Description

Method of a vibrator manufacture according to a real master and a product obtained using this method

Technical Field

The invention relates to a method of manufacturing of a vibrator according to a real master, consisting of a non-invasive, contactless, convenient and easy home creation of a penis 3D model using common tools such as a mobile phone, tablet computer or camera, and of subsequent factory manufacturing of a replica in the form of a functional vibrator.

The invention further comprises a product obtained using this manufacturing method.

Background Art

Attempts to produce vibrators replicating the shape and size of a penis date back to the very beginnings of the industrial manufacture of vibrators.

Amongst other solutions we could name the patent US4335067A consisting of a molding kit to facilitate the synthetic cloning of body parts such as fingers, which includes a supply of alginate powder and a mold form having a bottom opening that is sealed when the form is seated on the base. A supply of powder is mixed with water to form a quick-setting, liquid molding compound. This is poured into the mold form, after which the body member is inserted and held therein until the compound sets to form an elastic gel. The gel is then pushed out of the mold form through the bottom opening, and the body part withdrawn to expose the impression cavity. The gel is returned to the mold form, which is again seated, and a liquid casting compound of the same composition as the molding compound is poured into the cavity and permitted to set to create a flesh-like clone of the body part. This clone can be easily removed from the cavity without damaging the impression.

Another solution is associated with the patent US4828116A, describing a kit and a process for making a representative reproduction of a part of the body of a person in a selected orientation. The kit includes a supply of impression material, a mold-defining cavity member, which may be in two parts, and a supply of plaster so that, the impression material, when combined with water, may be first positioned in the cavity of the mold, an impression made, after the selected body part has been removed from the cavity, a mixture of the plaster and water may be placed in the impression made in the material in the cavity allowed to set and then removed as a product representative of the body part being reproduced.

Another available contact solution according to the patent US2005/285301A1 describes a method of facilitating the molding and casting of a man's penis, which may be completed at a mobile location, including the steps of inserting the penis into a molding container which is filled with a solidifying molding material, withdrawing the penis, thereby creating a negative impression of it, placing a two to five inch phallic shaped vibrating device into the negative impression in order to partially fill the area, and filling the remaining negative impression area with a pour able polyurethane or silicone material capable of curing into a flexible form within the molding material and around the vibrating device, thereby revealing a functional, vibrating replica of the original penis. Using a phallic shaped vibrating device to displace the expensive casting material is what makes this process so economical, as the casting material is typically the most expensive component of the molding and casting process.

Another known solution is based on the patent US2016/136850A1, describing a penis casting method using a kit including a cylinder with a first end cap and a second end cap. An opening may be cut through the sidewall of the cylinder. An opening may also be cut through the first end cap. The user may insert their penis through the opening of the first end cap. A liquid molding material may be poured into the opening through the sidewall so that a substantial portion of the cylinder is filled. The liquid molding material hardens over a first period of time forming a solid mold. The penis may be removed from the solid mold. A liquid casting material is poured into the solid mold and hardens over a second period of time forming a casted penis.

As is evident from the above documents describing the state of the art, a method involving 3D scanning of a real master in a convenient and contactless manner under discrete conditions, followed by custom manufacture according to the customer's master carried out at factory and at economically acceptable costs, has not yet been developed for the purposes in question.

Existing technical solutions may require 3D scanning of the master with a professional industrial scanner, which is very inconvenient and uncomfortable for the user (and almost completely precludes the mass expansion of this method as well as its economic use). The aforementioned method is mainly used in the film industry; see for example the patent CA2734143C describing different methods of creating a 3D model of the human body.

In this case, subsequent manufacturing is carried out individually in a non-factory manner at highly uneconomic costs, which once again rules out mass expansion of the method and its economic use.

Alternatively, as described above, another available method consists in the use of a cylinder filled with a plaster-like substance, which the client pours water in, imprints his penis in, allows it to harden and uses the resulting mold form to cast a clone or a copy out of a gel substance, which is allowed to harden in the mold form and be removed after the mold form is broken.

This second method described in the above-mentioned documents is rather inconvenient for the user too, as it requires certain technical skills and patience; the main disadvantage is the low quality, low durability and questionable health safety of the resulting clone. It is probably for these reasons that no technical solution has yet been adopted in the world that would enable the industrial manufacture of clones on a mass scale at economically acceptable costs.

Summary of the Invention

The essence of the invention lies in the design of the individual steps of manufacturing of a vibrator according to a real master and their combination with each other, the advantage of which is custom make, maximum discretion, precision, painlessness, low economic costs and the associated possibility of mass factory manufacture, thus substantially eliminating the disadvantages of the prior art.

In its various embodiments, the invention comprises steps that can be divided into two logical units, of which the first involves creation of a penis 3D model and the second consists in the actual manufacture of the vibrator according to the master.

The first step consists of creating of a 3D model according to the real body part using a common mobile device (cell phone, tablet or camera). Several routine photographs are taken, especially from above and from the side. The snapshots taken are entered into the ordering system, which, after inputting the length of the penis, creates the resulting 3D model using a photogrammetry calculation or a calculation based on a technique devised thereof. (Once the final 3D model is created, the source photographs are automatically deleted so that the user does not have to worry about their disclosure or other misuse.) Artificial intelligence is applied in the final model creation in order to improve the results and reduce the required number and quality of the photographs, most likely making it a worldwide unique technical solution. This step makes the whole procedure painless, non- invasive and user-friendly. Capturing of the master body portion for the final 3D model is performed using devices commonly available in every household.

Alternatively, there are other technical solutions, such as 3D scanning applications for mobile phones or tablets using the internal sensors (for instance LiDAR or TOF sensors) thereof, can be used to obtain the 3D model according to the master body part. However, given the current state of the art, the results achieved using these alternative methods cannot provide the quality of the resulting 3D model as the solution described above. Similarly, the alternative methods require far better technical skills of the user and computing power of the mobile devices used.

The resulting 3D model will come out in the STL format, which is directly applicable to the industrial 3D printing of the future product frame, on which the final layer will be applied, or to the direct printing of the final product, if an option of the material without the final layer is selected.

The size of the supporting frame and therefore also of the future product (clone) can be scaled according to the technological requirements by manual or automatic modification of the STL file, i.e. the basic shape and proportions remain true to the master, but the overall size of the clone will be automatically scaled down adequately to the final silicone layer to be applied later, so that the dimensions of the final product are identical with the master. At the same time, the calculation of the 3D model automatically addresses the frame or clone ribbing according to rhe pre-programmed parameters in order to achieve the desired solidness of the final product. The calculation of the 3D model will also create an internal cavity (pocket) according to the preprogrammed parameters intended for placing of the vibration mechanism.

The adjustment can be automated, where a customized version of the 3D scanning software is programmed to automatically adjust the overall size of the vibrator according to the thickness of the final material or the customer's preferences, while selecting the ideal position of the hole for placement of the vibration mechanism in terms of the vibration transmission and ideal balance of the product.

The next step consists in 3D printing of the future clone's frame or direct 3D printing of the future clone. The decision whether to print the frame, which will be coated with the final layer in the next step, or whether to print the final product directly, depends on both the chosen material of the product and the current state of the art.

Vibrators are currently mostly made of ABS plastic coated with silicone layer. ABS plastic provides the necessary strength, silicone is absolutely safe for health, has no pores and is therefore hygienically safe and can be easily dyed. At the moment, no manufacturers make vibrators out of biocompatible 3D printing resins such as FormLabs BioMed AMBER. Besides that, various other materials such as metals or plastics are used for manufacturing.

One of the innovations recently used on a global scale is 3D printing using silicone filament (e.g. FormLabs Silicone 40A Resin) . 3D printed products have mechanical and chemical properties very similar to those of cast silicone products. If the future state of the art allows direct 3D printing with silicone at economically acceptable costs, it will probably be more convenient to print the final product from silicone directly without the need for the product frame.

The supporting frame is a hollow body with ribs and with an opening for the insertion of a vibration mechanism, whereby the ribs both stabilize the entire skeleton and transmit vibrations produced by the inserted mechanism. The optimum material for the support skeleton is ABS plastic, but other suitable materials can be used in the 3D printing technique too, e.g., flexible filament giving the final product mechanical properties similar to the real master. 3D printing of the support frame and ribbing is conveniently done in one step.

The next step in the manufacture of a copy of the master consists in the insertion of a vibration mechanism - comprising in particular a control unit with an inductive or contact charged battery and vibration motor (s) - into the opening of the support frame and in its subsequent mechanical fixing. It is desirable to fix the vibration mechanism in the prepared cavity so that it is in firm contact with the ribs of the frame in order to effectively transmit vibrations from the vibration mechanism to the surface of the vibrator, while at the same time eliminating unwanted sounds when used. The inductive charged battery is conveniently placed as close as possible to the surface of the vibrator so that it can be charged with the least possible loss.

Next to that, the supporting frame is coated with a final layer of a non-toxic substance, typically medical-grade silicone or its derivatives, a mixture of substances used in industrial practice to produce the outer surface of vibrators, or gold or other metal suitable for the purpose. The coating of the entire surface of the vibrator with the final layer must allow inductive recharging of the vibrator, while meeting the requirements on its waterproof properties and health safety. The optimum thickness of the final coating is determined according to the material used and the expected degree of hardness, whereby:

- in case of medical-grade silicone the ideal layer thickness conveniently ranges between 0.6 and 3 mm;

- in case of metal the ideal layer thickness conveniently ranges between 0.1 - 0.5 mm.

The advantage of creating replicas by means of the support layer 3D printing is a significant saving in material and therefore reduced cost of the vibrator manufacturing.

In the alternative material version of the product, where the entire clone will only be 3D printed and no final layer will be applied (the "AMBER" option), a special biocompatible BioMed Amber filament manufactured by FormLabs will be used in the 3D printing.

The invention also relates to products obtained using this manufacturing method, comprising a 3D printed support frame based on an individual master obtained from a customer's mobile device, wherein a layer of a non-toxic material, in particular medical- grade silicone or metal or alloys thereof, is applied to the outer surface of the support frame and a vibration mechanism is mounted inside the support frame and/or products directly 3D printed based on an individual 3D master obtained from a customer's mobile device. Convenient parameters of the product and the parts thereof are listed above in the description.
