Technology-function matrix (TFM) is one of the most important methods of patent layout. The establishment of the TFM can help enterprise managers to make technology layout and market decision. In order to realize the information visualization and automatic construction of TFM, most of the researches focus on sematic annotation technology. The data for the construction of TFM are published patents. But research on the relationship between patents and TFM is insufficient. Considering the deficiency of current research, based on customer requirements and technology life cycle method, a TFM method is proposed. Firstly, customer requirements are accessed by Kano model, and then TFM is established by narrowing the technology domain through technology life cycle diagram. An engineering case is provided to verify the feasibility of the approach.
