Children’s Hospital Environment Design Based on AHP/QFD and Other Theoretical Models

Spatial environmental factors can effectively alleviate children’s fear of the medical environment when they seek medical treatment. This study focuses on the special environmental space of a children’s hospital, thoroughly considering the emotional needs of and the therapeutic effects on children as a unique group during medical treatment. By analyzing the existing design of children’s hospital environments, this research actively explores more suitable environmental design solutions for children’s healthcare settings. This study summarizes the user demand factors of children’s hospital environmental space design through field research and analysis interviews and calculates the weight indicators of user demand through AHP hierarchical analysis. On this basis, based on the QFD theoretical model, user needs are transformed into technical needs, and a house of quality is drawn to judge the conflicting needs through the positive and negative correlations between the factors. Finally, the forty invention principles of the TRIZ innovation theory are used to propose a solution to the environmental space program of children’s hospitals to obtain the optimal solution to the environmental space design effect. This study shows that incorporating theoretical models of AHP, QFD, and TRIZ into the environmental space design of children’s hospitals can improve and optimize the environmental space of children’s hospitals, and the example of a children’s hospital can be designed to meet children’s emotional needs according to this model. A series of interesting innovative practices, such as personalized digital information diagnosis and treatment, interesting visual guidance, and the implicit healing effect of color, can be realized. The aim is to create a modern, child-friendly medical environment that not only meets medical functional requirements but also effectively alleviates the stress of pediatric patients during diagnosis and treatment. This study preliminarily verifies the scientificity and rationality of the entire design process and provides a reference for the design practices of children’s hospital environments.
