The concept of Variable Method was earlier by Germany, which is important for innovative mechanical structure design. When using this design concept, you need to analyze the structure design concept of the product, reasonably determine the characteristics and requirements of the mechanical structure, and innovate design according to the actual situation, and effectively protect the quality of the mechanical structure, thereby achieving the design Effect. At this stage, the change information method is mainly to innovate the material, size, position, shape of the mechanical structure, and ensure the structure design effect.
2.1 material design
When mechanical structural design is performed, it is necessary to reasonably determine the design material, the nature, characteristics of each material, and different effects are produced when designing and construction. Therefore, the structural design should be optimized according to the actual situation of the material, thereby ensuring the design quality. For example, when the main body design material of the mechanical structure is steel, the advantage of the steel material should be given to a good hardness and intensity. In this regard, the method of increasing the size of the steel structure can be used to effectively improve its performance. Compared to steel, the hardness and strength of the cast iron material is different, and the traditional design concept has influenced its performance and cannot guarantee the quality and service life of the product. In the cast iron, it is also possible to effectively improve the performance of the mechanical structure. This variable can be designed to ensure the variables in the material structure, thereby ensuring the design effect [1].
2.2 Quantity Design
When designing the mechanical structure, it is necessary to adjust the number of internal elements to meet the needs of different industries. Normally, when innovative design is performed, only the number of internal elements of the structure can be changed, and the performance of the structure can be effectively changed to implement its design value. Although this design method is relatively simple, it can effectively protect the design effect. For example, in the screw design, the traditional design method is a gasket, a screw, a nut, and the like, the number of parts is large, and the installation of the mechanical structure has brought a lot of difficulty. In this regard, when innovative design, it can be designed to a multi-function integrated screw to reduce the number of parts used, thereby ensuring the efficiency.
3 Innovative design concept application advantages and problems needed
At this stage, in the development of science and technology, my country’s industrialization process has accelerated, but there is still a certain gap compared to developed countries. In this context, my country’s machinery manufacturing industry will lack international competitiveness and have affected their industry development. Under the new era, the market is increasingly focusing on innovative advantages and importance, which can effectively improve social productivity and achieve their economic benefits. At the same time, innovative mechanical structural design is conducive to optimizing design quality, so that it can develop in the direction of multi-functionality, and can effectively improve resource utilization and achieve their social benefits. In addition, the development of innovative design concepts enable companies to see their own development opportunities and challenges, which helps create a harmonious competitive environment, promote the rapid development of enterprises, and achieve their market competitiveness.
When designing the mechanical structure, you should pay attention to a few questions, one, optimize the design. When designing, a scientific approach is required to evaluate, which is beneficial to ensure the quality of the mechanical structure. At the same time, it should also be considered from two indicators of economic benefits and social benefits, and models the key structure sections, and the design is continuously optimized by comparison and analysis through data to improve design quality. The second is to strengthen the anti-corrosion design. Anti-corrosion design is more important, and the quality and service life of the mechanical structure will have a serious impact. Therefore, when designing, anti-corrosion design should be performed on the internal components, welding gap, member surface, etc., thereby ensuring the design effect.
