| Children are of great significance to the sustainable development of society and the inheritance of civilization.Its development status is an important factor in determining the quality of the population and social development in the future.The family’s main growth space for children has a great impact on children.The strategies and methods of expanding the space for green,economic and sustainable family activities which aim to small and medium-sized households as the mainstream of the market,and creating a ‘prepared environment’ for children,is of great significance both at the family level and at the social level.This paper mainly analyzes the relationship between children’s behavioral characteristics and family space environment through the analysis of children’s behavioral characteristics in the family environment,and then proposes a strategy to expand the activity space of small and medium-sized family children by using family ‘hidden space’.This paper is mainly divided into four parts.The first is to conduct a basic research on the behavioral characteristics of children in the family activity space from the theoretical aspect and practices,The research subjects are children aged 0-6 years old,which are divided into children aged 0-3 years old and children aged 3-6 years old.This aims to establish a basic pattern of children’s behavior,combined with field research to summarize the main behavioral characteristics of children in different ages "sensitive period".The second part will compare and analyze the current situation of space utilization of small and medium-sized family under the general perspective and children’s perspective,summarize the form preference of children’s behavioral characteristics from family activity space,and explore its spatial form and family space products from children’s behavioral characteristics.The connection of design has established the possibility of expanding the space for children in small and medium-sized families by using the ‘hidden space’ of the family.The third part combines specific design products and cases to analyze and smmarize the specific expansion strategies for children’s activity space and the design methods and principles of space products.In the process of children’s growth,the expansion of children’s activity space should be based on economically feasible conditions,adopting spatial change and sustainable design methods that can meet the needs of different family members.Finally,through the innovative design of children’s space products,it is verified that the family ‘hidden space’ is used to expand the feasibility of children’s activity space for small and medium-sized family.The purpose of this paper is from the perspective of children,to explore the behavioral characteristics and space requirements of the design objects with the behavioral characteristics of children in sensitive period,which helps to propose a green,economic and sustainable expansion of children’s activities for small and medium-sized families.Strategies and methods provide a suitable and stimulating environment for children’s development education and parent-child interaction,and at the same time guide the related products and space research in the same field. |
