  30. 30. Syllabus Questions E-mail the answers to the questions at the end of the syllabus to me Grades will not be posted on Blackboard until I receive the answers
  31. 31. The Worldwide Graphic Language for Design(Chapter 1)
  32. 32. Technical Drawing Used to communicate ideas Universal Language Takes teamwork to put together a set of drawings Technical Drawing are drawn by  Engineers  Architects  Drafters  Designers  Manufacturers  Technicians
  33. 33. TECHNICAL DRAWINGTechnical drawings serve one of three purposes: • Visualization • Communication • Documentation (Courtesy of Seymourpowell.) (Courtesy of Woods Power-Grip Co., Inc.) (Courtesy of Dynojet Research, Inc.)
  34. 34. Technical Drawing Example Professions that use technical drawings  Civil Engineering  Mechanical Engineering  Electrical Engineering  Architecture  Bio-resource Engineering  Landscape Design  Industrial Design  Construction Engineering & Technology  Patternmaking  Project Management  Fabrication  Manufacturing
  35. 35. Why draw by hand? Small Projects Back and forth exchange of ideas (Concept Drawings)  Engineer  Client  Engineer Mark-up  Final Refining Consensus Building Better understanding of how to draw
  36. 36. Artistic vs. Technical Drawings Artistic drawings are used to express aesthetic, philosophic, or other abstract ideas. Technical drawings are functional drawings to represent the design of objects to be built or constructed
  37. 37. Computer-Aided Design and Product DevelopmentComputer Aided Design (CAD)Computer Aided Engineering (CAE)Computer Aided Manufacturing (CAM)CAD allows for a range of activities, frommodeling 2D and 3D geometry to creatingdrawings that document the design formanufacturing and legal considerations.CAE allows users to simulate and analyze structures that will be subject to various temperatures, staticloads, or fluctuating loads.CAM provides computerized control for manufacturing processes.
  38. 38. Drawing Example Blocks!
  39. 39. Design Process1. Problem identification: First, a clear statement of the need for and objectives for the design must be written.2. Ideation (Concepts and Ideas): Technical sketches are often used to convey concepts to multidisciplinary teams.3. Refinement/analysis (Comprise Solutions): Designs may be rethought, based on engineering analysis. CAD models and sketches are useful during the analysis and compromise stage. Accurate 2D or 3D CAD models and drawings are created to refine the design.4. Implementation/documentation (Creation of Models & Prototypes): Production and/or working drawings providing the details of manufacture and assembly are finalized and approved.
  40. 40. ENGINEERING DESIGN STAGE 1 Identify the Customer and the ProblemThe engineering design process beginswith recognizing or identifying theseneeds and considering the economicfeasibility of fulfilling them. A successful design must not only solvethe problem but also meet the needs andwishes of the customer. (Project developed and created by Philips Design.)
  41. 41. ENGINEERING DESIGN STAGE 2 Generate ConceptsDuring this stage, often called the ideation stage, many ideas—reasonableand otherwise—are collected.The ability to freely createtechnical sketches lets youpresent and share ideas andrecord them so you can referto solutions, inspirations, andbreakthroughs that come tolight during this creative stageof the process. (Courtesy of Seymourpowell.)
  42. 42. ENGINEERING DESIGN STAGE 3 Compromise SolutionsThe design teamselects various featuresof the conceptsgenerated in theideation stage andcombines them into oneor more promisingcompromise solutions. 2D CAD Drawing. (Courtesy of Seymourpowell.) Many of these problems are solved graphically, using schematic drawings in which various parts are shown in skeleton form. For example, pulleys and gears are represented by circles, an arm by a single line, and a path of motion by centerlines
  43. 43. ENGINEERING DESIGN STAGE 4 Models and Prototypes Design teams often construct a model to scale to study, analyze, and refine a design. 3D CAD Model. This 3D CAD model of a design for the Mars rover was constructed to act as a virtual prototype for the design. (Courtesy of Byron Johns.)3D CAD Model of the SAAR Brake. (Courtesyof Dynojet Research, Inc.)
  44. 44. ENGINEERING DESIGN STAGE 5 Production or Working DrawingsThe drawings, showing thenecessary views, includethe material, dimensions,required tolerances, notes,and other informationneeded to describe eachpart sufficiently for it to bemanufactured consistently.These drawings of theindividual parts are alsoknown as detail drawings. Detail Drawing for the SAAR Brake Air Can Mounting Bracket. (Courtesy of Dynojet Research, Inc.)
  45. 45. Design Process Activity The design process helps engineers, technicians, and other problem-solvers come up with creative solutions. You are an engineer. Choose ONE engineering problem below, and follow apply the design process steps to invent a solution.  A. Your new pet kitten is trapped in a ten foot deep hole. You need a contraption to safely rescue your poor animal.  B. You are going on vacation for a month and can’t find anyone to water your plants while you’re gone. You need a device that will give your plants the right amount of water – not too much and not too little.  C. You like to read before you go to sleep, but you don’t have a bedside lamp. You need a way to turn off the light switch across the room without having to get out of bed.
  46. 46. Evaluation and Extension: 1. What problem did you choose? Brainstorm ways to solve the problem and list several possible solutions. 2. Choose one idea. Draw a detailed picture of the solution you chose. Label the drawing to explain what each part is made out of, how the parts fit together, and how it will work. 3. Where do you think you will run into problems with your solution? Where do you think the weak parts in your creation will be?
  47. 47. Concurrent EngineeringTraditionally, design and manufacturing activities have taken place in sequentialorder rather than concurrently (simultaneously). This step-by-step approachseems logical, but in practice it has been found to be wasteful. Concurrent engineering is a systematic approach that integrates the design and manufacture of products with the goal of optimizing all elements involved in the life cycle of the product. The Concurrent Process
  48. 48. Life Cycle DesignLife cycle design means that allaspects of a product (such as design,development, production, distribution,use, and its ultimate disposal andrecycling) are consideredsimultaneously.The basic goals of concurrentengineering are to minimize productdesign and engineering changes and toreduce the time and cost involved intaking a product from design conceptthrough production and ultimately tointroduction into the marketplace.
  49. 49. Assembly DrawingsAn assembly drawing, shows how all the parts go together inthe complete product. Assembly Drawing for the SAAR Brake. (Courtesy of Dynojet Research, Inc.)
  50. 50. DRAFTING STANDARDSThere are standards that support a uniform, effective graphic language foruse in industry, manufacturing, engineering, and science.In the United States, providing thesestandards has been the work of theAmerican National Standards Institute(ANSI) with the American Society forEngineering Education (ASEE), theSociety of Automotive Engineers (SAE),and the American Society of MechanicalEngineers (ASME).International standards, often defined bythe International Organization forStandardization (IOS), and the ASME orANSI standards for drawing practices aresimilar in many respects.
