Introduction.
This paper aims to support the analysis of technical systems with the help of TRIZ Function Analysis for products. Function modelling in engineering design is used for different purposes, e.g. analysis, understanding and depiction of systems, creation of ideas, transfer of knowledge, and depiction of structures of system [Ulrich and Eppinger 1995], [Pahl et al. 2006].
Different methods for system modelling exist. Each of them pursues different goals. Some modelling methods are used to understand the exchange and transfer of material, signal, or energy, e.g. flow oriented function modelling [Lindemann 2009], [Ehrlenspiel and Meerkamm 2013]. Others are used to depict the interaction between the user and the product, e.g. user-oriented function modelling [Rumbaugh et al. 1992], [Lindemann 2009]. Equally system models are used to subdivide complex systems in manageable small systems [Ulrich and Eppinger 1995].
A comprehensive function modelling toolbox is provided by the TRIZ methodology from G. S. Altshuller [Herb et al. 2000], [Klein 2007], [Orloff 2006]. This function modelling approach targets different fields of function modelling. First it is a tool to depict structures of systems. Second the tool can be used for analysis, improvements or adaptions of systems. The tool is well-proven and is a standard tool of TRIZ training [Adunka 2012].
This paper provides insights in the application of TRIZ Function Analysis. It describes the application of the approach in students projects and shows the advantages and obstacles that the users of TRIZ Function Analysis face. In order to overcome one of the obstacles, i.e., obtaining an interpretable system model, an adaption of the TRIZ approach is introduced.
The following paper is subdivided into the following sections: introduction of the TRIZ methodology (Section 2) and a detailed description of the TRIZ function modelling tool (Section 3). Section 4 describes the application of TRIZ Function Analysis and the problem statement of the arrangement of the elements of TRIZ function models. In Section 5 the adaption of the TRIZ function model is introduced. Examples of the application of the new approach from student projects are depicted in Section 6. Finally in Section 7, an overall conclusion is drawn about the application of TRIZ function modelling and its adaption as well as a summary and an outlook are given.

Avoid this product. The quality is terrible, and it started falling apart almost immediately. I wish I had read more reviews before buying. Lesson learned.
