Redesign are able to make the best of 3R in the extension of the field of industrial design and development, is a matter of deep study and practice the new task, it should be, together with the 3R principle, bee a model of circular economy are industrial 4R principles of design. As the international chairman of the Federation of Societies of Industrial Design, Mr. Peter said the design of human development as an important factor, with the exception of selfdestruction might be the ruin of mankind, human arrival may also bee a shortcut to a better world. Today, in the framework of national sustainable development strategies, the role of industrial design is changing, and actively looking for a new direction for the development of circular economy at all levels play a role. Industrial design will bee a powerful for cycling of our country economic. 譯文成績 （百分制） ： 指導教師簽名： 年 月 日 備注： 英文原文出處包括出版社、出版時間、期刊的刊名、刊號、刊期。 maintain original material, as far as possible the use of simple materials, the use of alloy materials, to avoid material harm to the environment of the surface treatment。 the prohibition of the use of contaminated material against big, look for the corresponding sound material substitution。 Second, products are easy to repair and maintenance。 Second, in the selection and processing of raw materials, the demolition of the connection。 Second, it will be able to be easy to use or duplicate the functions of independent recovery, enhance the versatility of the ponents, once the endoflife products, they can reuse or recycling。 Fifth, the structure of simple, easy to create。 Second, to promote. Small is beautiful . Less Is More, the lightweight and pleasant form of products. Third, the design features of the object collation, evaluation, definition, must always focus on the merger, to simplify, optimize, and makes the core functions briefly products。 In the consumer area, reduction of the supremacy of the principle of a change in consumer lifestyles and advocate moderate consumption and green consumption. Reuse principle is the second principle of circular economy, that is, process control methods, with the aim to improve the products and resources use efficiency, it calls for product design to initial the form of packaging for multiple items to prevent premature bee waste. In the design, to the use of standardsized parts, repair and upgrade in order to replace, thus prolonging the service life of products。s economic construction . However, along with the traditional industrial design creating highquality modern lifestyle and living environment and promoting economic development ,it also speeds up the consumption of resources and energy. What’s more ,it dose harm to the ecological balance of the Earth and brings about a serious of great damage to human survival and sustainable development. Especially the excessive mercialization of industrial design, utilitarian and excessive pursuit of profit, the implementation of merchandise has plans to abolish the system without taking into account production, use, process waste, such as the environment, the impact of resources. It can be said that people are in inappropriate and excessive consumption patterns of life, the industrial design objectively bees essential medium to encourage people to uncontrolled consume, which is countered to the essence of industrial design—creating a science and healthy way of life. Facing the threat of human survival and sustainable development, in the 20th century, people began to question the sustainable development of humanity ,to carry out a profound reflection on sustainable development and to put forward a suitable model of circular economy , the principle of circular economy is 3R (ie Reduce, Reuse, Recycle) which is of great significance to the implementation and promotion of socioeconomic stability, sustainable development Against this background, the concept of sustainable development into rapid economic development is inextricably linked to the design, based on this ongoing exploration and practice. 3R principles intended to sort out this article on various aspects of industrial design and the guiding role, and attempts to explore the 3R principles of industrial design at the extension. 2 Cycle economic model and the principle of 3R Economy
