3.1 The impact of design concept

   In 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 follow-up 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 "people-oriented" 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 common 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 macro-environment 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 comprehensive optimization of the industrial design of a new concept.

3.2 The impact of design style

  Simple 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 in-depth， specific， practical significance.

  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.

3.3 The impact of design method

  The impact of the “3r” principle and under the guidance of the implementation of green design methods are： modular design， removable design， recyclable design， long-life design.

  Modular 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 combination 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 components， once the end-of-life products， they can re-use or recycling； Third， improve the repair of products can extend the life of the product.
