Abstract [en]

This report is the result of a product development project conducted at Sealeck Pty. Ltd, Adelaide, Australia. The project is the master thesis that Anton Bergstrom and Jimmy Lundin are required to write in order to obtain a Master of Science degree in Ergonomic design and production engineering at Lulea University of technology. Sealeck manufactures safety metal clad doors and windows and most jobs are customized. Currently the doors are assembled manually, but in the future Sealeck wants to assemble the doors completely or partially with the use of robotics. This type of production improvement requires a new type of door design, since the current solution involves aluminium cleats which are used to mechanically lock the two door halves together. The cleats are mounted with the help of a pneumatic chip hammer which take some time and make the assembly process hard to automate. Therefore Sealeck wanted the project team to come up with an improved door design that didn’t involve cleats and that could be manufactured with present technology. In order to develop the new door design a systematic approach was used. The systematic development process contains a number of steps which in the end leads to a final concept and hopefully a product ready for production. The first step was gathering information to get a basic understanding of the problem. This was done by participating in the production, benchmarking competitors, talking to employees and doing patent database searches. When this was done, sub solution concepts were generated and discussed with a focus group consisting of the project team, the R&D engineer and the managing director. Concepts were combined and further developed into several functioning prototypes. Each prototype was put through a fatigue test and compared to the current cleat based door. Improvements were made until a satisfactory concept had been developed. The final concept is a door which doesn’t use aluminium cleats, is easy to assemble, self aligning and manufacturable with the equipment used today. To make further product development easier for Sealeck, guidelines for manufacturing custom doors with our solutions are attached in the appendix.
