The success of a 'company increasingly depends on the success of its products. An effective run of the development process is essential condition for obtaining successful products. In traditional, the term "product development" defines all the activities related to the planning, design, construction and marketing of the product. Following are the stages of product design and development:
1) The study phase.
The purpose of the development of new products, in order to meet the social and user needs. The user's requirements are the main basis for the development of new products selection decisions. This stage proposes the development of ideas and the overall program of new product ideas and new products principle, structure, function, materials and workmanship.
2) The idea of creative stage.
At this stage, according to the market demand as well as corporate social survey master their own conditions and take full account of the use of the user's requirements and competitor trends, has put forward the ideas and concepts of the development of new products. New product development creative idea emerges from three main areas. Firstly, from the user; Companies set out to develop a new product, the first to grasp the needs of users through a variety of channels, users in the process of using old products which improvements and new demand, and on this basis, the formation of new product development and creative. Secondly, from the enterprise workers; In particular, sales personnel and service technicians, regular contact with users, users of the old product improvements and demand change they are relatively clear. Finally, from professional researchers; researchers have rich professional theory and technical knowledge, to encourage them to carry forward in this area of expertise, and to provide the creative development of new products for the enterprise.
3) New product design stage.
Product design determine product design task book played to determine the product structure, until a series of technical preparation and management of the work, is an important part of product development, is the beginning of the production process , must strictly follow the "three-stage design" program.
The preliminary design stage
The main work of this stage is the preparation of the design task, so that a higher level of design task book reflect the product the reasonable design improvements and recommend observations, after the approval of higher authorities, technical design basis as new products.
The technical design phase
This is the technical design phase of new products shaping stage. It is on the basis of the preliminary design must test (new principle of structure, material component process function or mold test).
Working drawings and design stage.
The purpose of the working drawing design is completed for the trial on the basis of the technical design (production) and the random factory with all the working drawings and design documents.
4) New product trial and evaluation of identification stage
It is the purpose of assessing the quality of product design , test the product structure, performance and major process, verification and correction of design drawings, the basic shape of the product design ...
