Description:FIELD OF THE INVENTION
[0001] The present subject matter is related, in general to a wearable device, and more particularly, but not exclusively to a wearable device for automotive and non-automotive application, and a method of manufacturing thereof.
BACKGROUND OF THE INVENTION
[0002] The current situation presents a significant dependency on a wearable device. While usage of such a wearable device, there are chances of fog being accumulated due to external environment and breathe of the user. However, the fog accumulation tends to make the user feel uncomfortable. Thus, it is important to either manually remove the fog from the wearable device, or to prevent the accumulation of fog. In an example, a helmet is a wearable device which is a mandatory wearable for a rider of the vehicle as per many existing norms and regulations across the jurisdiction. Typically, a helmet comprises a visor which protects the visibility of the rider. The visor usually comprises an inner face, and an outer face. The inner face of the visor is towards the eyes of the riders, while the outer face of the visor is towards the outer environment. While, the helmet is used in cold regions, or due to breathing of the rider, the visor tends to accumulate fog at the inner face of the visor. Further, while the vehicle is being ridden during night times the lights coming from the other vehicles, and the other sources of light on the road, tends to create a glare on the outer surface of the visor. Both the fogging and the glaring of the visor can harmfully distract the rider while riding, which can lead to major accidents.
[0003] Conventionally, the visor of the helmet is not provided with anti-fog materials, which leads to accumulation of heavy fog on the inner surface of the visor, causing major discomfort and safety risks to the rider of the vehicle. As per known state of art, the inner surface of the visors is provided with anti-fogging film which prevents accumulation of fog on the inner surface of the visor. However, such an anti-fogging film or the anti-fogging layer tends to scratch over a period of time. Moreover, such an anti-fogging film, or anti fogging layer on the inner surface of the rider darkens the vision of the rider. Thus, such a dark anti fogging film affects eyes, and could to other health issues such as headache or eye strains. Moreover, the as per another known state of art, the visors are provided with a thin layer of anti-reflective coating on the lenses. The anti-reflective coating can get scratched or worn down over time, which makes it harder for the rider to see clearly and, in turn, affects their vision. The above information disclosed in this background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

The retention mechanism may be a strap that can be tightened around a lower chin of the user’s head 10.
[00025] In the illustrated embodiment, the helmet 100 includes a visor 112. The visor 112 is rotatably attached to the shell 110 in such a manner that the visor 112 may be opened or closed as per user discretion. The visor 112 is transparent and allows the user to see outside of the helmet 100 while wearing the helmet 100. The visor comprises an inner face 112A and an outer face 112B. The inner face 112A and the outer face 112B are composed of a first material, and the outer face is composed of a second material. The first material has a fog resistant attribute and the second material have an anti-glare attribute. The first material is composed of polyvinyl alcohol - tris buffered saline based surfactant silicon dioxide at a predetermined ratio, wherein such composition enables the antifogging property on the inner face of the visor. The first material is SilFort TAC 2000. The second material being made of magnesium fluoride and fluro polymer at a second predetermined ratio to enable anti-glare attribute of the outer face. The visor is manufactured by a moulding process, wherein during injection moulding first material being added to a base material at a predetermined temperature to achieve fog resistant attribute of the first material. As per an embodiment the base material is composed of poly Carbonate or polymethyl ‐methacrylate.

The method comprises the steps of fitting, a mould of a predetermined shape in a moulding machine, wherein the predetermined shape corresponds to a shape of a visor 112 of the wearable device A. After fitting the mould, a feeder of the moulding machine is filled with a mixture 204. The mixture having a first predetermined portion of a base material. The first predetermined portion being in the range of 15% to 98% by weight. After the mixture has reached a first predetermined temperature, adding a second predetermined portion of a first material to the feeder. The first material is an additive such as polyvinyl alcohol - tris buffered saline based surfactant silicon dioxide. The second predetermined portion predetermined ratio being between the range of 15% to 95% by weight. In an example, the range of first predetermined temperature is 120 degrees Celsius to 200 degrees Celsius. Thereafter, the mixture is heated at a second predetermined temperature for a first predetermined time period. The second predetermined temperature could range in between 240 degrees Celsius to 320 degrees Celsius, and the first pre-determined time period could range between the range of 20 minutes to 60 minutes. The heated mixture is force into the mould at a predetermined high pressure. For example, the predetermined high pressure could range between 5kpsi to 100kpsi.
