced in the real world using a 3D printer processing unit 30 (an example of a "machining tool") based on the three-dimensional model information; and an artificial nail production step S26 in which an artificial nail AN is produced based on the model (finger model MG) corresponding to the finger FG and natural nail NN actually produced in the real model production step S23. In the model information generating step S22, the model corresponding to the finger FG and natural nail NN is designed to have a plate-like thick portion that has a predetermined thickness from the surface of the natural nail NN and extends in a plate-like shape.

[0126] For this reason, the artificial nail AN is handmade by, for example, a service provider (a nail salon staff member) based on a model (three-dimensional model) of the finger FG and natural nail NN of the subject CS. At this time, this model has the aforementioned thickness, i.e., it is designed to have a predetermined thickness from the surface of the natural nail NN. Therefore, the artificial nail AN produced by the service provider using this model (finger model MG) as a base (mold) will have an installation space IS prepared for placing an interposer IB between the surface of the natural nail NN and the back surface of the artificial nail AN when the artificial nail AN is attached to the natural nail NN. With this preparation, the artificial nail AN can be stably attached when attached to the natural nail NN of the subject CS, and the artificial nail AN is fixed to the natural nail NN via the interposer IB, thereby improving its fixation, durability, hygiene, and cleanliness. Other configurations and operations are the same as those of the first embodiment. In this embodiment, the artificial nail AN is assumed to be handmade by a person, but is not limited to this. For example, the artificial nail AN may be configured to be automatically produced using a predetermined mechanical tool (application of printing technology) on a mold made from a model (three-dimensional model) of the subject CS's finger FG and natural nail NN. A specific example of this is a case in which a semi-molten, flexible resin sheet having a predetermined thickness is automatically placed on the mold using a conveying device. In this example, after the resin sheet is placed, it is irradiated with light such as ultraviolet light using a lighting device to solidify the resin sheet, thereby automatically producing the artificial nail AN.

[0127] [First Modification of the Present Embodiment] An example of how an artificial nail AN is produced using a finger model MG according to a first modified example of the present embodiment will be described with reference to FIG. FIG. 19 is a schematic diagram illustrating an example of how an artificial nail is produced using a finger model MG according to this modification.

[0128] As shown in FIG. 19, the length of the thick plate portion in the nail longitudinal direction of this modified example is set to be smaller than the length of the natural nail NN in the nail longitudinal direction. Furthermore, the length of the thick plate portion in the nail width direction is set to be smaller than the length of the natural nail NN in the nail width direction. The thick plate portion is disposed in the center of the extension direction (both the nail longitudinal direction and the nail width direction) of the portion of the finger model MG (an example of a "three-dimensional model") that corresponds to the natural nail NN. Furthermore, in this modified example, an annular step ST is disposed in this finger model MG between the peripheral edge of the thick plate portion and the peripheral edge of the portion that corresponds to the natural nail NN.

[0129] In this case, the finger model MG (three-dimensional model) is formed with an annular step ST between the periphery of its plate thickness portion and the periphery of the portion corresponding to the natural nail NN. Thus, when a service provider uses the finger model MG (an example of a "three-dimensional model") as a base (mold) to, for example, handcraft an artificial nail AN, the material of the artificial nail AN is molded (shape transferred) at this step ST, resulting in an annular linear protrusion on the back surface of the artificial nail AN (see FIG. 19). When the artificial nail AN thus formed is attached to the natural nail NN of the subject CS, the tip of the linear protrusion engages with the surface of the natural nail NN, thereby suppressing rattle due to external forces and improving attachment stability. Furthermore, the presence of the annular linear protrusion prevents the intrusion of external liquids (e.g., water), fine particles, dust, etc., thereby maintaining hygiene and cleanliness.
