RTM mould design and construction for a DN 50 PN 16 flansch

The objective of this project consists of designing and constructing a RTM mould for a loose flange of glass fibre reinforced plastic (GRP). The design phase has the mission to realise a quality and simple design of the RTM mould, with the objective to obtain an easy and economic phase of construction and the more possible great characteristics of the loose flange. In fact this RTM mould will be a mould prototype, which will be developed in the future to obtain an RTM mould able to support a loose flange production. Therefore when more steps are developed in this project, then the future objective will be near

Costly search and design

Firms compete by choosing both a price and a design from a family of designs thatcan be represented as demand rotations. Consumers engage in costly sequential searchamong firms. Each time a consumer pays a search cost he observes a new offering. Anoffering consists of a price quote and a new good, where goods might vary in the extentto which they are good matches for the consumer. In equilibrium, only two design-styles arise: either the most niche where consumers are likely to either love or loathethe product, or the broadest where consumers are likely to have similar valuations. Inequilibrium, different firms may simultaneously offer both design-styles. We performcomparative statics on the equilibrium and show that a fall in search costs can lead tohigher industry prices and profits and lower consumer surplus. Our analysis is relatedto discussions of how the internet has led to the prevalence of niche goods and the"long tail" phenomenon.

Finding the Fit Between Engineering Design and Cost Information

This paper analyzes the possibilities of integrating cost information and engineering design. Special emphasis is put on finding the potential of using the activity-based costing (ABC) method. Today, the problem of cost estimation in engineering design is that there are two separate extremes of knowledge. On the one extreme, the engineers model the technical parametres behindcosts in great detail but do not get appropriate cost information to their elegant models. On the other extreme, the accounting professionals are stuck with traditional cost accounting methods driven by the procedures and cycles of financial accounting. Therefore, in many cases, the cost information needs of various decision making groups, for example design engineers, are not served satisfactorily. This paper studies if the activity-based costing (ABC) method could offer a compromise between the two extremes. Recognizing activities and activity chains as well as activity and cost drivers could be specially beneficial for design engineers. Also, recognizing the accurate and reliable product costs of existing products helps when doing variant design. However, ABC is not at its best if the cost system becomes too complicated. This is why a comprehensive ABC-cost information system with detailed cost information for the use of design engineers should be examined critically. ABC is at its best when considering such issues as which activities drive costs, the cost of product complexity, allocating indirect costs on the products, the relationships between processes and costs, and the cost of excess capacity.

Tuning the design procedures for laser processed microwave mechanics

This research has been focused at the development of a tuned systematic design methodology, which gives the best performance in a computer aided environment and utilises a cross-technological approach, specially tested with and for laser processed microwave mechanics. A tuned design process scheme is also presented. Because of the currently large production volumes of microwave and radio frequency mechanics even slight improvements of design methodologies or manufacturing technologies would give reasonable possibilities for cost reduction. The typical number of required iteration cycles could be reduced to one fifth of normal. The research area dealing with the methodologies is divided firstly into a function-oriented, a performance-oriented or a manufacturability-oriented product design. Alternatively various approaches can be developed for a customer-oriented, a quality-oriented, a cost-oriented or an organisation-oriented design. However, the real need for improvements is between these two extremes. This means that the effective methodology for the designers should not be too limited (like in the performance-oriented design) or too general (like in the organisation-oriented design), but it should, include the context of the design environment. This is the area where the current research is focused. To test the developed tuned design methodology for laser processing (TDMLP) and the tuned optimising algorithm for laser processing (TOLP), seven different industrial product applications for microwave mechanics have been designed, CAD-modelled and manufactured by using laser in small production series. To verify that the performance of these products meets the required level and to ensure the objectiveness ofthe results extensive laboratory tests were used for all designed prototypes. As an example a Ku-band horn antenna can be laser processed from steel in 2 minutes at the same time obtaining a comparable electrical performance of classical aluminium units or the residual resistance of a laser joint in steel could be limited to 72 milliohmia.

Ramp-up Predictability - Designing and Prototyping Ramp-up Predictability concept for new product creation

Diplomityön tavoitteena on tutkia ja kehittää menetelmä tuotekehitysprojektin ajalliselle ennustamiselle tuotteen siirtyessä tuotekehityksestä massatuotantoon. Ajallisen ennustamisen merkitys korostuu mitä lähemmäksi uuden tuotteen massatuotannon aloittaminen (ramp-up) tulee, koska strategiset päätökset koskien mm. uusia tuotantolinjoja, materiaalien- ja komponenttien tilaamisia sekä vahvistus asiakastoimitusten aloittamista täytyy tehdä jo paljon aikaisemmin.Työ aloitetaan tutkimalla rinnakkaista insinöörityötä (concurrent engineering) sekä suoritusten mittaamista (performance measurement), joiden sisältämistä ajattelumalleista, työkaluista ja tekniikoista hahmottuivat ajallisen ennustettavuuden onnistumisen edellytykset. Näitä olivat suunnitellun tuotteen ja tuotekehitysprosessin laatu sekä resurssien ja tiimien kompetenssit. Toisaalta ajalliseen ennustettavuuteen vaikuttavat myös projektien riippuvuudet ulkoisista toimittajista ja heidän aikatauluistaan.Teoreettisena viitekehyksenä käytetään Bradford L. Goldense:n luomaa mallia tuotekehityksen proaktiiviseksi mittaamiseksi sekä sovelletaan W. Edward Deming:in jatkuvan parantamisen silmukkaa. Työssä kehitetään Ramp-up Predictability konsepti, joka koostuu keskipitkän ja pitkän aikavälin ennustamisesta. Työhön ei kuulunut mallin käyttöönotto ja seuranta.Toimenpide ehdotuksena esitetään lisätutkimusta mittareiden keskinäisestä korrelaatioista ja niiden luotettavuudesta sekä mallien tarjoamista mahdollisuuksista muille tulosyksiköille.

Product Launch in Industrial Markets – Financial Risks in New AMD Elevator Door Launch

Tuotekehitys ja uusien tuotteiden lanseeraus on teollisen yrityksen menestyksekkään liiketoiminnan elinehtoja tämän päivän kilpailussa. Teollisuusyrityksen tuotteiden innovaatioaikakausia on ollut lukuisia, samoin kuin uuden tuotteen lanseerauksen lähtökohtia. Aikakausista, jolloin tuotteita kehitettiin yrityksen omista lähtökohdista, kuten valmistuksellisista eduista, on edetty tilanteeseen, jossa markkinoiden tarpeita tulee ottaa yhä enemmän huomioon. Kuitenkin, teollisuudessa esitellään tuotteita yhä puhtaasti tuotantolähtöisesti, ja tutkimuksen tavoitteena on selvittää taloudellisia riskejä, joita liittyy puhtaasti teknologiavetoiseen tuotteiden kehitystyöhön, valmistukseen ja lanseeraukseen. Normatiivisena tutkimuksena työ pyrkii asiakastarpeita ja teollisuusyrityksen loppuasiakkaiden näkökulmia huomioon ottaen osoittamaan markkinoinnin keinojen merkityksen tuotantolähtöisen tuotelanseerauksen taloudellisten riskien minimoimiseksi. Uuden teollisen tuotteen asiakastarpeita on selvitetty kyselymuotoisen markkinointitutkimuksen menetelmiä hyväksikäyttäen. Tuotteen tärkeimpien ominaisuuksien, kuten turvallisuuden, kestävyyden ja hinnan merkitystä voidaan hyödyntää ennen tuotteen kaupallista esittelyä potentiaalisten asiakassegmenttien kartoitukseen ja menestyksellisen lanseerauksen edesauttamiseksi.

This paper deals with the product design, engineering, and material selection intended for the manufacturing of an eco-friendly chair. The final product is expected to combine design attributes with technical and legal feasibility with the implementation of new bio-based materials. Considering the industrial design, a range of objectives and trends were determined after setting the market requirements, and the final concept was proposed and modeled. The product geometry, production technology, and legal specifications were the input data for product engineering. The material selection was based on the technical requirements. Polypropylene (PP) composite materials based on coupled-fiberglass, sized-fiberglass, and coupled-stone ground wood reinforcements were prepared and characterized. Final formulations based on these PP composites are proposed and justified

The contributions of netnography in new product development

Netnography has been studying in various aspects (e.g. definitions of netnography, application of netngoraphy, conducting procedure…) within different industrial contexts. Besides, there are many studies and researches about new product development in various perspectives, such as new product development models, management of new product development project, or interaction between customers and new product design, and so on. However, the connection and the interaction between netnography and new product development have not been studied recently. This opens opportunities for the writer to study and explore unrevealed issues regarding to applying netnography in new product development. In term of the relation between netnography and new product development, there are numerous of matters need to be explored; for instance, the process of applying netnography in order to benefit to new product development, the involvement degree of netnography in new product development process, or eliminating useless information from netnography so that only crucial data is utilized, and so on. In this thesis, writer focuses on exploring how netnography is applied in new product development process, and what benefits netnography can contribute to the succeed of the project. The aims of this study are to understand how netnography is conducted for new product development purpose, and to analyse the contributions of netnography in the new product development process. To do so, a case-study strategy will be conducted with triple case studies. The case studies are chosen bases on many different criteria in order to select the most relevant cases. Eventually, the writer selected three case studies, which are Sunless tanning product project (HYVE), Listerine (NetBase), and Nivea co-creation and netnography in black and white deodorant. The case study strategy applied in this thesis includes four steps e.g. case selection, data collection, case study analysis, and generating the research outcomes from the analysis.

Working fluid selection and design of small-scale waste heat recovery systems based on organic Rankine cycles

Demand for the use of energy systems, entailing high efficiency as well as availability to harness renewable energy sources, is a key issue in order to tackling the threat of global warming and saving natural resources. Organic Rankine cycle (ORC) technology has been identified as one of the most promising technologies in recovering low-grade heat sources and in harnessing renewable energy sources that cannot be efficiently utilized by means of more conventional power systems. The ORC is based on the working principle of Rankine process, but an organic working fluid is adopted in the cycle instead of steam. This thesis presents numerical and experimental results of the study on the design of small-scale ORCs. Two main applications were selected for the thesis: waste heat re- covery from small-scale diesel engines concentrating on the utilization of the exhaust gas heat and waste heat recovery in large industrial-scale engine power plants considering the utilization of both the high and low temperature heat sources. The main objective of this work was to identify suitable working fluid candidates and to study the process and turbine design methods that can be applied when power plants based on the use of non-conventional working fluids are considered. The computational work included the use of thermodynamic analysis methods and turbine design methods that were based on the use of highly accurate fluid properties. In addition, the design and loss mechanisms in supersonic ORC turbines were studied by means of computational fluid dynamics. The results indicated that the design of ORC is highly influenced by the selection of the working fluid and cycle operational conditions. The results for the turbine designs in- dicated that the working fluid selection should not be based only on the thermodynamic analysis, but requires also considerations on the turbine design. The turbines tend to be fast rotating, entailing small blade heights at the turbine rotor inlet and highly supersonic flow in the turbine flow passages, especially when power systems with low power outputs are designed. The results indicated that the ORC is a potential solution in utilizing waste heat streams both at high and low temperatures and both in micro and larger scale appli- cations.

Characterization of design of a product for additive manufacturing

The purpose of conducting this thesis is to gather around information about additive manufacturing and to design a product to be additively manufactured. The specific manufacturing method dealt with in this thesis, is powder bed fusion of metals. Therefore when mentioning additive manufacturing in this thesis, it is referred to powder bed fusion of metals. The literature review focuses on the principle of powder bed fusion, the general process chain in additive manufacturing, design rules for additive manufacturing. Examples of success stories in additive manufacturing and reasons for selecting parts to be manufactured with additive manufacturing are also explained in literature review. This knowledge is demanded to understand the experimental part of the thesis. The experimental part of the thesis is divided into two parts. Part A concentrates on finding proper geometry for building self-supporting pipes and proper parameters for support structures of them. Part B of the experimental part concentrates on a case study of designing a product for additive manufacturing. As a result of experimental part A, the design process of self-supporting pipes, results of visual analysis and results of 3D scanning are presented. As a result of experimental part B the design process of the product is presented and compared to the original model.

L’influence du développement durable à travers la formation universitaire en design industriel

Aujourd’hui, nous savons qu’environ 75 à 80% des impacts environnementaux des produits sont déterminés lors de la conception. Le rôle du designer industriel est donc crucial pour arriver à une forme de développement plus viable. Cette recherche tente de cibler les champs de connaissances qui devraient faire partie de la formation des professionnels du développement de produits pour y intégrer les aspects environnementaux. Après une recension de la littérature en design industriel, en pédagogie et en environnement, l’étude de terrain a été conduite en deux temps. Selon des critères prédéfinis, des programmes universitaires « spécialisés » en environnement/développement durable, au Québec, ainsi que des formations en éco-conception, offerts en France, ont été analysés. L’étude de terrain a été complétée par un entretien en profondeur semi-dirigé avec un consultant, qui aide des entreprises québécoises à intégrer l’environnement en développement de produits. L’analyse des informations recueillies met en évidence la nécessité de transformer rapidement les formations universitaires en conception de produits. Le nouveau cursus de design industriel devrait; 1. Intégrer les connaissances relatives aux impacts environnementaux; 2. Encourager le travail en équipes multidisciplinaires pour enrichir la collecte d’informations relative aux projets de développement; 3. Établir une collaboration étroite entre les établissements d’enseignement et les industries, ce qui est essentiel à la compréhension des enjeux de développement de produits et services (culture de l’entreprise, coût, délais, logistique, réglementation, etc.).

Understanding the past to imagine the future : the history of industrial design practice in Alberta

La pratique du design industriel dans la province canadienne de l’Alberta est en pleine croissance. Ses activités sont principalement concentrées à Edmonton et à Calgary, qui sont les plus grandes villes de la province. On y trouve des studios de design de renom, des communautés de design complexes et des programmes universitaires de design bien établis. Cependant, la pratique du design industriel albertaine est sous-développée en comparaison avec celle du reste du Canada et il y a peu de recherches et de documentation sur le design industriel en Alberta. Dans ce projet de mémoire, la pratique du design industriel en Alberta a été explorée depuis une approche historique. Pour pallier le manque de documentation, la collecte de données a été faite par une recherche qualitative, des entretiens narratifs et une recherche quantitative statistique. Une base d’information historique sur le design industriel albertain a été établie puis située par rapport au développement de la pratique du design industriel ailleurs au Canada. Les facteurs, événements et tendances dans l’histoire de la pratique du design industriel en Alberta ont été identifiés. De plus, le développement de la pratique du design industriel de l’Alberta a été comparé à celui du Québec et de l’Ontario. Les retombées de cette étude indiquent que la pratique du design industriel en Alberta présente quatre domaines de spécialisations distincts se développant depuis les années 1980. La pratique du design industriel en Alberta est sous-développée en comparaison à celui du Québec et de l’Ontario, mais elle peut devenir plus compétitive, au niveau canadien, avec plus de soutien gouvernemental, de meilleures relations avec l’industrie manufacturière et les institutions académiques, une communauté de design plus unifiée et en portant une plus grande attention aux domaines les plus prometteurs de l’industrie. Ces informations supportent une meilleure compréhension de la pratique du design industriel en Alberta et pourront informer les praticiens, enseignants et administrateurs du domaine du design industriel dans la province. Finalement, le mémoire servira de base à d’autres projets de recherche sur les changements potentiels dans la pratique du design industriel en Alberta et l’étude du design canadien et des industries de design régionales.

Work design and conflict in the workplace : the moderating effect of personality

La présente recherche a pour objectif d’étudier les effets que peuvent exercer la conception du travail sur le type de conflit qui émerge en milieu de travail. La notion de conception du travail se divise en trois dimensions, soit les caractéristiques reliées à la tâche, les caractéristiques reliées aux connaissances et les caractéristiques sociales. Ces dimensions sont mises en relation avec les deux types de conflit en milieu de travail, soit le conflit relié à la tâche et le conflit relié à la relation. Cette recherche vise également à vérifier l’effet modérateur des traits de personnalités sur les relations entre les dimensions de la conception du travail et celles du conflit en milieu de travail. Cette recherche est basée sur 473 participants qui occupent un emploi rémunéré et qui ont vécu une situation de conflit en milieu de travail allant jusqu’à 6 mois avant la période de sondage, allant du 14 au 18 janvier 2012. Les résultats indiquent qu’il n’y a pas de relations particulières entre la conception du travail et le type de conflit en milieu de travail. En ce qui a trait aux effets des traits de personnalité, les résultats indiquent que ces variables n’ont aucuns effets modérateurs sur la relation entre la conception du travail et le type de conflit en milieu de travail. Globalement, les résultats ne démontrent aucune relation entre la conception du travail et les types de conflit en milieu de travail, ou les effets modérateurs que les traits de personnalités peuvent avoir sur ces relations.
