Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of digital design, and in particular to an intensive design method and system for product design. BACKGROUND

[0002] The technical field of digital design involves using computer-aided tools, software and systems to perform design work, improve design efficiency and quality, and reduce error rates and costs. This technical field includes 3D modeling, computer-aided design, digital construction and virtual reality technologies. Designers can create, modify, analyze and optimize product designs in a digital environment. Digital design makes the design process more flexible, enabling rapid adaptation to market changes and customer needs, while also supporting the implementation and management of complex projects.

[0003] Among them, the intensive design method for product design refers to the use of centralized and systematic strategies in digital design to improve design efficiency and consistency. This method involves integrating various resources and elements at the beginning of the design process to ensure optimization of the design process and improvement of product quality. Using intensive design methods can reduce resource waste, speed up design decisions, and improve the overall performance and market competitiveness of products during product development. This method is particularly suitable for situations where multiple products or complex systems need to be developed in a short period of time.

[0004] Although existing technologies improve the flexibility and adaptability of design in the field of digital design, they face challenges in resource integration and management efficiency under rapidly changing market conditions. The resources in the design process are not intensive enough, resulting in low efficiency in resource utilization and collaborative work. For example, the lack of effective version control and change record mechanisms leads to redundant work and misoperation in design modification, increasing error rates and delaying project progress. The assessment of the impact of design changes is not systematic and comprehensive, making it difficult to accurately judge the actual impact of changes on product performance and cost in a timely manner, leading to decision-making errors and resource waste. The lack of an effective rollback mechanism is also an important deficiency of existing technologies, making it difficult to quickly recover to a more effective previous design state when design decisions are proven to be wrong, increasing risk and cost. SUMMARY

[0058] Please refer to Figure 1 The embodiments of the present application provide an intensive design method for product design, and the processing flow of the method can include the following steps:

[0059] S1: Collect the initial draft of product design, record through version control, extract the metadata of design file and archive, the metadata includes designer information, timestamp and design version, and obtain product design record;

[0060] S2: Capture the intensive design changes re-submitted by using the product design record, analyze the metadata of product intensive design file, identify the differences between the previous and subsequent designs, record the change points and change amount, and obtain deviation analysis result;

[0061] S3: Based on the deviation analysis result, identify the content of product design changes, analyze the influence of product intensive design changes on product performance, cost and schedule, and obtain change impact evaluation result;

[0062] S4: Through the change impact evaluation result, identify and classify the product design that meets the preset target of intensive design, perform rollback operation on the intensive design that does not meet the product requirement, and restore to the specified previous design state, and obtain rollback version file;

[0063] S5: Adopting rollback version file, analyzing the matching degree of product design change and original design standard of intensive design with business demand, and updating the version control state of design file in real time, obtaining product intensive design log.

[0064] The product design record includes the timestamp of design completion, the version number of design, and the associated technical parameters. The deviation analysis result includes the list of change points, the numerical value of change amount, and the information of influence range. The change influence evaluation result includes the parameters of product performance influence, the budget estimate of cost change, and the time framework of progress adjustment. The rollback version file includes the design information of previous version, associated parameters, and configuration information. The product intensive design log includes the update record of design version, the matching check result of design standard, and the satisfaction degree of business demand.

[0065] Please refer to Figure 2 , collect the initial draft of product design, record through version control, extract the metadata of design file and archive, the metadata includes designer information, timestamp and design version, the steps to obtain product design record are as follows:

[0066] S101: Collect the initial draft of product design, record the associated information of design initial draft, including design drawings and specification, conduct electronic scanning of design file, convert into digital format, the execution process of design information data set is as follows:

[0067] Thoroughly record the design drawings and specifications, including the details and size specifications of technical drawings, conduct electronic scanning of design file and convert into digital format, not only require the use of high-resolution scanning equipment to capture every detail of the drawings, but also need to use advanced image recognition technology such as OCR (Optical Character Recognition) to convert graphic information into digital data, the application of technology ensures the accuracy of data entry and the efficiency of subsequent processing, in order to further improve the usability and security of data, the scanned digital files need to be preliminarily cleaned and formatted to ensure that the information in the data set is consistent and standardized, supporting deeper data analysis and application, such as version control and cloud storage, and the metadata of the file is labeled, such as creation date, file type and author information, which is crucial for subsequent document management and version tracking, obtaining design information data set.

[0068] S102: Based on the design information data set, update and modify the design file through version control, set automatic tracking of the date and time of each file save, automatically synchronize and update to cloud backup, the execution process of version control data set is as follows:

[0069] Set automatic tracking of the date and time of each file save, according to the formula:

[0070] T=ti+1 -t i ;

[0071] In the formula, T represents the time interval, t i and t i+1 represent the time stamps of two consecutive file saves respectively;

[0072] Set the file to be modified three times on a certain day, with time stamps t1=08:00, t2=12:00, and t3=15:00. According to the formula, the time interval between the first and second modifications is calculated as:

[0073] T1=12:00-08:00=4;

[0074] The time interval between the second and third modifications is:

[0075] T2=15:00-12:00=3;

[0076] The time interval helps to understand the modification frequency of the file, which is a key parameter in the version control process, and can help system administrators and designers monitor project progress and frequently modified areas.

[0077] S103: Use the version control dataset to extract the product design completion timestamp and design version number metadata, perform information encoding optimization data security, and obtain the product design record execution process as follows:

[0078] By extracting the completion timestamp and version number of each design file, accurate monitoring and recording of the design process is achieved. The key operation is information encoding optimization, which includes encryption processing of sensitive information such as timestamp and version number to prevent unauthorized access and potential data leakage. During the encoding process, data formatting is also required to ensure compliance with internal data management system requirements, such as uniforming the version number format to a specific string format and converting the timestamp to UNIX time format. Such processing not only improves data consistency but also enhances data compatibility, making data exchange between different systems more smooth. The dataset after completing this process can also be used for subsequent security audit and compliance check to ensure that all design activities comply with the enterprise's security policy and industry standards, ensuring the security of design information. At the same time, it also provides a reliable data support for the design team, which can quickly respond to market changes and customer demands, and obtains product design records.

[0079] Please refer to Figure 3 , using product design records to capture intensive design changes submitted again, analyze product intensive design file metadata, identify differences between previous and subsequent designs, record change points and change amounts, and obtain deviation analysis results as follows:

[0080] S201: Based on the product design record, automatically capture the re-submitted design file, perform version comparison on the submitted design file, identify the update of the file version, and obtain the execution process of the re-submitted file set as follows:

[0081] When the design file is re-submitted, the system will automatically trigger the version comparison mechanism, which compares the differences between the existing file and the submitted file through algorithm to determine the update of the file version. The comparison includes the changes of the file content, the specific location of the modification, and the range of the modification. Through this automatic comparison, the system can quickly identify the updated content in the newly submitted design file, including all the updated or modified design files. This technology not only improves work efficiency, but also reduces the probability of human error, ensuring the accuracy and reliability of the design file update and management process, helping to track project progress and review design changes, and obtaining the re-submitted file set.

[0082] S202: Using the re-submitted file set, extract the metadata of each version of the design file, compare the designer information, timestamp, and version number between the differential versions, mark the difference points of the product design, and obtain the execution process of the metadata difference comparison record as follows:

[0083] Compare the differential versions. The core of this process is to analyze the metadata of the design file, which includes designer information, timestamp, and version number. Through data comparison, the difference points in the product design can be marked, such as tracking the timeline of file modification by comparing the timestamp, and revealing the parts responsible by different designers through the comparison of designer information, and directly displaying the order and frequency of file iteration through the difference of version number. The marking of difference points is crucial for understanding the reasons and purposes of design changes, providing in-depth insights into the change history in the product development process for the design team, which not only helps to improve design quality, but also supports more efficient project management and quality control, obtaining the metadata difference comparison record.

[0084] S203: Using the metadata difference comparison record, perform quantitative analysis of the product design change content, including size adjustment and material replacement, calculate the influence degree percentage of design change, and obtain the execution process of the deviation analysis result as follows:

[0085] The formula for calculating the influence degree percentage of design change is:

[0086]

[0087] Where R is the influence degree percentage of design change, O i represents the quantitative value of the size or material before the i-th product design change, P iQuantitative value of size and material after the i th product design change, n represents the total number of parameters;

[0088] Parameter meaning and set value:

[0089] O i Quantitative value of a certain design parameter before change, including original size or material strength, data obtained from design records or product specification;

[0090] P i Quantitative value of the corresponding design parameter after change, data also from updated design documents;

[0091] n represents the total number of parameters, determined according to the design change list of the project;

[0092] Sum of squared differences of all changes, quantifying the dispersion of design changes; Sum of absolute values of all changed parameters, used as the basis for normalization, to ensure the generality of the calculation;

[0093] Put the parameters into the formula for calculation: set three design parameter changes, O1=15, P1=12, O2=30, P2=35, O3=45, P3=40, then:

[0094]

[0095]

[0096] The result 8.83% indicates the average degree of influence caused by design changes, through which the influence range of overall design changes on product performance or characteristics can be observed, providing an intuitive understanding of the influence of changes.

[0097] See Figure 4 Based on the deviation analysis results, identify the content of product design changes, analyze the influence of product intensive design changes on product performance, cost and schedule, and obtain the change impact evaluation results. The steps are as follows:

[0098] S301: Identify the content of intensive design changes of product design through deviation analysis results, including changed component specifications, material types and design parameters, and obtain the design change content record. The execution process is as follows:

[0099] Comparative analysis of design deviations and actual products to determine the need for changes in component specifications, material types and design parameters, during which a professional design team uses advanced analysis tools and techniques such as CAD software and 3D modeling to ensure the accuracy and efficiency of the analysis, through the tools, the team can quickly identify the deviations compared with the original design, and determine the specific change scheme, including the adjustment of component size, the update of material specification and the optimization of design parameters, the determination of changes is based on the performance requirements and cost-benefit analysis of the product to ensure that the changed product can maintain or improve performance while controlling costs, during the change process, the feasibility of change implementation must also be considered, including the availability of materials and the adjustment ability of the production line, to provide reliable data support for subsequent design modification and product optimization, and obtain design change content records.

[0100] S302: According to the design change content record, evaluate the potential impact of intensive design changes on product performance, including performance optimization parameters, estimate the extension and shortening of progress, and generate progress analysis results. The execution process is as follows:

[0101] Evaluate the potential impact of intensive design changes on product performance according to the formula:

[0102] I p = αΔP + βΔT;

[0103] In the formula, I p represents the impact index of intensive design changes, α and β represent the weight factors of performance improvement and progress adjustment respectively, ΔP represents the change amount of performance parameters, and ΔT represents the change time of estimated progress;

[0104] Set the performance of a certain product to be improved by 10% through intensive design changes, and the estimated completion progress to be shortened by 5 days, set the weight factor of performance improvement α = 0.6, and the weight factor of progress adjustment β = 0.4, according to the formula:

[0105] I p = 0.6 × 10 + 0.4 × (-5) = 6 - 2 = 4;

[0106] The results show that the overall impact of intensive design changes on product performance is positive, which indicates that the performance improvement exceeds any adverse effects of progress shortening, and it is an effective design change strategy.

[0107] S303: Use progress analysis results to perform intensive design impact analysis, refer to the changes in performance, cost and progress, and obtain change impact evaluation results. The execution process is as follows:

[0108] The analysis process needs to consider all relevant variables and influencing factors, such as the performance improvement means higher material costs or more complex production processes, and the progress adjustment affects the product launch time and market share. Through professional data analysis tools and team collaboration, the factors can be quantitatively analyzed to determine which design changes are the most cost-effective. At the same time, the analysis results will also involve the potential impact on supply chain management and production processes, considering how to optimize the cost and progress without sacrificing product quality. After completing the analysis, not only does it provide the basis for decision-makers to implement specific changes, but also provides a scientific basis for predicting product market performance and consumer satisfaction. The change impact assessment results are obtained.

[0109] Please refer to Figure 5 , through the change impact assessment results, identify and classify the intensive design of the product design that meets the preset target, and perform rollback operation on the intensive design that does not meet the product requirements, and restore to the specified previous design state, and obtain the rollback version file. The steps are as follows:

[0110] S401: Use the change impact assessment results to perform classification analysis of design changes, calculate the compliance score of the design version, and obtain the compliance classification record. The execution process is as follows:

[0111] The formula for calculating the compliance score of the design version is as follows:

[0112]

[0113] Wherein, AC is the compliance score value of each design version, P represents the score of the preset performance target, C a represents the score of cost control, S represents the score of progress requirement, W p represents the performance weight coefficient, W c represents the cost weight coefficient, and W s represents the progress weight coefficient.

[0114] Parameter meaning and setting value:

[0115] P represents the score of the preset performance target, which is obtained through performance test. If a design meets 90% of the expected performance, P = 90.

[0116] C a represents the score of cost control, which is calculated according to the ratio of actual expenditure to budget. If the actual expenditure does not exceed the budget, C a = 100, and it is reduced by the same proportion if it exceeds the budget.

[0117] S represents the score of progress requirement, which is calculated according to the time of project completion. If it is completed on time, S = 100, and it is reduced by 10 points for each week of delay.

[0118] W p W is the performance weight coefficient, which is set according to the industry standard, for example, if the performance is 50% important in the project, then W p = 0.5;

[0119] W c W is the cost weight coefficient, which is set according to the budget impact on the success of the project, for example, if cost control is critical, W c = 0.3;

[0120] W s W is the progress weight coefficient, which takes into account the impact of progress on customer satisfaction, for example, if progress control is critical, W s = 0.2;

[0121] Substitute the parameters into the formula for calculation: set the specific situation as: P = 90, C a = 95 (completed within budget, slightly saved), S = 80 (slightly delayed), W p = 0.5, W c = 0.3, W s = 0.2;

[0122] The calculation process is as follows:

[0123]

[0124] The results show that the compliance score of the design change is higher, mainly affected by good performance and cost control, although the progress is slightly delayed, the overall design change meets the predetermined target, and the score is used to mark the compliance classification record, and the design version is sorted according to the score, which provides a basis for subsequent decision-making.

[0125] S402: Use the compliance classification record to backtrack the product intensive design change marked as not meeting the preset target, access the specified previous design state through version control, perform version rollback operation, and the execution process of the design rollback operation record is as follows:

[0126] Accessing the specified previous design state through the version control function, the version control system stores detailed records of each design version, including change content, change time, designer, and reason for change. Through detailed information, the specific design version that does not meet the preset target can be quickly located, and the process of performing version rollback operation involves complex data processing and software operation, which requires safely rolling back the current design state to a previous state, which requires the system not only to technically ensure the accuracy of the operation, but also to ensure that the data will not be lost or damaged during the rollback process. In order to ensure the accuracy and efficiency of the rollback process, the design team needs to closely monitor the system's rollback operation and perform necessary checks and verifications to ensure that the design files after rollback can be accurately restored to the target state, and the design rollback operation record is obtained.

[0127] S403: Based on the design rollback operation record, restore the product design to the specified previous version state, verify the consistency of the restored design file with the original file in performance, cost and schedule, and store the rolled back version, and the execution process of generating the rollback version file is as follows:

[0128] Restoring the product design to the specified previous version state, the key to this process is to verify the consistency of the restored design file with the original file in performance, cost and schedule. By comparing the design files before and after rollback, the team can evaluate in detail any differences caused by the rollback operation and the impact of the differences on product performance, cost and delivery time. This verification process involves complex technical analysis and cooperation of multiple departments, including design department, quality control and project management, to ensure that every detail meets the original design requirements. The rolled back version needs to be stored in a secure data environment, and the database and document management system are updated to reflect the latest version state, maintaining the integrity and consistency of the design file. In order to quickly locate and restore to the historical state at any time during the entire product development cycle, the rollback version file is generated.
