Children have always been the focus of social concern.From the implementation of family planning in 1978 to the implementation of the second child policy in 2016,a new round of growth point of children’s products has reached a peak period,and the demand for children’s products and use has changed fundamentally.In the purchase and consumption of children’s products,the pyramid supply model has been formed from the original family expenditure of parents to the consumption form of several generations of parents supporting a child.At the same time,the two-way relationship between consumption and demand,and supply and products has formed a funnel-like supply-demand relationship.The increase in the use of children’s products has become a focus of attention in the design of children’s products.Looking at the current situation of children’s industry,there are some problems in children’s products,such as non recyclable materials,short service cycle and single function.The lack of practicability of products makes many products piled up and abandoned,and become "disposable" consumer products.The loss of these products in the production and processing and the idling of later articles largely cause the waste of resources,which is in line with the sustainable development theory of China Words are contrary to each other.How to achieve the combination of "human-machine-environment" consciousness in the innovative design of children’s products is exactly the purpose of this article to carry out the research on the sustainability of children’s products.For children’s products,the demand for personal use is far more than the real demand several times,and how to design these children’s products and reuse resources reasonably is the main content of this paper.To study the basic demand characteristics of children’s bathroom AIDS and carry out targeted research,to explore the key points and solutions of sustainable children’s products,strengthen the new use of sustainable children’s products,and expand the scope of use of products.Research and application of the concept of sustainability,hoping to improve the specific product design to achieve functional and life cycle extension.To explore how children’s needs and product use needs can achieve the same characteristics as hourglass.Through the investigation and integration of the advantages and disadvantages of children’s bathroom design and sustainable design of children’s bathroom,the main idea of sustainable design of children’s bathroom was proposed In terms of the utilization rate and extensibility of the product,the sustainable key points of the product are discussed from the aspects of material,function,process,scope of use and cycle.The integrated design is carried out for the demand change of auxiliary functions of bathroom in children’s growth stage,which further solves the problems of short service cycle and single function in children’s bathroom products,and guides the inheritance through product design Traditional culture,to achieve a virtuous and sustainable cycle of products. |
