Design engineering aims to provide transformation processes (TrfP) and technical systems (TS), preferably as complete transformation systems (TrfS), to solve a specific task. A theory-based systematic method for design engineering is outlined, which contains a cycle of problem solving. Some main elements of design engineering are discussed, with emphasis on two processes of analysis and synthesis. A relationship based on these processes of analysis and synthesis is developed between properties of existing TrfP and TS, and requirements for future TrfP and TS, and is supported by combining the properties and requirements with the steps in the cycle of problem solving. Vladimir Hubka's postulate of 1974 is thus confirmed that properties and requirements can usefully be separated into three main sections: external, internal and elemental.

Keywords: Design engineering, product properties, requirements, problem solving
