Description

Technical Field

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

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

[0003] Among them, the intensive design method of product design refers to the use of centralized and systematic strategies in digital design to improve the efficiency and consistency of design. This method involves integrating various resources and elements in the early stages of design to ensure the optimization of the design process and the improvement of product quality. The use of intensive design methods can reduce resource waste, accelerate 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 have improved the flexibility and adaptability of designs 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 concentrated enough, resulting in inefficiencies in resource utilization and collaborative work. For example, the lack of effective version control and change record mechanisms leads to redundant work and misoperations in design modifications, increasing error rates and delaying project schedules. The assessment of the impact of design changes is not systematic and comprehensive enough, making it difficult to accurately and timely determine the actual impact of changes on product performance and cost, leading to wrong decisions and waste of resources. The lack of an effective rollback mechanism is also an important shortcoming of existing technologies. When a design decision is proven to be wrong, it is difficult to quickly restore to a more effective previous design state, increasing risks and costs. Summary of the invention

[0033]

[0034] Where AC is the compliance score of each design version, P represents the score of the preset performance target, and C a represents the score of cost control, S represents the score of schedule requirement, and W represents the score of p Represents the performance weight coefficient, W c Represents the cost weight coefficient, W s Represents the progress weight coefficient.

[0035] As a further solution of the present invention, the steps of using the rollback version file to analyze the product design changes of the intensive design and the matching degree between the original design standards and business requirements, and updating the version control status of the design file in real time to obtain the product intensive design log are specifically as follows:

[0058] See also Figure 1 The embodiment of the present invention provides an intensive design method for product design. The processing flow of the method may include the following steps:

[0059] S1: Collect the draft of product design, record it through version control, extract the metadata of design files and archive them. The metadata includes designer information, timestamp and design version, and obtain product design records;

[0060] S2: Use product design records to capture the resubmitted intensive design changes, analyze the metadata of product intensive design files, identify the differences between the previous and the next designs, record the change points and the amount of change, and obtain the deviation analysis results;

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

[0062] S4: Identify and classify the product designs that meet the preset goals through the change impact assessment results, perform a rollback operation on the intensive design that does not meet the product requirements, restore it to the specified previous design state, and obtain a rollback version file;

[0063] S5: Use the rollback version file to analyze the product design changes of the intensive design and the degree of matching between the original design standards and business requirements, and update the version control status of the design file in real time to obtain the product intensive design log.

[0064] Product design records include the timestamp of design completion, design version number, and associated technical parameters. Deviation analysis results include a list of change points, numerical values ​​of changes, and information on the scope of impact. Change impact assessment results include parameters affecting product performance, budget estimates of cost changes, and time frames for schedule adjustments. Rollback version files include design information, associated parameters, and configuration information of previous versions. Product intensive design logs include update records of design versions, matching check results of design standards, and the degree to which business requirements are met.

[0065] See also Figure 2 , collect the draft of product design, record it through version control, extract the metadata of design files and archive them. The metadata includes designer information, timestamp and design version. The specific steps to obtain product design records are:

[0066] S101: Collect the draft of product design, record the relevant information of the draft design, including design drawings and specifications, perform electronic scanning of design documents, convert them into digital format, and obtain the execution process of the design information data set as follows;

[0067] Thoroughly record the design drawings and specifications, including the details and dimensional specifications of the technical drawings, and conduct electronic scanning of the design files into digital format. This requires not only the use of high-resolution scanning equipment to capture every detail of the drawings, but also the use of advanced image recognition technology such as OCR (optical character recognition) to convert graphic information into digital data. The application of technology ensures accurate data entry and efficient subsequent processing. In order to further improve the availability and security of data, the scanned digital files need to undergo preliminary data cleaning and formatting to ensure that the information in the data set is consistent and standardized, support deeper data analysis and applications, such as version control and cloud storage, and label the file's metadata, such as creation date, file type and author information, which is crucial for subsequent document management and version tracking, and obtain a design information data set.

[0068] S102: Based on the design information data set, the design file is updated and modified through version control, and the date and time of each file save are automatically tracked, and the update is automatically synchronized to the cloud backup. The execution process of obtaining the version control data set is as follows;

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

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

[0071] Where T represents the time interval, t i and t i+1 Respectively represent the timestamps of two consecutive file saves;

[0072] The file is modified three times on a certain day, and the saved timestamps are t1 = 08:00, t2 = 12:00, and t3 = 15:00. The time interval between the first and second modifications is calculated according to the formula:

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

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

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

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

[0077] S103: Using the version control data set, extract the metadata of the timestamp of product design completion and the design version number, perform information encoding to optimize data security, and obtain the execution process of the product design record as follows;

[0078] By extracting the completion timestamp and version number of each design file, accurate monitoring and recording of the design process can be achieved. The key operation is the optimization of information encoding, which includes encryption of sensitive information such as timestamps and version numbers to prevent unauthorized access and potential data leakage. The data also needs to be formatted during the encoding process to ensure that it meets the requirements of the internal data management system. For example, the format of the version number needs to be unified into a specific string format, and the timestamp needs to be converted into the UNIX time format. Such processing not only improves data consistency, but also enhances data compatibility, making data exchange between different systems smoother. The data set after completing this process can also be used for subsequent security audits and compliance checks to ensure that all design activities comply with the company's security policies and industry standards and ensure the security of design information. It also provides a reliable data support for the design team, enabling rapid response to market changes and customer needs and obtaining product design records.

[0079] See also Figure 3 ,Use product design records to capture the resubmitted intensive design changes, analyze the metadata of product intensive design files, identify the differences between the previous and the next designs, record the change points and the amount of change, and obtain the deviation analysis results. The specific steps are as follows:

[0080] S201: Based on the product design record, the resubmitted design files are automatically captured, version comparison is performed on the submitted design files, and updates of the file versions are identified to obtain the resubmitted file set. The execution process is as follows;

[0081] When a design file is resubmitted, the system will automatically trigger a version comparison mechanism, which uses an algorithm to compare the differences between the existing file and the submitted file to determine the update status of the file version, including changes in file content, the specific location of the modification, and the scope of the modification. Through this automated comparison, the system can quickly identify updated content in the newly submitted design file, including all updated or modified design files. This technology not only improves work efficiency, but also reduces the probability of human error, ensures accuracy and reliability in the design file update and management process, helps track project progress and review design changes, and obtains a resubmitted file set.

[0082] S202: Using the resubmitted file set, extracting the design file metadata of each version, comparing the designer information, timestamp and version number between the differentiated versions, marking the differences in product design, and obtaining the metadata difference comparison record. The execution process is as follows;

[0083] Compare the different versions. The core of this process is to analyze the metadata of the design files, which includes key information such as designer information, timestamps and version numbers. By comparing the data, the differences in product design can be marked. For example, by comparing the timestamps, the timeline of file modifications can be tracked, and the comparison of designer information can reveal the parts of different versions that are responsible for different designers. The difference in version numbers directly shows the order and frequency of file iterations. The marking of differences is crucial to understanding the reasons and purposes of design changes, and provides the design team with in-depth insights into the change history during product development. It not only helps to improve design quality, but also supports more efficient project management and quality control, and obtains metadata difference comparison records.

[0084] S203: Using the metadata difference comparison record, quantitative analysis of product design change content is performed, including size adjustment and material replacement, and the impact percentage of the design change is calculated to obtain the deviation analysis result. The execution process is as follows;

[0085] The formula for calculating the impact percentage of a design change is:

[0086]

[0087] Among them, R is the impact percentage of the design change, O i represents the quantitative value of the size or material before the i-th product design change, P irepresents the quantitative value of the size and material of the i-th product design after the change, and n represents the total number of parameters;

[0088] Parameter meaning and setting value:

[0089] O i It is the quantitative value of a design parameter before the change, including the original size or material strength, and the data is obtained from the design record or product specification;

[0090] P i It is the quantitative value of the corresponding design parameter after the change. The data also comes from the updated design document;

[0091] n represents the total number of parameters, which is determined based on the design change list of the project;

[0092] Represents the sum of squared differences of all changed items, quantifying the discreteness of design changes; Represents the sum of the absolute values ​​of all changed parameters, used as the base for normalization to ensure the generalization of the calculation;

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

[0094]

[0095]

[0096] The result of 8.83% indicates the average impact caused by the design change. This percentage can be used to observe the impact of the overall design change on product performance or characteristics, providing an intuitive understanding of the impact of the change.

[0097] See also Figure 4 Based on the deviation analysis results, identify the content of product design changes, analyze the impact of product intensive design changes on product performance, cost and schedule, and obtain the change impact assessment results in the following steps:

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

[0099] Compare and analyze the design deviations and actual products to determine the component specifications, material types and design parameters that need to be changed. During this process, the professional design team uses advanced analysis tools and technologies, such as CAD software and 3D modeling, to ensure the accuracy and efficiency of the analysis. Through the tools, the team can quickly identify deviations from the original design and decide on specific change plans, including adjustments to component dimensions, updates to material specifications and optimization of design parameters. Changes are determined based on product performance requirements and cost-benefit analysis to ensure that the changed product can control costs while maintaining or improving performance. During the change process, the feasibility of implementing the changes must also be considered, including the availability of materials and the ability to adjust the production line, to provide reliable data support for subsequent design modifications and product optimization, and to obtain records of design changes.

[0100] S302: Based on the design change content record, evaluate the potential impact of the intensive design change on product performance, including performance optimization parameters, estimate the extension and shortening of the schedule, and generate the schedule 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 schedule adjustment respectively, ΔP represents the change amount of performance parameters, and ΔT represents the estimated duration of schedule change;

[0104] Assume that the performance of a product is improved by 10% through intensive design changes, and the estimated completion schedule is shortened by 5 days. Set the performance improvement weight factor α = 0.6, and the schedule adjustment weight factor 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, indicating that the performance improvement outweighs any adverse effects of schedule reduction and is an effective design change strategy.

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

[0108] The main reference is to changes in performance, cost and schedule. During this analysis process, all relevant variables and influencing factors need to be considered comprehensively. For example, performance improvement means higher material costs or more complex production processes, and schedule adjustments affect product launch time and market share. Through professional data analysis tools and team collaboration, 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 potential impacts on supply chain management and production processes, considering how to optimize costs and schedules without sacrificing product quality. After completing the analysis, it not only provides decision makers with a basis for implementing specific changes, but also provides a scientific basis for product market performance and consumer satisfaction predictions, and obtains change impact assessment results.

[0109] See also Figure 5 , through the change impact assessment results, identify and classify the product designs that meet the preset goals of the intensive design, perform a rollback operation on the intensive design that does not meet the product requirements, and restore it to the specified previous design state. The specific steps for obtaining the rollback version file are:

[0110] S401: Using the change impact assessment results, perform classification analysis on the 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 a design version is as follows:

[0112]

[0113] Where AC is the compliance score of each design version, P represents the score of the preset performance target, and C a represents the score of cost control, S represents the score of schedule requirement, and W represents the score of p Represents the performance weight coefficient, W c Represents the cost weight coefficient, 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 testing. If a design meets 90% of the expected performance, then P = 90;

[0116] C a It represents the score of cost control, which is calculated based on the ratio of actual expenditure to budget. If the actual expenditure does not exceed the budget, C a =100, if the budget is exceeded, it will be reduced proportionally;

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

[0118] W p is the performance weight coefficient, which is set according to industry standards. If the importance of performance in this project is 50%, then W p =0.5;

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

[0120] W s is the progress weight coefficient. Considering the impact of progress on customer satisfaction, if progress control is the key, 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, with slight savings), S = 80 (slight delay), 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 high, mainly affected by good performance and cost control. Although there are slight delays in the schedule, the overall design change meets the predetermined goals. The score is used to mark the compliance classification record, and the design versions are sorted according to the score to provide a basis for subsequent decision-making.

[0125] S402: Using the conformity classification record, the product intensive design changes marked as not conforming to the preset target are traced back, and through version control, the specified previous design state is accessed to perform a version rollback operation, and the execution process of obtaining the design rollback operation record is as follows;

[0126] The specified previous design state is accessed through the version control function. The version control system stores detailed records of each design version, including the changes, change time, designer, and reasons for the changes. Through the detailed information, the specific design version that does not meet the preset goals can be quickly located. The process of performing version rollback operations involves complex data processing and software operations. The current design state needs to be safely rolled back to a previous state. This requires the system to not only technically guarantee the accuracy of the operation, but also ensure that the data will not be lost or damaged during the rollback process. In order to ensure the accuracy and efficiency of the tracing process, the design team needs to closely monitor the system's rollback operations and perform necessary inspections and verifications to ensure that the rolled-back design files can be accurately restored to the target state and obtain the design rollback operation records.

[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 terms of performance, cost and schedule, and store the rolled back version. The execution process of generating the rolled back version file is as follows;

[0128] Restore the product design to a specified previous version state. The key to this process is to verify the consistency of the restored design files with the original files in terms of performance, cost and progress. By comparing the design files before and after the rollback, the team can evaluate in detail any differences caused by the rollback operation, as well as the impact of the differences on product performance, cost and delivery time. This verification process involves complex technical analysis and cooperation among multiple departments, including the 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 status. Maintaining the integrity and consistency of the design files is the key to this process, so that during the entire product development cycle, the historical state can be quickly located and restored at any time to generate a rollback version file.

[0129] See also Figure 6 , using the rollback version file, analyzing the product design changes of the intensive design and the matching degree between the original design standards and business requirements, and updating the version control status of the design file in real time. The specific steps to obtain the product intensive design log are:

[0130] S501: Use the rollback version file to analyze the matching degree between the rolled-back design file and the original design standard and business requirements, compare the consistency of multiple design parameters with business goals, record the unmatched items and matching parameters, and obtain the matching analysis result. The execution process is as follows;

[0131] Analyze the matching degree between the rolled-back design documents and the original design standards and business requirements according to the formula:

[0132]

[0133] In the formula, M represents the matching index, p match Represents the number of matched parameters, and n represents the total number of parameters;

[0134] Let's take a specific case. The design file involves 10 core business parameters, and the rollback version matches 7 of them. According to the formula:

[0135]

[0136] The results show that 70% of the design parameters are consistent with business requirements and design standards. This result shows that the design file can still meet the original business requirements and design standards well after rollback, which is crucial to maintaining the consistency and practicality of product design. It also shows that those mismatched parameters need to be further analyzed and modified to fully achieve business goals.

[0137] S502: Update the version control status of the design file based on the matching analysis result, automatically update the status of each design review and modification, and obtain the execution process of the real-time update record as follows;

[0138] Evaluate the consistency of various parameters in the design file with business objectives, apply the evaluation results to the real-time version management system, and update the status of each design review and modification. This process ensures that all design documents involved can reflect the latest changes and review results. The automatic update function makes this process efficient and reduces human errors. Whenever a design file is updated or rolled back, the system will automatically record the relevant modification date and time, the modifier, and the specific content of the modification. It is extremely important for maintaining the historical version of the design file and tracking the latest status, ensuring that the design team can quickly access the latest files. It also facilitates the audit and quality control departments to supervise and review, maintain the transparency and consistency of the design process, and obtain real-time update records.

[0139] S503: According to the real-time update record, the version control information of the intensive design file of the product design is integrated, including the corresponding matching of the design version, modification date, designer information and business requirements, and real-time tracking and review are performed to obtain the execution process of the product intensive design log as follows;

[0140] Extensive data integration and real-time tracking of the corresponding matching of design versions, modification dates, designer information to business requirements. The purpose of this integration is to provide a comprehensive perspective to review and evaluate every change in the design process to ensure that all modifications are based on evidence and meet business requirements. The tracking and review mechanism used in this process is automated, which means that any changes will be immediately reflected in the intensive design log, which not only improves work efficiency but also enhances data accuracy and reliability. The real-time review mechanism also helps the design team capture estimated errors or deviations and make immediate adjustments to ensure that product design always meets predetermined quality standards and business goals, and obtains a product intensive design log.

[0141] On the other hand, an electric vehicle state monitoring system is provided, and the electric vehicle state monitoring system is used to execute the above electric vehicle state monitoring method, and the system includes:

[0142] The draft record module collects the draft of product design, records the version, extracts the design file metadata, including designer information, timestamp and design version, and obtains the product design record;

[0143] The deviation identification module uses product design records to capture resubmitted design changes, analyze metadata, identify design differences, record change points and changes, and obtain deviation analysis results;

[0144] The impact analysis module identifies the changes in the intensive design based on the deviation analysis results, analyzes the impact of the intensive design changes on product performance, cost and schedule, and obtains the change impact assessment results;

[0145] The version recovery module uses the change impact assessment results to identify design changes that do not meet the preset goals, performs a history rollback operation, restores to a specified previous design state, and obtains the rollback version file;

[0146] The design matching module uses the rollback version file to analyze the matching degree between the intensive design changes and the original design standards and business requirements, updates the version control status of the design file, and obtains the matching analysis results;

[0147] The design file update module updates the design file version in real time according to the matching analysis results, verifies the consistency of the design file with the real-time business requirements and design standards, and obtains an intensive design log.
