Application of functional features to the description of technical means conception

The paper presents the method of describing the conception of a future technical mean basing on the method of functional features. In order to determine the attributes which should characterize the functional features for the description of the conception of a technical mean it has been analyzed the different stages of the design-constructional-manufacturing process. Basing on the review of literature it was supposed the structure of the design-constructional-manufacturing process which includes the following stages: the need determination, designing, constructing, manufacturing and exploitation. In the process of designing-constructing-manufacturing one can distinguish models associated with each of its stages, and namely: the model related to designing (a conception), the model related to constructing (a construction), the model related to planning, the model related to manufacturing. The most important from mentioned models, in the terms of description of the conception of a technical mean, is the model related to the designing sub-process. It was assumed that the model related to the designing sub-process should include such information as: the structure of the system of a future technical mean (system of conjugations and transformations relationships), the design solutions of components of a technical system associated with the transformations relations, the design solutions of connections between components of s technical system mapping the established conjugations relationships between elements.
