Application Of QFD And TRIZ Integrated In A Children’s Toy Car In The Conceptual Design(with A Scooter As An Example)

The children’s toys dustry in China started in the 1980 s,the rapid economic development of our country after reform and opening up,as labor-intensive children toy industry has obtained certain achievement.The rising status of children group in the family and society,children and parents’ demand for children’s toys have be strengthened year by year.So all kinds of children’s toys appeared on the market.Children’s scooter of the moveable and flexible has been loved by children and parents in many children’s toys.Research on children’s scooters and analyzed the type and the market development of children’s scooter.The enterprise of children’s scooters must constantly to improve the innovation of product for success in the fierce market competition.The basic phase of concept design determined the quality and cost in the product life cycle.So the main stage of product innovation lies in the concept design.So design theory of integration in product innovation has important practical significance in this stage.Research on QFD and TRIZ integrated in the conceptual design for children’s scooters.QFD is English acronyms of quality function deployment.It is a method of product design and planning.It driven by customer needs and put the house of quality as a technical innovation tools. At the same time TRIZ is Russian acronym of invention of problem solving.It is an innovative method.It takes the technology evolution theory as the core and takes the contradiction matrix and invention principle and so on as the tools of analysis problem and solve problem.Now integration the QFD and TRIZ to constructed concept design model.And with the children’s scooter as an example to verify the feasibility and validity of the model.Research on QFD and TRIZ integrated in the conceptual design for children’s scooters.Through a variety of market research get the original information of customer demand.Based on the affinity diagram method for organizing the information.Using the decision tree to classify and forecast information of customer demand.By tools about house of quality from QFD to build relationship between customer requirements and technical characteristic matrix.Through analysis the weight ratio and the degree of relationship of comparison matrix to determine the positive correlation and negative correlation.Later analyze and solve the problem use of TRIZ tools. Finally successfully designed a children’s scooter of flexible and environmental.It verified the feasibility of the conceptual design model.This model can guide the manufacturing enterprise and improve the ability of enterprise product innovation design.In a word,this research has important theoretical significance and practical significance.
