First, the word "design" is almost one of the most fashionable words in modern society. In engineering and visual arts, people often use the term "design". Such as architectural design, industrial design, screen design, programming and so on. Design activity is an important human activity. It is generally believed that design is an inquiry activity aimed at conceiving and realizing new things with practical value. This is a process guided by goals, and the purpose of this process is to create new things. In order to grasp the essence of design activities, we must also consider design activities in the context of human understanding and practice.

Second, the essence of art design;

1. First of all, design is abstraction and creation. Design is to transform our demand for products in the real world into specific product functions. Design is an important bridge between requirement and realization. Demand is in the real world and realized in the abstract field, so design is the key to link reality and abstraction. I emphasize that design is abstract, based on the idea of product development, extracting the value of * * * and abstracting it into the function of the product. From this point of view, completely conforming to the definition of design is a purposeful creative behavior. All kinds of design drawings and formal drawings we are talking about are abstract ways to show design.

2. Secondly, the design is to meet the demand and solve the problem. The most basic design is to meet the demand, which can be used value or ornamental value. The further view of design is to enhance demand, that is, to enhance the use value and convenience of products through effective and reasonable design. For example, user engineering, industrial design, interactive design in software and so on. The highest level of design is to lead demand, that is, to lead consumer demand through forward-looking design. In this regard, Jobs' ipad and iphone are good examples of forward-looking design.

3. The final design is a scheme balance. As mentioned above, design is more about meeting the needs of end customers and solving the problems faced by customers, but for product design, it must also rely on other non-functional needs, that is, whether the maintenance and upgrading of the product itself are convenient and whether the raw material composition of the design itself is universal to help reduce costs. Therefore, design is a comprehensive balance of environment, inside and outside, personnel, cost, market, communication and demand. Don't want the optimal solution, but need a satisfactory solution.
