This report presents two concepts for a product that is used for cable excavation. The first concept consists of a brush that is integrated with a collection container and the second concept consists of a brush that is integrated with a digging bucket. A test plan was also created to determine which dimension and material would yield the best results during excavation. The main purpose of this project was to increase the product range of Holm's industry in Motala by developing a concept that would minimize the risk of damaging cables during excavation. The product would also fit into the existing product range at Holms. The goal was to present two concepts for a brush that can directly be designed in a CAD program. To understand how the brush will operate, a study on existing products on the market was conducted. Then a study on the excavator attachments was made which resulted in OilQuick being a good solution because of its fast-hydraulic attachment. Customer needs were identified through interviews, which gave the impression that a brush that simultaneously collects soil would be a good solution. The result of the study was used to write the product specification. The product's many functions were divided into several parts to determine different solutions for each function. Thirteen concepts were prepared and a decision matrix was used as a tool to eliminate the concepts that would not be used. Several iterations of the concept development process were conducted where the results for each iteration were discussed to preserve the purpose of the project.
