NIJJ AB, a new established company, started its work with a patented idea for snow removal from the roof. This project developed the idea to a virtual prototype and presented the process of product development in a real case scenario. A combination of methods was implemented in this project to develop the concept in a structured way. The work started with planning for the project and gathering information about the customer needs, competitive products and related technologies. House of Quality was built to define product target specifications and obtain a working plan for the rest of project. Due to the complexity of the product, it was divided to simpler sub-functions and based on the collected information new concepts were generated for each sub-problem. After evaluating the combined concepts, most promising ones were chosen to be compared in Pugh matrix. The winning concept was selected for further development and more detail design. The designed components and assembly were tested with FEM tools and required refinements were applied to the design. A virtual prototype of the product was achieved at the end of the project.
