Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0042] like Figure 1 As shown, a method for making topologically optimized organic furniture comprises the following steps:

[0043] S1. Build a database for storing existing furniture appearance data, organize the database using target image contours and extract key features, and then convert the key features into organic furniture form sketch data;

[0044] S2. Use modeling software to establish an initial geometric model, and import the organic furniture form sketch data into the initial geometric model; determine the overall size and form of the initial geometric model based on indoor environmental parameters and design requirements, and perform mesh optimization of the basic form to generate mesh data;

[0045] S3. Set constraints to filter mesh data, and use topology optimization algorithm to gradually optimize the initial geometric model, remove redundant material structural units and form an organic form. Output a lightweight model based on the optimization results.

[0046] Furthermore, in step S3, the initial geometric model is optimized based on volume constraints using a bidirectional progressive structural optimization algorithm; wherein the mathematical model of the bidirectional progressive structural optimization algorithm is:

[0047]

[0048] xi=0,xi=1

[0049] Where C represents the average strain energy of the structure; F represents the structural load matrix; T represents the pseudo time of iteration during the optimization process; U represents the displacement matrix; V * Represents the target volume of the calculation; vi is the unit volume; xi represents the design variable, which can take the value of "0" or "1", "0" represents the required unit and "1" represents the real unit; V represents the structural volume after N iterations.

[0050] Furthermore, a bidirectional progressive structural optimization algorithm is used for continuous calculations, and then the initial geometric model is generated by iterative modification or addition of units; when the information display result of the initial geometric model is consistent with the parameters determined based on the indoor environmental parameters and design requirements or meets the convergence conditions, the structure of the current initial geometric model is bidirectionally optimized and the bidirectional progressive topology optimization calculation is completed.

[0051] S4, importing the lightweight model into the modeling software, and performing secondary optimization, adding connecting parts or functional modules, adding a base or supporting parts to the lightweight model, and generating an organic furniture model;

[0052] Furthermore, in step S4, the secondary optimization includes optimizing the volume, evolution rate, filter radius, maximum number of iteration steps, and interval steps of the lightweight model.

[0053] Furthermore, volume optimization refers to the ratio of the volume of the optimized model to the volume of the original lightweight model, and its optimization target range is set between 20% and 55%; the evolution rate represents the percentage of volume material deleted each time during the iterative optimization process, and its optimization range is set between 1.5% and 3%; the filter radius is set to 1.5 to 2 times the grid size.

[0054] S5. Use 3D printing equipment to select linear materials, powder materials or liquid materials to physically manufacture the organic morphology furniture model to obtain physical organic morphology furniture.

[0055] Further, such as Figure 2 As shown, the organic furniture has two different forms: one-piece and assembled. The one-piece organic furniture is made by following steps S1 to S5, and the assembled organic furniture needs to add the following steps between steps S4 and S5:

[0063] Embodiment 1

[0064] Through the analysis of the bidirectional progressive topology optimization parametric leisure chair design case and the preliminary research on the hometown culture, Jiangmen was taken as the target, the architectural patterns or plant elements of Jiangmen city were extracted, the hometown cultural elements and parametric design cases were sorted out and summarized, the hometown elements were designed and diverged, and integrated into the leisure chair to produce a digital model. Then, the topological optimization algorithm of the modeling structure was calculated through the Grasshopper plug-in and Ameba tool in the Rhino modeling software, and the logical processing and optimized structure were generated. The leisure chair is more integrated into the Jiangmen region in terms of shape, and more lightweight and strong in terms of function. During this period, the structural optimization advantages of Ameba were used to perform high-quality meshing of the product model, visualize the model topology process, and optimize it later.

[0065] In terms of tools for topological parametric design practice, Grasshopper plug-in and Ameba tools in Rhino modeling software are mainly used to perform logical processing and construction optimization of modeling structures. The previous research on Ameba design-related processes has fully verified the structural design advantages of Ameba, which can not only perform high-quality meshing of product models in the early stage of design, but also visualize the intermediate process, and optimize the product after the later topology is completed.

[0066] In the practice of topological optimization design of leisure chair furniture based on Grasshopper technology and Ameba tools, the following design schemes were pre-set:

[0067] (1) Summary and analysis of preliminary research. Taking Jiangmen as an example, we analyze its location and surrounding environment, as well as the local cultural elements of Jiangmen. Finally, we extract the design scenarios, problem keywords and opportunity points.

[0068] (2) Extract the corresponding form. Based on the relevant elements of the overseas Chinese culture in the early stage, in the divergent thinking stage of design, the shape is extracted from the local architectural elements and the local unique natural elements to obtain the shape inspiration.

[0069] (3) Matching algorithm. After analyzing and extracting the selected architectural elements and the natural forms of the banyan tree, the model is simply initialized according to the characteristics of the two elements. Then, the Rhino model is used to model the basic human-computer relationship to obtain a digital basic model.

[0070] (4) Adjust the model topology parameters. The model is calculated through bidirectional progressive optimization, and then the load, support and non-design area settings are made for the product. The parameter design of the material to be landed in the later stage is selected and finally transmitted to the Ameba cloud platform for calculation.

[0071] (5) Modeling structure enhancement and appearance processing: After the product topology optimization is completed, the model is post-processed, the model is reconstructed and the four-sided mesh is re-topologically planned to obtain a high-quality mesh model.

[0072] (6) Complete the design of leisure chair furniture. Summarize the entire project process and provide a certain reference value for the construction of similar products in the future.

[0073] Pediment is the most western-style decorative part of the architecture of the hometown of overseas Chinese. It is located at the top of the building. The shape is often a dynamic "S" shape. The decoration is bold and varied, but it also retains the most basic mechanical and aesthetic principles. The shape is basically triangular, and the triangle is the most stable in mechanics. There are various pediment shapes, such as the most common isosceles triangle pediment, the dynamic bow pediment, the decorative scroll shape, and the scroll pediment. Taking the pediment as the starting point, the pediment elements of Jiangmen's characteristic architecture are extracted and applied to the design of the leisure chair.

[0074] After field investigations into the characteristics of the hometown's elements, based on the surveyed human-machine relationship and sitting ratio, the city chairs will be used as a carrier using the characteristics of parametric modeling and applied to the design, taking the outline of characteristic buildings as the entry point.

[0075] Setting the outdoor scene, according to the previous research, Ameba's design process is to perform topological calculations from a basic geometric model. The architecture of the hometown of overseas Chinese gives people a sense of stability and solidity. The pediment on the wall absorbs the influence of Western art and is unique and distinctive. Therefore, a flat oval appearance is set to meet the range of values ​​of the seat surface that meets the ergonomic sitting posture, and then the subsequent calculations are optimized to generate an organic structure.

[0076] As the design sketches continued to deepen, it was determined that the organic morphological structure of the banyan tree was similar to the optimized form of Ameba, and the application of design principles was further determined. The design was based on the premise of conforming to human-machine and satisfying people's rest comfort and convenient cleaning needs.

[0077] Grasshopper is used to conceive the torsional force of the product model support, and the calculated form is deduced to maintain the organic form, save unnecessary materials, and ensure the basic function of the product. The watchtower is used as the main prototype, and the backrest is designed with an arch shape to make the seat give tourists a sense of stability and firmness. As the hub of the overseas Chinese culture and one of the important plant patterns, the banyan tree also expresses stability and support. It is designed at the bottom of the seat, breaking the dull modeling language of the watchtower and adding a vibrant tree branch shape to make the product more integrated into the city.

[0078] The material setting of the leisure chair made in this embodiment uses the official default ABS plastic, and then the calculation target volume is set to 23%, and then the evolution rate is set to 2%, the filter radius is 0.15mm, and the maximum iteration step is 300. Connect to the Solver battery to upload the file to the Ameba cloud platform for calculation, and finally use the Render Display battery to view the topology process.

[0079] Ameba is based on the principle of bidirectional progressive optimization. The product is updated and iterated from the original seat model based on stress distribution. There are 95 iteration steps in total, and 5 is used as the intermediate value to record the change process of model iteration. The parameters are set as 23% volume fraction as the target and 2% as the purification rate. The final maximum equivalent force is 2.845MPA, and the maximum displacement value of the entire product is 2.66mm, which is a high-strength and organic one-piece shape. The product effect picture is as follows Figure 3 shown.

[0080] Embodiment 2

[0081] The relevant parameters of the production method are consistent with those in Example 1. In step S43, three slicing methods are used for product practice: the first is to reduce the product model by 1:10 for integrated model proofing; the second is to reduce the product model by 0.55 times and disassemble it into 7 parts for printing and assembly; the third is to print the product model at 1:1, and according to the maximum limit of the printer parameters of 256*256*256mm, the model is divided into 35 parts for slicing, printing and assembly. The product disassembly effect diagram is shown in the figure. Figures 4 to 9 shown.

[0082] Prepare assembly and polishing materials and devices, including PLA consumables, 10mm and 20mm iron pins, furniture putty, hot melt glue, hot melt gun, hair dryer, various grit sandpapers, silver paint and varnish.

[0083] First, arrange all the printed models, then connect and assemble the base support, and fix them with iron pins, hot air guns, hot melt adhesive, hair dryers and silicone sealant; then assemble the armrests and seat; finally, assemble the backrest as a whole.

[0084] The present invention, when used, comprises the following steps:

[0085] Step 1

[0093] Step 5

[0095] Step 6

[0096] Fence area demarcation: Fence areas are demarcated on the furniture surface to determine the laying range of 3D printing resin and reduce subsequent surface polishing work. The height and thickness of the fence are set parametrically to facilitate subsequent disassembly.

[0097] Step 7

[0098] 3D printing: Export the optimized model file to .STL format and perform 3D printing. Choose the appropriate material (such as PLA, resin or nylon) to ensure the accuracy and strength of the printed part.

[0099] Step 8

[0103] Step 10

[0104] Surface treatment: The furniture surface is ground and polished, and painted or textured as required to ensure that the final product meets the design requirements for beauty and comfort.

[0105] Step 11
