  • Virtual and Mixed Prototyping Techniques and Technologies for Consumer Product Design Within a Blended Learning Design Environment
    INTERNATIONAL DESIGN CONFERENCE - DESIGN 2018 https://doi.org/10.21278/idc.2018.0428 VIRTUAL AND MIXED PROTOTYPING TECHNIQUES AND TECHNOLOGIES FOR CONSUMER PRODUCT DESIGN WITHIN A BLENDED LEARNING DESIGN ENVIRONMENT M. Bordegoni, F. Ferrise, R. Wendrich and S. Barone Abstract Both physical and virtual prototyping are core elements of the design and engineering process. In this paper, we present an industrial case-study in conjunction with a collaborative agile design engineering process and “methodology.” Four groups of heterogeneous Post-doc and Ph.D. students from various domains were assembled and instructed to fulfill a multi-disciplinary design task based on a real-world industry use-case. We present findings, evaluation, and results of this study. Keywords: virtual prototyping, virtual reality (VR), augmented reality (AR), engineering design, collaborative design 1. Introduction Virtual and mixed prototyping within a collaborative blended learning environment is considered an enabling design support technique that allows designers to gain first-hand appreciation of existing or near-future conditions through active engagement with a wide variety in prototyping techniques and prototypes. The product design process (PDP) follows a dual approach and method based on a combination of a blended learning environment (Boelens et al., 2017) and interactive affective experience prototyping (Buchenau and Suri, 2000). The virtual prototyping summer school (VRPT-SS) facilitates this combinatorial collaborative setting to immerse learners in the externalization and representation of their ideas quickly, exploring and communicating their ideas with others. During the course of the week a series of evaluations on the prototyping progressions are made. The spectrum of virtual and mixed prototyping is quite extensive and has multiple definitions and meanings according to literature (see Wang, 2002, and Zorriassatine et al., 2003).

  • Practical Impacts of Design-Build on the Design Engineer
    Practical Impacts of Design-Build on the Design Engineer Presented by: Joseph C. Staak, Esq. Smith, Currie & Hancock LLP 2700 Marquis One Tower 245 Peachtree Center Avenue, NE Atlanta, GA 30303-1227 Tel: 404.582.8026 [email protected] www.smithcurrie.com November 2012 NOTES Practical Impacts of Design-Build on the Design Engineer I. INTRODUCTION Project delivery using Design-build has become increasingly popular over the last thirty years. Owners have recognized the advantages of using a single source of responsibility for a project’s design and construction. Many contractors have recognized the popularity of design-build and have made adjustments to their business model allowing them to offer this one-stop system for project delivery. Architects and engineers also recognize that, unless they want to avoid this ever growing segment of the project design market, they too must adapt to working directly with the contractor. Nearly half of all commercial construction in the United States is being awarded using design-build as the project delivery vehicle, and the reasons are obvious. Owners perceive multiple advantages in using design-build. These advantages include, but are not limited to, a single source of responsibility for design and construction, the increased risk design-build transfers to the design- builder, the opportunity to fast track design and construction to reduce the time from concept to completion, and the owner’s ability to take advantage of the design-builder’s expertise in identifying design solutions. Changes in public procurement during the last 20 years have precipitated an explosion in the use of design-build by government agencies.

  • Architectural and Engineering Basic Services Fee Negotiation Guidelines
    Architectural and Engineering Basic Services Fee Estimating Guidelines Basic Services is the design work customary on a typical project to take an established building program, site, and budget, and then develop the architectural design, engineer the building systems, produce construction documents, and perform construction administration for a single phase project. Basic Services include the design services customary on every project such as architectural, structural, civil, mechanical, and electrical engineering services. Basic Services are described in the Standard Consulting Agreement. The following method estimates the Basic Services fees using the Amount Available for Construction (AAC) from the established project budget. The fees are expressed as percentage of AAC for six (6) projects types with differing levels of complexity for both New Construction and Renovation. The Project Types are: Project Type I – Considerably Less than Average Complexity: Farm Structures, shop & Maintenance, Service, Warehouses, Storage Facilities, Parking Structures. Project Type II – Less Than Average Complexity: Student Housing, Office Buildings, Complex Parking Structures. Project Type III – Average Complexity: Classroom Facilities, General Teaching Spaces, Medical Offices, Clinics, Gymnasia. Project Type IV – More Than Average Complexity: Complex University Buildings, Engineering Laboratories, University Libraries, Dining Facilities, Theaters, Arenas, Auditoriums, Medical Schools. Project Type V – Considerably More than Average Complexity: Science and Medical Research Buildings, Hospitals, Museums. Project Type VI – Engineering Projects: Campus/Building Chilled Water, Steam, Fire Protection, or Hot Water Systems; Campus/Building Electrical Distribution Systems; Building Replacement Mechanical or Electrical Systems; Building or Campus Generator Systems; Campus Fire Alarm or Security Systems; Outdoor Lighting or Sports Lighting; Retrofit Building Fire Protection Systems; Campus Voice/Data Systems.

  • Design-Build by Zane Satterfield, P
    PUBLISHED BY THE NATIONAL ENVIRONMENTAL SERVICES CENTER Design-Build By Zane Satterfield, P. E., NESC Engineering Scientist Summary Design-build is a method of construction where the design and construction tasks are contracted with a single entity known as the design-builder or design-build contractor. The design-build meth- od is gaining popularity, with some projections indicating that more than half of all non-residential construction projects in the U.S. will be design-build by 2015. This Tech Brief discusses some of the aspects of the design-build method and how it might be used for water and wastewater projects. What is Design-Build? Design-build is a construction project delivery system where the design and construction as- pects are contracted with a single entity known as the design-builder or design-build contrac- tor. Design-build is more streamlined than the traditional method, often referred to as design- http://nats320.blogspot.com/ bid-build, where design and construction were clearly separated. The design-builder is usually the general con- Image courtesy of tractor, but can also be the architect or engi- neer. By incorporating the designer and con- tractor, design-build minimizes the project risk for an owner and reduces the delivery schedule by overlapping the design phase and construc- tion phase of a project. Rather than first bid- ding or engaging an architectural or engineering firm to design the project and then bidding out a contractor to build the project (i.e., the design- bid-build method), the design-build contractor packages the engineering design services in with The Washington National’s ballpark in the nation’s capital is one of the the construction.

  • What Is Design Engineering and How Should It Be Taught? – Proposing a Didactical Approach
    INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN ICED 05 MELBOURNE, AUGUST 15-18, 2005 WHAT IS DESIGN ENGINEERING AND HOW SHOULD IT BE TAUGHT? – PROPOSING A DIDACTICAL APPROACH Martin Grimheden and Mats Hanson Keywords: design education, definition of design, didactical approach 1 Introduction Design engineering is being taught at the Royal Institute of Technology (KTH) in the form of a Master of Science program, Design and Product Realization. The program started in August 2003, and has been rated so far by the students as the third most popular engineering program. Each year approximately 100 students are accepted. When the program was introduced by KTH, the subject of design engineering was chosen in favour of engineering design, with the purpose of establishing the program independently in relation to existing programs in mechanical engineering, vehicle engineering etc, and to establish the new program into the area of ‘development of attractive products’. The aim of this paper is to present results from a didactical analysis performed on the subject of design engineering. 1.1 Objectives Didactics is a field of educational studies mostly referring to research aimed at investigating what’s unique with a particular subject, and how the particular subject ought to be taught. The purpose of the didactical analysis is to identify and describe the identity and legitimacy of the subject (what is design engineering, and why should design engineering be taught?) as well as its implications on the educational methods (which material should be taught, and how?). The paper is structured as follows: In section two we describe the context of this study, providing a background and perspectives from research on education, the interpretation of the concept of design in Sweden and conclude with some examples of the industrial context of design engineering.

  • What Is Wrong with Reliability Engineering?
    What is wrong with Reliability Engineering? R.W.A. Barnard Lambda Consulting PO Box 11826, Hatfield 0028, South Africa Mobile : +27 82 344 0345 [email protected] Copyright © 2008 by R.W.A. Barnard. Published and used by INCOSE with permission. Abstract . Notwithstanding the implementation of reliability engineering programs by companies, it is not uncommon to observe many instances of low field reliability. This paper briefly describes the essence of reliability engineering, which has prevention of failure as primary objective. Possible reasons for the apparent failure of reliability engineering, especially as practised by the defence industry, are given. It argues that incorrect practices are often applied, frequently performed by incorrect people in the organisation, and at the incorrect time during the product or system life cycle. The value of reliability engineering as specialty area of systems engineering can be improved by learning from best practices used by industry leaders. The essence of reliability engineering —I believe that the concept of failure is central to understanding engineering, for engineering design has as its first and foremost objective the obviation of failure.“ Henry Petroski High field reliability is a highly desirable attribute of any product, system or plant. For defence products and systems, reliability may be the differentiating factor determining mission success or loss of life. For industrial systems and plants, reliability directly influences inherent availability and therefore return on investment. For commercial products, high reliability may provide a supplier with a competitive advantage, resulting in increased market share and therefore higher profits. In all cases, reliability of a product or system is strongly influenced by decisions made during the design and development process.
