Description

Technical Field

[0001] The present disclosure relates to an expandable component and finds particular (but not exclusive) utility in charging devices for electronic sports equipment such as smart golf clubs. Background Art

[0002] In the sports based on clubs, bats or rackets, one of the most important factors affecting the performance of athletes is the grip of athletes to their clubs, bats or rackets. Slight changes in grip position and strength can have a significant impact on the results of hitting or other sports. For example, in golf, the shot made when there is a slight change in the grip of the golfer (such as a 1 ° change in the angle around the shaft) may cause the position of the ball to change at least one meter after the shot. Golfers and other athletes can change their grip according to the shot results they expect. Usually, athletes understand that changing their grip will change the shape, flight and distance of their shots. Some athletes may aim to use highly consistent grip position and strength, while changing some other aspects of their swing. For right-handed golfers, swinging with so-called strong grip (it is a term used to describe the grip of the left thumb and index finger of the golfer when hitting the ball and their shoulders and / or neck alignment) may cause the ball to travel more to the left than the same swing made with so-called neutral or weak grip. A strong grip is also understood to close the club face and effectively reduce the loft of the club, resulting in the ball flying lower and traveling farther when compared to a shot made with a neutral or weak grip. Thus, a player's grip has a great influence on the outcome of a shot.

[0003] Typically, athletes receive feedback, often including video feedback, about their grip and final shot through training or practice. However, the athlete's grip is not the only factor that affects the outcome of their shot. For example, the swing path of a golf shot and environmental factors such as wind also have a significant impact on the outcome of the shot. Since there are many factors that affect the outcome of a shot, and a small change in the athlete's grip can have a large impact on the outcome of the shot, it is difficult for inexperienced athletes and coaches to correctly diagnose and fix grip errors. In addition, even elite level athletes and coaches may find it difficult to correctly diagnose and fix grip errors.

[0004] Alternatively, the athlete may receive feedback about their grip from a smart device such as a smart golf club. The smart golf club incorporates sensors to measure aspects of the golfer's grip and / or performance such as movement. However, the smart golf club requires a power source to provide power for data collection and data transmission. A charging unit for power may be placed at the bottom of a golf bag to enable the smart golf club to be recharged during a round of golf. However, different golf bags may have different shapes and / or sizes. Therefore, it is desirable to provide a device that may allow the charging unit to fit all types of golf bags. Summary of the invention

[0005] According to a first aspect of the present disclosure, an expandable component of a charging device is provided, the expandable component comprising: an outer boundary, which is configured to be displaced during use; a rotatable member, which is connected to the outer boundary via a connecting member; and a guide portion, which is configured to convert the rotation of the rotatable member into movement of the connecting member, so that the outer boundary moves between a first position and a second position; wherein the outer boundary is arranged to contact an inner wall of a container; and the rotatable member is configured to rotate in response to a rotational input.

[0006] A key advantage of the present disclosure is that the expandable member can provide the charging device with an adjustable system that allows the charging device to be integrated with any container by physically changing the size of the expandable member to match the size of the container.

[0007] The container may be a golf bag. The expandable member may be placed in a bottom or lower portion of the golf bag. The charging device may be configured to charge an object such as a smart golf club. The charging device may be attached or attached to a top surface of the expandable member.

[0008] Alternatively, the expandable member may cooperate or operate with another type of sports bag or equipment bag. The object may be another piece of sports equipment, such as a baseball bat, a tennis racket, a badminton racket, a cricket bat, a hockey stick, a hurling stick, a lacrosse stick, a table tennis racket, a fishing rod, or any other known sports equipment with smart functionality. Thus, the user may charge the smart equipment throughout an event or over a period of time.

[0009] Preferably, the rotatable member is substantially circular, has a curved portion, and includes a grip portion.Therefore, a user can easily apply a rotational force to the rotatable member.

[0010] Preferably, the gripping portion is a dimple. The gripping portion may include a plurality of alternating dimples and teeth placed around the circumference of the rotatable member. Thus, the rotatable member may be a gear. Advantageously, the gear may be easily rotated. Furthermore, the gear may be easily manufactured.

[0011] Preferably, the guide portion comprises: a guide located on the rotatable member; and a ridge adjacent to the connecting member; wherein the ridge is arranged to communicate with the guide. The ridge may be substantially cylindrical in shape, having a ridge width and a ridge height. Alternatively, the ridge may be any suitable shape for communicating with the guide, such as a cone.

[0012] Preferably, the guide extends from a first radial position of the rotatable member to a second radial position of the rotatable member. Further preferably, the second radial position has a greater radial displacement relative to the center of the rotatable member than the first radial position. In this way, the guide allows the ridge to move between the first radial position and the second radial position, thereby allowing the ridge to move radially outwardly relative to the center of the rotatable member. Advantageously, the ridge in turn allows the outer boundary to move radially outwardly via the connecting member in a fixed, secure and adjustable manner.

[0013] Preferably, the guide is an indentation. In this way, the ridge can extend from the first side of the rotatable member through the indentation to the second side of the rotatable member. Advantageously, with this arrangement, the expandable member can occupy less space and can be more robust. Preferably, the indentation has an indentation curvature. In this way, the indentation can convert a rotational force applied to the rotatable member into a force on the ridge, thereby causing the ridge to move radially outward in a smooth manner in response to the force.

[0014] Preferably, the outer boundary is a rigid rod. Advantageously, the rigid rod can allow the expandable member to be rigid in construction and use. Preferably, the rod comprises a rod having a curvature that substantially matches the curvature of the rotatable member. In this way, the rod can maximally contact the inner wall of the substantially cylindrical container. Alternatively, the rod can be of any shape.

[0015] The rod may also include an adhesive portion. The adhesive portion may be adjacent to the outer surface of the rod and configured to contact the container. Advantageously, when the outer boundary extends radially outward and contacts the inner wall of the container, the adhesive portion can reduce the movement of the expandable component in response to external forces, such as during movement of the container, and can assemble the expandable component (for example, with a charging device) in an appropriate position. The adhesive portion can be part of a Velcro fastener, the other part of which is fixed to the inner wall of the container. Alternatively, the adhesive portion can be a magnetic strip that is configured to provide an attractive force together with magnets of opposite polarity within the wall of the container. Alternatively, any suitable adhesive or fixing portion can be used to facilitate attaching the outer boundary to the inner wall of the container.

[0016] In some preferred embodiments, the expandable component further comprises: a sensor located on the exterior of the outer boundary, the sensor being configured to sense the proximity of the outer boundary to an object; a drive member in communication with the rotatable member, the drive member being configured to rotate the rotatable member; and a microcontroller in communication with the sensor and the drive member, the microcontroller being configured to: receive a sensor signal from the sensor; activate the drive member; and deactivate the drive member in response to a contact signal indicating that the outer boundary contacts the object. Advantageously, the operation and sensitivity of the expandable component can be improved. Further advantageously, the expandable component can be automatically expanded using the drive member and can be used more efficiently and easily.

[0017] The sensor may be any one selected from the following range: a proximity sensor; and a pressure sensor. Alternatively, the sensor may be any sensor suitable for sensing the proximity of an object. For example, the sensor may be a Hall effect sensor. The Hall effect sensor may detect a nearby magnetic field originating from, for example, a magnetic strip present in a golf bag.

[0018] Preferably, the microcontroller communicates with a remote computing device configured to send one selected from the following range: an activation signal; and a deactivation signal. The remote computing device may be a smart watch or a smart phone. Alternatively, the remote computing device may be any device suitable for communicating with the microcontroller. In this way, the user may communicate with the expandable member using the remote computing device. Advantageously, the expandable member may be easier to use and does not require specialized equipment.

[0019] In some embodiments, the expandable component further comprises a physical resistance sensor in communication with the drive member, the physical resistance sensor being configured to: measure the physical resistance of the drive member; and send a resistance signal. In this way, the physical resistance of the drive member can be measured, which can indicate that the drive member cannot further expand the expandable component. The drive member may not be able to further expand the expandable component due to the second radial position of the ridge member meeting the guide or the outer boundary contacting the inner wall of the container. Advantageously, the risk of damaging the container can be reduced.

[0020] Preferably, the microcontroller is configured to: activate the drive member in response to an activation signal; and deactivate the drive member in response to a deactivation signal. In this way, a user can control and moderate the expansion of the expandable member.

[0021] Preferably, the outer side of the outer boundary has a first height and the inner side of the outer boundary has a second height, wherein the first height is greater than the second height, so that the outer boundary includes a substantially inclined face. In this way, an object placed above the outer boundary can be biased to move downward along the substantially inclined face towards an area that can contain a charging device. Advantageously, using this feature, the object may be charged.

[0022] Preferably, the expandable component also includes an elastic portion connecting the outer boundary to the rotatable member, the elastic portion being configured to expand when the outer boundary moves from the first position to the second position. Advantageously, an object may be less likely to fall through a gap that may exist in the expandable component. Further advantageously, the elastic portion may be lighter than alternative mechanisms such as an accordion-like mechanism. The elastic portion may also occupy a smaller volume when the expandable component is in a compact state. The elastic portion may be connected to the outer surface of the outer boundary so that the elastic portion includes an inclined surface. Advantageously, an object placed on the elastic portion may be biased to move downward along the substantially inclined surface toward an area that may contain a charging device.

[0023] Preferably, the expandable member further comprises a charging device. The charging device may be attached, abutted or connected to the upper surface of the expandable member in any manner. Preferably, the charging device is placed in a position of maximum contact with the object.

[0024] In some preferred embodiments, the charging device is a charging coil connected to the outer boundary and the rotatable member, the charging coil being configured to move with the outer boundary as the outer boundary moves from the first position to the second position. In this way, the charging device can be easily compacted for transfer and reuse when necessary, while maximizing contact with an object (e.g., a golf club) in the expanded configuration.

[0025] In some preferred embodiments, the expandable component further comprises: a plurality of outer boundaries configured to surround the rotatable member; a plurality of connecting members, each connecting member corresponding to a corresponding outer boundary; and a plurality of guide members, each guiding member corresponding to a corresponding connecting member; wherein, in the first position, the outer boundaries form concentric circles with the rotatable member. Thus, the outer boundaries can maximize contact with the inner wall of the substantially cylindrical container by being a substantially complete circle, the circumference of the circle closely matching the inner wall.

[0026] More than one set of boundaries forming more than one concentric circle can be envisioned.

[0027] In some embodiments, the expandable member further comprises a plurality of charging devices. In this way, the charging surface area can be increased.

[0028] Preferably, at least one of the plurality of charging devices is attached to the corresponding outer boundary, such that: in a first position, the plurality of charging devices are configured to form a stack, wherein the stack is centered on the center of the rotatable member; and in a second position, the outer boundary charging device is displaced from the center of the rotatable member having the corresponding outer boundary. In this way, the charging device can be easily compacted with the expandable member in the first configuration, while also increasing the charging surface area in the second configuration.

[0029] According to a second aspect of the present disclosure, a method for expanding an expandable charging device is provided, comprising the following steps: sending an activation signal to a microcontroller via a remote device; activating a drive member via the microcontroller; driving a ridge along a guide member between a first position and a second position via the drive member so that an outer boundary expands radially outward relative to a rotatable member; receiving a proximity signal from a proximity sensor, the proximity signal indicating that the outer boundary is approaching an object; and receiving a resistance signal from a physical resistance sensor, the physical resistance signal indicating that the ridge has reached the second position; and deactivating the drive member via the microcontroller in response to one selected from the following ranges: the proximity signal satisfies a proximity signal threshold; and the resistance signal reaches a resistance signal threshold, so that the expandable charging device no longer expands.

[0030] According to a third aspect of the present disclosure, a method for contracting an expandable charging device is provided, comprising the following steps: sending a deactivation signal to a microcontroller via a remote device; activating a drive member via the microcontroller; driving a ridge along a guide member between a second position and a first position via the drive member so that the outer boundary contracts radially inward relative to a rotatable member; receiving a resistance signal from a physical resistance sensor, the resistance signal indicating that the ridge has reached the first position; and deactivating the drive member via the microcontroller in response to the resistance signal satisfying a resistance signal threshold.

[0040] FIG. 1a is a top view of an expandable member 100 in a compressed configuration according to a first embodiment of the present disclosure. The device 100 includes a rotatable gear 102 and four extendable members 104. The gear 102 communicates with each of the extendable members 104 via a corresponding guide 106 and a corresponding ridge 108. Although the present embodiment includes four extendable members 104, it should be understood that there are other embodiments in which the expandable member 100 includes a different number of extendable members 104, such as six.

[0041] The gear 102 is substantially circular in shape, such that the gear 102 includes a circumference and a center point. The gear 102 also includes a plurality of periodically repeating indentations and teeth around the circumference, wherein the indentations are configured to accommodate a user's fingers and / or other external members such as a rod.

[0042] The following embodiments are described with respect to a single extendable member and guide engagement structure. Those skilled in the art will appreciate that similar use embodiments are intended to be within the scope of the present application, with additional extendable members and guide engagement structures mirroring the described examples.

[0043] The guide 106 is an indent 106 including a curved portion extending between a first end and a second end of the indent 106. The first end of the indent 106 includes a first radial displacement, and the second end of the indent 106 includes a second radial displacement relative to the center point of the gear 102. The second radial displacement is greater than the first radial displacement, such that the second end of the indent is further away from the center point of the gear 102.

[0044] Referring to FIG. 1 b, a top view of the extendable member 104 of the expandable component 100 is depicted. The extendable member 104 includes a generally rectangular extension rod 110 extending longitudinally along a longitudinal axis. Those skilled in the art will appreciate that the extension rod 110 can be of any suitable shape. Proximate the first end of the extension rod 110, the extendable member 104 includes a boundary rod 112. The boundary rod 112 includes a bend and extends along an axis orthogonal to the longitudinal axis. The inner surface of the boundary rod 112 can be attached to the first end of the extension rod 110 via an adhesive material. Alternatively, the boundary rod 112 and the extension rod 110 can form a single integral molded structure. Alternatively, the boundary rod 112 can be attached to the first end of the extension rod 110 via a fastening member such as a screw.

[0045] The ridge 108 protrudes from the upper surface of the extension rod 110 along an axis that is orthogonal to the longitudinal axis and the axis of the boundary rod 112. The ridge 108 protrudes from the extension rod 110 near a second end opposite the first end of the extension rod 110. The ridge 108 is substantially cylindrical in shape, including a central axis that is orthogonal to the longitudinal axis. Those skilled in the art will appreciate that the ridge 108 can be any suitable shape, such as a cuboid or a cone. The diameter of the substantially cylindrical ridge 108 is less than the width of the guide 106, so that the ridge 108 of the extendable member 104 extends through the corresponding guide 106.

[0046] In the compact configuration shown in Figure la, the ridge 108 extends through the first end of the guide 106, and the extension bar 110 extends radially outward relative to the center point of the gear 102, near the underside of the gear 102. Four curved boundary bars 112 form a complete outer boundary circle.

[0047] In use, and with reference to FIG. 1c , which shows a top view of the device 100 in an expanded configuration, a user may place one or more of their fingers in the indentations located between the teeth of the gear 102. The user applies a first force to the gear 102 by rotating the gear 102 about its axis of rotation, thereby causing the gear 102 to rotate in a direction corresponding to the first force. The first force is then transmitted to the ridge 108 via the guide 106, thereby causing the ridge 108 to move radially outward relative to the center point of the gear 102. The ridge 108, which is attached to the extension rod 110, causes the extendable member 104 to also move radially outward relative to the center point of the gear 102. The ridge 108 continues to move radially outward until the ridge 108 meets the second end of the guide 106, at which point the inner surface of the gear 102 prevents the ridge 108 from moving further outward. Alternatively, the ridge 108 may continue to move radially outward until the outer surface of the boundary rod 112 meets the inner wall of the container, which is a golf bag. The inner wall prevents the ridge 108 from moving further outward.

[0048] When the ridge 108 is close to the second end of the guide 106, the device 100 is in an expanded configuration, as shown in Fig. 1c. In the expanded configuration, the four curved boundary bars 112 are no longer in contact and no longer form a complete outer boundary circle.

[0049] To return the device 100 to the unexpanded configuration, the user can place one or more of their fingers in the indentations located between the teeth of the gear 102. The user applies a second force to the gear 102 by rotating the gear 102 about its rotational axis in a direction opposite to the direction of the first force, thereby rotating the gear 102 in a direction corresponding to the second force. The second force is then transmitted to the ridge 108 via the guide 106, causing the ridge 108 to move radially inward relative to the center point of the gear 102. The ridge 108, which is attached to the extension rod 110, causes the extendable member 104 to also move radially inward relative to the center point of the gear 102. The ridge 108 continues to move radially inward until the ridge 108 meets the first end of the guide 106, at which point the inner surface of the gear 102 prevents the ridge 108 from moving further inward.

[0050] The charging device is placed on the upper surface of the gear 102 .

[0051] The device 100 also includes a hook component of a Velcro attached to an outer surface of the boundary rod 112, the hook component being configured to allow the device to adhere to the golf bag after the outer surface of the boundary rod 112 contacts a loop component of a Velcro attached to an inner wall of the golf bag. Alternatively, the boundary rod 112 may include a magnetic strip configured to attract a magnetic strip included in the inner wall of the golf bag.

[0052] Now turn to Figure 2 , showing a top view of a self-expandable member 200 according to a second embodiment of the present disclosure.

[0053] The automatically expandable member 200 is substantially similar to the expandable member 100 in that the device 200 includes a rotatable gear 202 and four extendable members 204. The gear 202 communicates with each of the extendable members 204 via a respective guide (not shown) and a corresponding ridge (not shown).

[0054] The gear 202 is substantially circular in shape, such that the gear 202 includes a circumference and a center point. The gear 202 also includes a plurality of periodically repeated indentations and teeth around the circumference, wherein the indentations are configured to accommodate a user's fingers and / or other external components. It should be noted that in this embodiment, the indentations and teeth are merely preferred.

[0055] The following embodiments are described with respect to a single extendable member and guide engagement structure. Those skilled in the art will appreciate that similar use embodiments are intended to be within the scope of the present application, with additional extendable members and guide engagement structures mirroring the described examples.

[0056] The guide is a dimple including a curved portion extending between a first end and a second end of the dimple. The first end of the dimple includes a first radial displacement, and the second end of the dimple includes a second radial displacement relative to the center point of the gear 202. The second radial displacement is greater than the first radial displacement, so that the second end of the dimple is further away from the center point of the gear 202.

[0057] The extendable member 204 includes a generally rectangular extension rod 210 extending longitudinally along a longitudinal axis. It will be appreciated by those skilled in the art that the extension rod 210 may be of any suitable shape. Near the first end of the extension rod 210, the extendable member 204 includes a boundary rod 212. The boundary rod 212 includes a bend and extends along an axis orthogonal to the longitudinal axis. The inner surface of the boundary rod 212 may be attached to the first end of the extension rod 210 via an adhesive material. Alternatively, the boundary rod 212 and the extension rod 210 may form a single integral molded structure. Alternatively, the boundary rod 212 may be attached to the first end of the extension rod 210 via a fastening member such as a screw.

[0058] The ridge protrudes from the upper surface of the extension rod 210 along an axis orthogonal to the longitudinal axis and the axis of the boundary rod 212. The ridge protrudes from the extension rod 210 near the second end opposite the first end of the extension rod 210. The ridge is substantially cylindrical in shape, including a central axis orthogonal to the longitudinal axis. Those skilled in the art will appreciate that the ridge can be any suitable shape, such as a cuboid or a cone. The diameter of the substantially cylindrical ridge is less than the width of the guide, so that the ridge of the extendable member 204 extends through the corresponding guide.

[0059] exist Figure 2 In the configuration shown, the ridge extends through the first end of the guide, and the extension bar 210 extends radially outward relative to the center point of the gear 202, near the underside of the gear 202. Four curved boundary bars 212 form a complete outer boundary circle.

[0060] exist Figure 2 In the illustrated embodiment, the automatically expandable member 200 also includes a microcontroller 220 adjacent to the gear 202 and in communication with a smart device 230. The microcontroller can be physically or wirelessly connected to a smart device 230 such as a smart phone or smart watch. For example, the microcontroller 220 and the smart device 230 can communicate wirelessly via WiFi or Bluetooth.

[0061] The automatic expandable member 200 also includes a motor 240 that communicates with the microcontroller 220. The motor 240 is any suitable device capable of converting electrical energy into mechanical energy, such as a stepper motor, and includes a power supply and an ammeter. The motor is operable to rotate the gear 202 in a first direction or a second direction. In this embodiment, the motor 240 is connected to the center point of the lower surface of the gear 202 via a connecting portion 242, so that the rotation of the motor 240 causes the gear 202 to rotate.

[0062] The automatically expandable member 200 also includes a proximity sensor 250 adjacent to the outer surface of the boundary rod 212 in communication with the microcontroller 220. In this embodiment, there is a proximity sensor 250 adjacent to the outer surface of each boundary rod 212. Alternatively, the proximity sensor 250 may be adjacent to the outer surface of a single boundary rod 212 or any number of boundary rods 212. The proximity sensor 250 is any suitable device capable of sensing the proximity of the inner wall of the container, such as a pressure sensor.

[0063] In use and reference Figure 3 , an automatic expansion method 300 is depicted using an automatic expandable component 200 .

[0064] At step 302 of method 300, the automatically expandable member 200 is placed in a container. In this case, the container is a golf bag and the device 200 is placed at the bottom.

[0065] At step 304 , the device 200 is turned on. The device 200 may be turned on via a switch (not shown) or by a user using the smart device 230 .

[0066] At step 306 , the user activates the device 200 by using the smart device 230 .

[0067] At step 308, the smart device 230 sends an activation signal to the microcontroller 220. The activation signal indicates the start of the dilation process.

[0068] At step 310, the pressure sensor 250 begins collecting pressure data and the ammeter begins collecting current data. The pressure sensor 250 continuously sends pressure data to the microcontroller 220, and the ammeter continuously sends current data to the microcontroller 220.

[0069] At step 312, the motor 240 activates the gear 202 via the connection portion 242 and causes the gear to rotate in a first direction. The force is then transmitted to the ridge via the guide, causing the ridge to move radially outward relative to the center point of the gear 202. The ridge attached to the extension rod 210 causes the extendable member 204 to also move radially outward relative to the center point of the gear 202. The ridge continues to move radially outward until the outer surface of the boundary rod 212 meets the inner wall of the golf bag.

[0070] At step 314, the pressure data satisfies the pressure threshold, indicating that the outer surface of the boundary rod 212 has met the inner wall of the golf bag. Alternatively, step 314 may include the current data satisfying the current threshold, indicating that the motor 240 cannot rotate further. The motor 240 may not rotate further because the boundary rod meets the inner wall of the golf bag or the spine meets the second end of the guide.

[0071] At step 316 , the microcontroller sends a deactivation signal to the motor 240 , causing the motor 240 to stop the rotation of the gear 202 .

[0072] After step 318, the device 200 may be shut down.

[0073] In use and reference Figure 4 , an automated compression method 300 is depicted using an automated expandable member 200 .

[0074] At step 402 , the device 200 is turned on. The device 200 may be turned on via a switch (not shown) or by a user using the smart device 230 .

[0075] At step 404 , the user activates the device 200 by using the smart device 230 .

[0076] At step 406, the smart device 230 sends an activation signal to the microcontroller 220. The activation signal indicates the start of the compression process.

[0077] At step 408 , the ammeter begins collecting current data. The ammeter continuously sends the current data to the microcontroller 220 .

[0078] At step 410, the motor 240 activates the gear 202 via the connection portion 242 and causes the gear to rotate in the second direction. The force is then transferred to the ridge via the guide, causing the ridge to move radially inward relative to the center point of the gear 202. The ridge attached to the extension rod 210 causes the extendable member 204 to also move radially inward relative to the center point of the gear 202. The ridge continues to move radially inward until the ridge meets the first end of the guide.

[0079] At step 412 , the current data satisfies the current threshold, indicating that the motor 240 cannot rotate further.

[0080] At step 414 , the microcontroller sends a deactivation signal to the motor 240 , causing the motor 240 to stop the rotation of the gear 202 .

[0081] At step 416, the device 200 may be shut down.

[0082] Figure 5 A side view of an expandable member 500 is shown in accordance with a third embodiment of the present disclosure.

[0083] The expandable member 500 is substantially similar to the expandable member 100 in that the device 500 includes a rotatable gear 502 and four extendable members 504. The gear 502 communicates with each of the extendable members 504 via a respective guide (not shown) and a corresponding ridge (not shown).

[0084] The gear 502 is substantially circular in shape, such that the gear 502 includes a circumference and a center point. The gear 502 also includes a plurality of periodically repeated indentations and teeth around the circumference, wherein the indentations are configured to accommodate a user's fingers and / or other external components. It should be noted that in this embodiment, the indentations and teeth are merely preferred.

[0085] The following embodiments are described with respect to a single extendable member and guide engagement structure. Those skilled in the art will appreciate that similar use embodiments are intended to be within the scope of the present application, with additional extendable members and guide engagement structures mirroring the described examples.

[0086] The guide is an indent including a curved portion extending between a first end and a second end of the indent. The first end of the indent includes a first radial displacement, and the second end of the indent includes a second radial displacement, the radial displacement being relative to a center point of the gear. The second radial displacement is greater than the first radial displacement, such that the second end of the indent is further away from the center point of the gear.

[0087] The extendable member 504 includes a generally rectangular extension rod 510 extending longitudinally along a longitudinal axis. Those skilled in the art will appreciate that the extension rod 510 can be of any suitable shape. Near the first end of the extension rod 510, the extendable member 204 includes a boundary rod 512. The boundary rod 512 includes a bend and extends along an axis orthogonal to the longitudinal axis. The inner surface of the boundary rod 512 can be attached to the first end of the extension rod 510 via an adhesive material. Alternatively, the boundary rod 512 and the extension rod 510 can form a single integral molded structure. Alternatively, the boundary rod 512 can be attached to the first end of the extension rod 510 via a fastening member such as a screw. In addition, the outer edge 512b of the boundary rod 512 has a first height, and the inner edge 512b of the boundary rod 512 has a second height. The second height is lower than the first height. The elastic material 514 is attached to the inner edge 512 at the first end and to the gear 502 at the second end. The elastic material 512 is also attached to the continuous extension rod 510. The elastic material 512 may also be attached to the outer edge of the boundary rod 512 such that the elastic material 512 extends in an inclined surface.

[0088] A ridge (not shown) protrudes from the upper surface of the extension rod 510 along an axis orthogonal to the longitudinal axis and the axis of the boundary rod 512. The ridge protrudes from the extension rod 510 near a second end opposite the first end of the extension rod 510. The ridge is substantially cylindrical in shape, including a central axis orthogonal to the longitudinal axis. Those skilled in the art will appreciate that the ridge can be any suitable shape, such as a cuboid or a cone. The diameter of the substantially cylindrical ridge is less than the width of the guide, so that the ridge of the extendable member 504 extends through the corresponding guide.

[0089] Similar to device 200 , device 500 may also include a microcontroller, a motor, and a proximity sensor.

[0090] In use, the device 500 can be operated using the method 300, or the user can place one or more of their fingers in the indentations located between the teeth of the gear 502. The user applies a first force to the gear 502 by rotating the gear 502 about its axis of rotation, thereby rotating the gear 502 in a direction corresponding to the first force. The first force is then transmitted to the ridge via the guide, causing the ridge to move radially outward relative to the center point of the gear 502. The ridge attached to the extension rod 510 causes the extendable member 504 to also move radially outward relative to the center point of the gear 502. As the extendable member 504 moves radially outward, the elastic material 514 is stretched so that the surface area of ​​the elastic material increases and there is no gap between the gear 502 and the boundary rod 512. The ridge continues to move radially outward until the ridge meets the second end of the guide, at which point the inner surface of the gear 502 prevents the ridge from moving further outward. Alternatively, the vertebrae can continue to move radially outward until the outer surface of the boundary rod 512 meets the inner wall of the container, which is a golf bag. The inner wall prevents the vertebrae from moving further outward.

[0091] Turning now to FIG. 6 a , a top view of an expandable charging device 600 in an expanded configuration is shown according to a fourth embodiment of the present disclosure.

[0092] The expandable charging device 600 is substantially similar to the expandable member 100 in that the device 600 includes a rotatable gear 602 and four extendable members 604. The gear 602 communicates with each of the extendable members 604 via a respective guide 606 and a corresponding ridge.

[0093] The gear 602 is substantially circular in shape, such that the gear 602 includes a circumference and a center point. The gear 602 also includes a plurality of periodically repeated indentations and teeth around the circumference, wherein the indentations are configured to accommodate a user's fingers and / or other external components. It should be noted that in this embodiment, the indentations and teeth are merely preferred.

[0094] The following embodiments are described with respect to a single extendable member and guide engagement structure. Those skilled in the art will appreciate that similar use embodiments are intended to be within the scope of the present application, with additional extendable members and guide engagement structures mirroring the described examples.

[0095] The guide 606 is an indent 606 including a curved portion extending between a first end and a second end of the indent 606. The first end of the indent includes a first radial displacement, and the second end of the indent 606 includes a second radial displacement relative to the center point of the gear 602. The second radial displacement is greater than the first radial displacement, such that the second end of the indent is further away from the center point of the gear 602.

[0096] The extendable member 604 includes a generally rectangular extension rod 610 extending longitudinally along a longitudinal axis. It will be appreciated by those skilled in the art that the extension rod 610 can be of any suitable shape. Near the first end of the extension rod 610, the extendable member 604 includes a boundary rod 612. The boundary rod 612 includes a bend and extends along an axis orthogonal to the longitudinal axis. The inner surface of the boundary rod 612 can be attached to the first end of the extension rod 610 via an adhesive material. Alternatively, the boundary rod 612 and the extension rod 610 can form a single integral molded structure. Alternatively, the boundary rod 612 can be attached to the first end of the extension rod 610 via a fastening member such as a screw.

[0097] The ridge 608 protrudes from the upper surface of the extension rod 610 along an axis that is orthogonal to the longitudinal axis and the axis of the boundary rod 612. The ridge 608 protrudes from the extension rod 610 near the second end opposite the first end of the extension rod 610. The ridge 608 is substantially cylindrical in shape, including a central axis that is orthogonal to the longitudinal axis. Those skilled in the art will appreciate that the ridge 608 can be any suitable shape, such as a cuboid or a cone. The diameter of the substantially cylindrical ridge 608 is less than the width of the guide 606, so that the ridge 608 of the extendable member 604 extends through the corresponding guide 606.

[0098] In the configuration shown in Figure 6a, the ridge 608 extends through the first end of the guide 606, and the extension rod 610 extends radially outward relative to the center point of the gear 602, near the bottom of the gear 602. Four curved boundary rods 612 form a complete outer boundary circle.

[0099] In the embodiment shown in FIG6a, the self-expandable member 600 also includes four charging coils 620. The charging coils 620 each correspond to a respective extendable member 604 in the following manner: the charging coil 620 is attached to the boundary rod 612 at a first attachment point 622 and to the spine 608 at a second attachment point 624. It should be understood by those skilled in the art that the attachment points 622, 624 are not limited to those depicted in FIG6a. The charging coils 620 are attached at different heights such that when the device 600 is in the compressed configuration shown in FIG6b, the charging coils 620 are stacked on top of each other.

[0100] Similar to device 200 , device 600 may also include a microcontroller, a motor, and a proximity sensor.

[0101] In use, the device 600 can be operated using the method 300, or the user can place one or more of their fingers in the indentations between the teeth of the gear 602. The user applies a first force to the gear 602 by rotating the gear 602 about its axis of rotation, thereby rotating the gear 602 in a direction corresponding to the first force. The first force is then transmitted to the ridge via the guide, causing the ridge to move radially outward relative to the center point of the gear 602. The ridge attached to the extension rod 610 causes the extendable member 604 to also move radially outward relative to the center point of the gear 602. As the extendable member 604 moves radially outward, the charging coil 620 also moves radially outward. The ridge continues to move radially outward until the ridge meets the second end of the guide, at which point the inner surface of the gear 602 prevents the ridge from moving further outward. In this configuration, the charging coil covers a maximum surface area. Alternatively, the ridge can continue to move radially outward until the outer surface of the boundary rod 612 meets the inner wall of the container, which is a golf bag. The inner wall prevents the ridge from further outward movement.
