Tiivistelmä
The objective of this thesis was to develop a proposal for how a new steel-housed valve controller variant can be integrated into the existing assembly system, while maintaining performance and ensuring ergonomically safe conditions. The work was carried out for a large Finnish technology company.
This thesis is based on interviews and workshops with key personnel, observations of the assembly process, production data, and ergonomic evaluation of the workstations. In addition, relevant literature on assembly systems, ergonomics, Lean principles, and material presentation was reviewed to support the analysis.
The outcome of this study is a set of improvement proposals supporting the introduction of the new variant. The main proposals focus on the housing subassembly process, where kitting-based material presentation and consecutive pressing logic were introduced. In addition, various ergonomic refinements were proposed, along with minor adjustments in the assembly cell.
The results indicate that the new variant can be introduced with relatively minor adjustments. This thesis provides the case company with a practical set of proposals to safely introduce the new valve controller variant into the existing assembly system. Future testing is recommended to verify the effects of the proposed solutions.
