[0017] The platform customization method specifically includes the following steps:

[0018] S1. Customer customization: The customer operates the client, which uses the http protocol to connect to the customization management service system data. After being authorized by the customer platform module, the bag customization module obtains customizable parts, custom materials, custom colors, and customized models and sticker image information from the database; the bag customization module uses the GLTFLoader module of three.js to load the model and the DRACOLoader to compress the model, import and parse the model; the client uploads the initial material and color of each component of the model according to the initial customization plan data returned by the server, and then displays the rendered 3D effect on the page through the WebGLRenderer module; anchor points are set on different components of the model. When the customer clicks on the page to switch materials, colors, or slides to rotate the model, three.js is used to control the color and material parameters in the model to display the effect of the customer's latest selected plan; when the customer completes the customization and clicks save, the client calls the camera module of three.js to take pictures of the front, back, left, and right sides of the customized model, and at the same time transmits the customization data and the final product picture to the cloud server via http. The bag customization module saves the customization data to the database;

[0019] S2. Order creation: Customers place orders for customized bags through the client. The client transmits the order data to the cloud server via a data connection. The order management module saves the order data to the database to complete the order creation.

[0020] S3. Payment Integration: After the order is created on the cloud server, the payment integration module connects to the payment platform API based on the customer's selected payment method and device, obtains payment parameters, and returns them to the client. The client then guides the customer to complete the payment based on the returned payment parameters. The payment platform API saves the payment data to the database through the payment integration module, and simultaneously notifies the customer of the payment completion via the client.

[0021] S4. Purchase order: After the customer completes payment, the cloud server adds the order to the purchase orders created that day and then pushes the order to the factory.

[0022] S5. Order Acceptance and Production Transformation: Manufacturers access the factory platform module on the cloud server through the factory app, view customization and order data, and accept orders. Based on the customization data, the orders are converted into factory production orders, and then put into production.

[0023] S6. Product delivery: After the manufacturer completes the production of customized bags and puts them into storage, the manufacturer sends the delivery information to the cloud server through the factory end, and the cloud server calls the express service provider's API interface to deliver the goods.

[0024] The client provides different entrances such as the Web terminal, Mobile terminal, Mini Program terminal, and App terminal according to the different operating devices of the customer. In the step S1, the customer connects to the customization management service system through the client to implement customization, which specifically includes the following steps:

[0025] T1. Model Presentation and Selection: The customer browses the customized bag guide page presented on the client and selects the specific model of bag to be customized. The client then proceeds to the customization operation page for the selected model of bag based on the selected model. The bag customization module renders the default 3D model of the selected model using default parameters and sends it to the client for viewing. The customer can then drag and rotate the 3D model to view the details of the customized bag from multiple angles.

[0026] T2. Solution Generation and Recommendation: The bag customization module uses AI-powered intelligent recommendations or free combinations to randomly match the various components of the bag product with different colors, materials, and custom text, generating a series of recommended solutions and displaying them on the client.

[0027] T3. Scheme selection and matching: The customer clicks on the customization operation page through the client to view the recommended schemes. When the user clicks on a recommended scheme, the bag customization module sends the corresponding parameters of the recommended scheme to the client and renders the model, presenting the recommended scheme to the customer for viewing, so that the customer can browse and select the design scheme easily;

[0028] T4. Customers can click to view more recommended solutions generated by the server through AI intelligence or free combination. The server will use a series of algorithms based on the user's operating and browsing habits to prioritize the combinations that the user is most likely to be interested in.

[0029] T5. Based on the client's actions on the client's customization page, component selection, or specific component operations on the 3D model, the client obtains the parameters of the customizable components for the current model of customized luggage from the cloud server and presents them to the client, allowing the client to view the visual effects of the 3D rendered model under various parameters in real time.

[0030] T6. After customers have selected specific custom luggage parts, they can choose the corresponding fabric and color parameters. The client will render the 3D model in real time based on the different parameters of the parts and fabrics selected by the user, presenting the visual effects of the parameters to customers more intuitively; thus, customers can combine various fabrics and colors according to their own aesthetic preferences.

[0031] T7. Saving and Uploading Designs: After the customer completes customization, the cloud server will detect the customer's login status by issuing instructions on the client. If the customer is not logged in, the client will prompt the customer to log in. If the customer is logged in, the client will generate a new design based on the customer's selected parameters, such as fabrics and colors, and save it. The design will also be uploaded to the cloud server's database and associated with the customer's account information. The customer can view the customization plan and its details on the client at any time, or download it from the cloud server by logging in.

[0032] T8. Confirm and Compare Designs: The customer further verifies the customization plan through the client. After confirming the customization parameters and 3D view are correct, they can choose to add the customization plan directly to the shopping cart. Here, during further verification, the customer can review the customization plan again and view other previously saved designs for the same model of customized bag. They can switch to other designs and compare them, allowing them to choose between different preferences.

[0033] Due to the complex process of making packages, the factory cannot directly identify which materials to take out after receiving the customer's customized information. It is necessary to separate the customized parts and non-customized parts one by one according to the components. The customization management service system also includes a processing flow module. The step S5 specifically includes the following steps:

[0034] The manufacturer connects to the factory platform module through the factory end in advance, sets the parts inventory and processing flow information and stores them in the database; after the manufacturer accepts the order at the factory end, the processing flow module matches the parts required for the customized data from the database with the factory inventory according to the manufacturer's settings, automatically generates a Bom table, retrieves the matching parts and processes, and uses a code program to lay them out in order on an Excel document to generate a manufacturing order. The manufacturing order includes three documents: a material list, a processing list, and a quality inspection list. Here, the processing flow module matches the customer's customized information on the color and material of the luggage with the color and material of the corresponding parts in the manufacturer's inventory. For example, if the customer chooses aurora green shoulder strap webbing on the client side, the processing flow module matches the corresponding factory to form a material list including 381C fluorescent green shoulder strap ears, main bag zipper, back zipper, shoulder strap, etc. This helps manufacturers better invest in production.

[0035] For the generated manufacturing orders, especially when the order volume is large, manually downloading and printing them one by one is very time-consuming. Furthermore, the factory-side APP includes a monitoring and printing module, which communicates with the cloud server via websocket to automatically print the manufacturing order upon receipt. Specifically, the steps include:

[0036] The cloud server sends a "new order to be printed" command to the monitoring and printing module on the factory side. The monitoring and printing module then downloads the Excel file of the order manufacturing order through HTTP request.

[0037] After the download is complete, the monitoring print module calls the print module of Windows PowerShell to select a printer to print out the manufacturing order.

[0038] Furthermore, the factory-side APP also includes a code scanning and recognition module, the customized management service system includes a courier management module, and the monitoring and printing module also has the function of automatically printing a delivery express delivery note. The manufacturing note is provided with a barcode matching the customer's delivery information, specifically including the following steps:

[0039] When the manufacturer completes the production of customized luggage, the barcode on the manufacturing order is identified by a barcode scanner, and the barcode recognition module sends the identified matching customer shipping information to the cloud server;

[0040] The express management module of the cloud server stores the order in the database and calls the express service provider's API interface at the same time. It sends the customer's delivery information and the manufacturer's delivery information from the database to the express service provider's server to complete the express delivery request.

[0041] After the courier service provider server receives the order, the courier management module sends the information to the factory-side APP;

[0042] The monitoring and printing module then monitors the express order information and calls the Windows PowerShell printing module to print out the express order. In this way, the express service provider can directly pick up the package, eliminating the intermediate steps such as information entry, thereby achieving fast delivery.

[0043] To achieve pull production, ensure that production is carried out at the right time and in the right volume, prevent the factory from holding high levels of inventory to meet delivery needs, and minimize inventory waste, the customized management service system also includes a PMC automatic procurement and replenishment module to monitor the usage and inventory status of various materials:

[0044] Through big data analysis of user-customized information in the recent time period, the PMC automatic procurement and replenishment module provides recommended safety stocks for all parts and monitors in real time which materials are below the set safety stock. For those below the safety stock, purchase orders and internal processing orders are automatically generated, and the manufacturer can replenish the inventory to the set inventory level according to the documents and update the inventory information.

[0045] The customized management service system also includes a profit analysis module, which automatically calculates the cost and profit of each transaction through an algorithm based on the working hours entered by the manufacturer every day and the manufacturing and labor costs entered by the finance department, and then retrieves the purchase order, ingredient list, and manufacturing order data generated by the system in the database.

[0046] The customization management service system is equipped with an AR generation module. When the customer completes the customization of luggage and chooses to settle the bill, the AR gift card can be customized through the settlement page presented by the client. The AR generation module generates AR data based on the text, picture, style and other contents of the gift card set by the customer and stores it in the database; the AR gift card uses QR code technology or NFC chip technology. When the code is scanned or the built-in information of the NFC chip is obtained through a smartphone, people can view the AR data corresponding to the gift card through an AR perspective, thereby giving the customized luggage a stronger sense of technology and experience.

[0047] The customized bag is equipped with a washing mark QR code inside. When the user receives the customized bag product, in addition to conducting online consultation through the client, the user can also scan the washing mark QR code inside the customized bag through a smart electronic device, call up the after-sales feedback page to make product suggestions, and the cloud service end will handle the follow-up matters of such feedback through regular maintenance based on the user's feedback information; if the customer participates in AR gift card customization, he or she can also view the AR gift card effect of the bag in real time by scanning the QR code on the bag body or reading the NFC chip to obtain a better user experience.

[0048] The customization management service system features a production capacity information module. After payment is completed, the order's custom bag parameters and 3D images are sent to the factory. The module then uses a production capacity information algorithm to schedule the order, calculate the estimated delivery time for the order, and synchronize it with the client. Customers can also view real-time order information on the client, including production progress, shipping progress, and logistics flow details for the customized bags.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
