Description:FIELD OF THE INVENTION
The present invention relates to a mechanism for controlling the motion of fan blades, enabling them to come to rest in a precise alignment with a polygonal stationary central display, thereby ensuring that the fan blades assume a consistent and predetermined orientation when stationary.
BACKGROUND OF THE INVENTION
With evolving usage of display screens in all kinds of gadgets like smart phone, smart watch, TV, vehicles etc even fans have arrived in their smart versions (controlled by remote & phone app) and also will be available with display screens to give more technology driven appearance along with many other features. In cost-sensitive fan designs, integrating a smart screen may be impractical. However, a central stationary panel with a printed design or decorative casing can provide a similar aesthetic appeal at a lower cost. Throughout this disclosure, references to a "display screen" encompass not only digital displays but also decorative panels, printed designs, or other display modules. As far a round display screen is fixed to the bottom centre part of the fan (over the stationary central assembly), it is not a concern that where the fan blades stops once turned off and in which directions its blades point to; since round shape display screen is not a polygon. The moment we try a display screen which is in polygonal shapes similar to triangle, pentagon, hexagon, ditrigon etc it becomes a matter of concern that the fan blades must stop aligning with the corners (directions in which joints of the polygon shape points), instead of random directions, once the fan is turned off. Without this inventive feature, when fan blades directions are not aligned with polygon shaped display screen, fan appears to be unpleasant & disturbing to the viewer’s eyes as if something has gone wrong, malfunctioning or damaged or improperly designed product (fan). With this inventive feature, where the motion of fan blades are controlled in order to bring them in alignment with the polygon shaped display screen when fan blades stop moving, it appears to be mindfully designed and creates a harmony in itself.

8. A process for controlling the motion of fan blades, enabling them to come to rest in a precise alignment with a polygonal stationary central display, said process comprising:
detecting, by a processing unit, rotation per minute (RPM) of fan blades, wherein when the speed is turned to zero, then the plurality of blades slowly start dropping its RPM;
generating electromagnetic field by a stator fixed inside the motor housing with a plurality of coils, wherein the plurality of coils include a first set of coils and a second set of coils, wherein the first set of coils act as electromagnets;
passing, by the processing unit, power to the first set of coils of the stator of the fan in order to polarized in such a way that the permanent magnets in a motor housing get attracted to the first set of the coils and stops blades in respect to the orientation of the display screen;
pulling opposite poles of the permanent magnets of the rotor by the first set of coils of the stator when the permanent magnets come closer to the first set of coils;
activating the first set of coils only once the fan speed is turned to zero and RPM of the fan blades is below to a defined lowest RPM value; activating the first set of coils only once the fan speed is turned to zero and RPM of the fan blades is below to a defined lowest RPM value, wherein the coil set of the stator is not exclusively reserved for the aforementioned function, and wherein instead, an additional electromagnet set or similar technique is provided specifically for this purpose.
9. The process as claimed in claim 8, wherein the the placement of the fan blades over rotor in such a way that permanent magnets are aligned with at least one of the fan blades direction, wherein the placement of the display screen over stator in such a way that the direction of alignment of the first set of coils is in same direction pointed by at least one of the corner of the display screen, wherein in case of single ball bearing fan, the display screen can be fitted to the stator with or without mounting plate whereas in case of a double ball bearing fan, the display screen is fixed to the shaft lower node.
10. The process as claimed in claim 8, further comprising aligning, by bringing the fan blades to a halt in a precise direction, the blades come to rest pointing towards the corners of the polygonal-shaped display screen, due to the attractive forces between the first set of coils in the stator and the permanent magnets in the rotor.
