[00031] Turning to FIGs. 1 and 2, FIG. 1 illustrates a schematic representation of a case of the proposed rib assembly depicting the position of a rib structure in the rib assembly or the case, in accordance with an aspect of the present invention. FIG. 2 illustrates a schematic representation of an internal view of a flat surface on an internal surface of a case mounting unit of the rib assembly, in accordance with an aspect of the present invention.
[00032] The rib assembly 100 includes a case 102 of a pre-defined shape. In one specific embodiment, the pre-defined shape of the case may be a cuboidal shape, but not limited to the like.
[00033] The case 102 includes a flat body 104 having a pre-defined dimension. In one exemplary embodiment, the shape of the flat body 104 may be cuboidal in nature. Further, the case 102 also includes a protruded body 106. In one embodiment, dimensions of the protruded body 106 may also be pre-defined as required. In one exemplary embodiment, the shape of the protruded body 106 may be cuboidal or semi-cuboidal in nature, but not limited to the like. The shape and dimension of the flat body 104 can be based on the dimension of an internal portion of the case mounting unit 112.
[00034] Furthermore, a top portion of the flat body 104 is coupled to a bottom portion of the protruded body 106 to provide the case body having the pre-defined shape. In one embodiment, the flat body 104 of the case body may be configured to be housed inside the case mounting unit 112. However, the height of the protruded body 106 is greater than the height of the flat body 104, such that the protruded body remains outside the case mounting unit 112 when the case 102 is inserted into the case mounting unit 112.
[00035] The case 102 further includes a beam 108 configured at a joining point of the flat body 104 and the protruded body 106, along a top surface of the flat body 104.
[00036] Furthermore, the case 100 includes a protruded section 110 of a rib structure etched along one of the side surfaces of the case body 102.
[00037] The case mounting unit 112 includes a slot 114 configured to engage with and hold the beam 108. The slot 114 and the beam 108 form the snap fit locking unit of the rib assembly 100. The slot 114 is housed on a top surface of the case mounting unit 112 synchronous to the beam 108 to enable the locking of the case 102 with the case mounting unit 112.
[00038] The case mounting unit 112 also includes a tongue 110 of the rib structure housed along one of an external side surface. Further, the case 102 is inserted into the case mounting unit 112 to assemble by press fit between rib structure 110 and the internal flat surface 116 of the body 112 and to couple the beam 108 of the snap fit locking unit to fit into the slot 114 on the case mounting unit 112.
[00039] The snap fit locking unit and the rib structure are configured to hold the case 102 upon being inserted into the case mounting unit 112 to control and eliminate rattling when the rib assembly is housed within the said device.
[00040] In one exemplary embodiment, the case mounting unit 112 may include a hollow body 118 open at a top end and closed at a bottom end, wherein an inner surface of the hollow body 118 may include an internal structure configured to hold the case body within the hollow body 118.
[00041] Turning to FIGs. 3 and 4, FIG. 3 illustrates a schematic representation of an insertion process of the case into a case mounting unit of the rib assembly, in accordance with an aspect of the present invention; FIG. 4 illustrates a schematic representation of an assembly overview of the rib assembly, in accordance with an aspect of the present invention. In operation, the case 102 is inserted into the case mounting unit 112 by sliding the tongue 110 of the rib structure on the flat surface 116 and subsequently inserting the beam 108 into the slot 114 of the snap fit locking unit to fit the case 102 inside the case mounting unit 112. The rib structure assembles in a tight fitment way to eliminate the rattling when the case mounting unit 112 is placed in any device having movement. In one exemplary embodiment, the said device may correspond to a portable device having movement, due to which the rattling may be generated within the device, wherein the snap fit locking unit and the rib structure are configured to eliminate the said rattling within the device.
[00042] FIG. 5A to 5D illustrate exemplary schematic representations depicting the details and dimensions of the rib provision, in accordance with an aspect of the present invention. Indication ‘X’ represents the clearance between the case mounting unit 112 and the case 102. Also, the indicator ‘Y’ represents the width of the rib structure 110, and indicator ‘Z’ represents the length of the rib structure 110.
[00043] Furthermore, the exemplary dimension co-relations of the indicators are represented in FIGs. 5A-5D are represented below:
Only if: X = 0.5mm, then Y = 4.5X, and Z = 30Y
[00044] FIG. 6 illustrates a graphical representation of enhancement of the rib structure and insertion force, in accordance with an aspect of the present invention. The graph includes displacement along X-axis and insertion force along Y-axis. Initially before insertion of the case 102 inside the case mounting unit 112, rib 110 will have zero insertion force. Further, as the case 102 is inserted into the case mounting unit 112, the insertion force on the rib 110 and the internal flat surface 116 increases exponentially with the insertion and displacement of the case 102 with respect to the case mounting unit 112 as represented in the graph of FIG. 6.
[00045] While some embodiments of the present disclosure have been illustrated and described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
