How to break through the ability of product structure design engineers?

Product structural designer refers to a senior engineer who is engaged in designing the specifications, functions and appearance of products according to the requirements of customers. Rational design of the internal and external structure of the product, so as to ensure that the product is developed in the shortest time, the lowest cost and the highest quality.

The main skills that a product structural designer needs to possess include:

1. Basic knowledge of mechanical design;

2. Proficient in the design of plastic parts, sheet metal and die-casting; i.e. design for manufacturing; Ensure that the part design is simple, the quality is high, the defects are few, the manufacturing cost is low, and the corresponding mold structure is simple, and the mold manufacturing and processing are easy.

3. Proficient in product assembly and design skills; i.e. assembly-oriented design; The assembly of the product is as important as the manufacture of the product, and the assembly of the product should make the assembly process simple, the assembly efficiency is high, the assembly defects are few, the assembly cost is low and the assembly quality is high; Commonly used assembly design guidelines include reducing the number of parts, simplifying product structure, standardization of parts, product modularization, designing stable bases, design-oriented features, positioning parts before fixing, error-proof design, ergonomic design, etc. For detailed guidance, please refer to the "Product Design Guide for Manufacturing and Assembly" published by the China Machine Press. The book also includes plastic parts design guides, sheet metal parts design guidelines, die casting design guidelines, tolerance analysis, etc.; Proficiency in these design guidelines ensures that product design is carried out in the shortest possible time, at the lowest cost, and with the highest quality.

4. Master the knowledge of tolerance analysis; Able to use tolerance analysis to optimize product design quality and solve practical problems encountered in product development;

5. Familiar with relevant materials, molds and surface treatment processes;

6. Have the ability to analyze and solve problems; There are inevitably many problems that will arise in product development, and the ability to analyze and solve problems is crucial.

7. Familiar with the product development process, especially the product development process for manufacturing and assembly, a good product development process can help product structure engineers reduce design changes, shorten product development time and improve product development quality;

8. Familiar with relevant product testing requirements, such as EMI, ESD, safety and reliability, etc., and design products to meet these requirements;

9. Familiar with relevant product industry standards;

D and 2D software knowledge, commonly used 3D software including PRO E, UG, SOLIDWORKS, CATIA, etc., proficient in one of them; Commonly used 2D software is AutoCAD;

11. Good spirit of innovation; You can learn the theory of TRIZ.

12. Team spirit; The success of product development is inseparable from the cooperation of the team, the product structure engineer cannot fully grasp the knowledge of product manufacturing and assembly, testing, etc., the product engineer should be able to improve the quality of product development by working with the team of manufacturing engineers, assembly engineers and test engineers.

Do more projects, the so-called can make perfect, contact more projects, and grow slowly. There are many needs on the ZBJ.com that can be undertaken.

To become a qualified product structural engineer, you need to have the following:

1.Skills: It is a tool for eating, which must be mastered. We will design a reasonable structure according to the appearance of the parts.

2.Knowledge: materials, safety regulations, molds, processes, etc.

3.Communication: Mold trial, mold follow-up, ERP, SOP, BOM understanding, etc.

4.Ability: the ability to analyze and solve problems, the ability to integrate resources, etc.

As a product structure stool design, there are many things to understand, and you need to work for a long time to accumulate. "Design Notes"The online provides a lot of structural design materials before the good Jane, as well as the source files of PROE, hoping to help some engineers who need to learn the structure of the dust brigade.

Design the structure of the product, make the product easy to process, and let the product meet the customer's requirements (function).

Product structure design engineer is a kind of engineer responsible for product design, which belongs to the category of industrial design, and other product function design, performance design, etc., belongs to the front end of product research and development, and has high requirements for technology and industry understanding.

The general responsibilities are as follows, and may be shared by several product structural design engineers:

1) Responsible for the design and development of the company's new product structure design work, so that the designed product structure not only meets the industrial design standards, is convenient for processing and production, but also can meet the product function and performance requirements, preferably beautiful, generous, and promote consumers to buy;

2) Combined with the product structure design, formulate the manufacturing process specifications and quality standards of the products.

3) Customized product structure, need to design and develop product custom molds at the same time.

Generally, it is required to be proficient in the use of design software such as Auto CAD, PRO E, CAD, Soildworks and other two-dimensional or three-dimensional design software.
