• Recycling waste is one of the main methods of sustainable design concept, which can reduce resource consumption and thus create eco-friendly products. Traditional green design has focused on the recycling of waste and the extension of the life cycle of product materials. Some scholars also consider emotional Customer Requirements (CRs) in eco-friendly products, but prioritize appearance over environmental function innovation. The rapid development of internet technology has enabled the proliferation of online product reviews, which can be analyzed to inform eco-innovative product design that meets CRs. Based on the CRs extracted from online reviews, this paper proposes an eco-innovative product design method that aims to recycle waste and meet emotional CRs. Firstly, online reviews are extracted using Latent Dirichlet Allocation (LDA), and CRs for environmental protection functions, appearance, human-computer interaction, and service experience are summarized by integrating sustainable design concepts and emotional design theories. Secondly, the Theory of Inventive Problem Solving (TRIZ) is utilized to suggest targeted solutions for core CRs, innovating product function modules and usage. Thirdly, the combination of Kansei Engineering (KE) and the Interactive Genetic Algorithm (IGA) is utilized for appearance design. Lastly, the research process is explained using the proposed method, with the example of a coffee maker's design, and its effectiveness and practicality are verified. The proposed method aims to recycle waste, optimize resource utilization, achieve environmental protection goals, and provide innovative approaches for advancing the circular economy. Additionally, this method prioritizes environmental sustainability and considers emotional CRs.
