Theory of Technical Systems - Educational Tool for Engineering

ABSTRACT

Hubka's theory of technical systems (TTS) is briefly outlined. It describes commonalities in all engineering devices, whatever their physical principles of action. This theory is based on a general transformation system (TrfS), which can be used to show engineering in the contexts of society, economics and historic developments. The life cycle of technical systems consists of seven major TrfS, each consisting of further product-specific TrfS. From this TTS, Hubka derived a methodology as voluntary guide to systematic design engineering, for application when an intuitive approach based on experience proves to be ineffective. This approach to engineering design is distinct from more artistic designing. The methodology applies to novel design problems, and to re-design. Some educational aspects are developed to show the range of knowledge needed for engineering designing. Operators of a TrfS are also TrfS – illustrated by observing the management systems in the TS-life cycle. Connections to the general economy, and its financial consequences, are shown on TS-life cycle LC4 with its supply chain, and on LC6 and LC6A, with the need to service the operating product, and to establish supply and distribution chains. Transformation systems are hierarchical, each TrfS is a sub-system to a more complex system – each sub-system can be viewed as a TrfS, leading to a repeating use of the same design methodology for sub-systems. Invention and innovation in TrfS can be shown (historically) to alter the state of society, beneficially and adversely. A comparison with a different methodology is mentioned.
