Research on the design of growable solid wood children’s beds

Abstract

To meet children’s needs for beds at different stages of growth, a product design model integrating the KANO Model, the Hierarchical Analysis Method, and Axiomatic Design (KANO-AHP-AD) was adopted to conduct a design study on the growability of solid wood children’s beds. In accordance with the KANO model, the demands for children’s beds coming from questionnaires among families with children were classified and sorted, and the demand indicators were then summarized. Secondly, AHP was introduced to establish a multilevel hierarchical model, construct a judgment matrix of design elements, and calculate the weights of these elements to improve the accuracy of users’ demand weights. Then, AD was used to complete the mapping of the demand domain, function domain, and design domain of children’s beds and to judge their reasonableness through the matrix. Such a design allows users to evaluate and verify the rationality of the program. Through modular design techniques, the growability requirements were fulfilled. A low number of product modules were freely combined to form product types with multiple functions to meet customers’ needs for personalization and functional diversification. The work has value for the design of growable children’s beds, thus contributing to sustainable development and environmental protection causes.
