Technical Function Theory from the Perspective of Design Philosophy
The design philosophy formed after several turns of the philosophy of technology focuses on the technical artifact itself,which as a physical entity has the dual attributes of structure and function.As the result of design,the process of designing artifacts includes both the realization of physical structure and function,so it can be said that design is the connecting mechanism between the two nature of technical artifacts.The ICE theory under the use-plan approach proposed by Vermaas and Houkes,on the one hand,solves the problem of structure-function dualproperties of technological artefacts by giving the definition and interpretation of functional attribution from the perspective of the designer and the user,on the other hand,it overcomes the theoretical deficiencies of mere intention theory,causal-role theory,and evolutionary theory.Nonetheless,the explanation of the ontology status of technical artefacts by ICE function theory is still thin,and functional attribution cannot provide individualization criterion for technical artefacts.The dual nature of technical artefacts require a deeper and more comprehensive understanding of the relationship between design,use and function.
