Description

[Technical field]

[0001] The present invention relates to a nail buying and selling system and a management system. [Background technology]

[0002] For example, Patent Document 1 (JP 2021-137515 A) discloses a method for producing completely custom-made nail tips tailored to the shape of an individual's natural nails, and an order-taking system for the same. That is, a mold kit is used to mold the nail shape of a fingertip, which is made by placing mold-making resin such as resin clay, which is harmless to the human body and can be thermoplastically processed with hot water, in a plastic container, and then a model of the nail shape is made by pouring in the model resin, and a model for a nail tip that fits perfectly to the nail shape of a person in a remote location is made. Also, a model of the nail shape is made using the mold kit, and a resin that will be the base of the nail tip is applied on top of it and hardened, and nail treatment is performed on the base, to make a nail tip that fits perfectly to the nail shape. The customer (requester) and the maker (recipient) can place an order for gel nail tips that fit the customer's desired nail shape perfectly by communicating via the website, email, LINE, phone, catalogs, etc., and by sending and receiving the impression kit and nail tips via courier. This means that the customer does not have to go to a nail salon in person, so they can get nails even in remote areas where there is no nail salon nearby. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-137515 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when making a finger mold using clay or the like, the mold changes shape as the user's finger moves, so it is not accurate, and it is questionable whether a finger model that fits the user's nails well can be obtained. Also, for example, if a nail design is copied without permission, the creator of the nail design does not receive the profits that he or she should receive. In other words, there is no proper consideration given to the provision of fair compensation to the parties involved, and it is difficult to say that this is a sufficient nail buying and selling system.

[0005] Therefore, the object of the present invention is to provide a nail buying and selling system and management system that allows a customer (user) to obtain nail tips that fit the user's nails and have a desired design without having to go to a nail salon, and that takes into full consideration the provision of appropriate compensation to related parties such as the creators of the nail designs. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides: a management system including a design management unit that manages a plurality of nail designs as non-fungible tokens by associating each of the plurality of nail designs with a creator, and allows a nail design selected by a user from the plurality of nail designs to be viewed only by a person designated by the user (e.g., a nail artist or a nail salon to which the nail artist belongs), and a settlement unit that pays remuneration based on a predetermined remuneration distribution rule; a 3D scanner that scans a user's fingertip or an impression material on which the user's fingertip has been molded to generate scan data; A 3D printer that models a finger model based on the scan data, when the selected nail design is applied to a nail tip at the designated nail salon using the modeled finger, the settlement unit pays a reward to the creator of the selected nail design and the designated nail installer in accordance with the predetermined reward distribution rules; The present invention provides a nail buying and selling system, characterized by:

[0007] In the nail buying and selling system of the present invention, it is preferable that the design management unit manages the multiple nail designs using a blockchain including a program that defines the specified reward distribution rules.

[0008] In addition, in the nail buying and selling system of the present invention, it is preferable that the management system further includes a display unit that displays all or a part of the plurality of nail designs on a user terminal for selection by the user.

[0009] In the nail buying and selling system of the present invention, it is preferable that the settlement section also pays a fee to an advertiser of a performance-based advertisement selected by the user.

[0010] The present invention also provides a method for producing a method for manufacturing a semiconductor device comprising the steps of: a design management unit that associates each of a plurality of nail designs with a creator and manages them as non-fungible tokens, and allows a nail design selected by a user from the plurality of nail designs to be viewed only by a creator designated by the user; A settlement unit that pays rewards based on predetermined reward distribution rules; A finger data acquisition unit that acquires scan data generated by scanning a user's fingertip or an impression material on which a mold of the user's fingertip has been made; and an output unit that transmits the scan data to a 3D printer that creates a finger model; When the selected nail design is applied to a nail tip using the shaped finger model, a reward is paid to the creator and the installer of the selected nail design in accordance with the predetermined reward distribution rules; The present invention also provides a management system comprising: Effect of the Invention

[0011] According to the present invention, a user can obtain nail tips that fit the user's nails and have a desired design without going to a nail salon, and a nail buying and selling system and management system can be provided that takes into full consideration the provision of appropriate remuneration to relevant parties such as the creators of the nail designs.

[0013] Representative embodiments of the nail buying and selling system and management system according to the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to those shown in the drawings. In addition, since each drawing is intended to conceptually explain the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for ease of understanding. Furthermore, in the following description, the same or equivalent parts are given the same reference numerals, and duplicated descriptions may be omitted.

[0014] 1. Configuration of Nail Trading System 1 The nail buying and selling system 1 is configured by combining elements such as a nail salon 40, a scan point 20, and design solicitation and evaluation (see FIG. 1). The nail buying and selling system 1 can be configured as a computer system including a terminal and a server connected to each other so as to be able to communicate with each other. Here, the nail buying and selling system 1 will be described assuming a case where a user 60 orders nail tips 73 with a desired design via a user terminal 61. However, this system can also handle orders for toenails, and can also be used to order models of one's own fingers.

[0015] Here, the user terminal 61 is a terminal used by a user 60 of the nail tip 73. The user terminal 61 includes a desktop computer, a laptop computer, and a personal digital assistant (including a smartphone, a tablet terminal, and a wearable terminal). The user terminal 61 includes at least one of a browser for viewing a website provided by the management system 10 and an application for accessing the management system 10. The user terminal 61 also includes a display.

[0016] A user 60 can access the management system 10 and a website provided by the management system 10 via a user terminal 61 to register as a member, register a subscription, select a design and a nail artist, and register a payment method.

[0017] Here, the member registration is performed by registering user information such as the user 60's name, address (delivery address for the product), telephone number, email address, payment method (credit card information, etc.), user ID, and password in the management system 10. The user information may include the order history of the user 60. A subscription may be, for example, a regular purchase of the same nail design or a continued purchase of nail designs created by the same manicurist.

[0018] A user 60 visits a scan point 20 (see FIG. 3). Here, it is assumed that the user visits a physical store. The scan point 20 is, for example, a facility such as a store where a 3D scanner 22 is installed, and may be a nail salon 40.

[0019] 1-1. Store terminal 21 and 3D scanner 22 A store terminal 21 is installed at the scan point 20. The store terminal 21 is preferably configured as a desktop computer or a laptop computer, but may be a mobile information terminal (including a smartphone, a tablet terminal, and a wearable terminal). It is preferable that at least one store terminal 21 is installed at each store of the scan point 20.

[0020] The store terminal 21 receives the scan data 71 from the 3D scanner 22. The store terminal 21 may process the scan data 71, such as correcting missing data or noise. The store terminal 21 may transmit the scan data 71 to the management system 10 in association with user information (e.g., a user ID). Alternatively, the store terminal 21 may transmit the scan data 71 and the user information to the modeling location terminal 31.

[0021] A 3D scanner 22 is connected to the store terminal 21. The 3D scanner 22 scans the shape of the fingertip of the user 60 and generates scan data 71. The 3D scanner 22 transmits the generated scan data 71 to the store terminal 21 together with, for example, the date and time of generation. Note that the fingertip of the user 60 to be scanned naturally includes the nail (at least the base of the nail).

[0022] If either the contact type or the non-contact type is possible, the 3D scanner 22 is preferably the non-contact type. That is, the 3D scanner 22 preferably obtains the three-dimensional shape of the fingertip of the user 60 by irradiating the target (the fingertip of the user 60) with light from a light source such as a laser and analyzing the reflection time difference and irradiation angle. The 3D scanner 22 may be an imaging function of a camera or a portable information terminal under the control of the user 60, as long as it has the performance to adequately capture the three-dimensional shape of the fingertip.

[0023] Specifically, what is obtained from the 3D scanner 22 is point cloud data. Such data is appropriately processed, such as deleting unnecessary parts, removing noise (smoothing), filling in missing parts, synthesizing data, and aligning data, and is converted into mesh data such as STL data or polygon data, and furthermore, additional processing is performed as necessary to obtain scan data 71. Such operations may be processed on software included with the 3D scanner 22, or may be processed by other software. An example of the scan data 71 is shown in FIG. 4.

[0024] The scanning accuracy is preferably 20 μm to 50 μm. That is, if the resolution is high and less than 20 μm, the installation costs and the scan data 71 will increase. If the resolution is low and more than 50 μm, the shape of the fingertip of the user 60 cannot be reproduced sufficiently.

[0025] 1-2. Modeling location terminal 31 and 3D printer 32 The modeling location 30 is a location where a finger model 72 is manufactured based on the scan data 71, and includes a factory. The modeling location 30 may be installed within the scan point 20 and the nail salon 40.

[0026] A modeling location terminal 31 is installed in the modeling location 30. The modeling location terminal 31 is preferably configured as a desktop computer or a laptop computer, but may be a mobile information terminal (including a smartphone, a tablet terminal, and a wearable terminal). At least one modeling location terminal 31 is installed in each modeling location 30, and can receive scan data 71 from the store terminal 21 or the management system 10. The modeling location terminal 31 may also serve as both the store terminal 21 and the salon terminal 41.

[0027] A 3D printer 32 is connected to the modeling location terminal 31. The 3D printer 32 models a finger model 72 based on the scan data 71. The 3D printer 32 can use a known modeling method such as a powder sintering additive manufacturing method, an inkjet method, a fused deposition modeling method, or a photolithography method. In this embodiment, a photolithography method can be preferably used, in which a liquid photocurable resin is hardened by applying ultraviolet light and then layered one by one to produce a desired three-dimensional object. Among them, a DLP (Digital Light Processing) method is more preferable, in which a photocurable liquid resin (resin liquid) is irradiated with projector light to harden the resin and form a shape. An example of a shaped finger model 72 is shown in FIG.

[0028] The shaped finger model 72 is sent to the nail salon 40 for the production of the nail tip 73. Alternatively, based on the request of the user 60, it may be sold to the user 60 for self-nail application.

[0029] 1-3.Salon terminal 41 At Nail Salon 40, nail designs are created by creative artists such as manicurists. At the nail salon 40, a nail tip 73 is produced by a manicurist based on the finger model 72 and the selected nail design. An example of the produced nail tip 73 is shown in Fig. 6. The produced nail tip 73 is sent (sold) to the user 60 and attached to the finger F of the user 60. An example of the nail tip 73 attached to the finger F of the user 60 is shown in Fig. 7.

[0030] The manicurist creates a nail design and applies the nail design to the nail tip 73 at the nail salon 40 or at another location. The manicurist may also take pictures of the process of creating the nail design. The nail artist's profile is registered in the management system 10, for example, via a salon terminal 41 described below. The profile includes, for example, the nail artist's name, pen name, career history, representative works, etc., and is associated with information such as ID, address, telephone number, email address, and payment method (bank account, etc.).

[0031] Here, the manicurist whose nail design is adopted by the user 60 is referred to as the "design-adopting manicurist," and the manicurist who creates the nail tip 73 based on the adopted design is referred to as the "production manicurist." The design-adopting manicurist and the production manicurist may be the same person or different people.

[0032] A salon terminal 41 is installed in the nail salon 40. The salon terminal 41 is preferably configured as a desktop computer or a laptop computer, but may be a mobile information terminal (including a smartphone, a tablet terminal, and a wearable terminal). It is preferable that at least one salon terminal 41 is installed in each salon.

[0033] A manicurist can access the management system 10 via the salon terminal 41 and register not only as a member and a subscription, but also register a profile as a manicurist and a nail design (i.e., image data). In addition, the manicurist can register video data of the creation process of the corresponding nail design in the management system 10. Furthermore, the manicurist can receive a request for production of the nail tip 73 from the management system 10 via the salon terminal 41. The nail artist who has adopted the design can receive the design fee from the management system 10 via the salon terminal 41. The manicurist who created the design can receive the production fee from the management system 10 via the salon terminal 41.

[0034] 1-4. Management System 10 The management system 10 is a computer that manages various data such as user information, scan data 71, nail artist information, nail designs, etc. The management system 10 is, for example, a server computer and may be composed of one or more computers. The management system 10 may provide various services by cloud computing.

[0035] 2, the management system 10 may include functional units such as a design management unit 11, a settlement unit 12, a display unit 13, a finger data acquisition unit 14, and an output unit 15. Each functional unit will be described below.

[0036] The design management unit 11 registers the nail design (image data) in association with the manicurist who created it (i.e., the manicurist who adopted the design, or the creator). The nail design is preferably created in a file format such as JPG or PNG, has a resolution of 300 dpi or higher, and a size of 8.9 cm on each side, but is not limited to this.

[0037] Specifically, nail designs and nail artist information (e.g. ID) are managed as non-fungible tokens (NFTs). In other words, nail designs are non-substitutable digital data created based on the blockchain. As such, nail designs are non-substitutable and originals and copies can be clearly distinguished, so they have asset value and can be traded on the marketplace. Furthermore, since records on the blockchain are virtually impossible to tamper with, NFTs are completely managed.

[0038] However, the design management unit 11 permits viewing of the nail designs for a terminal used by a manicurist who applies the design to the nail tip 73 (i.e., the producing manicurist), such as the salon terminal 41. Such viewing permission grants temporary viewing authority to the relevant terminal, and for example, a predetermined authority is granted after the purchase price has been paid and the authority is revoked after the user 60 receives the product.

[0039] In this embodiment, the underlying blockchain is assumed to be a distributed ledger with programmability, such as Ethereum, but is not limited to this. Therefore, a program that "pays a portion of the sales to the nail artist who uses the design for each sale" can be added to the NFT in advance, and this allows the nail artist who uses the design to receive a specified reward each time a sale is made.

[0040] In addition, the design management unit 11 can register a video of the creation process of a registered nail design in association with the nail design. The video may be created in a known file format such as MP4, AVI, MOV, etc., but is not limited to these. The video may or may not be incorporated into the blockchain.

[0041] Next, the settlement unit 12 determines the amount to be paid by the user 60, charges the user 60, and confirms and records the payment by the user 60. The settlement unit 12 also determines remuneration and fees to be paid to related parties including the manicurists (the manicurist who adopts the design and the manicurist who creates the design) and the advertising affiliate 50 described below, and executes and records the payments. Of course, the settlement unit 12 may determine the remuneration to the manicurist, etc. based on the amount obtained by deducting a portion of the amount paid by the user 60 as a handling fee or management fee.

[0042] The display unit 13 displays all or a part of the multiple nail designs on the user terminal 61 for selection by the user 60. In other words, the display unit 13 is a web server that displays the multiple nail designs on the display of the user terminal 61 in response to a request from the user terminal 61 (browser). Alternatively, the display unit 13 may transmit data of the multiple nail designs to the user terminal 61 in response to a request from an application installed in the user terminal 61. The display unit 13 also displays the registered manicurists on the display of the user terminal 61, and allows the user 60 to select a manicurist who will apply the nail design to the nail tip 73 (i.e., a producing manicurist). The producing manicurist may be selected by an individual manicurist or by a nail salon.

[0043] The display unit 13 may transmit image data with a smaller resolution and size than the nail designs registered in the design management unit 11 to the user terminal 61. The display unit 13 may also embed a digital watermark (any information imperceptible to humans, such as the copyright holder, licensee, logo, content ID, whether copying is permitted and the number of times, and billing information) or a message such as "no copying" in the nail designs registered in the design management unit 11, and transmit the nail designs with the digital watermark to the user terminal 61. This makes it possible to prevent unauthorized use of the nail designs.

[0044] The display unit 13 notifies the design management unit 11 of the nail design and the creating manicurist selected by the user. This enables the design management unit 11 to permit the selected nail design to be viewed on a terminal used by the creating manicurist (e.g., salon terminal 41).

[0045] The finger data acquiring unit 14 acquires the scan data 71 from the store terminal 21, and registers the data in association with the user 60. The management system 10 may further register the scan data 71 in association with the date and time of its generation. In other words, the finger data acquiring unit 14 can be configured as a database including the scan data 71, the user 60, and other data.

[0046] The output unit 15 outputs the scan data 71 to the 3D printer 32 that models the finger model 72. Alternatively, the output unit 15 may transmit the scan data 71 to the modeling location terminal 31 connected to the 3D printer 32.

[0047] Furthermore, the management system 10 can manage and record the delivery of the model from the modeling location 30 to the user 60 or the manicurist who produced the model, and the delivery of the product (nail tip 73) from the manicurist who produced the model to the user 60.

[0048] Additionally, the nail buying and selling system 1 may include an affiliate terminal (not shown) used by an advertising affiliate 50. The advertising affiliate 50 is a person who posts performance-based advertisements on his / her own website or on the website of another company. For example, when a user 60 purchases a model or a product via an affiliate advertisement, a commission is paid to the person who posted the affiliate advertisement.

[0049] 1-5. Computers Constituting the Shop Terminal 21, the Modeling Location Terminal 31, the Salon Terminal 41, and the Management System 10 The computers constituting the store terminal 21, the modeling location terminal 31, the salon terminal 41 and the management system 10 each include a calculation device, a storage device, and a communication interface (I / F), and may further include an input device and an output device (none of which are shown). The computer may be composed of one computer or multiple computers.

[0050] The arithmetic unit realizes the above-mentioned various functions by reading various programs and data into the storage device and executing them. The arithmetic unit may be composed of a semiconductor integrated circuit such as a central processing unit (CPU), a graphics processing unit (GPU), or a microprocessor.

[0051] The storage device includes a random access memory (RAM) and a read-only memory (ROM) for storing various data and programs. The storage device may include, for example, a hard disk drive, a solid-state drive, or a flash memory.

[0052] The input device is used to input various data, and is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, etc. The input device may include a 3D scanner 22. The output device outputs various data, and is, for example, a display, a printer, a speaker, etc. The output device may include a 3D printer 32.

[0053] A communication interface is an interface for connecting to wired and wireless communication networks, such as an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, etc.

[0054] 2. Processing procedure of nail buying and selling system 1 The processing procedure of the nail buying and selling system 1 will be described mainly with reference to FIG.

[0055] A user 60 completes membership registration via a user terminal 61 on a website provided by the nail buying and selling system 1 (including an application installed on the user terminal 61). In addition, a manicurist who designs nails can register as a member and register his / her profile and nail design via, for example, salon terminal 41. The registered nail designs (images and videos of the nail design creation process) are strictly managed as NFTs.

[0056] A user 60 visits a scan point 20 (including a store such as a nail salon 40). At the scan point 20, a finger impression of the user 60 is captured by a 3D scanner 22, and scan data 71 is generated (see FIG. 4). The scan data 71 is transmitted from the 3D scanner 22 directly or via the store terminal 21 to the management system 10 and stored therein. The scan data 71 is transmitted from the management system 10 to the modeling location terminal 31.

[0057] At the modeling location 30, a finger model 72 is modeled by a 3D printer 32 based on the scan data 71 (see FIG. 5). The modeled finger model 72 is sent to a manicurist (such as a nail salon 40) to produce a nail tip 73. The modeled finger model 72 may be sent to a user 60 for self-nail care.

[0058] Additionally, the user 60 selects a nail design and a manicurist and completes payment on the website provided by the nail buying and selling system 1 via the user terminal 61 (browser). Alternatively, the user 60 may select a design and a manicurist and complete payment via an application installed on the user terminal 61. At this time, if the user 60 purchases a product via the affiliate advertisement, a specified commission is paid to the publisher of the affiliate advertisement, and a specified remuneration is paid to the manicurist who created the selected design.

[0059] The management system 10 grants viewing authority for the selected nail design to the manicurist or the terminal used by the manicurist. Viewing authority may be granted temporarily until the completion of the production of the nail tip 73. Of course, unauthorized persons are not permitted to view the nail design, so unauthorized duplication of the nail design is not possible, and the asset value of the nail design is maintained.

[0060] The manicurist who makes the nail browses the selected design from the terminal that he or she uses (for example, salon terminal 41). Then, the manicurist who makes the nail applies a design to the nail tip 73 using the delivered finger model 72 and the selected design.

[0061] Specifically, the manicurist sets up a finger model 72. The manicurist also displays or prints the nail design on a screen. Next, the manicurist selects a nail tip 73 that matches the nail design and finger model 72, places it on the finger model 72, and draws on the nail tip 73 according to the nail design (see FIG. 6). At this time, if a slightly thick tape is applied to the tip of the nail of the finger model 72 before the application, a recess or depression is formed on the inner surface of the completed nail tip 73. Due to the presence of such a recess, when the user 60 attaches the nail tip 73 to the nail, a gap is formed between the nail and the nail tip 73. By using this gap, the user 60 can easily peel the nail tip 73 off the nail by using the principle of leverage. Alternatively, the scan data 71 may be generated so that a convex portion is formed at the nail tip of the finger model 72 .

[0062] The nail tip 73 with the design is sent to the user 60 and is worn on the finger of the user 60 (see FIG. 7). A predetermined remuneration is also paid to the manicurist who created the nail tip.

[0063] 3. Effects of this embodiment According to this embodiment, various nail designs are displayed on the user terminal 61, so the user 60 can select a preferred design. The nail designs are managed as NFTs and cannot be copied without permission, so they are almost unique and highly valuable designs for the user. In addition, since the finger model is shaped based on the scan data 71 obtained by accurately scanning the fingertip of the user 60, the finger model faithfully reproduces the fingertip of the user 60. The nail tip designed using such a finger model is fully adapted to the shape of the fingertip of the user 60. Therefore, a user can obtain a nail tip that fits the user's nail and has a desired design, without having to go to a nail salon.

[0064] In addition, remuneration or commission will be paid in accordance with the rules to the creator of the nail design selected by the user 60, the installer who applied the nail design to the nail tip, and the distributor of the affiliate advertisement that the user 60 clicked (selected) when purchasing the product. Therefore, it is possible to provide a nail buying and selling system that takes into full consideration the provision of fair compensation to those involved, such as the creators of nail designs.

[0065] Although one embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to these embodiments, and there are other improvements and modifications within the scope of the spirit and teachings of the claims. It will be easily understood by those skilled in the art that all such improvements and modifications are included in the technical scope of the present invention.

[0066] For example, in the above embodiment, the case where the fingertip of the user 60 is scanned has been described, but an impression material on which the fingertip of the user has been molded in advance may be scanned. As such an impression material, a conventionally known material may be used, for example, an impression material made of silicone resin.

[0067] If a kit that uses impression material to take impressions of fingertips is made and sent to the user by mail, the user can take the impression of their fingertip themselves. The impression can then be scanned and reversed and printed on a 3D printer to create a model. If users can take impressions of their fingertips themselves in this way, it will be possible to do everything by mail without the user having to go to a scanning point.

[0068] In another embodiment, scan data of a user's fingertip or an impression of the user's fingertip may be used to create a base for a specialized nail tip (a precursor, so to speak) using software, which may then be 3D printed out of a transparent material.

[0069] If there is a precursor made of a transparent material, the labor of lengthening, which requires the skill of the nail artist, can be eliminated, and nail tips can be made only by mechanical work such as coloring, design, and adjustment of the shape, etc. Therefore, even manicurists who are not good at lengthening can sell specialized nail tips with length according to the user's request, and the nail sales system according to the present invention can be used more effectively.
