Description

BACKGROUND

The present disclosure relates generally to information handling systems, and more particularly to a method and apparatus for coupling a component to an information handling system chassis.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Many information handling systems include components such as, for example, fans, which are coupled to the information handling system chassis. As the information handling system chassis is made smaller and/or more components are added to the information handling system chassis, the space in the information handling system chassis becomes limited, which raises an issue with regards to the coupling of these components to the information handling system.
Typical solutions for coupling components to a chassis include providing spaced apart guide rails mounted to the chassis. The component is then coupled to the chassis by positioning it between the guide rails. However, conventional guide rail solutions require a relatively large amount of space in the information handling system chassis, resulting in less space available for components.
Accordingly, it would be desirable to provide a method and apparatus for coupling a component to a chassis absent the disadvantages found in the prior methods discussed above.

SUMMARY

According to one embodiment, a component coupling apparatus is provided which includes a wall comprising a first surface, a second surface located opposite the first surface, and defining a guide coupling aperture extending through the wall from the first surface to the second surface, a first guide member coupled to the wall through the guide coupling aperture and positioned adjacent the first surface, and a second guide member coupled to the wall through the guide coupling aperture and positioned adjacent the second surface.

Referring now to FIGS. 2, 4 a, 4 b, 6 a, 6 b, 6 c, and 6 d, a method 600 for coupling a component to a chassis is illustrated. The method 600 begins at step 602 where the wall 400, described above with reference to FIGS. 4 a and 4 b, is provided. The method 600 then proceeds to step 604 where a plurality of the guide members 200 are coupled to the wall 400. The guide member 200 is positioned adjacent the wall 400 such that the front surface 202 a of the guide member 200 is adjacent the front surface 402 a of the wall 400 and the coupling members 208 a and 208 b are adjacent the guide coupling apertures 408 b and 408 a, respectively. The coupling members 208 a and 208 b are then extended through the guide coupling apertures 408 b and 408 a, respectively, and secured in the guide coupling apertures 408 b and 408 a, respectively. The tapering of the guide coupling apertures 408 b and 408 a allows the coupling members 208 a and 208 b, respectively, to be secured in the guide coupling apertures 408 b and 408 a, respectively, by moving the guide member 200 such that the coupling members 208 a and 208 b, respectively, enter the narrowed portion of the guide coupling apertures 408 b and 408 a, respectively, as illustrated in FIG. 6 c. The guide member 200 is coupled to the wall 400 in a first orientation A when the securing tab 204 enters the securing aperture 410 b. A guide member 200 may be coupled to the wall 400 through the guide coupling apertures 404 a and 404 b and the securing aperture 406 b in substantially the same manner as described above for the guide coupling apertures 408 a and 408 b and securing aperture 410 b, as illustrated in FIG. 6 c.
Referring now to FIGS. 2, 4 a, 4 b, 6 a, 6 b, 6 c, 6 d, 6 e, and 6 f, the method 600 continues with step 604 by coupling a guide member 200 to the wall 400. The guide member 200 is positioned adjacent the wall 400 such that the front surface 202 a of the guide member 200 is adjacent the rear surface 402 b of the wall 400 and the coupling members 208 a and 208 b are adjacent the guide coupling apertures 408 a and 408 b, respectively. The coupling members 208 a and 208 b are then extended through the guide coupling apertures 408 a and 408 b, respectively, and secured in the guide coupling apertures 408 a and 408 b, respectively. The tapering of the guide coupling apertures 408 a and 408 b allows the coupling members 208 a and 208 b, respectively, to be secured in the guide coupling apertures 408 a and 408 b, respectively, by moving the guide member 200 such that the coupling members 208 a and 208 b, respectively, enter the narrowed portion of the guide coupling apertures 408 a and 408 b, respectively, and are positioned immediately adjacent the coupling members 208 b and 208 a, respectively, on the guide member 200 which is coupled to the front surface 402 a of the wall 400, as illustrated in FIG. 6 f. The guide member 200 is coupled to the wall 400 in a second orientation B when the securing tab 204 enters the securing aperture 410 a, the second orientation B being rotated 180 degrees from the first orientation A such that the top end 202 e on the guide member 200 coupled to the rear surface 402 b of the wall 400 is adjacent the bottom end 202 f of the guide member 200 coupled to the front surface 402 a of the wall 400, as illustrated in FIG. 6 f. A guide member 200 may be coupled to the wall 400 through the guide coupling apertures 404 a and 404 b and the securing aperture 406 a in substantially the same manner as described above for the guide coupling apertures 408 a and 408 b and securing aperture 410 a, as illustrated in FIG. 6 e. With the guide members 200 coupled to the front surface 402 a and the rear surface 402 b of the wall 400, a component coupling apparatus 604 a is provided which includes the wall 400 and the guide members 200 coupled to either side of the wall 400 through the coupling apertures 408 a and 408 b and nested within each other, resulting in a component coupling apparatus 604 a occupying a relatively small amount of space as compared to a conventional component coupling apparatus.
Referring now to FIGS. 3 a, 3 b, 4 a, 4 b, 6 a, 6 g, and 6 h, the method 600 continues with step 604 by coupling the guide feature 300 to the wall 400. The guide feature 400 is positioned adjacent the wall 400 such that the rear surface 302 b of the base 302 and the rear surface 304 bof the mounting arm 304 are adjacent the rear surface 402 b of the wall 400. The guide feature 300 may then be coupled to the wall 400 by positioning the guide surfaces 308 a and 308 b in the guide feature apertures 412 a and 412 b, respectively, positioning the guide surfaces 310 a and 310 b in the guide feature apertures 414 a and 414 b, respectively, and positioning the guide surfaces 312 a and 312 b in the guide feature apertures 416 a and 416 b, respectively, such that the coupling members 314 a and 314 b enter the coupling apertures 418 a and 418 b, respectively. The tapering of the guide coupling apertures 418 a and 418 b allows the coupling members 314 a and 314 b, respectively, to be secured in the guide coupling apertures 418 a and 418 b, respectively, by moving the guide feature 300 such that the coupling members 314 a and 314 b, respectively, enter the narrowed portion of the guide coupling apertures 418 a and 418 b, respectively, as illustrated in FIG. 6 h. The guide feature 300 is coupled to the wall 400 when the securing tab 306 a is positioned in the securing aperture 420. With the guide feature 300 coupled to the wall 400, the guide surfaces 308 a, 308 b, 310 a, 310 b, 312 a, and 312 b extend out past the front surface 402 a of the wall 400. In an embodiment, the guide feature 300 may be removed from the wall 400 by using the beam handle 306 b to deflect the wall securing beam 306 and remove the securing tab 306 from the securing aperture 400.
Referring now to FIGS. 5, 6 a, 6 g, 6 h, and 6 i, the method 600 proceeds to step 606 where the wall 400 is coupled to the a chassis. A chassis 606 a is provided and the wall 400 is positioned in and coupled to the chassis 606 a by, for example, securing the chassis mounting tabs 422 to the chassis 606 a. Another wall 400 is then positioned substantially parallel to and spaced part from the first wall 400 and coupled to the chassis 606 a by, for example, securing the chassis mounting tabs 422 to the chassis 606 a, as illustrated in FIG. 6 i. In an embodiment, additional walls 400 may be coupled to the chassis 606 a. The coupling of the walls 400 to the chassis 606 a defines a component slot C between the guide member 200 coupled to the rear surface 402 b of the wall 400, the guide surface 304 e on the guide feature 300 coupled to the rear surface 402 b of the wall 400, the guide member 200 coupled to the front surface 402 a of the wall 400, and the guide surfaces 308 b, 310 b, and 312 b on the guide feature 300 coupled to the front surface 402 a of the wall 400. The coupling of the walls 400 to the chassis 606 a defines a component slot D between the guide member 200 coupled to the rear surface 402 b of the wall 400, the guide surface 304 d on the guide feature 300 coupled to the rear surface 402 b of the wall 400, the guide member 200 coupled to the front surface 402 a of the wall 400, and the guide surfaces 308 a, 310 a, and 312 a on the guide feature 300 coupled to the front surface 402 a of the wall 400. The coupling of the walls 400 to the chassis 606 a defines a component slot E between the guide member 200 coupled to the rear surface 402 b of the wall 400, the guide surface 304 e on the guide feature 300 coupled to the rear surface 402 b of the wall 400, and various guide features (not shown) similar to those described above.
Referring now to FIGS. 5, 6 a, 6 g, 6 h, 6 i, 6 j, 6 k, 6 l, 6 m, and 6 n, the method 600 proceeds to step 608 where a first component is coupled to the chassis 606 a. A component such as, for example, the fan module 500 described above with reference to FIG. 5, is positioned above the chassis 606 a such that the bottom surface 502 b of the fan module 500 is adjacent the component slot C defined between the walls 400, as illustrated in FIG. 6 j. The fan module 500 is then moved in a direction F such that the fan module 500 enters the component slot C with the side surface 502 c positioned between the guide surface 202 c on guide member 200 and the guide surface 304 e on guide feature 300, as illustrated in FIG. 6 k, and the side surface 502 d positioned between the guide surface 202 d on guide member 200 and the guide surfaces 308 b, 310 b, and 312 b on guide feature 300, as illustrated in FIG. 6 l. Continued movement of the fan module 500 in direction F results in the coupling of the fan module 500 to the chassis 606 ain component slot C, as illustrated in FIG. 6 m. A plurality of additional components such as, for example, the fan modules 500, may be coupled to the chassis 606 a and positioned in the components slots D and E in the same manner as the fan module 500 was positioned to in the component slot C, as illustrated in FIG. 6 n. Thus, a method and apparatus are provided which allow the coupling of components to a chassis while taking up relatively less space in the chassis as compared to a conventional component coupling apparatus.
