“…Patent application data can be used as a basis for judging whether a technical topic is at a mature stage or not. The judgment indicators include the technology growth rate (V) and the index of technology maturity (α), as shown in Equations ( 6) and (7). When both V and α have a decreasing trend, the technology topic is at the maturity stage [50].…”

“…The technical topic can, therefore, be judged to be at a mature stage. After counting the number of patent applications per year within the technical topic, the trend of V and α is obtained based on Equations ( 6) and (7), as shown in Table 9 and Figure 12. Observing the last ten years of data, the peak of V and α occurred in 2018, after which there is an occasional rebound, but the overall linear trend is decreasing.…”

“…For example, 3D printing technology has dramatically increased productivity in traditional manufacturing [5]. Although many firms have been pursuing RI, most innovations remain incremental due to the lack of research from an ex ante perspective to guide firms in radical innovative design [6,7].…”

The reasonable application of cross-domain knowledge tends to promote the generation of radical innovation. However, it is difficult to accurately capture the cross-domain knowledge needed for radical innovation. To solve this problem, this paper proposes a method for inspiring radical innovative design based on FOS and technological distance measurement. First, the functional analysis of the problem product is carried out to determine the target function. Second, the patent sets of problem domain and target domains are constructed based on FOS. Then, this study optimizes the method of technological distance measurement and uses it to determine the optimal target domain. After further categorizing and screening the patents contained in the optimal target domain, specific cross-domain knowledge is pushed to designers. This method can help firms select the most appropriate cross-domain knowledge to design solutions for different problems, thus increasing the possibility of generating radical innovation. In the end, the method is validated in the design of a stovetop cleaning device.
