Utveckling av Pappersmassestol
The author contacted designers Claesson Koivisto Rune Arkitektkontor in August 2007regarding his Master thesis at KTH. The company had discussed the possibility of creating achair made from molded pulp. The author was taken on as a manager for the project. Theobjective was to produce design documentation for a paper pulp chair which was to belaunched at the in 2008 Milan Furniture Fair. The purpose of the thesis was to develop aproduct with scientific methods as well as to investigate how to make collaboration betweendesigners and engineers easier through communication.The project went through four basic stages: Information, Analysis, Synthesis and Evaluation.Information on paper pulp, molded pulp, chair design, sitting postures and the existingmarket of molded pulp furniture. A requirements specification was established from thatinformation. The development of the chair was based on different models that woulddetermine different design aspects.The Paper Pulp Chair has two?part structure that utilizes closed geometries, double shellsand an inner stool for stability. The two parts are individually nesting, and are joined withcorresponding flanges. The paper pulp is mixed with a non?petroleum based thermoplastic,PLA, which enhances the material properties.The chair will not be launched at the Milan Furniture Fair 2008. Although, design documentsfor the chair has been produced, and the project continues together with Claesson KoivistoRune, STFI?Packforsk and Södra Cell. A grant from the Swedish Governmental Agency forInnovation Systems along with support from named companies has ensured the project?sprogress.
