  1. MEEN 4263/64 Senior Design Fall 2013 – Spring 2014 Design Concepts

  2. What will we be doing? • 1 Lecture each week, 1 hr • Lab session, up to 3 hours or speakers • Dean says 3-5 team members, I have allowed a few with 6, no more than 6 students per team. • Status Reports of Projects • Conceptual Design Review – middle of October • Preliminary Design Review – end of Fall Semester (last regular class day or “Finals” day) • Mid-Semester Design Review– before/after Spring Break. • Senior Design Conference/ Critical Design Review – Late April 2014 MEEN 4263/64

  3. What is Engineering Design? • The use of math, science, and engineering knowledge, skills, techniques to create or modify an item such that the new or modified item meets or exceeds desired criteria in the most efficient manner. Poor design is “just getting by, or doing the minimum.” MEEN 4263/64

  4. What positions do you need? • Outside Mentor/Advisor • Project Leader • Chief Financial Officer (also may be chief weight/ load/ space officer) • Manufacturing Lead • Documentation Lead • Analyst Lead • Communications / Report Lead Prof. Peel will be your Program Manager MEEN 4263/64

  5. The Design Process • Get Project Notebook (Required!) • Develop Objectives • Brainstorm ideas based on objectives, trying not to be critical. • Conduct a literature search, continually refine. • Select best ideas and make a decision matrix. • Presentations from Industry… ask questions!!! Discussion on next pages…… MEEN 4263/64

  6. Brainstorming • Don’t be critical of ideas, lots of great products were “pooh-poohed” at first. • Use your objectives as your guides. • Get in a room with a chalk/white board, appoint a scribe, take an hour or two. • If a good idea comes, perhaps you change your objective? • Ask or try to explain your project to a non-technical person (mother, brother, wife, friend?) MEEN 4263/64

  7. Literature Search • Google, Google Image • Bing, Bing Image • Jernigan Library – Online Resources, Interlibrary Loan, Books, Journals • SCIRUS.COM (technical search) • Patent Searches (uspto.gov, see notes from Dr. Murphy) MEEN 4263/64

  8. Decision Matrices – Project (Cribbing Group) MEEN 4263/64

  9. The Design Process Cont’d • After you have some basic ideas……. • Conduct preliminary calculations • Select materials • Select configuration • Make Technical Drawings • Conduct analyses and optimization • Revise Technical Drawings • Fabricate & Test prototype • Repeat the process • Presentations from Industry… ask questions!!! MEEN 4263/64

  10. What is a Technical Drawing? • It is a professional-level drawing that has enough info for a qualified machinist/ fabricator/technician to fabricate what you have designed. From: www.cadster.co.uk/index.html MEEN 4263/64

  11. Resources from the Book! Ch 1: Engineering Design Ch 2: Product Development Process Ch 3: Problem Definition and Need Identification Ch 4: Team Behavior and Tools Ch 5: Gathering Information Ch 6: Concept Generation Ch 7: Decision Making and Concept Selection Ch 8: Embodiment Design Ch 9: Detail Design Ch 10: Design for Sustainability and the Environment Ch 11: Materials Selection Ch 12: Design with Materials Ch 13: Design for Manufacturing Ch 14: Risk, Reliability, and Safety Ch 15: Quality, Robust Design, and Optimization Ch 16: Economic Decision Making Ch 17: Cost Evaluation Ch 18: Legal and Ethical Issues in Engineering Design (available online) • Definition of Design • Engineering Ethics • Project Management • Modeling & Simulation • Material Selection • Stress Analysis • Engineering Economics, cost analysis • Design Optimization • Statistics, Statistical decisions • Reliability • Safety MEEN 4263/64

  12. Detailed Design • You should have good technical drawings now.. • Preliminary & Detailed analyses? • When simulated, does the design work? • Can you fabricate it as designed? • Is the cost reasonable? • Detailed drawings, exploded views, other? • List of needed materials, • Machine shop work? MEEN 4263/64

  13. Weekly Status Report/Assignments • Fill in names, team roles, email, cell # • Make sure you have a valid Team Mentor/ Consultant (technical background) • Describe current work, list problems, concerns • List next week’s objectives, list of materials needed, etc. • Team leaders should fill out status report each week, write the tasks each person will do, follow up on each task. • Each team member should know what their tasks are each week, and be prepared to report on them, at weekly meetings. • Let me know of needed materials, 3D printing, etc well before needed dates. MEEN 4263/64

  14. Time Management Assignment • List 5 things you can do to improve your time management. • Write about what you have done to implement each of them. MEEN 4263/64
