Abstract:This report describes an internship performed at Orange Creatives. The internship was part of a product development project performed for the client Vitatools. The project assignment was to develop a human-powered juicing device. In the analysis phase information relevant to the internship was extracted from earlier results within the project, most importantly the design brief. This included information about the slowjuicer used in the device, the main principle of how the product functions and the requirements related to the technical design. In the concept phase a user test was performed to further specify the requirements. Subsequently, a number of technical solutions were investigated for various aspects of the design, of which the results were combined into a morphological chart, as well as a combination matrix, to display the compatibility of using solutions together. Part of these solutions were then used in the designs of three concepts. Of these concepts, the client selected the plug & play panels concept. After the selection by the client, the concept was further developed during the detailed concept phase. For each of the modules, technical solutions were chosen to fulfil their required functionality. In turn, these solutions were developed further to form the initial general design of the modules. After the concept was finalized in the detailed concept phase, the next step was to fully design the product, up to a production ready state. This was done in the engineering phase, where the geometry, dimensions, material and production processes were designed and selected for all components. Calculations were used to verify dimensions or the component selection of functional components and important load-bearing parts. From the completed CAD-model technical drawings were made, which were used to source production, receive production cost quotations and to receive feedback on the design. Subsequently, this information was used to further improve the design, resulting in a complete design. At the end of the engineering phase, the design was ready for the production of the first prototype to be ordered. The resulting design is a juicer wall, which allows its user to create a healthy juice through human power. It consists of a chair and, a movement input module, two wall segments supporting a system of gears and pulleys, and a table supporting a slowjuicer. The system starts with the movement input module, with which a user powers the system through a skelter rowing motion. The movement input is positioned on the foot of the right wall segment. Both wall segments combined form the wall. Along the wall, the gears and pulleys transfer the human input motion to the slowjuicer output. The slowjuicer is mounted on the table, which itself is supported by the left wall segment. During use of the product an assistant feeds ingredients into the slowjuicer. Unfortunately, it was not possible to manufacture the prototype during the internship, so the design could not be evaluated within this period, but has to be evaluated afterwards instead. The internship was finalized with a project transfer, to transfer data on the progression of the project thus far to a new employee and to evaluate the project.
