The present invention relates broadly to the mechatronics engineering with its application to be used in footwear manufacturing. More specifically, it pertains to a footwear with adjustable heel height.
BACKGROUND
[002] The background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] High heel is a necessary part in every women wardrobe. Most of the time
while going for party or special occasion, it becomes an affinity of most of the women to use
high heels as they feel incomplete without wearing such stuff. On one side it looks pretty nice
on women but on the other side high heels often lead to a problem when it comes to running
or walking fast. If a woman wearing such high heels have to suddenly run or any other
emergency occurs like attack, fire alarm etc. it hinders and reduces her speed of running.
Also, sometimes it happens that while normal walking, it creates a problem of sprain.
[004] It is also a fact that high heels are bad for health and comfort but this barely
stops women from wearing them. Women often make sacrifices of personal comfort for
fashion. Studies have shown that these towering footwears can be costly in more ways than
one in the long run, taking their toll on your spine, hips, knees, ankles and feet, while altering
your posture and gait. High heels often lead to pain in feet if worn for longer periods of time.
[005] Had there been such footwear where the height of the heels can be adjusted, it
would have been a great help to women so that only one pair of heels can be used with increased height as well as with decreased height in some emergency situations where a woman needs to walk comfortable or to run. Limitations in existing technologies
[006] There is some amount of research being done in bringing this concept out for
making adjustable heels. But the literature survey shows that the available system for modifying the height of heels are too complex in terms of involved components. As an example, in order to provide a facility for modifying the height of heel, United States Patent number US 8,322,053 B2 discloses a folding mechanism of the heel which is to be adjusted

manually. So, whenever a woman wishes, she can fold the heel accordingly and use. But it involves a manual operation for modifying the height of heel which could be time consuming and moreover involves a physical effort.
[007] United States Patent number US 2015/0157087 Aldisclosed an introduction of
mobile application configured to modify the heel height as per the user requirement. For modifying the height of heels, it has used a telescopic arrangement fitted nearby sole area. The telescopic arrangement is in communication with a mobile phone via a controller. User can operate mobile for modifying the heel height. But since the telescopic arrangement is although reducing the weight of overall footwear, the telescopic arrangement is not surrounded by any means which can cause corrosion or can harm the machinery by dust. Moreover, too many components are involved for achieving the object which increases the cost of production also.
[008] There is therefore a need in the art for height adjustable footwear that seeks to
overcome or at least ameliorate one or more of the above-mentioned problems and other limitations of the existing solutions and utilize techniques, which are robust, accurate, fast, efficient, cost effective and simple.

[0052] FIGs. 1A through 1C illustrates exemplary representations of a height
adjustable footwear in accordance with an embodiment of the present disclosure.
[0053] The present invention discloses a footwear (9) with an adjustable heel (10)
wherein the components can be placed at appropriate place as shown in FIG. 1A. The
adjustable heel (10) comprises of below mentioned components: A control unit (1) with a
communication module; A motor (2); A battery (3); An adjustable material (4); A jack (5)
and; A wire (6).

Working of the invention:
[0054] The whole arrangement is appropriately placed in the heel (10). The said
control unit (1) is configured to provide either of clockwise or anti-clock wise rotational signal to a motor (2) via wire (6). The said motor (2) is further connected with a mini screw-jack (5) at its shaft in such a way that whenever a clockwise rotational signal is provided by control unit (1), the motor (2) rotates the connected mini screw-jack (5) in clockwise direction thereby expanding the mini screw-jack (5) and hence increasing the height of the heel (10) up to desired height level within the permissible higher height of the mini screw-jack (5). Also, whenever an anti-clockwise rotational signal is provided by control unit (1), motor (2) rotates the connected mini screw-jack (5) in anti-clockwise direction thereby contracting the mini screw-jack (5) and hence decreasing the height of the heel (10) up to desired height level within the permissible lower height of the mini screw-jack (5).The heel is adjusted to modify the height of the heel in the range of 2-4 inches which can further be extended or lowered.
[0055] FIG. IB shows the increased height of the heel (10) when clockwise
rotational signal is provided to the motor (2) by the control unit (1). The control unit (1) is further embedded with an appropriate communication module so that it can communicate with a mobile (7) via a wireless communication link (8). Alternatively, the communication module may be an additional chip which is not integrated in the control unit (1) chip. The said communication module (not shown) accordingly converts the obtained signal from the mobile (10) into appropriate signal to be used further by control unit (1) for either increasing or decreasing the heel (10) height.
[0056] In an embodiment, the control unit can receive one or more signals from a
mobile (7) to generate:
(1) Clockwise rotational signal;
(2) Anticlockwise rotational signal;
(3) Transmit the clockwise rotational signal to the communication module as per user desire;
(4) Transmit the anticlockwise rotational signal to the communication module as per user desire.
[0057] Such signal is provided to the communication module (not shown) via a
suitable communication link (8). The communication link can suitably be Wi-Fi, Li-Fi, Bluetooth, NFC, GPS or GPRS etc. Any other used communication link will fall under the scope of this invention. The communication module receives the signal transmitted by mobile

(7) and transfers to the control unit (1). The control unit (1) processes the signal and transfers to the motor (2). Motor (2) accordingly rotates either clockwise or anticlockwise direction and the connected mini screw-jack (5) accordingly increases or decreases the height of the heel (10). Also, the application is configured to modify the height of individual heel or both heels together.
[0058] The control unit (1) and a communication module further obtains a power
supply from a rechargeable battery (3). Nearby rechargeable battery (3), a charging port (not shown) is also provided in order to recharge the battery (3) when fully discharged. An on-off switch over control unit (1) can initiate the circuit.
[0059] FIG. 1C shows the outer view of the said heel (10). All electronic and
mechanical components are herein placed in the heel (10). The outer periphery of the heel (10) is made up an adjustable material (4) whose height can contract as well as elongate along with heel (10) height. The said adjustable material (4) henceforth provides a shelter to the electronic and mechanical components placed in the heel (10) with simultaneous good view from outside.
Best mode of performing the invention:
[0060] Below are the steps of using the electronic heel (10) by using mobile (10) with
appropriate software:
1. User wears the footwear (9) and switches on the control unit (1).
2. Without providing the pressure over heel (10), user accesses the mobile (7)
and opens application.
3. User either increases or decreases the height of the heel (10) by selecting "Increase" or "Decrease" option from mobile (10) for single heel or for both heels.
4. Selected option of user is transferred in the form of signal to the communication
module (not shown) via a communication link (8).
5. Communication module (not shown) processes the obtained signal from mobile (7).
6. Communication module (not shown) transfers the signal to the control unit (1).
7. Control unit (1) processes the signal and transfer to the motor (2).
8. Motor (2) accordingly rotates either clockwise or anticlockwise direction.

9. Shaft of the connected mini screw-jack (5) also rotates accordingly which
either increases or decreases the height of the heel (10) within the maximum
and minimum permissible height of the mini screw-jack (5).
[0061] In one embodiment, the mobile application may obtain the signal from the
control unit (1) regarding the current height of both the heels (10). In another embodiment, the control unit may be provided with additional buttons and hence configured to either increases or decrease the height of the heel (10) by using buttons if user is unable to use the mobile application for any reason. Novelty, Inventive Step and Industrial Application
[0062] Novelty-The novelty of the present invention lies in developing a footwear
with adjustable heel using quite simple and less complex arrangement for adjusting heel height. The adjustable heel is covered by an adjustable material and configured to be operated from mobile application.
[0063] Inventive Step-The invention discloses a footwear with adjustable heel
wherein the heel is configured to adjust its height from ground as per requirement of the user
by using a mobile application. A mini screw-jack arrangement connected with a motor unit is
placed within a defined heel area. The motor obtains a signal from a controller placed at
suitable place nearby heel area. An additional communication module connects the controller
with mobile application. Whenever user wants to adjust the heel height, user presses button
from mobile application which signals the controller via communication module to start the
motor unit. The connected motor unit accordingly rotates the mini screw-jack arrangement to
either shift up or down the heel height from ground. The outer periphery of heel area is
surrounded by an adjustable material for an easy uplifting or down lifting of the heel area
with simultaneous protection to inner placed electrical as well as mechanical components.
[0064] Industrial Application-The present invention finds a huge application as far
as safety as well as style of the women is concerned. Moreover, it can be produced easily at large industrial scale.
[0065] Embodiments of the present disclosure may be implemented entirely
hardware, entirely software (including firmware, resident software, micro-code, etc.) or combining software and hardware implementation that may all generally be referred to herein as a "circuit," "module," "component," or "system." Furthermore, aspects of the present disclosure may take the form of a computer program product comprising one or more computer readable media having computer readable program code embodied thereon.

[0066] Thus, it will be appreciated by those of ordinary skill in the art that the
diagrams, schematics, illustrations, and the like represent conceptual views or processes illustrating systems and methods embodying this invention. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. Similarly, any switches shown in the figures are conceptual only. Their function may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually, the particular technique being selectable by the entity implementing this invention. Those of ordinary skill in the art further understand that the exemplary hardware, software, processes, methods, and/or operating systems described herein are for illustrative purposes and, thus, are not intended to be limited to any particular named.
[0067] As used herein, and unless the context dictates otherwise, the term "coupled
to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean "communicatively coupled with" over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0068] It should be apparent to those skilled in the art that many more modifications
besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms "comprises" and "comprising" should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C .... and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0069] While the foregoing describes various embodiments of the invention, other and
further embodiments of the invention may be devised without departing from the basic scope

thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
