Tools for Inventive Problem Solving on the Basis of Su-Field Models.

V.Petrov "System of Generalized Models"

The paper describes a system of generalized models that could be used for analyzing existing systems, synthesizing and forecasting new systems and solving standard inventive problems. The system of models includes standards for inventive problem solving, system evolution trends and contradiction resolution principles. 

M.Rubin "Representing Su-Fields as Matrices"

The author proposes to present Su-fields and Su-field transformation in the form of matrices. This approach enables to extend the possibilities of Su-field analysis and application of mathematical methods for matrix computation.

Yu.Murashkovskiy "Application of Standards Depending on Superproblems. Possibilities for Supplementing a System of Standards by Analogy with Non-Engineering Systems".

The paper describes a two-parameter scale "resource – object of changes" intended for determining a level of changes in a system. The author shows that the majority of standards of System-76 are intended for changing average levels. Certain standard changes characteristic of non-engineering systems are identified. The author demonstrates that it is possible in principle to transfer such standard changes into engineering systems.



Tools for Inventive Problem Solving on the Basis of Function Model.

S.Litvin  Function-Oriented Search (FOS)


N.Feygenson "Function-Oriented Information Search (FOIS) - history, potentialities, restrictions, and suggestions on efficiency enhancement".

The author describes the history of creation and application of Function-Oriented Information Search (FOIS) and analyzes the publications on this issue. Besides, the author presents the analysis of FOIS efficiency for the development and substantiation of concepts in consulting projects and identifies restrictions on FOIS application when improving certain classes of engineering systems. Recommendations are given on refinement of parametric requirements when formulating tasks for FOIS and new format for describing proven engineering solutions from "leading" branches is proposed. 


A.Pinyaev "Elementary Functional Transformations when Solving Inventive Problems Using Functional Prompts Method"

The paper describes a new approach to generating solution options for an inventive problem by means of basic functional transformations of the functional model of the problem. These transformations include changes of the subject, object or action of a function in a certain way such as segmentation of the object or compensation for the action. The suggested approach leads to a simpler and easier process for obtaining functional solutions of a problem, increases the number of the promising inventive solutions and reduces time required for idea generation within TRIZ-based project.


A. Pinyaev "Method for Analyzing Elementary Functional Transformations when Solving Inventive Problems Using Functional Clues Method"

The article describes a new method for inventive problem analysis and solving, which includes the why-why analysis (i.e. cause-effect analysis) of an initial technical challenge, building a comprehensive Why-Why Contradiction Map, function analysis of high-level contradictions in the Map and resolving these contradictions by means of the system of Functional Clues. The proposed method uses and develops well-known TRIZ techniques such as why-why and functional analyses. It also uses a new problem-solving tool – a system of Functional Clues. The proposed method is used in problem solving process and innovation training at Procter and Gamble Company, USA.


V.Petrov "Functional Approach"

This paper briefly described the "Functional approach" proposed by the author. The author considers function analysis of existing systems and functional synthesis of new systems. Special attention is given to functional synthesis.

A.Kynin, V.Lenyashin. "System-Based Consideration of Engineering System Evolution"


Inventors always wanted to forecast the evolution of one or another Engineering Systems (ES). Trends of Engineering System Evolution (TESE) represent tools for such forecasting. These trends are the foundation of the Theory of Inventive Problems Solving (TRIZ).

G. Altshuller published the main ideas of TESE in 1975. The most important part of TESE is dependence between evolution of product performance and product lifetime. This dependence is called curve of life stages or S-curve.

The goal of this paper is systemize and classify the life stages curves for different Engineering Systems. Application of proposed classification enables to forecast the future evolution of systems.


A.Efimov "Analysis of Evolution According to S-Curve: Goals and Main Principles".  


The author formulates main problems related to the analysis (in real projects) of engineering system evolution according to S-curve. The author also gives suggestions on solving identified problems owing to refinement of goals and tasks of this analysis and major steps of analysis performance. 

O.Abramov "Trends of Engineering System Evolution in Information Processing and Transmission Systems"

Attempts to employ TESE analysis to modern engineering systems (ES) for information transmission and processing (e.g., to telecommunication ES or to software products) systems are often unsuccessful due to difficulties. There is an opinion that classical TRIZ is unsuitable for analyzing such ES. This paper is an attempt to show on examples that many known TESE (if not all known TESE) are valid for ES for information transmission and processing.  

M.Rubin "Creation of Theory for Designing Innovation-Technological Systems"

The author proposes approaches to creation of a theory for designing innovation-technological systems (ITS). This theory considers inventions and business as a single process. Notions of multi-aspect approach, functional-targeted system and system "tissue" are proposed for designing innovation-technological systems.
