Tiivistelmä
This thesis focuses on developing a sampling product. Product development aims to create new products or improve an existing version of a product or device. In this work, the goal was to enhance an old sampler model. The main issues with the original sampling mechanism are its heavy mass and complex structure.
The study was conducted as a constructive research project, consisting of a theoretical literature review addressing typical product development processes and Design for Manufacturing methods. Based on this theory, a product development framework was sought to facilitate the most efficient process for creating a new product. After the theoretical background, the requirements for the sampler were defined. These requirements were identified through known issues, interviews with the product management department, and by examining the existing models of the product. Based on this analysis, various product concepts were developed and compared to the original design and other concepts. The best concept was selected from these alternatives using comparison tables and simulations in SolidWorks.
During the work, six new concepts for the mechanism were introduced. Three of these concepts are for the frame structure of the mechanism, two are for the frame concepts of the cutter carriage, and one is for the equipment covers. These new concepts were significantly lighter than the original structure. The best concepts were selected through comparison tables following product development theory. The chosen concept was then examined through simulations in SolidWorks. The concept was modified slightly during the simulation process to ensure its structure was sufficiently durable. The modified concept performed exceptionally well in the simulation and was subsequently further developed.
The results of this study show that the selected and developed product concept is structurally durable to meet the sampler's requirements. The final design is 41% lighter than its predecessor and contains 39% fewer components. This represents a significant reduction in mass, and it can be anticipated that the number of hours required for manufacturing will decrease substantially due to the reduced component count.
