THIRD HAND : A solution for the fuel tank assembly at Scania SödertÀlje
No full textScania recently introduced a new fuel tank design. This new design arose a need for extra help when mounting the tank in production, which was solved with two little hooks on each tank. These hooks are today known as the current third hand solution. Not only have these hooks added additional costs, but they have also significantly compromised the work environment at the fuel tank assembly. Since an assembler can assemble up to 40 tanks in a day, even a small change would make a big difference.  The aim of this thesis was therefore to improve the work environment for the fuel tank assemblers in the production at Scania SödertĂ€lje. The aim was also to discover an alternative solution that was both financially feasible and environmentally sustainable when compared to the existing hook solution. Therefore the objective was to create a new concept for holding the fuel tank in place during assembly, taking into account cost reduction and improved safety in production. The thesis was performed at LuleĂ„ University of Technology and Scania SödertĂ€lje during spring 2023 within the topic of Industrial design engineering.  The development of the concept has been done with the user in focus, a so called human-centred/user-centred work. To reach a concept that is designed for the user, the user has been involved throughout the entire project. Additionally a lot of focus has also been on topics that will help improve the concept from a human-centred view, for example ergonomics and usability. The project followed a linear process, with iterations when needed. The phases of the project were planning, context, ideation and implementation. During the project a bunch of creative methods have been utilized to reach the best result possible. The methods are in many cases chosen because they will contribute to a human-centred design. Example of used methods are interviews, user journey, speedstorming and prototypes.  The thesis resulted in a concept for mounting the fuel tanks in production. The concept is a redesign of the existing component, support plate. The concept is taped to the tank and used in a way similar to the current hook. The fact that the new concept is similar to the hooks means an easier transition for Scania, since production wonât be needing a redesign. The new concept is both cheaper and more environmentally friendly because it is an existing component. The concept also contributes to a better work environment for several reasons. The concept has reduced the risk of the tanks dropping and hurting the assemblers. The concept also provide an easy and pain-free assembly, which causes less stress and cognitive strain for the assemblers.Scania har nyligen introducerat en ny design pĂ„ sina brĂ€nsletankar. Den nya designen medförde att ett behov för extra hjĂ€lp vid upphĂ€ngningen av tanken i produktion uppstod, vilket man löste med tvĂ„ smĂ„ krokar pĂ„ varje tank. Dessa krokar kallas idag för en tredje handen lösning. AnvĂ€ndandet av krokarna har inte bara medfört en extra kostnad, men Ă€ven skapat en sĂ€mre arbetsmiljö i brĂ€nsletanksmonteringen. Eftersom en montör kan montera upp till 40 tankar per dag sĂ„ skulle Ă€ven en liten förbĂ€ttring göra stor skillnad.   Syftet med det hĂ€r examensarbetet var dĂ€rför att förbĂ€ttra arbetsmiljön för brĂ€nsletanksmontörerna i produktion pĂ„ Scania SödertĂ€lje. Syftet var ocksĂ„ att ta fram en lösning som Ă€r bĂ„de ekonomiskt fördelaktig och miljömĂ€ssigt hĂ„llbar jĂ€mfört med den befintliga kroklösningen. MĂ„let har dĂ€rmed varit att utveckla ett nytt koncept för att hĂ„lla tanken pĂ„ plats under monteringen, med hĂ€nsyn till minskad kostnad och ökad sĂ€kerhet i produktion. Examensarbetet utfördes vid LuleĂ„ Tekniska Universitet och Scania SödertĂ€lje under vĂ„ren 2023 inom utbildningen Teknisk design.   Utvecklingen av konceptet har gjorts med fokus pĂ„ anvĂ€ndaren, ett sĂ„ kallat mĂ€nniskocentrerat/anvĂ€ndarcentrerat arbete. För att uppnĂ„ ett koncept som Ă€r designat för anvĂ€ndaren sĂ„ har anvĂ€ndaren involverats genom hela projektet. Utöver att involvera anvĂ€ndaren sĂ„ har mycket fokus ocksĂ„ lagts pĂ„ Ă€mnen som hjĂ€lper till att förbĂ€ttra konceptet ur ett mĂ€nniskoperspektiv, till exempel ergonomi och anvĂ€ndbarhet. Projektet följde en linjĂ€r process med iterationer nĂ€r det behövdes. Faserna var planering, kontext undersökning, idĂ©generering och implementation. Under projektets gĂ„ng har en mĂ€ngd kreativa metoder tillĂ€mpats för att uppnĂ„ bĂ€sta möjliga resultat. Metoderna Ă€r i mĂ„nga fall valda för att bidra till en anvĂ€ndarcentrerad design. Exempel pĂ„ anvĂ€nda metoder Ă€r intervjuer, kundresa, speedstorming och prototyper.  Examensarbetet resulterade i ett koncept för upphĂ€ngning av brĂ€nsletankarna i produktion. Konceptet Ă€r en om design av den existerande komponenten support plate. Konceptet tejpas fast pĂ„ tanken och anvĂ€nds pĂ„ liknande sĂ€tt som kroken görs idag. Att det nya konceptet Ă€r liknande krokarna innebĂ€r en lĂ€ttare övergĂ„ng för Scania eftersom produktion inte behöver om designas. Det nya konceptet Ă€r bĂ„de billigare och mer miljövĂ€nligt eftersom det Ă€r en existerande komponent. Konceptet bidrar ocksĂ„ till en bĂ€ttre arbetsmiljö pĂ„ grund av flera orsaker. Konceptet har minskat risken att tankarna faller ner och skadar montörerna. Konceptet erbjuder Ă€ven en lĂ€tt och smĂ€rtfri montering vilket skapar mindre stress och kognitiv pĂ„frestning för montörerna
