What Are the Different Types of Modular Structures?

Modular design, simply put, is that the writing of the program is not to enter computer statements and instructions one by one at the beginning, but first to describe the main structure and flow of the software using the main program, subroutine, subroutine and other frameworks, and define and debug Input and output link relationships between various frameworks. The result of stepwise refinement is a series of algorithm descriptions in functional block units. The method of programming a function block as a unit, and implementing its solution algorithm is called modularization. The purpose of modularization is to reduce the complexity of the program and simplify the operations of program design, debugging, and maintenance. To change a sub-function, just change the corresponding module accordingly.

Modular design

Modular design simply means that the writing of the program is not to enter computer statements and instructions one by one at the beginning, but first use the main program,

(Modular design) The so-called modular design is simply to combine certain elements of the product together to form a subsystem with specific functions, and use this subsystem as a universal module to combine with other product elements , Forming a new system, producing a variety of different functions or series of products with the same function and different performance. The modular design is

Modular design refers to dividing and designing a series of functional modules based on a functional analysis of different functions within a certain range or products with the same functions and different performances and different specifications, and the selection and combination of modules can form different products Design method to meet the different needs of the market.

Strive to compose as many products as possible with a small number of modules, and on the basis of meeting the requirements, make the products with high accuracy, stable performance, simple structure, and low cost, and the connection between modules is as simple as possible;

Modular

Modular products are an effective way to achieve the goal of single-piece production with the benefits of large batches. Product modularity is also an effective way to support users to design their own products. Product modules are standard components with independent functions and inputs and outputs. The components here generally include sub-components, assemblies and parts. Modular

(I) Contribution to Enterprise Product Development

Because modularization promotes the speed of innovation, business leaders 'response time to competitors' actions is greatly reduced. As a rule, managers have to adapt more

Modularity is a new design idea developed on the basis of traditional design. It has become a new technology and is widely used. Especially in the information age, electronic products are constantly being introduced. Modular design products are constantly emerging. How to make the product's modular design meet the diversified needs of the market in an all-round way should attract great attention from business operators, new product developers and their standardization researchers. Modular design has been widely used in design fields such as machine tools, electronic products, aerospace, and aeronautics, but so far, the modular term has not given a recognized authoritative definition. On the one hand, companies must use batches, standardization and generalization of products to shorten the time to market, reduce product costs, and improve product quality. . In this way, how to balance the contradictions between standardization, generalization, customization, and flexibility of products, and become the winning competition

In order to develop different products with multiple functions, it is not necessary to design each product individually, but a variety of modules are carefully designed, and they are combined in different ways to form different products to solve product varieties, specifications, and design and manufacture. The contradiction between cycle and cost is the meaning of modular design. Modular design is closely related to standardized product design and serialized design, which is the so-called "three modernizations". "Three modernizations" affect each other and restrict each other. They are usually used together as an important indicator to evaluate the quality of products. Modernization principles have been used in machine tool design. By the 1950s, some countries in Europe and the United States formally proposed the concept of " modular design " , The modular design is raised to the theoretical height to study. The idea of modular design has penetrated into many fields, such as machine tools, reducers, appliances, computers, and so on. In each area, modular and modular design have their specific meanings.

Module: A group of units that have the same function and joint elements (referring to the shape, size, and fit or mesh between joints, etc.), but can be interchanged with different performance, specifications, or structures.

Modular design machinery products

Bed clamps and couplings can be called modules, and some parts such as plugs and sockets can also be called modules in a broad sense, but it is better to call them standard parts. In the modular design, a large number of standard parts are also used, but the module refers to the units outside the standard parts that still need to be designed and can be used in different combinations to form equipment with different functions.

Modular design: Based on market prediction and functional analysis of the product, a series of general functional modules are divided and designed; according to the requirements of the user, these modules can be selected and combined to form different functions or the same functions But products with different performance and different specifications. This design method is called modular design.

The main way of modular design

1) Modular design of horizontal series. Do not change the main parameters of the product, use modules to develop deformed products. This method is easy to implement and has the widest application. Modules are often replaced or added to the base type to form a new deformed type. For example, when replacing the milling head of an end face milling machine, an end milling head, a horizontal milling head, and a turret milling head can be added to form a vertical milling machine, a horizontal milling machine, or a turret milling machine.

2) Vertical series modular design. Design basic products of different specifications in the same type. Different main parameters, dynamic parameters are often different, resulting in different structural forms and sizes, so the modular design of the horizontal series is more complicated. If the components related to the dynamic parameters are designed into the same universal module, it will inevitably result in lack or redundancy of strength or stiffness, which will affect the function, and redundancy will cause a huge structure and waste of materials. Therefore, in the design of modules related to dynamic parameters, the sections are usually reasonably divided, and the modules are only used in the same section; for modules that are not related to power or size, they can be used in a larger range.

3) Horizontal series and cross series modular design. In addition to the development of horizontal series products, those who change some modules and obtain other series of products, belong to the horizontal series and cross-series modular design. The modular boring and milling machine produced by the German Sachmann Machine Tool Plant can develop horizontal series of NC and various types of boring and milling machining centers, and replace the column, slide and table to change the boring and milling machine to a series of floor-type boring machines.

4) Full range of modular design. The full range includes vertical and horizontal series. For example, a tool mill produced by a German factory can be changed into end mills, horizontal mill heads, turret mill heads, etc. to form horizontal series products, and the height and length of the bed and beam can be changed to obtain three vertical series product.

5) Modular design of full series and cross series. It is mainly used for the modular design of cross-products with similar structures on the basis of the entire series. For example, the entire series of gantry milling machines have a structure similar to that of gantry planers, gantry planers, and gantry rail grinders, and can develop cross-series modular designs.

Modular design, a new design concept and design method, is rapidly being widely used in various fields. Its competitive advantages are mainly reflected in two aspects: on the one hand, it resolves the contradiction between variety and specification diversification and professional production; The aspect also creates the necessary conditions for advanced manufacturing technology and improved equipment utilization, to provide products with customer satisfaction in different batches, and thus to enable enterprises to achieve product diversification and unified benefits.

The purpose of modularity is efficiency. Its intent and ultimate purpose is to meet people's diversified needs and adapt to fierce market competition, to achieve the best efficiency and quality under the multi-variety, small-batch production mode. The object of modularization is the composition of a product or system. Modularity does not study and solve the problem of the design or composition of an isolated product or system. Combination of modules. Because the object of modularization is a system, the principles and methods of system engineering are the basic principles of modularization. The main method of modularization is the decomposition and combination of systems. Modular products or systems are composed of standard modules. How modules are produced, whether they can be effectively combined into a product or system, and the skills and application level of product and system decomposition and combination are the core issues of modularity. The goal of modularity is to establish a modular system and an object system. There are two goals or products of modular activities, namely forming a modular system and a modular product system. Establishing a modular system is the premise of implementing a modular design, and forming a modular product or system is the ultimate destination of modularity.
