  1. ME4000 Oct. 4, 2006

  2. Agenda • Upcoming Presentations • Benchmarking • CFP • Individual wiki reports • Design refinement and COTS parts (covered in detail in lab 6) • Design Selection (with more detail covered in labs 6 and 8) • Sys. Config  SRR (covered in lab) • Grades (will be posted this afternoon)

  3. Technical Feedback & Presentation Guidance • Benchmarking • Critique benchmarked products & designs • Sources • General comment on figures • Critical Function Prototype (CFP) • What makes a good CFP? • What you should present in coming weeks

  4. How & What You Should Benchmark • Look at closest competitors • Look at devices with related functions, markets, or components. • Evaluate the products you find!!! • Pro’s / Con’s • Is it a good product? • Why? Why not? • You are the expert, tell us what you think

  5. Benchmarking Coleman Space Heater Pros: • Large heat output (3000 Btu) • Catalytic converter • Inexpensive • Relatively portable Cons: • Toxic fume output • Open flame • Too big for backpacking www.coleman.com [Slide borrowed from Backpacking Heater 2nd update presentation]

  6. Benchmarking Zodi Tent Heater Pros: • Heat output (20,000 Btu) • Fume separation • More fuel = longer heating time Cons: • Size/Portability • Expensive ($260.00) www.zodi.com www.zodi.com [Slide borrowed from Backpacking Heater 2nd update presentation]

  7. Sources for Benchmarking • Web • Library • Stores & Junkyards • Go touch some hardware (you’ll get ideas) • Robotic parts  go to a toy store • Camping products  go to REI • Aircraft  go to a hobby shop • Remember, you’re never really done benchmarking

  8. General comments on Figures Super-duper Coleman Heater • Put titles on your figures (easier to reference) • Label the important things on your figures • Make sure to cite (even yours) • Example shown on right Propane tank Diffuser Optional Stand www.coleman.com

  9. Critical Function Prototypes • What makes a good CFP? • Something you’ll learn from • Perhaps a risky design that could reap rewards • Preferably something physical • Something non-trivial / non-obvious • Something that represents about 2 team-weeks effort • Good approach is to list components in design and their functions and assess risk associated with each

  10. Content of Benchmarking Presentation • Time: 8–10 minutes • Preview/Outline Slide • key dates in your schedule (very brief, 1–2 slides) • reference your current progress • ahead or behind on your schedule • what is the next thing(s) your team is focusing on? • Budget (1 slide max, very brief) • How are you doing, spending, projected spending, fund raising… • Misc. updates • Only if you have time, these should be important if you include any <3 minutes

  11. Content of Benchmarking Presentation • Benchmarking • especially cool stuff you found that you may use • include designs you can adapt from outside your immediate project area (e.g., Mini Baja would probably want to look at ATVs, snowmobiles, dune buggies…) • What will be your team’s Critical Function Prototype (CFP). • If you are unsure, please present the 2 or 3 options you are considering. • Motivation and goals for choosing this CFP • What you will learn by doing this CFP • Review/Summary Slide • Time: 8–10 minutes 3-5 minutes

  12. Content of CFP Presentation • Time: 8–10 minutes • Preview/Outline Slide • key dates in your schedule (very brief, 1–2 slides) • reference your current progress • ahead or behind on your schedule • what is the next thing(s) your team is focusing on? • Budget (1 slide max, very brief) • How are you doing, spending, projected spending, fund raising… • Misc. updates • Only if you have time, these should be important if you include any <3 minutes

  13. Content of CFP Presentation • Describe chosen CFP, reminding audience what you hoped to learn from making it. • Bring CFP to class if possible and show audience • Describe what you learned, surprises, failures, etc… • Take pictures and label the important things you want to show us • Review/Summary Slide • Time: 8–10 minutes 5 minutes or more

  14. Individual Wiki Report • 10% of your final grade • Design development cycle for your “thing” • Collection of lab assignments + writeup • Lab 3 – brainstorming and sketching ideas • Lab 6 – initial downselect andCAD refinement utilizing COTS parts • Lab 8 – design selection (trade matrix), associated calculations and data/part sources, and assembly drawing

  15. Individual Wiki Report • Writeup • Problem definition and summary • Requirements • Specifications • Concept generation and sketches (lab 3) • Initial downselect & design refinement (lab 6) • Final selection, supporting calculations or data, and assembly drawing (lab 8) • Conclusions

  16. Agenda • Design refinement and COTS parts (covered in detail in lab 6) • Design Selection (with more detail covered in labs 6 and 8) • Sys. Config  SRR (covered in lab) • Grades (will be posted this afternoon)

  17. Grades • Labs • 15% of final grade, • 25% of this attendance • Check plus = 125 unless otherwise noted • Check = 100 unless otherwise noted • Check minus = 75 unless otherwise noted • Check minus minus = 60 unless otherwise noted • Most grades in this range: 75-100

  18. Grades • Presentations (10% of final grade) • Grade range 60-100 • The current majority now have 80-85 • If you are below 80, you could use some improvement • If you are 85 or above, you did well • Last year most final grades were 75-95

  19. Grades • Writing assignments • Memos (All memos count towards 10% of final grade) • Individual grade • Graded by Marlin • mostly check or check-minus (75 - 100) • Executive summary Final draft Ave ~ 84 • Team grade – mostly high grades • No Signature  25 • Deliverables Memo Ave ~ 84 • List of deliverables + schedule  100 • No list of deliverables  50 • No Signature  25

  20. Grades • Project Grade (35% of total grade) • Advisor Grade 20% • I am asking for an interrum grade from your advisor Wednesday next week • Intra-Team Grades 15% • I am asking for an interrum grade from your team mates by Wednesday next week

  21. Project Grade • Intra-Team Grading • Grade sheet will be posted • Fill out form, 1 for entire team • If giving entire team same grade, you are done • If giving someone a lower grade, fill out a detailed individual form for that person only (in addition to the main team form) • Due by next Wednesday
