Research on Functional Analysis Useful for Utilizing TRIZ

AbstractThe functional analysis viewpoint is essential in ensuring that the customer has a voice in product design plans. Functional analysis is, therefore, very important in TRIZ, quality function deployment (QFD) and value engineering (VE), all of which are frequently used in design activities. People who are not used to conducting functional analysis may spend a great deal of time identifying a product's necessary functions, and this can have an adverse effect on the speed of product development and improvement activities. In light of this, this paper proposes a new methodology for effectively identifying—or “defining”—necessary functions (hereinafter referred to as “definition of functions”), based on Function and Behavior Representation Language (FBRL), which is a tool for ontology engineering. The paper also proposes a method for utilizing a functional diagram, which is used in functional analysis, in selecting various natural science effects in an Effects database, as well as in selecting features in a contradiction matrix. The latter part of this paper introduces a new method for definition of function and a method for using functional diagrams by examining their application in the field of agricultural machinery
