Popis:	SUMMARY Mechanical design equations which relate performance and functionality to design variables are often highly coupled, non-linear parametric equations. The structure of these interacting equations can be simplified by a reformulation based on the creation of alternative design variables. For many design configurations the reformulations results in highly beneficial improvements in equation monotonicity and complexity. The benefits include convenience and expediency in quantitative evaluations in addition to enhanced physical insight. They facilitate such important design activities as computing satisfactory solutions, active constraint recognition for optimizations, and the decomposition of design decisions. The reformulations can be thought of as alternative views of the design configuration that provide abstractions which can promote design synthesis. In this paper we discuss and illustrate the nature of these benefits with a number of simple design examples.
