This thesis describes the process and result of generating concepts for a new adjustable cutting tool with integrated components. It was conducted under a period of ten weeks at the department R&D Digital Machining at Sandvik Coromant, Sandviken. The focus of the thesis was to generate and evaluate different concepts using well known methods such as TRIZ Contradiction and 40 principles, SCAMPER, Wish and Wonder, Brainstorming, Weight Determination matrix and Pugh matrix.  To catch up on the latest technologies and similar tools in the industry today a literature study was conducted which resulted in a requirement specification for the concept in accordance with expertise from Sandvik Coromant. The key problems to be solved were the demanding tolerances and precision together with high forces and the limited space in the tool body.   The thesis resulted in a selected concept with chosen components to meet the demanding requirements. The concept is presented in a 3D CAD-model with description and necessary data. The conclusion includes recommendations to Sandvik Coromant to further develop the selected concept into a prototype so that physical test can be performed and lifespan of electronic components can be evaluated.

The capacitor test process at ABB Capacitors in Ludvika must be improved to meet future demands for high voltage products. To find a solution to how to improve the test process, an investigation was performed to establish which parts of the process are used and how they operate. Several parts which can improves the process were identified. One of them was selected to be improved in correlation with the subject, mechanical engineering. Four concepts were generated and decision matrixes were used to systematically select the best concept. By improving the process several benefits has been added to the process. More units are able to be tested and lead time is reduced. As the lead time is reduced the cost for each unit is reduced, workers will work less hours for the same amount of tested units, future work to further improve the process is also identified. The selected concept was concept 1, the sway stop concept. This concept is used to reduce the sway of the capacitors as they have entered the test facility, the box. By improving this part of the test process a time saving of 20 seconds per unit can be achieved, equivalent to 7% time reduction. This can be compared to an additional 1400 units each year.

Since businesses are constantly changing, making right decisions is a critical factor in order to achieve good results. In the thesis, two different decision support models are tested and the outcome is compared. This is done in cooperation with a company, Åmotfors Energi, who is facing a decision on how they can make use of their 30 GWh heat which they today do not have a paying customer for. Nine alternatives are used in the models and evaluated with seventeen different criteria. The purpose of this study is to compare and interpret the outcomes of two decision support models: the Analytical Hierarchy Process and Pugh Matrix Analysis. The purpose is also to investigate the main factors that influence the outcome of the models. The main research strategy was to use experimental design where three experts with various technical skills have scored the alternatives in both models. The alternatives have been carefully developed through an idea generation and idea selection phase. The results show that the models give different result when it comes to ranking the alternatives, both between the models and between the different experts. The empirical findings establish that the outcome from the models should be interpreted that the lowest scored alternatives can be eliminated for further research. The alternatives with the highest score should be further investigated before a decision could be made. Furthermore, what mainly affects the result is based on human factors. / Företag står inför ständiga förändringar och att fatta rätt beslut ses som en kritisk faktor för att uppnå goda resultat. I denna uppsats testas två beslutsstödjande modeller där utfallet av dem jämförs. Detta görs med hjälp av företaget Åmotfors Energi som står inför ett beslut om hur de kan använda deras 30 GWh värme som de i dagsläget inte har någon betalande kund för. Nio alternativ används i modellerna och utvärderas med sjutton uppsatta kriterier. Syftet med denna studie är att testa, jämföra och tolka resultatet från två beslutsstödjande modeller, den Analytiska Hierarkiska Processen och Pughs Matris Analys. Syftet är också att utreda vilka huvudfaktorer som påverkar utfallet av modellerna. Den huvudsakliga forskningsstrategin var ett experiment tre experter med olika tekniska färdigheter har poängsatt de olika alternativen i modellerna. Alternativen är omsorgsfullt framtagna genom en idégenereringsfas och en idéurvalsfas. Resultaten visar att modellerna ger olika resultat när det kommer till att rangordna alternativen, både vid jämförelsen mellan modellerna men även mellan experterna. Den empiriska studien visar att resultatet från modellerna bör tolkas som att de lägst rankade alternativen kan uteslutas, och de högst rankade alternativen bör utvärderas vidare innan ett besluta kan tas. Det som huvudsakligen påverkar resultatet baseras på mänskliga faktorer.

Flash is the unwanted or excessrubber material that presents on the outersurface of themolded rubber product. This will affect the surface finish; it is a cosmetic defect andit can be removed. It forms because of the leak or the excess molded rubber materialbetween the surface of the mold, typically on the parting line, (Jordan Anderson,2014). The presence of flash will reduce customer satisfaction. There are manymethods to remove the flash. The method is selected according to the degree of flashextension and the location where it occurs.The project aims to design a semi/full automated machine, which helps for having asmooth and fine surface finish of the weight plates. These plates are made up of rubberfor the ELEIKO group. The weight plates have different weights from 10 to 20 kg,but the diameter of each plate stays the same, but the thickness will be different foreach plate. The machine should be designed that removes all the excess rubber andshould smoothen the outer surface of the weight. The purpose of this work is to gainknowledge about different product development methods, respective tools, andtechniques that are used. The machine should be user- friendly, should not becomplicated, should not damage the workpiece (marks or trace of the blade), shouldnot put the employer in danger, and economically feasible.This report presents the progress of designing of the product, product development,methods, and literature study. The designed model can construct in the industry fortheir problem they are faced by the flash. The model is very simple and unique so thateveryone can perform the task without any previous experience. Material alternativeswere evaluated as well as manufacturing possibilities. The designed machine was theoffered for free as means for further research and development. Keywords: flashing, additive manufacturing, Ullman method, Pugh matrix, rubberweight plates, lever arm, smoothening tool.

På uppdrag av EQpack var projektets mål att utveckla ett koncept för en hyllvagn tänkt att användas i fabriksgolv av montörer. Hyllvagnen ska bära på kit-boxar med komponenter och ta upp mindre golvyta än befintliga hyllvagnar för kit-boxar. EQpacks idé var att till skillnad från konventionella hyllvagnar, i vilka kit-boxar placeras horisontellt till varandra och förs vidare med rullband, i stället ha hyllvagnar där kit-boxar kan placeras vertikalt i relation till varandra. Någon form av mekanism ska möjliggöra styckvis nedförsel av kit-boxar åt montören, i vilken form detta sker var föremål för utveckling i projektet. Utvecklingen av hyllvagnen skedde i fyra faser; analys och avgränsning, faktainsamling, genomförande samt utvärdering. Som förstudie har bland annat befintliga vagnar i en fabrik observerats vid arbete samt har samtal förts med de olika användarna om deras synpunkter. Under samtal med handledare sattes förväntningar, krav och avgränsningar. Genomförandet bestod av att ta fram diverse idéer och testa deras funktionsduglighet m.h.a bland annat lego. De olika koncepten analyserades och jämfördes med puhg matris. Med valda legomodellen som grund gjordes en CAD-modell med standardiserade komponenter som förslag på hur det skulle kunna konstrueras. Modellen uppmättes ta upp ca en fjärdedel av golvytan som en konventionell vagn tar. / The aim of the project was to develop a concept for a shelf trolley for EQpack, intended to be used on factory floors by assemblers. The shelf trolley must be able to carry kit boxes with components and take up less floorspace than existing shelf trolleys for kit boxes. EQpack's idea was to, unlike conventional shelf trolleys, in which kit boxes are placed next to each other horizontally and transported by conveyor belts, instead have shelf trolleys where kit boxes can be placed vertically in relation to each other. Some form of mechanism must enable piecemeal lowering of kit boxes for the assembler. How this is done was subject for development in the project. The development of the shelf trolley took place in four phases; analysis and boundaries, fact-gathering, exicution and evaluation. As a preliminary study, existing trolleys in a factory have been observed at work and discussions have been held with the various users about their views. Through discussion with supervisors the expectations, requirements and boundaries were set. The execution consisted of development of various ideas and testing their functionality with Lego. The different concepts were analyzed and compared with a puhg matrix. With the chosen Lego model as a basis, a CAD model was made with standardized components as suggestions for how a final product could be constructed. The final model was measured to take up about a quarter of the floorspace that the conventional trolley occupies.

This study used the Magical Garden software and earlier research into computational thinking as a point of departure to explore what metaphors could be used and how a teachable agent could be utilised to introduce debugging and error detection to preschool children between four and six years old. A research through design methodology allowed the researcher to iteratively work divergently and convergently through sketching, creating a Pugh matrix, conducting six formative interviews, and finally creating two hybrid-concepts as paths to teaching debugging in the form of concepts. Many metaphors discovered in the design process and in preschool teachers' daily practices were judged possible for teaching debugging and error detection. The analysis of these resulted in four recommendations for choosing a suitable metaphor when teaching debugging: it should have clear rights and wrongs, it should allow for variation, it should have an easily understandable sequentiality to it, and it should be appropriate for the age-group. Furthermore, six recommendations were formulated for utilising a teachable agent: have explicitly stated learning goals, review them and explore new ones as you go, have a diverse design space exploration, make the learning objective task complex, not the game in general, reflect on if using a TA is the best solution, make use of the correct terminology, and keep the graphical elements simple. These recommendations, together with the hybrid-concepts created, provide researchers and teachers with knowledge of how to choose appropriate metaphors and utilise teachable agents when aiming to teach debugging and error detection to children between four and six years old.

Målet med detta projekt har varit att utveckla en monteringsvänlig och kostnadseffektiv ljuddiffuser, en komponent som inte ska påverka ljudnivån och luftflödet för mycket, tillskillnad från den befintliga lösning som idag används i 3nine AB:s oljedimavskiljare. Examensarbetet följer den produktutvecklingsprocess som redogörs i boken Produktutveckling – Konstruktion och design av Karl T. Ulrich och Steven D. Eppinger. Där arbetet har anpassats för tidsramen på 10 veckor och delats upp i fyra faser. Fas1 – Förstudie, Fas 2 – faktainsamling, Fas 3 – Genomförande och Fas 4 – Rapportering. Den lösning som används idag består av fem vikta bitar sträckmetall som har sytts ihop med ståltråd, ljuddiffusern tar lång tid att montera ihop och att montera ned i maskinen. De fem vikta bitarna sträckmetall har vassa kanter efter klippning som försvårar monteringen ytterligare. En ljuddiffuser har en kostnad på 100 kr/st att framställa. För denna lösning togs mätvärden i 3nine AB:s verkstad fram som agerar som referensmätvärden, monteringstid – 333 [s], ljudnivå – 68 [dB], luftflöde – 319 [m ³/h] och DFA – index (mätvärde för monteringsvänlighet) – 5,4 %. Där 100 % ses som optimal monteringsvänlighet och högre DFA-index leder till reducerade kostnader. Då luft strömmar genom maskinen så påverkar detta mätvärdena och möjlig design av ny prototyper, men strömningslära är kunskaper som vi saknar och detta analyser med avseende på detta avgränsades bort. Genom Idéutvecklingsprocesser som Brainstorming, 6-3-5 Brainwritning, Morfologiskmatris, Pughmatris, konceptskisser, Virtuella koncept (3D-CAD) och friformsframställning (3D-utskrivning av prototyp) så togs fem prototyper fram som sedan testades för monteringstid, ljudnivå, luftflöde och DFA-index. Dessa tester resulterade i att det var en prototyp som utmärkte sig med förbättrade resultat jämfört med referensmätvärdena av befintliga ljuddiffusern. Mätvärden för prototypen ”45° väggen”, monteringstid – 16 [s], ljudnivå – 65 [dB], luftflöde – 342 [m ³/h] och DFA – index (mätvärde för monteringsvänlighet) – 93 %. Risk – och FEM-analys genomfördes på prototypen för att identifiera svagheter i konstruktionen, lösningar på dessa rekommenderas i form av små förändringar som t.ex. rundningar vid hörn. Dessa mätvärden redogör att den framtagna lösningen är bättre än dagens lösning och rekommenderas att implementeras och vidareutvecklas av företaget / The aim of this project has been to improve the existing noise diffuser used currently today in the oil-separatingmachines developed by 3nine AB. By reducing noise levels, increasing the air flow, increasing the “ease of assembly” and making it more cost effective. The thesis follows the product development process described in the book “Product Development - Construction and Design” by Karl T. Ulrich and Steven D. Eppinger. The work was adapted for a 10-week timeframe and divided into four phases. Phase 1 - Pre-Study, Phase 2 – Information gathering, Phase 3 - Implementation and Phase 4 - Reporting. The solution used today consists of five folded pieces of stretch metal that have been sewn together with steel wire, the noise diffuser takes a long time to assemble and to fit into the machine. The five folded pieces of stretch metal have sharp edges after cutting, which further complicates the assembly. The production cost for each diffuser is 100 kronor. For the present solution, the measurement values taken at 3nine AB's workshop were set as reference values, assembly time - 333 [s], noise level - 68 [dB], airflow - 319 [m³ / h] and DFA-index (measurement value for ease of assembly) - 5.4%. DFA-index when 100% is seen as the optimal ease of assembly and a higher DFA-index leads to reduced costs. As air flows through the machine, this affects the measured values and possible design of new prototypes, but fluid mechanics is one knowledge we lacked and therefor analysis of this was not possible and delimited. Through Idea Development Processes such as Brainstorming, 6-3-5 Brainwriting, Morphological Matrix, Pugh matrix, Concept Sketches, Virtual Concepts (3D-CAD) and Rapid prototyping (3D-prototype printing), five prototypes were produced, then tested for assembly time, noise level, airflow and DFA -index. These tests resulted in a prototype that featured improved results compared to the reference values of the existing noise diffuser. Measurement values for prototype "45° wall" where assembly time - 16 [s], noise level - 65 [dB], airflow - 342 [m³ / h] and DFA index - 93%. Risk-analysis and FEA was carried out on the same prototype to identify weaknesses in the design. The solutions to these weaknesses are recommended in the form of small design changes such as rounded sharp corners. These measured values state that the solution developed is better than today's solution and is recommended to be implemented and further developed by the company.
