Abstract
Description
Heat spreading member and electronic device including same
[0001] Embodiments disclosed in this document relate to a member capable of lowering the temperature of an internal component of an electronic device and an electronic device including the same.
[0002] Electronic devices are becoming increasingly miniaturized, while their functions are becoming increasingly diverse. As electronic devices become smaller and slimmer, the electrical components embedded in these devices may be positioned with increasingly narrow or concentrated gaps between them and surrounding structures. This, in turn, can generate high temperatures as they perform various functions. The high temperatures generated within these devices can cause malfunctions, damage the internal electrical components, and even cause discomfort to the user. Therefore, electronic devices may incorporate heat dissipation structures that effectively dissipate the heat generated by these internal electrical components to the surroundings.
[0003] An electronic device according to one embodiment disclosed in the present document includes a housing, a first electronic component disposed in a first area inside the housing, a second electronic component disposed in a second area inside the housing different from the first area, and a heat spreading member disposed in a heat dissipation area formed from the first area to the second area, the heat spreading member including a first portion corresponding to the first area and a second portion corresponding to the second area, and a connecting portion connecting the first portion and the second portion, wherein the heat spreading member may include at least one recess.
[0004] A heat spreading member according to one embodiment disclosed in the present document may include a first portion, a second portion through which heat is spread from the first portion, a connecting portion connecting the first portion and the second portion, and a first recess extending from at least a portion of the first portion past the connecting portion to at least a portion of the second portion.

[0015] FIG. 1 is a diagram illustrating a configuration of an electronic device according to one embodiment. For example, the left drawing of FIG. 1 illustrates the internal structure of the electronic device as viewed from the display direction of the electronic device, the center drawing of FIG. 1 illustrates the internal structure of the electronic device as viewed from the rear side (the side opposite the display) of the electronic device, and the right drawing of FIG. 1 illustrates a cross-section along line AA'.
[0016] According to one embodiment, an electronic device (100) (e.g., electronic device (901) of FIG. 9) may include a heat spreading member (110) within a housing. For example, the housing may include a support structure (120). For example, the support structure (120) may form at least a portion of a side housing of the electronic device (100). The heat spreading member (110) may be disposed within a space within the support structure (120).
[0017] According to one embodiment, the electronic device (100) may include a heat spreading member (110) (e.g., heat spreading member (301, 303, 305) of FIG. 3, heat spreading member (430) of FIG. 4, or heat spreading member (820) of FIG. 8) within a housing, a support structure (120), a shielding member (130), a heat transfer member (140), a memory (150), a processor (160), and / or a substrate (170) (e.g., a circuit board (170)).
[0018] According to one embodiment, the heat spreading member (110) can spread heat generated in a first region (e.g., a first component (e.g., a processor (160))) within the electronic device (100) to a second region different from the first region within the electronic device (100). For example, the heat spreading member (110) can lower the temperature within the electronic device (e.g., the first component) by spreading heat generated from the first component, which generates relatively high temperature heat within the electronic device (100), to another region. For example, the heat spreading member (110) can include a vapor chamber. For example, referring to FIG. 1, the heat spreading member (110) can have a generally uniform width and be arranged along one direction (e.g., vertically or horizontally) of the electronic device. For example, the heat spreading member (110) can spread heat generated from a component arranged in the first region along the longitudinal direction. In one embodiment, the heat spreading member (110) may be secured to the support structure (120) via adhesive tape, or may be secured to the support structure (120) via laser welding.
[0019] In one embodiment, a support structure (120) (e.g., a metal front structure) may secure a heat spreading member (110). In one embodiment, the support structure (120) may be formed of a metal material. In one embodiment, the support structure (120) may be positioned below the heat spreading member (110) to support the heat spreading member (110).
[0020] In one embodiment, the shielding member (130) can reduce or block electromagnetic interference occurring inside the electronic device (100). In one embodiment, the shielding member (130) can be formed of a material such as metal or nanofiber (e.g., nano TIM). In one embodiment, the shielding member (130) can include a conductive shielding film. In one embodiment, the shielding member (130) can be disposed under the support structure (120).
[0021] In one embodiment, a heat transfer member (140) (e.g., a gel TIM member) can transfer heat from inside the electronic device (e.g., a component inside the electronic device) to the heat spreading member (110). In one embodiment, the heat transfer member (140) can be disposed below the shielding member (130). For example, the heat transfer member (140) can be disposed between a first component that is a heat source (e.g., a processor (160)) and the heat spreading member (110).
[0022] According to one embodiment, the memory (150) and the processor (160) may be disposed on the substrate (170). According to one embodiment, the memory (150) may include a universal flash storage (UFS). According to one embodiment, the memory (150) may store data used in the electronic device (100). According to one embodiment, the processor (160) may control the overall operation of the electronic device. For example, the processor (160) may be a heat source that emits heat at a relatively higher temperature than other components within the electronic device (100).
[0023] According to one embodiment, the electronic device may include a battery (not shown). For example, at least a portion of the heat spreading member (110) may be arranged to overlap the battery. For example, the heat spreading member (110) may spread heat generated from a first component (e.g., a processor (160)) toward the battery. For example, the heat spreading member (110) may spread heat emitted from a processor (160) that emits relatively high heat toward a battery that has a relatively low temperature, thereby lowering the temperature of the processor (160), thereby preventing malfunction due to high temperature and damage to internal components of the electronic device (100).
[0024] According to one embodiment, the components and internal arrangement of the electronic device in FIG. 1 are not limited to those illustrated in FIG. 1.
[0025]
[0026] FIG. 2 is a diagram showing the configuration of an electronic device according to one embodiment. Hereinafter, descriptions overlapping with those of FIG. 1 will be omitted or briefly described. According to one embodiment, the components and internal arrangement of the electronic device in FIG. 2 are not limited to those illustrated in FIG. 2. For example, the left drawing of FIG. 2 illustrates the internal structure of the electronic device as viewed from the display direction of the electronic device, the central drawing of FIG. 2 illustrates the internal structure of the electronic device as viewed from the rear side (the side opposite the display) of the electronic device, and the right drawing of FIG. 2 illustrates a cross-section along line BB'.
[0027] According to one embodiment, an electronic device (200) (e.g., electronic device (901) of FIG. 9) may include a heat spreading member (210) (e.g., heat spreading members (301, 303, 305) of FIG. 3, heat spreading member (430) of FIG. 4, or heat spreading member (820) of FIG. 8) within a housing, a support structure (220), a shielding member (230), a heat transfer member (240), an additional heat transfer member (280), a memory (250), a processor (260), and / or a substrate (270).
[0028] Compared to FIG. 1, the electronic device (200) may further include an additional heat transfer member (280). In one embodiment, the support structure (220) or the shielding member (230) may include some openings. In one embodiment, the additional heat transfer member (280) may be disposed between the processor (260) and the heat spreading member (210) so that heat emitted from the processor (260) may be directly transferred to the heat spreading member (210). For example, the additional heat transfer member (280) may include a member formed of a metal material (e.g., a metal block or a copper block). For example, the additional heat transfer member (280) may contact the heat spreading member (210) and the heat transfer member (240), and the heat transfer member (240) may contact the processor (260). Accordingly, heat generated in the processor (260) may be transferred to the heat transfer member (240) and the additional heat transfer member. The heat can be transferred to the heat spreading member (210) through the additional heat transfer member (280). For example, the heat generated in the processor (260) can be more easily transferred to the heat spreading member (210) by the additional heat transfer member (280).
[0029] In one embodiment, the heat spreading member (210) may not be formed with the same width but may include regions with different widths. For example, the heat spreading member (210) may be formed with a narrower width in a region corresponding to a component (e.g., the processor (260)) that emits relatively high temperature heat inside the electronic device (200), and may be formed with a wider width in a region where heat is spread (e.g., a region overlapping with a battery). In one embodiment, when the heat spreading member (210) has a wider width (larger area), the heat spreading performance may be increased, making it more efficient in lowering the temperature of the components inside the electronic device (200). For example, when the heat spreading member (210) has a wider width (larger area), the rigidity of the heat spreading member (210) may be weakened, increasing the possibility of damage such as deformation or weld separation when an external impact is applied. Hereinafter, a structure capable of enhancing the resistance of the heat diffusion member (210) to external impact will be described in more detail in FIG. 3a and below.
[0030]
[0031] FIGS. 3A to 3D are diagrams illustrating the structure of a heat diffusion member of an electronic device according to various embodiments. According to one embodiment, an electronic device (not shown) (e.g., an electronic device (901) of FIG. 9) may include a heat diffusion member (301, 303, 305) (e.g., a heat diffusion member (110) of FIG. 1, a heat diffusion member (210) of FIG. 2, a heat diffusion member (430) of FIG. 4, or a heat diffusion member (820) of FIG. 8).
[0032] According to one embodiment, referring to FIG. 3A, the heat spreading member (301) may include a first portion (310), a second portion (320), and a connecting portion (330) connecting the first portion (310) and the second portion (320). According to one embodiment, the first portion (310) may be positioned on a first electronic component (e.g., a processor) that becomes a heat source that emits relatively high temperature heat inside the electronic device, and the second portion (320) may be positioned on a second electronic component (e.g., a battery) that is spaced apart from the heat source. According to one embodiment, the size (e.g., area) of the first portion (310) may be smaller than the size of the second portion (320). For example, as the size of the first portion (310) or the second portion (320) increases, the heat spreading performance (e.g., heat dissipation performance) of the heat spreading member (301) may increase. For example, the first part (310) may be placed at a position corresponding to a first area where a first electronic component (e.g., a processor) of the electronic device is placed, and the second part (320) may be placed at a position corresponding to a second area where a second electronic component (e.g., a battery) of the electronic device is placed.
[0033] According to one embodiment, the heat spreading member (301) can include at least one recess (and / or slot). For example, the heat spreading member (301) can include a first recess (341) extending from at least a portion of the first portion (310) past the connecting portion (330) to at least a portion of the second portion (320). For example, the first recess (341) can be formed along the longitudinal direction (e.g., longitudinal direction) of the heat spreading member (301). For example, the heat spreading member (301) can be susceptible to longitudinal bending deformation (e.g., longitudinally folded when the heat spreading member (301) has a longitudinal length greater than a transverse length), and the first recess (341) can reduce or prevent longitudinal bending deformation of the heat spreading member (301) by increasing longitudinal bending stiffness. For example, the first recess (341) may be formed along the centerline of the heat spreading member (301) extending from at least a portion of the first portion (310) to at least a portion of the second portion (320).
[0034] According to one embodiment, referring to FIG. 3B, the description overlapping with FIG. 3A is omitted or briefly described below. According to one embodiment, the heat spreading member (303) may include at least one recess (343, 350) (and / or a slot). For example, the heat spreading member (303) may include a first recess (343) formed in the longitudinal direction. For example, the heat spreading member (303) may include at least one second recess (350) formed in a second direction different from the first direction extending from the first part (e.g., the first part (310) of FIG. 3A) to the second part (e.g., the second part (320) of FIG. 3A) in the connecting part (e.g., the connecting part (330) of FIG. 3A) of the heat spreading member (303). For example, the heat spreading member (303) can include at least one second recess (350) in at least one of the first portion, the second portion, and / or the connecting portion. In one embodiment, the at least one second recess (350) can be connected to the first recess (343) at one point. In one embodiment, the at least one second recess (350) can be formed substantially perpendicular to the first recess (343). For example, the second recess (350) can be formed substantially in the short-length direction (e.g., the short-axis direction) of the heat spreading member (303). In one embodiment, the at least one second recess (350) can be formed in at least one of the first portion, the connecting portion, and / or the second portion. For example, the at least one second recess (350) can improve the torsional rigidity of the heat spreading member (303).
[0035] According to one embodiment, referring to FIG. 3C, the description overlapping with FIGS. 3A and 3B is omitted or briefly described below. According to one embodiment, the heat spreading member (305) may include at least one recess (345, 350) (and / or a slot). For example, the heat spreading member (305) may include a first recess (345) formed in the longitudinal direction. For example, the heat spreading member (305) may include at least one third recess (360) formed to have a specified angle with the first recess (345) in a second portion (e.g., the second portion (320) of FIG. 3A). For example, the at least one third recess (360) may include a recess that intersects the first recess (345) at a substantially right angle. For example, at least one third recess (360) can reduce the area of a dome-shaped deformation that may occur in the second portion, and / or reduce the amount of dome-shaped deformation. For example, the first recess (345) and / or the third recess (360) can distribute a dome-shaped deformation that may occur throughout the second region into a plurality of smaller dome-shaped deformations. For example, the first recess (345) and / or the third recess (360) can distribute the amount of impact applied to the second region, thereby reducing the degree to which the second region is deformed.
[0036] Referring to FIG. 3d, the changes in strength and the shapes of natural vibration modes of the heat diffusion members (301, 303, 305) according to the first example (in the case of FIG. 3a), the second example (in the case of FIG. 3b), and the third example (in the case of FIG. 3c) are shown. For example, it can be confirmed that the strength of the heat diffusion members (301, 303, 305) increases significantly in the order of the first example, the second example, and the third example, and the natural vibration modes correspond to the first mode, the second mode, and the third mode, respectively. According to various embodiments, the position, shape, direction, and / or number of each recess can be determined in a direction that can improve the first mode, the second mode, and the third mode, which have a large influence on deformation, among the natural vibration modes of the heat diffusion members (301, 303, 305). For example, improving the bending characteristics of the heat diffusion member (301, 303, 305) in the long longitudinal direction (e.g., major axis direction) of the heat diffusion member (301, 303, 305) may be most effective in increasing the strength of the heat diffusion member (301, 303, 305). For example, if a recess is formed along the long longitudinal direction of the heat diffusion member (301, 303, 305), the effect of increasing the strength through the recess may be relatively the highest.
[0037] According to one embodiment, by forming at least one recess in the heat spreading member (301, 303, 305), the strength of the heat spreading member (301, 303, 305) can be increased and the possibility of deformation and damage of the heat spreading member (301, 303, 305) from external impact (e.g., dropping of the electronic device or collision with an external object) can be reduced.
[0038] According to various embodiments, the shape, position, direction, and / or number of recesses formed in the heat spreading member (301, 303, 305) are not limited to those illustrated in FIGS. 3A to 3C.
[0039]
[0040] FIG. 4 is a drawing for explaining a change in the stiffness of a heat diffusion member of an electronic device according to one embodiment.
[0041] For example, 410 illustrates a first heat diffusion member (410) that does not include a recess (435), and 420 represents the stiffness of the first heat diffusion member (410) against an external impact. 430 illustrates a second heat diffusion member (430) (e.g., the heat diffusion member (301) of FIG. 3A) that includes a recess (435), and 440 represents the stiffness of the second heat diffusion member (430) against an external impact. For example, since the second heat diffusion member (430) disperses the external impact through the recess (435), the external impact amount (445) applied to the second heat diffusion member (430) can be in a smaller range and with a smaller intensity than the external impact amount (425) applied to the first heat diffusion member (410).
[0042] For example, the first heat diffusion member (410) may not include a recess (435) extending in the longitudinal direction at the center. In this case, since the first heat diffusion member (410) has relatively low rigidity (e.g., stiffness), there is a high possibility that deformation and / or damage may occur in response to an impact applied to the first heat diffusion member (410).
[0043] For example, the second heat diffusion member (430) may include a recess (435) extending longitudinally in the center. In this case, the rigidity of the second heat diffusion member (430) may be increased due to the recess (435). For example, when a relatively equal external impact is applied, the second heat diffusion member (430) may be less likely to be deformed and / or the degree of damage may be reduced.
[0044] For example, as illustrated in FIG. 4, when the first heat diffusion member (410) and the second heat diffusion member (430) have the same shape and the same thickness, and an external impact of the same magnitude is applied, the stiffness of the first heat diffusion member (410) and the second heat diffusion member (430) may vary significantly. For example, by forming the recess (435), the stiffness of the second heat diffusion member (430) may increase significantly more than the stiffness of the first heat diffusion member (410), and the resistance to the external impact (e.g., yield stress) may increase significantly.
[0045] According to one embodiment, FIG. 4 only shows a case where the heat diffusion member (e.g., the second heat diffusion member (430)) includes one recess (435) in the longitudinal direction, but if the heat diffusion member includes a recess (435) in each direction, the rigidity of the heat diffusion member against external impact in the corresponding direction can be increased.
[0046]
[0047] FIG. 5 shows the results of simulating the extent of damage due to a drop impact of a heat diffusion member of an electronic device according to one embodiment. For example, FIG. 5 shows the results of performing a half-sine wave stress simulation (using JEDEC H drop conditions) for a drop load of the JEDEC standard in order to check the extent of damage when changing the specifications (e.g., thickness) of a heat diffusion member (hereinafter referred to as a “vapor chamber (VC)”) of the same shape (e.g., a heat diffusion member (110) of FIG. 1, a heat diffusion member (210) of FIG. 2, a heat diffusion member (301, 303, 305) of FIG. 3, a heat diffusion member (430) of FIG. 4, or a heat diffusion member (820) of FIG. 8) or applying a strength-reinforced structure (e.g., a recess).
[0048] For example, when a standard drop simulation is performed from a specified height (e.g., 150 cm) for a first VC with a 0.29T specification, a second VC with a 0.35T specification, and a third VC with a 0.35T specification reinforcement structure, it can be confirmed that the stress decreases in the order of the first VC, the second VC, and the third VC, and the failure criterion (yield) decreases. For example, as shown in the table in Fig. 5, it can be confirmed that the degree of deformation (e.g., the highlighted area) is severe in the order of the first VC, the second VC, and the third VC.
[0049] According to one embodiment, when an electronic device (e.g., a terminal) including a VC (e.g., the electronic device (901) of FIG. 9) is dropped, a shear force (shear load) due to the inertia of the battery may occur, causing plastic deformation around the welding portion of the VC. For example, a load may be transmitted to the contact surface between the VC and the battery, causing a yield stress in the VC and deformation and damage to the joint portion of the VC. In FIG. 6 below, a flange structure for preventing deformation of the VC will be described in more detail.
[0050]
[0051] FIG. 6 is a drawing showing a flange structure of a heat diffusion member according to various embodiments. For example, FIG. 6 shows a structure (hereinafter referred to as a “flange structure”) of a designated edge region of a heat diffusion member (e.g., a heat diffusion member (110) of FIG. 1, a heat diffusion member (210) of FIG. 2, a heat diffusion member (301, 303, 305) of FIG. 3, a heat diffusion member (430) of FIG. 4, or a heat diffusion member (820) of FIG. 8).
[0052] In one embodiment, the first heat spreading member (601) may include a first plate (610) and a second plate (620). In one embodiment, the first plate (610) and the second plate (620) may be joined at an edge of the first heat spreading member (601) to form an outer appearance of the first heat spreading member (601). For example, the flange structure of the first heat spreading member (601) may have a significant effect on the rigidity of the first heat spreading member (601). For example, the first heat spreading member (601) may be secured to a support member within the electronic device by tape or laser welding. When laser welding is used, the flange structure may have a relatively greater effect on the rigidity of the first heat spreading member (601).
[0053] According to one embodiment, the second heat diffusion member (603) represents a case where the thickness of the flange structure is increased compared to the first heat diffusion member (601). For example, the thickness (t2) of the flange structure of the second heat diffusion member (603) may be formed to be relatively thicker than the thickness (t1) of the flange structure of the first heat diffusion member (601). For example, when the thickness of the first plate (610) and / or the second plate (620) forming the flange structure is increased, the rigidity of the second heat diffusion member (603) may be increased. According to one embodiment, the thickness of the first plate (610) and / or the second plate (620) that are joined to each other in a designated area of the edge of the second heat diffusion member (603) may be formed to be thicker than the thickness outside the designated area. According to one embodiment, a third plate (630) having a designated thickness may be joined between the first plate (610) and the second plate (620). For example, by additionally joining the third plate (630), the thickness of the flange structure of the second heat diffusion member (603) can be increased, and an effect that facilitates designing various welding surfaces (welding areas and / or shapes) can be obtained. For example, as the flange structure becomes thicker, the rigidity (e.g., stiffness) of the second heat diffusion member (603) can be increased.
[0054] According to one embodiment, at least one recess (635) (and / or slit) may be formed in the first plate (610) and / or the second plate (620) of the flange structure of the third heat diffusion member (605). For example, when the recess (635) is formed in the flange structure, the second cross-sectional moment may structurally increase due to the recess (635), and the rigidity of the heat diffusion member may increase. For example, the third heat diffusion member (605) is illustrated as having a plurality of recesses (635) formed in the upper portion (the first plate (610)) and the lower portion (the second plate (620)) of the flange structure of the second heat diffusion member (603), but the embodiment of the present invention is not limited thereto. For example, the shape, position, and / or number of the recesses (635) of the flange structure can be changed, and the recesses (635) can be formed in various flange structures including the flange structure of the first heat spreading member (601). For example, the recesses (635) can be formed in either the first plate (610) or the second plate (620), and the size, shape, and / or depth of the recesses (635) can be formed differently. For example, the depth of the recesses (635) can be formed to be equal to or shallower than the thicknesses of the first plate (610) and the second plate (620).
[0055] According to various embodiments, the shape of the flange structure and the form and number of the recesses are not limited to those illustrated in FIG. 6, and the shape of the flange structure, the method of adjusting the thickness, and / or the structure or number of the recesses may be changed.
[0056]
[0057] FIG. 7 is a diagram showing the structure of a heat spreading member according to one embodiment. For example, FIG. 7 illustrates a flange structure of a heat spreading member (e.g., a heat spreading member (110) of FIG. 1, a heat spreading member (210) of FIG. 2, a heat spreading member (301; 303; 305) of FIGS. 3A to 3C, a heat spreading member (430) of FIG. 4, a heat spreading member (601; 603; 605) of FIG. 6, or a heat spreading member (820) of FIG. 8) disposed inside an electronic device (e.g., an electronic device (100) of FIG. 1, an electronic device (200) of FIG. 2, an electronic device (800) of FIG. 8, or an electronic device (901) of FIG. 9) according to one embodiment.
[0058] In one embodiment, an edge (e.g., a flange structure) of a heat spreading member (e.g., a vapor chamfer) may be disposed in an area where a battery (740) (e.g., battery (989) of FIG. 9) is disposed within a housing of the electronic device. For example, a support structure (720) may be disposed on top of the battery (740). For example, the support structure (720) may be bonded to the battery (740) via a bonding tape (730). For example, a display (705) of the electronic device may be disposed on top of the support structure (720). In one embodiment, the support structure (720) may be formed to support and secure the heat spreading member. In one embodiment, the support structure (720) may be bonded to at least a portion of the heat spreading member via a bonding tape (710) or laser welding.
[0059] In one embodiment, the heat spreading member may include a first plate (750) and a second plate (760). For example, the first plate (750) and the second plate (760) may be joined at a designated edge region of the heat spreading member to form a flange structure (e.g., 601; 603; 605 of FIG. 6) of the heat spreading member. In one embodiment, the flange structure of the heat spreading member may be attached to at least a portion of one side of the upper structure and / or one side of the lower structure. For example, the flange structure of the heat spreading member may be attached to at least a portion of one side of an opposite side of the battery (740) (e.g., the display (705)). In another example, the flange structure of the heat spreading member may be attached to at least a portion of one side of the battery (740). For example, a space may be formed between the first plate (750) and the second plate (760) in the central region of the heat diffusion member (outside the above-mentioned region), and a structure for heat diffusion may be formed.
[0060] In one embodiment, the first plate (750) and the second plate (760) may have a thicker thickness in a region other than a designated region at an edge of the heat diffusion member (hereinafter referred to as a “flange structure” of the heat diffusion member). For example, a portion of the plates forming the flange structure of the heat diffusion member may be formed to have a thicker thickness than other portions. For example, a third plate may be bonded between the first plate (750) and the second plate (760) such that the portion forming the flange structure of the heat diffusion member may be formed to have a thicker thickness than other portions. In one embodiment, the flange structure of the heat diffusion member may include at least one recess. For example, due to the flange structure including the recess, the second moment of inertia of the flange structure may be increased, and the rigidity of the heat diffusion member may be increased. For example, a flange structure including a recess can be formed by bonding an additional plate including a recess to the outside of the first plate (750) and / or the second plate (760), thereby increasing the thickness of the flange structure.

For example, a processor (e.g., a processor (920)) of the machine (e.g., an electronic device (901)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.
[0117] According to one embodiment, the method according to various embodiments disclosed in the present document may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) via an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.
[0118] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to various embodiments, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
