Description:FIELD OF THE INVENTION

The present invention relates to a system and method for providing a polygonal shape facia panel with central assembly of a uni-body design ceiling fan, providing a completely seamless and joint-free appearance at its central-bottom portion, distinguishing it from other similar uni-body design ceiling fans featuring a usual circular joint at the central assembly.

BACKGROUND OF THE INVENTION

In this evolving ceiling fan market, the fan's design has become a key decision-making factor for consumers, surpassing energy savings, cost, and air-delivery importance if the design excels. In this design-driven era, almost every brand offers uni-body and monolithic design structures, typically made of ABS (Acrylonitrile Butadiene Styrene) material, a common thermoplastic polymer valued for durability, impact resistance, and affordability, transforming ceiling fans into style statements and premium design products.

Furthermore, upon closer inspection, these fans appear remarkably similar, with negligible design variations and minute detailing differences, making it challenging for brands to establish and maintain a distinctive brand identity or design image, as competitors unveil nearly identical designs. This similarity also complicates consumer decision-making, as various brands offer slightly modified designs at different price points, rendering them virtually indistinguishable from one another.

This homogenization of designs poses a dilemma for both brands and consumers. Brands strive to maintain a distinct identity, differentiate themselves with unique offerings, and prevent competitors from replicating their successful uni-body design fans. Conversely, consumers seeking stylish, premium uni-design fans are willing to pay a premium, but want to ensure their ceiling fan isn't mistaken for a copycat design from a local brand.

Therefore, a need exists for a system and method to create a seamless, polygonal shape facia panel for uni-body design ceiling fans, featuring a joint-free, central-bottom portion appearance that differentiates it from similar fans with circular joints. This polygonal shape facia introduces a unique aesthetic, enhancing the fan's monolithic appearance and setting it apart from competitors' circular shape facia designs. Notably, the polygonal central facia is a single-piece, joint-free construction, eliminating the circular joint and achieving a 100% single-piece look.

The present invention's technical advancements overcome the limitations and drawbacks of conventional systems and methods, offering a significant improvement.

The present invention focuses on the structural design of the polygonal shape central facia in a uni-body ceiling fan, achieving a seamless and joint-free appearance at its central-bottom portion. This distinguishes it from similar uni-body design ceiling fans with circular joints. Notably, while other brands may offer similar polygonal shape central facia designs, they will typically feature a circular joint-line within the structure. In contrast, the inventive structure boasts a 100% joint-free, single-piece polygonal shape facia.

SUMMARY OF THE INVENTION

The present invention relates to a system and method for providing a polygonal shape facia panel with central assembly of a uni-design ceiling fan, providing a completely seamless and joint-free appearance at its central-bottom portion, distinguishing it from other similar uni-body design ceiling fans featuring a usual circular joint at the central assembly.

In an embodiment, a system for providing a polygonal shape facia panel with central assembly of a uni-body design ceiling fan is provided. The system comprising a metal down rod configured to hang the fan from ceiling, wherein the metal down rod is connected with a fan shaft, wherein the fan shaft is configured to hold a central rotor assembly of the fan; a central rotor assembly configured to hold a plurality of fan blades to be installed onto its shafts with firm support; a speed controller unit connected to the central rotor assembly, in order to control the speed of the fan; a polygonal shape facia panel fixed onto the plurality of fan blades surface and central rotor assembly, wherein inner side of the polygonal shape facia panel includes a plurality of nodes or teeth in order to fix firmly onto the surface of the plurality of fan blades and the central rotor assembly, in order to avoid any vibration during fan motion.

In another embodiment, wherein top side of the plurality of fan blades includes holes to fix screws or bolts, so that they can pass through the body of the fan blades, reaching the provisions on the inner surface of the polygonal shape facia, and holding it tightly, thereby avoiding vibration during fan motion.

In another embodiment, wherein the polygonal-shaped, uni-body design facia panel conceals circular joint line typically found at the central bottom assembly.

In another embodiment, surface of the facia panel is selected from flat, convex, concave or any three-dimensional (3D) projection surface design.
In another embodiment, outer shape of the polygonal-shaped facia is designed with sharp corners, rounded corners, or a completely rounded structure.

In another embodiment, the inner side of the fixture includes a plurality of nodes and teeth structures that engage with corresponding grooves on the fan's body surface, enhancing grip and interlocking.

In another embodiment, the inner surface configured to incorporate provisions for screw and bolt accommodation, facilitating secure attachment of the facia to the ceiling fan assembly.

In another embodiment, a method for providing a polygonal shape facia panel with central assembly of uni-body design ceiling fan is disclosed. The method comprising of installing a plurality of fan blades to a central rotor assembly of the uni-body design ceiling fan, wherein the fan configured to accommodate a polygonal-shaped facia panel; placing the polygonal-shaped facia panel onto the fan surface, effectively concealing circular joint-line at central bottom portion of the fan assembly; plugging the polygonal-shaped facia panel into portion of the ceiling fan assembly, wherein nodes or teeth structure on inner side of the facia panel securely engaged with corresponding groove provision on the fan's surface, ensuring a firm interlock and grip, wherein screws and bolts are applied from the backside of the fan assembly to rigidly hold the facia panel; tightening the screws and bolts, ensuring the polygonal-shaped facia panel is firmly and securely attached to the ceiling fan assembly.

In another embodiment, top side of the plurality of fan blades includes holes to fix screws or bolts, so that they can pass through the body of the fan blades, reaching the provisions on the inner surface of the polygonal shape facia, and holding it tightly, thereby avoiding vibration during fan motion.
In another embodiment, outer shape of the polygonal-shaped facia is designed with sharp corners, rounded corners, or a completely rounded structure.

Yet another object of the present invention is to offer a unique uni-body and monolithic design ceiling fan integrating a polygonal shape single-piece facia. This conceals the ordinary circular joint-line at the central bottom portion of the fan, establishing and representing a cutting-edge, futuristic design look to stand out in the market among consumers.

Another objective of the present invention is to develop a uni-body ceiling fan design featuring a polygonal shape single-piece facia panel, which conceals the usual circular joint-line found in such ceiling fans.

Another objective of the present invention is to develop a structure of the polygonal shape single-piece facia panel designed in such a way that when it's placed on the assembled ceiling fan's central portion, its central portion hides the circular joint-line of the central assembly and blades, and its outer corners overlap the blades' parts as well.

Another objective of the present invention is to develop a structure of the polygonal shape single-piece facia panel developed in a 4-piece make, with negligible or zero-tolerance joining lines, which appear as a single-piece structure only from a certain distance when viewed. Hence, the polygonal shape facia is in a single-piece make or in a multiple-piece construction with negligible joint lines to make it appear as a single piece, both ways result in the desired structure that ultimately hides the usual circular joint line at the center and gives a new kind of unique polygonal shape single-piece look, which is intended here.

Another objective of the present invention is to develop bottom edge of the polygonal shape single-piece facia panel, which includes projections like teeth, which fit into grooves on the surface of the fan blades (acting like a male-female plug-in). This holds a grip on each other and avoids any vibration during the motion of the ceiling fan, even at high speed. Alternatively, instead of teeth-like projections, the facia can have a uniform vertical projection that fits firmly into the groove on the blades' surface, ensuring 100% blockage of air passage through it and zero vibration. Not limited to the above-mentioned two ways of placing together, the facia can have similar teeth or nodes anywhere else on its lower body layer for the same purpose of holding firmly together. Alternatively, one can decide to have no such teeth or projections at all and simply rely on multiple screws and bolts to hold the facia together with the ceiling fan. Having teeth, nodes, or uniform projections may provide extra grip and durability for better performance, but this does not limit the inventive feature to any specific style of mounting it together. Moreover, there can be all of these provisions together, such as teeth, nodes, grooves, and screw-fitting provisions, altogether.

Another objective of the present invention is to develop assembly of the polygonal shape single-piece facia panel onto the ceiling fan assembly, i.e., fan blades along with the central rotor assembly, is not limited to any specific technique. In general, multiple screws or bolts are applied from behind the fan blades in order to hold the provisions on the lower surface of the facia panel, so that from the outside, a viewer cannot find any screw or bolt head, concealing it completely. Alternatively, the screw or bolt fitting technique can be avoided by opting for a different locking mechanism, such as push-pin or slots-slide-in etc. Thus not limiting the inventive feature to any particular mounting technique.
