Abstract:The job description is as follows: ‘Designing of products by reusing obsolete train timesheets’. The comment is executed for the design studio VerdraaidGoed, which designs sustainable products of residual material. As well as the yellow plastic train timesheets of the Dutch Railways. Once a new timetable is started, the times and traces are no longer up to date so the sheets are useless. Materials research of polystyrene (the material of the sheets) shows that it is covered by the thermoplastics. The fact that the material, under the influence of heat (at ±70°C), will be week and deformable, is in conjunction with the ways the material can be edited. Literature study and tests with the material by different processing methods led to nine suitable processing techniques, whereby the recognition of the sheets is maintained. These include laser cutting, vacuum forming, bending by means of a filament and draping. During the generation of ideas, the possible production methods are already taken into account. Products with a relatively simple and global shape appeared to be the most feasible in terms of production. There are two products designed for different target groups. From NedTrain there was a demand for a ‘trash street’, a table waste bin with several compartments to separate small waste. From the Dutch Railways there was a demand for a product that fits the needs and desires of customers and employees of the NS. Furthermore, for VerdraaidGoed it is important that the products are economically viable and easy to produce. After several sketch studies, making small models and research to competitive products, a number of ideas were selected using selection criteria. The concepts are a direct result of these selected ideas. On the basis of the Program of Requirements and the interests of the stakeholders, a concept was selected that has been developed and improved for both groups. The trash street is a curved holder that contains three uniform trays. Stickers on the trays indicate for which trash the appropriate tray is intended. The travel product is based on a so-called Four in a row game. The parts of the game are delivered in two A4 sheets. The user must assemble the parts themselves and after that, the game can be played by standing or hanging. The game is easy to close down and to take with, because the feet can be put in the upper side of the board. The calculation of the price tag of the trash street shows that the production will be profitable from a minimum of 500 units. After consultation with the NS and NedTrain, there is decided that the production will start, if they take at least 250 units. For the production of the travel product, all components will be laser-cut. Thereby ensures, that all components stay connected to the plate at one or more points. Laser cutting seems quiet expensive at first sight, but before that can be established, more companies have to be approached. Before any production can start, there are still some improvements that need to be carried out. First, the prototypes of the two products are not fully in line yet with the final design. Two complete prototypes should be realized. Second, the sliding of the coins and the hanging mechanism of the travel product should be further optimized. In the third place one or more ideas could be further invented and developed. Besides the two products that are developed, there is also created a summary of the analysis’ results. Once VerdraaidGoed starts designing more products of this material, research does not have to be done again. This way, the generation of ideas can be started more quickly.
