Imaginary machine design: proposal of concepts, principles and a methodology as a new paradigm for preliminary design by optimization of engineering system
Résumé
This paper outlines the importance of the early steps of the design of engineering systems (the so
called preliminary or sketch phase design). If those steps should be probably addressed by an
optimization approach, we suggest an approach much more focused on the feasibility of the formulated
optimization problem (the so called “Problem Setting Phase”), than on the research of the optimal
solutions (the so called “Problem Solving Phase”), that we propose to address later in the design process.
That is why, this paper proposes an approach called “imaginary Machine Design” (IMD). The fundamental
principle of IMD is a reformulation of the design problem, initially formulated as a discrete optimization
problem in a real design space, toward a continuous and differentiable optimization problem in a design
space of “Imaginary Machines”. Besides the synthesis of the concepts, principle and methodology of the
approach, we show the efficiency of this approach for the preliminary design of electromagnetic devices
thanks to an overview of studies and results obtained for static converters, rotating machines and positive
energy buildings.
