Research on the Design of Public Space Seating for Pregnant Women Based on the Concept of Accessibility

With the continuous enhancement of society's awareness of caring for vulnerable groups, barrier-free design in public landscape spaces has gradually become an important part of urban humanized construction. Pregnant women, as a special group, face many physical and psychological pressures during outdoor activities. Their rest behavior puts forward higher requirements for the safety, comfort and emotional support of public space seats. This paper takes "public space seats for pregnant women" as the research object, based on relevant regulations such as the "Standards for the Construction of Barrier-Free Environments", combined with user behavior observation and questionnaire surveys, analyzes the differences in the needs of women in different pregnancy stages in terms of age, physiological state, psychological changes, body proportions and other dimensions, and extracts five groups of key data for comparative analysis. On this basis, the FBS design method is used to systematically construct from the perspectives of function, behavior and structure, and further combines the TRIZ inventive problem-solving theory to identify the contradictions and conflicts in the design and propose innovative solutions. Through case analysis and design verification, this paper finally proposes a set of public space seat design schemes for pregnant women that take into account functionality, safety and emotionality, in order to provide empirical value and theoretical significance for barrier-free and human-oriented design in urban public facilities.
