Abstract

Because it allows evaluation of whether internal components meet required specifications without operating or disassembling the product, it can promote the reuse of internal components and contribute to resource recycling that balances the business viability and environmental value of recycling companies. [Solution] The parts evaluation system uses an estimation model that shows the correlation between external information, which is the physical properties of the outside of the used product, and internal information, which shows the mechanical properties of the internal parts of the used product. By determining the mechanical properties of the internal parts corresponding to the external physical properties of the used product, the system estimates the internal information of the used product. If it is determined that the mechanical properties of the internal parts meet the required specifications, the system decides to reuse the internal parts. If it is determined that the mechanical properties of the internal parts do not meet the required specifications, the system decides to recycle the internal parts.

Description

Technical Field

[0001] The present invention relates to a component evaluation system, a component evaluation method, and a program.

Background Art

[0002] Used products are often recycled as materials after being disassembled and sorted by vein companies, and the materials targeted for recycling are recycled as products through processes such as processing.

[0003] Processes such as processing cause cost increases, so from the perspective of achieving both the profitability of vein companies and environmental value, a method for minimizing the processes required for recycling is demanded. One such method is the reuse of internal components at the component level in used products. Reuse at the component level is a method of circulating the internal components contained in used products in their original form without disassembling and processing them. Therefore, reuse can reduce environmental burdens such as the cost of processes and time and the amount of carbon dioxide emitted compared to recycling that returns used products to materials and recycles them. In addition, since the reused internal components can be incorporated into products without further processing, they are considered to have a higher market value than recycled materials.

[0004] The quality of internal components affects the quality of the products into which the internal components are incorporated. Therefore, it is necessary to determine whether reuse is possible depending on whether the internal components meet the required specifications. When checking the state of internal components during the determination, considerations such as removing the internal components from the product without damaging them need to be taken into account in view of the possibility of reuse, which is troublesome for vein companies. Therefore, a system that can determine whether reuse of internal components is possible without disassembling the product is demanded.

[0005] Furthermore, Patent Document 1 discloses a technology for determining whether or not a part can be reused. Specifically, Patent Document 1 states that "the operating sound of the collected product is measured (step S202), the part whose lifespan is to be diagnosed is determined, sounds other than the sound emitted by that part are removed as background noise (step S203), and the sound pressure, waveform, etc. at the extracted characteristic frequencies are analyzed (step S204). After this, if the standard value for recyclability / reusability is not exceeded (step S204: OK), it is determined to be a reusable / recyclable part (step S205). If the standard value is exceeded (step S204: NG), it is determined to be a recyclable item (step S206). The recycledness of each part can be evaluated by analyzing the sound pressure, waveform, etc. of the parts without disassembling the collected product 101." [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2003-149042 [Overview of the project] [Problems that the invention aims to solve]

[0007] The technology described in Patent Document 1 evaluates whether parts can be reused based on their operating sound without disassembling the product. However, such technology requires a process of supplying power to the product and operating it in order to check its operating sound. On the other hand, since recycling companies need to quickly make decisions on a wide variety of products, there is a demand for a technology that can determine whether internal parts can be reused without the hassle of disassembling or operating the product.

[0008] This invention has been made in view of the above-mentioned problems, and aims to evaluate whether the internal components of the product meet the required specifications without requiring operation or disassembly of the product. [Means for solving the problem]

[0009] This application includes several means for solving at least some of the above problems, but an example is as follows. A component evaluation system according to one aspect of the present invention that solves the above problems includes: a storage unit that stores an estimation model showing the correlation between external information, which is the physical property information of the outside of a used product that can be obtained without disassembling the product, and internal information, which is the mechanical property of the internal components of the used product that is difficult to obtain directly without disassembling the product; a product internal information estimation unit that estimates the internal information of a used product without disassembling and operating the product by using the estimation model to determine the mechanical property of the internal components corresponding to the physical property information of the outside of the used product; and a resource recycling method determination unit that determines the resource recycling method for the internal components to be reused if it is determined that the mechanical property of the internal components shown by the estimated internal information satisfies the required specifications, and determines the resource recycling method for the internal components to be recycled if it is determined that the mechanical property of the internal components shown by the internal information does not satisfy the required specifications. [Effects of the Invention]

[0010] According to the present invention, it is possible to evaluate whether internal components meet the required specifications without operating or disassembling the product. This promotes the reuse of internal components and contributes to resource recycling that balances the business viability and environmental value of recycling companies.

[0011] Furthermore, other issues, configurations, and effects will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0013] The following embodiments are examples for explaining the present invention, and for the sake of clarity of explanation, omissions and simplifications are made as appropriate. The present invention can be implemented in various other forms. Also, unless otherwise specified, each component may be singular or plural.

[0014] Also, the positions, sizes, shapes, ranges, etc. of each component shown in the drawings may not represent the actual positions, sizes, shapes, ranges, etc. in order to facilitate understanding of the invention. Therefore, the present invention is not necessarily limited to the positions, sizes, shapes, ranges, etc. disclosed in the drawings.

[0015] Also, as examples of various information, it may be described in expressions such as "table", "list", "queue", etc., but the various information may be represented by data structures other than these. For example, various information such as "XX table", "XX list", "XX queue" may be referred to as "XX information". When explaining identification information, expressions such as "identification information", "identifier", "name", "ID", "number", etc. are used, but these can be mutually replaced.

[0016] Also, when there are a plurality of components having the same or similar functions, they may be described with the same reference numeral and different subscripts. Also, when it is not necessary to distinguish these plurality of components, the subscripts may be omitted in the description.

[0017] Also, in the embodiments, the processes performed by executing the program may be described. Here, the computer executes the program by a processor (e.g., CPU, GPU), and performs the processes defined by the program while using storage resources (e.g., memory) and interface devices (e.g., communication ports), etc. Therefore, the subject of the processes performed by executing the program may be the processor.

[0018] Similarly, the subject of the processes performed by executing the program may be a controller, a device, a system, a computer, or a node having a processor. The subject of the processes performed by executing the program only needs to be an arithmetic unit, and may include a dedicated circuit for performing specific processes. Here, the dedicated circuit is, for example, an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), a CPLD (Complex Programmable Logic Device), etc.

[0019] The program may be installed in the computer from a program source. The program source may be, for example, a program distribution server or a storage medium readable by the computer. When the program source is a program distribution server, the program distribution server includes a processor and a storage resource for storing the program to be distributed, and the processor of the program distribution server may distribute the program to be distributed to other computers. Also, in the embodiments, two or more programs may be realized as one program, or one program may be realized as two or more programs.

[0020] Hereinafter, each embodiment of the present invention will be described with reference to the drawings.

[0021] <First Embodiment> <Schematic Configuration of Component Evaluation System 1000> Figure 1 shows an example of the schematic configuration of the component evaluation system 1000 according to this embodiment. The component evaluation system 1000 is a system that determines whether or not internal components can be reused by estimating internal information of a product from external information of the product.

[0022] Specifically, the parts evaluation system 1000 acquires identification information of used products and obtains an estimation model corresponding to those products.

[0023] Furthermore, the parts evaluation system 1000 uses the acquired estimation model and external information of the used product (e.g., physical properties of the product's exterior) to estimate the internal information of the product (e.g., information indicating the mechanical properties of the internal components).

[0024] Furthermore, the parts evaluation system 1000 determines whether the condition of the internal parts of a used product meets the required specifications, thereby determining the appropriate method of resource recycling (reuse or recycling).

[0025] Furthermore, the parts evaluation system 1000 presents the evaluation results to the user.

[0026] Such a component evaluation system allows for the assessment of whether internal components meet the required specifications without requiring the product to be operated or disassembled.

[0027] The following explanation uses an example where a used electric motor is considered a used product, and its internal component is the rotor.

[0028] <Details of the parts evaluation system 1000> The component evaluation system 1000 is constructed using a computer 100, such as a cloud server or a personal computer. The component evaluation system 1000 also acquires information input by a user via a predetermined device (for example, a personal computer, smartphone, or tablet terminal; hereinafter sometimes referred to as a user device) and performs processing to evaluate the component. The component evaluation system 1000 may also acquire input information via an input device provided by the computer 100 (for example, a keyboard, mouse, or touch panel). The following explanation assumes that the component evaluation system 1000 acquires various types of input information from the user device.

[0029] As shown in Figure 1, the component evaluation system 1000 includes a processing unit 110, a storage unit 120, and a communication unit 130.

[0030] The processing unit 110 is a functional unit that performs processing executed by the component evaluation system 1000. Specifically, the processing unit 110 has the following individual functional units that perform each processing: a product identification information acquisition unit 111, a product external information acquisition unit 112, a product internal information estimation unit 113, a requirements specification acquisition unit 114, a resource recycling method determination unit 115, and a display unit 116.

[0031] The product identification information acquisition unit 111 is a functional unit that acquires identification information of used products from the user's device. The type of identification information is not limited, but examples include the product model number and product name.

[0032] The product external information acquisition unit 112 is a functional unit that acquires external information of used products from the user's device. Here, the external information of used products refers to physical property information of the outside of the product that can be acquired without disassembling the product, such as chemical information indicating the degree of deterioration of the product's surface material.

[0033] As an example of external product information, the carbonyl index of the resin component forming the product surface is used. The carbonyl index is obtained from the 1715 cm⁻¹ spectrum of the resin using Fourier Transform Infrared Spectroscopy (FT-IR). -1 The absorbance of the carbonyl group in the vicinity was measured at 1458 cm⁻¹. -1 This value is obtained by dividing by the absorbance of the CH bending vibration in the vicinity, and it is characterized by an increase in value as the resin deteriorates.

[0034] The internal product information estimation unit 113 is a functional unit that estimates the internal information of a used product. Here, the internal information of a used product refers to mechanical information that correlates with the external information of the product and indicates the mechanical properties of internal components that are difficult to obtain directly without disassembling the product. A specific example of internal information is information indicating the degree of deterioration of the coating agent used in the internal components (a more specific example being the adhesive strength of the adhesive).

[0035] The product internal information estimation unit 113 uses an estimation model that shows the correlation between external and internal information of a used product, and the external information, to estimate the internal information of the product, i.e., the mechanical properties of its internal components, without disassembling or operating the product.

[0036] The requirements specification acquisition unit 114 is a functional unit that acquires requirements specifications for internal components of used products from the user's device.

[0037] The resource recycling method determination unit 115 is a functional unit that determines the method of resource recycling, such as reuse or recycling. Specifically, the resource recycling method determination unit 115 determines whether the appropriate resource recycling method is reuse or recycling based on the estimated internal information, i.e., whether the mechanical properties of the internal components meet the required specifications.

[0038] The display unit 116 is a functional unit that displays predetermined screen information. Specifically, when the display unit 116 acquires various types of information from the user, it generates screen information for accepting information input and displays it on the user device. The display unit 116 also generates screen information indicating the determined optimal resource recycling method (reuse or recycle) and displays it on the user device.

[0039] Next, the memory unit 120 will be described. The memory unit 120 is a functional unit for storing various types of information. Specifically, the memory unit 120 has an estimated model DB (Database) 121.

[0040] The estimation model DB121 is a database that stores estimation models for used products. These estimation models show the correlation between external and internal information about used products.

[0041] Figure 2 is a schematic diagram showing an example of an estimation model. As shown in the figure, the estimation model uses external information of a used product on the horizontal axis and internal information of a used product on the vertical axis, showing the correlation between the two. Specifically, the estimation model shown indicates that when the value of the external information of a used product (electric motor) (for example, the carbonyl index of the resin parts forming the product surface) is X, the estimated value of the internal information of the used product (for example, the adhesive strength of the magnet fixing adhesive used in the rotor, which is an internal component) is Y.

[0042] Such estimation models are stored in the estimation model DB121, with, for example, the identification information of the corresponding used product and an arbitrary model number associated with them. The method for generating the estimation model will be described in the second embodiment below.

[0043] Next, the communication unit 130 will be described. The communication unit 130 is a functional unit that communicates information with external devices (for example, user devices or information providing devices) via the network N. Specifically, the communication unit 130 acquires information used in processing performed by the component evaluation system 1000 (for example, estimation models and test results used to generate estimation models) from external devices. The communication unit 130 also transmits information generated by the component evaluation system 1000 (for example, screen information for accepting input and information indicating resource circulation methods) to external devices (for example, user devices). The network N is a communication network such as the Internet or a LAN (Local Area Network).

[0044] <Component evaluation process> Next, the component evaluation process performed by the component evaluation system 1000 will be described.

[0045] Figure 3 is a flowchart showing an example of a component evaluation process. Figure 4 is a diagram illustrating the component evaluation process along with the data flow. The component evaluation system 1000 starts the process when it receives an execution instruction from a user device, for example.

[0046] When processing begins, the product identification information acquisition unit 111 acquires identification information of the used product to be processed from the user device (step S10).

[0047] Next, the product internal information estimation unit 113 obtains an estimation model from the estimation model DB 121 to which the identification information of the used product obtained in step S10 is associated (step S11).

[0048] Next, the product external information acquisition unit 112 acquires external information of the used product (step S12). In this example, the product external information acquisition unit 112 acquires the carbonyl index of the resin component on the surface of the electric motor from the user's device.

[0049] Next, the product internal information estimation unit 113 estimates the internal information of the product (step S13). In this example, the product internal information estimation unit 113 uses the estimation model obtained in step S11 and the carbonyl index value of the electric motor obtained in step S12 to estimate the adhesive strength of the rotor adhesive. This identifies estimated values ​​that indicate the mechanical properties of the internal components.

[0050] Next, the requirements specification acquisition unit 114 acquires the requirements specifications for the internal components (step S14). In this example, the requirements specification acquisition unit 114 acquires the requirements specifications required when reusing the rotor from the user's device.

[0051] Next, the resource recycling method determination unit 115 determines whether the internal information of the product meets the required specifications (step S15). In this example, the resource recycling method determination unit 115 makes the determination based on a comparison between the estimated adhesive strength value estimated in step S13 and the required specifications obtained in step S14.

[0052] If the system determines that the requirements are met (Yes in step S15), the resource recycling method determination unit 115 decides that the resource recycling method is "reuse" (step S16). On the other hand, if the system determines that the requirements are not met (No in step S15), the resource recycling method determination unit 115 decides that the resource recycling method is "recycle" (step S17).

[0053] Next, the display unit 116 displays the determined resource recycling method (step S18). Specifically, the display unit 116 generates screen information for displaying the resource recycling method and displays it on the user device via the communication unit 130. The screen information includes at least the name of the internal component (rotor in this example) and the type of appropriate recycling method determined, i.e., "reuse" or "recycle". For example, the display unit 116 displays screen information on the user device that reads, "The appropriate recycling method for the component (rotor in this example) is reuse (or recycle)."

[0054] Furthermore, the display unit 116 terminates the processing of this flow once it has displayed the resource recycling method on the user device.

[0055] The above explains the component evaluation process.

[0056] Such a component evaluation system allows for the assessment of whether internal components meet required specifications without the need for product operation or disassembly. In particular, the component evaluation system can evaluate the mechanical properties of internal components from the physical properties information of the product's surface material to determine whether reuse at the component level of a used product is appropriate. Therefore, the component evaluation system can determine an appropriate method of resource recycling without the need for product operation or disassembly. As a result, the component evaluation system can promote the reuse of internal components and contribute to resource recycling that balances the business viability and environmental value of recycling companies.

[0057] Furthermore, if a single used product contains multiple internal components that are candidates for processing, the product identification information acquisition unit 111 obtains the identification information of the target internal component (e.g., the part number or part name of the internal component) from the user along with the identification information of the used product. In this case, it is sufficient that the identification information of the internal component is already associated with the identification information of the used product in the estimation model. As a result, the product internal information estimation unit 113 can obtain an estimation model corresponding to the combination of the used product and internal component to be processed from the estimation model DB 121 and use it for component evaluation processing. In addition, even if the same product contains multiple internal components that are candidates for processing, the user can specify the internal component for which they want to estimate the internal information.

[0058] <Second Embodiment> Figure 5 is a diagram showing an example of the schematic configuration of the component evaluation system 1000 according to the second embodiment. As shown in the figure, the component evaluation system 1000 of this embodiment has a test result acquisition unit 117 and an estimation model generation unit 118, which are functional units involved in the generation of an estimation model. Since the basic configuration of the component evaluation system 1000 is the same as that of the first embodiment, the following description will focus on the different functions and processes, and components common to the first embodiment will be denoted by the same reference numerals and detailed descriptions will be omitted.

[0059] The test result acquisition unit 117 is a functional unit that acquires test results showing the relationship (correlation) between external and internal information of used products that are the target of estimation model generation. The test and test results will now be explained.

[0060] Figure 6 shows an example of test results. As illustrated, an accelerated test is assumed as an example of the test. An accelerated test is a test that applies more severe conditions than normal use conditions in order to evaluate the degradation of products and materials in a short period of time. Furthermore, the test is performed on the same material as the external physical properties information of the used product (for example, the surface material of the product or the material of the parts forming the surface) (hereinafter sometimes referred to as the material equivalent to external information), and on the same material used in the internal parts of the used product that exhibits the mechanical properties of the internal parts (hereinafter sometimes referred to as the material equivalent to internal information).

[0061] Furthermore, the test evaluates chemical information of the material equivalent to external information (e.g., carbonyl index indicating the degree of degradation) and mechanical information indicating the mechanical properties of the material equivalent to internal information (e.g., information indicating the degree of degradation of the coating agent) for each test time of different lengths (in the illustrated example, T1: e.g., 1 hour, T1-T2: e.g., 10 hours, T1-T3: e.g., 100 hours). The test result acquisition unit 117 acquires the set of chemical and mechanical information for the same test time as the test result.

[0062] The estimation model generation unit 118 is a functional unit that generates an estimation model based on a predetermined algorithm using test results. Specifically, the estimation model generation unit 118 generates an estimation model for estimating internal information from external information of a used product by fitting the test results, using a predetermined algorithm such as the least squares method or machine learning. The type of algorithm used to generate the estimation model is not limited.

[0063] <Estimation Model Generation Process> Next, we will describe the estimation model generation process performed in the component evaluation system 1000.

[0064] Figure 7 is a flowchart illustrating an example of the estimation model generation process. Figure 8 is a diagram illustrating the estimation model generation process along with the data flow. The component evaluation system 1000 starts the process, for example, when it receives an execution instruction from a user device.

[0065] Once processing begins, the test result acquisition unit 117 acquires test results from, for example, an external device (such as an information providing device that has test data) (step S20). Specifically, the test result acquisition unit 117 acquires a set of test results for materials corresponding to external information and materials corresponding to internal information.

[0066] Next, the estimation model generation unit 118 generates an estimation model (step S21). Specifically, the estimation model generation unit 118 uses the test results to generate an estimation model for estimating internal information from external information of a used product based on a predetermined algorithm.

[0067] Next, the estimation model generation unit 118 obtains identification information of used products to be associated with the estimation model from an external device (for example, a device used by a user who manages the generation of estimation models) via the product identification information acquisition unit 111 (step S22), and stores it in the estimation model DB 121, associating it with the estimation model along with an arbitrary model number (step S23). After completing the process in step S23, the estimation model generation unit 118 terminates the processing of this flow.

[0068] The above explains the estimation model generation process.

[0069] Such a component evaluation system can generate an estimation model for predicting the mechanical properties of internal components from the physical properties information of the product's surface material. Using the generated estimation model, the component evaluation system can evaluate whether the internal components meet the required specifications without requiring the product to be operated or disassembled.

[0070] In the embodiments described above, an electric motor was used as a used product and a rotor was used as an example of its internal component. However, the used products and internal components targeted by the component evaluation system 1000 are not limited to these. The component evaluation system 1000 can use estimation models that correspond to various types of used products, such as a refrigerator as the used product and a compressor as its internal component, to estimate internal information from external information of a product and determine an appropriate method for resource recycling.

[0071] Furthermore, the estimation model described in the first embodiment may be an estimation model generated by the estimation model generation unit 118 described in the second embodiment, or the component evaluation system 1000 may acquire estimation models generated by an external device having functional units equivalent to the test result acquisition unit 117 and the estimation model generation unit 118, and use them to estimate the internal information of the used product.

[0072] <Hardware configuration of component evaluation system 1000> Figure 9 shows an example of the hardware configuration of the component evaluation system 1000. As shown in the figure, the component evaluation system 1000 includes an input device 210, a display device 220, a processing device 230, a main memory 240, an auxiliary memory 250, a communication device 260, and a bus 270 that electrically interconnects these.

[0073] The input device 210 is, for example, an input device such as a touch panel, keyboard, or mouse. The display device 220 is a display device such as a liquid crystal display or an organic display.

[0074] The processing unit 230 is, for example, a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The main memory 240 is a memory device (memory resource) such as RAM (Random Access Memory) or ROM (Read Only Memory). The component evaluation system 1000 has at least one processor and memory resources.

[0075] The auxiliary storage device 250 is a non-volatile storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory that can store digital information.

[0076] The communication device 260 is either a wired communication device that performs wired communication via a network cable, or a wireless communication device that performs wireless communication via an antenna.

[0077] The above describes an example of the hardware configuration of the component evaluation system 1000.

[0078] The processing unit 110 of such a component evaluation system 1000 is implemented by a program that causes the processing unit 230 to perform processing. This program is stored in the main memory 240 or the auxiliary memory 250, and when the program is executed, it is loaded into the main memory 240 and executed by the processing unit 230.

[0079] Furthermore, the storage unit 120 is implemented by a main memory 240, an auxiliary memory 250, or a combination thereof. The communication unit 130 is implemented by a communication device 260.

[0080] Furthermore, some or all of the above configurations, functions, processing units, and processing means of the component evaluation system 1000 may be implemented in hardware, for example, by designing them as integrated circuits. Alternatively, the above configurations and functions may be implemented in software by having a processor interpret and execute programs that implement each function. Information such as programs, tables, and files that implement each function can be stored in memory, hard disks, SSDs, or other storage devices, or in recording media such as IC cards, SD cards, and DVDs.

[0081] Furthermore, the present invention is not limited to the embodiments and modifications described above, but includes various modifications within the scope of the same technical idea. For example, the embodiments described above are described in detail to make the present invention easier to understand, and are not necessarily limited to those having all the configurations described. Also, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace parts of the configuration of each embodiment with other configurations.

In reality, it is safe to assume that almost all components are interconnected. [Explanation of Symbols]
