[0066] Reference will now be made in detail to example embodiments, examples of which are illustrated in the accompanying drawings. The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps or operations for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.
[0067] According to an example embodiment a system for disassembling a cover of a user device is disclosed. The cover may be a rear cover. The system may comprise the user device, which may comprise the cover, a slot in connection with the receiving space, a movable lifting part located between the cover and the slot having a resting position and a lifting position. The system may also comprise a tool which may comprise a first end, a second end, and a middle part. The tool may be configured to move the lifting part towards the cover from the resting position to the lifting position for disassembling the cover. According to an example embodiment, a SIM card may be located in its place when the cover is opened. Thus, the SIM card need not to be removed. The slot may be located any part of the user device.
[0068] The user device may further comprise a hole, a receiving space inside the user device, and a card holder, which may receive at least one card and may be removably located into the receiving space. The first end of the tool may be pressed into the hole for removing the card holder from the receiving space. The hole may be located in the card holder or in a user device body. After that the tool may be turned. This way the second end of the tool may be located inside the slot and the tool may be rotated in the slot for disassembling the cover.
[0069] The user device (also called UE, user equipment, user terminal, terminal device, etc. ) illustrates one type of an apparatus and thus any feature described herein with a user device may be implemented with a corresponding apparatus.
[0070] The user device refers, for example, to a wireless mobile communication device operating with a Subscriber Identification Module (SIM) , including, but not limited to, the following types of devices: a mobile station (mobile phone) , smartphone, personal digital assistant (PDA) , handset, device using a wireless modem (alarm or measurement device, etc. ) , laptop and / or touch screen computer, tablet, game console, notebook, navigation device, vehicle infotainment system, and multimedia device, or any combination thereof. It should be appreciated that a user device may also be a nearly exclusive uplink only device, of which an example is a camera or video camera loading images or video clips to a network. A user device may also be a device having capability to operate in Internet of Things (IoT) network which is a scenario in which objects are provided with the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. The user device may also utilise cloud. In some applications, a user device may comprise a small portable device with radio parts (such as a watch, earphones or eyeglasses) and the computation is carried out in the cloud. The user device is configured to perform one or more of user equipment functionalities. The user device may also be called a subscriber unit, mobile station, remote terminal, access terminal, user terminal or user equipment (UE) just to mention but a few names or apparatuses.
[0071] A SIM card is also known as a smart card or ID card. It stores user data, authentication algorithms, and keys necessary for identifying the subscriber within a mobile communication system. The user device may require a SIM card to function. Typically, the SIM card may be placed in a designated card holder within the user device. The card holder may be designed to accommodate various types of SIM cards, eliminating the need for users to replace their existing SIM cards to fit different user devices. The card holder may comprise a body having a hole or recess for receiving the SIM card. The hole may also be in the user device body. A tool may be used for ejecting the card holder out of the receiving space.
[0072] Example embodiments relate to a system in which the tool may be used to pop open the card holder using the first end of the tool in a conventional manner. The tool is, for example a two-ended single tool or a SIM pin. The card holder is, for example a SIM or an external memory tray or a combination thereof. The tool may pop open the cover or a lid of the end-user device by inserting the second end of the tool to the slot that is revealed when the card holder is removed, and by turning the tool. The slot may be located behind the card holder, or it may not be located behind the card holder. In some embodiments, it is possible that the slot is located freely in the device surface. The slot is located, for example, on the opposing side or the card holder. The hole may not be in connection with the receiving space. In this embodiment the SIM card may be located in its place when the cover is opened.
[0073] According to an example embodiment, when the tool is turned, the second end, for example a lever, may generate transversal forces in addition to perpendicular forces. If the second end at the end of the tool would contact the cover directly, it may try to push the cover not only up, but also sideways. For design reasons the cover may be made of brittle material, for example glass. The brittle material may crack if scraped with the second end, even in room temperatures. Users may also “pop” the cover unnecessarily multiple times, which may break even more scratch-and crack resistant materials.
[0074] Example embodiments relate to the user device comprising a lifting part located between the cover and the slot. The lifting part is, for example a tab or a bollard. The lifting part may be used to take all scraping forces. When the tool is turned, it may exert forces to the lifting part. Transversal forces caused by the turning tool may be carried for example by a chassis or another internal structure or structures. This means that the transversal forces may not be exerted to the cover. As a result, only perpendicular forces are exerted to the cover. Form of the lifting part may also be wider from a lifting surface at an upper end of the lifting part at the lifting surface. This may cause pressure of the lifting part to be exerted to a wider area of the cover. As a result, it may prevent cracking of the cover.
[0075] According to an example embodiment, the middle part of the tool may also be used to help to lift the cover when the tool may be rotated in the slot. The middle part may have protrusion or phi-like form, which may touch an edge of the cover at the same time when the tool is turned and the second end of the tool lifts the lifting part.
[0076] Examples of figures 1a to 1d show a system comprising a user device 1 and a tool 2 and how the tool 2 is used for disassembling a cover 3 of the user device 1. An example of figure 2 shows details of the tool 2 and figure 3a an exploded view of the system.

A tool 2 may be configured to move M the lifting part 11 towards the cover from the resting position to the lifting position for disassembling the cover 3.
[0079] According to an example embodiment, a first end 8 of the tool may be configured to be pressed into the hole 4 for removing the card holder 5 from the receiving space 6. After that the second end 9 of the tool 2 may be configured to be located inside the slot 7. Finally, the tool 2 may be configured to be rotated in the slot 7 for disassembling the cover 3.
[0080] The system may also comprise a tool 2 for disassembling a cover 3 of a user device 1 as shown in an example of figure 2. The tool may comprise a first end 8, a second end 9, and a middle part 10. The middle part 10 may comprise a protrusion or an uppercase phi form. The second end 9 of the tool 2 may have a bended form, letter J form, or a hook like form. The slot 7 may have a form that corresponds to an outer shape of the second end 9 of the tool 2. The form of the slot 7 may allow the second end 9 of the tool 2 to fit into the slot 7.
[0081] According to an example embodiment of figure 1a, a first end 8 of the tool 2 is configured to be pressed into a hole 4 of a user device 1 according to arrow A for removing a card holder 5 from a receiving space 6 of the user device. The arrow A may show a direction to insert the tool 2 into the hole 4.
[0082] Figure 1b shows an example of the system, wherein the card holder 5 is removed from the receiving space 6 according to arrow B. The arrow B may show a direction to remove the card holder 5 from the receiving space 6. When the first end 8 of the tool 2 is pressed into the hole 4 it may pop out the card holder 5. This may reveal the receiving space 6 of the card holder 5 and the slot 7 in the receiving space 6 or the slot 7 that may be at the end of the receiving space 6.
[0083] According to an example embodiment, after the card holder 5 is removed from the receiving space 6, the tool 2 may be turned around according to arrow F along its longitudinal axis X before the second end 9 of the tool 2 may be located inside the slot 7. The arrow F may show a tool longitudinal turning direction. The tool 2 may be configured to be turned around 180 degrees along its longitudinal axis X. In figure 2 the tool 2 has already been turned 180 degrees.
[0084] Figure 1c shows an example of the system, wherein the second end 9 of the tool 2 may be located inside the slot 7 of the user device 1 according to arrow C. The arrow C may show a direction to insert the tool 2 into the slot 7. The slot 7 may be accessed through the receiving space 6.
[0085] Figure 1d shows an example of the system, wherein the second end 9 of the tool 2 have been located inside the slot 7 of the user device 1. The tool 2 may be rotated in the slot 7 according to arrow D for disassembling the cover 3. The arrow D may show a tool rotation direction in the slot 7. The middle part 10 of the tool 2 may also push at the same time a side of the cover 3 upwards according to arrow E. The arrow E may be a cover lifting direction.
[0086] In the examples of figures 1a to 1c the lifting part is in a resting position and in the example of figure 1d the lifting part is in a lifting position.
[0087] An example of figure 3b shows a cross-section A-Aof figure 1d where the lifting part 11 is in resting position and before the lifting part has been turned and the cover has been lifted up. Figure 3c shows an example of a detail B-B of figure 3b.
[0088] According to an example embodiment, the user device 1 comprises a lifting part 11 located between the cover 3 and the slot 7. The lifting part 11 may be a tab or bollard. The bottom surface 17 of the lifting part 11 may be located above the slot 7. The bottom surface 17 may be located above the second end 9 of the tool 2 when the tool 2 is located in the slot 7. Thus, the second end 9 of the tool 2 may have direct contact to the bottom surface 17 of the lifting part 11. The lifting part 11 may have a form wherein a bottom surface 17 may have larger cross-section than a lifting surface 16 of the lifting part 11. On the other hand, the lifting part 11 may have a form wherein a bottom surface 17 may have smaller cross-section than a lifting surface 16 of the lifting part 11. The lifting part 11 may have a T shape form or an upside down T shape form as shown in figure 3c.
[0089] According to an example embodiment, the user device 1 further comprises a chassis 15 comprising a cavity 18 in which the lifting part 11 is located. The chassis 15 may limit movement of the lifting part 11 and may also receive transversal and perpendicular forces from the tool 2. The chassis 15 may be made of lightweight material. The material may be at least one of the following: plastic, composite, aluminum, and / or alloy. When the second end 9 of the tool 2 is inserted to the slot 7, after the card holder 5, such as SIM or memory tray, is removed, the chassis 15 may provide support when the tool 2 is turned and the second end 9 of the tool 2 may push the lifting part 11, which then may push the cover 3 up. The slot 7 may also not be located in connection with the receiving space 6.
[0090] According to an example embodiment, when the tool 2 is rotated in the slot 7, the lifting part 11 moves towards the cover 3 and lifts the cover 3 to the lifting position for disassembling the cover 3. When the tool 2 is rotated, the second end 9 of the tool 2 may touch the lifting part 11 and the lifting part 11 may lift the cover 3. The bottom surface 17 of the lifting part 11 may receive scratches caused by the second end 9 of the tool 2. This way the tool 2 may not scratch the cover 3 but only the lifting part 11. The lifting part may cause only perpendicular forces towards the cover 3 which forces may not harm the cover 3.
[0091] According to an example embodiment, when the tool 2 is rotated in the slot 7, the middle part 10 of the tool 2 is configured to lift the cover 3 for disassembling or helping to disassemble the cover 3. The middle part 10 may comprise a protrusion or an uppercase phi form, which may allow the middle part 10 to push a side 19 of the cover 3 upwards according to arrow E. The lifting part 11 and the middle part 10 may push the cover 3 upwards simultaneously.
[0092] According to an example embodiment, the tool 2 is configured to be rotated in the slot 7 clockwise or counterclockwise. The amount of the rotation may not be big. For example, it may be rotated 5 to 45 degrees or 10 to 45 degrees towards the lifting part 11.
[0093] Figure 4 illustrates an example of a method for disassembling a cover 3 of a user device 1 of a system.
