Description:FIELD OF THE INVENTION
The present invention relates to a stationary, convex shape artwork-casing display module integrated into a ceiling fan. Specifically, the present invention pertains to a system and method for structurally forming a convex artwork-casing module that adapts to the fundamental structure of a ceiling fan's rotor-housing, yielding a sleek, compact, and minimalist appearance.

BACKGROUND OF THE INVENTION
The end users for this invention are residential and commercial building owners, referred to as "house owners" in this context. This invention pertains to the ceiling fan product market. For decades, end users have relied on ceiling fans as a household necessity. Once purchased, a ceiling fan is typically used for 30 years or more, until it no longer functions. Consequently, it can be considered a one-time purchase for 95-98% of consumers, with the remaining 2-5% potentially replacing it during renovations. As a one-time purchase, end users are stuck with a single design and look for an extended period, with no option to change it annually to suit their evolving tastes. The aesthetic appeal of a fan is a critical factor in the purchasing decision for end users. Unlike walls, which can be repainted or refinished with various materials, textures, or wallpapers, ceiling fans offer limited possibilities for aesthetic modifications.
Considering a near-future scenario where consumers can choose between a regular fan and one with a stationary artwork-casing, allowing them to change the printed graphic layer like a photo frame; they will likely opt for the latter. This preference stems from the freedom to change the fan's look and access to limitless design options, all at a similar price point as regular fans.
As observed, most consumers prefer budget-friendly ceiling fans over premium or luxury options. Even in the luxury segment, where features like BLDC motors are available, over 50% of the market still chooses standard fans due to their lower price point.
The existing limitations in modifying the aesthetics of a ceiling fan are:
1. Colour of the fan cannot be changed due to the powder-coated paint finish, which cannot be repainted without the paint layer deteriorating from high-speed rotation.
2. No add-on stickers are available to change the fan's appearance, as they would deteriorate due to high-speed rotation.
3. Body facia parts such as blades or rotor bottom cover panel are not offered as separate spare parts, making it impossible for users to change the look by replacing parts. Even if available, users won't pay more than 20% of the total fan value for aesthetic modifications.
4. Existing stationary artwork-casings have a flat bottom surface with a high peripheral profile, resulting in a bulky, aesthetically unappealing appearance that disrupts the fan's original slim structure.

It's essential to note that a convex artwork-casing structure necessitates a convex printed layer, which can be fabricated from paper, plastic, or any other printable material. This convex shape is required because the inner layer of the convex artwork-casing, exposed above the fan's rotating rotor-housing body's lower panel, is curved. The printed layer must conform to this curved shape. The convex shape artwork-casing module is mounted on the fan shaft's lower end, maintaining a 3mm gap from the rotor-housing body's lower panel.

Furthermore, the outer layer of the artwork-casing, above the printed layer, is a convex-shape transparent layer (made of glass, fiber, or other materials). The gap between these two curved layers of the artwork-casing is minimal, compact, and designed to accommodate the thin, curved printed layer. This overall structure ensures a compact, sturdy, and slim product design.

The technical advancements disclosed by the present invention overcome the limitations and disadvantages of existing and conventional systems and methods.

At present, in conventional and existing systems and methods available in the market, there are limited options available, primarily targeting kid's room fans with permanent printed designs on the rotor-housing body, resulting in a boxy and bulky appearance. These designs are not interchangeable, unlike an artwork-casing with changeable design layers.

Premium and luxury designer fans with under-light fixtures occasionally feature printed designs on the bottom cover panel (PVC sheet or light-diffuser sheet). However, these fans do not offer spare parts for replacing the printed layer with new design options, making it a costly affair. The boxy and bulky structure, combined with the high replacement cost, deters end-users from opting for design replacements.
Consequently, brands have not offered such product offerings, as the landing cost to the end-user for a similar cover panel with a printed design would be around 20-25% of the fan's cost (approximately ₹240-375 for a standard ceiling fan in India priced between ₹1200-1500). The additional costs of order processing and logistics are included in this estimate.
Given the price and affordability constraints, standard fans in the low-price range are not offered with under-light or printed design features. In this scenario, providing an affordable fan with an extra feature of a changeable printed design-layer appears unviable.
This invention overcomes the aforementioned limitations of the current market. With this invention, we can offer a slim product design featuring replaceable printed artwork-layers at a very affordable price. Notably, the replacement of the printed design layer will cost less than 5% of the fan's cost and can be easily replaced through a DIY ("do it yourself") process, eliminating the need for a technician.
We would like to emphasize that this inventive step goes beyond merely incorporating "a stationary deco-panel" or "a stationary artwork-casing mechanism" in a ceiling fan. Instead, it specifically involves structurally forming a unique convex artwork-casing module that seamlessly adapts to the fundamental structure of a ceiling fan's rotor-housing, yielding a sleek, compact, and minimalist appearance.
While others may develop similar products with replaceable printed layers, our inventive feature takes it to the next level by refining the structure to achieve a sleek and compact design. This is accomplished by adapting the fundamental structure of a ceiling fan's rotor-housing, comprising 2 ball bearings, stator with coils, rotor-housing with permanent magnet.
The inventive feature enables the inner layer of the artwork-casing structure to run almost parallel to the rotor-housing body, with a minimal gap of around 3mm to avoid friction. Similarly, the outer layer of the casing is also curved, running almost parallel to its lower layer with a negligible gap to accommodate the curved shape printed design layer. This results in a remarkably slim and compact appearance of the ceiling fan, avoiding the boxy and bulky look that would otherwise result from the addition of the artwork-casing.

SUMMARY OF THE INVENTION

The present invention relates to a system and method of structurally forming a convex artwork-casing module that adapts to the fundamental structure of a ceiling fan's rotor-housing, yielding a sleek, compact, and minimalist appearance.

In another embodiment,a process for structural formation of a convex artwork-casing module integrated into a ceiling fan is provided. The process includes of mounting a convex artwork-casing display module to an extended shaft end of the stationary assembly of a ceiling fan, wherein the stationary assembly includes a stator and shaft; opening, a release mechanism of transparent cover panel of the convex artwork-casing module; pulling out the convex printed layer from the transparent cover panel and manually installing a new convex printed layer featuring a different design onto the transparent cover panel; closing, by a locking mechanism, convex transparent cover panel and incorporating a printed design layer, to secure to the convex artwork-casing module, thereby forming a single, complete module.

In another embodiment, a system of structural formation of a convex artwork-casing module integrated into a ceiling fan, said system includes a metal down rod configured to hang the fan from ceiling, wherein the metal down rod is connected with a motor housing to a ceiling mount, wherein the metal down rod configured to allow proper clearance and stability for the fan, wherein the motor housing is an outer casing that houses a motor of the fan; a stator fixed inside the motor housing with a plurality of coils to generate electromagnetic field; a fan shaft fixed to the stator to form a stationary component of the fan even when fan is in motion; wherein the metal down rod is connected to a fan shaft fixed below the fan rod and connected to a first Ball Bearing, wherein the shaft passes through the first Ball Bearing to further hold a stator; a second Ball Bearing connected to the lower end of the shaft and lies below the stator; a Rotor Housing Module supported by the second Ball Bearing, wherein lower end of the rotor housing module is supported by the second ball bearing and upper end of the rotor housing module is supported by the Second ball bearing, so that the Rotor Housing with permanent magnets in it rotates while fan is switched on, wherein the Rotor Housing Module includes a plurality of Fan Blades mounted on it, forming the rotatable assembly of the fan; a Convex Artwork-Casing Module affixed to lower extremity of the Shaft, wherein the Shaft passes through the second Ball Bearing and extends below the fan, wherein the convex artwork-casing module placement ensures that the lower panel of the Rotor Housing Module stays clear of the Shaft, wherein a hole is provided in its center at the second Ball Bearing position.

In another embodiment, the Convex Artwork-Casing Module comprising a Convex Printed Layer and a Convex Transparent Cover Panel.

In another embodiment, the Convex Printed Layer is situated beneath the inner layer of the Convex Artwork-Casing Module, also known as its bottom layer.

In another embodiment, the Convex Transparent Cover Panel is positioned below the Convex Printed Layer and features a locking mechanism that secures it to the Convex Artwork-Casing Module, holding the Convex Printed Layer in between.

In another embodiment, once the ceiling fan with the integrated stationary convex artwork-casing display module is installed, users replaces the printed layer at their convenience.

In another embodiment, user manually opens the Convex Transparent Cover Panel by operating its release mechanism, such as a tread structure, screw and slot, wherein the Convex Printed Layer is replaced by pulling out the layer and manually installing a Convex Printed Layer with a different design into the Transparent Cover Panel.

In another embodiment,wherein afterwards, the user closes the module by operating the locking mechanism of the Convex Transparent Cover Panel, which holds the Convex Printed Layer, to secure it to the Convex Artwork-Casing Module, thus forming a single, complete module.

In another embodiment, wherein after replacing the Convex Printed Layer, when the fan is turned on and spine, the central stationary assembly of the ceiling fan, including the complete Convex Artwork-Casing Module, remains stationary at all times.

In another embodiment, wherein a minimal gap is maintained between the inner bottom layer of the Convex Artwork-Casing Module and the adjacent lower layer of the rotating Rotor Housing Module to prevent friction and dissipate heat generated by the operating magnets.

An object of the present invention is to provide the facility to a user for changing the design & looks of a fan by replacing the printed design layer present inside the casing panel of ceiling fan.

Another object of the present invention is to provide a low-cost alternate for changing the aesthetics of the ceiling fan as the printed design layer are very low cost item.

Yet another object of the present invention is to provide a hassle-free experience, instant solution for changing the design looks of the ceiling fan without the end user being dependent on a technician or needing an electrician, in order to replace the printed design layer of the casing panel of the ceiling fan.

Another objective of the present invention is to provide a competitive edge or unique selling point for a ceiling fan brand who owns this inventive feature. This innovative fan features an artwork-cashing display, distinguishing it from similar offerings by competitors. While others may offer comparable fans with artwork-casing displays, our offering boasts a slim and sleek artwork-casing module in curve shape, unlike the boxy and bulky alternatives offered by competitor brands. Even if other brands offer similar fans at comparable prices, our product's inventive feature and attractive sleek design will likely be preferred by the majority of consumers.

Another objective of the present invention is to revolutionize the stagnant design of traditional ceiling fans. Typically, homeowners and tenants are stuck with the same outdated fan designs for years, often settling for the most basic and cheapest models with solid white or brown colors. Notably, around 50% of consumers belong to the lower middle class and middle class, who consistently opt for standard fans priced between Rs 1500 to 2000. The present invention aims to enhance the aesthetic appeal and value of these standard, low-cost ceiling fans, transforming them into visually appealing fixtures without increasing their price. Furthermore, the low production cost of the printed layer, which can be as simple as a sticker, photo paper, or thin plastic sheet, makes it an ideal solution for upgrading the design of ordinary ceiling fans.

Yet another object of the present invention is to provide a mounting and housing provision for placing a convex artwork-layer (generally a printed sheet made of paper, plastic, or other materials). The design layer can be a printed cap (facia) layer-structure that can be fixed directly to the convex artwork casing or as a printed layer placed inside the casing with a transparent holder-cap above it. Hence, when we say that it's an artwork casing, it's not limited to any specific style or technique of placing the artwork layer (printed design part). The present invention is specific about a convex-shaped artwork-casing with a convex-shaped artwork layer (printed design layer) in or on it, where the bottom layer beneath the printed layer is also convex, which is unusual & unique. This unique structural-make is required to adapt to the fundamental structure of a ceiling fan's rotor-housing module (explained later in figures), resulting in a slim and sleek look. Otherwise, with a flat bottom layer of the casing-display panel beneath the flat printed layer, it would result in a boxy and bulky look, appearing twice as thick and making the overall fan aesthetically unappealing; this kind of fan can be offered by competitors' brand if they are not able to copy our inventive feature.

Yet another object of the present invention is to provide a mounting and housing provision for placing a convex artwork-layer (generally a printed sheet made of paper, plastic, or other material) even in the case of a similar fan with a light source behind the printed design layer. In other existing fans in the market (without our inventive feature) that have an inbuilt light source, there is a printed design facia above the flat light source layer. This printed layer can also be replaced, similar to the artwork-casing structure. The only enhancement that our inventive feature brings to this kind of fan with back-light is that the inner layer of the artwork-casing beneath convex shape light source layer, being convex in shape, can accommodate a light-emitting layer within its housing, and then there is the convex outer layer of the artwork-casing (a transparent panel with a convex printed design layer in it or a printed light-diffuser panel in itself). This overall results in a very slim structure design compared to other existing similar fans in the market. Here, the convex shape bottom layer below the LED light layer plays a crucial role in achieving the required slim outlook. In contrast, existing stationary printed screens with backlighting have flat printed layers and flat LED layers, resulting in a boxy and bulky look, which is generally undesirable.

The design part is not limited to any specific method of printing, whether digital print, UV machine print, screen-applied print, hand-painted, heat transfer print, or any other kind of design application. The artwork-casing structure can be made from various materials, such as plastic, metal, or a combination of multiple materials, without being limited to any specific material. The mounting system and method of this invention are not limited to a specific mounting plate design over which the convex artwork-casing is fitted. Alternatively, if it's fixed directly to the fan shaft's lower end, the technique used can vary, such as thread, clip, screw, or any other technique. Similarly, the technique for locking and unlocking the transparent cover layer to its base module is not limited to any specific method. The invention can also be in the form of a housing module structure that holds light fixtures and a cover panel on top. Between the light fixture and cover panel, the convex design-layer can be placed. Since the ceiling fan is upside-down, the cover panel (transparent panel) can hold the design-layer. Alternatively, a printed sticker can be stuck over the cover panel (transparent panel or light-diffuser sheet itself) of this housing module of the convex casing. In conclusion, the inventive step is about the convex shape bottom layer of the artwork-casing display housing a convex shape printed layer in it, yielding a sleek and slim outlook structure of this module, adapting the fundamental structure of a rotor-housing assembly of a generic fan.

3 denotes the top ball-bearing;
4 denotes the fan blade;
5 denotes the side part of the rotor-housing module inside which the stator & coils are found;
6 denotes the bottom ball-bearing;
7 denotes the bottom part of the rotor-housing module;
8 denotes the stator, represented with dotted line, which is present inside the rotor-housing module;
9 denotes the upper part of the rotor-housing module.

Figure 4,illustrates the standard and generic dimensions of a ceiling fan's rotor housing module, essential for understanding the application of the inventive feature. While these dimensions may vary slightly across different fans, the values provided here represent the closest approximations for a typical sleek and compact ceiling fan's central assembly.
In Figure 4, various dimensions are represented with the help of numbers as explained below:
10 denotes the top side of the rotor-housing module in convex shape for which the height generally measures 20mm;
11 denotes the side part of the rotor-housing module in vertical-flat shape for which the height generally measures 25mm;

Figure 5, presents a comparative analysis of a generic fan with a flat artwork-casing module (without the inventive feature) and another ceiling fan with the inventive feature of a convex artwork-casing module. This comparison highlights the dimensional differences resulting in a slim design appearance.

In Figure 5(a), an exploded view of a generic fan with a flat artwork-casing module is shown. The assembled version of the same product is depicted in Figure 5(b). Notably, the number 13 indicates the overall height of the generic artwork-casing module, typically measuring between 50-60mm. This vertical measurement is taken from the bottom center tip of the casing module to the top end of its side profile. Consequently, the side profile of the casing module appears boxy and bulky, compromising the fan's original slim structural design.
Figure 5(c)presents an exploded view of a fan incorporating the inventive feature of a convex artwork-casing module, while Figure 5(d) shows the same fan in assembled form.
The numbers 14 and 15 in the diagram denote the following:
14 represents the height of the inventive convex artwork-casing module, measuring 30mm. This vertical measurement of the side profile enables the module to maintain a slim appearance, preserving the fan's original design.
15 represents the overall height of the inventive convex artwork-casing module, typically measuring between 50-60mm. This vertical measurement is taken from the bottom center tip of the inventive casing module to the top end of its side profile. Despite its overall height of 50-60mm, the convex shape and 30mm side profile height allow the module to retain the fan's slim appearance, avoiding a bulky or boxy look.

Figure 5(e) presents an exploded view of a generic fan with a convex shape artwork-casing module, while Figure 5(f) shows the same product in assembled form.
The primary distinction between this generic convex shape artwork-casing and the inventive convex artwork-casing lies in their dimensions. Although the generic convex shape artwork-casing may appear similar in shape, its overall height is significantly greater, measuring 70-80mm, as denoted by the number 17 mark. In contrast, the height of the side profile of the same casing module measures 50-60mm, indicated by the number 16 mark.
Notably, despite resembling the inventive feature in shape and appearance, the generic convex shape artwork-casing module results in a bulkier and boxier overall design. This is evident when compared to Figure 5(a) and (b), which illustrate the height of the generic artwork-casing flat module.

Figure 6presents an exploded view of the inventive feature, showcasing the various components in detail. In Figure 6(a), the components are labelled with numbers, as explained below:

18 denotes the rotor-housing module of the ceiling fan, which houses the stator.

The shaft may have a threaded surface for accommodating the fitting of the artwork-casing module. It is essential to note that the inventive feature does not pertain to the extended fan shaft or its threaded surface. The inter-locking of the shaft end and the artwork-casing module is not limited to threaded structures, screw fittings, nut-bolts, clips, etc.
20 denotes the bottom layer of the inventive convex artwork-casing module, which is fixed to the shaft, maintaining a minimal gap between the lower body part of the rotor-housing module, which moves during fan operation.
21 denotes a screw applied to the bottom layer of the inventive convex artwork-casing module to fix it to the fan shaft. It is worth noting that this can be replaced with alternative fixtures or mechanisms, such as bolts, clamps, clips, or others.
22 denotes the artwork layer, typically a printed paper or PVC sheet, convex in shape, designed to accommodate inside the inventive module structure. A flat printed design layer cannot be used due to the convex shape of both the bottom and top layers of the casing module structure, which have a negligible gap.
23 denotes the top layer of the inventive convex artwork-casing module, typically made of transparent glass, plastic, or similar materials, allowing for clear visibility of the printed design layer. This top layer serves as a closing cap, tightly holding the printed design layer in place and locking with the bottom layer of the convex artwork-casing module.
Figure 6(b) shows a side view of the inventive convex artwork-casing module with the ceiling fan in assembled form.

Figure 7presents an exploded view of the inventive feature, showcasing its various components in a slightly different form while maintaining similar structural elements. This figure demonstrates that the convex artwork-casing module can be developed in various forms and structures while retaining its core concept and intention.

In Figure 7(a), the components are labelled with numbers, as explained below:

Figure 8,showcases the versatility of the convex shape artwork-casing display module, demonstrating its adaptability to various shapes beyond the conventional circular design. This figure highlights the flexibility of the fundamental structural formation of such convex casing displays, which can be easily adapted to accommodate triangular, square, hexagonal, and other shapes.
Traditionally, fan brands have preferred circular shapes due to alignment issues between fan blades and the corners of non-circular shapes. As a result, stationary deco-panels have been limited to circular shapes. Although some fans may feature triangular or square shape central deco-modules, these modules typically rotate with the rotor and are fixed to the rotor-housing.
However, with the advent of our technology solution, which enables precise alignment of fan blades with the corners of stationary polygonal shape central panels, we are now exploring variations of triangular and square shapes for the convex artwork-casing display module.

The figure comprises four sub-figures:
Figure 8(a) a triangular shape convex artwork-casing display module with the inventive feature, before attachment to the ceiling fan's stationary assembly. Here, one can clearly observe the convex shape around the center of the triangular panel, bulging downwards, in order to accommodate the round rotor-housing assembly of the fan when being attached to it, maintaining the sleek look around its peripheral vertical profiles.
Figure 8(b) shows the same triangular convex casing display module with the inventive feature, after attachment to the ceiling fan.
Figure 8(c) illustrates a similar triangular flat artwork-casing display without the inventive feature, before attachment to the ceiling fan's stationary assembly.Here, it is evident that the overall structure of the triangular casing module is flat at the bottom. Consequently, to accommodate the round rotor-housing assembly of the fan when attached, the overall depth of the triangular display is substantially increased, nearly doubling or exceeding the depth of the one shown in Figure 8(a). This results in a bulky appearance, characteristic of a design without the inventive feature.
Figure 8(d) displays the same triangular flat artwork-casing display module after attachment to the ceiling fan.
Figure 8 primarily illustrates a comparison between the sleek and bulky appearances of similarly shaped fans, with and without the inventive feature.
