Development of Stroller (English)
Abstract [en]

After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent. From these concepts the one that was to be called Stealth was chosen. Stealth was further developed and CAD-files, pictures and blueprints were made for the frame Stealth has a classic and well tested suspension but now applicable with a three wheeled stroller. The frame is made up by aluminum profiles and injection moulded plastic details which link the profiles together. The frame is dimensioned to be smaller than Urban Jungle and its form is inspired by bicycles. Stealth has as of today a number of unique selling points and the frame is smaller than the maximum measurements specified. The number of unique parts has also been kept at a minimum. To continue the development the specifications for manufacturing have to be more defined, and the parts not treated in this thesis has to be developed.

Abstract [en]

Efter kontakt med företaget Elite Group Sverige AB, som säljer barnvagnar under varumärket Crescent Baby, fastslogs att projektgruppen skulle utveckla en trehjulig barnvagn som skulle bli Crescents första egentillverkade barnvagn. Endast barnvagnens ram behandlas inom avgränsningarna för detta arbete men hänsyn skulle tas till infästning för korg och hjul med mera. Crescent Baby önskade att ramen skulle vara mindre än konkurrenten Urban Jungel, att ramen skulle ha minst tre unika säljpunkter och att antalet unika delar skulle minimeras. Arbetet inleddes med informationssökning kring barnvagnar, konkurrenter, oberoende tester, europeisk standard och konsumentintervjuer. Därefter utvecklades ett antal konceptförslag som lämnades vidare till Crescent. Utifrån dessa koncept valdes det som fick namnet Stealth. Stealth utvecklades vidare och CAD-filer, bild och ritningsunderlag togs fram för ramen. Stealth har en klassisk och väl beprövad upphängning, men applicerad för att passa på en trehjuling. Ramen är uppbyggd av aluminiumprofiler och formsprutade plastdetaljer som länkar samman profilerna. Ramen är dimensionerad för att vara mindre än Urban Jungle och den har ett formspråk hämtat från cyklar. Stealth har i nuläget ett antal unika säljpunkter och ramens mått faller innanför de maximala mått som satts upp. Antalet unika delar har dessutom hållits nere för att förenkla tillverkning. För ett fortsatt arbete måste tillverkningsunderlaget definieras ytterligare och de delar som ej behandlats måste utvecklas.
