Class 9 – Sep 18 foundations of engineering design I Our Dental Processes, Functional Decompositions, Oral Presentation Prep today’s plan •pin up practice assignments •examine our processes •functional decomposition •professional oral presentations •quick online assessment •assignments & announcements engineering is all around us Prof. Lande goes to the dentist… think like an engineer. notice needs notice opportunities your dental hygiene routines pin up on the wall take a few minutes to look over the dental hygiene processes pinned up on the wall what are differences between them? what are some surprises? what are key needs you see for our culture’s dental hygiene? what are differences what are surprises identify key needs select another’s process brainstorm+sketch a way to save them time during the day functional decomposition electric toothbrush cleans teeth, but how? functional breakdown 1.

Visual Communication Engineering Tools Brainstorming Design Process Knowledge Design Process Application Description Visual Thinking 1 1 1 1 Attempt to Land Captain Fuchs aircraft was too high and too close to the airport to perform a landing so he was forced to circle the airport until he could reduce his air speed and altitude. In attempt to slow his aircraft he extended the flaps but only the inner wing flaps extended because the hydraulic system to extend the outer flaps had been damaged when the engine separated from the wing. This caused the wing to have a greater pitch angle when landing. The sudden drop in airspeed caused the plane to bank to the right. In an attempt to save the plane, Captain Fuchs increased the engine power, in turn dooming himself and the crew. pictures & graphics use them, but cite the source of and discuss them http://www.damninteresting.net/content/gertie_man.jpg animation/graphics are useful, but… • not all animation adds to the presentation • not all graphics add to the presentation 46 spll check miss pselled wrods and poor grammer is not aceptabel in a proffessional presentation! presentation wants • informative • quality references • knowledgeable / confident presenter informative how can you make your presentations informative? you’ll be presenting on manufacturing processes report out what are ways to make your presentation on a manufacturing process informative? share your team’s two best responses to the prompt informative • shows process at work • clearly discusses strengths/limitations of process • contains all requested info • asks for questions quality references how can you demonstrate the quality of the references in your presentation? report out how can you demonstrate the quality of the references in your presentation? share your team’s two best responses to the prompt quality references • reference list is presented • references include more than wikipedia and newspapers • quality of the references and/or authors is established confident speaker what are the characteristics of a confident speaker? report out what are the characteristics of a confident speaker? share your team’s two best responses to the prompt confident speaker • • • • exhibits enthusiasm makes eye contact points to items on screen delivers extemporaneous (not memorized) talk • doesn’t use note cards SolidWorks let’s you take your drawing to the next level. we’ll begin to get familiar with it in class next Tuesday. SolidWorks is linked to 2 course competencies installed on studio machines and in computer commons (CNTR 150). SolidWorks install to request access for installing it on your own PC, follow instructions on the URL below. it works on PCs or Macs with Boot Camp installed. this takes a little while to process, please do this soon. j.mp/getsolidworks http://ets.fulton.asu.edu/software/solidworks-and-cosmos quick assessment please get out your laptops or go to a classroom machine. follow the link below to complete a quick survey about a number of aspects of engineering design http://bit.ly/egr101studentsurvey https://asuengineering.qualtrics.com/SE/?SID=SV_6EfLp2JtC93R0LX assignments Practice Assignments PA 8: read/comment on article (due 9/20) PA 9: to be assigned this Thursday (9/25) PA 10: to be assigned this Thursday (9/25) PAs get posted on blackboard under assignments practice assignments Upcoming Competency Assignments CA 5: to be assigned this Thursday (9/27) CAs get posted on blackboard under assignments competency assignments announcement updated syllabus now on blackboard • mapping of competency points to grades fixed (now shows max of 13 points) • late work policy clarified (late work is not accepted for credit) • policy on resubmissions clarified • (we don’t take resubmissions)
