Machine condition monitoring with inventive system TRIZ1

Cempel C.

Vibrations in Physical Systems

2012

Vol. 25

97--102

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.

Engineering parameters and contradictions in application of TRIZ methodology to vibration condition monitoring - VCM

Cempel C.

Diagnostyka

2012

nr 4(64)

55-62

TRIZ methodology is a promising tool to obtain solutions of problems close to so called ideal final result - IFR. There are some introductory papers of present author posted on Diagnostic Congress in Cracow [Cempel 12] and this year Wisła Machinery Diagnostic Conference. But it seems to be a need to make such an approach from 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 a set of engineering parameters to describe the problems of vibration condition monitoring (VCM) in terms of TRIZ parameters, and 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 contradiction matrix of TRIZ. 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. 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 use one set of inventive principles to solve specified contradiction of VCM problem, and also another set of inventive principles to enhance obtained solution.

Metodologia TRIZ to obiecujące narzędzie dla rozwiązywania problemów innowacyjnych, bowiem daje możliwość zbliżenia się do rozwiązania idealnego- IFR. Autor napisał kilka prac na ten temat, każda z nich oświetla inny fragment tej metodologii prowadząc do wzbogacenia wniosków. Tym razem pokazano że zasady wynalazcze TRIZ można stosować nie tylko do rozwikłania sprzeczności w parametrach, ale także w tym przypadku kiedy takich sprzeczności nie ma. Wtedy uzyskujemy możliwość polepszenia naszego rozwiązania na drodze do idealnego wyniku końcowego - IFR.
