Research on aroma-releasing flooring based on KANO-AHP-TRIZ model

The concept of the “olfactory economy” has recently emerged as a novel consumer trend. Flooring has been observed to emit an undesirable olfactory sensation during its initial use. The implementation of scented flooring has been demonstrated to mitigate this concern. This study examines the problem of undesirable odors emitted by engineered wood flooring during its initial application. A Kano-AHP model in conjunction with TRIZ theory was used to investigate market demand for fragranced flooring and to offer novel insights into its advancement. A questionnaire survey was administered to ascertain market demand for aromatic flooring. The Kano model was employed to assess user requirements, with a focus on individuals seeking aromatic flooring. This finding emerged after the investigation of fragrance intensity, comfort, and suitability. The aromatic flooring surface was then subjected to artificial olfactory testing, and the findings were statistically analyzed using the Hierarchical Analysis Method to rank user olfactory preferences by weight and priority. TRIZ theory was ultimately employed to transform these requirements into enhancement strategies for aromatic flooring. The findings demonstrate the efficacy of this research approach in translating user requirements into research and development trajectories, thereby enhancing the relationship between users and goods and offering novel insights for the research and development of indoor furniture panels.
