Folding wireless communication devices incorporate a two-part housing, which includes a first part that is rotatably coupled to a second part. The overall depth of the device is reduced by adjusting the mechanical layout and component placement relative to one another, wherein previously stacked components have been reordered. More specifically, the hinge, the battery, and the communication and control circuitry have been organized so as to be in the same horizontal plane, and so as to not overlap in a vertical direction.
The present invention relates in general to handheld communication devices. More particularly, the present invention relates to the mechanical layout and component placement for thin handheld communication devices, which have at least a two part housing, where the first housing part is adapted to rotate relative to the second housing part.
Concurrently there is a trend toward increasing the functionality of devices. In the case of cellular telephones, increased functionality includes providing operability on multiple frequency bands using multiple protocols and providing the ability to take and playback photographs and/or video clips. Adding more functionality often leads to increased components and/or circuit elements, which often correspond to increased space requirements, which is at odds with the desire to make devices smaller. Thus, generally, the volume available for accommodating components is at a premium.
Depending upon the overall design and usage goals the reduction of some dimensions may be more desirable than the reduction of other dimensions. For example, while smaller is generally thought to be better in connection with overall size, size reduction can be limited by usage requirements, where if certain components of a device, such as the keypad, are allowed to shrink too much, the device may become difficult to operate. In other instances, there may be a desire to support ever larger components, such as in the case of display screens. Consequently, it becomes a balancing act of competing tradeoffs, when the components are placed relative to one another.
The present inventors have recognized that a further approach, which can be used to adjust dimensioning in a particular direction, can involve the rearrangement of one or more of the components. Rearranging one or more of the components may allow some of the components to be shifted relative to other components, with the potential overall effect of achieving an aggregate dimension in one or more directions, such as depth, which meets the desired results.
FIG. 4 is a cross sectional side view of the handheld device illustrated in FIGS. 1-3;
FIG. 5 is a block diagram of an exemplary mechanical layout and component placement in the prior art;
FIG. 6 is a block diagram of a mechanical layout and component placement, in accordance with at least one embodiment of the present invention;
FIG. 7 is a block diagram of the handheld communication device shown in FIGS. 1-4.
FIG. 1 is a first perspective view of a first handheld communication device, in particular a clamshell wireless communication device 100, shown in a first configuration and FIG. 2 is a second perspective view of the first handheld communication device 100, shown in a second configuration. The device 100 comprises an upper part also know as a flip 102, and a lower part 104. The flip 102 and the lower part 104 are coupled by a rotational coupling, in particular a hinge 106. The device 100 is relatively flat, which is to say that its depth D dimension is smaller than its width W and length L dimensions. In fact, relative to the illustrated embodiment, a reduced depth is an overall design goal. An axis 108 of the hinge 106 is aligned with the width dimension of the device 100. The flip 102 comprise a first inside surface 110, and a first outside surface 202. The lower part 104 comprises a second inside surface 112, and a second outside surface, which is not shown in FIGS. 1 and 2, wherein the second outside surface is facing away from the viewer. The hinge 106 allows the flip 102 to be rotated from the first configuration in which the flip 102 extends upward away from the lower part 104, i.e. opened position, to the second configuration in which the flip 102 overlies the lower part 104, i.e. closed position.
In the illustrated embodiment, the flip 102 comprises a plurality of buttons including a first button 302 (FIG. 3), a second button 304 (FIG. 3), a third button 306 (FIG. 3), and a fourth button 308 (FIG. 3). These buttons 302-308 are not directly visible in FIGS. 1-2. The first through third buttons 302-306 are located proximate a first side edge 116 of the flip 102. The fourth button 308 is located proximate a second side edge 118 of the flip 102. The four buttons 302-308 are covered by three button covers including a first button cover 120, a second button cover 122 and a third button cover 310. The first button 302 and the second button 304 share the first button cover 120, the third button 306 is covered by the second button cover 122, and the fourth button 308 is covered by the third button cover 310. The four buttons 302-308 are used to generate signals for controlling various aspects of the operation of the device 100. In one or more modes of operation of the device 100 the first button 302 and the second button 304 are used as directional inputs, such as “UP” and “DOWN” commands to control software of the device 100. A keypad 124 is located on the inside surface of the lower part 112.
As shown in FIG. 3, the lower part 104 of the device 100 comprises a lower part inner housing part 330 and a lower part outer housing part 332 which are coupled together by screws (not shown) and a pair of resilient catches 334 that are integrally molded with the lower part outer housing part 332. Similar to the upper part, one skilled in the art will recognize other elements and/or methods could be used to hold the lower part inner housing part 330 to the lower part outer housing part 332. A battery compartment 336 is defined between the lower part inner housing part 330, and a battery compartment cover 338 that is located adjacent the lower outer housing part 332. The battery compartment 336 is located proximate a top end 340 of the lower part 104. A battery 342 is substantially disposed in the battery compartment 336. An antenna 344 is located proximate a bottom end 346 of the lower part 104. A populated printed circuit board 348 that includes communication and control circuits of the device 100 is located between the bottom end 346 and the battery compartment 336. The lower part 104 further includes a transducer 353, which is adapted for providing vibrational feedback to the user.
Note that the battery 342 and the populated printed circuit board 348 are located in a common plane 362 (FIG. 4) in a lengthwise L direction, and do not overlap in the direction of depth D. The latter arrangement allows the thickness of the lower part 104 to be reduced, as a result of fewer components being stacked, which reduces the thickness of the entire device 100, making the device 100 more convenient to carry. Note however that this arrangement also limits the longitudinal size of the battery. In the interest of extending battery capacity and thereby the duration of standby time and the amount of communication that can be conducted with the device 100 before battery recharging is necessary, the width of the battery 342 is increased. Placement of the four buttons 302-308 in the flip 102, as opposed to near the top end 340 of the lower part 104 where they would be positioned according to conventional practice, avoids adding to the width of the device 100, which in the illustrated embodiment corresponds to the width of the battery 342, thereby allowing the device 100 to be smaller and making the device 100 more convenient to carry. Positioning the buttons 302-308 in the flip 102 also leads to users tending to position their hands closer to the flip 102 and or the upper part in order to more easily actuate the buttons 302-308. In this position a user's hand will be positioned further away from the antenna 344 located near the bottom end 346 of the lower part 104, and will absorb less energy from signals emanating from, or being received by the antenna 344 thereby leading to improved Quality of Service (QoS). Also, as shown in FIG. 3, the keypad 124 comprises a cover 349 made of a sheet of flexible material. A microphone 350 is mounted on the populated printed circuit board 348 near the bottom end 346 of the lower part 104.
FIG. 4 is a cross-sectional side view of the hand-held device illustrated in FIGS. 1-3, in a closed position. The cross-sectional side view further illustrates the battery 342 in the same horizontal plane as the printed circuit board 348, containing the communication and control circuitry, and the hinge 106. This is a departure from prior systems which largely vertically stacked the printed circuit board 348, as shown in FIG. 5, with the battery 342. FIG. 4 further highlights an antenna 344, which is located near the bottom end 346 of the lower part 104, and which is located in an enclosure further including a polyphonic speaker 321. By placing the antenna 344 proximate the bottom end 346 of the lower part 104, the hinge 106 can similarly be located in the same plane 362 as the battery 342 and the printed circuit board 348. As illustrated in FIG. 5, an antenna 345 alternatively located proximate the top end of the lower part 104, could potentially preclude the placement of a hinge 107 in the same plane 362 as the battery 342 and/or the printed circuit board 348.
FIG. 5 is a block diagram 370 of an exemplary mechanical layout and component placement in the prior art. As noted above, the exemplary prior art mechanical layouts generally included a printed circuit board 348, which was vertically stacked relative to the battery 342. The block diagram 370 further illustrates the general spatial relationship of a keypad 124, display assembly 316, hinge 107 and antenna 345. The dashed line 372 represents a common separation point between items located in the upper part or flip 102, and the lower part 104 of the handheld communication device 100.
FIG. 6 is a block diagram of a mechanical layout and component placement, in accordance with at least one embodiment of the present invention, where consistent with the cross sectional side view illustrated in FIG. 4 illustrates the hinge 106, battery 342 and printed circuit board 348, which includes communication and control circuitry, that is located in the same horizontal plane 362. The vertical dashed lines 382, serve to highlight a component placement, where the corresponding elements, which are located in the same horizontal plane 362, do not vertically overlap. In this way the overall depth of the device can be reduced, in so far as the depth of the printed circuit board does not need to be added to the stack up including the battery 342, keypad 124, and display assembly 316.
FIG. 7 is a block diagram of the handheld communication device 100 shown in FIGS. 1-4. As shown in FIG. 7 the device 100 comprises a transceiver 402, a processor 404, an analog-to-digital converter (A/D) 406, the flip position sensor 352, a camera interface 408, a digital-to-analog converter (D/A) 410, a display driver 412, a button interface decoder 414, a program memory 416, and a workspace memory 418 coupled together through a system bus 420.
The button input decoder 414 is coupled to the one or more buttons 301, which in the embodiment illustrated in FIGS. 1-3 includes the first through forth buttons 302-308 located in the flip 102, as well as to the keys of keypad 124. The button input decoder 414 receives the electrically encoded actuation signals from the keypad 124 and the one or more buttons 301 and identifies each depressed key or button to the processor 404.
The display driver 412 drives the main display 114 and the auxiliary display 204. The D/A 410 drives the earpiece speaker 320 through a second amplifier 424. A similar or the same circuit could also be used to drive the polyphonic speaker 321, shown in FIG. 4.
