Igloo
This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection. The proposals were gradedagainst the specification of requirements and compared with each other. The bestproposal became a construction with two round plates, one permanent and one mobile. Inthe plates there will be tracks in different lengths where a sprint will be able to slide andin this way fold out the sun protection in a certain number of stages.In order to see if the proposal worked as intended was a testing prototype done and theresult became successful.In stage two was a prototype in scale 1:4 built to study how the fabric and the lamellasbehave. On the prototype were a number of different experiments and tests done just toget the function working as good as possible.During the phase primary structure were blueprints to all unique parts developed andchoices of components were done. Calculations on critical situations have beenperformed and dimensioned after.The third and last stage was to build a prototype in full scale. Most of the unique partswere ordered from a row of different companies, while the others we produced ourselvesin the school's workshop. The readymade components was bought in and assembled.The assembly went well but certain improvements were needed to be done meanwhile.The project resulted in an operational prototype and a complete series with blueprints inorder to be able to produce the sun protection. In the conclusion were proposals toimprovements and advantages and disadvantages with the select structure discussed.
