COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it
is to be performed.

TECHNICAL FIELD
[0001] The present subject matter relates, in general, to an enclosure to be
embedded in a tire of a vehicle and, particularly but not exclusively, to an enclosure to be embedded in a tube type tire of a vehicle for encasing various electronic devices measuring various tire parameters.
BACKGROUND
[0002] Vehicle behavior is directly influenced by tire characteristics. Generally,
electronic devices are incorporated in a tire of a vehicle for measuring various parameters of the tire. These parameters may include but not limited to tire pressure, tire positioning w.r.t longitudinal, radial and lateral (X, Y, Z axis) directions with the help of gyroscope sensor, internal temperature of the tire, internal humidity of the tire, angular acceleration and deceleration of the tire, load on the tire, speed of rotation of the tire, distance travelled by the tire, traction of the tire, various types of failure of the tire, and events, such as wear, breaking acceleration and deceleration etc., of the tire. Measurement of these parameters is critical to the performance of the vehicle, optimizing fuel efficiency or driver’s actions in certain situations. Accordingly, the electronic devices measuring the tire parameters must be properly secured to the tire throughout the movement of tire, since improper responses from these electronic devices may adversely affect the vehicle behavior. In a tube type tire, these electronic devices are generally incorporated between the tire and the rim.

DETAILED DESCRIPTION
[0010] The present subject matter relates to aspects relating to maintaining
attachment of electronic devices to a tube type tire by providing an enclosure to be
embedded in the tube type tire for encasing the electronic devices, wherein the
electronic devices are incorporated in the tire for measuring various tire parameters.
[0011] During movement of a tire, various dynamic forces act upon the tire.
Consequently, these dynamic forces also act upon electronic devices installed in the tire for measuring various parameters associated with the tire. The electronic devices are either permanently anchored to the tire making the electronic devices not serviceable or removably attached to the tire for facilitating serviceability of the electronic devices. Under influence of the dynamic forces that act upon the electronic devices due to movement that the tire undergoes and because of the removable nature of the electronic devices, there is a possibility of the electronic devices to popping out from within the tire. Further, the movement of the tire may cause not only detachment but also displacement of the electronic devices within the tire.

[0012] Detachment or displacement of the electronic devices leads to improper or
discontinued operation of the electronic devices and may sometimes cause damage to the electronic devices. Accordingly, these electronic devices must be incorporated in the tire in such a manner that these electronic devices can withstand the forces that act upon these electronic devices due to any movement that the tire undergoes and should not be allowed to detach from or displace within the tire.
[0013] Further, the orientation of the electronic device needs to be aligned with
the axis of the tire to accurately measure a parameter associated with the tire. For example, sensitivity of accelerometer and gyroscope with respect to the movement of their position is high. A 180-degree shift in the electronic device (upside down placement) can cause a significant deviation in the measurements of these electronic devices. Mis-orientation of the accelerometer and gyroscope due to the wrong placement of these electronic devices can disrupt all measurement references. The movement of the tire and the forces acting on the tire or on the electronic devices may lead to displacement of the electronic devices or change in orientation of the electronic devices which results in deviation in the measurements performed by the electronic devices which in turn leads to an inefficient vehicle performance. Errors in the measurements of various tire parameters performed using the electronic devices installed in the tire, need to be minimized for optimized performance of a vehicle and therefore, maintaining the orientation of the electronic devices is also a primary consideration in an installation process when these electronic devices are installed in the tire and during the dynamic movement of the tire.
[0014] In conventional designs, generally recesses are provided within the tire to
snap fit the electronic device in appropriate orientation and in a removable manner. However, these designs require recesses to be formed in the tire and thus, cannot be suited to all tires or all electronic devices. Also, skilled labor is required for the fitment of the electronic device within the tire. In other designs, either some clips or hooks and other additional components are required to removably insert the electronic device

within the tire. Although, these designs may provide snap fit of the electronic device in a particular orientation and in a removable manner, these designs are still susceptible to the risk of detachment/displacement of the electronic devices from /within the tire under the influence of dynamic forces acting on these devices or change in orientation of these electronic device because of dynamic movement and flexible nature of the tire.
[0015] Referring to Figure 1, a conventional design of an enclosure 100 to be
embedded in a tire of a vehicle for encasing various electronic devices and securing attachment of these electronic devices to the tire is illustrated. The enclosure minimizes the risk of detachment/displacement of the electronic devices from /within the tire under the influence of dynamic forces or change in orientation of these electronic device because of dynamic movement and flexible nature of the tire that are associated with the other conventional designs available for incorporating electronic devices in tires of vehicles.
[0016] The enclosure 100 to be embedded in the tire of the vehicle as illustrated
in Figure 1, comprises a housing portion 101 and a cover portion 102. Figures 1a and
1b illustrate schematics of the housing portion 101 and the cover portion 102,
respectively, of the enclosure 100. The housing portion 101 comprises a base 103 and
side walls 104 along the periphery of the base 103. Three grooves 105 (105-1, 105-2,
105-3) are provided in the side walls 104 at an equal angular distance. The cover
portion 102 has a flat surface 109 and three protrusions 110 (110-1, 110-2, 11-3) are
located at a circumferential edge of the flat surface 109. The three protrusions 110
correspond to the three grooves 105 on the side walls 104. The housing portion 101 is
fixedly attached to the tire. The cover portion 102 is removably attached to the housing
portion 101 by insertion of the three protrusions 110 into the three grooves 105.
[0017] The base 103 of the housing portion 101 extends beyond the periphery of
the base 103 where the side walls 104 are located. The extended portion 107 of the base 103 comprises orientation guidance markings, for example, a pair of projections

108 located at a peripheral edge of the extended portion 107 to enable attachment of the housing portion 101 to the tire at the center of the tire. One or more electronic devices 112 and one or more batteries 113 are mounted on the flat surface 109 of the cover portion 102 of the enclosure 100. The engagement of the protrusions with grooves in the conventional design of the enclosure 100 illustrated in Figures 1, 1a and 1b minimizes the risk of detachment/displacement of the electronic devices from /within the tire under the influence of dynamic forces or change in orientation of these electronic device because of dynamic movement and flexible nature of the tire that are associated with the other conventional designs available for incorporating electronic devices in tires of vehicles.
[0018] While the above-explained conventional design of the enclosure 100 to be
embedded in a tire of a vehicle, as illustrated in Figures 1, 1a and 1b, works well in providing a robust and stable enclosure in tubeless tires, however, placing the electronic devices between the tube and tire is challenging in tube type tire. Electronic devices such as sensors are highly prone to damage as it is getting sandwiched between the tube and the tire, and experience very high forces from the tube. Further, any protrusion in the design of the enclosure may damage the tube in dynamic condition. The design of the enclosure illustrated in Figure 1 is such that the one or more electronic devices mounted on the flat surface 109 of the cover portion 102 may protrude out from the housing 101. When the enclosure 100 is placed between the tire and the tube in a tube type tire, the one or more electronic devices and batteries protruding out from the housing 101 of the enclosure 100 may damage the tube during the movement of the tire and electronic devices 112 are also susceptible to the risk of damage because of the pressure exerted on these devices in dynamic condition. Also upper circumferential edge of the side walls 104 of the housing 101 facing the tube can cause the damage to the tube under pressure.
[0019] In accordance with an embodiment of the present subject matter, an
enclosure to be embedded in a tube type tire of a vehicle for encasing various electronic

devices and ensuring proper orientation of these electronic devices within the tire is described in the present subject matter. In an embodiment, the enclosure overcomes the above-described problems associated with the conventional designs available for incorporating electronic devices in tube type tires of vehicles.
[0020] In an embodiment, an enclosure to be embedded in a tube type tire of a
vehicle may include a housing portion and a cover portion. The cover portion has a flat surface and comprises one more electronic devices on the flat surface. The enclosure also comprises an encapsulating member to encapsulate the cover portion. The housing portion is fixedly attached to the tire. The encapsulating member with the cover portion encapsulated therein is removably attached to the housing portion. The encapsulating member has a smooth exterior surface to interface with a tube inside the tube type tire.
[0021] According to the present subject matter, the encapsulating member
encapsulates the cover portion having the electronic devices mounted and has a smooth exterior surface that interfaces with the tube when the enclosure is placed between the tube and the tire. This obviates the possibility of the tube getting damaged from any protrusion in the enclosure or the electronic devices getting damaged because of the pressure exerted by the tube on the enclosure during movement of the tube type tire on the road surface.
[0022] Furthermore, the housing member is fixed to the tire and the encapsulating
member with the cover portion encapsulated therein can be removably attached to the housing portion. Thus, easy removability of the electronic devices mounted on the cover portion is achieved maintaining the stability of the attachment of the electronic devices to the tire. Also, as will be apparent from the subsequent description, the attachment of the housing member to the tire as well as the attachment of the encapsulating member encapsulating the cover portion with the housing member is such that the electronic devices measuring the tire parameters do not get

detached/displaced owing to the dynamic forces because of movement and flexible nature of the tire.
[0023] The above and other features, aspects, and advantages of the subject matter
will be better explained with regard to the following description and accompanying figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter along with examples described herein and, should not be construed as a limitation to the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the principles of the present disclosure. Moreover, all statements herein reciting principles, aspects, and examples thereof, are intended to encompass equivalents thereof. Further, for the sake of simplicity, and without limitation, the same numbers are used throughout the drawings to reference like features and components.
[0024] Figure 2 illustrates an enclosure 200 to be embedded in a tube type tire (not
shown) of a vehicle (not shown), in accordance with an implementation of the present subject matter.
[0025] Referring to Figure 2, the enclosure 200 to be embedded in the tire of the
vehicle, in an implementation of the present subject matter, comprises a housing portion 300, an encapsulating member 400 and a cover portion 500. The housing portion 300 , in one example, is similar to the above-explained housing portion 101 described in context of Figures 1, 1a and 1b. The encapsulating member 400 encapsulates the cover portion 500. Details of the encapsulating member 400 have been elaborated subsequently. The cover portion 500 is similar to the above-explained cover portion 102 described in context of Figures 1, 1a and 1b, in an example implementation. As will be understood the cover portion 500 comprises the sensors 502. The housing portion 300 is fixedly attached to the tire. The encapsulating member 400 encapsulates the cover portion 500 such that the components, such as the sensors 502 or batteries 503 that may be protruding from the cover portion 500 are sealed

within the encapsulating member 400. The encapsulating member 400, with the cover
portion 500 encapsulated therein, is removably attached to the housing portion 300.
Since the encapsulating member 400 has a smooth exterior surface, it will interface
with a tube inside the tube type tire allowing the tube to sit smooth along the
encapsulating member without facing any of the above-described technical problems.
[0026] Figure 3 illustrates schematics of a housing portion 300 of the enclosure
200, in accordance with an implementation of the present subject matter. As illustrated in Figure 3, the housing portion 300 may comprise a base 301 and side walls 302 along the periphery 303 of the base 301. Three grooves 304 (304-1, 304-2, 304-3) are provided in the side walls in an angular direction. The shape of the housing portion 300 can be any one of circular, triangular, square, rectangular, oval or any other shape that can hold grooves 304. In an example embodiment, the sidewalls 302 of the housing portion 300 are slanted. The slanted profile of the sidewall 302 of the housing portion 300 provides a smooth surface to interface with the tube inside the tube type tire.
[0027] Figure 4 illustrates a cover portion 500 of the enclosure 200, in accordance
with an implementation of the present subject matter. The cover portion 500 as illustrated in Figure 4 comprises three protrusions 501 (501-1, 501-2, 501-3) located at a circumferential edge of the flat surface 504 of the cover portion 500. The three protrusions 501 (501-1, 501-2, 501-3) correspond to the three grooves 304 (304-1, 304-2, 304-3) on the side walls of the housing portion 300. The shape of the cover portion 500 can be any one of circular, triangular, square, rectangular, oval or any other shape that can cover the base 301 of the housing portion.
[0028] Figures 5a and 5b illustrate perspective views of a top portion 401 of an
encapsulating member 400 of the enclosure 200 from different angles and Figure 5c illustrates perspective view of a base portion 402 of the encapsulating member 400 of the enclosure 200, in accordance with an implementation of the present subject matter.

[0029] As depicted in Figures 5a and 5b, the encapsulating member 400 comprises
a top portion 401 and a base portion 402. The base portion 402 is removably attached to the top portion 401. Referring to Figure 5a, the top portion 401 comprises a tapered surface 404 protruding upward from the periphery of the top portion 401 to provide the smooth exterior surface to interface with the tube. The shape of the top portion 401 can be any one of circular, triangular, square, rectangular, oval or any other shape that can encapsulate the cover portion 500 of the enclosure 200 and can be removably attached to the housing portion 300. The top portion 401 also comprises three recessed flanges 403 (403-1, 403-2, 403-3) extending from the periphery of the top portion 401. The three recessed flanges 403 (403-1, 403-2, 403-3) correspond to the three protrusions 501 (501-1, 501-2, 501-3) of the cover portion 500. The three protrusions 501 (501-1, 501-2, 501-3) of the cover portion 500 are removably inserted into the three recessed flanges 403 of the top portion 401 of the encapsulating member 400 and the base portion 402 of the encapsulating member 400 as illustrated in Figure 5c is removably attached to the top portion 401 to encapsulate the cover portion 500 inside the encapsulating member 400. In an example, the interior surface of the top portion 401 facing the cover portion 500 is provided with a honeycomb structure to provide the strength to the encapsulating member 400 to withstand the pressure and force exerted on the enclosure 200 during movement of the tire on the road surface. This also protects the electronic devices 502 mounted on the cover portion 500 encapsulated inside the encapsulating member 400 from being damaged on the application of pressure.
[0030] The three grooves 304 of the housing portion 300 have a poka-yoke
arrangement for insertion of a recessed flange 403 from amongst the three recessed flanges 403 (403-1, 403-2, 403-3) in a corresponding groove from amongst the three grooves 304. The poka-yoke arrangement is implemented by providing the size of one of the three grooves 304 (304-1, 304-2, 304-3) and one of the three recessed flange 403 (403-1, 403-2, 403-3) larger than the size of other grooves and other recessed

flanges. The poka-yoke arrangement ensures that each of the three recessed flange 403 (403-1, 403-2, 403-3) is coupled to the corresponding groove 304 of same size only, when the encapsulating member 400 with the cover portion 500 encapsulated therein is removably attached to the housing portion 300.
[0031] In an embodiment of the present invention, one or more batteries 503 may
be mounted on the flat surface 504 of the cover portion 500 of the enclosure 200. The one or more batteries 503 serve as a power source for the one or more electronic devices 502 mounted thereon. Easy engagement/disengagement of the recessed flanges 403 (403-1, 403-2, 403-3) on the encapsulating member 400 with/from the grooves 304 (304-1, 304-2, 304-3) in the housing portion 300 facilitates serviceability of the electronic devices 502 mounted on the cover portion 500 encapsulated inside the encapsulating member 400. This also makes the batteries 503 mounted on the cover portion 500 easily replaceable.
[0032] In an implementation of the present subject matter, the housing portion 300
is attached to a center of a tire. Attachment of the housing portion 300 to the center of
the tire in turn leads to an attachment of the encapsulating member 400 and in turn the
cover portion 500 to the center of the tire because of the poka-yoke arrangement and
consequently facilitates alignment of the electronic devices 502 mounted on the cover
portion 500 to the center of the tire. The alignment of the electronic devices 502 at the
center of the tire is needed as maximum contact length of the tire with the ground is
detected through the electronic devices 502 like accelerometer, when such electronic
devices 502 are aligned exactly at the center of the tire or close to the center of the tire.
This in turn improves the accuracy of the results of the electronic devices 502.
[0033] In an example implementation, the housing portion 300 may be provided
with orientation guidance markings to enable attachment of the housing portion 300 to the tire at the center of the tire. Accordingly, in one embodiment, the base 301 of the housing portion 300 extends beyond the periphery of the base 301 where the side walls 302 are located. The extended portion 305 of the base 301 comprises orientation

guidance markings 306 to enable attachment of the housing portion 300 to the tire at the center of the tire.
[0034] In an example, the extended portion 305 comprises a pair of projections
306 located at a peripheral edge of the extended portion 305. This pair of projections 306 serves as orientation guidance markings to enable attachment of the housing portion 300 to the tire at the center of the tire. In another example, orientation guidance markings may be arrow heads or dots engraved or any similar identifier engraved, embossed or otherwise created on the extended portion 305 of the base 301 of the housing portion 300 at the position corresponding to the pair of projections 306. In yet another example, it is also possible to have orientation guidance markings painted on the extended portion 305 of the base 301.
[0035] Further example embodiments, where the orientation guidance markings
are provided on the base 301 of the housing portion 300as opposed to the extended portion 305 of the base 301, are also possible. For instance, orientation guidance markings, in the form of a pair of, say red dots, may be painted on the base 301. As will be understood, a position of such orientation guidance markings provided at the base 301 of the housing portion 300 corresponds to the position of the pair of projections 306 provided on the extended portion 305 of the base 301 of the housing portion 300 as shown in the Figure 3.
[0036] While attaching the housing portion 300 on the tire, the pair of projections
306 enable alignment of center of the housing portion 300 with the center of the tire. In an example embodiment, the center of the tire can be indicated through a marking specified along a centerline of the tire which is situated at a midpoint across the width of the tire. In an example, these markings can be specified in the form of dotted or solid colored lines painted along the centerline of the tire. In another example, these markings may be dots or any similar identifier engraved, embossed or otherwise created on the centerline of the tire. The orientation guidance markings on the extended portion 305 of the base 301 of the housing portion 300 are aligned with the marking

specified at the centerline of the tire, when the housing portion 300 or the enclosure 200 is attached to the tube type tire. Thus, once housing portion 300 of the enclosure 200 is aligned with the center of the tire, a predefined alignment of the encapsulating member 400 having the cover portion 500 encapsulated therein and in turn that of the electronic devices 502 mounted on the cover portion 500 is also achieved owing to the poka-yoke arrangement for attachment of the encapsulating member 400 with the housing portion 300.
[0037] In an example, the three grooves 304 (304-1, 304-2, 304-3) may be located
at an angular displacement of degree. The equal angular displacement of the three grooves 304 (304-1, 304-2, 304-3) with each other ensures that the encapsulating member 400 with the cover portion 500 having the electronic devices 502 mounted thereon does not get misplaced or pop out of the housing portion 300 due to the deformation of the tire. This in turn protects the electronic devices 502 from getting damaged. In another exemplary implementation, the dimension of the enclosure 200 including the diameter of the housing portion 300 and length of the pair of projections 306, if these projections 306 are provided as orientation guidance markings on the extended portion 305 of the base 301, may be 85.4±0.2. Further, the diameter of the cover portion 500 may be 59.5±0.2.
[0038] In an embodiment, the housing portion 300 can be fixedly attached to the
tire using an adhesive. In other embodiments, the housing portion 300 can be fixedly attached to the tire by providing cavity inside the tire and inserting the enclosure 200 in the cavity.
[0039] The encapsulating member 400 with the cover portion 500 encapsulated
therein is removably inserted to the housing portion 300 of the enclosure 200 in such a way that each recessed flange 403 (403-1, 403-2, 403-3) on the encapsulating member 400 and thereby each protrusion 501 (501-1, 501-2, 501-3) on the cover portion 500 encapsulated inside the encapsulating member 400 is engaged in the corresponding groove 304 (304-1, 304-2, 304-3) of the equivalent size. With such

poka-yoke arrangement, the electronic devices 502mounted on the cover portion 500 are installed in the tire only in a predefined orientation, which enables the alignment of the electronic devices 502 in line with the axis of the tire. Thus, x, y and z- axis of the electronic device 502 are aligned with the corresponding x, y and z- axis (tangential, lateral and radial directions respectively) of the tire for accurate and reliable measurement of tire parameters measured by the respective electronic device 502. For example, a three axis accelerometer is mounted on the flat surface 504 of the cover portion 500 as an electronic device 502 for three axis measurement of the acceleration, with the x-axis measuring the tangential, y-axis measuring the lateral and z-axis measuring the radial acceleration of tire. In this case, since the accuracy of the measured tangential, lateral and radial acceleration of the tire highly depends on the alignment of coordinates of the electronic devices 502 with that of the tire, any misalignment of the axis of the electronic device 502 with that of the tire may lead to incorrect results. The misalignment of the electronic device 502 with that of the tire may happen due to movement and flexible nature of the tire and attachment of the electronic device 502 to the tire in an incorrect orientation. This problem of inaccurate measurement of tire parameter, such as acceleration due to the misalignment of the electronic device 502 with that of the tire is addressed through the herein-explained design of the enclosure 200 to be embedded in the tire for encasing the electronic devices 502. The orientation guidance markings provided on the extended portion 305 of the base 301 of the housing portion 300 of the enclosure 200 ensures that the housing portion 300 is attached to the center of the tire in the predefined orientation to further facilitate the attachment of the cover portion 500 encapsulated in the encapsulating member 400 in the same orientation. Further the poka-yoke arrangement ensures that the coordinates of the electronic device 502mounted on the cover portion 500 of the enclosure 200 is aligned exactly with the axis of the tire, when the encapsulating member 400 having the cover portion 500 encapsulated therein is attached to the housing portion 300. The poka-yoke arrangement also ensures that the

alignment of the electronic devices 502 is maintained during the movement of the tire. As no misalignment of the electronic devices 502 with that of the tire happens, the errors in the measurements performed through these electronic devices 502 are minimized.
[0040] In an embodiment, the base 301 of the housing portion 300 can be hollow.
The hollow base 301 of the housing portion 300 reduces the weight of the enclosure
200 and also does not create additional heat and pressure which can otherwise let the
encapsulating member 400 and correspondingly the cover portion 500 having the
electronic devices 502 to pop out from the enclosure 200. Thus, it helps to maintain
the pressure equilibrium and prevent heat built up within the enclosure 200, which
prevent the encapsulating member 400 and consequently the cover portion 500 having
the electronic devices 502 mounted thereon to pop out from the housing portion 300.
[0041] In another embodiment, the housing portion 300 of the enclosure 200 may
be made up of rubber. A common rubber, for example, butyl rubber may be used for making the housing portion 300 of the enclosure 200 to be embedded in the tube type tire. Alternatively, the housing portion 300 of the enclosure 200 may be made up of the same material as that of the tire. Hence, there is no requirement of introducing any foreign material (plastic or like substrates) within the tire. Other alternative materials that can be used for this purpose include but not limited to Bromobutyl Rubber- 80-100, Natural Rubber- 0-20, Tackifier- 6-8, Carbon Black- 65-75, Zinc Oxide- 2-4, Stearic Acid- 1-2, Stearic Acid- 1-2, Accelerator MBTS- 1-2, MGO- 0-0.5, SULPHUR- 0-0.75 (All ingredients are in parts per hundred of rubber (PHR)). Manufacturing housing portion 300 of the enclosure 200 with the rubber or the like material aids in easy installation of the enclosure 200 within the tire. This also aids in easy insertion/removal of the encapsulating member 400 of the enclosure 200 in/from the housing portion 300 which is fixedly attached to the tire. This in turn facilitates the easy serviceability of the one or more electronic devices 502 mounted on the cover portion 500 encapsulated inside the encapsulating member 400 and easy replaceability

of the one or more batteries 503 mounted on the cover portion 500. Further, use of the
rubber in making of the housing portion 300 of the enclosure 200 also avoids the
possibility of popping the encapsulating member 400 and correspondingly the cover
portion 500 having the electronic devices 502 mounted thereon out of the housing
portion 300 because of the dynamic movement and flexible nature of the tire.
[0042] In an example, the encapsulating member of the enclosure is made of
plastic, for example, PEEK (Polyether ether ketone) to provide the strength to the
encapsulating member. This avoids the possibility of deformation of the electronic
devices in the event of pressure exerted by the tube on the electronic devices.
[0043] In an embodiment, the electronic devices 502 are potted to avoid
electrostatic discharge (ESD) related risk during replacement of the one or more
batteries. Since servicing is generally done manually, there is a risk of electro-static
discharge (ESD) because of the human contact, which could damage the electronic
devices 502. Thus, the electronic devices 502 are potted to provide protection from
static discharge which may happen due to human contact during servicing or
replacement of the one or more batteries 503. Accordingly, in an embodiment,
