I just graduated in 2014 and worked as a design assistant in a range hood electrical company to help engineers. Three months of internship production line assembly products, screw assembly, etc., to understand the product parts. In-depth knowledge of sheet metal, processing technology (grinding and polishing, stamping, bending, welding (argon arc welding, spot welding, full welding), laser wire cutting, spraying process, printing process (silk screen, thermal transfer, UV printing, pad printing, laser engraving, etc.) sheet metal (304#,430#) cold plate, galvanized parts. Tempered glass thickness, lamp (led, halogen lamp), relationship between motor air output and negative pressure, etc.).
Relatively speaking, the enterprise product is more single, more specialized in the field. Enterprises can have a more comprehensive understanding of the product from "nothing to have" breeding process, consider more comprehensive knowledge, products more in line with market demand.
The university teacher said that design really does not make money! Behind the verification design really does not make money! The biggest advantage of design is that it gives us the thinking to solve problems, which is the biggest advantage of design.
