The object of research is the theory of the design of technological machines and devices. The main idea of this theory is the possibility of a priori quantitative evaluation of the design of machine and instrument constructions for manufacturability, unification and other indicators based on the identification of structural design features and the creation of quantitative criteria. An in-depth study of this work has shown that the weaknesses of the research are related to the rather high influence of the heuristic component on the process of scientific and engineering search. One of the most problematic places is that the complete formalization of this process can lead to a halt in the development of scientific and technical thought. There is a risk of reducing the construction process to the reproduction of an infinite number of similar structures that differ in certain characteristics, but lie within the same constructive series. To prevent the negative impact of the proposed theory on the rate of technical progress, it is necessary to strictly limit the field of its use, using it to optimize the design of entire products or their individual components and automate the process of searching for a better prototype for improvement in a combination of features. To prove the main idea of the theory, methods of analysis and induction are used in the course of the research, on the basis of which, using the lemma and existence theorems, basic axiomatic theories are formulated with the subsequent completion of theorems, although the content of the considered theory is not mathematical, but technical objects. The structure theory of design is unique, since being a model of logical computation, it makes it possible to reveal regularities in classes and series of a set of designs on the basis of which to propose ways of optimizing and improving the productivity of the design process by establishing a connection between the features of the designs and their coding according to the chain of successive transformations. Coding of structures in place in the chain of transformations opens up wide prospects for automation of the design process.
