ABSTRACT：Objective：to study the design of Children's bicycle，in order to provide new innovative ideas for the design of children's articles. Methods，through the analysis and comparison of the current situation of running products at home and abroad，from the point of view of product innovation，children's physiology and psychology were summarized，and the deficiencies of Children's bicycles were analyzed. Conclusion，the sustainable design of Children's car is put forward，which provides a new innovative direction for the future design of children's car.

Key words：open to traffic，product design，sustainable

The total number of children in China has exceeded 201 million，according to the National Bureau of Statistics of the People's Republic of China. Children's means of transportation，in a narrow sense，is designed according to the size of children's bicycles. However，there are also many child-friendly tools on the market that can not be described as bicycles，such as torsion bikes，tricycles / four-wheeler，transportable bicycles and scooters. In a broad sense，the vehicle tools used by children are different from the concept of bicycle，which can not be called "baby carriage" . Therefore，according to its functional characteristics，from the design point of view，it is more reasonable to call it the children's entertainment transportation tool 2. At present，problems such as over-decoration，function superimposition and inferior materials in the market of baby carriages are still common. The existence of these problems is an obstacle to the positive development of the design trend，the aim of this project is to provide a sustainable design concept to improve product utilization and life cycle.

一、Design，research and analysis

Through detailed market research and relevant data collection，according to the current situation of children's car at home and abroad，combined with professional knowledge and related data analysis of the existing children's car innovative design. The children's car I designed is not only beautiful in appearance，but also functional and can meet the aesthetic needs of most children. The design concept of simplification，functionalization，safety，easy operation and people-oriented is embodied in the design of the products. Further research is carried out in the aspects of product structure，shape，application of new materials and process effect，the function，safety and life cycle of the children's car are strengthened，and the product design is optimized. At the same time，the children's car is developed to meet the growing needs of children. Design is to improve the quality of life，people-oriented，so to do a suitable design，in line with consumer psychology design，only in this way can let consumers accept your design. User demand analysis is the cut-in point of product design 3，only master the demand can accurately grasp the design direction.

二、Design pain point analysis

Article 1：The Children's cars sold on the market are relatively simple in function and do not have conformity，only considering the use of children in a single environment，and the applicable age distribution is relatively small. Second：Some do not take into account the age of the child's intellectual and physical development，the development of children's intelligence and ability to participate in the operation of no solution. Third：expensive，single function does not have a long life cycle，which leads to the age of the increase in costs. Fourth：The appearance is too exaggerated，easy to children's health aesthetic adverse effects.

The main problems of the children's cars on the market are short life cycle，single function，poor integration and high cost of purchase. In the face of these problems，we need the appearance，function，color and sustainability，through scientific，rigorous and innovative design，we can change the current situation of the products in the market.

三、Product Analysis

Color and shape are another form of design expression language，the children's world is colorful，is full of curiosity，for children more bright colors such as orange，yellow more easily attracted their eyes. Therefore，the choice of children's car on the color of yellow and silver，color and shape to meet the public aesthetic trend of the mainstream，white and yellow with the product reflects the concise and generous modernization. White is an inclusive color，giving a feeling of cleanliness，comfort，soft，yellow is a comparison jump color，give a person a visual impact，the combination of white and yellow has the overall beauty，as well as the details of the dance.

With the progress of society，People's aesthetic level is also improving，now people more and more like simple and generous style，natural and elegant streamline style more and more become people's aesthetic new favorite，join a round geometric symbol in streamline，it makes the whole thing look like it's jumping and it's not falling apart. The combination of the cuboid and the cylinder makes the operation more obvious. BIONIC "Mantis" arm as a handlebar add some vitality and vitality，as if in nature galloping general.

四、Conclusion

On the premise of providing a more comfortable and safe baby carriage for children，in the aspects of appearance，function，color，material，man-machine and manufacturing technology of children's cars，we can deeply understand the real needs of children through scientific investigation and research，and optimize the function and value practicality of the products，the utility model is the foundation of the multifunctional children's car to realize the thorough life. Children's car market prospects are broad，I believe that my design of multi-functional children's car will be truly popular.
