Abstract [en]

An attractive product is one that functions well, is easy to use and has 'it'. Both technical and interactive functions are important. In this paper, the functional surfaces of a product and of its elements are regarded as carriers of functions. Some general principles are outlined starting with these concepts. Initially standard vehicle wheels were studied to find out what makes machine elements attractive. One difference between an individual machine element and a machine element acting together with other elements in a product is the often hidden interfaces between elements. An interface is defined as an interaction relation between two functional surfaces belonging to different elements. Some machine elements are also covered by others in order to prevent harmful effects from or on the environment. Some classic machine elements are covered by styled elements, whose functions are mainly interactive. The conclusions drawn from this study are that future machines will probably have more attractive covering elements than today, the attractiveness of machines is often increased when the performances of some classic machine elements are improved, new technologies such as drive-by-wire and/or new propulsion systems Will probably improve the attractiveness and performances of vehicles, the attractiveness of a universal joint is mainly related to how well the technical functions are fulfilled during its life, gears will continue to contribute indirectly to the attractiveness of many types of machines by their technical behaviours and performances and they are seldom visible but can be made visible if alternative lubricants are used and/or if lower performances are accepted, rolling bearings are normally regarded as high performance elements, bushings for different types of sliding bearings are styled in order to attract engineers and others before being assembled in a product and finally education in Machine Elements should be supplemented by an education of styled covering elements.
