Plyschalternativ : – Nya lösningar för dammsugarmunstycken (Swedish)
Abstract [sv]

Detta examensarbete utfördes på Electrolux Floor Care and Small Appliences AB i Stockholm på deras primärutvecklingsavdelning. Syftet med projektet var att ta fram ett alternativ till dagens plysh-plattor, placerade på dammsugarmunstycket, som har som funktion att ta upp hår och fibrer från, i första hand, mattor.

Electrolux utvecklingsprocess, Product Creation Process, användes genom hela arbetet med några mindre anpassningar. Initialt gjordes en undersökning av hur Electrolux munstycken fungerar idag för att få en grundläggande förståelse för hur en lösning skulle kunna se ut och hur den skulle kunna påverka dammupptagningen. En brainstorming gjordes och ungefär 11 idé-förslag togs fram. Därefter påbörjades tester av både material- och formberoende lösningar. Flera av de mest lovande koncepten som sedan utvecklades kommer att utelämnas ur denna rapport då uppgifterna ansågs som känsliga på grund av eventuella patentansökningar.

Koncepten togs fram och utvärderades med hjälp av några av de metoder som presenteras i början av detta arbete. Detta ledde slutligen till två koncept av vilka ett antal prototyper tillverkades och testades.

Den slutliga lösningen visade sig fungera bra i tester. Det var från början meningen att det skulle vara två lösningar utvecklade från de två slutkoncepten. Dock kunde inte det företag som lovat producera den ena lösningen leverera i tid och detta gjorde att detta koncept inte kunde testas och utvärderas inom ramen för detta arbete. Konceptet i sig var dock så intressant att vidare tester skall utföras både på detta och på slutkonceptet.

Abstract [en]

This Final thesis was performed at Electrolux Floor Care and Small Appliances AB in Stockholm in their primary development department. The purpose with the project was to find an alternative for today’s plush plate, placed on the vacuum cleaner nozzle, whose function is to pick up hair and fiber mainly from carpets.

The Electrolux development process, the Product Creation Process, was used throughout the entire project with minor adjustments to fit the time plan and size of the project. Initially a study was made of the Electrolux vacuum cleaner nozzles to get a basic understanding of how a solution could look and how it could affect the dust pick-up capacity of the nozzle. A brainstorming session was executed and 11 suggestions for ideas were created. After this a number of tests where performed, both material- and shape-oriented ones. A number of the more promising concepts that was developed further will be excluded from this thesis due to patent issues.

Concepts was developed and evaluated with help of the methods that are being presented in the beginning of this thesis. This finally led to two concepts of which a number of prototypes were constructed and tested.

The final solution proved to function well in tests. From the beginning it was meant to be two solutions developed from the two final concepts. The company that was supposed to deliver one of them could not do so within the time limits and this led to the fact that this concept could not be tested and evaluated within the timeframe of this project. The concept proved to be so interesting though, that it was decided to go on with further testing both on this concept and the other one.
