Referring to the appearance design of intelligent incense machine, the application of automatic incense machine is very wide, suitable for hotels, hotels, hospitals, cinemas, bedrooms, shops and other densely populated or need to improve taste and add fragrance, let you enjoy the fresh air like nature.

That is, product design is an iterative process of "design-evaluation-redesign". In the whole life cycle of the product, the design finalize does not mean the end of the design work, as long as the product is still in production and sales, it will feedback a large number of user information and manufacturing information, and require the product to be constantly modified. Therefore, design permeates the entire life cycle of a product. Modern products should be designed with modern design methods, and should be product-oriented development and innovation.

Taking modern industrial products as an example, products have been developed from traditional mechanical products to electromechanical integration products, information electronic products, and the technological content has increased greatly; The function of the product is no longer the only factor for consumers to decide whether to buy the product. The innovation, agreeableness, environmental protection (green design) and appearance of the product are more and more valued, and gradually occupy an important position in the competition.

But for a long time, China's manufacturing industry is mainly oriented to processing, product development and strain capacity is poor, resulting in a single product variety, weak market competitiveness.

With the comprehensive integration of China's economy with the world economy, especially after China's accession to the WTO, domestic enterprises are facing huge challenges. The level of product research and development ability may determine whether enterprises can continue to survive. Therefore, modern product design method should be adopted to improve the design efficiency, shorten the design cycle, accelerate the replacement of products, and enhance the market competitiveness of products. Product design is a process of creative thinking and iterative optimization.

As a comprehensive embodiment of modern product design methods and means, computer-aided design technology plays an important role in product design.
