The topic for this final project with thesis was a product design project for Leonardo, an internationally successful glass and giftware brand, owned by the German design company Glaskoch B. Koch jr. GmbH + Co. KG. The goal of the project was to design a product family that would fit into the style and production methods used in the Leonardo collection and would have the potential to reach mass production. Research into Leonardo’s business profile as well as an analysis of product availability and features of the product collection were the basis of the design process. The goal of the product analysis was to determine the main product characteristics of the brand and interpret them through the eyes of a designer. Based on the results of the analysis, the style of the current Leonardo collection comprises of experimental forms, trendy surface structures, vibrant colour schemes and open approach to the characteristics of glass. The results of the analysis are based on a study of bowls, serving dishes, vases and candlesticks from the Leonardo collection. The design brief defining the appearance, function, production methods and user group for the design product family using Leonardo’s business profile resulted from the product analysis as well as the designer’s own interpretation. Through interpreting the company’s phrase ‘Inspiration for modern living in quality and emotion!’, the design brief situates the product family to be part of a youthful, modern consumer’s home. The report portrays the stages of the design process of the new product family followed in co-operation with the company. The process is portrayed starting from the designer’s initial product ideas continuing to the options chosen by the company and through further development to the final product samples produced by the company. The results of the work are hand-made prototypes made by the designer as well as product samples produced at Leonardo factory. These product samples may proceed to industrial production and may possibly be added to the Leonardo collection for the spring of 2008.
