Proposal for a contents design of a graphic engineering lecture

In this project the subject of Industrial Design from the bachelor’s degree in Industrial Technologies and Economic Analysis of the ETSEIB is reviewed considering the contents and the teaching and evaluating methods. To acquire a great level and teach the subject with great quality, this project has been developed in order to grant that some of the best methods are used to teach and evaluate the students. The contents have also been reviewed to certify that a similar structure of contents is being followed the same way as some of the more relevant engineering schools. As this subject is part of the bachelor’s degree in Industrial Technologies and Economic Analysis, some of the subjects of the bachelor’s degree in Industrial Technologies, which is another degree from the ETSEIB, are used to compare and conclude the methods that could be used to benefit the subject. This has been done since these subjects have been used as a background to develop the contents and the organization of the Industrial Design subject. Research on some of the most relevant engineering schools in the world and in similar subjects such as Graphical Expression or Computer Aided Design has been done. This has determined the differences between the relevant and prestigious schools and the subjects of Graphical Expression or CAD. Once these different methods have been identified, they are considered to be applied to the organization of the subject, as a proposal, in order to enhance its quality and its reputation. To define which universities are better and more adequate for this project, some crucial facts have been used to reduce the research to a more specific group of engineering schools. The idea behind this project is to be able to clarify and help achieving a greater quality in the subject by reviewing some of the most relevant industrial design schools worldwide to apply some of the ways that they use to achieve such quality and reputation

Experimental Investigation of Sheet Metal Forming Using a Recyclable Low Melting Point Alloy Tool

Due to intense competition in automotive industry, new car models have to be launched as quickly as possible. A re-evaluation of the design and development phases has reshaped product development in order to get product earlier than competitors. Prototype production is one of the longest stages of product development due to physical verification activities. Shortening of this process will provide more opportunity to get project schedule earlier. Rapid prototype technologies are usually used as a guide for visual and packaging analysis. However, there is a requirement to use these parts for functional testing as well. Developing alternative rapid tooling methods which shorten the physical prototype production phase, while adequately supporting visual, packaging and functional aspects of sheet metal forming, can lead to considerable savings in vehicle prototype development. In this study, sheet metal prototype part using recyclable low melting point alloy was experimentally investigated by analysing dimensional conformance of tools and parts. In addition to wear performance, thickness reduction was investigated for stamped parts. Abstract in German: Untersuchung der Metallblechumformung unter Verwendung eines recyclingfähigen Werkzeuges aus einer niedrigschmelzenden Legierung. Aufgrund des intensiven Wettbewerbs in der Automobilindustrie müssen neue Fahrzeugmodelle so schnell wie möglich auf den Markt gebracht werden können. Um ein Produkt früher als die Wettbewerber fertig zu haben, wurde die Produktentwicklung durch eine Re-Evaluierung des Designs und der Entwicklungsphasen verändert

Computer-aided Reverse Engineering for Rapid Replacement of Parts

Indigenous product development using conventional means involves a relatively long leadtime and cost, especially for replacing worn out and broken parts. This paper presentsmethodologies and technologies for computer-aided reverse engineering, illustrated by a reallifecase study of an aluminium alloy separator body of a hydraulic filter assembly for the specialarmy vehicle. It involved reconstruction of part geometry using 3-D scanning, materialidentification using spectrometry, casting process optimisation using simulation software, andfabrication of prototype and tooling using rapid prototyping systems. It was found that thefabrication of wax patterns directly from reverse-engineered CAD data in a suitable rapidprototyping system (such as thermojet), followed by conventional investment casting, gives areliable and economic route for rapid development of one-off intricate parts for the replacementpurpose

ASME Mini-Baja RC CAR (Steering and suspension systems)

The issue that this project is concerned with is how to design and build a drivetrain, steering and suspension systems for an RC car. The systems must be simple and functional. Furthermore, these systems will be designed to fit on a small chassis and not interfere with each other. They also need to be strong and durable enough to propel the car forward and maneuver through various obstacles and be built in a way that is easy to take apart and repair quickly. These design problems were approached using basic mechanical design concepts such as gear kinematics, spur and bevel gear design, static and spring analysis as well as linkage design. These concepts were used to analyze the design and ensure it would function properly. Once the designs were finalized the necessary parts and components were machined, printed, and purchased. The result was a functioning RC car with all the necessary systems in place. These systems also fit well with each other on the chassis and they are relatively simple to assemble and dissemble. Overall the vehicle drives with sufficient power (approximately 20 mph), control (turning radius of under 50”) and meets the requirements set out by the principle investigators Mike Cox and Jason Moore

A survey of virtual prototyping techniques for mechanical product development

Repeated, efficient, and extensive use of prototypes is a vital activity that can make the difference between successful and unsuccessful entry of new products into the competitive world market. In this respect, physical prototyping can prove to be very lengthy and expensive, especially if modifications resulting from design reviews involve tool redesign. The availability and affordability of advanced computer technology has paved the way for increasing utilization of prototypes that are digital and created in computer-based environments, i.e. they are virtual as opposed to being physical. The technology for using virtual prototypes was pioneered and adopted initially by large automotive and aerospace industries. Small-to-medium enterprises (SMEs) in the manufacturing industry also need to take virtual prototyping (VP) technology more seriously in order to exploit the benefits. VP is becoming very advanced and may eventually dominate the product development process. However, physical prototypes will still be required for the near future, albeit less frequently. This paper presents a general survey of the available VP techniques and highlights some of the most important developments and research issues while providing sources for further reference. The purpose of the paper is to provide potential SME users with a broad picture of the field of VP and to identify issues and information relevant to the deployment and implementation of VP technology

Design, Rapid Prototyping, and Testing of the Darrieus Wind Turbine

This report contains design, rapid prototyping and testing of the Darrieus wind turbine. The Darrieus wind turbine rotates in the same sense regardless of the direction of the air stream. In order to maximize its efficiency, several variations of this turbine design will be required for testing and evaluation. One of the objectives of this project is to test parameters that will affect the performance of the Darrieus wind turbine. Two parameters that will evaluated for evaluation is number of blades of the turbine and diameter of the turbine. Also for each turbine, the minimum wind speed required to start the rotation and the speed it can rotate with varying wind speed will be determined. Three prototypes are created for testing purposes. Results showed that the increase the diameter of the turbine will reduce the rotation of the turbine. In addition higher number of blades will increase the rotation of the wind turbine

On the Avant-Garde IDeS Method for the Future of Car Design Applied to an SUV Project

This case study aims to develop a new innovative SUV (Sport Utility Vehicle) model exploiting IDeS (Industrial Design Structure), which is an engineering approach conceived to optimize car design projects in the automotive industry like never before. A compact SUV was chosen because it is a type of vehicle that is highly requested by customers, and it is extremely successful in the market due to its versatility. In fact, compact SUVs are mixed vehicles that combine the pragmatism of a car with the typical robustness of an off-road vehicle making them suitable both for urban and off-road scenarios. The following pages will illustrate the steps followed for the realization of the final product using the SDE (Stylistic Design Engineering) method and other various design technologies, such as Quality Function Deployment (QFD), Benchmarking (BM) and Top Flop Analysis (TPA). In the final part of this project, the virtual prototyping of the product is carried out using Additive Manufacturing (AM) with an FDM 3D printer. The combination of these methods forms, to all intents and purposes, the IDeS, a newly developed innovative and cutting-edge discipline capable of schematically guiding the new product development process in companies with unprecedented efficiency

This study is on the conception of the DS700 HYBRID project by the application of the Industrial Design Structure method (IDeS), which applies different tools sourced from engineering and style departments, including QFD and SDE, used to create the concept of a hybrid motorbike that could reach the market in the near future. SDE is an engineering approach for the design and development of industrial design projects, and it finds important applications in the automotive sector. In addition, analysis tools such as QFD, comprising benchmarking and top-flop analysis are carried out to maximize the creative process. The key characteristics of the bike and the degree of innovation are identified and outlined, the market segment is identified, and the stylistic trends that are most suitable for a naked motorbike of the future are analyzed. In the second part the styling of each superstructure and of all the components of the vehicle is carried out. Afterwards the aesthetics and engineering perspectives are accounted for to complete the project. This is achieved with modelling and computing tools such as 3D CAD, visual renderings, and FEM simulations, and virtual prototyping thanks to augmented reality (AR), and finally physical prototyping with the use of additive manufacturing (AM). The result is a product conception able to compete in the present challenging market, with a design that is technically feasible and also reaches new lightness targets for efficiency
