【正文】 e resources of the means of its reprocessing of raw materials can be reused or product， put it back on consumption. Resources of the socalled class of resources usually include the original and secondary resources. The original class of resources is the waste of resources after the formation of the same with the original products， subresource is the waste of resources into different types of after the new products. To promote waste recycling economy will be the source of the original and subclass of bining resources in order to fully realize the recycling use of resources.3. The impact of the “3r” principle of to industrial designIn modern industrial economy， the product design is often to serve the people， just from the people to meet needs and solve the problem as the starting point， and do not consider the followup products， use of resources and energy consumption and emissions on the environment and other ecological problems. “3r” principle in the design concept under the influence from the peopleoriented towards the harmony between man and nature of green design， while respecting the needs of people， but also consider the safety of the ecosystem. Cycle economic model of the industrial design under the design concept， put people and nature live in harmony and mon development in the first place， the use of systems theory and Calibration of all acts of industrial design， from product design at the beginning of the macroenvironment had priority to consider and pay attention to the coordination of products that run the various elements of the process in order to achieve system optimization. Here， the environmental factors are the starting point of the whole design and end points， through the design， efforts to improve and reduce the products in the production， use， recycling process， such as the adverse impact of the environment. So Green Design Products are in the harmony between man and nature under the guidance of thought to the harmonious development of man and nature， the principle of human machine system one considers the environment， a prehensive optimization of the industrial design of a new concept. The impact of design styleSimple is an aesthetic pursuit of extremists on the design of easy style， popular in the 20th century， in the United States age 80. If we say that in the industrial economic model， the simple style of product design aesthetic is a subjective pursuit of people， then in the recycling economy mode， the structure of the simplest and most parsimonious of the materials， the most beautiful modeling， the most pristine appearance simplicity of product design， sustainable development concept is a concrete manifestation. “3r” Products doctrine of the meaning of this simple style more indepth， specific， practical significance.The impact of the “3r” principle and under the guidance of the implementation of green design methods are： modular design， removable design， recyclable design， longlife design.Product design is removable at the design stage， so that parts of the Products has a good performance of the demolition. Conducive to the reuse of ponents or recycled materials to save not only protect the environment and Materials. The demolition of the design requirements， Product First， connect the various parts and ponents， as far as possible the use of detachable connection， such as threaded connections， unified type fasteners， reducing the number of fasteners， try not to use welding， riveting， bonding and other nonremovable the connection； Second， in the selection and processing of raw materials， the demolition of the connection； to use and reuse of recyclable materials， the types of materials， such as less as possible.“3r” principle in guidance and norms， product design， material selection should be taken into consideration： First of all， minimize the use of materials. Try using high quality materials to enhance the service life of products； the prohibition of the use of contaminated material against big， look for the corresponding sound material substitution； Reuse as much as possible the use of recyclable materials. Secondly， the preferred sound of the ecological environment of the material， after the preferred deposition of waste and the natural world to absorb the material， preferred low power， low cost， lowpolluting materials， preferred easy processing， and processing of nonpolluting or less polluting materials， preferred materials recycling. Finally， to reduce the use of the types of materials in order to reduce the cost of Recycling Materials； maintain original material， as far as possible the use of simple materials， the use of alloy materials， to avoi
