Outline and structure of this paper
In order to outline this contribution we use the inventive approach introduced by Terninko [2]. Figure 1 shows the outline of this research’s purpose according to Terninko’s [2] four basic steps for inventive problem solving.

Similar approaches can also be found in the works of Orloff [4] and Marconi [5]. Whereby, Orloff does not entitle these four steps as Terninko but describes the problem solving process as a process containing four basic steps, which are Diagnostic, Reduction, Transformation and Verification.
During the first step of the approach – specific problem or diagnostic – a functional analysis of the examined artefact has to be carried out and a function model has to be set up. Using this function model as input for the next process step, abstract problem statements are formulated in order to identify entry points to problem solution. As in the previous section described, this paper introduces a methodology for the problem specification and for the structuring of the solution space derived by the function models.
In the following chapter 3 we outline and clearly define the terms used in the context of this research. In chapter 4 we introduce the functional analysis of this approach using a pneumatic valve as a case study. According to this case study we demonstrate in chapter 5 the resulted problem statements and the benefits of this approach.
