| The superposition design technique has been widely applied in the design of products,and it has become a trend in the design field. Then what value will superimposed effect bring to the design of commercial space? With the advent of virtual era and the development of "imaging technology" in the space sector, the "crossover" culture has gradually blurred the "boundary" and extended the "domain", which brings about numerous design forms. Being one of them, the superimposed effect can also play an important role in commercial space.The superposition design technique is not a simple combination of function and form, which is introduced in the paper. And this paper makes an analysis about the application of superimposed effect in different types of commercial space, summarizes the design technique,the way of thinking and the law of superimposed effect, and also expounds the significance of superposition of elements such as form, emotion, culture, function, technology, material and subject. The development of anything may become a double-edged sword, and not all superposition can lead to good effect. Therefore, this paper also analyzes how the output of "false" superimposed effect does harm to the production and people’s life, and puts forward solutions.The application of design technique of superposition in commercial space design has exerted an influence on the production and people ’ s life, and will necessarily become a design trend. |
