Abstract. A technique for numerical evaluation of novelty is proposed for two types of technical system models, compiled on the basis of the patent formula of a new solution and a prototype. The first type is a block diagram in the form of a directed graph of the features of the invention. The second type is built as a flow of energy and information conversion from the input of the device to its output. The novelty coefficient is estimated by the degree of asymmetry of the schemes for the prototype and the new solution. The signs of the invention included in the restrictive part of the formula have symmetry. The distinctive part of the formula introduces asymmetry. In the block diagram of the graph, features are ranked by levels, and each level is assigned its own weight. In the information-energy model for the numerical evaluation of physical quantities, the theory of dimensions is used. The resource intensity of values is calculated in the system of kinematic values of Bartini. An example of a numerical assessment of the novelty of a membrane pressure sensor is considered in detail.

Keywords: novelty evaluation, formula of invention, prototype, symmetry breaking, physical quantity, dimension theory, Bartini basis, transfer matrix, resource capacity
