Background

After the electronic device is sold, the producer typically provides the consumer with a warranty period for a period of time, such as: the purchased mobile phone has external faults and internal faults (excluding software faults) which are not damaged by people, and can enjoy a one-year warranty period. Because accessories such as the mainboard, the battery and the like have higher values, a producer generally cannot accept the detached mobile phone so as to guarantee the reputation and reduce the loss. Therefore, when the producer receives the faulty mobile phone of the consumer, it is generally determined whether the consumer has taken the phone apart privately (or has looked for a third party) to determine whether the faulty mobile phone satisfies the maintenance condition.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments. In the description herein, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

The inventors of the present application have found, through long-term research: at present, measures for preventing a non-production party from disassembling an electronic product are generally as follows: the surface of a fastener (such as a screw) of the electronic equipment is covered with a layer of fragile sticker. When a consumer personally (or finds a third party) to disassemble the machine, the fragile sticker needs to be damaged, so that the disassembling mark is left for the convenience of identification of a production party. However, for actual anti-private detachment, due to the fragile characteristic of the fragile sticker, the situation that the fragile sticker is damaged because the electronic device is not detached easily occurs, which undoubtedly will affect the determination of whether the electronic product is detached by the private of the consumer (or finding a third party), and further easily causes the contradiction between the consumer and the production plant, and affects the brand image. In addition, the fragile sticker is arranged in the electronic equipment, so that extra material cost and labor cost are increased. To this end, the present application proposes the following examples.

The electronic equipment can be a mobile phone, a tablet computer, a notebook computer, wearable equipment and the like. In the present application, a mobile phone is taken as an example for explanation. The mobile phone generally includes a rear cover, a display screen and a middle frame sandwiched between the rear cover and the display screen, and some structural and functional components are required to be placed in order to obtain a mobile phone with complete structure and function. For example, the upper cover bracket, the battery cover, the main board, the small board, the camera module and other components may need to be connected with the middle frame through fasteners such as buckles and screws, so that some positions to be fastened are reserved on the middle frame in advance to accommodate the fasteners. Accordingly, when the parameters of the main board are checked, the battery is replaced or the mobile phone fails, the fasteners need to be removed so as to disassemble the mobile phone. The present application is described with reference to the example where the fastener is a screw and the fastener is a screw hole.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a first embodiment of a method for determining whether an electronic device is detached. The method comprises the following steps:

step S101: a factory number order for a plurality of fasteners is obtained.

The electronic equipment is provided with a plurality of positions to be fastened, and the positions to be fastened are used for accommodating fasteners to assemble the electronic equipment. The positions, the number, the types and the like of the electronic devices to be fastened and retained generally vary according to the arrangement of the components inside the electronic devices and the assembly process; however, for a certain type of electronic equipment, as shown in fig. 2, the position, number, type, and the like to be retained by fastening are generally fixed. Therefore, for a certain model of electronic equipment, a plurality of positions to be fastened in the electronic equipment can be numbered according to a first rule and a first factory number sequence can be generated.

In some embodiments, the first rule includes a numbering order, a numbering type. The numbering sequence may be clockwise, counterclockwise, etc., and the present embodiment takes numbering the screws in the clockwise direction as an example for explanation; the number type may be upper case english alphabet, lower case english alphabet, roman numeral, arabic numeral, etc., and this embodiment is described by taking the example of numbering screws with upper case english alphabet. In other embodiments, the first rule further includes a numbering gradient corresponding to the type of the bit to be tightened, e.g., screw holes that are to be tightened to three types, M1.2, M1.4, and M1.6, which may be divided into three numbering gradients from small to large and separated by "/" signs; of course, it is also possible not to divide this strictly, but to treat all types of bits to be fastened as identical. In still other embodiments, the first rule further comprises a continuity of numbering; in other words, the numbering may be continuous or discontinuous.

In this embodiment, the first factory serial number sequence is a string of characters arranged according to a certain rule and containing certain information. For example: for the distribution of a plurality of bits to be fastened as shown in fig. 2, if numbering is performed according to the first rule described above: 1) in a clockwise direction, 2) using capital english letters, 3) treating all the bits to be fastened as identical and 4) the numbering is continuous, then the first factory numbering order is ABCDEFG.

Optionally, to increase the reliability of tamper resistance, each of the numbers corresponding to the positions to be secured is not identified on the electronic device. Further, only the bit to be fastened, numbered a, may be identified as the start bit of the first factory number sequence, as shown in fig. 2. In other embodiments, each number to be secured may be stored directly in the electronic device or server in the form of a distribution map, as shown in fig. 3.

Furthermore, the plurality of fasteners are provided with identification symbols which are numbered according to a second rule, and the plurality of fasteners are randomly arranged at the plurality of positions to be fastened, so that the identification symbols on the plurality of fasteners generate a second factory numbering sequence.

In some embodiments, the second rule includes a number type, a number of numbers. The number type may be upper case english alphabet, lower case english alphabet, roman numeral, arabic numeral, etc., and this embodiment takes the case of numbering screws by using arabic numerals as an example for explanation; the number of numbers may be nine different digits such as 1-9, six different digits such as 1-6, etc. In other embodiments, the second rule further comprises a continuity of numbering; in other words, the numbering may be continuous or discontinuous.

In this embodiment, the identification symbol is a number such as an arabic numeral 1,2, 9 provided on the fastener. In other embodiments, the identification symbol may be a shape such as "+", "-", "Δ", "-". Further, the present embodiment does not consider the type of fastener itself, such as: the three types of screws M1.2, M1.4 and M1.6 are not distinguished, but are considered to be identical.

Alternatively, in order to increase the reliability against the tampering, an identification symbol is provided on the back face of the fastener, in other words, the identification symbol on the fastener is not visible after the fastener is provided in the place to be fastened. In other embodiments, the identifier may be provided on the front of the fastener if it is merely convenient to view the identifier on the fastener.

The fasteners are numbered according to the second rule in advance, and then the fasteners are randomly selected and arranged at the positions to be fastened, each position to be fastened corresponds to the fasteners with various possible numbers, so that the second factory numbering sequence has randomness. Further, when all the positions to be fastened are provided with fasteners, the second factory number sequence is uniquely determined.

In this embodiment, the second factory serial number sequence is a string of characters arranged according to a certain rule and containing certain information. For example: the identification symbols of arabic numerals 1 to 9 are previously provided on 900 screws according to the second rule, specifically, 100 screws are numbered 1,100 screws are numbered 2, …,100 screws are numbered 9, and then they are mixed together. Obviously, when a screw is randomly selected to be placed in a screw hole, there are nine possibilities for the identification symbol on the screw. Further, if there are seven screw holes on the mobile phone, as shown in fig. 2, and they are numbered according to the first rule, and the number of the randomly selected screw of the first screw hole (a) is 9, the number of the randomly selected screw of the second screw hole (B) is 7, the number of the randomly selected screw of the third screw hole (C) is 6, the number of the randomly selected screw of the fourth screw hole (D) is 9, the number of the randomly selected screw of the fifth screw hole (E) is 1, the number of the randomly selected screw of the sixth screw hole (F) is 3, and the number of the randomly selected screw of the third screw hole (G) is 4, then the second factory numbering sequence is 9769134.

Further, the factory numbering sequence includes a factory correspondence between the second factory numbering sequence and the first factory numbering sequence, that is, a correspondence between the fastening member and the to-be-fastened position after the electronic device is assembled. Based on the above description, the factory numbering sequence of the embodiment may be A9B7C6D9E1F3G4, or A9-B7-C6-D9-E1-F3-G4; also can be G4-F3-E1-D9-C6-B7-A9.

Optionally, the factory number sequence is written into the electronic device, and can be obtained only by inputting a specific code, scanning the tamper-proof barcode or the two-dimensional code, and the like, so as to increase the difficulty of a consumer (or a third party) in obtaining the factory number sequence, thereby increasing the reliability of tamper-proof. In other embodiments, when the factory number sequence of a plurality of fasteners is obtained, a distribution map corresponding to the plurality of fasteners can be additionally obtained, so that the visual property of preventing the private dismantling is increased.

Accordingly, in this embodiment, the manner of obtaining the factory number sequence of the plurality of fasteners may be to scan a tamper-proof barcode or a two-dimensional code on the electronic device.

Step S102: the actual numbering order of the plurality of fasteners is detected.

Optionally, as shown in fig. 4, the step specifically includes:

step S1021: the identification symbols on the plurality of fasteners are viewed.

As described above, in some embodiments, the identification symbol is provided on the front of the fastener, either directly viewable by a service person or identifiable by an authentication device. In other embodiments, the identifier is provided on the back of the fastener and the service person needs to remove the fastener from the location to be fastened in order to view the identifier thereon.

Step S1022: and generating an actual numbering sequence according to the actual corresponding relation between the plurality of fasteners and the plurality of positions to be fastened and the identification symbols.

Since the factory code sequence of a plurality of fasteners has been obtained, a plurality of codes or profiles to be secured are known. When the identification symbol on each fastener to be fastened and retained is checked, the actual corresponding relation can be recorded one by one, and accordingly, the actual numbering sequence is obtained. For example: if the identifier on the fastener to which the a-point is to be fastened is 9, then the actual correspondence is a 9. Obviously, the actual numbering sequence can be obtained by sequentially checking and recording other actual corresponding relations.

Step S103: and judging whether the actual numbering sequence is consistent with the factory numbering sequence or not.

Based on the analysis, after the factory numbering sequences of the plurality of fasteners are obtained and the actual factory numbering sequences of the plurality of fasteners are detected, the actual factory numbering sequences can be judged whether to be consistent with the factory numbering sequences or not only by comparing the actual factory numbering sequences with the factory numbering sequences. Of course, the judgment process can be completed by a maintenance person or an authentication device.

When the judgment result of the step S103 is no, step S104 is executed; on the contrary, if the determination result in step S103 is yes, step S105 is executed.

Step S104: the electronic device is privately detached.

Under the condition that the electronic equipment is privately dismounted, the producer can refuse to provide the maintenance service within the warranty period for the consumer, and can also provide the paid maintenance service for the consumer.

Step S105: the electronic device has not been privately removed.

In the event that it is determined that the electronic device has not been privately removed, the producer needs to fulfill a commitment to provide the consumer with maintenance services within the warranty period for a fee.

In some embodiments, if the above determination process is performed by the authentication device, the determination result may be prompted by a screen display, a sound, an indicator light, or the like.

The following is a practical example:

after a maintenance worker receives a fault mobile phone of a consumer, the maintenance worker firstly obtains a factory numbering sequence of a plurality of fasteners of the fault mobile phone, then detects an actual numbering sequence of the plurality of fasteners, compares the actual numbering sequence with the factory numbering sequence to judge whether the actual numbering sequence is consistent with the factory numbering sequence, and finally gives a judgment result and informs the consumer whether to provide maintenance service for the consumer. Of course, the whole process can be completed by the authentication device. Specifically, as shown in table 1 below, if the checking result is #1 and the corresponding actual numbering sequence is #1, the checking result is compared with the factory numbering sequence, and it can be found that the checking result and the factory numbering sequence are identical, so that a conclusion that the mobile phone has not been privately detached can be obtained; if the checking result is #2 and the corresponding actual numbering sequence is #2, the checking result is compared with the factory numbering sequence, and the checking result and the factory numbering sequence are inconsistent, so that the conclusion that the mobile phone is privately detached can be obtained.

Table 1:

through the mode, after the fault electronic equipment of a consumer is received by a production party, only the factory number sequence of the plurality of fasteners on the electronic equipment needs to be acquired, the actual factory number sequence of the plurality of fasteners is detected, and then the actual factory number sequence and the factory number sequence are compared, so that whether the actual number sequence is consistent with the factory number sequence or not can be judged, and whether the electronic equipment is privately dismounted is judged. Obviously, the judgment process is simple and efficient, and the judgment result is obvious and reliable.

Referring to fig. 5, fig. 5 is a flowchart illustrating a second embodiment of a method for determining whether an electronic device is detached from a device according to the present application. The method comprises the following steps:

step S201: it is determined whether there is damage to the plurality of fasteners.

Damage in this application can indicate that the fastener condition such as lacquer, burr, fracture appear falling, also can indicate that the fragile piece of preventing tearing such as subsides that set up on the fastener condition such as breakage appears, peel off. Clearly, when such damage to the fastener occurs, the service person has reason to suspect that the customer has taken the machine by himself (or by looking for a third party).

During the design and assembly of the electronic device, a certain structure or functional component may be fixed by one or more specific fasteners. Then, by determining whether the one or more fasteners are damaged, it can be quickly predicted whether the corresponding component is disassembled. For example: after the maintenance personnel receive the fault mobile phone of the consumer, the damage evaluation can be carried out on the screw for fixing the battery cover so as to prejudge whether the consumer changes the battery privately (or finds a third party). Of course, the whole process can be completed by the authentication device. Further, if only one or two fasteners are suspected of being damaged, this is not the case.

When the judgment result of step S201 is yes, step S205 is executed; on the contrary, when the determination result of step S201 is no, step S202 to step S206 are executed.

Step S202: a factory number order for a plurality of fasteners is obtained.

Step S203: the actual numbering order of the plurality of fasteners is detected.

Step S204: and judging whether the actual numbering sequence is consistent with the factory numbering sequence or not.

When the determination result of step S204 is no, step S205 is executed; on the contrary, if the determination result in step S204 is yes, step S206 is executed.

Step S205: the electronic device is privately detached.

Step S206: the electronic device has not been privately removed.

Referring to fig. 6, fig. 6 is a schematic flowchart of a third embodiment of a method for determining whether an electronic device is detached from a device according to the present application. The method comprises the following steps:

step S301: a factory number order for a plurality of fasteners is obtained.

Step S302: and judging whether the factory serial number sequence comprises a maintenance identification code.

After the electronic device is purchased by a consumer, there may be multiple repairs, each of which may require removal of the fasteners. Then, after the nth repair of the electronic device by the manufacturer, the fastener may have been damaged without replacement; obviously, it is necessary to record the nth repair fact in some way so that the manufacturer can determine whether the fastener is damaged by the customer (or a third party) or the manufacturer when the manufacturer performs the (N + 1) th repair on the electronic device. Wherein, N can be a natural number such as 0,1,2, etc.

In this embodiment, the repair identification code is used to record the nth repair fact that the manufacturer performed on the electronic device. Wherein the service identification code may be composed of an identifier such as "#" and an arabic number. For example: after the electronic device is maintained for the first time by the manufacturer, the anti-tamper barcode or the two-dimensional code on the electronic device may be scanned, and the fact of the maintenance is recorded in the factory serial number sequence in the form of a maintenance identification code "# 1". Further, the service identification code may further record information such as a date of the nth service of the electronic device, a service profile, and the like.

If the determination result in step S302 is yes, step S303 is executed; on the contrary, when the determination result of step S302 is no, steps S304 to S307 are performed.

Step S303: the electronic device is removed by the manufacturer.

In the present application, the production party may be a manufacturer that produces the electronic device, and may further include an official entity store, an after-sales service store, a shop counter, and the like specified by the production party.

Step S304: the actual numbering order of the plurality of fasteners is detected.

Step S305: and judging whether the actual numbering sequence is consistent with the factory numbering sequence or not.

When the determination result of step S305 is no, step S306 is executed; on the contrary, if the determination result in step S305 is yes, step S307 is executed.

Step S306: the electronic device is privately detached.

Step S307: the electronic device has not been privately removed.
