, Description:TECHNICAL FIELD

The present disclosure generally relates to a field of automobile engineering. Particularly, but not exclusively the present disclosure relates to a clay model of a vehicle. Further embodiments of the present disclosure disclose a method of painting the clay model of the vehicle.

BACKGROUND OF THE DISCLOSURE

In automobile industry, design of automobiles is continuously evolving. An array of vehicles with evolving designs enter into the automobile market every year. In addition to the stiff competition among manufacturers, it is also important to impress customers of any new vehicle models in automotive conferences and shows. Generally, when a new vehicle is being developed, designers create a new design, either in hand sketches or by using computer aided softwares. These drawings or computer models are in the form of two-dimensional sketches or blueprints and, converting these sketched or blueprints into a three-dimensional model is a predominant step. Usually, industrial clay is used to sculpt the three-dimensional model of the sketches or blueprints of the design. The clay models facilitates a designer to evaluate and envisage the design concepts as an original scale three-dimensional model. Also, in order to enhance aesthetic appeal, the clay models, are painted. This provides a visual experience of a finished vehicle. This also, facilitate the designer to evaluate the design as it would appear in after production process.

Conventional techniques of painting the clay model includes, applying the paint coat directly on the surface of the clay model. However, such a technique would deteriorate the properties of the clay, which affects the configuration of the clay model. More particularly, the paint contains thinner, which dissolves the clay, leading to breakdown of the model.

Further, durability of the paint coat on the clay model is affected by the oil or greasy filth accumulated on the outer surface of the clay. The oily or greasy filth have poor absorbability of the paint coat, which may cause blisters and separation of the paint coat film from the clay surface. Further bubbles, folds, sagging, cracks may occur on the surface of the clay model, which affects aesthetic appeal of the clay model to resemble as a finished vehicle. In some techniques to mask the bare clay layer of the clay model, a dinoc film is adapted to cover the outer surface of the clay model. However, such dinoc films have their limitation in view of the type of color and does not allow in applying the paint coat, thus inhibiting the clay model from painting.

The present disclosure is directed to overcome one or more limitations stated above.

The figures depict embodiments of the disclosure for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

DETAILED DESCRIPTION

While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

It is to be noted that a person skilled in the art would be motivated from the present disclosure and would modify the method steps, which may vary from one clay model to other, based on the configuration of the article, which the clay model resembles. However, such modifications should be considered to be within the scope of the disclosure. Accordingly, the drawings show only those specific details that are pertinent to understand the embodiments of the present disclosure, so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having benefit of the description herein.

The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in an arrangement or a system proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.

Embodiments of the present disclosure discloses a method of painting a clay model of a vehicle. Generally, in automotive industry, clay models are sculpted so as to provide a visual representation of the vehicle to be manufactured. In other words, clay model is a three-dimension replica of a finished vehicle which is displayed to the public before the vehicle actually goes into production. However, the outer surface of the clay models tend to have oily or greasy surfaces, which hinder from applying the paint coat, to make the clay model resemble the appearance of the finished vehicle. Further, the paint coat applied on to the clay model may separate or peel off from surface of the model. This may hinder the designer or the viewer from getting an aesthetic appeal of the finished vehicle, which is undesirable.

Accordingly, the present disclosure discloses a method of painting the clay model of the vehicle, such that the clay model resembles the finished vehicle, thus providing a visual effect of the finished vehicle, and yet without affecting the properties of the clay used in the clay model.

In an embodiment, the method of painting the clay model broadly includes cleaning and degreasing an outer surface of the clay model. Once the cleaning and degreasing of the outer surface is completed, a primer coat comprising a mixture of polyvinyl chloride stone chip protector and a binder is applied on to the outer surface of the clay model. The primer coat is then allowed to dry for a first interval of time. The primer coat may form a barrier film on the outer surface of the clay model. Further, upon applying the primer coat, optionally a water-based silver primer coat may be applied on the barrier film. Furthermore, optionally one or more polyurethane coatings may be applied on the water-based silver primer coat. Once, the primer coatings are applied on to the clay model, a paint coat of desired color is applied to the clay model (thus, on the barrier film). The clay model painted by this method resembles appearance of a finished vehicle, and thus provides a visual effect of a finished vehicle.

Henceforth, the present disclosure is explained with the help of figures for a method of painting the clay model of the vehicle. However, such exemplary embodiments should not be construed as limitations of the present disclosure, since the method may be used on clay models resembling other articles, apart from vehicles. A person skilled in the art can envisage various such embodiments without deviating from scope of the present disclosure.

Figure. 1, is an exemplary embodiment of the present disclosure, which illustrates a method of painting a clay model of a vehicle. The sculpted clay model may be painted in order to improve the aesthetic appeal of the clay model, such that the clay model resemble close to the appearance of finished vehicle. In the present disclosure, method of applying the paint coat on the outer surface of the clay model provides aesthetic appeal, without affecting the properties of the clay used in the clay model. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein. The method of painting the clay model of the vehicle is an exemplary embodiment, and the same may be extended to clay models of other articles.

At block 101, an outer surface of the clay model may be cleaned and degreased to remove dirt, dust, stains and the like. In an embodiment, the clay model may be cleaned and degreased using but not limiting a lint free cloth or any other absorbent material. In an embodiment, upon cleaning and degreasing the clay model, a primer coat is applied to the outer surface of the clay model [as seen on block 102] The primer coat may be a mixture of polyvinyl chloride stone chip protector and a binder. In an embodiment, the binder may be but not limiting to a paint binder. After, applying the primer coat, the primer coat may be allowed to dry for a first interval of time. In an embodiment, the first interval of time ranges from about 3.5 hours to 4.5 hours. Upon drying, the primer coat may form a barrier film on the outer surface of the clay model i.e. the primer coat may form a rubberized coat on the outer surface of the clay model. In an embodiment, the barrier film or rubberized coat facilitates in maintain the properties of the clay and allow painting of the clay model.

At block 103, the method includes a step of optionally applying a water-based silver primer coat on the barrier film. The water-based silver primer coat may be allowed to dry for a second interval of time. In an embodiment, the second interval of time may range from about 0.5 hour to 1 hour. Further, the method includes a step of optionally applying one or more polyurethane coatings on the water-based silver primer coat (as seen in block 104). As an example, each polyurethane coating may be applied in a time interval of about 5 minutes to 7 minutes. Further, the one or more polyurethane coatings may be allowed to dry for a third interval of time. In an embodiment, the third interval of time may range from around 3.5 hours to 4.5 hours.

At block 105, the method may include a step of inspecting the clay model, upon applying the primer coat i.e. the mixture of the polyvinyl chloride stone chip protector and a binder on the surface of the clay model, followed by the application of water-based silver primer coat on the barrier film, and one or more layers of polyurethane coating on the water-based silver primer coat. In an embodiment, inspection of the clay model may include examining the flaws (i.e. imperfections, holes) on the surface of the clay model. The detected imperfections and the holes are rectified by filling putty or polyester filler and sanding using sandpapers of required grain size.

Once, the clay model is inspected, at block 106, a paint coat is applied onto the clay model. In other words, the paint coat is applied on to the barrier film, which acts as a protective film between the outer surface of the clay model and the paint coat. Thus, the barrier film may facilitate in maintaining the properties of the clay and, provides an adhesive force for applying paint coat, which improves durability of the paint coat applied. This leads to the clay model to resemble the appearance of the finished vehicle.

In an embodiment, the paint coat applied to the clay model may be, but not limiting to water-borne paint of desired color.

In an embodiment, the method steps performed at blocks 103 and 104 may be repeated after the inspecting the surface of the clay model (block 104), in order to obtain clear or shiny finish upon application of the paint coat.

In an embodiment, the clay model painted by the method of the present disclosure may include a barrier film i.e. rubberized coat, which includes a mixture of a mixture of polyvinyl chloride stone chip protector and a binder, upon which a paint coat may be applied.

In an embodiment, the method may include applying secondary colours for head lamps, tail lamp, wheel arcs and like defined in the clay model.

In an embodiment, sprayers may be used to apply primer coats and paint coats on to the outer surface of the clay model.

Equivalents:

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
