Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Application of TRIZ Methods for the Analysis of Technical and Technological Requirements During the Formation of Technical Specifications for Aviation Products in a Life Cycle E.V. STEPASHKINA, V.V. SHISHKIN, A.A. ALEKSEEV, M.V. GRISHIN This article describes the driving factors to start the implementation of the initial stage of the product life cycle LLC "Research", based on the application of the customer's specifi ed parameters. The authors in the article present the moment of product design at the time of organizing the formation of the initial parameters necessary for further development of the technical task TOR for experimental design work OKR for the design object. The authors considered several more applied methods of the theory of inventive problem solving TRIZ, brief characteristics of the methods are given, and a comparative analysis for the justifi ed application of the chosen method to start the design. The paper presents the available types of analogies, and selected a more rational analogy in the opinion of the authors of the article, applicable at the initial design stage. The authors of the article present the prerequisites for the creation of a method for the development of technical specifications for a product using the principles of the theory of inventive problem solving, based on the analogies of existing products. The authors also show the connection between the stimulating external factors and the emergence of new future design objects by describing the prerequisites for creating a method for developing technical specifications for experimental design work for designing a new product or modernizing an old one. In the article, the authors will be asked to consider the moment of creating the parameters for the future product as a combination of the knowledge gained from the outside world, confirmed empirically. In the article, the authors have illustrated the scheme of organizing a single information space with the realized interaction between TRIZ and the ontology of the formation of TK using a hardware-software complex. Keywords: ontology, theory of inventive problem solving, analog, product, technical task, product life cycle. DOI: 10.25791/pribor.4.2021.1254 Pp. 33-41.
