Sammanfattning: The scope of this thesis is the continual development of a wall fixture previously developed ina thesis as a concept together with specification on the final product. The specification from theprevious thesis describe that the wall fixture should meet all required standards for safety, butthe previous existing concept have not been fully developed according to this.The focus of this continuing work has been to see how demands on safety would affect thedesign of the wall fixture. The theoretical framework has therefore been on relevant safetystandards applicable on the Swedish market, and these have been a deciding factor duringdesign choices made during the continuing product development.The methodology has been an iterative work, wherein ideas for development have beendiscussed with Husmuttern, analysed for risks according to demands set by the safety standardsand finally put onto fabrication drawings enable fabrication of a prototype.The conclusion is that it´s possible to minimize risks in the concept phase, but that therequirements on safety makes that some of the demands in the specification have to be omitted.Previous demands on a purely mechanical operation with counterweight is deemed as to riskyfor the users, and a different solution with an electric engine system is chosen instead. This inturn puts demand to follow additional standards regulating the implementation of electronicsand control systems. The risk analysis that have been made should be updated to include thiswhen prototype is built. In conjunction to this the order of assembly of a wall should be chosento eliminate ergonomic risks, and the foundation for the systematic health and environmentwork should be done, two aspects of the health and environment that can’t be fully evaluatedduring concept development.
