In this paper the assumption of a conflict between existing requirements and the application of new technologies will be illustrated by using examples based on shape memory technology. For this purpose, two product concepts are analyzed. Starting with the planning phase and the definition of system requirements, the described design processes also include conceptual, embodiment and detail design phases. Special attention is paid to the specification of requirements and their effect on the respective product concept. The aim of this paper is to identify influences on the product concept caused by the conflict between existing requirements and the application of new technologies. Certain requirements, e.g. historically based requirements, prevent the application of those new technologies in many cases. Therefore, the application of new technologies in combination with established requirements is investigated and then re-evaluated after the adaption of critical requirements.
