Abstract:For this bachelor assignment for the study Industrial Design at University of Twente a search of solutions for a filling/dosing system has been conducted. The assignment is commissioned by Entocare, located in Wageningen. The goal of the assignment was to research to what extend it is achievable to develop a good working dosing mechanism, for the production line: Ladybug larvae, that meets the established requirements. Because the solution only has to dose one product line, first analysis has been conducted on the aspects surrounding the product and the packaging. The material, the packaging and the existing packing process has been examined. In the past, a filling/dosing prototype has been developed with the purpose to simplify the filling/dosing process. Therefore, this prototype has been analysed and an experiment has been conducted with this prototype to examine how it functions and to find causes why it does not function properly. An interview has been conducted to draft a statement of requirements with the commissioning company. With the results of the analysis, the interview and the experiment, requirements are defined for the filling/dosing system. With the requirements, research has been conducted to find suitable operating principles that can be implemented in the dosing device. Investigation of devices that dose comparable materials, resulted in suitable operating principles. Through idea generation, new operating principles have been generated. With the obtained operating principles, a component examination has been completed. Using the statement of requirements, the most suitable working principles are filtered. Next, the best operating principles are developed into concepts. The various parts are described and the device operations are explained in storyboards. Because the motion of the material, sawdust with larvae, is hard to predict, the expected difficulties are stated. In consultation with the supervisors and testing against the requirements, choices are made to construct prototypes for the testing of two concepts. First, SolidWorks models are made of these concepts. With these models choices are made for the construction and use of materials for the parts. The prototypes are constructed in a workshop of the University of Twente. The prototypes are tested with the product material by following a drafted test protocol. The researched aspects are observed, weighted and noted. With the results conclusions are drawn answering the test-goals. The ‘pushing’ concept functioned best in the tests. There still are complications with the concept which are described. The problems must be solved by further developments in subsequent steps. In the recommendations, possible solutions are described to develop the concept to a functional design. The ‘vibration’ concept will be recommended in case it appears that the ‘pushing’ concept will not function after further development.
