Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machining, in particular to a tire sidewall text design generation method and device, electronic equipment and medium. BACKGROUND

[0002] In the current tire mold manufacturing industry, the design and program generation of tire sidewall text and patterns mainly rely on special text design systems. Such systems usually run as plug-ins or units of specific three-dimensional computer-aided design (CAD) software, and their function depth is bound to the host three-dimensional platform. During design, designers need to rely on their manual experience and operation: the designer needs to manually position each text block on the three-dimensional model, set its content, font, size, arrangement method and other properties one by one, and repeatedly adjust to adapt to the complex curved surface of the tire sidewall. This design process, which highly depends on manual judgment and manual adjustment, not only consumes time and effort, but also makes it difficult to ensure the consistency of design standards and quality between different designers or different batches, resulting in low design efficiency and high cost.

[0009] Obtain a historical design scheme bound to the similar historical expected pattern from the text design scheme storage library; based on the text arrangement parameters, adapt the text block parameters in the historical design scheme to generate a first design scheme matching the current tire size;

[0010] Based on the tire side curve information, the first design scheme is optimized and adjusted for manufacturing process to generate a manufacturable scheme;

[0011] The manufacturable scheme is converted into a numerical control machining program and transmitted to a machining device for execution to form a text pattern design consistent with the expected pattern on the tire side.

[0044] In a third aspect, the embodiments of the present application further provide an electronic device, comprising a memory and a processor, which are communicatively connected with each other, and the memory stores computer instructions, and the processor executes the computer instructions to perform the tire sidewall text design generation method of the first aspect or any of the corresponding embodiments thereof.

[0045] In a fourth aspect, the present application provides a computer readable storage medium having computer instructions stored thereon, the computer instructions being used to cause a computer to execute the tire sidewall text design generation method of the first aspect or any of the corresponding embodiments thereof.

[0046] In addition, the present application provides a computer program product comprising computer instructions for causing a computer to execute the tire sidewall text design generation method of the first aspect or any of the corresponding embodiments thereof.

[0047] The tire sidewall text design generation method, device, electronic equipment and medium provided by the present application mainly have the following beneficial effects:

[0048] 1. The traditional method completely relies on manual operation of designers in three-dimensional software, which is time-consuming and labor-intensive and requires high-skilled personnel. The present application can automatically match, retrieve and reuse historical mature solutions from the knowledge base, and quickly match the design scheme to the new tire size by using parameterization automatic adaptation technology, realizing the paradigm shift from "manual creative design" to "intelligent retrieval and automatic adaptation". This avoids a lot of repetitive manual labor, liberates designers from tedious geometric adjustments, significantly shortens the design cycle, reduces the dependence on the professional experience of the operator, and thus greatly reduces the labor and time costs.

[0049] 2. The traditional manual design is easily affected by the personal experience and state of the designer, resulting in inconsistent design standards. The present application establishes a standardized "text design scheme storage library", and fixes the historical successful schemes and their accurate parameters as enterprise knowledge assets. By using the retrieval and reuse mechanism, the new design automatically inherits the high-quality layout and parameters verified by production, fundamentally ensuring the high consistency and standardization of the design quality output by different batches and different personnel, which is beneficial to the unity of brand image and the stability of product quality.

[0050] 3. In the traditional process, design and processing programming are disconnected, and a large number of manufacturing parameters need to be manually set again, which is prone to errors and low efficiency. The present application performs automatic optimization adjustment (such as surface normal compensation, visual distortion correction, and interference checking) based on the accurate sidewall surface information before generating the final scheme, which prepositions the manufacturing constraints and process knowledge in the design stage. This makes the "manufacturable scheme" naturally meet the processing requirements. Combined with the automatic code generation in the last step, it realizes one-key and seamless conversion from the optimized design scheme to the numerical control program, eliminates the information distortion and human error risk in the traditional multi-link conversion, ensures the accurate realization of the design intention on the final product, and improves the first-piece success rate and overall production efficiency.

[0051] 4. Enhancing flexibility, considering individual needs and rapid response. The method is not a rigid template application. Intelligent retrieval and parameterized adaptation enable the system to quickly respond to customer demand for mature styles and adapt to different specifications by modifying parameters. At the same time, the system also provides a path for the design of new styles (such as through other branches or template libraries), ensuring efficiency and standardization while considering market demand for tire appearance individualization and design diversification, enhancing the enterprise's market response speed and competitiveness.

[0052] In summary, the present application effectively solves the core pain points of low efficiency, inconsistent quality, high skill dependence, design and manufacturing disconnection, etc. in traditional tire sidewall text design by constructing an intelligent design retrieval, reuse, adaptation and manufacturing optimization integrated process, providing an efficient and reliable technical solution for the digitalization, automation and intelligent upgrading of the tire industry.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0067] It can be understood that, before using the technical solutions disclosed in the embodiments of the present application, the type, use range, use scenario, and the like of personal information involved in the present application should be informed to the user and the authorization of the user should be obtained in a proper manner according to relevant laws and regulations.

[0068] The terms "first", "second", and the like are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0069] The embodiments of the present application provide a tire sidewall text design generation method, which realizes full-process management from text design to processing program generation through an integrated and intelligent system. Through the tool, manual intervention is reduced, manual operation is reduced, and the time consumption of the whole process is reduced.

[0070] As an optional application scenario of the embodiments of the present application, the method of the embodiments of the present application can be applied to a character design system, such as a tire mold arc character design system. Optionally, the system can be a terminal device or a network device. For the terminal device, it can be specifically a notebook computer, or a desktop computer, such as a PC device, etc. For the server, the server can be a standalone physical server, or a server cluster or a distributed system, or a cloud server providing cloud services. The present embodiment does not limit this.

[0071] In addition, other devices such as processing devices, such as machine tools, etc. can also be included in the system. The processing device is used to receive the numerical control processing program from the terminal device and perform processing procedures and the like.

[0072] According to the embodiments of the present application, a tire sidewall character design generation method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0073] In the present embodiment, a tire sidewall character design generation method is provided, which can be applied to the character design system described above, Figure 1 is a flowchart of a tire sidewall character design generation method according to an embodiment of the present application, as Figure 1 shown, the flow includes the following steps:

[0074] S1: Obtain a tire design electronic drawing to be processed, and extract sidewall curve information and character arrangement parameters from the tire design electronic drawing.

[0075] The tire design electronic drawing includes the tire sidewall design desired by the user. The tire design electronic drawing is used to describe the key parameters of the three-dimensional geometry of the tire sidewall (i.e. the tire side surface). It is not a complete curved surface model, but a set of reference data that can accurately position the character arrangement area and calculate the curved surface deformation.

[0076] Optionally, the tire design electronic drawing can be a two-dimensional electronic drawing of the tire design provided by the customer, such as a vector format of DWG, DXF, etc.

[0077] Sidewall curve: a curve representing the actual profile of the sidewall (which can be a straight line, a circular arc, or a spline curve). The curvature of this curve is the key to calculating the character compression ratio later. The function of the sidewall curve is to provide a precise, three-dimensional "canvas" framework for subsequent character layout. The radial position, circumferential arrangement, and visual deformation adjustment for the curved surface of all characters are calculated based on this information. For example, as Figure 2The figure shown is a schematic view of a tire sidewall curve.

[0078] Text arrangement parameters are the geometric and attribute parameters of the existing text elements identified from the customer-provided electronic drawing. They represent the customer's preliminary design intent and serve as a reference for the system's intelligent adaptation or correction. Specific content usually includes:

[0079] Content: The text string itself (e.g., "SAFETY WARNING", "315 / 80R22.5").

[0080] Position: Specifically includes radial position and circumferential position. Radial position: the radius of the text center line relative to the tire center axis. Circumferential position: the angle (usually in degrees) at which the text starting point or center point is located.

[0081] Geometric attributes: such as font height: the nominal height of the text. Font width / aspect ratio: the width or width-height ratio of the text. Font type: the font type of the text (may be represented by a wireframe outline).

[0082] Arrangement: linear arrangement, circular arrangement, or other arrangements.

[0083] The role of text arrangement parameters is to understand the customer's initial idea, which is used to compare, integrate or correct with standard schemes in the knowledge base in subsequent steps, to ensure that the final scheme does not deviate from the customer's basic layout intent.

[0084] One specific implementation of step S1 is: based on the tire design electronic drawing, perform graph element classification and key set feature extraction on the tire design electronic drawing, including locating the "water channel" and "scuffing line" in the two-dimensional coordinates of the drawing through algorithms (such as finding the endpoints of a specific length of horizontal line, calculating the tangent points of adjacent curves, etc.), and then converting these coordinates to polar coordinates (radius R) with the tire center as the origin according to the drawing scale and tire center reference.

[0085] Iterate through all text objects and directly read their "content" attribute. Determine its two-dimensional coordinates by calculating the geometric center of the text bounding rectangle or bounding box, and also convert them to radial position (R) and circumferential angle (A) relative to the tire center. At the same time, measure the dimensions of the text bounding box to obtain the font height and font width.

[0086] After step S1 is completed, a structured data object has been generated in the system, containing all key geometric and text information "extracted" from the drawing, providing accurate input for the subsequent intelligent matching and generation process.

[0087] S2: Extract the desired pattern representing the layout style of text and decorative elements from the tire design electronic drawing.

[0088] Specifically, the steps include:

[0089] Step 1: Style Abstraction and Standardization. The system reads the vector electronic drawing provided by the client, automatically strips away all specific text content (such as brand and model), retains only the outer frame of the text blocks, the geometric outline of decorative elements, and their precise relative positions, sizes, and topological relationships, and normalizes the entire graphic to a standard coordinate system and size, generating a pure, content-free standard vector graphic.

[0090] Step 2: Image Search and Scheme Association. The system calculates a lightweight feature fingerprint (such as an image hash or layout grid code) for the standard drawing. Then, using this fingerprint as a query criterion, it performs a rapid similarity search in a pre-stored knowledge base containing a large number of historical schemes and their corresponding standard drawings. Upon successful matching, the system extracts the "historical design scheme" bound to the historical drawing, which contains complete parametric design rules, thus completing the intelligent association from visual style to reusable design template.

[0091] S3: Using the desired image as the search criteria, perform a matching search in the preset text design scheme repository.

[0092] The text design scheme repository stores multiple historical design schemes and their associated historical expected patterns.

[0093] The implementation of the S3 step is essentially an intelligent retrieval and retrieval process based on a "style-scheme" related knowledge base. Its operation relies on a pre-built, structured "text design scheme repository," and the establishment of this text design scheme repository and the retrieval and retrieval of S3 form a complete closed loop.

[0094] The specific implementation process includes:

[0095] First, the construction and updating of the text design scheme repository is an ongoing background process to ensure the repository is rich and effective.

[0096] Whenever a design scheme (such as Pro-XXX12R22.5) is completed and saved in the system, the system automatically performs the following operations: Extract Style: Based on the scheme's parameters, automatically render and generate a standardized vector "historical expected pattern" (i.e., a layout framework diagram with specific content removed). Extract Identifiers: Automatically extract the scheme name and other identifiers as unique identifiers and keywords. Parameter Packaging: Associate and package the driving parameters of all text blocks in the scheme (such as content C, radial position R1, circumferential position A1, character height, etc.) with the historical expected pattern and scheme identifiers, forming a "pattern set". Dynamic Updates: The repository supports dynamic overwrite updates. When an existing scheme is modified and re-saved, the new version will automatically overwrite the old version, ensuring the timeliness of knowledge within the repository.

[0097] Secondly, intelligent image-based retrieval (dynamic execution of S3) is employed. Specifically, the system receives the current "expected pattern" representing the customer's needs, output from step S2. This "expected pattern" is then quickly compared in terms of feature similarity to all "historical expected patterns" in the text design scheme repository. This is typically achieved by calculating image hashes, layout feature vectors, etc., aiming to find one or more historical patterns with the most similar style and layout.

[0098] Once a similar historical pattern is matched, the system directly locates and extracts the corresponding complete parametric historical design scheme (including the driving parameter logic of all text blocks) through its bound "pattern set".

[0099] Finally, the output of step S3 is no longer a simple image, but one or more structured, parameter-modifiable "historical design scheme" objects that can be directly used to drive the design system. For example, it extracts not only a text block of "MADEIN xxxx", but also a set of parameterized definition rules containing its content (C) and relative to the original baseline (R1, A1), providing precise input information for the intelligent adaptation in the subsequent step S4.

[0100] S4: Determine whether there is a historical expected pattern similar to the expected pattern in the text design scheme repository.

[0101] If a historical desired pattern similar to the desired pattern exists in the text design scheme repository, then proceed to step S41.

[0102] Step S41 includes: obtaining historical design schemes bound to similar historical expected patterns from the text design scheme repository; adapting the text block parameters in the historical design schemes based on the text layout parameters to generate a first design scheme that matches the current tire size.

[0103] Specifically, one implementation method for adapting text block parameters in historical design schemes is as follows: adaptation is performed based on the following conditions or criteria ① to ⑤:

[0104] ① Extract all module text from historical design schemes that are bound to similar historical expected patterns. Extract the reference position points from their layout parameters, such as... Figure 7c As shown, for example, the reference point RA is reset to: RA + AA - BA based on the difference between the waterproof ditch position AA and the anti-friction line position BA.

[0105] ② Extract all module text with variable radial parameter "TRUE" from historical design schemes bound to similar historical expected patterns, extract the reference position point RA2 from its updated layout parameters, compensate according to the cavity layout width, and reset the reference point to: RA2+AW-BW; where AW is the length of the cavity layout area and BW is the cavity layout area.

[0106] ③ Determine the relationship between the arrangement position of all model text and AB. If the text arrangement position is outside the cavity arrangement area and approximately at point AB in the arrangement area, then readjust its reference position as follows: extract the reference position point RA2 in its updated arrangement parameters, compensate according to the anti-scratch line position point BB, and reset the reference point to: RA2-AB+BB.

[0107] ④ Extract all module patterns with the engraving parameter "TRUE" in the design scheme, extract their layout parameter height HA, and judge according to the cavity layout width and principle. If processing is required, set the layout parameter height to: RA2×AW / BW.

[0108] Extract the corresponding template file from the template library based on the style and import it into the 3D environment. Extract the reference point BA for the waterproof trench, the reference point BB for the anti-scuff line, and the cavity layout area BW from the template.

[0109] Repeat the adaptation steps ①-④ in the intelligent recommendation design scheme;

[0110] ⑤ Modify the generated design scheme based on the design data. Delete redundant module text, add missing module text, and update incorrect layout parameters.

[0111] The "first design scheme" output in this step is a parametric, drivable digital design scheme with preliminary geometric adaptation for the current tire size. It is not the final product, but rather the first high-quality draft generated by the system along the "intelligent reuse" path. The first design scheme is a structured dataset that precisely records the content of each text block, as well as all driving parameters such as position and size recalculated based on the new tire baseline.

[0112] In this step, the retrieved historical design scheme serves as the "design logic template," and the current tire sidewall surface parameters extracted from the electronic drawing serve as the "new size reference." Through proportional conversion and geometric mapping, the coordinates and dimensions of all elements in the historical design scheme are automatically converted from the old reference system and adapted to the new tire size. This process reproduces mature design styles and layouts while ensuring precise matching with the new entity, achieving a leap from "experience retrieval" to "intelligent creation."

[0113] Furthermore, the "first design scheme" plays a crucial role in subsequent processes, bridging the gap between earlier and later stages. It completely liberates designers from tedious and repetitive manual calculations and adjustments, greatly improving design efficiency and saving costs while ensuring consistent design quality.

[0114] In addition, such as Figure 1 As shown, the above steps also include:

[0115] S5: Based on the sidewall surface information, the first design scheme is optimized and adjusted for manufacturing process to generate a manufacturable scheme.

[0116] The purpose of this step is to check the compliance of the spelling laws and regulations, the correctness of data conversion, and the correspondence of specifications and values ​​in the first design scheme mentioned above, in conjunction with the tire sidewall surface information.

[0117] Furthermore, the rules of laws and regulations, the rules for converting verification data, and the rules for correspondence can be set in advance as needed. The comparison process can be carried out by comparing each item / character by character, or by using other comparison and verification methods. This embodiment does not impose any restrictions on this.

[0118] The "manufacturable solution" can be understood as the final output of step S5, which is a high-fidelity 3D digital instruction set that is fully prepared for CNC machining and can directly drive production. It represents the final state transition from "conceptual design" to "production ready".

[0119] S6: Convert the manufacturable scheme into a CNC machining program and transmit it to the machining equipment for execution to form a text pattern design on the tire sidewall that matches the desired pattern.

[0120] Step S6 is an automated post-processing and instruction generation process. The system takes the "manufacturable solution" as input. Its built-in code logic unit (post-processor) first automatically performs toolpath planning, calculating a non-interference, efficient tool center motion trajectory based on the 3D contour, depth, and normal information of each text and pattern in the solution. Subsequently, the logic unit combines the trajectory data with preset process parameters (such as spindle speed, feed rate, and tool change commands), automatically compiling and generating a directly executable G-code file, i.e., an NC (Numerical Control) program, according to the specific language of the target CNC machine tool control system. Finally, the system transmits this program file to the tire mold engraving machine or laser marking machine via a local area network or mobile storage medium. The equipment receives and executes the program, thereby precisely machining text and patterns that perfectly match the "desired pattern" onto the tire sidewall.

[0121] An NC program (numerical control machining program) is a text file written in a specific format and code, containing a series of instructions for precisely and automatically controlling the operation of CNC machine tools (such as engraving machines, milling machines, and lathes).

[0122] Specifically, one possible implementation of step S6 includes: based on the sidewall surface information, performing one or more of the following compensatory adjustments on the first design scheme: surface normal compensation, visual distortion correction, and adjustment of processability and interference verification; editing the adjusted design scheme according to the final design requirements, and setting the final shape and layout parameters of the text and patterns to generate a manufacturable scheme.

[0123] The tire sidewall text design generation method provided in this embodiment achieves end-to-end automation from customer electronic drawings to CNC machining programs by constructing and intelligently retrieving a historical design scheme repository, combined with automated parameter adaptation and manufacturing optimization processes. This method offers the following advantages:

[0124] First, it significantly improves design efficiency and reduces labor costs and reliance on skills.

[0125] Traditional methods rely entirely on designers manually operating 3D software, which is time-consuming, labor-intensive, and requires highly skilled personnel. This invention, through steps S3 and S4, automatically and intelligently matches, retrieves, and reuses historically mature solutions from a knowledge base. Furthermore, utilizing the parametric automatic adaptation technology in step S41, it quickly adapts the design solution to the new tire size, achieving a paradigm shift from "manual creative design" to "intelligent retrieval and automatic adaptation." This avoids a large amount of repetitive manual labor, freeing designers from tedious geometric adjustments, significantly shortening the design cycle, reducing reliance on the professional experience of operators, and thus substantially reducing labor and time costs.

[0126] Second, ensure consistent design quality and achieve knowledge accumulation and standardization.

[0127] Traditional manual design is easily influenced by the designer's personal experience and state of mind, leading to inconsistent design standards. This invention, through the standardized "text design scheme repository" established in step S3, solidifies historical successful schemes and their precise parameters as corporate knowledge assets. The retrieval and reuse mechanism in step S4 ensures that new designs automatically inherit high-quality layouts and parameters validated in production, fundamentally guaranteeing a high degree of consistency and standardization in design quality across different batches and from different personnel.

[0128] Third, break down design and manufacturing barriers to achieve precise and efficient production conversion.

[0129] In traditional processes, design and manufacturing programming are disconnected, requiring manual resetting of numerous manufacturing parameters, which is error-prone and inefficient. This invention, through step S5, performs automatic optimization and adjustments based on precise tire sidewall surface information (such as surface normal compensation, visual distortion correction, and interference checks) before generating the final design, placing manufacturing constraints and process knowledge at the design stage. This ensures that the generated "manufacturable design" naturally meets processing requirements. Combined with the automatic code generation in step S6, a one-click, seamless conversion from the optimized design to the CNC program is achieved, eliminating information distortion and human error risks associated with traditional multi-stage conversions. This ensures the accurate realization of design intent in the final product, improving first-piece success rate and overall production efficiency.

[0130] Fourth, enhance flexibility, balancing individual needs with rapid response.

[0131] The intelligent retrieval in step S4 and the parameterized adaptation in step S41 of this method enable the system to quickly respond to customer demands for mature styles and adapt to different tire specifications by modifying parameters. Simultaneously, the system provides pathways for designing entirely new styles (such as through other branches or template libraries), ensuring efficiency and standardization while also catering to market demands for personalized tire appearance and diverse designs, thereby enhancing the company's market responsiveness and competitiveness.

[0132] In summary, the method provided in this embodiment effectively solves the core pain points of traditional tire sidewall text design, such as low efficiency, inconsistent quality, high skill dependence, and disconnect between design and manufacturing, by constructing an intelligent integrated process of design retrieval, reuse, adaptation, and manufacturing optimization. It provides an efficient and reliable technical solution for realizing the digital, automated, and intelligent upgrade of the tire industry.

[0133] Furthermore, in one possible implementation of the above embodiments, such as Figure 3 As shown, step S1: Extracting tire sidewall surface information from the tire design electronic drawing, specifically including:

[0134] S1-1: Obtain all geometric elements in the above tire design electronic drawing, extract solid lines from the geometric elements and sort them.

[0135] S1-2: Filter the sorted solid lines, delete invalid solid lines, identify and separate the two-end curves and the middle curve from the remaining graphic elements after filtering, and remove invalid two-end curves based on the relative position of their lowest points, retaining the characteristic curves that represent the main surface of the tire sidewall.

[0136] S1-3: Calculate the connection points of adjacent curve segments in the characteristic curve, and identify non-tangent connection points as key feature points, which are at least part of the tire sidewall surface information.

[0137] The specific implementation process of the above steps includes: picking up all the graphic elements in the electronic drawing of the tire design, extracting the solid lines from all the graphic elements, and sorting them according to certain rules (such as from left to right, from bottom to top). Then, clean up the irrelevant graphic elements. For example, delete the straight lines at the bottom (usually representing the ground line) and the highest point on the rightmost side. Starting from the left, delete all vertical lines with a length > 2 mm (which may be section lines or auxiliary lines). All the remaining graphic elements after the deletion operation are mainly curves and short straight lines that describe the shape of the tire sidewall.

[0138] Identify the effective curve segments. Among the remaining graphic elements, find the lowest points P2 and P3 of the two end curves and the lowest point P1 of the middle curve. Compare the heights: if the heights of P2 and P3 < the height of P1, then delete the two end curve parts where P2 and P3 are located. The purpose of doing this is to retain the main bulging part of the lower tire sidewall surface.

[0139] In addition, it also includes: identifying the water groove and the anti - rubbing line. Specifically, calculate whether two adjacent curves are tangent, and calculate the non - tangent points. Then, the inner side is the position of the water groove, and the outer side is the position of the anti - rubbing line. Finally, according to the position of the water groove, calculate its radius R0. According to the position of the anti - rubbing line, calculate its radius R1. Furthermore, calculate the width of the arrangement area W = R1 - R0.

[0140] In this embodiment, the functions or beneficial effects of the tire sidewall surface information include:

[0141] 1. Locate the arrangement area. Through the positions of the water groove and the anti - rubbing line on the tire sidewall surface, obtain the radius and width of the font arrangement, which are used as the basis for adjusting each text block when generating a recommended design plan later.

[0142] 2. The tire sidewall surface is the basis for determining the text compression ratio during program generation. Through the tire sidewall curve, obtain the ratio of the height of the curved - surface text to the height of the flat - surface text to determine the text compression ratio.

[0143] Furthermore, in another possible implementation manner of the above - mentioned embodiment, as Figure 4 shown, the above step S41: adapt the parameter of the text block in the historical design plan to generate a first design plan matching the current tire size, which specifically includes:

[0144] S41 - 1: Obtain the historical reference parameters on which the historical design plan is based during the original design.

[0145] S41 - 2: Obtain the current reference parameters extracted from the electronic drawing of the tire design.

[0146] Among them, both the historical reference parameters and the current reference parameters at least include the position of the water groove, the position of the anti - rubbing line, and the width of the arrangement area, etc.

[0147] S41-3: Based on the proportional relationship between historical reference parameters and current reference parameters, recalculate and map the position and size parameters of all text blocks in the historical design scheme, and generate the first design scheme.

[0148] Specifically, one possible implementation is as follows: In step S41-1, the system extracts the original design baseline parameters from the metadata of the matched historical design scheme "Pro-XX12R22.5", denoted as: historical waterproof groove position BA = 280mm, historical scuff line position BB = 320mm, and historical layout area width BW = BB - BA = 40mm. These parameters define the size framework of the "standard tire" on which the historical scheme was originally based. Next, in step S41-2, the system calls the sidewall surface information extracted from the current customer electronic drawing (such as a tire with a specification of 13R22.5) to obtain the current baseline parameters: assuming the current waterproof groove position AA = 300mm, the current scuff line position AB = 345mm, and the current layout area width AW = AB - AA = 45mm. By comparison, the system determines that the layout area of ​​the current tire is 5mm wider than the prototype of the historical scheme.

[0149] Secondly, the parametric mapping and first design scheme generation process is executed. Specifically, based on the above differences, step S41-3 initiates intelligent mapping. The system iterates through each text block in the historical scheme. For example, the original radial position parameter of the "MADE IN CHxxx" text block is R1_original = 300mm. The system does not directly copy this value, but recalculates it according to the reference ratio: First, it calculates the relative ratio of this position in the historical width BW (R1_original - BA) / BW = (300-280) / 40 = 0.5, which means that the text was originally located in the center of the layout area. Then, this ratio is mapped to the current width AW, and the new radial position R1_new = AA + 0.5 × AW = 300 + 0.5 × 45 = 322.5mm is calculated.

[0150] Similarly, the position and size (such as character height) of all text blocks are automatically calculated according to this logic of "relative proportion remains unchanged", thereby generating a "first design scheme" with a layout style that is completely consistent with the historical scheme, but all geometric parameters have been precisely adapted to the current tire size.

[0151] This implementation transforms the complex design adaptation process from one reliant on human experience and manual calculations into a fully automated, parameterized, and precise mathematical mapping. By accurately extracting and comparing old and new baseline parameters, the system can recalculate the position and size of each text block in the historical design with millimeter-level precision, based on strict proportional relationships. This completely eliminates errors and inconsistencies that may arise from manual conversion, ensuring the geometric correctness of the reused design on the new tire surface. It completes adaptation work that previously required hours or even longer for experienced designers, achieving a dual improvement in efficiency and accuracy.

[0152] Optionally, in this embodiment, a method for constructing a preset text design scheme repository is also provided. This method can be executed before the aforementioned step S4. Specifically, as follows: Figure 5 As shown, the methods of this text design scheme repository include:

[0153] S501: When any design scheme is completed, extract the file name or preset identifier of the design scheme as its unique identifier.

[0154] When a designer completes a tire sidewall text design scheme in the system (for example, designing a complete layout including brand, specifications, and certification marks for a specific tire model) and performs a "save" operation, the system automatically triggers the archiving process. The system first reads the file attributes of the scheme and extracts its pre-defined, business-meaning unique identifier. For example, if the scheme file is named "ProLine_Highway_12R22.5_V2.ltd", the system will extract "ProLine_Highway_12R22.5_V2" as the unique identifier for that scheme. This identifier will serve as the core index code for that scheme throughout the entire repository, used for subsequent classification, rapid retrieval, and version management.

[0155] S502: Generate a standardized vector graphic that completely corresponds to the layout of text and decorative elements in the design scheme, and use the standardized vector graphic as the historical expected graphic associated with the design scheme.

[0156] The system takes the newly completed design as input and automatically performs a "style rendering and abstraction" process. Based on the design's driving parameters, it generates a standardized vector graphic in the background that perfectly matches the visual layout of the design. During this process, all specific text content (such as "MMMM") is replaced with generic placeholders (such as "[Brand]"), and decorative elements retain their geometric outlines but have uniform line types and colors. The final result is a vector file that removes specific content and retains only the pure geometric layout relationships; this file is defined as the "historical expected pattern" bound to the design. This pattern is the key feature for subsequent "image-based" style matching.

[0157] S503: Associate and store the parameterized driving parameters of all text blocks in the design scheme with unique identifiers and historical expected patterns.

[0158] The driving parameters include at least one or more of the following: text content, radial position, circumferential position, character height, and character width ratio.

[0159] The system deeply analyzes the design scheme, extracting and structuring all its driveable and modifiable parameters. This includes: driving parameters for each text block (such as brand block, specification block, and place of origin block): at least including text content, radial position R, circumferential angle A, character height H, character width ratio W_Ratio, font type, etc.; geometric parameters of decorative patterns; and baseline parameters for the overall scheme: such as the location of the waterproof trench BA, the location of the anti-abrasion line BB, and the width of the layout area BW used in the design. Subsequently, the system establishes a strong correlation: binding the "historical expected pattern" generated in the previous step, the "complete set of driving parameters" extracted in this step, and the "unique identifier" obtained in the first step to form a complete data package.

[0160] S504: Store the unique identifier, associated driving parameters, and the historical expected pattern as a searchable pattern set in the text design scheme repository.

[0161] The system treats the complete data package as an indivisible "pattern set" and prepares to store it in the text design scheme repository. Before storage, the system will automatically search the repository for identical or highly similar records based on the characteristic hash values ​​of the "unique identifier" and "historical expected patterns".

[0162] If it's a new solution: the system allocates a complete storage path and index to the "drawing set" and stores it as new knowledge in the database, enriching the diversity of the knowledge base. If it's a solution update (i.e., a record with the same identifier already exists in the database): the system automatically overwrites the old record with the new "drawing set". This means that new driving parameters and new historical expected drawings will replace the old version, while retaining the same unique identifier. This achieves iterative updates and version control of design knowledge, ensuring that the database always stores the latest and most accurate design standards.

[0163] Optionally, in this embodiment, the repository construction method is deeply integrated with the system's permission management module. For example, only users with "customer manager" or "administrator" permissions will have their save or overwrite operations ultimately executed, while "ordinary users'" saves may only generate a local copy or require submission for review, thus ensuring the accuracy and security of the core knowledge base. Through this automated and structured construction and update process, enterprises can transform their continuously accumulated design experience into searchable, callable, and iterable digital assets, providing a powerful core driving force for the entire intelligent design process.

[0164] Furthermore, in the above embodiments, the judgment step of step S4 further includes: if there is no historical expected pattern similar to the expected pattern in the text design scheme repository, then step S42 is executed. Figure 6 As shown, step S42 includes:

[0165] S42-1: Read the text template database.

[0166] The text template database stores multiple general text templates corresponding to specific layout styles. Each general text template contains parameterized definitions of all types of text blocks required under that style.

[0167] S42-2: Search the text template database for a template that matches the desired pattern, and use it as the target design template.

[0168] S42-3: Based on the tire sidewall surface information and the target design scheme template, perform template parameter mapping and adaptation processing to generate the second design scheme.

[0169] Further, this step includes: parsing the parameter items in the parameter table, mapping each parameter item to a specific text block name according to the system's built-in correspondence; traversing the text blocks in the target design scheme template, writing the parameter values ​​in the parameter table into the driving parameters of the text blocks with matching names; and performing geometric adaptation and optimization on the text blocks after writing the new parameters according to the tire sidewall surface information to generate the second design scheme.

[0170] Specifically, when step S4 determines that there is no similar historical expected pattern, the system initiates another search process, namely step S42, which first calls the "text template database". This database is a pre-built, structured solution template library, whose core features are universality and completeness. Each template corresponds to a typical layout style (such as "single brand, centered, double-line, specification with border"), and predefines the parameterized framework of all types of text blocks that may be used under this style. For example, a template with the style "Global Certification" will pre-include the definitions of multiple certification text blocks such as "CCC Certification", "E-mark Certification", "DOT Certification", and "INMETRO Certification", as well as general modules such as brand, specification, and place of origin. Each text block has pre-set reasonable default parameters (such as font, font height, radial relative position), but its circumferential position, specific content, and other key parameters are usually set to null values ​​or pending status to maintain the universality of the template. The database is indexed by template name, style feature tags, etc., supporting fast retrieval.

[0171] The system uses the "desired pattern" (i.e., the abstract layout style of the client's drawing) extracted in step S2 as the query condition to perform a matching search in the text template database. The matching is not based on precise geometric overlap, but rather on the similarity of the layout structure, such as the number of text blocks, the relative positions of main blocks (e.g., brand area, specification area, certification area), and the type of decorative elements. The system uses feature comparison algorithms (e.g., layout descriptor matching) to find one or more generic text templates that are closest to the client's desired layout style. The designer or the system can then select one as the target design template for subsequent adaptation. For example, if the client's drawing shows a layout with "brand at the top, specifications at the bottom, and multiple certification marks arranged centrally on the right," the system might match a template named "Style_RightCertCluster".

[0172] Step 42-3 above: The specific process of template parameter mapping, adaptation and generation of the second design scheme includes:

[0173] Template Instantiation and Parameter Injection: The system loads the selected target template. First, based on customer requirements or existing layout parameters extracted by S2, the template is trimmed and content is filled in. For example, if the customer only needs "E-mark certification," the system automatically deletes redundant text blocks such as "CCC certification" and "INMETRO certification" from the template. Simultaneously, the specific content from the existing layout parameters (such as the brand name "EEEEED" and the specification "295 / 75R22.5") is filled into the corresponding brand and specification text blocks in the template.

[0174] Reference Adaptation and Geometric Calculation: Next, the system performs crucial geometric mapping. Each text block parameter in the template (especially its radial position) is defined relative to a general reference assumed during its design (such as the assumed BW_template). The system reads the current tire's sidewall surface information (specifically R0, R1, W obtained in S2) and uses this as the new reference. Then, following the principle of "relative position ratio unchanged," the absolute coordinates of each text block under the new reference are recalculated. For example, if the radial position of a text block in the template is R_template, its ratio relative to the template reference is (R_template - R0_template) / BW_template. The system applies this ratio to the current tire: R_new = R0_current + ratio W_current, thus completing the position adaptation.

[0175] Intelligent Overwriting Based on Parameter Tables (if Existing): If a specific parameter table exists for this project (potentially from customer specifications or process requirements), the system will perform intelligent overwriting. The parameter table provides precise requirements for specific text blocks in structured data (such as JSON or Excel). The system parses the parameter table, and based on built-in mappings (e.g., the parameter item "Brand_Height" corresponds to the "character height of the brand text block"), accurately locates the corresponding text block in the instantiated and benchmark-adapted solution, and replaces its original parameter with the specified value from the parameter table. For example, if the parameter table specifies that "the character height of the speed level symbol must be 8mm," the system will find the speed level text block and update its character height parameter from the template default value to 8mm.

[0176] Finally, a second design scheme is generated. After the system completes the above-mentioned trimming, content filling, baseline adaptation, and parameter overwriting, it generates a complete second design scheme that is fully adapted to the current tire size and meets the specific content and parameter requirements. This scheme is a parameterized, driveable data set that contains the final content, position, size, and other parameters of all text blocks, preparing for the subsequent manufacturing optimization step S5.

[0177] In this implementation, through step S42, even when there is no directly reusable historical solution, the system can still generate a preliminary design solution that meets the requirements by calling a general template and combining specific parameters for intelligent adaptation, thus ensuring full coverage and high efficiency of the design process.

[0178] It should be noted that after obtaining the second design scheme through step S42, steps S5 and S6 of the aforementioned embodiment can be executed using this second design scheme to complete a complete design process and obtain the complete and desired text and graphic design. For details, please refer to the description of steps S5 and S6 above, which will not be repeated here.

[0179] Optionally, in another embodiment, a specific process for achieving "visual distortion correction" and "morphological optimization" from the process of optimizing and adjusting the manufacturing process is also disclosed.

[0180] This embodiment is a detailed description of the automated setting steps for the specific geometric shape and layout parameters of text blocks during the aforementioned "design scheme" generation process. This implementation method is usually executed after the preliminary geometric position of the "first design scheme" or "second design scheme" is determined. It is a key step that allows for refined and parameterized control of the visual presentation of text before or during step S5 (manufacturing optimization), ensuring that the generated text has an accurate and aesthetically pleasing shape on the three-dimensional curved surface.

[0181] Specifically, including:

[0182] (1) Text content and basic style definition. The system first defines the core attributes of each text module. For example, text content: directly read from the design scheme parameters, such as brand name, specification code, etc.

[0183] Basic style parameters, such as font height: specifies the absolute height of the text. Width factor: by setting a scaling factor α, the text is horizontally scaled while keeping the font height constant, achieving a widening or flattening effect. The transformation formula is to perform a (x×α, y) operation on each coordinate point (x, y) on the text outline. Tilt angle: by setting an angle β, the overall tilt of the text is achieved. During the transformation, the Y value of each coordinate point remains unchanged, while the X value is offset by y×tan(β).

[0184] (2) Adaptive surface deformation (circular arc processing). To ensure that the text in the graphic design perfectly fits the cylindrical surface of the tire sidewall, the system provides three levels of circular arc deformation algorithms, automatically recalculating the coordinates of each coordinate point of the text outline:

[0185] Horizontal Arcing: The text deforms in the horizontal direction (circumferential direction of a tire), simulating perspective stretching / compression on a cylindrical surface, while remaining unchanged in the vertical direction. The core of the algorithm is to calculate the new coordinates (x1×cos(A0), y1 × (L0-δy) / L0)×sin(A0) on the arc based on the center point P0 of the text arrangement, the overall angle A0, and the position of each point relative to the center line.

[0186] Vertical circular arcing: The text deforms in the vertical direction (tire radial direction) to simulate its fit in areas with varying radius (such as the sidewall surface), while remaining unchanged in the horizontal direction. The algorithm calculates the radial proportion ra of each point relative to the text center point P0, and scales the text outline radially to obtain new coordinates (x2 + L1×ra×cos(A0), y2 + L1×ra×sin(A0)).

[0187] Fully rounded: Apply the "horizontal rounding" and "vertical rounding" transformations in sequence to deform the text in both horizontal and vertical dimensions, thus perfectly adapting to the three-dimensional hyperbolic surface of the tire sidewall.

[0188] (3) Overall layout parameter settings. After defining the form of a single text module, the system automatically sets the arrangement of multiple text modules, specifically including:

[0189] Spacing control includes character spacing (distance between characters), word spacing (distance between words), and line spacing (distance between lines of multi-line text).

[0190] Alignment: Sets the alignment reference within or between text blocks, including radial alignment (top, center, bottom) and circumferential alignment (front, center, back).

[0191] Layout Rules: Define the overall arrangement of the text sequence. For example, linear layout: text is arranged along a straight line. Arc layout: text is arranged along an arc of a specified radius, with the characters always pointing towards the center of the arc. Spacing Strategy: You can choose to vary the spacing with the radius (in arc layout, the character spacing automatically adjusts with the radius to maintain visual uniformity), keep the spacing constant (fixed physical distance), or maintain the overall length (automatically adjusts the character spacing to meet the specified total arc length).

[0192] In this embodiment, the system automatically calculates and applies appropriate width coefficients, camber angles, and (horizontal / vertical / full) circular arc transformations based on the precise geometric information (R0, R1, curvature) of the tire sidewall surface, and sets optimal layout parameters to generate a visually upright and aesthetically pleasing "manufacturable solution" on a three-dimensional tire. This ensures a high degree of consistency between digital design and the visual representation of the physical product, and is a key technical link in achieving high-quality output in the intelligent design process.

[0193] See Figure 7a to Figure 7c This is a schematic diagram illustrating the processing of text in a text template database provided in this embodiment. The embodiment includes the following processing steps:

[0194] ① Character processing:

[0195] Extract glyphs from the text template database and display them in 3D software to facilitate designers in modifying and viewing design schemes.

[0196] When the design scheme has special requirements for font processing, such as aspect ratio adjustment, arc transformation, etc., the text is processed using text templates from the text template database. Some of the processing is as follows: a. Aspect ratio adjustment:

[0197] The extracted text is processed by a tool. Using the center point of each character as a reference, the coordinates of each position are calculated. Then, based on the aspect ratio β, while keeping the Y coordinate constant, the X value is scaled. The new X coordinate is obtained by X×β. In 3D software, the transformed coordinates are processed into graphic elements and displayed, as shown below. Figure 7a As shown.

[0198] b. Symbolization transformation:

[0199] When arranging fonts in a horizontal arc, ensure the width remains unchanged, and adjust the horizontal straight lines to align with the concentric arcs.

[0200] One possible implementation is: obtain the coordinates of all font elements; while keeping the X-value unchanged, convert the Y-value into the distance between the current point and the origin to generate a circularly rounded point; reprocess all points into font elements and display them, as shown below. Figure 7b and Figure 7c As shown. Here, XY refers to the coordinates recorded when the font is stored as a font library. The center of the font is at the origin, and each stroke of the font is composed of points; the X and Y directions of these points are X / Y.

[0201] Vertical arcing: Keep the height unchanged, and adjust the width to the sector area of ​​the circle in the arrangement.

[0202] One possible implementation is to obtain the coordinates of all the graphic elements of the font, obtain the current center position of the font, calculate the ratio of the distance from the current horizontal position point to the origin of the coordinate system to the distance from the center point of the font to the origin of the coordinate system, then convert the horizontal distance from the point to the center of the font according to the ratio to obtain the coordinates after vertical arcing, process the transformed coordinates into graphic elements, and display them.

[0203] Fully Arc-Style: Fully Arc-Style: Adjusts the horizontal direction to an arc and the numerical direction to a sector.

[0204] One possible implementation is to obtain the coordinates of all the graphic elements of the font, convert the Y value into the distance between the current point and the origin of the coordinate system to generate a circular point, and then calculate the final coordinates based on the horizontal distance from the center of the font. The transformed coordinates are then processed into graphic elements and displayed.

[0205] ② Spacing optimization:

[0206] One implementation involves calculating the outer contour of the font and creating a bounding box based on that contour. Then, using the bounding box and measured position points, the horizontal spacing is converted to arc length / chord length, and the center point position of each character is calculated. Finally, the center points of the characters are arranged according to the calculated results.

[0207] This embodiment also provides a tire sidewall text design generation device, which is used to implement the above embodiments and preferred embodiments, and will not be repeated as already described. As used below, the term "module" or "unit" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0208] This embodiment provides a device for generating text designs on tire sidewalls, such as... Figure 8As shown, the device includes: an acquisition module 810, an extraction module 820, a matching module 830, a processing module 840, an adjustment module 850, and a program generation module 860. Furthermore, the device may include other modules or units, and this embodiment does not impose any limitations on this.

[0209] The acquisition module 810 is used to acquire the electronic drawing of the tire design to be processed, and to extract the sidewall surface information and text layout parameters from the electronic drawing of the tire design.

[0210] Extraction module 820 is used to extract the desired pattern representing the layout style of text and decorative elements from the electronic drawing of the tire design.

[0211] The matching module 830 is used to perform a matching search in a preset text design scheme repository using the desired pattern as the search condition. The text design scheme repository stores multiple historical design schemes and their associated historical desired patterns.

[0212] The processing module 840 is used to retrieve a historical design scheme bound to the similar historical expected pattern from the text design scheme repository when a historical expected pattern similar to the expected pattern exists in the text design scheme repository; and to adapt the text block parameters in the historical design scheme based on the text layout parameters to generate a first design scheme that matches the current tire size.

[0213] The adjustment module 850 is used to optimize and adjust the first design scheme based on the tire sidewall surface information to generate a manufacturable scheme.

[0214] The program generation module 860 is used to convert the manufacturable scheme into a CNC machining program and transmit it to the machining equipment for execution, so as to form a text pattern design on the tire sidewall that is consistent with the desired pattern.

[0215] In some optional implementations, the extraction module 820 is specifically used to acquire all geometric elements in the tire design electronic drawing, extract solid lines from the geometric elements and sort them, filter the sorted solid lines, delete invalid solid lines, identify and separate the end curves and the middle curve from the remaining elements after filtering, and remove invalid end curves based on the relative positional relationship of their lowest points, retaining the feature curves that characterize the main surface of the tire sidewall; calculate the connection points of adjacent curve segments in the feature curves, and identify non-tangent connection points as key feature points, as at least part of the tire sidewall surface information.

[0216] In some alternative implementations, the processing module 840 is specifically used to obtain the historical reference parameters on which the historical design scheme was based in the original design; obtain the current reference parameters extracted from the tire design electronic drawing; recalculate and map the position parameters and size parameters of all text blocks in the historical design scheme according to the proportional relationship between the historical reference parameters and the current reference parameters, and generate the first design scheme.

[0217] In some alternative implementations, the adjustment module 850 is specifically used to perform one or more of the following compensatory adjustments on the first design scheme based on the sidewall surface information: surface normal compensation, visual distortion correction, and adjustment of processability and interference verification; and to edit the adjusted design scheme according to the final design requirements, and set the final shape and layout parameters of the text and patterns to generate a manufacturable scheme.

[0218] Optionally, in some other embodiments, a construction module is also included. This construction module is used to extract the file name or preset identifier of any design scheme as its unique identifier when the design scheme is completed; generate a standardized vector graphic that completely corresponds to the layout of the text and decorative elements of the design scheme, and use the standardized vector graphic as a historical expected graphic associated with the design scheme; associate and store the parametric driving parameters of all text blocks in the design scheme with the unique identifier and the historical expected graphic, wherein the driving parameters include at least one or more of the following: text content, radial position, circumferential position, character height, and character width ratio; and store the unique identifier, associated driving parameters, and historical expected graphic as a searchable graphic set in the text design scheme repository.

[0219] In some alternative implementations, the processing module 840 is further configured to, when there is no historical desired drawing similar to the desired drawing in the text design scheme repository, read the text template database, search the text template database for a template that matches the desired drawing, and use it as the target design scheme template; and perform template parameter mapping and adaptation processing based on the tire sidewall surface information and the target design scheme template to generate a second design scheme.

[0220] The text template database stores multiple generic text templates corresponding to specific layout styles. Each generic text template contains parameterized definitions of all types of text blocks required under that style.

[0221] Furthermore, the processing module 840 is specifically used to parse the parameter items in the parameter table, map each parameter item to a specific text block name according to the system's built-in correspondence; traverse the text blocks in the target design scheme template, write the parameter values ​​in the parameter table into the driving parameters of the text blocks with matching names; and perform geometric adaptation and optimization on the text blocks after writing the new parameters according to the tire sidewall surface information to generate the second design scheme.

[0222] The tire sidewall text design generation device provided in this application has the following beneficial effects:

[0223] 1. This device automatically and intelligently matches, retrieves, and reuses mature historical solutions from a knowledge base. Utilizing parametric automatic adaptation technology, it quickly matches design solutions to new tire sizes, achieving a paradigm shift from "manual creative design" to "intelligent retrieval and automatic adaptation." This avoids a large amount of repetitive manual labor, freeing designers from tedious geometric adjustments, significantly shortening the design cycle, reducing reliance on operators' professional experience, and thus substantially reducing labor and time costs.

[0224] 2. This device establishes a standardized "textual design scheme repository," which solidifies historical successful schemes and their precise parameters as corporate knowledge assets. Utilizing retrieval and reuse mechanisms, it ensures that new designs automatically inherit high-quality layouts and parameters validated in production. This fundamentally guarantees a high degree of consistency and standardization in design quality across different batches and from different personnel, contributing to a unified brand image and stable product quality.

[0225] 3. In traditional processes, design and machining programming are disconnected, requiring manual resetting of numerous manufacturing parameters, which is error-prone and inefficient. This invention addresses this by using the step "based on the sidewall surface information, optimizing and adjusting the first design scheme for manufacturing processes to generate a manufacturable scheme." Before generating the final scheme, it automatically optimizes and adjusts the design based on precise sidewall surface information (such as surface normal compensation, visual distortion correction, and interference checks), placing manufacturing constraints and process knowledge at the design stage. This ensures that the generated "manufacturable scheme" naturally meets machining requirements. Combined with automatic code generation in the final step, it achieves a one-click, seamless conversion from the optimized design scheme to the CNC program, eliminating information distortion and human error risks associated with traditional multi-stage conversions. This ensures the accurate realization of design intent in the final product, improving first-piece success rate and overall production efficiency.

[0226] 4. Enhanced flexibility, balancing individual needs with rapid response. This system is not a rigid template application. Intelligent retrieval and parameterized adaptation enable the system to quickly respond to customer demands for established styles, while also adapting to different tire specifications by modifying parameters. Simultaneously, the system provides pathways for designing entirely new styles (such as through other branches or template libraries), ensuring efficiency and standardization while also catering to market demands for personalized tire appearance and diverse designs, thereby enhancing the company's market responsiveness and competitiveness.

[0227] In another embodiment, such as Figure 9As shown, this application also provides a tire mold arc text design system 100 for performing the methods described in the above embodiments.

[0228] Specifically, the tire mold arc text design system 100 is a professional software platform integrating intelligent design, knowledge management, and automatic programming. Its core objective is to achieve full automation and intelligence from customer design input to CNC machining program output, significantly improving the efficiency, quality, and standardization of tire sidewall text design. The system mainly consists of three core modules that work together to form a complete design-manufacturing closed loop.

[0229] The system includes: a template library management module 110, a text design module 120, and a program generation module 860.

[0230] Specifically, the template library management module 110 is the knowledge and data hub of the system, responsible for standardized management and access control of all reusable resources.

[0231] The template library management module 110 includes: a text template database 1101, a text design scheme storage library 1102, a design knowledge base creation module 1103, a permission management module 1104, and / or a storage module 1105, etc. The functions of each module are as follows:

[0232] Among them, the text template database 1101 is used to store vector graphics libraries of various standardized text font outlines and commonly used decorative patterns. It supports retrieval by name, provides basic graphic elements for design, and realizes "draw once, call multiple times".

[0233] Text design scheme repository 1102 serves as the system's core knowledge base. It automatically archives all completed historical design schemes, each containing its complete parametric driving data and associated standardized layout patterns ("historical expected patterns"). This repository supports style-based intelligent retrieval, providing a data source for "intelligent recommendations."

[0234] Establish a design knowledge base 1103 to continuously accumulate design rules and special process requirements for different tire specifications and customers, forming callable design constraints and experience rules to guide the generation of new solutions and conflict verification.

[0235] The access control module 1104 is used to manage system resources and functions by level (such as ordinary users, responsible persons, and administrators) to ensure the security of design data and the standardization of operations.

[0236] Storage module 1105 is used to provide unified physical and logical storage services, and manage the persistent storage, backup and version control of all the above databases.

[0237] The text design module 120 is the core of the system's intelligent interaction and generation, carrying the main automated design functions.

[0238] Specifically, the text design module 120 may include: a display module 1201, an intelligent recommendation module 1202, a parametric text design module 1203, and an intelligent error correction module 1204.

[0239] The display module 1201 includes a visualization panel that supports the arrangement of single-part fonts. By setting the shape parameters, position parameters, and processing parameters of the fonts, the fonts can be arranged and displayed in the software according to the designer's intention, making it convenient for the designer to design text layout schemes.

[0240] In addition, the display module 1201 also has an overall adjustment interface, which can extract all the arranged fonts and display the parameters of all fonts on the overall adjustment interface. Designers can adjust the parameters in the overall interface according to the aesthetics, practicality and compliance of the overall design scheme, without having to open the individual design interface for processing.

[0241] The intelligent recommendation module 1202 is the "brain" of the system. After receiving the customer's electronic drawing, it calls the display module 1201 for visualization; automatically extracts the "desired pattern" and tire side parameters from the drawing, and queries the text design scheme repository 1102 for style matching.

[0242] If a match is successful (step S41), similar historical solutions are automatically retrieved from the library, and geometric adaptation is performed based on the current tire parameters to generate a "first design solution" recommended to the user.

[0243] If the matching fails (step S42), the text template database 1101 is called to match the general template according to the style, and instantiate it in combination with the parameter table to generate the "second design scheme".

[0244] The parametric text design module 1203 is used to perform the functions described in the foregoing embodiments, such as ① character shape processing and ② spacing optimization. For a detailed description of the functions, please refer to the foregoing embodiments, which will not be repeated here.

[0245] The intelligent error correction module 1204 is used to automatically check for interference of text blocks in the design and recommendation process, whether they exceed the layout area, and whether they comply with process specifications, and provides modification prompts.

[0246] The display module 1201 is also used to provide two-dimensional and three-dimensional graphical interfaces to display design schemes, tire sidewall surfaces and intelligent recommendation results in real time, so as to realize human-computer interaction and effect preview.

[0247] exist Figure 9In the system shown, the program generation module 860 serves as the system's manufacturing output interface, responsible for converting the optimized digital design scheme into machine tool executable instructions.

[0248] The program generation module 860 includes: a font processing module 1301, a parameter extraction and conversion module 1302, a tool and machining strategy intelligent recommendation module 1303, and a code generation and output module 1304.

[0249] The font processing module 1301 is used to receive the final text scheme from the text design module and perform final pre-manufacturing processing on the text outline, such as stroke connection and corner rounding, to meet the engraving process requirements.

[0250] Specifically, for example Figure 2 As shown, the font in the design scheme is a flat font. However, in actual processing, it is necessary to convert the flat font into the height of relevant graphic elements on the tire sidewall according to the designer's intention. At this time, the font height needs to be adjusted to meet the designer's requirements after processing. The specific adjustment steps are as follows:

[0251] Extract the font height and radial position from the design scheme; extract the tire sidewall curve and find the corresponding font position on the tire sidewall curve; calculate the proportion of the processed font by combining the adjustment benchmark in the font parameters; select an appropriate adjustment scheme. If the designer requires arc length, use the fitting strategy for adjustment; if the designer requires chord length, use compression to achieve the designer's requirements.

[0252] For example, suppose a customer requires a 10mm height on the tire sidewall curve, but the tire sidewall curve is an arc. If processed directly, the lettering height on the sidewall curve would be greater than 10mm after processing. The solution is to adjust the height to match the 10mm height of the sidewall curve, while keeping the width unchanged. Figure 2 As shown, AB represents the character height L, and after bonding, the arc length D-A' is the actual processed character height. Similarly, the chord length ensures that the chord length of D-A' is L.

[0253] The parameter extraction and conversion module 1302 is used to accurately extract the geometric data, depth information, surface normals, etc. of all text and patterns from the "manufacturable scheme" and convert them into standard toolpath intermediate data.

[0254] The tool and machining strategy intelligent recommendation module 1303 is used to automatically match suitable tool models from the process library based on text features (such as the height of the L character and the width of the strokes) and material information, and recommend machining parameters such as spindle speed and feed rate.

[0255] The code generation and output module 1304, as the final post-processor, is used to compile the toolpath and machining strategy according to the syntax rules of the target CNC system to generate the final NC program, which can be transmitted to the machining equipment via network or medium.

[0256] It should be understood that the system described in this embodiment may include more or fewer modules or units, and this embodiment does not impose any limitations on this.

[0257] This system integrates three main modules: template library management, intelligent design recommendation, and automatic program generation. It automates the entire process of tire mold arc text design, from drawing input to machining program output. Through knowledge accumulation and intelligent reuse, it transforms the traditional design and programming process, which relies on manual experience, into an intelligent process driven by parameterization and automated adaptation. This significantly improves design efficiency and accuracy, reduces manual operation costs and error rates, and ensures consistent product quality.
