Abstract

The invention provides a vehicle body combination function design method integrating Kano, QFD and FAST. The method comprises the following steps: firstly, collecting user demands, hierarchically analyzing the user demands by utilizing a KJ method, classifying user demand attributes in combination with a Kano model, and determining importance; secondly, decomposing a vehicle body function by adopting a FAST method to obtain a vehicle body function structure; and finally, according to the user demand data, importing the vehicle body function structure into the demand-function quality house model, establishing a matching relationship between the user demand and the vehicle body function, and forming a vehicle body function system diagram. According to the baby carriage function design method, Kano, QFD and FAST methods are integrated, effectiveness and reasonability of the method are verified through design practice of the baby carriage, reasonable functions can be effectively explored from the perspective of user requirements, and the optimal design scheme is obtained in a combination mode.

Description

technical field [0001] The invention relates to a combined function design method of a car body integrating Kano, QFD and FAST, in particular to a combined design method of a stroller, belonging to the technical field of stroller design. Background technique [0002] With the development of economy and society, people's demand for travel is becoming more and more important, and the requirements for travel tools are also getting higher and higher. In baby car body design activities, function is the most important essence of the car body, which also means that product designers need to have a deep understanding of market conditions and user needs. The core of stroller body design is to meet the needs of users. However, the needs of users are constantly changing with the development of society and the progress of the times. The design methods of the prior art are difficult to meet the needs of current customers. Contents of the invention [0003] Mining the potential needs o...
