Concept Development of a Recliner Mechanism for a Car Seat

Mora Fontelles, Alejandro January 2016 (has links)
Nowadays, there are more and more regulations regarding the emissions of greenhouse gases. The automotive sector is directly affected by new standards enacted by the National Highway Traffic Safety Administration (NHTSA) in America and by European regulations in Europe that are forcing car manufacturers to produce more efficient cars. Different ways exist to increase the efficiency of a car and thus reduce the CO2 emissions. One known strategy to improve fuel economy in vehicles is by weight reduction. Consequently, car manufacturers are seeking out new companies that can supply them with lighter car components. Here is where VA Automotive enters the picture, as a car seat manufacturer that is willing to improve their product by reducing the weight of its various components. This study deals with the development of a new recliner design that demonstrates improvements in terms of weight, size and performance compared to the current solution used at VA Automotive. A common product development methodology has been developed to reach the final recliner design which went through the following steps. First of all, a benchmarking technique was adopted to gather as much data as possible from the competitors’ products. Then, a list of target values for the product specifications was defined as a guideline for the development of the product. The next step was to generate several concepts of recliner’s mechanism that were suitable to improve the design from VA Automotive. After that, a Pugh decision matrix was used to select the best alternative between the concepts generated previously. The optimal concept was further developed by generating four design alternatives that were analyzed in terms of manufacturing, assembly, weight and size by using the Lucas DFMA method. Finally some simulations were run for one of the designs in order to check the structural performance of the mechanism and prove this way that the new recliner design meets the requirements. When comparing the new design alternatives with the design from VA Automotive, it was noticed that all the new designs except one presented a lower manufacturing cost index. Moreover, for all of the alternatives of the new recliner design, the weight was reduced by more than 56% compared to the recliner used at VA Automotive. Finally, by means of FEM simulations it was demonstrated that by choosing the right material the new recliner design was able to meet the structural requirements.

Framtagning av en ergonomisk monteringsarm till kontrollpaneler med en modulär produktutvecklingsprocess

Oscar, Petersson, John, Heideman January 2017 (has links)
Norden Machinery AB i Kalmar är idag en ledande leverantör inom högpresterande tubfyllingssystem. Dessa är mestadels automatiska, men när det gäller förpackning finns det några arbetsmoment som utförs manuellt. Detta gör att de ergonomiska aspekterna kring dessa arbetsmoment måste prioriteras högt. I den nuvarande situationen utgör panelarmen som håller fast maskinens kontrollpanel ett ergonomiskt problem då den varken går att höja eller sänka. Syftet med projektet är att tillsammans med Norden utveckla en ergonomisk och användarvänlig lösning gällande panelarmen vid tubfyllningsmaskinerna. Frågeställningen behandlar hur detta görs genom att integrera design för ergonomi, flexibilitet och moduläritet i designprocessen. För att uppfylla syftet och frågeställningen med arbetet användes den grundläggande produktutvecklingsprocessen som Ulrich och Eppinger (2012) har tagit fram. Processen utgår från en förstudie där kraven på produkten sammanställs i en kravspecifikation och att designproblemet delas upp i mindre delproblem. Med detta som grund genereras koncept som därefter utvärderas mot kravspecifikationen vilket slutligen resulterar i att ett koncept väljs ut för vidareutveckling. Till dessa steg har teori och verktyg kring ergonomi, flexibilitet och moduläritet implementerats. Den slutgiltiga lösningen utgörs av modulära komponenter och är betydligt mer ergonomisk och användarvänlig än Nordens nuvarande konstruktion. Lyftanordningen består av en parallellogram och en gasfjäder omslutna av ett par balkar. Detta ger den lyftfunktion som krävs för att konstruktionen ska kunna hålla skärmen på plats och dessutom erbjuda höj- och sänkbarhet. Båda fästena gjordes i princip identiska och baserades på fästena hos Nordens nuvarande lösning. På så sätt behöver inga nya fästpunkter konstrueras och kostnaden kan hållas nere. Överlag förväntas konstruktionen uppnå de förväntningar och mål som både vi och Norden har. Den ergonomiska designaspekten passade bäst in vid förstudien, vilket beror mycket på att teorin kring ergonomi har sin grund i de regler, riktlinjer och mål som berör slutprodukten. Moduläriteten bidrog till att mer detaljerade koncept kunde skapas tack vare problem-uppdelningen. Flexibiliteten var inte fullt lika användbar men gav bra understöd till moduläriteten under processens gång. Huvudsaken är att vid en implementering likt denna ta hänsyn till eventuella kompromisser som kan behöva göras, och att alltid ha slutmålet med projektet i åtanke. / Norden Machinery AB in Kalmar is today a leading supplier of high performance tubing systems. These are mostly automated, but in the case of packaging, there are some operations that are performed manually. This means that the ergonomic aspects of these operations must be given high priority. In the present situation, the panel arm that holds the machine's control panel constitutes an ergonomic problem as it cannot be raised or lowered. The purpose of the project is to develop an ergonomic and user-friendly solution for the panel arm at the tube filling machines together with Norden. The thesis question addresses how this is done by integrating design for ergonomics, flexibility and modularity in the design process. In order to fulfil the thesis question and the purpose of the work, the generic product development process developed by Ulrich and Eppinger (2012) was used. The process is based on a preliminary study where the needs and requirements of the product are compiled in a requirement specification, and where the design problem is divided into sub-problems. With this in mind, it is possible to generate concepts. These are then evaluated against the specification which results in a concept being chosen for further development. During this process, theory regarding ergonomics, flexibility and modularity have been implemented. The final solution consists of modular components and is considerably more ergonomic and user-friendly than Norden’s current design. The lifting device consists of a parallelogram and a gas spring enclosed by a pair of beams. This provides the lifting function required for the design to keep the screen in place and offer raising and lowering possibilities. The screen- and machine attachment were based on Norden’s current design. This means that there is no need to construct new attachment points and the cost can be kept down. Overall, the design is expected to achieve the expectations and goals that both we and Norden have. Design for ergonomics were best suited for implementation at the preliminary study, since it is based on the rules, guidelines and goals that concern the final product. Modularity contributed to the creation of more detailed concepts due to the sub-problems. Flexibility was not quite as useful but gave good support to modularity during the process. The main thing is to consider any compromises that may need to be made in an implementation like this, and to always have the final goal of the project in mind.

Development of Spring Wire Feeder : Design for Spring Manufacturing with Coarse Spring Wire / Utveckling av fjädertrådsmatare : Konstruktion för fjädertillverkning med grov fjädertråd

Similä, Martin January 2021 (has links)
Lesjöfors Fjädrar AB is a spring manufacturing company. At the start of each manufacturing process when manufacturing cold coiled compression springs, the operators manually feed the spring wire from a reel that contains the raw spring wire, into the machine where the springs are made. This is a demanding process for the operators. The largest diameter of the spring wire today is 18 mm. Lesjöfors Fjädrar AB wants to increase the diameter to 22 mm and needs a new construction that allows feeding coarser spring wire from the reel into the machine. Trips were made to the factory in Lesjöfors where interviews and observations were made. A survey was conducted to gather information about the current process, as well as ideas for a new construction. With the information gathered, a requirement specification was made and approved by Lesjöfors Fjädrar AB. A brainstorming meeting was held at Rejlers Sverige AB in Karlstad with experienced constructors. The concepts generated during the meeting together with concepts generated alone were combined and evaluated using eliminations matrices and relative decision matrices. The highest ranked concept secures the spring wire with a hook inside the reel and extracts the spring wire with the help of a lift system. The lift system consists of a ball screw and an electric motor. After extraction, the spring wire is secured by two rollers before it is fed towards the machine by the electric motor currently installed on the reel. Along the way to the machine, the spring wire is steered/aligned by two pipes. The final concept was modeled in Autodesk Inventor Professional 2018 where the concept was designed in more detail. A stress analysis was conducted as a final step in the design phase. The final construction withstands the forces from the spring wire and makes it possible for Lesjöfors Fjädrar AB to start manufacturing cold coiled compression springs with a diameter of 22 mm, following the new working sequence made in this project. / Lesjöfors Fjädrar AB är ett företag som tillverkar fjädrar. I början av tillverkningsprocessen av kallformade tryckfjädrar matar maskinoperatören fjädertråden manuellt från en haspel in i maskinen där fjädrarna tillverkas. Detta är ett påfrestande arbete för maskinoperatörerna. Den grövsta tråden som används idag är 18 mm i diameter. Lesjöfors Fjädrar AB vill öka diametern till 22 mm och behöver en ny konstruktion som gör det möjligt att mata den grövre fjädertråden till maskinen. Besök gjordes på fabriken i Lesjöfors där intervjuer och observationer gjordes. En enkät skapades för att samla information om den nuvarande processen samt idéer gällande den nya konstruktionen. Med den insamlade informationen skapades en kravspecifikation som godkändes av Lesjöfors Fjädrar AB. Ett konceptgenereringsmöte hölls på Rejlers Sverige AB i Karlstad med erfarna konstruktörer. Koncepten som genererades under mötet samt koncept som genererades enskilt kombinerades och utvärderades med hjälp av elimineringsmatriser och relativa beslutsmatriser. Det högst rankade konceptet säkrar fjädertråden med en krok inuti haspeln och lyfter den med hjälp av ett hissystem. Hissystemet består av en kulskruv och en elmotor. När fjädertråden är ute ur haspeln säkras den med två rullar innan den matas till maskinen av den nuvarande installerade elmotorn på haspeln. På vägen mot maskinen styrs fjädertråden rätt med två rör. Det slutgiltliga konceptet modellerades i Autodesk Inventor Professional 2018 där det konstruerades i detalj. En spänningsanalys gjordes som ett sista steg i konstrueringsfasen. Det slutgiltliga konceptet klarar av kraften från fjädertråden och gör det möjligt för Lesjöfors Fjädrar AB att börja tillverka kallformade tryckfjädrar med 22 mm i diameter när de följer den nya arbetsmetoden skapat i detta projekt.

Understanding Knowledge Transfer in Complex System Product Development : Implications of Employee Exit

Tufvesson, Therese, Johnsson, Johanna January 2023 (has links)
Today employees are changing jobs more frequently than in the past, which can result in the loss of valuable knowledge and information during employee exits. This makes sharing of information and knowledge within the organisations more important than ever before, particularly during the product development process. The problem of losing knowledge during employee exits is a critical risk facing organisations.  It is worth noting that the study was inspired by the ethnographic research approach, with the purpose of understanding the nature of the phenomenon of information sharing in the product development process of small-scale complex system products and the aim to understand its implications during employee exits. The data for this study was collected through observation and interviews.  According to the results of this study, it was found that employees within the company used a range of techniques for storing and sharing information. The most common method used for finding and sharing information was informal meetings, however it was noted that there is room for improvement in this approach due to the potential impact of limited documentation. With regards to employee exits, the study revealed mixed opinions from employees regarding the existence of a formal off-boarding process. While some stated that such a process was lacking, others reported that it is indeed present. The process of transferring information and tasks to the next person seems to depend on the individuals involved, with some developing their own methods for handing over their work.  This study highlights the importance of context, reasoning, and decision-making when it comes to storing and sharing of information during the product development process, and the impact this has on the passage of knowledge during an employee exit. The knowledge transferred during an employee exit will determine the next person’s ability to work efficiently and effectively. There are numerous challenges in taking responsibility for a part or system without a comprehensive understanding of its history and background, especially when the previous employee in that role has left. Ultimately, this study emphasises the crucial importance of retaining experienced personnel and encouraging long-term employee commitment to the organisation.

An Investigation of Positive Engagement, Continuously Variable Transmissions

Dalling, Ryan R. 07 May 2008 (has links) (PDF)
A Positive Engagement, Continuously Variable Transmission (PECVT) allows for a continuously variable transmission ratio over a given range using positively engaged members, such as gear teeth, to transmit torque. This research is an investigation of PECVTs to establish a classification system and governing principles that must be satisfied for an embodiment to overcome the non-integer tooth problem. Results of an external patent search are given as examples of different concepts and PECVT embodiments that have been employed to negate the effects of the non-integer tooth problem. To classify all published and unpublished PECVT embodiments, a classification system is developed, based on how particular PECVT embodiments overcome the non-integer tooth problem. Two classes of PECVTs are defined: 1) the problem correction class and 2) the alternate device class. General principles that must be satisfied for a promising PECVT embodiment to exist in each class of PECVTs are also developed. These principles, along with the classification system, are the major contribution of this research. The principles describe what an embodiment in each of the PECVT classes must accomplish to negate the effects of the non-integer tooth problem. A product development phase integrated with TRIZ methodology is implemented to generate several concepts that satisfy the newly developed general principles and the product specifications that were also created. A screening and scoring process is used to eliminate less promising concepts and to find the most viable PECVT embodiment. An embodiment that only operates at preferred transmission ratios, where no meshing problems exist, proves to be the most promising concept based on the results of this methodology. The embodiment also utilizes cams and a differential device to provide the needed correction to the orientation of the driving members when misalignment occurs. This misalignment only occurs while transitioning between preferred operating ratios. A case study of the final embodiment developed by Vernier Moon Technologies and Brigham Young University is presented and analyzed to show how the final concepts ensure proper engagement without the effects of the non-integer tooth problem. The final embodiment is not the optimal solution but represents a conceptual design of an embodiment that satisfies the governing principles. The classification system and the governing principles that have been established are valid for all PECVT embodiments and will be valuable in future research. Future work yet to be conducted for this research, including an involutometry analysis, is discussed as well as other recommendations.

Design of breast roll retraction system : Redesign of keyway solution for positioning of breast roll in tissue machine / Konstruktion för uppbärning av bröstvals : Omkonstruktion av kilspårslösning för positionering av bröstvals i tissuemaskin

Sjöberg, Tobias January 2022 (has links)
This Thesis has been carried out as a final part of the Mechanical Engineering programme (180 credits) at Karlstad University during the spring semester 2022 and comprises 22.5 credits. The work is carried out on behalf of Valmet AB in Karlstad.At the beginning of a tissue machine, a mixture of fibres and water is fed into the machine and formed into a sheet using a forming wire and felt. During maintenance work, the wire sometimes needs to be detached from the machine. In order to release the forming wire, the breast roll retraction system needs to be opened up, which is done using an arm with the breast roll attached to it. This arm can rotate upwards, taking the breast roll with it, and when this is opened, the forming wire can be removed. In the hinge that this arm is attached to there is a gap, in addition to the gap the arm can be bent slightly. When the arm is returned to its original position after replacing of the forming wire, this gap and bending creates some problems. The problem is that the arm needs to return to its original position with great precision to avoid unnecessary adjustments. This is currently done using keys with angled walls and to lock the position eye bolts with associated nuts. The manufacturing of this solution has been identified as expensive due to tight tolerances and the angled walls of the keys and keyways. The aim of this project is to make the design cheaper to manufacture through design modification of this positioning and locking mechanism.Through a feasibility study regarding the current design and manufacturing method a deeper understanding of the function and machining was gained. The project has followed a structured product development process, from pre-study through requirements specification, concept generation and evaluation to detailed design. A requirement specification was developed using the results of the feasibility study together with information from Valmet employees. Two concept generation sessions were conducted, the 6-3-5 method and morphological matrix, these were done together with people at Valmet with different experiences. For concept evaluation and selection, Harris profile and relative decision matrix were used, these were conducted after consultation with experienced people at Valmet.The best concept is a design change that eliminates the milled angled walls in the keyway on the arm. These are replaced by a cylindrical pocket and a threaded hole. A corresponding change is made to the bracket against which the arm rests. Instead of the keys used today, two turned parts with a conical contact surface between them are proposed. This solution achieves all the requirements of the requirements specification as well as all the wishes except that it should fit similar fastening elements in other sections of the machine. The explanation for this is that the other fastening elements have slightly different functions which the proposed solution does not take into account. The price difference between the current design and the design proposed by the project has been obtained by a subcontractor providing price proposals for both. / Detta Examensarbete har genomförts som en avslutande del av maskiningenjörsutbildningen (180 hp) vid Karlstads universitet under vårterminen 2022 och omfattar 22.5 hp. Arbetet utförs på uppdrag av Valmet AB i Karlstad. I början av en tissuemaskin förs en blandning av fibrer och vatten in i maskinen och formas till ett ark med hjälp av en vira och filt. Vid underhållsarbete behöver viran ibland tas ut från maskinen. För att lossa viran behöver bröstvalsen öppnas upp, detta görs genom att bröstvalsen sitter fastspänd på en arm. Denna arm kan rotera upp och tar då med sig bröstvalsen, när denna är öppnad så kan viran tas ut. I gångjärnet som denna arm sitter på finns ett glapp, förutom glappet kan armen böjas något. När armen, efter att viran bytts ut, ska återgå till sitt ursprungliga läge skapar detta glapp och böjning viss problematik. Problemet är att armen behöver återgå till sitt ursprungliga läge med stor precision för att undvika onödiga justeringar. Detta görs idag med hjälp av kilar med vinklade väggar samt för att låsa fast positionen fäll skruvar med tillhörande mutter. Tillverkningen av denna lösning har identifierats som dyr på grund av snäva toleranser och de vinklade väggarna på kilen och kilspåret. Syftet med detta projekt är att genom designändring av denna positionering och låsningsmekanism få konstruktionen billigare att tillverka. Genom en förstudie gällande den nuvarande designen och tillverkningsmetoden skapades en djupare förståelse av funktion och bearbetning. Projektet har följt en strukturerad produktutvecklingsprocess, från förstudie genom kravspecifikation, koncept -generering och -utvärdering till detaljkonstruktion. En kravspecifikation togs fram med hjälp av resultatet från förstudien tillsammans med information från anställda på Valmet. Två konceptgenereringssessioner genomfördes, 6-3-5 metoden och morfologisk matris, dessa gjordes tillsammans med personer på Valmet med olika erfarenheter. För konceptutvärdering och val användes Harris profile samt relativ beslutsmatris, dessa genomfördes efter konsultation med erfarna på Valmet. Det bästa konceptet är en konstruktionsändring som eliminerar de frästa vinklade väggarna i kilspåret på armen. Dessa ersätts av en cylindrisk ficka samt ett gängat hål. Motsvarande ändring görs på konsolen som armen ligger mot. Istället för de kilar som används idag föreslås två svarvade parter med konisk kontaktyta mellan varandra. Denna lösning uppnår alla krav i kravspecifikationen samt alla önskemål förutom att den ska passa liknande förband i andra delar av maskinen. Förklaringen till det är att de andra förbanden har något annorlunda funktion som den föreslagna lösningen inte tar hänsyn till. Prisskillnaden mellan den nuvarande och den av projektet föreslagna designen har tagits fram genom att en underleverantör lämnat prisförslag på båda.

How In-House Usability Testing Increases Product Development

Seger, Jonatan January 2019 (has links)
Can the Product Development Process at Tcom be improved by moving usability testing in-house? The interest in this question lies in the agile transformation Tcom initiated in early 2018. Once agile, the company’s interests are efficiency and increasing quality. One way of increasing the quality of their digital products is to improve the process behind it, where involving users in usability testing should be central in an iterative development process. A qualitatively driven mixed methods research approach facilitated the acquisition of the empirical data necessary to successfully answer the research question. The culture of Tcom’s usability testing was collected via a survey. The survey was complemented with the current testing process through four interviews and two observations of usability tests, one internal and one external. Parameters between the two tests were compared and weighted against each other. The main findings reveal that the internal process shows promising characteristics. It is, up to, 1/10 as expensive per participant, has a quicker call-to-test-time, facilitates transparency, and allows refinement of the process. With the main findings in hand, the conclusion points to the fact that usability testing should be composed and conducted by Tcom itself. The greatest challenge to such a change is how a usability perspective can be integrated into the Scrum methodology. / Kan produktutvecklingsprocessen på Tcom förbättras genom att flytta användbarhetstester internt? Intresset i denna fråga ligger i den agila transformation som företaget påbörjade tidigt 2018. Effektivitet och kvalitet är centrala förbättringspunkter med det agila arbetssättet. Ett sätt att öka kvaliteten på deras digitala produkter är att förbättra processen bakom, där involveringen av användare i användbarhetstester bör vara centralt i ett iterativt arbetsförlopp. En kvalitativt driven mixed methods research metod tillämpades för att förvärva den empiriska data som krävdes för att framgångsrikt besvara frågeställningen. Tcoms användbarhetstestkultur undersöktes via en enkät. Denna metod kompletterades med 4 intervjuer och 2 observationer av användbarhetstest, ett externt och ett internt. Parametrar från de två observationerna ställdes mot varandra. De centrala upptäckterna avslöjar att den interna processen uppvisar lovande egenskaper. Den är upp till en tiondel så kostsam per deltagare, har snabbare beställning-till-test-tid, tillåter transparens, och möjliggör förbättring av själva testprocessen. Med hänsyn till huvudfynden kan vi konkludera att användbarhetstest bör utformas och utföras av Tcom själva. Den största utmaningen till en sådan förändring ligger i hur ett sådant användbarhetsperspektiv ska implementeras i det agila ramverket Scrum.

Produktutvecklingsprocess inom cirkulärekonomi / Product development process within circular economy

Alnajar, Abdallah, Jacobsson, Tobias January 2023 (has links)
Rapporten beskriver utförandet av ett examensarbete på högskoleingenjörsnivå. Arbetet utfördes på företaget WA3RM AB, vars affärsidé är att skapa värde från industriers outnyttjade resurser, genom att knyta samman olika aktörer och uppnå cirkulär ekonomi med syftet att minska klimatpåverkan och uppnå de globala målen för hållbar utveckling. WA3RM upplevde att arbetssätt i produktutvecklingsprojekt behövde kartläggas eftersom företaget i framtiden ville industrialisera fler produkter. Som ett led i WA3RM:s kartläggning av produktutvecklingsprojekt var examensarbetets syfte att skapa en process för konceptval i produktutvecklingsprojekt. Processen utformades efter WA3RM:s behov och examensarbetets mål var att besvara hur ett hållbarhetsperspektiv kan införas i fasen för konceptval i produktutvecklingsprojekt. Examensarbetet har skett med stöd av metoden Plan, Do, Check, Act, med syftet att strukturera och dela upp arbetet i delproblem. Problemområde och avgränsningar definierades och en kartläggning på företaget gjordes. Det gjordes en litteraturstudie utifrån kartläggningens resultat där verktyg och stöd för metoder identifierades till det slutliga förslaget, en process för konceptval. I kartläggningen identifierades tre huvudområden, krav & mål, hållbarhet samt cirkulärekonomi, vilka utgjorde grunden för litteraturstudien och förslaget, processen för konceptval.Processen för konceptval utgörs av fyra faser, där applikationer sorteras ut, rangordnas, kombineras till olika produkter, vilka slutligen rangordnas. I slutet av processen ska projektgruppen ha ett diskussionsunderlag som stöd för rekommendation till organisationen om konceptval för vidareutveckling i produktutvecklingsprojekt. En slutsats av examensarbetet var att metoderna och verktygen i processen ger möjlighet för att ta hänsyn till hållbarhetsperspektiv. Det anses dock viktigt att ta hänsyn till andra perspektivsom marknad och finansiering för att utveckla realiserbara och konkurrenskraftiga produkter, så att WA3RM kan fortsätta industrialisera produkter som minskar klimatpåverkan och inspirerar fler aktörer. / This report describes the execution of a bachelor's thesis. The work was conducted at the company WA3RM AB, whose business idea is to create value from unused resources in industries by connecting various stakeholders and achieving circular economy with the aim of reducing climate impact and achieving the global goals for sustainable development. WA3RM identified the need to map the work processes in product development projects, as the company intends to industrialize more products in the future. As part of WA3RM:s mapping of product development projects, the purpose of the thesis work was to create a process for concept selection in product development projects. The process was adapted to WA3RM:s needs, and the goal of the thesis work was to answer how a sustainability perspective can be established in the concept selection phase of product development projects. The thesis work was conducted using the Plan, Do, Check, Act method to structure and divide the work into sub-problems. Problem areas and limitations were defined and a mapping at the company was performed. A literature review was conducted based on the results of the mapping to identify tools and methods for the final proposal, the concept selection process. The mapping identified three main areas: requirements and goals, sustainability, and circular economy, which formed the basis for the literature review and the proposal, the concept selection process. The concept selection process consists of four phases, where applications are divided, ranked, generated to products, and finally ranked again. At the end of the process, the project team should have a basis for discussion to provide recommendations to the organization, regarding concept selection for further development in product development projects. A conclusion drawn from the thesis work was that the methods and tools in the process allows for consideration of sustainability aspects. However, it is important to consider other perspectives such as market and financing to develop feasible and competitive products, so that WA3RM can continue to industrialize products that reduce climate impact and inspire more stakeholders.

Breaking the Barrier: facilitating collaborative decision-making in product development : A product development study and design proposal

Ludwig, Persson January 2023 (has links)
In this work, a company's product development process with a specific focus on the decision-making steps in the earlier phases is investigated in order to improve the  overallproduct development and design process. Based on interviews with various  functions involved in the product development process,and a case study where a prototype of a real product was developed it was found that customer inputs and design requirements should be detailed and clearly integrated into the early decision-making steps in order to reduce confusion and facilitate the overall design process. During the case study, the general product design and development process by Ulrich and Eppinger was largely adhered to, although some modifications were made to identify potential improvements. The study suggests that there should be more investment of time in the product development process during the early stages, to clarify the underlying problem. This will facilitate communication and further development between the stages in which there will be a clear understanding between the developer(s) and management of what is important. It is also suggested to rank the different specifications quantitatively rather than qualitatively in orderto facilitate the decision-making process. The report includes the study of the company's product development process as well as the development of a specific product. The developed product is related to outdoor activities and can be described as a ladder that enables dogs as well as its owner to safely enter a rooftoptent. All critical steps in the development are described in detail

Utvecklingsprocessen för projekt med olika innovationsgrad / The Development Process for Projects with Different Degrees of Innovation

Algkvist Nordfors, Dante, Andersson, Jakob January 2021 (has links)
Företag över hela världen är beroende av innovation för att vara fortsatt konkurrensstarka på sin respektive marknad. Innovation existerar i olika grad där låg innovation, eller inkrementellinnovation, kan ses som en vidareutveckling av en produkt eller tjänst där mindre ändringar görs. Hög innovation, eller radikal innovation, kan istället ses som en utveckling av en helt ny produkt eller tjänst, som inte redan är existerande på marknaden. Alla företag använder projekt av olika storleksgrad med olika syfte. Projekten kan skilja sig sinsemellan med avseende på den grad av innovation som de har. I denna rapport undersöks och diskuteras det hur olika grader av innovation påverkar utvecklingsprocessen i projekt. Undersökningen har skett på ett företag inom halvledarindustrin som specialiserar sig inom högteknologiska produkter. Undersökningen har skett i form av fyra intervjuer av anställda med olika roller på företaget. Det är ett relativt litet företag som även är ensamma i Norden med tillverkning och distribuering av sina produkter. Inför arbetet har en litteraturundersökning genomförts, följt av intervjuer med fyra respondenter på det aktuella företaget. Resultatet visar på att det egentligen inte är några skillnader mellan projekt av olika innovationsgrad när det kommer till planeringsfasen av projekten. Under hela utvecklingsprocessen skiljer sig projekt av olika innovationsgrad åt med avseende på tid, resurshantering, externa parters påverkan, vikten av ett effektivt projekt samt hur viktigt ett projekt är för företaget. Resultaten från denna studie är inte absoluta i och med att det är ett litet företag med endast ungefär 50 anställda. Det är även ett företag inom en nischad bransch. För att resultatet ska vara applicerbart inom samtliga organisationer och företag krävs fortsatt forskning och en vidareutveckling på detta arbete där fler företag av olika storlekar inom olika sektorer analyseras och jämförs med varandra. De insikter och slutsatser samt den kunskap som detta arbete genererat kan då vara en källa till fortsatt forskning inom ämnet. / Companies all over the world are dependent on innovation in order to continuously keep their position on their specific market. Innovation exists within different grades whereas low innovation, or incremental innovation, can be seen as a further development of an already existing product or service. High innovation, or radical innovation, can instead be seen as a development of a completely new product or service, which is not already on the market. All companies use projects of different sizes and with different goals. The projects might differ between themself with respect to the grade of innovation. This report examines and discusses how different grades of innovation affect the development process within the project. The study has taken place on a company within the semiconductor industry where they specialize in highly technological products. It is a rather small company who is singularly responsible for the manufacturing and distribution of the products in the Nordic. Before the study, a preliminary investigation was made, followed by interviews with four respondents on the company in question. The results show that there is no actual difference between projects of different grades of innovation when it comes to the planning phase of the project. During the whole development phase the projects differ with respect to time, handling of resources, the impact of external parties, the importance of an effective project and the importance of the project to the company. The results from this study are not absolute due to the fact that it is a small company with only about 50 employees. It is also a company within a fairly niche industry. To have the result being applicable within all industries and companies, continuous research and further development of this study is needed where different companies of different sizes in different industries are analyzed and compared to each other. The experience and knowledge that this report brings might be a source for further research within the subject.
