Description

Technical Field

[0001] This invention relates to a product design method, belonging to the field of marine supporting product design, and particularly to a parallel collaborative design method for marine supporting products. Background Technology

[0002] Currently, the design and manufacturing of traditional ship supporting products usually use two-dimensional drawings as the design carrier. When it is necessary to modify the parameters in the two-dimensional drawings, since the parameters are not related, it is necessary to manually identify the influence range of each parameter and modify them one by one. Therefore, the efficiency of drawing modification is low and it is easy to miss.

[0003] Chinese patent application number 202410856469.9, filed on June 28, 2024, discloses a three-dimensional parametric design management method and system for ship support equipment. Based on design management, it performs three-dimensional parametric product design. First, after entering design project information, it enters the parametric design stage, selects a product structure decomposition method, and constructs the overall product layout based on the entered project information. Based on the overall product layout, it guides designers step-by-step to complete the product parametric definition. According to the overall product layout and the complete product parametric definition, it calculates and verifies the logical relationships between product parameters. Under the determined overall product layout, product parameters, and logical relationships between parameters, it uses developed modeling software for automatic modeling, obtaining the final product model, product parameters, and product structure call configuration. Although this design achieves the effect of parameter association between components through the three-dimensional parametric design method, it still has the following shortcomings:

[0004] In this design, a serial design approach was used to complete the product structure decomposition and the parameterization of the product's components. This means that designers need to complete these two tasks sequentially, resulting in a long design time and low design efficiency.

[0005] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects and problems of long design time and low design efficiency in the existing technology, and to provide a parallel collaborative design method for ship supporting products with shorter design time and higher design efficiency.

[0007] To achieve the above objectives, the technical solution of the present invention is:

[0008] A method for parallel collaborative design of ship-related products, the method comprising the following steps:

[0009] Step 1: First, the chief designer designs the definition based on the overall requirements of the product. Then, the chief designer designs the layout sketch based on the definition. Next, the chief designer builds virtual components based on the layout sketch. Finally, the chief designer combines all the virtual components into a skeleton model.

[0010] The second step is for the chief designer to obtain multiple component design tasks based on the skeleton model and layout sketches, and then distribute the multiple component design tasks, skeleton model, and layout sketches to the corresponding designers.

[0011] Step 3: First, the designer completes the component design task. The component design task is as follows: based on the component design task, skeleton model, and layout sketch, the detailed design of the component is carried out, and then the component model is obtained. Then, the layout sketch is updated based on the component model. Then, all the component models are assembled into the final assembly model. Then, the chief designer checks the final assembly model and the layout sketch. If both the final assembly model and the layout sketch are qualified, proceed to step 4. If one or two items in the final assembly and the layout sketch are unqualified, skip to step 2.

[0012] Step 4: First, the chief designer refines the general assembly model, and then reviews the general assembly model. If the review fails, proceed to step 2. If the review passes, the designer designs the detailed data of the parts and components, and then completes the parallel collaborative design of the ship's supporting products.

[0013] In the first step, the layout sketch includes the position information, relative position information, and size information of the components; in the first step, the skeleton model is a model that includes reference surfaces, reference lines, and reference points.

[0014] In the third step, the component model includes a mechanical component model and a specialized component model. The origin of the coordinates of the mechanical component model coincides with the origin of the coordinates of the skeleton model, and the reference plane of the specialized component model coincides with the reference plane of the skeleton model.

[0015] In the fourth step, the review refers to the simulation analysis review and the process review review. The review is qualified when both the simulation analysis report and the process review report are qualified. The review is unqualified when one or both of the simulation analysis report or the process review report are unqualified.

[0016] In the fourth step, the simulation analysis review refers to: first, the simulation analysis technician performs finite element analysis on the overall assembly model based on the component design task, then obtains the simulation model of the overall assembly, and then performs simulation analysis on the simulation model from the aspects of stiffness, strength, stability, and whether there is stress concentration, and then obtains the simulation analysis report. Then, based on the simulation analysis report, it is judged as a qualified result or an unqualified result, and then the results and simulation analysis report are sent to the chief designer.

[0017] In the fourth step, the process review refers to the following: first, the process review personnel review the overall assembly model from the perspective of process manufacturing, based on the component design task, and then review the component design structure, precision, manufacturability, and processing cost in sequence to obtain a process review report. Then, based on the process review report, the result is judged as qualified or unqualified, and the process review report is sent to the chief designer.

[0018] In the fourth step, sending the process review report to the chief designer means: first, sending the process review report to the simulation analysis technician, then the simulation analysis technician makes modification suggestions on the assembly model based on the process review report, and then sending the modification suggestions and the process review report to the chief designer, who then modifies the assembly model based on the modification suggestions and the process review report.

[0019] In the second step, obtaining multiple component design tasks based on the skeleton model and layout sketch means: first, checking the skeleton model and layout sketch into the PLM system, and then obtaining multiple component design tasks in the PLM system based on the skeleton model and layout sketch.

[0020] In the third step, checking the overall assembly model means checking the overall assembly model in the PLM system.

[0021] In the fourth step, reviewing the final assembly model refers to reviewing the final assembly model in the PLM system.

[0022] In the first step, the chief designer constructing virtual components based on the layout sketch means that the chief designer constructs virtual components based on the layout sketch and the component library in the PLM system.

[0023] In the third step, the detailed design of the parts based on the parts design task, skeleton model, and layout sketch refers to the detailed design of the parts based on the parts design task, skeleton model, layout sketch, and fasteners or feature library in the PLM system.

[0024] In the fourth step, the designer's design of detailed component data refers to the designer designing the detailed component data based on the annotation library in the PLM system.

[0025] In the third step, updating the layout sketch means: first updating the corresponding parameters of the layout sketch, and then locking the corresponding parameters of the layout sketch.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the parallel collaborative design method for ship supporting products of the present invention, the method includes the following steps: Step 1: The chief designer designs a layout sketch and skeleton model; Step 2: The designer decomposes multiple component design tasks based on the layout sketch and skeleton model, and then distributes the component design tasks to the corresponding designers; Step 3: Multiple designers complete the component design tasks, and then obtain multiple component models. Then, the layout sketch is updated based on the multiple component models, and the component models are assembled into a final assembly model. Then, the chief designer checks the layout sketch and the final assembly model. If they pass, proceed to Step 4; otherwise, skip to Step 2; Step 4: First, refine the final assembly model, and then review the final assembly model. If the review fails, skip to Step 2; if the review passes, the designer designs the detailed data of the components, and then the method is completed. The advantages of the present invention also include:

[0028] Firstly, this method can be used to design ship-related products.

[0029] Secondly, multiple designers can design components simultaneously, saving design time and improving design efficiency. Furthermore, by sharing component parameters through layout sketches and reference information through skeleton models, not only can the components be uniformly controlled, but the collaborative design effect can also be achieved.

[0030] Thirdly, by sharing component parameters through layout sketches, layout sketches provide overall control during the design process. When a designer modifies one parameter, the other parameters are automatically modified, eliminating the need for manual modification of each parameter and avoiding missed parameter modifications, thus improving design modification efficiency.

[0031] Therefore, the design time of this invention is short and the design efficiency is high.

[0032] 2. In the parallel collaborative design method for ship supporting products of the present invention, in the first step, the layout sketch includes the position information, relative position information, and dimension information of the components, and the skeleton model is a model including reference planes, reference lines, and reference points. In the third step, the component models include mechanical component models and specialized component models. The coordinate origin of the mechanical component model coincides with the coordinate origin of the skeleton model, and the reference plane of the specialized component model coincides with the reference plane of the skeleton model. In application, parameter information is transmitted through the layout sketch, thus achieving parameter sharing among multiple designers, facilitating collaborative design among various mechanical components and kits, and preventing parameter mutual exclusion. The skeleton model provides position and interface references for the components, facilitating collaborative design among mechanical components, kits, electrical, hydraulic, information, and other disciplines. Therefore, the collaborative design effect of the present invention is better.

[0033] 3. In the parallel collaborative design method for ship supporting products of the present invention, the fourth step, the review, refers to: simulation analysis review and process review. The simulation analysis review conducts simulation analysis on the overall assembly model in terms of stiffness, strength, stability, and the presence of stress concentration. The process review review examines the overall assembly model in terms of component design structure, accuracy, manufacturability, and processing cost. The chief designer then reviews both review reports to determine the review results. In application, introducing simulation analysis review and process review during the product design stage minimizes the likelihood of product design modifications due to non-compliance with manufacturing requirements, improves design quality, avoids impacting product development cycles due to unreasonable product design, thereby improving development efficiency and reducing development costs. Therefore, the present invention can reduce development costs.

[0034] 4. In the parallel collaborative design method for ship supporting products of the present invention, in the first step, the chief designer constructs virtual components based on the layout sketch and the component library in the PLM system. In the second step, multiple component design tasks are obtained in the PLM system based on the skeleton model and the layout sketch. In the third step, the overall assembly model is checked in the PLM system. In the fourth step, the overall assembly model is reviewed in the PLM system. The designer performs detailed component design based on the component design tasks, the skeleton model, the layout sketch, and the fastener or feature library in the PLM system. In the fourth step, the designer designs the detailed component data based on the annotation library in the PLM system. In application, the PLM system is used to distribute component design tasks, store component models, and assemble assembly models, facilitating collaborative work. The component library, fastener or feature library, and annotation library in the PLM system can also assist the design process, saving design time and improving product design efficiency, quality, and standardization. Therefore, the present invention has a high degree of standardization.

[0035] 5. In the parallel collaborative design method for ship supporting products of the present invention, in the third step, the corresponding parameters of the layout sketch are first updated, and then the corresponding parameters of the layout sketch are locked. When applied, after a designer completes their design task, they lock the parameter, meaning that other designers cannot modify the parameter, thus avoiding accidental modification by other designers. Therefore, the present invention has the function of preventing accidental modification. Attached Figure Description

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Please see Figure 1 — Figure 8 A parallel collaborative design method for ship-related products, the method comprising the following steps:

[0046] Step 1: First, the chief designer designs the definition based on the overall requirements of the product. Then, the chief designer designs the layout sketch based on the definition. Next, the chief designer builds virtual components based on the layout sketch. Finally, the chief designer combines all the virtual components into a skeleton model.

[0047] The second step is for the chief designer to obtain multiple component design tasks based on the skeleton model and layout sketches, and then distribute the multiple component design tasks, skeleton model, and layout sketches to the corresponding designers.

[0048] Step 3: First, the designer completes the component design task. The component design task is as follows: based on the component design task, skeleton model, and layout sketch, the detailed design of the component is carried out, and then the component model is obtained.

[0049] Step 4: First, the chief designer refines the general assembly model, and then reviews the general assembly model. If the review fails, proceed to step 2.

[0050] In the first step, the layout sketch includes the position information, relative position information, and size information of the components; in the first step, the skeleton model is a model that includes reference surfaces, reference lines, and reference points.

[0052] In the fourth step, the review refers to the simulation analysis review and the process review review. The review is qualified when both the simulation analysis report and the process review report are qualified. The review is unqualified when one or both of the simulation analysis report or the process review report are unqualified.

[0053] In the fourth step, the simulation analysis review refers to: first, the simulation analysis technician performs finite element analysis on the overall assembly model based on the component design task, then obtains the simulation model of the overall assembly, and then performs simulation analysis on the simulation model from the aspects of stiffness, strength, stability, and whether there is stress concentration, and then obtains the simulation analysis report. Then, based on the simulation analysis report, it is judged as a qualified result or an unqualified result, and then the results and simulation analysis report are sent to the chief designer.

[0054] In the fourth step, the process review refers to the following: first, the process review personnel review the overall assembly model from the perspective of process manufacturing, based on the component design task, and then review the component design structure, precision, manufacturability, and processing cost in sequence to obtain a process review report. Then, based on the process review report, the result is judged as qualified or unqualified, and the process review report is sent to the chief designer.

[0055] In the fourth step, sending the process review report to the chief designer means: first, sending the process review report to the simulation analysis technician, then the simulation analysis technician makes modification suggestions on the assembly model based on the process review report, and then sending the modification suggestions and the process review report to the chief designer, who then modifies the assembly model based on the modification suggestions and the process review report.

[0056] In the second step, obtaining multiple component design tasks based on the skeleton model and layout sketch means: first, checking the skeleton model and layout sketch into the PLM system, and then obtaining multiple component design tasks in the PLM system based on the skeleton model and layout sketch.

[0057] In the third step, checking the overall assembly model means checking the overall assembly model in the PLM system.

[0058] In the fourth step, reviewing the final assembly model refers to reviewing the final assembly model in the PLM system.

[0059] In the first step, the chief designer constructing virtual components based on the layout sketch means that the chief designer constructs virtual components based on the layout sketch and the component library in the PLM system.

[0060] In the third step, the detailed design of the parts based on the parts design task, skeleton model, and layout sketch refers to the detailed design of the parts based on the parts design task, skeleton model, layout sketch, and fasteners or feature library in the PLM system.

[0061] In the fourth step, the designer's design of detailed component data refers to the designer designing the detailed component data based on the annotation library in the PLM system.

[0062] In the third step, updating the layout sketch means: first updating the corresponding parameters of the layout sketch, and then locking the corresponding parameters of the layout sketch.

[0063] The following are supplementary descriptions of the present invention:

[0064] The ship-related products mentioned in this invention refer to various electromechanical products installed on ships, including anchor winches, steering gears, cranes, hoists, controllable pitch propellers, etc., all of which can be designed using this invention.

[0065] Example 1:

[0066] Please see Figure 1 — Figure 8 A parallel collaborative design method for ship-related products, the method comprising the following steps:

[0067] Step 1: First, the chief designer designs the definition based on the overall requirements of the product. Then, the chief designer designs the layout sketch based on the definition. Next, the chief designer builds virtual components based on the layout sketch. Finally, the chief designer combines all the virtual components into a skeleton model.

[0068] The second step is for the chief designer to obtain multiple component design tasks based on the skeleton model and layout sketches, and then distribute the multiple component design tasks, skeleton model, and layout sketches to the corresponding designers.

[0069] Step 3: First, the designer completes the component design task. The component design task is as follows: based on the component design task, skeleton model, and layout sketch, the detailed design of the component is carried out, and then the component model is obtained. Then, the layout sketch is updated based on the component model. Then, all the component models are assembled into the final assembly model. Then, the chief designer checks the final assembly model and the layout sketch. If both the final assembly model and the layout sketch are qualified, proceed to step 4. If one or two items in the final assembly and the layout sketch are unqualified, skip to step 2.

[0070] Step 4: First, the chief designer refines the general assembly model, and then reviews the general assembly model. If the review fails, proceed to step 2. If the review passes, the designer designs the detailed data of the parts and components, and then completes the parallel collaborative design of the ship's supporting products.

[0071] Preferably, in the third step, the chief designer's inspection of the general assembly model and layout sketch means that the chief designer checks whether the general assembly model meets the design requirements, whether the layout, structure, and related parameters are consistent with the product design technical requirements, whether it meets the product design specifications, and whether it can achieve the corresponding functional requirements of the product.

[0072] Preferably, in the fourth step, the chief designer's improvement of the assembly model refers to the chief designer improving the design content of the assembly model that does not meet the product design specifications, such as annotations, component structure layout, dimensions, etc., as well as design content that does not meet the product function and performance requirements.

[0073] Example 2:

[0074] The basic content is the same as in Example 1, except that:

[0075] Please see Figure 1 — Figure 8 In the first step, the layout sketch includes the positional information, relative positional information, and dimensional information of the components; in the first step, the skeleton model includes reference surfaces, reference lines, and reference points. In the third step, the component models include mechanical component models and specialized component models. The origin of the coordinate system of the mechanical component models coincides with the origin of the coordinate system model, and the reference surface of the specialized component models coincides with the reference surface of the skeleton model. Preferably, the specialized components include electronic control components, hydraulic components, and information components.

[0076] In application, in the first and third steps, parameter information is shared with designers through the layout sketch. When the chief designer or a designer modifies (i.e. updates) the parameters in the layout sketch, other components that reference those parameters will be automatically updated. Therefore, designers do not need to manually update them one by one. The chief designer will also control the layout sketch to avoid parameter incompatibilities. The coordinate origin of the mechanical component model coincides with the coordinate origin of the skeleton model, that is, the internal positioning of the mechanical components within the product coincides to realize the connection relationship between the mechanical components. The reference plane of the professional component model coincides with the reference plane of the skeleton model to realize the overlap of the interaction interface information between different professional components.

[0077] Example 3:

[0078] The basic content is the same as in Example 1, except that:

[0079] Please see Figure 1 — Figure 6In the fourth step, the review refers to both simulation analysis review and process review. A passing review means both the simulation analysis report and the process review report are satisfactory; a failing review means one or both of the simulation analysis report or the process review report are unsatisfactory. Specifically, the simulation analysis review involves a simulation technician performing finite element analysis on the assembly model based on the component design tasks. This yields a simulation model of the assembly. The simulation model is then analyzed for stiffness, strength, stability, and stress concentration. A simulation analysis report is generated, and the result is determined as either satisfactory or unsatisfactory based on the report. The results and the simulation analysis report are then sent to the chief designer. Similarly, the process review involves a process reviewer examining the assembly model from a manufacturing perspective, considering the component design structure, precision, manufacturability, and manufacturing cost. A process review report is generated, and the result is determined as either satisfactory or unsatisfactory based on the report. The process review report is then sent to the chief designer. In the fourth step, sending the process review report to the chief designer means: first, sending the process review report to the simulation analysis technician, then the simulation analysis technician makes modification suggestions on the assembly model based on the process review report, and then sending the modification suggestions and the process review report to the chief designer, who then modifies the assembly model based on the modification suggestions and the process review report.

[0080] In the application, in the fourth step, the simulation analysis technician first performs finite element analysis on the assembly model based on the component design tasks, thus obtaining a simulation model of the assembly. Then, the simulation model is analyzed in terms of stiffness, strength, stability, and the presence of stress concentration, resulting in a simulation analysis report. Based on the simulation analysis report, the result is determined to be either acceptable or unacceptable. The result and simulation analysis report are then sent to the chief designer. Simultaneously, the process review personnel, based on the component design tasks, review the assembly model from a manufacturing perspective, sequentially examining the component design structure, precision, manufacturability, and processing cost, thus obtaining a process review report. Based on the process review report, the result is then determined to be either acceptable or unacceptable. The process review report is then sent to the simulation analysis technician, who then provides modification suggestions for the overall assembly model based on the process review report. (For example, the process reviewer may suggest that a certain component meets the simulation analysis requirements for stiffness and strength, but is labor-intensive and material-intensive in actual manufacturing, and is not optimal in terms of process. In this case, the simulation analysis technician may propose optimization and improvement methods for the component based on meeting the actual design indicators, such as reducing plate thickness or reducing the number of stiffeners.) The modification suggestions and the process review report are then sent to the chief designer, who then modifies the overall assembly model based on the modification suggestions and the process review report. This completes the review step. If the review is unsatisfactory, the process proceeds to the second step, where the component design tasks are re-decomposed.

[0081] Example 4:

[0082] The basic content is the same as in Example 1, except that:

[0083] Please see Figure 1 — Figure 8 In the second step, obtaining multiple component design tasks based on the skeleton model and layout sketch means: first, checking the skeleton model and layout sketch into the PLM system, and then obtaining multiple component design tasks in the PLM system based on the skeleton model and layout sketch; in the third step, checking the final assembly model means: checking the final assembly model in the PLM system; in the fourth step, reviewing the final assembly model means: reviewing the final assembly model in the PLM system. In the first step, the chief designer constructing virtual components based on the layout sketch means: the chief designer constructs virtual components based on the layout sketch and the component library in the PLM system; in the third step, performing detailed component design based on component design tasks, skeleton model, and layout sketch means: performing detailed component design based on component design tasks, skeleton model, layout sketch, and fastener or feature library in the PLM system; in the fourth step, the designer designing detailed component data means: the designer designs detailed component data based on the annotation library in the PLM system.

[0084] In application, in the first step, the chief designer constructs virtual components based on the layout sketch and the component library in the PLM system. Using the component library in the PLM system allows for quick borrowing and reference of relevant component designs, improving the chief designer's design efficiency. In the second step, the skeleton model and layout sketch are first checked into the PLM system. Then, multiple component design tasks are obtained in the PLM system based on the skeleton model and layout sketch. The PLM system is used to distribute these component design tasks, not only sending messages to notify the corresponding designers to complete their tasks, but also facilitating designers in the third step to refer to the fastener or feature library in the PLM system when completing component design tasks, thus saving design time. After completing the component design tasks... The component models are stored in the PLM system, and then the component models are assembled into a general assembly model in the PLM system. The chief designer then checks the general assembly model and layout sketch. If it is not up to standard, the process jumps to the second step, where the chief designer re-decomposes the model into multiple component design tasks in the PLM system based on the skeleton model and layout sketch. In the fourth step, the general assembly model is reviewed in the PLM system, which facilitates communication between simulation analysis technicians, process reviewers and the chief designer, as well as modifications to the component models or general assembly model. After the review is passed, multiple designers design the detailed component data based on the annotation library in the PLM system. Using the information in the annotation library can save designers' design time.

[0085] Example 5:

[0086] The basic content is the same as in Example 1, except that:

[0087] Please see Figure 1 — Figure 7 In the third step, updating the layout sketch means: first updating the corresponding parameters of the layout sketch, and then locking the corresponding parameters of the layout sketch.

[0088] When applied, after the corresponding designer modifies the corresponding parameters in the layout sketch, the corresponding parameters can be locked to prevent them from being accidentally modified by other designers.

[0089] Example 6:

[0090] Please see Figure 1 — Figure 8 A parallel collaborative design method for anchor winches, the method comprising the following steps:

[0091] Step 1: First, the chief designer defines the overall requirements of the anchor winch. Then, the chief designer designs the layout sketch of the anchor winch based on the definition. Next, the chief designer builds the virtual components of the anchor winch based on the layout sketch. Finally, the chief designer combines all the virtual components into the skeleton model of the anchor winch.

[0092] The second step: First, the chief designer obtains multiple component design tasks based on the skeleton model and layout sketch of the anchor winch. Then, the chief designer distributes the multiple component design tasks, skeleton model, and layout sketch to the corresponding designers.

[0093] Step 3: First, multiple designers complete the design tasks for each component of the anchor winch. The component design tasks are as follows: based on the component design tasks, skeleton model, and layout sketch, detailed design of the components is carried out; then, the component models of the anchor winch are obtained, and the layout sketch is updated based on the component models; then, all the component models are assembled into the overall assembly model of the anchor winch, and then the chief designer checks the overall assembly model and the layout sketch. If both the overall assembly model and the layout sketch are qualified, then proceed to step 4. If one or two items in the overall assembly and the layout sketch are unqualified, then skip to step 2, that is, obtain the component design tasks again.

[0094] Step 4: First, the chief designer refines the overall assembly model of the anchor winch, and then reviews the overall assembly model. If the review fails, proceed to step 2. If the review passes, the designer designs the detailed data of the parts and completes the parallel collaborative design of the anchor winch.

[0095] The above description is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments.
