Industrial design and hand model

1. Design optimization Modern industrial design covers a wide range of content, ranging from paper clips and ballpoint pens to airplanes and ships, all of which contain the shadow of modern industrial design, but so many products have different design methods. Mechanical parts that emphasize geometric figures can be directly designed through computer graphics, and a certain degree of motion simulation experiments can also be carried out through the dynamics laws of computer 3D software. For some products with curved surfaces, such as small household appliances, on the one hand, it can be directly designed by computer; The value algorithm is used for smooth correction, and the 3D model data formed after correction can be used for hand model making. The advantage of this method is more obvious when designing works of art that focus on changes in curved surface shapes, because the appearance of works of art focuses on people's direct aesthetic feelings, and often has no rules to follow, and it is difficult to find regular geometric elements in it. Direct computer 3D drawing is half the effort. Even if the model is established, its follow-up modification is very poor. If it is the opposite, the shape designer will first directly use clay and other materials to shape the shape, and then use the 3D scanning equipment Parameterize the model, obtain the computer data of the original model, and then further process it through the prototype fast-speed model equipment, which can greatly improve the design efficiency. 2. Functional test The production of the prototype model can do certain functional tests, which can simulate the final form of the product, including functional form, curved surface form, etc., and use materials with a certain strength (such as ABS, PC, etc.) to manufacture products containing The functional prototype model of the internal structure is used to check whether the structure of the product is reasonable, whether the wall thickness meets the requirements, whether the moving parts are smooth, etc. You can also use the prototype model for aerodynamic testing. For example, in the design of high-speed moving objects such as automobiles, high-speed trains or spacecraft, a 1:1 model can be made and put into a wind tunnel for intuitive aerodynamic research. 3. Reduce costs A design defect that costs 1,000 yuan to make a model and inspect it may cause a huge loss of 10 million yuan if it is put into production and put into the market. In many cases, this problem is often fatal. The steady progress of the design process is very necessary, so it is very important to find defects in the product design process in the early stage of product design and correct them in time to avoid problems in subsequent production. Among them, model making is an important link that we can use. Through the production of the prototype model, the final shape, size, structure or color test of the product can be obtained at a relatively small cost, and important information such as product volume and quality can also be predicted, which has a great impact on the packaging cost, transportation cost and manufacturing consumption of the product. Raw material costs can be effectively controlled. And thus estimate the sales price and sales profit of the product. If the cost exceeds the assumption at the beginning of the design, it can be adjusted in time until the target range of the cost is reached. The production of prototype models is an effective means of cost control for enterprises. 4. Product confidentiality Product design is an important part of the company's core competitiveness. Products need to be kept strictly confidential during the design stage. The division of labor in modern manufacturing is becoming more and more detailed. The advantage of design outsourcing is that it can save the need to establish an independent company within the company. The cost required by the design agency also reduces the risk of product development, but it also brings difficulty in product confidentiality. Even if the enterprise establishes its own R&D agency, if the model stage still needs to be completed by an external design agency, there will still be design confidentiality issues. Therefore, large-scale manufacturing companies generally have their own independent R&D institutions and their own prototype model making equipment, so that the R&D process of new products can be completed independently within the corporate design team, reducing contact with external service agencies. Thus, the design data is guaranteed not to be leaked to the greatest extent, and the design secrets of the enterprise are protected. 5. Market research. Showing potential customers a plane display board or a 3D animation demonstration in a trade fair will not be more attractive than a prototype model. The simulation model can intuitively show the shape, color, size, and even the shape of the product. structure, function and other information. The production of prototype models is a convenient and fast initial performance of products. Different initial plans can be made into models, and market research can be conducted through exhibitions or actual verification by end customers. Fast, fast prototype technology can also be used in small batches. Copy the model, send the product model to different regions for investigation, and obtain more market-differentiating survey data. Prototype model technology can predict the actual psychological effects and usage effects of end consumers of products before mass production.
