Description

Technical Field

[0001] The present invention relates to the field of product innovation design, and in particular to a creative design system based on the creativity of consumer groups. Background Art

[0002] With the rapid development of mobile Internet technology and big data-driven artificial intelligence systems, a new consumer era centered on consumers has begun. The traditional product design model dominated by designers' experience and wisdom is increasingly unable to meet consumers' ever-changing personalized needs. The design field urgently needs extensive participation from consumer groups.

[0003] At present, the research on consumer group participation in design mainly focuses on a single stage of design, such as extensively collecting fragmented and fuzzy user needs in the early stage of design and accurately mapping them to product models; providing users with intuitive product appearance images for evaluation in the middle stage of design and using interactive genetic algorithms to optimize products; and introducing users to participate in design decisions in the finalization stage of the design plan in the late stage. A full-process consumer group participation innovation model has not been formed, the consumer group participation is insufficient, and the participation model is unclear.

[0004] The development of mobile Internet technology has provided more opportunities for integrating the wisdom of consumer groups into the product design process and assisting designers in carrying out product creative design activities. In order to allow group participants to better and continuously participate in the design process, a creative design method based on the creativity of consumer groups is proposed, inviting consumers to participate in the entire process from the early creative inspiration of the product to the output of the later design plan. In the early stage of product design inspiration inspiration, users are invited to upload design inspiration through the interactive platform; in the mid-term creative iteration and optimization stage of the product, designers and consumer groups jointly improve the design plan through multi-round collection, multi-round iteration and multi-stage interactive evaluation; in the later stage of product design plan optimization, combined with immersive display methods, invite consumer groups to participate in the comprehensive evaluation of the final plan. Summary of the invention

[0005] The present invention provides a creative design system based on the creativity of consumer groups, which aims to overcome the deficiencies in the prior art and allow users to participate in the entire creative design cycle. On the one hand, users can provide designers with a continuous source of inspiration, further improving the breadth and depth of product creative design; on the other hand, it can meet the needs of diverse consumer groups and enhance the sense of participation and identity of consumer groups.

[0021] A design task acquisition module for the consumer group to obtain and view creative design tasks;

[0022] A design inspiration upload module for the consumer group to submit original inspiration documents according to the design task; and

[0023] Creative solution evaluation module: used for consumer groups to evaluate the creative concept points, design drafts, and design solutions uploaded by designer groups.

[0024] As a preferred solution of the present invention, the design inspiration integration unit deeply analyzes various types of original inspiration documents uploaded by consumer groups, generates a design inspiration integration report, and sends it to the design inspiration acquisition module of the designer's PC work terminal.

[0025] As a preferred solution of the present invention, the specific implementation process of the design inspiration integration unit is as follows:

[0026] 1) Determination of the optimal number of product attributes: Extract product attributes from the original inspiration documents uploaded by consumer groups based on the LDA topic model; calculate the similarity between product attributes by specifying the number of product attributes; determine the optimal number K of product attributes according to the principle that the smaller the similarity, the better the model.

[0027] 2) Determination of the "product attribute - inspiration element" set: One product attribute corresponds to several inspiration elements, that is, one product attribute is an inspiration element set. Based on the LDA modeling results, output a "product attribute - inspiration element" probability distribution document, which represents the probability distribution of relevant inspiration elements in the product attributes.

[0028] 3) Calculation of product attribute importance: Based on the LDA modeling results, output the "original inspiration document - product attribute" probability distribution. The greater the contribution degree of a product attribute in the original inspiration document, the more frequently the product attribute is mentioned, and the more important this product attribute is. Use the contribution probability of the product attribute to the original inspiration document to measure the importance degree of the product attribute. The sum of the contribution probabilities of each product attribute to all original inspiration documents is the importance degree of the product attribute, denoted as PAI k :

[0029]

[0030] In the formula, i represents the original inspiration document number, N represents the total number of original inspiration documents, and PACP k,i represents the contribution probability of product attribute k to the original inspiration document i;

[0031] Normalize the product attribute importance PAI k and denote it as In the formula, K is the number of product attributes k;

[0032]

[0033] 4) Calculation of inspiration element novelty and consistency:

[0034] The inspiration elements under product attribute k Novelty represents the degree of uniqueness of the inspiration element; It can be expressed as:

[0035]

[0036] In the formula, IP i represents the probability distribution of the inspiration element under its product attributes, which can be obtained based on the "product attribute - inspiration element" probability distribution document; N k is the sum of the number of inspiration elements under this product attribute; A is a set coefficient;

[0037] Inspiration element under product attribute k Consistency represents the degree of commonality of group preferences, which is expressed as:

[0038]

[0039] B is a set coefficient;

[0040] 5) After calculating the novelty and consistency of the inspiration elements, filter the original inspiration documents containing inspiration elements with higher novelty and / or consistency, and summarize to obtain a design inspiration integration report.

[0041] As a preferred solution of the present invention, the evaluation result analysis unit is used to analyze and summarize various design evaluation data uploaded by the consumer group, generate a design evaluation report, and send the evaluation report to the designer - consumer evaluation feedback module;

[0042] As a preferred solution of the present invention, the evaluation result analysis unit uses the TOPSIS method based on rough numbers to evaluate the creative solutions for the consumer group and the designer group; and sets corresponding rules for the participation degrees of the designer group and the consumer group, comprehensively combines the evaluation results of the consumer group and the designer group, screens the creative solutions, and the solutions passed through the screening are improved and evolved by the designer group and then returned to the evaluation end, and the design iteration is gradually realized through multiple rounds of evaluation.

[0043] As a preferred solution of the present invention, the specific implementation process of the evaluation result analysis unit is as follows:

[0044] 1) Generation of evaluation indicators and initial population:

[0045] Based on the collected consumer group preferences, n evaluation indicators are formed, and the evaluation indicator Ev = {Ev j , j = 1, 2, …, n}, Ev j represents the j - th evaluation indicator;

[0046] The designer group generates m creative concepts based on various design inspirations uploaded by the consumer group to form an initial population. The initial population Dd = {Dd i , i = 1, 2, …, m}, where Dd i represents the i-th creative concept;

[0047] 2) TOPSIS evaluation method based on rough numbers

[0048] The consumer group Cg = {Cg p , p = 1, 2, …, s} and the designer group (Dg = {Dg q , q = 1, 2, …, t} conduct creative vitality evaluations on m design concepts under n evaluation indicators. Among them, Cg p is the p-th consumer group participant, Dg q is the q-th designer group participant, and s and t are the total numbers of participants in the consumer group and the designer group respectively. It is carried out step by step according to the steps of "constructing the initial evaluation matrix - rough number processing of the initial evaluation matrix - determining the positive ideal solution and the negative ideal solution - calculating the distances between each scheme and the positive ideal solution and the negative ideal solution - calculating the relative closeness of the conceptual scheme to the ideal target - assigning stage weights and calculating the comprehensive evaluation index" to obtain the relative closeness RC i of the consumer group and the relative closeness DQE i of the i-th creative concept point. Then, weights are assigned to RC i and DQE i , and the comprehensive evaluation index WE i is obtained through synthesis;

[0049] Among them, corresponding rules are set for the participation degrees of the designer group and the consumer group: in the process of multiple rounds of iteration, it is set that as the number of iterations increases, the evaluation discourse power of the consumer group gradually decreases, and the evaluation discourse power of the designer group gradually increases. Then, the comprehensive evaluation index of the l-th (l > 1) round of creativity D di is

[0050]

[0051] In the formula, C l (0 ≤ C l ≤ 1) is the discourse power coefficient of the consumer group evaluation in the comprehensive evaluation, D l (1 ≤ D l ≤ 2) is the discourse power coefficient of the designer group evaluation in the comprehensive evaluation, C l + D l = 2, and as the round number l increases, D l increases, and C l decreases accordingly; WE iThe larger the value, the better the comprehensive index of the evaluated creative design product, and the better the fusion model;

[0052] 3) Scheme screening and iteration

[0053] Set a comprehensive evaluation threshold δ. The design concepts with comprehensive evaluation indicators exceeding the threshold are screened. The designers optimize the design according to the group evaluation, and the modified scheme enters the evaluation iteration process again, that is, set l = l + 1; The design concepts with comprehensive evaluation indicators lower than the threshold do not enter the evaluation iteration process; The generated design drafts are all stored in the cloud design process resource library;

[0054] In the evaluation iteration process of the creative scheme, when there are creative schemes with excellent enough comprehensive evaluation meeting the design requirements; or when the entruster of the design project terminates this stage, this stage terminates, and the designers group deepens to form the final scheme.

[0055] As a preferred scheme of the present invention, the design inspiration uploading module is used to collect the creative inspirations of the consumer group; When any one of the following conditions is met, the inspiration collection terminates:

[0056] ① The entruster of the design project terminates the inspiration collection process, including time expiration and the existence of a sufficient number or sufficient excellent design inspirations to meet the design requirements of the designers group;

[0057] ② Use the methods of manual evaluation and machine similarity learning to calculate the creative vitality of the creative points. When the similarity between design inspirations gradually increases and exceeds the set threshold, it indicates that the design inspirations have been basically explored;

[0058] When the inspiration collection terminates, the inspiration data is uploaded to the cloud server for design inspiration integration.

[0059] As a preferred scheme of the present invention, the design inspiration uploading module is used for the consumer group to submit original inspiration documents according to the design task, including text-based inspirations, voice-based inspirations, image-based inspirations and video-based inspirations.

[0060] As a preferred scheme of the present invention, the consumer personal information collected by the consumer login module includes personal design preference information; After the creative design task submitted by the designer's PC working terminal is uploaded to the cloud storage module, the cloud server matches the registered consumer mobile creative terminals that meet the characteristics of the target users of the design according to the consumer information and pushes them.

[0061] Compared with the prior art, the creative design system of the present invention adopts the combination of mobile terminals and the cloud, enabling consumer users to participate in the entire creative design cycle, uploading design concepts and evaluating creative schemes anytime and anywhere, and uploading the data to the cloud for in-depth data processing, facilitating designers to carry out creative design activities.

[0062] The advantages and beneficial effects of the present invention are as follows: The creative design system based on the creativity of consumer groups of the present invention allows users to participate in the entire creative design cycle. The usage knowledge, usage experience, and personalized needs of consumer groups regarding products endow ordinary users with innovative advantages that professional designers do not possess, providing a continuous source of inspiration for designers, further enhancing the breadth and depth of product creative design; at the same time, user participation in design evaluation adds a more objective and scientific basis for designers to improve design schemes, can meet the needs of diverse consumer groups, and also enhance the sense of participation and recognition of consumer groups.

[0067] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be clearly and completely described below in conjunction with specific examples.

[0068] As Figure 1 shown, this example provides a creative design system based on the creativity of consumer groups, which consists of a consumer mobile creative terminal, a designer PC work terminal, and a cloud server:

[0069] The cloud server includes:

[0070] A cloud design resource library for storing and displaying the original inspiration documents uploaded by consumer groups, the design process of jointly improving design schemes by designer groups and consumer groups, and the final design outputs of designer groups;

[0071] A group participant information resource library for managing the information of consumer groups and designer groups;

[0072] A cloud storage module for storing the data submitted by the designer PC work terminal and the consumer mobile creative terminal; and

[0073] A data processing module for analyzing and processing the data submitted by the designer PC work terminals and consumer mobile creative terminals. The data processing module includes a design inspiration integration unit for integrating and summarizing various types of original inspiration documents uploaded by the consumer group, and an evaluation result analysis unit for analyzing and summarizing various types of design evaluation data;

[0074] The designer PC work terminals include:

[0075] A designer login module for implementing the registration and login functions of the participants in the designer group;

[0076] A design task publishing module for the designer group to publish creative design tasks;

[0077] A design inspiration acquisition module for the designer group to obtain a design inspiration integration report;

[0078] A design scheme drawing module for submitting and modifying creative concept points, design drafts, and design schemes;

[0079] A creative scheme evaluation module: for the designer group to evaluate creative concept points, design drafts, and design schemes within the group; and

[0080] A consumer evaluation feedback module for obtaining evaluation reports on creative design schemes from the consumer group and the designer group;

[0081] The consumer mobile creative terminals include:

[0082] A consumer login module for the consumer group to register and log in, and collect personal information of the participants in the consumer group;

[0083] A design task acquisition module for the consumer group to obtain and view creative design tasks;

[0084] A design inspiration upload module for the consumer group to submit original inspiration documents according to the design tasks; and

[0085] A creative scheme evaluation module: for the consumer group to evaluate the creative concept points, design drafts, and design schemes uploaded by the designer group.

[0086] The application process of the system of the present invention is as Figure 2As shown in the figure: ① Design inspiration stimulation stage: After the designer submits a creative design task from the PC work terminal and uploads it to the cloud storage module, the cloud automatically matches the registered consumer mobile creative terminals that meet the characteristics of the target users of the design. Consumers can selectively view and participate in the design task. Consumers participating in the design upload various design creative inspirations to the cloud storage module and the data processing module according to the design requirements. The cloud server stores and generates an integrated report of design inspirations representing the preferences of the masses and sends it to the design inspiration acquisition module of the designer's PC work terminal; ② Creative iteration and optimization stage: The designer forms a creative draft based on the group preference report and uploads it to the cloud server. The cloud server sends it to the matching consumer mobile creative terminals. The designer and consumers evaluate the draft submitted by the designer, collect the scoring values of the users for the creative plan in the form of a 5-point scale. The cloud data processing module analyzes the evaluation data, comprehensively considers the evaluation results of the consumer group and the designer group, screens the creative plan, and the plan passed the screening is improved and evolved by the designer and then returned to the consumer mobile creative terminal. Through multiple rounds of evaluation, the design is gradually iterated until the final goal is achieved and then enters the next stage; ③ Design plan optimization stage: With the help of mobile augmented reality technology, the evolved product creative design plan is displayed. The consumer group can evaluate the product plan under a more realistic experience. The cloud data processing module analyzes the evaluation data and feeds back the final plan to the designer's PC work terminal and the consumer mobile creative terminal.

[0087] In a specific embodiment of the present invention, the application process and each module of the system are introduced in detail:

[0088] Step 1: The consumer user registers relying on the consumer login module and uploads information such as gender, date of birth, education level, job, place of residence, hometown, and personal design preferences to the cloud group participant information resource library;

[0089] In a specific implementation of the present invention, the personal preference information includes plane, UI, web page, illustration, animation, space, product, film and television, handicraft, and clothing. The user needs to select at most three of the above preference information. The personal preference information and other account information are used for the cloud to push design tasks matching the user and for the user to participate in the design.

[0090] Step 2: After the designer submits a creative design task from the PC work terminal and uploads it to the cloud storage module, the cloud automatically matches and pushes the registered consumer mobile creative terminals that meet the characteristics of the target users of the design. Consumers can selectively view and participate in the design task. Consumers can also search for relevant tasks by themselves;

[0091] In a specific implementation of the present invention, only when the user's personal information matches the design target positioning can the user participate in the design.

[0092] Step 3: The consumers participating in the design upload various design creative inspirations to the cloud storage module and the data processing module according to the design requirements. The design creative inspirations uploaded by the users include text-based design inspirations, voice-based design inspirations, image-based design inspirations, and video-based design inspirations. In a specific implementation of the present invention, the text-based design inspirations and voice-based design inspirations refer to the design inspirations expressed in the form of text or voice by the users according to the design requirements of the product, combined with their personal experience of using the same type of product and life experience, including suggestions for improving product drawbacks and prospects for product upgrades. The image-based design inspirations include design sketches, photos, engineering drawings, paintings, etc., which are divided into overall appearance design inspirations, detailed color matching design inspirations, pattern-ground design inspirations, and material texture design inspirations. Among them, the appearance design inspiration represents the user's expectation for the appearance of the product; the color matching design inspiration represents the consumer's expectation for the color combination of the product, and the sources of color matching inspiration include landscape photos, art paintings, film and television works, etc.; the pattern-ground design inspiration represents the consumer's expectation for the printing of the product; the material texture design inspiration represents the consumer's expectation for the material and surface treatment process of the product. The video-based design inspiration refers to expressing the user experience or design prospect of the product in the form of a video, and mainly shows ① the usage method through the video, including usage scenarios, usage steps, core functions, conveniences or inconveniences during use, etc. ② Designs that are closely related to the product design and highly meet the psychological expectations seen in real life, the Internet, books, etc.

[0093] The conditions for stopping the inspiration collection process are one of the following two. When any of the following conditions is met, the inspiration collection terminates: ① The commissioner of the design project terminates the inspiration collection process, including the time limit and the existence of a sufficient number or sufficient quality of design inspirations to meet the designer's design requirements. ② The creative vitality of the creative points is calculated by using the methods of manual evaluation and machine similarity learning. When the similarity between design inspirations gradually increases and the creative vitality gradually remains at a low level, it indicates that the design inspirations have been basically explored.

[0094] Step 4: After the inspiration collection process ends, the cloud storage module stores it in the design inspiration resource library, and the cloud data conducts in-depth analysis on these massive data to generate a design inspiration integration report representing the preferences of the masses, as Figure 3 shown. First, preprocess the group inspiration data, and then use the Latent Dirichlet Allocation (LDA) model and the calculation method proposed in the present invention to quantify the novelty and consistency of the creative inspirations, and screen out the niche creative inspirations with higher novelty and the common creative inspirations with commonalities. Combine text mining and manual marking to identify creative concepts, and then propose product design strategies. The specific steps are as follows:

[0095] 1) Determination of the optimal number of product attributes: Extract product attributes from the original inspiration documents uploaded by the consumer group based on the LDA topic model; By specifying the number of product attributes, calculate the similarity between each product attribute; According to the principle that the smaller the similarity, the better the model, determine the optimal number K of product attributes;

[0096] 2) Determination of the "product attribute - inspiration element" set: One product attribute corresponds to several inspiration elements, that is, one product attribute is an inspiration element set. Based on the LDA modeling results, output the "product attribute - inspiration element" probability distribution document, which represents the probability distribution of relevant inspiration elements in the product attributes;

[0097] 3) Calculation of product attribute importance: Based on the LDA modeling results, output the "original inspiration document - product attribute" probability distribution. The greater the contribution degree of a product attribute in the original inspiration document, the more frequently the product attribute is mentioned, and the more important this product attribute is; Use the contribution probability of the product attribute to the original inspiration document to measure the importance degree of the product attribute. The sum of the contribution probabilities of each product attribute to all original inspiration documents is the importance degree of this product attribute, denoted as PAI k :

[0098]

[0099] In the formula, i represents the original inspiration document number, N represents the total number of original inspiration documents, and PACP k,i represents the contribution probability of product attribute k to the original inspiration document i;

[0100] Normalize the product attribute importance PAI k and denote it as In the formula, K is the number of product attributes k;

[0101]

[0102] 4) Calculation of inspiration element novelty and consistency:

[0103] The novelty of the inspiration element under product attribute k is the degree to describe the uniqueness of this inspiration element;

[0104]

[0105] In the formula, IP i represents the probability distribution of the inspiration element under its product attribute, which can be obtained based on the "product attribute - inspiration element" probability distribution document; N kIt is the sum of the number of inspiration elements under this product attribute; multiplying by 10,000 is to make the result more observable.

[0106] Inspiration elements under product attribute k Consistency It is to describe the degree of common preference of the group. The calculation of consistency can help designers find the mass demand and product design direction faster. It is expressed as:

[0107]

[0108] 5) Propose product design strategies:

[0109] After calculating the novelty and consistency of the inspiration elements, filter the original inspiration data that contains inspiration elements with higher novelty and consistency. A higher novelty indicates that the creative design is more niche and more likely to produce breakthrough innovations; a higher consistency indicates that the creative design conforms to the mass preference and is more in line with the market trend. After obtaining the "niche inspiration" and "mass inspiration", perform manual marking according to the four elements of "users, usage scenarios, product features, and creative inspiration", and obtain creative concepts from the user inspiration data more intuitively and vividly.

[0110] Step 5: The designer outputs a design draft according to the product design strategy, and uses the TOPSIS method based on rough numbers to evaluate the creative solutions for the consumer group and the designer group. On this basis, set corresponding rules for the participation of the designer group and the consumer group, and comprehensively screen the creative solutions based on the evaluation results of the consumer group and the designer group. The solutions that pass the screening are improved and evolved by the designer and then returned to the evaluation end, and the iteration of the design is gradually realized through multiple rounds of evaluation. The specific steps are as Figure 4 shown:

[0111] 1) Evaluation indicators and initial population generation:

[0112] Form evaluation indicators based on the consumer preferences collected in Phase I, and supplement and screen the evaluation indicators in combination with the opinions of relevant experts and designers, denoted as Ev = {Ev j , j = 1, 2,..., n}. In a specific application example of the present invention, the indicators are defined as novelty, practicability, and aesthetics.

[0113] The designer generates a certain amount of creative concepts based on various design inspirations uploaded by group participants to generate an initial population, denoted as Dd = {Dd i , i = 1, 2,..., m}.

[0114] 2) TOPSIS evaluation method based on rough numbers

[0115] Organize the consumer group (Cg = {Cgp , p = 1, 2, …, s}) and the designer group (Dg = {Dg q , q = 1, 2, …, t}) conduct a creative vitality evaluation on m design concepts under n evaluation indicators. It is carried out step by step according to the steps of "constructing the initial evaluation matrix - rough number processing of the initial evaluation matrix - determining the positive ideal solution and the negative ideal solution - calculating the distances between each scheme and the positive and negative ideal solutions - calculating the relative closeness of the conceptual scheme to the ideal target - assigning stage weights and calculating the comprehensive evaluation index", and the relative closeness RC i of the consumer group and the relative closeness DQE i of the designer group for the i-th creative concept point are obtained. Then, weights are assigned to RC i and DQE i , and the comprehensive evaluation index WE i is comprehensively obtained.

[0116] Among them, considering the professional background, corresponding rules are set for the participation degrees of the designer group and the consumer group: In the process of multiple rounds of iteration, considering that designers have received systematic design thinking training and their evaluations of products are more professional and scientific, it is thus set that as the number of iterations increases, the evaluation discourse power of consumers gradually decreases, and the evaluation discourse power of designers gradually increases. Then, the comprehensive evaluation index of the l-th (l > 1) round of creativity D di is

[0117]

[0118] In the formula, C l (0 ≤ C l ≤ 1) is the discourse power coefficient of consumer evaluation in the comprehensive evaluation, D l (1 ≤ D l ≤ 2) is the discourse power coefficient of designer evaluation in the comprehensive evaluation, C l + D l = 2, and as the round number l increases, D l increases, and C l decreases accordingly. The larger the value of WE i , the better the comprehensive index of the evaluated creative design product, and the better the fusion model.

[0119] 3) Scheme screening and iteration

[0120] Set the comprehensive evaluation threshold δ. The design creativity with the comprehensive evaluation index exceeding the threshold (i.e., WE i ≥ δ) passes the screening. The designer optimizes the design according to the group evaluation, and the modified scheme enters the evaluation iteration process again, l = l + 1. The comprehensive evaluation index is lower than the threshold (i.e., WE iDesign ideas with a deviation less than or equal to δ do not enter the refinement and iteration process. The generated design drafts are all stored in the cloud design process resource library.

[0121] In the stage of refining the creative solution, when any one of the following conditions is met, this stage terminates, and the designer further develops it into the final solution: there is a creative solution with a comprehensive evaluation excellent enough to meet the design requirements; the client of the design project terminates this stage.

[0122] Step 6: Model and render the creative drafts finally passed through screening in Step 5, and then use mobile augmented reality technology to display the solution more realistically. To make the evaluation results more in line with the market, the evaluation in this stage is completely carried out by consumers. The evaluation process refers to the description of the TOPSIS evaluation method based on rough numbers in Step 5, and is carried out in the steps of "constructing the initial evaluation matrix - rough number processing of the initial evaluation matrix - determining the positive ideal solution and the negative ideal solution - calculating the distances between each solution and the positive ideal solution and the negative ideal solution - calculating the relative closeness of the conceptual solution to the ideal target - calculating the comprehensive evaluation index" to obtain the optimal solution. The design solution is stored in the cloud to the design output resource library, and the final solution is fed back to the designer's PC work terminal and the consumer's mobile creative terminal.

[0123] The design output resource library module is used to store and display excellent design works. Classified by design fields, it includes graphic design unit, UI design unit, web design unit, illustration design unit, animation design unit, spatial design unit, product design unit, film and television design unit, handicraft design unit, fashion design unit and other design units.

The specific implementation process of the design inspiration integration unit is as follows: 1) Determination of the optimal number of product attributes: Extract product attributes from the original inspiration documents uploaded by the consumer group based on the LDA topic model; calculate the similarity between each product attribute by given the number of product attributes; determine the optimal number K of product attributes according to the principle that the smaller the similarity, the better the model; 2) Determination of the "product attribute - inspiration element" set: One product attribute corresponds to several inspiration elements, that is, one product attribute is an inspiration element set. Based on the LDA modeling result, output a "product attribute - inspiration element" probability distribution document, which represents the probability distribution of relevant inspiration elements in the product attributes; 3) Calculation of product attribute importance: Based on the LDA modeling results, output the probability distribution of "original inspiration document - product attribute". The greater the contribution degree of a product attribute in the original inspiration document, the more frequently the product attribute is mentioned, and the more important this product attribute is. Use the contribution probability of the product attribute to the original inspiration document to measure the importance degree of the product attribute. The sum of the contribution probabilities of each product attribute to all original inspiration documents is the importance degree of this product attribute, denoted as PAI k : where \(i\) represents the original inspiration document number, \(N\) represents the total number of original inspiration documents, and \(PACP\) k,i represents the contribution probability of product attribute \(k\) to the original inspiration document \(i\); Normalize the Product Attribute Importance (PAI) k and denote it as where K is the number of product attributes k; 4) Calculation of the novelty and consistency of inspiration elements: Inspiration elements under product attribute k Novelty represents the degree of uniqueness of the inspiration element; It can be expressed as: where IP i represents the probability distribution of inspiration elements under their product attributes, which can be obtained based on the "product attribute - inspiration element" probability distribution document; N k is the sum of the number of inspiration elements under this product attribute; A is a set coefficient; Inspiration elements under product attribute k Consistency To describe the degree of commonality in group preferences, Expressed as: B is a set coefficient; 5) After calculating the novelty and consistency of the inspiration elements, screen the original inspiration documents containing inspiration elements with higher novelty and / or consistency, and summarize them to obtain a design inspiration integration report; The designer PC work terminal includes: A designer login module for realizing the registration and login functions of each participant in the designer group; A design task release module for the designer group to release creative design tasks; A design inspiration acquisition module for the designer group to obtain a design inspiration integration report; A design scheme drawing module for submitting and modifying creative concept points, design drafts, and design schemes; A creative scheme evaluation module for the designer group to evaluate creative concept points, design drafts, and design schemes within the group; and A consumer evaluation feedback module for obtaining the evaluation reports of the consumer group and the designer group on the creative design scheme; The consumer mobile creative terminal includes: A consumer login module for the consumer group registration and login functions and collecting personal information of each participant in the consumer group; A design task acquisition module for the consumer group to obtain and view creative design tasks; A design inspiration upload module for the consumer group to submit original inspiration documents according to the design tasks; Creative Solution Evaluation Module: Used for consumer groups to evaluate the creative concept points, design drafts, and design solutions uploaded by designer groups.
