Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, apparatus, computer equipment, and storage medium for determining product packaging. Background Art

[0002] Nowadays, household appliances often drop during transportation and handling. Therefore, the reliability and impact resistance of product packaging are becoming increasingly important. Drop simulation can verify the reliability and impact resistance of product packaging during the design phase, providing data support for product packaging design and shortening the product packaging development cycle.

[0003] However, if the designed product packaging fails to meet the drop requirements after a drop simulation, the designer must adjust the packaging structure based on their experience. The designer then repeats the drop simulation until the modified packaging meets the drop requirements. Because the designer's structural adjustments are based on personal experience, the design phase of the product packaging is a continuous process of verification and revision, which results in a long design cycle.

[0050] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] The following will describe in detail a method for determining product packaging provided by an embodiment of the present application in conjunction with specific implementation methods. Figure 1 This is a flow chart of a method for determining product packaging provided in an embodiment of the present application, such as Figure 1 The specific steps are as follows:

[0052] Step 101: construct a first finite element model corresponding to the product packaging of the household appliance based on the product structure and the weight of the household appliance.

[0053] In practice, the structure of the product's outer packaging depends on the product structure of the household appliance. At the same time, in the drop simulation test, the impact energy of the product packaging when it falls depends on the weight of the entire household appliance (since the packaging material of the product packaging is usually a lightweight material such as foam, the weight of the product packaging itself can be ignored) and the drop height. Therefore, when the computer constructs the finite element model of the product packaging, it is necessary to construct a first finite element model corresponding to the product packaging of the household appliance based on the product structure and the weight of the entire household appliance. Among them, the first finite element model is a finite element model in which the product packaging completely wraps the household appliance, the packaging thickness of each packaging surface is the initial packaging thickness, and the contact area is the initial contact area.

[0054] For example, taking the range hood as an example, the product structure of the range hood is as follows: Figure 2 As shown, the first finite element model corresponding to the product packaging of the range hood is as follows Figure 3 shown.

[0055] Step 102 involves performing a drop simulation test on each second finite element model corresponding to each package surface of the product package at each preset package thickness, based on a preset drop height, to determine a target package thickness for that package surface that satisfies the first preset drop energy absorption condition. A second finite element model is constructed based on the first finite element model and a preset package thickness corresponding to the package surface.

[0056] In practice, since the product structure of household appliances is asymmetric, the structure of the product packaging is also asymmetric. In this way, when the product packaging is subjected to a drop simulation test with different packaging surfaces, the impact energy that can be absorbed by different packaging surfaces of the same thickness is completely different. On the basis of ensuring that each packaging surface of the product packaging can meet the drop energy absorption condition (i.e., the first preset drop energy absorption condition), in order to reduce the size of the product packaging, the different packaging surfaces of the product packaging can be designed to have different packaging thicknesses. For each packaging surface of the product packaging, the computer can construct a second finite element model based on the first finite element model and a preset packaging thickness corresponding to the packaging surface. The first finite element model and the second finite element model have different packaging thicknesses on the packaging surface, but the contact area is the same. Then, the computer device can perform a drop simulation test on each second finite element model corresponding to the packaging surface under each preset packaging thickness based on the preset drop height, and determine the target packaging thickness of the packaging surface that meets the first preset drop energy absorption condition.

[0057] As an optional embodiment, the computer performs a drop simulation test on each second finite element model corresponding to the package surface at each preset package thickness based on a preset drop height, and the processing steps for determining the target package thickness of the package surface that meets the first preset drop energy absorption condition are as follows:

[0058] Step 1: Based on a preset drop height, a drop simulation test is performed on each second finite element model corresponding to the packaging surface under each preset packaging thickness to obtain each first energy absorption ratio corresponding to the packaging surface under each preset packaging thickness.

[0059] In implementation, the computer performs a drop simulation test on each second finite element model corresponding to the packaging surface under each preset packaging thickness based on the preset drop height, and outputs the energy absorption curve corresponding to the packaging surface under each preset packaging thickness (such as Figure 4 As shown, Figure 4 For each preset packaging thickness, the computer first determines the maximum energy absorption in the energy absorption curve corresponding to the packaging surface under the preset packaging thickness (i.e. Figure 4 The maximum peak value of the energy absorption curve in the package is obtained. Then, the computer determines the ratio of the maximum energy absorption to the impact energy received by the package surface as the first energy absorption ratio corresponding to the package surface under the preset package thickness. Similarly, the computer device can obtain the first energy absorption ratio corresponding to the package surface under each preset package thickness. The impact energy received by the package surface is Figure 4 The solid line in FIG, the impact energy = the weight of the household appliance × the preset drop height × the gravity coefficient.

[0060] Step 2: Among the preset packaging thicknesses whose first energy absorption ratio is greater than or equal to the first preset energy absorption ratio threshold, determine the minimum preset packaging thickness as the target packaging thickness of the packaging surface that meets the first preset drop energy absorption condition.

[0061] During implementation, after obtaining the first energy absorption percentages corresponding to the packaging surface at each preset packaging thickness, the computer can further determine the minimum preset packaging thickness among the preset packaging thicknesses for which the first energy absorption percentage is greater than or equal to a first preset energy absorption percentage threshold (the first preset energy absorption percentage threshold is the minimum energy absorption percentage required by the first preset drop energy absorption condition) as the target packaging thickness for the packaging surface that meets the first preset drop energy absorption condition. In this way, using the target packaging thickness as the final packaging thickness for the packaging surface can minimize the size of the product packaging while still meeting the second drop energy absorption condition.

[0062] Step 103: Based on the preset drop height, a drop simulation test is performed on each third finite element model corresponding to the package surface at each preset contact area to determine a target contact area for the package surface that satisfies the second preset drop energy absorption condition. A third finite element model is constructed based on the second finite element model corresponding to the target package thickness and a preset contact area for the package surface.

[0063] In practice, due to the asymmetric structure of household appliances, the product packaging structure is also asymmetric. Therefore, when a drop simulation test is performed on the same packaging surface, packaging surfaces with the same thickness but different contact areas can absorb completely different impact energies. After the computer determines the target packaging thickness for the packaging surface, the packaging surface can be designed with different contact areas to conserve packaging material, while ensuring that the packaging surface meets the drop energy absorption condition (i.e., the second preset drop energy absorption condition). For the packaging surface of the product packaging, the computer can construct a third finite element model based on the second finite element model corresponding to the target packaging thickness and a preset contact area corresponding to the packaging surface. The second and third finite element models corresponding to the target packaging thickness have the same packaging thickness on the packaging surface, but different contact areas. The computer device can then perform drop simulation tests on each of the third finite element models corresponding to the packaging surface at each preset contact area, based on a preset drop height, to determine the target contact area for the packaging surface that meets the second preset drop energy absorption condition.

[0064] As an optional embodiment, the computer performs a drop simulation test on each third finite element model corresponding to the package surface at each preset contact area based on a preset drop height, and the processing steps for determining the target contact area of ​​the package surface that meets the second preset drop energy absorption condition are as follows:

[0065] Step 1: Based on a preset drop height, a drop simulation test is performed on each third finite element model corresponding to the packaging surface under each preset contact area to obtain a second energy absorption ratio corresponding to the packaging surface under each preset contact area.

[0066] In implementation, the computer performs a drop simulation test on each third finite element model corresponding to the packaging surface under each preset contact area based on the preset drop height, and outputs the energy absorption curve corresponding to the packaging surface under each preset contact area (such as Figure 5 As shown, Figure 5 For each preset contact area, the computer first determines the maximum energy absorption in the energy absorption curve corresponding to the packaging surface under the preset contact area (i.e. Figure 5 The computer then calculates the ratio of the maximum energy absorption to the impact energy experienced by the package surface as the second energy absorption ratio corresponding to the package surface at the preset contact area. Similarly, the computer device can determine the second energy absorption ratio corresponding to the package surface at each preset contact area. The impact energy experienced by the package surface = the total weight of the household appliance × the preset drop height × the gravity coefficient.

[0067] In step 2, among the preset contact areas where the second energy absorption ratio is greater than the second preset energy absorption ratio threshold, the minimum preset contact area is determined as the target contact area of ​​the packaging surface that meets the second preset drop energy absorption condition.

[0068] During implementation, after determining the corresponding second energy absorption percentages for the packaging surface at each preset contact area, the computer can further determine the minimum preset contact area among the preset contact areas where the second energy absorption percentage is greater than or equal to a second preset energy absorption percentage threshold (the second preset energy absorption percentage threshold is the minimum energy absorption percentage required by the second preset drop energy absorption condition) as the target contact area for the packaging surface that meets the second preset drop energy absorption condition. In this way, using the target contact area as the final contact area for the packaging surface can minimize packaging material usage while still meeting the second drop energy absorption condition.

[0069] Step 104: Slice the fourth finite element model of the product packaging and perform drop simulation tests on the fourth finite element model under various conditions based on a preset drop height to determine the packaging blocks to be optimized in the fourth finite element model that meet the preset drop optimization conditions. The fourth finite element model is constructed based on the first finite element model and the target packaging thickness and target contact area of ​​each packaging surface.

[0070] In practice, after the computer determines the target packaging thickness and target contact area of ​​each packaging surface, it can construct a fourth finite element model of the product packaging based on the first finite element model, the target packaging thickness and target contact area of ​​each packaging surface. Then, in order to further save packaging materials used for product packaging, the computer can cut the fourth finite element model of the product packaging into pieces. Figure 6 As shown, the fourth finite element model after segmentation consists of multiple packaging blocks. The computer then performs drop simulation tests on the fourth finite element model of the product packaging under various operating conditions based on a preset drop height, thereby identifying packaging blocks to be optimized within the fourth finite element model that meet the preset drop optimization criteria.

[0071] As an optional implementation, the computer performs drop simulation tests on the fourth finite element model of the product packaging under various working conditions based on a preset drop height, and the processing steps for determining the packaging blocks to be optimized in the fourth finite element model that meet the preset drop optimization conditions are as follows:

[0072] Step 1: Based on a preset drop height, perform a drop simulation test on the fourth finite element model of the product packaging under various working conditions to obtain the maximum energy absorption corresponding to each packaging block under various working conditions.

[0073] In the implementation, the computer performs a drop simulation test on the fourth finite element model of the product packaging under various working conditions based on the preset drop height, and outputs the energy absorption curve corresponding to each packaging block under various working conditions (such as Figure 7 The figure shows the energy absorption curve of each packaging block under one working condition. Figure 7 Each energy absorption curve in the equation corresponds to a packaging block. Each working condition includes 6 faces, 8 corners, and 12 flutes. For each packaging block, the computer determines the maximum energy absorption (i.e., the maximum energy absorption) of the energy absorption curve corresponding to each working condition. Figure 7 The maximum peak of the energy absorption curve).

[0074] Step 2: For each packaging block, if the maximum energy absorption corresponding to each maximum energy absorption of the packaging block under each working condition is less than a preset energy absorption threshold, the packaging block is determined as a packaging block to be optimized that meets the preset drop optimization conditions.

[0075] During implementation, after obtaining the maximum energy absorption values ​​corresponding to each packaging block under each operating condition, the computer may determine, for each packaging block, that the packaging block satisfies the preset drop optimization condition if any of the maximum energy absorption values ​​corresponding to the packaging block under each operating condition is less than a preset energy absorption threshold (the preset energy absorption threshold is the minimum energy absorption required by the preset drop optimization condition).

[0076] Step 105: Remove the packaging block to be optimized from the fourth finite element model to obtain a target finite element model of the product packaging, wherein the target finite element model is used for production of the product packaging.

[0077] In the implementation, after the computer determines the packaging blocks to be optimized, it further removes the packaging blocks to be optimized to obtain the target finite element model of the product packaging (such as Figure 8 As shown in the figure, the designed product packaging further saves packaging materials. Afterwards, production personnel can produce the product packaging based on the target finite element model.

[0078] It's important to note that once the computer equipment has generated the target finite element model of the product packaging, it can further address the specific structure of the household appliance by removing gaps in key product areas and reinforcing key stress-bearing areas. Furthermore, after production personnel have created the product packaging based on the target finite element model, they can perform drop tests to determine the packaging's reliability and impact resistance.

[0079] The present invention provides a method for determining product packaging. Based on drop simulation testing, a computer can design different packaging thicknesses and contact areas for different packaging surfaces of a packaged product and optimize packaging blocks with low energy absorption within the product packaging. This allows for rapid design of household appliance packaging, significantly shortening the packaging design cycle. Furthermore, while ensuring that the designed product packaging meets drop energy absorption requirements, the packaging size is minimized, saving packaging materials.
