in this sense, it could be related to far analogies, but perhaps more closely to conceptual combination
authors propose novel conceptual combinations (implicitly "inside a discipline"?? or outside??) as mechanisms for outsider innovation
the relevance for our question here is that inventors who explore a new field (to the extent that it is different from their own) and then later go on to invent new things that are better are at least possibly (we don't know for sure) doing a form of far analogies or conceptual combination: tough to distinguish.
also interesting is the idea of distant recombination, which feels like a mix of far conceptual combination and far analogies and outsider innovation, depending on the examples. don't find this to be particularly well theorized. but this connects very well to the way @uzziAtypicalCombinationsScientific2013 and @wangBiasNoveltyScience2017 think about things
