The safety of machinery is a very important aspect for its correct functioning in the conditions of modern production or assembly. According to the standards, manufacturers of special-purpose machines and devices are obliged to provide their equipment with a certificate of conformity (CE). This article describes the concerns of insufficient safety of a device. Insufficient coverage of part of the line meant that the certification did not take place, and the safety requirements were not met. The TRIZ method was used to resolve this technical discrepancy, providing designers with "instructions" on how to proceed, solve complex problems at the level of discrepancies and create solutions. By agreement of the designers, a solution that was not economically and implementation-intensive was created. All doors and windows within the fencing have been reinforced, thus achieving a greater degree of security. The resulting solution was subjected to simulations in the Ansys Workbench program, and the FEM analysis led to certain conclusions. The results were then moved to the structural engineer to assess the solution, who then approved the solution and successful certification of part of the device, respectively, in the assembly line.

The aim of the paper is to analyze student self-marketing and improve the methods of student self-marketing management. The concept of student self-marketing, which consists of various activities undertaken by students to make themselves known in the marketplace, is characterized. The application of the OTSM TRIZ Contradiction model and selected methods for contradiction analysis in the field of marketing management are proposed. The results of a survey on students’ self-marketing conducted among Poznan University of Technology students are presented. Several problems are identified and the contradictions in students’ self-marketing management are formulated. The selected techniques and tools for analyzing and solving contradiction problems were listed with reference to ARIZ-85. The prospects of their application in problem solving sessions with students, inexperienced in TRIZ, are examined. Workshop sessions are conducted with three groups of students. In the first session, an analysis of the Operational Zone (OZ), the Operational Time (OT) and intense contradiction is applied. In the second session, ideas are generated with an additional analysis of the Principles of Separation (Time, Place, Condition). In the third session ideas are generated with reference to the TRIZ Inventive Principles. The obtained results generated with various TRIZ techniques are compared and evaluated. The research findings indicate the potential of OTSM TRIZ Contradiction modelling to guide several recommendations for developing student self-marketing management.

The key ingredient, which provides the strongest impact on success of an innovation process, is the stage of generating new inventive solution ideas, which requires creativity and out-of-the-box thinking. Until the beginning of the 2000th, and even still very much today, creative engineering has been random and chaotic as it was not supported by scientifically based methods. As a result, the process has low effectiveness of dealing with situations demanding new inventive solutions. Introduction of TRIZ (Theory of Solving Inventive Problems) has radically changed the situation in many industries. TRIZ provides a structured support to organize engineering creativity based on many years of studies of innovative development of diverse technical systems and technologies. These studies helped to extract and formulate generic patterns of inventive solutions, which can be reused to produce new ideas in a much shorter time period rather than using traditional methods to enhance creative thinking. Although TRIZ has been successfully used in a number of industries, its use in maritime industry has been rather limited, most likely due to the low awareness by maritime engineers. This paper discusses modern TRIZ and presents some of its techniques that can be utilized in maritime engineering.

The article describes a method for analyzing and solving problem situations with the use of Su-Field models and 76 inventive standards. These tools are part of the “Theory of Inventive Problem Solving”. The author has presented the basic concepts of Su-Field models, including in the compilation of the most commonly used substances their fields and types of interactions in Su-Field models. The inventive standards have also been presented and grouped. Attempts have been made to solve two undesirable situations that occur during the operation of a complex technical system, which is the fuel injector of the self-ignition engine. Problem situations related to insufficient impact were modelled - too low tightening of the injector spring, and negative (harmful) interaction - erosive wear of the holes in the atomizer nozzle. Using the inventive standards of Class-1 and Class-2, general solutions to these problems have been found. After the transformation, exemplary detailed ways of solving the aforementioned problems have been presented in order to improve the design of the injector for these models. A summary and comments on the applicability of the presented methodology, regarding such complex technical systems, have also been presented.

Anticipatory Failure Determination (AFD) is a tool used in the TRIZ (Theory of Inventive Problem Solving) methodology. This article introduces its concept and describes the process of AFD in different versions of the method. The article presents the application of the AFD method at a very early state of a system’s development, i.e. its concept formulation stage, which corresponds to a technology readiness level (TRL) equal to 2. The system under analysis is a set of devices used to reduce displacement ship hull resistance. The system was modelled using functional analysis. An analysis of system resources was then carried out. Possible direct, indirect, and accident-related failures were identified. A multi-criteria analysis of the causes of system failures was conducted from which the top 10 potential failures were selected. Observations were made on the applicability of AFD in respect to systems not yet implemented.

TRIZ is systematic approach to innovation, being developed since 1950s. This acronym comes from the original Russian name of the methodology, which is usually translated as Theory of Inventive Problem Solving and sometimes abbreviated as TIPS. This methodology offers several concepts and tools supporting identification of problems and generation of solutions, which are directed towards required improvements. This directed approach differentiates TRIZ from other inventive methods, that usually rely on a trial-and-error formula. In the beginning, TRIZ addressed mainly mechanical systems. This paper presents short introduction to TRIZ, describing some basic concepts necessary to show inventive principles in appropriate perspective. These concepts are then used for presenting application examples coming from computer design domain.

The Miniature Dwarfs method is one of the tools used by the Theory of Inventive Problem Solving (TRIZ) used in the process of modelling and seeking solutions to conflicting situations. This article describes the origin of the Miniature Dwarfs method. The process flow of the usage of the Miniature Dwarfs method was presented both in its original version, suggested by Altshuller, as well as in its recently modified version. The usage of the Miniature Dwarfs method was presented here to minimize the marine hull resistance of a passenger ship in the conflicting situation, where there is a simultaneous necessity to provide both large ship capacity as well as high speed. The issue and the conflicting situation were both presented and modelled. The Operational zone and Operational time were described and modelled with the use of the Miniature Dwarfs method before and during the Conflict, and the desired situation. The search of the potential solutions was carried out with the use of miniature dwarfs; the findings were interpreted with respect to the system under analysis and the stated technical issues. Imagined situations described in individual diagrams are included in the issue under investigation. Selected solutions to the problem were presented. The advantages of the method were indicated and presented as an addition to other methods used in the process of designing new engineering solutions.

TRIZ trends predict an increased electrification of engineering systems. One of the visible effects of this is lighting, in this case party lights on boats. The need to furnish a boat with colorful illumination requires a flexible, redispatchable system. Cable-bound illumination does not meet this requirement. A solution is presented in this paper using TRIZ as a problem-solving methodology. TRIZ comprises a set of heuristic tools for problem analysis, reformulation, root cause analysis, and problem-solving algorithms. TRIZ, however, concentrates on generating solutions to problems irrespective of given limitations concerning, for example, safety, producibility, or cost. TRIZ provides a direction of thinking that has been proven successful in the past for similar problems. Other tools must, nevertheless, be used to carry out a technical evaluation of the feasibility of the solution, scalability, practicability, or cost target. TRIZ tools are widely used by engineers in multinational corporations such as Intel, GE, Philips, Siemens, Bosch, Boeing, Samsung, LG, and Cochlear. In this paper, selected tools from the overall TRIZ toolbox will be used and explained, with a focus on functional analysis, trimming, and resources. However, other aspects (Trends, Function Oriented Search (FOS), and Ideal Final Result (IFR)) will also be presented.

Over the past decades, demand for innovation in diverse industries, including the maritime industry, has been steadily growing. One of the primary sources of innovation has been the finding of inventive solutions to the most challenging problems. Until recently, the search for inventive ideas relied heavily on random and chaotic methods of boosting creative capabilities, thus drastically reducing productivity in the generation of new concepts and solutions. With the emergence of systematic methods for generating inventive solutions, the situation has changed. Modern methods such as TRIZ suggest a process of solving problems in a systematic way whereby each phase of the process is supported by the relevant analytical techniques and heuristic tools. This article presents Root Conflict Analysis (RCA+), a technique for problem analysis developed for the top-down decomposition of problems to chains of causes and contradictions. The article provides an example of applying RCA+ to discover the causes and contradictions which led a ferry to lose stability at sea.

Purpose: The objective of successful companies is the integration of customer requirements in the development process of a new product. Therefore, the Quality Function Deployment method has proven useful several times. The customer requirements often contain contradictions, which are mostly solved by compromises. The aim should be to integrate all customers’ demands and wishes into future products. Methodology: The theory of inventive problem solving can be applied to eliminate compromises in the product development. The method’s different tools enable a goal-oriented and systematic conflict resolution and may help to uncover trends. This paper displays an approach where individual tools of TRIZ are integrated into the Quality Function Deployment. Results: The result of this work is the presentation of the resulting benefits from combining the two methods. For this reason, individual tools of TRIZ are used in different points of the QFD process. The paper shows examples of starting points. Value of paper: In the context of this paper, the benefits from the interaction of QFD and TRIZ are presented. These are particularly evident in the initial phase of project implementation. In this phase the goal of the QFD process is to succeed in translating the voice of the customer for the company and then integrating it into the product development.

TRIZ methodology is a promising innovative tool to obtain various problem solutions, which are close to so called ideal final result - IFR. There are some introductory papers of present author like [Skoryna 10],[Cempel 12], [Cempel 14]. But it seems to be a need to make such an approachfrom different sides in order to see if some new knowledge and technology will emerge. In doing this we need at first to define the ideal final result (IFR). As a next we need to define a set of engineering parameters to describe the problems of vibration condition monitoring (VCM) in terms of TRIZ parameters, and also a set of inventive principles possible to apply on the way to IFR. This means we should present the machine VCM problem by means of engineering descriptive parameters and contradiction matrix of TRIZ. The paper undertakes this important applicational problem and brings some new insight into system and machine VCM problems. It follows from the paper that one can find 17 contradictions and use one set of inventive principles to solve specified contradiction of VCM problem, and also another set of principles to enhance obtained solution.

Metodologia TRIZ jest obiecującym narzędziem znajdywania rozwiązań problemów blisko tzw. rozwiązania idealnego. W diagnostyce maszyn jest już kilka prac na ten temat [Skoryna 10],[Cempel 12], [Cempel 14]. Ale nie jest to jeszcze podejście kompletne i wydaje się, ze jest cos nowego do znalezienia. W pierwszym rzędzie trzeba znaleźć idealny wynik końcowy, na jaki stan wiedzy i technologii nam zezwala. Następny krok to dobór parametrów opisujących problem, a potem w kategoriach tych parametrów znaleźć sprzeczności, jakie nas dzielą od wyniku idealnego. Likwidując te znalezione w pracy 17 sprzeczności korzystamy z zasad rozwiązujących Altschullera’a dopasowanych do diagnostyki maszyn. Robiąc to w pracy znaleziono dwie grupy zasad, takie, które przybliżają nas do rozwiązania i takie, które poszerzają to rozwiązanie.

The machine condition monitoring has not been approached by TRIZ2 practitioners, as yet, so the knowledge of TRIZ methodology has not been applied there. But it seems to be a need to make such an approach in order to see if some new knowledge and new technology will emerge from this study. In doing this we need at first to define the ideal final result (IFR). As a next we need to describe the problem of system condition monitoring (CM) in terms of TRIZ problem (engineering) parameters and to look for respective inventive principles. This means we should present the machine CM problem by the main tool of TRIZ, it means the contradiction matrix. When specifying the problem parameters and inventive principles, one should use analogy and metaphorical thinking, which by definition is not exact but fuzzy, and leads sometimes to unexpected results and outcomes, especially when doing it first time. The paper undertakes this important application problem and brings some fresh insight into system and machine CM problems. This may mean for example the minimal dimensionality of TRIZ engineering parameter set for the description of machine CM problems, and of course the ideal final result of TRIZ methodology.

This paper proposes a concept of knowledge engineering based innovative approach for seeking solutions related to electric al engineering systems. The knowledge base approach is discussed for its effectiveness at preliminary stages of solution hunting and solution design, which may reduce the iterations of design process and save time/cost. While referring research literature, this paper builds a hypothesis for novel and efficient usage of knowledge engineering tools for Electrical Engineers. The research seeks development of a methodological tool, which will be generic for aimed sub-sector (e.g. power distribution) of electrical systems. Based on structured innovation approach, this tool will provide conceptual guidance and direction to find solutions in sector specific electrical system problems. This structured approach and electrical engineering focus of the tool will facilitate electrical engineers for reaching practical and effective solutions with less expertise and time.
