Specifically include the following： First， improving product reliability and durability； Second， products are easy to repair and maintenance； Third，using standard， modular product structure The impact of design materialModular design is at a certain range of different functions or different functions the same performance， different specifications of the products on the basis of functional analysis， and design into a series of functional modules， through the selection and bination of modules can constitute different products to designed to meet the different needs of the Ways. The benefits of modular design： First， make products with good performance Recycling demolition， settled design different types of products and waste of resources； 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； Third， improve the repair of products can extend the life of the product.First， the premise of ensuring the functionality as far as choice of materials can be recycled， such as biological materials， so less material on refined， appropriate； 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； Fourth， the product is intended to be simple and clear language； Fifth， the structure of simple， easy to create； Sixth， the choice of degradable material， the structure of easy solutions， such as withholding together. The impact of design method“3r” principle is not only on products from the design， production， sales， use， disposal and so on throughout the life cycle have an impact on all aspect， but also on the industrial design itself， a more extensive and profound changes： The impact of design conceptReduction principle is the first principle of circular economy， that is the source of control method， which requires the source of economic activity the design stage， pay attention to the use of resourcessaving and pollution reduction requirements with fewer resources to achieve the established purpose of the production or consumption In the production areas， usually the energysaving production processes， materials and conservation of resources， the products of small size and lightweight， and easy and simple packaging requirements in order to achieve the purpose of reducing waste emissions； 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； In the consumer area， to promote the purchase of durable consumer goods， to reduce the use of disposable products， such as aftersales service by strengthening the means to extend the product life as possible and not waste.Circular economy development pattern is from one of resources of renewable resources， one of green products posed by the material energy of the closedloop feedback loop process， this closed loop system， can maintain economic production of low， highquality， lowwaste， which will be economic activity of natural resources and environmental impacts to minimize damage. Interpretation of the circular economy mode “3r” principleHuman survival and economic activities rely on the resources and the environment. On one hand ，it is the source of the human beings material system； on the other hand， it bears the economic activities of human waste generated by the various roles. The Earth can provide resources but are limited， even though it must have the ability to purify， however it is subject to human economic activity the ability of emissions is also limited.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” (. Reduce， Reuse， Recycle) which is of great significance to the implementation and promotion of socioeconomic stability， s
