Within ecodesign, various approaches exist in order to achieve product optimization [1]. Most of the approaches consist of an environmental assessment (full or abridged) of an existing product. The result from the assessment enables the product developer to select a strategy and to obtain design measures for possible product improvements. Now the problem is how to transfer these design measures to product changes. This leads in most cases to a simple technical problem which must be solved. For technical problem solving many methods exist on the market. Comprehensive lists of available methods for product development can be found in [2], [3] and [4]. From these lists useful methods have been selected, adapted to ecodesign and applied to a vacuum cleaner. The results of this example are presented and reviewed in this paper.
