This article describes an empirical study focusing on the systematic innovation process for finding disruptive technology opportunities. In the first part, the concept of the disruptive technology based on the bifurcation point of routes of system evolution of technology system is defined. The authors address three research questions. First, how does disruptive technology define? Second, what disruptive technologies of new product are most attractive in terms of interest from the customers from fuzzy front end of NPD? Third, in order to accurately find disruptive opportunities during the process of product detail design, how to establish models of function and find solutions from components of supersystem? The most notable achievement is a systematic flow constructed for achieving disruptive technologies systematically. Thus, the article provides a practical support for the methods to achieve disruptive technologies and the process is verified by case studies about copier and children’s phone.
