[0079] In one embodiment, the power transmitting coil (222) may change in size in response to deformation of the mounting portion (221). The size of the power transmitting coil (222) may include an inner diameter or an outer diameter. For example, the number of turns of the power transmitting coil (222) may change around a central axis (e.g., the z-axis) in response to deformation of the mounting portion (221).

[0081] FIG. 5 is a drawing for explaining a configuration in which a mounting portion (221) of an electronic device (220) is deformed based on a wearable electronic device (210) being placed on an electronic device (220) according to one embodiment of the present disclosure.
[0082] FIG. 5 according to various embodiments is a top view of an electronic device (220) and / or a wearable electronic device (210). FIG. 5 according to various embodiments <510> is a drawing showing a state before the placement of the wearable electronic device (210) on the mounting portion (221) of the electronic device (220) is detected. FIG. 5 <550> This is a drawing showing a state in which the placement of a wearable electronic device (210) is detected on a mounting portion (221) of an electronic device (220).
[0083] Fig. 5 <510> Referring to FIG. 5, the mounting portion (221) of the electronic device (220) may be formed to protrude in a first direction (e.g., in the z-axis direction of FIG. 2) from one side of the housing of the electronic device (220) (e.g., one side (220A) of the housing (2201) of FIGS. 2 and 3). According to one embodiment, FIG. 5 <510> In , the inner diameter of the mounting portion (221) of the electronic device (220) may have a first length (515).
[0084] In one embodiment, the wearable electronic device (210) is shown in FIG. 5. <550> As illustrated, the electronic device (220) can be placed (or positioned, seated) on the mounting portion (221). For example, the mounting portion (221) formed to protrude in a first direction (e.g., z-axis direction) from one side (220A) of the housing (2201) of the electronic device (220) is inserted into the opening (e.g., the opening (215) of FIG. 2) of the wearable electronic device (210), whereby the wearable electronic device (210) can be placed (or positioned, seated) on the mounting portion (221) of the electronic device (220).
[0085] In one embodiment, the inner diameter of the wearable electronic device (210) placed on the mounting portion (221) may be larger than the inner diameter of the mounting portion (221) (e.g., the inner diameter having the first length (515)).
[0086] In one embodiment, the electronic device (220) can determine whether the coil (212) of the wearable electronic device (210) and the power transmission coil (222) of the electronic device (220) are spaced apart from each other when the wearable electronic device (210) is placed on the mounting portion (221) of the electronic device (220). For example, if the intensity of the power transmitted through the power transmission coil (222) is determined to be less than a specified intensity, the electronic device (220) can determine (e.g., determine) that the coil (212) of the wearable electronic device (210) and the power transmission coil (222) of the electronic device (220) are spaced apart from each other. However, the present invention is not limited thereto. When the coil (212) of the wearable electronic device (210) and the power transmission coil (222) of the electronic device (220) are confirmed to be spaced apart, the mounting portion (220) can be elastically deformed to correspond to the inner circumference of the wearable electronic device (210).
[0087] In one embodiment, the mounting portion (221) may include an elastic material. The mounting portion (221) may be elastically deformed (555) (e.g., expanded) to correspond to the inner circumference of the wearable electronic device (210) based on the placement of the wearable electronic device (210) on the mounting portion (221). For example, the mounting portion (221) may be elastically deformed (555) so that no gap occurs between the coil (212) of the wearable electronic device (210) and the power transmission coil (222) of the electronic device (220). For example, the absence of a gap between the coil (212) of the wearable electronic device (210) and the power transmission coil (222) of the electronic device (220) may mean a state (e.g., a state of contact) in which no gap occurs between the inner surface of the wearable electronic device (210) and the outer surface of the mounting portion (221) of the electronic device (210).
[0088] In one embodiment, for example, the mounting portion (221) may be elastically deformed (555) to correspond to the inner circumference of the wearable electronic device (210) through changes in a fluid, such as air, in the inner space of the mounting portion (221). However, the mounting portion (221) may also be elastically deformed (555) to correspond to changes in the size of a power transmitting coil (222) disposed in the inner space of the mounting portion (221).
[0089] In one embodiment, based on the fact that the mounting portion (221) of the electronic device (220) is elastically deformed (555) to correspond to the inner circumference of the wearable electronic device (210), the inner diameter of the mounting portion (221) may have a second length (560) that is longer than the first length (515).

[0091] FIG. 6 according to various embodiments <610> is a drawing showing a power transmitting coil (222) before the placement of a wearable electronic device (210) on a mounting portion (221) of an electronic device (220) is detected. FIG. 6 <650> This is a drawing showing a power transmission coil (222) in a state where the placement of a wearable electronic device (210) is detected on a mounting portion (221) of an electronic device (220).
[0092] Referring to FIG. 6, an electronic device (e.g., an electronic device (220) of FIGS. 2 and 3) may include a power transmitting coil (222) disposed in an internal space of a mounting portion (e.g., a mounting portion (221) of FIGS. 2 and 3). When it is detected that a wearable electronic device (210) is disposed on the electronic device (220), the electronic device (220) may transmit power to the wearable electronic device (210) through the power transmitting coil (222).
[0093] Fig. 6 <610> Referring to FIG. 6, the power transmission coil (222) may be wound multiple times clockwise and / or counterclockwise around the central axis (e.g., z-axis) of the mounting portion (221). <610> In , the inner diameter of the power transmitting coil (222) may have a first length (620).
[0094] In one embodiment, the wearable electronic device (210) may be placed (or positioned, placed) on the mounting portion (221) of the electronic device (220). The inner diameter of the wearable electronic device (210) placed on the mounting portion (221) may be larger than the inner diameter of the mounting portion (221). In this case, as shown in FIG. 5, the mounting portion (221) may be elastically deformed (555) to correspond to the inner circumference of the wearable electronic device (210). The power transmitting coil (222) may also be placed on the mounting portion (221) of FIG. 6. <650> As shown in , the size can be changed in response to the deformation of the mounting portion (221). For example, the number of turns of the power transmitting coil (222) can be changed around the central axis (e.g., z-axis) of the mounting portion (221) in response to the deformation of the mounting portion (221). For example, in FIG. 6 <610> The number of turns of the power transmission coil (222) shown in Fig. 6 <650> The number of turns of the power transmitting coil (222) shown in FIG.
[0095] In one embodiment, the size of the power transmitting coil (222), for example, the inner diameter (or outer diameter), may be changed based on the number of turns changing around the central axis (e.g., the z-axis) of the mounting portion (221). For example, based on the number of turns changing around the central axis (e.g., the z-axis) of the mounting portion (221), the inner diameter of the power transmitting coil (222) may have a second length (655) that is longer than the first length (620).
[0096] In one embodiment, the electronic device (220) may include a capacitor (625) for compensating for inductance due to a change in the size of the power transmitting coil (222). The capacitor (625) may be arranged at a specified interval on one side of the power transmitting coil (222). In one embodiment, as the mounting portion (221) is elastically deformed (555), the inner diameter of the power transmitting coil (222) may change (e.g., change from a first length (620) to a second length (655)), and the electronic device (220) may compensate for the inductance due to the change in the size of the power transmitting coil (222) using the capacitor (625). In one embodiment, the inductance of the power transmitting coil (222) that changes as the inner diameter of the power transmitting coil (222) changes may be determined based on a capacitor-bank composed of the capacitor (625). It is not limited thereto, and the inductance of the power transmission coil (222) that changes as the inner diameter of the power transmission coil (222) changes may be determined to correspond to the changed frequency.
[0097] In one embodiment, the capacitance determined according to the value of the inductance of the power transmitting coil (222) can be calculated based on the following <Mathematical Formula 1>
[0098]
[0099] In one embodiment, the value of the capacitor that changes according to the change in inductance using the above <Mathematical Formula 1> can be calculated based on the following <Mathematical Formula 2>.
