Artefactos técnicos: ？Cuál es el enfoque más adecuado?

the paper describes the strengths and weaknesses of the three dominant approaches in the ontological theories of technical artifacts, which are the approaches: (1) functional, (2) intentional and (3) dual. i will show it is not appropriate to focus solely on "functions" or "intentions" to formulate a general theory of artifacts. the dual approach should not miss out on material and structural elements, but must also be consistent with symbolic elements and context in which humans live.
