Ergonomi för tatueringsmaskiner (Swedish)
Abstract [sv]

Detta projekt gick ut på att undersöka ergonomiska problem med tatueringsmaskiner som finns på marknaden idag, att generera koncept om hur att förbättra problemen, och att sedan utveckla de koncepten i form av ritningar, CAD modeller och fysiska modeller. Processen börjades med att framföra en grundlig marknadsundersökning. Det som ingick i marknadsundersökningen var en infosökning, en kundundersökning i form av en enkät som skickades till tatuerare, och ett självtest av två olika tatueringsmaskiner. Resultaten som togs fram från marknadsundersökningen var att de största ergonomiska problemen var ljudnivå, vibrationsnivå, maskinvikt och balans, problem med grepp, och sladdkontroll. Områdena delades upp i tre olika problemgrupper vars fokus blev: tatueringsmaskin (apropå ljud, vibration och maskinvikt), greppet, och sladdkontroll. Genom en konceptgenereringsprocess togs fram tre nya produkter: en tatueringsmaskin som reducerar ljud- och vibrationsnivån och är enkelt att rengöra, ett silikon grepp som dämpar vibration och ger tatuerare ett bekvämt och återanvändningsbart alternativ, och ett silikon armband som reducerar viktpåverkan på handleden och eliminerar frustrationer om sladdkontroll. De tre koncepten blev utvalda på grund av att de presenterade de bästa lösningarna till ergonomiska problemen som kom fram via marknadsundersökning och dessa försäljningsmöjligheter. De slutliga koncepten presenterades sedan i form av en presentation och fysiska modeller på KEXPO utställningen.

Abstract [en]

This project was based on completion of an analysis of ergonomical problems with tattoo machines that exist on the market today, the generation of concepts to improve the situation, and the development of new concepts in the form of sketches, CAD models and physical models. The process began by completing a thorough market analysis. This was done via an information study, a customer survey in the form of a questionnaire that was sent to several tattoo artists, and a self-test in which two different tattoo machines were studied. The result of this analysis showed that the major ergonomic problems had to do with noise level, vibration level, machine weight and balance, poor grip ergonomics, and problems with cord control. These issues were then divided into problem focus areas, that is: tattoo machines (as to problems with noise, vibration and weight), grip, and cord control.Through an extensive concept-generation process, three different solutions were developed: a light-weight tattoo machine which decreases noise- and vibration-levels and made sanitization simple, a silicone grip which dampens vibrations and presents a comfortable and reusable alternative, and a silicone bracelet which reduces poor ergonomic effects on the wrist and eliminates frustration due to poor cord control. These three concepts were chosen due to the fact that they represented the best possible solutions to the ergonomic problems that were found during market research and because of their sales potential. They were then shown in the form of a presentation and physical model at the KEXPO exhibit.
