Virtual Reality und Product Lifecycle Management – Entwicklung eines durchgängigen Prozesses für die BSH Bosch und Siemens Hausgeräte GmbH

Rehfeld, Ingolf, Wunderlich, Jan 25 September 2017 (has links) (PDF)
Weltweit führende Hersteller von Markenprodukten sind ihrem Anspruch verpflichtet, Benchmark der Branche für Qualität, Design, Innovation und Gebrauchswert ihrer Produkte zu sein. Dieses Ziel zu wettbewerbsfähigen Preisen und in immer kürzeren Innovationszyklen zu erreichen, ist kein zufälliges Ergebnis, sondern das Resultat visionärer Unternehmensstrategien, die schon früh auf standardisierte Produktentstehungsprozesse und durchgängige, unterstützende IT-Systeme im Rahmen eines konsequenten Product Lifecycle Management (PLM) setzen.

Metodologia e aplicativo de banco de dados para o desenvolvimento virtual de produtos / Methodology and database application for virtual product development

Carniel, Denize Regina January 2009 (has links)
Este trabalho tem por objetivo propor uma metodologia de desenvolvimento virtual de produtos por meio da criação de um aplicativo de banco de dados com componentes individuais e utilizando a tecnologia da realidade virtual (VRML) para a visualização do produto final. Para o desenvolvimento do trabalho foram investigados: a influência da difusão das tecnologias de informação e comunicação (TICs) no setor industrial; o processo de desenvolvimento de produtos e suas etapas; o design virtual e os recursos computacionais utilizados atualmente tanto na concepção quanto na prototipagem de produtos; a tecnologia da realidade virtual e sua aplicação nas diversas áreas, em especial, na indústria; e a utilização de padrões de metadados para a modelagem de banco de dados. O processo de intervenção ocorre por meio das seguintes etapas: análise e seleção de produtos para a montagem; projeto dos componentes individuais dos produtos; estruturação dos metadados; desenvolvimento do banco de dados e da metodologia de montagem. A metodologia de montagem é constituída de duas fases: na primeira, são definidos os pontos de inserção dos componentes (onde ocorre a conexão) e obtidas as suas coordenadas em um software CAD, a partir do seu modelo tridimensional, e também os demais metadados que caracterizam cada componente a ser cadastrado no banco de dados; criam-se arquivos em realidade virtual VRML de cada componente. Na segunda fase, modela-se o banco de dados, registrando todas as informações necessárias dos componentes e realizando a montagem dos produtos, através da conexão de dois componentes individuais em cada etapa de montagem. A metodologia de montagem de produtos virtuais está implementada no aplicativo de banco de dados chamado "dvPro", desenvolvido na plataforma do banco de dados Microsoft Access. O aplicativo possui interface amigável, possibilitando o cadastro de componentes, a montagem de produtos e a reutilização de componentes e produtos para a montagem de novos produtos, não exigindo do usuário grande conhecimento em banco de dados e realidade virtual. Apresentam-se dois exemplos de montagem de produtos, nos quais é possível verificar a viabilidade e a eficiência da metodologia proposta. / The objective of this work is to propose a methodology for virtual product development through the creation of a database with individual components and the use of virtual reality technology (VRML) to visualize the final product. For work development, the following subjects were investigated: the influence of information dissemination and communication technologies (ICTs) in the industrial sector; the process of product development, its stages; the virtual design and the computing resources currently used in design and product prototyping; the virtual reality technology and its application in various areas, especially in industry; and the use of metadata standards for database modeling. The intervention process occurs through the following phases: analysis and selection of products for assembly; design of individual product components; metadata structuring; development of database and assembly methodology. The assembly methodology has two steps: in the first, insertion points of components (where connections take place) are defined and its coordinates are obtained using a CAD software, based on the 3D model. Also, other metadata that characterize each component to be registered in the database are obtained and virtual reality VRML file for each component is created. In the second step, the database is modeled, recording all the information from the components and performing the product assembly, through the connection of two individual components in each assembly. The methodology for virtual assembly of products is implemented in a database application named "dvPro", developed on Microsoft Access database system. The application has a friendly interface, allowing component registration, product assembly and reusability of components and products to assembly new products. Only basic knowledge of database systems and virtual reality is needed to use the application. Two examples of assembly methodology are presented, where the feasibility and efficiency of the proposed methodology can be verified.

Three dimensional product presentation quality antecedents and their consequences for online retailers: The moderating role of virtual product experience

Algharabat, R., Alalwan, A., Rana, Nripendra P., Dwivedi, Y.K. 25 September 2020 (has links)
Yes / This study investigates the impact of three-dimensional (3D) product presentation quality (3D-Q) on attitude toward presented product and attitude toward website, which in turn affect users’ satisfaction. Therefore, this research developed a hypothetical online retailer website, which presents a variety of 3D laptops that allows users to control the content and form of the 3D flashes. We measured 3D-quality based on a multi-dimensional construct. In other words, we define and operationalize 3D-quality based on information quality, system quality, authenticity, and enjoyment (second-order). We employed a non-student sample (n=410) to collect the data. We find that 3D-quality determines perceptions of attitude toward presented product and attitude toward website, which in turn influence users’ satisfaction. Furthermore, we find that virtual product experience moderates the relationships between attitude toward presented product, attitude toward website and users’ satisfaction. Our study provides important implications for e-tailers.

Intuitive Interaktion mit Strukturdaten aus einem PLM-System

Schulze, Ernst-Eckart, Wolter, Lars, Hayka, Haygazun, Röhlig, Martin 25 September 2017 (has links) (PDF)
Einleitung Die Tätigkeit des Ingenieurs im Bereich der virtuellen Produktentwicklung betrifft neben dem Entwurf und der Absicherung einer dreidimensionalen Produktgeometrie auch die Erstellung, Analyse und Veränderung von strukturierten Produktinformationen. Dabei handelt es sich in erster Linie um Anforderungs-, Funktions- oder Produktstrukturen, welche innerhalb unterschiedlicher Phasen des Produktentstehungsprozesses in einem PLM-System verwaltet werden. Die Produktstruktur nimmt häufig einen zentralen Stellenwert ein, da sie als digitales Grundgerüst und Referenzstruktur innerhalb der Produktentwicklung gilt. Die Anzahl der strukturell organisierten Einzelteile und Dokumente für ein Produkt können je nach Sparte bis über 1.000.000 Elemente einnehmen (Carneo 2010), welche in mehreren Baugruppen über verschiedene Hierarchiestufen zusammengehalten werden. In der Produktstruktur werden zu dem unterschiedliche Varianten des Produktes über Konfigurationsregeln organisiert. Unter dem zusätzlichen Aspekt der zeitlichen Dynamik bei den Iterationszyklen des Entwicklungsprozesses kann für der Produktstruktur von einemkomplexen Informationsgebilde gesprochen werden.

Méthodologie collaborative d'aide à la construction de produits virtuels pour la conception d'aéronefs à propulsion électrique. / Collaborative methodology for virtual product building to support aerial vehicles with electrical propulsion design

Retho, Fabien 29 May 2015 (has links)
La recherche de moyens alternatifs pour la propulsion d'un aéronef est primordiale tant la dépendance au pétrole est forte. Le travail proposé dans cette thèse s'inscrit dans le besoin de soutenir les concepteurs de systèmes de propulsion innovants utilisant l'électricité. En partant du constat qu'il est primordial de s'appuyer sur l'analyse de l'aéronef dans sa globalité, nous proposons une approche basée sur les modèles, faisant appel aux modèles d’ingénierie système, aux modèles comportementaux basés sur la physique et à la simulation numérique, et collaborative, car la conception implique de nombreux métiers.L'objectif de cette approche est la création d'un produit virtuel qui est un modèle global multidisciplinaire exécutable du produit pour en faciliter la conception. Une méthodologie est alors construite pour se concentrer sur la relation entre le produit virtuel, ses modèles constitutifs et leur obtention. Le fil directeur de la méthodologie correspond à une recherche d'informations, au moyen de l'analyse des interactions et impacts multidisciplinaires qui apparaissent dans le système, puis l'application de cette information pour la construction d'un modèle d'intention qui permet la requête de modèles comportementaux auprès d'experts. C'est finalement le lien manquant entre la conception globale conduite par l'ingénierie système et la conception basée sur la physique du monde réel qui est implicitement traité dans ces travaux. Pour réaliser l'ensemble de la méthodologie, un nouveau rôle a été défini, le rôle d'architecte de simulation. Cette thèse présente la méthodologie de manière théorique, incluant ses rôles et concepts, puis cette dernière est démontrée sur un cas d'étude correspondant à l'hybridation d'un drone de type hélicoptère. / The research of alternative aircraft propulsion system is mandatory because oil dependence is too strong. The work proposed in this thesis is oriented to support electric based innovative propulsion system designers. Considering that it is important to consider entire aircraft analysis, we propose a model based, with systems engineering models, physics-based behavioral models and numerical simulation, and collaborative, because design require numerous business expertise. The objective of this approach is to build a virtual product, which means a global multidisciplinary executable model of the product under design in order to facilitate its design. A methodology is then developed, focused on the relation between the virtual product, its constitutive models and their acquisition. The methodology director wire corresponds to information research, with multidisciplinary interactions and impacts in the system, and then the application of those pieces of information to build a model of intention which allows requesting a behavioral model from experts. Finally, it is the missing link between global design driven with systems engineering and real physics based design which is implicitly at stake. To perform the methodology, a new role has been defined, the simulation architect. This thesis presents theoretically the methodology, including roles and concepts, and then this methodology is demonstrated on a helicopter based drone study-case.
