Tiivistelmä
The purpose of this thesis is to support an ongoing product development project in the case company. The thesis is examines if the product requirements are fulfilled after certain updates have been made to the product. Especially the requirements that are set by the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) are in the center of the focus in this thesis. For those elements, which do not meet the product requirements, the thesis aims to create optimized design solutions that fulfill the product requirements by utilizing Design for Six Sigma principles.
The thesis consists of three main sections: theory, current state analysis and making improvements to remedy the discovered problems. In the theory section, the thesis introduces the ADR requirements for a hooklift and Design for Six Sigma principles and tools which are utilized in this thesis. Current state analysis strives to identify which parts of the product require improvements. The aim of the final section is to provide solutions for the identified problems.
The research method used in this thesis is action research. First, theories are clarified and research questions identified and determined. Next, data is collected, which is then analyzed in order to improve the design. According to the analysis, certain changes are made to various design elements and finally, the solutions are reviewed.
As a result of this thesis, we have clarification for the mechanical strength requirements required by ADR regulations in the context of hooklifts. Even though the ADR regulations were ambiguous to interpret or directly targeted to hooklifts, we could produce a viable interpretation of them. As an outcome of this thesis, the product is now ADR compliant, interchangeable with older model and its hook is now equipped with a safety latch. A completely new safety latch concept was created during the project which turned out to be a viable solution that can be used in the facelifted product according to the prototype testing.
Overall, the product requirements were fulfilled successfully and we can be pleased with the results. For the company, the thesis supported an ongoing project by finding solutions for the problems that occurred in the design. In the future, ADR interpretation clarifies and eases design work of products that are required to be ADR compliant.
