Abstract:This report describes the work and results of the bachelor assignment Industrial Design at the University of Twente, as done by Mark Scholte. This bachelor assignment was carried out during 14 weeks at Velda B.V. which is located in Enschede, the Netherlands. Velda is a company which specializes in pond products. The goal of the assignment was to develop an underwater filter. The developed concept will be sold alongside of the current underwater filter, the Internal Venturi Filter 3000. The assignment could be divided into three phases. These phases are; the analysis phase, the design phase and the realization phase. The phases together form the entire design process which reaches from a technical idea to a production ready concept. The main goal of the assignment was to design a better selling product than the current underwater filter. The most important subgoals of the assignment are costs, ease of use and styling. These subgoals are: - The filter has to cost less than the current filter. - The filter has to be available in two sizes, which are 20 liters and 30 litres - The filter has to be operated intuitional - The filter has to be styled according to the Veldastyling The first step of the analysis phase is describing the goals of the new filter. Hereafter, the Internal Venturi Filter 3000 was analyzed. This analysis focused on the technical operation and details, manufacturability and costs. This was followed by analyzing the styling of Velda products. Thereafter, the requirements of the filter were determined. The design phase started with the development of a technical design, in which styling had no importance. The main reasons for this design were the cost demands. To keep the concept inexpensive, a basic model had to be developed in which all parts functioned without expensive design solutions. Then, the concept was transformed into two sizes, which share several parts. After testing the filter, the concept got its final styling. Lastly, the concept was tested with the use of the program of demands. During the realization phase, a three-dimensional digital model was developed. This model was later used for making a cost calculation. In the end, some highresolution renders of the model were made. Another look at the subgoals was taken to test if the design achieves these goals. The costs of the filter had to be lower than the costs of the current underwaterfilter. As you can read on pages 29-31 the filter will cost € 32. This is significantly less that the € 37, which was the maximum amount. This subgoal seems to be obtained. Another subgoal was to design the filter in such a way that two sizes were available. With the designing of a 20 and a 30 litres version of the design this subgoal seems to be obtained as well. The two sizes share most of the parts, which keeps the costs at a low level. More on this subject can be read on page 19. Another subgoal was the intuitional operation of the filter. The filter is designed to basic, with simple connections and a low amount of parts. The results of this subgoal were not analyzed in this report. However, ways to accidentally damage the filter when not using it the proper way were analyzed. The results of this analysis were used to improve the filter. To the achieve the last subgoal, a design-analysis was made. Following this analysis, attempts were made to design the filter in such a way it is unmistakably a Velda product. The Velda CEO, who also is the mentor at Velda, was satisfied with the results. After making the conclusions, recommendations to the design were made.
