Abstract [sv]

Detta examensarbete inom integrerad produktutveckling utfördes vid Högskolan i Skövde i samarbete med Ericsindustrier i Töreboda. Rapporten beskriver metodiken samt processen som utförts i projektet för att uppnå samtliga målsättningar. Syftet bestämdes till en omkonstruktion av en justerskruv placerad i en expanderbar duschstång. Denna duschstång anses vara en viktig del av Ericsindustriers produktsortiment.

Grunden till behovet av en omkonstruktion ansågs vara antalet komponenter samt komponenternas montering. Detta krävde att komponentantalet minimerades genom DFx-principer där samma material eftersträvades genom produkten. Försämrad kvalité och hållfasthet definierades som kritiska områden då Ericsindustrier önskade att upprätthålla likvärdig kundnöjdhet samt att produkten skulle hålla för minst 200 N efter omkonstruktionen.

Projektets struktur följde en femstegsmodell där designprocessen inleddes med en förstudie. Fokus låg på informationsinsamling, observationer samt kartläggning av nuläget. Genereringsfasen genomsyrades av metodik för att utforska lösningsrymden. Detta innefattade bland annat brainstorming, morfologisk matris samt skissning. I projektet har prototyper haft en stor inverkan då de har fungerat både som generering samt utvärdering av lösningar. De har även agerat som kommunikation till företag samt användare genom hela processen. Iterationer har präglat hela processen för att uppnå en produktutveckling. För att upprätthålla en användarcentrerad design innefattade projektet flertalet användartester.

Fötterna till duschstången samt de två rören som bildar själva duschstången identifierades till separata problem. Dessa problem har diskuterats med företaget. Konceptval utfördes efter önskemål från företaget, tester, DFxprinciper samt diskussioner tills det mynnade ut i ett slutgiltigt koncept. Detta koncept uppfyllde de utsatta kraven samt behoven. Konceptet ansågs vara en prisvärd, högkvalitativ samt miljövänlig produkt.

Abstract [en]

This bachelor degree project in integrated product development was carried out at the University of Skövde in collaboration with Ericsindustrier in Töreboda. The report describes the methodology and the process that has been carried out in the project to achieve all the stated objectives. The scope was determined to be a redesign of an adjusting screw placed in an expandable shower rod. The shower rod is considered an important part of Ericsindustrier's product range.

The reason for the need of a reconstruction was the number of components and the components assembly. The component number was required to be minimized by using DFx principles where the same material was sought throughout the product. Decreased quality and lower durability were defined as critical areas since Ericsindustrier wanted to maintain customer satisfaction and the product must hold for at least 200 N after the redesign.

A five-stage model formed the basis of the project structure where the design process began with a preliminary study. The focus was on information gathering, observations and mapping of the current situation. The generation phase was imbued with methodology to explore solution space. This included, among other things, brainstorming, morphological matrix and sketching. In the project, prototypes had a great impact as they functioned as both generation and evaluation of solutions. They have also acted as communication with companies and users throughout the process. Iterations have characterized the whole process to achieve a product development. In order to maintain a user-centred design, the project included several user tests.

The feet of the shower rod and the two pipes that form the shower rod itself were identified as separate problems. These issues have been discussed with the company. Concept selection was carried out according to the wishes of the company, tests, DFx principles and discussions until it ended in a final concept. This concept met the required requirements and needs. Therefore, it was an affordable, high quality and environmentally friendly product.
