Research on Product Design for Improving Children's Sitting Posture Based on DEMATEL-ISM-TOPSIS Method
In order to scientifically correct children's poor sitting posture,enhance the user experience of sitting posture improvement products,and improve the fit of products with children at their peak growth and development,a product process integrating Decision-making Trial and Evaluation Laboratory(DEMATEL),Interpretive Structural Modeling(ISM),and TOPSIS method was proposed.First of all,with the help of Citespace software to sort out the research ideas of the products in this field,combined with the user's needs to summarize the influencing factor system of children's sitting posture improvement products,Second,a multilayer recursive structural model of the influencing factors was constructed based on the DEMATEL-ISM method to visualize the path of action among the factors.Finally,the carrier form is determined by the TOPSIS method,and the data collection accuracy is used as an entry point to improve the user suitability of the sitting posture improvement products and to complete the innovative design and optimization of children's sitting posture improvement products.The experiential and effective aspects of children's sitting posture improvement products are innovated,and the use of sensors makes the products applicable to children of different ages,which enhances the directionality of the user's needs and the design goals and further verifies the feasibility of the theoretical model of DEMATEL-ISM-TOPSIS,which can provide a referable idea for the innovative design of posture improvement products.
