I denna rapport redovisas det examensarbete som har genomförts hos AQ Mekatronik där företagets egen körkontroll har genomgått en produktutvecklingsprocess. Examensarbetet har genomförts på Mälardalens Högskola i Eskilstuna där kursen omfattar 15 hp.Uppgiften som uppdragsgivaren bett författaren att genomföra handlar om att vidareutveckla den nuvarande designen av företagets körkontroll så att den visar på tydliga förbättringar jämte den redan befintliga produkten. Inga tydliga anvisningar om vad som ska förbättras eller hur det hela ska tas reda på har tilldelats. Det har varit till författarens uppgift att leta reda på svagheter hos den befintliga designen för att sedan lösa dessa på ett bättre sätt.De svagheter som författaren ansåg hos den befintliga designen handlade om handtagets ergonomiska ställning, behållarens möjlighet att bli mer utrymmeseffektiv, låsets onödigt komplicerade konstruktion och axelns svårmonterade skivor. Efter diverse produktutvecklingsverktyg så kom författaren fram till ett nytt handtag som erbjuder användaren en mer ergonomisk form och funktion, ett lås som består utav färre detaljer samt en behållare som är mer figurutformad för att på så sätt spara in på utrymmet. / This is a report of the exam the student Johan Engström performed at the University of Mälardalen in Eskilstuna in 2015, January to June to be more specific. The exam represents 15 university points and was performed over the period of 20 weeks. The orientation of the exam has been product development with further orientation in construction. Product development is something that the student finds very interesting and therefore does the orientation fit perfect for the student. The student contacted a company by name AQ Mekatronik and did after a meeting get an offer of doing his exam with them. AQ Mekatronik wants to renew their view on how their upcoming products can be developed to build new ways for opportunities. AQ Mekatronik wants the student to somehow improve the product that the company is selling today. The reason why the company wants the student to improve the product is because it can give the company some new ways to thing in the future. What the improvements more exactly will apply for or how they are going to be developed is there no directive for. It’s up to the student to find what to improve, why it should be improved and how it should be improved.The student started to plan the upcoming weeks of work so that the whole project will be so easy to follow as possible. The student has through the years at the University of Mälardalen used a product development methodology that has been taught through some of the courses the student has taken. The methodology goes after these following steps: planning, concept development, system-level design, detail design, testing and refining and lastly production ramp up. The student does not follow the methodology exactly but does instead modify it to fit the situations the student stands in front of. When the planning phase were over the student started to analyze the already existing product and the competitors’ products. By analyzing the existing product and the competitors’ products the student clearly can see what is good and bad with the existing product. After the analysis the student found some issues that the student wants to get some answers on after completing the exam. How can the product be more ergonomic, space effective and easier but still perform the same performances. Breaking down the issues results in the following issues: How can the handle be formed to offer the user a better ergonomic? How can the different details be moved to make the product more space effective? How can the shaft assembly be easier? How can the locks mechanism develop to be easier to provide easier assembly? To be able to improve the different constructions in the best way the student used a number of tools, function analysis, requirement specifications, QFD, brainstorming, Pugh’s matrix, FMEA, DFX. After the studies the student created some concepts and after some further work the concept ended to be something very much fitting for the end result. After completed the exam the student has now come to some final results. After completed exam the student has now developed a handle that is more ergonomic for the users hand and wrist and a lock that is more detail effective and also a container that is more figure shaped. The handle is using a more figure shaped handle, a rotation function that holds the hand in the same position all the time and a dead-man’s grip which allows the hand to come closer its resting positon. The lock has saved 30 % of its total detail usage and the mechanism is much easier in its design. A PCB card has been moved which means that the container can be more figure shaped which allows the container to save more room.This project has led to some clear improvements and the student can draw a whole lot of conclusions. The handle has been more ergonomic and the lock has been more detail effective. The student wanted the shaft assembly to be easier but the development would increase the costings for the company and it wouldn’t have been that much of a profit for the company.
