Abstract [sv]

Detta är en rapport som beskriver utvecklingen av ett produktkoncept som är tänkt att ersätta Weda:s SD-enhet. SD-enheten är ett munstycke som kan tillverkas från 1𝑚 upp till 10𝑚 brett i bockad plåt och sitter installerad på en drivenhet. Denna ersättare av SD-enheten ska göras mer anpassningsbar efter olika bassängstorlekar och billigare i tillverkningskostnader.

Baserat på kundkrav, problemställning och till följd av en utvecklingsprocess togs det fram fem koncept där samtliga stöds av grundläggande fakta, teoretiska tillverknings och monterings aspekter samt flödessimuleringar.

Dessa fem koncept sattes emot varandra i en sållnings matris för att sedan gå vidare med ett koncept som vidareutvecklades med hjälp av projektverktyg som QFD och DFA. Slutligen utfördes en laboration med en prototyp med syfte att undersöka och stärka projektets beräkningar.

Avslutningsvis analyseras resultaten som ställts upp mot projektets mål och kundkrav för att värdera om projektet har lyckats eller ej.

Abstract [en]

This report describes the development of a product concept that’s supposed to replace Weda's SD-System. The SD-System suction nozzle is scalable from 1 𝑚 up to 10 𝑚 wide out of bent sheet metal and is installed to a driving unit. The new pool cleaner attachment concept is supposed to be more modular to fit different basins and be cheaper in manufacturing.

Based on customer requirements, the problems description and the development process, five concepts were developed. All the concepts are supported by basic facts, theoretical manufacturing and assembly aspects as well as flow simulations.

These five concepts were opposed to each other in a screening matrix and then proceeded with a concept that was further developed using project tools such as QFD and DFA. Finally, a laboratory exercise was performed with a prototype and the purpose of investigating and strengthening the project's calculations.

Finally, the results that are set against the project's objectives and customer requirements are analyzed to evaluate whether the project has succeeded or not.
