Form follows function is a famous saying made by Louis Sullivan, the leader of the Chicago architectural school in the United States, when he summarized the design principles in 1907. The concept of form follows function was put forward in line with people's requirements for mass production, standardization and practicality of products under the conditions of large-scale industrial production. Moreover, due to the democratic characteristics of this concept itself, it was very important to Western countries who were struggling to find a new kind of product. For designers who wanted to innovate the outdated and backward decorative and eclectic design methods, it was undoubtedly a good medicine to realize their ideal of poverty alleviation and salvation through design. Therefore, it received widespread support and support from the industrial design community at that time. Since then, the modern industrial design movement with "form follows function" as its core has been in full swing in countries around the world.

The pursuit of the so-called form, which is simply the appearance, will definitely be eliminated in practice; while the pursuit of function reduces the cost of the product, making products such as cars, refrigerators, TVs, etc. that are originally expensive can Entering ordinary people's families is in line with the reality of production development after the industrial revolution, so it has developed rapidly. It can be said that "form follows function" is the basic feature of modernist design and the basis for our research and analysis of the development of modernist industrial design.

"Form follows function" is just a means to solve people's needs for basic living and production means in an era of material scarcity. It requires us to constantly update our concepts and learn with an open mind. The most important thing is to proceed from reality!
