In the concept phase  the very basic elements of a new equipment or machine design are indentified.


In a concept the designer exposes the guide lines which will accompany the executive phase; these lines are general and the final product can move away more or less from the first concept proposal. In a project path can be more concept proposal that during the project development attest the points that the designer followed to reach the task; we can say that a project path is essentially formed by a concept project’s succession.

 

In HPE to find the concept, which is the principle solution, we start analyzing problems and finding the working principles. Then we combine working principles into working structures and we select suitable combinations with their variants. Finally, using technical and economic criteria, we find the concept. To fulfill this difficult task it’s necessary to establish function structures and in particular to divide the overall function into sub functions to find working principles.
