1. Engineering H193 - Team Project Gateway Engineering Education Coalition Modeling By: David Hawn Week 2 Day 3

2. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 2Spring Quarter Modeling What is a Model? Why should your group think about creating a model?

3. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 3Spring Quarter Models can be: Drawings Equations Numerical Simulations Mock-ups Prototypes

4. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 4Spring Quarter Drawings Sketches CAD Key AutoCAD Solidworks ProEngineer Inventor

5. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 5Spring Quarter Equations Graphically Analytically

6. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 6Spring Quarter Numerical Simulations MATLAB - Simulink Maple Excel On-purpose software applications

7. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 7Spring Quarter Mock-ups A physical model of an idea to show the spatial relationship of parts. Not fully functional Not necessarily to scale Not necessarily fully complete

8. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 8Spring Quarter Prototypes The first fully functional and full scale representation of a design. -Tools and Tactics of Design

9. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 9Spring Quarter Purpose of Modeling Gives you the ability to test, prove, and (sometimes) disprove the feasibility of ideas Better understand the problem Refine your concept Prove to yourself and your group that an idea will work Fewer mistakes later Helps avoid wasting time and money

10. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 10Spring Quarter My Model Is it a prototype or a mock up?

11. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 11Spring Quarter Part Mock-up - Part Prototype Only the pickup mechanism was completely prototyped. The Mock-up / Prototype was continuously revised until the final working model was completed. The Mock-up / Prototype was produced using cheap materials that were quickly and easily modified and changed.

12. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 12Spring Quarter Parts and Materials Two primary sources of parts and materials for most projects: –Parts can be purchased commercially –Someone within your group can design and manufacture them.

13. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 13Spring Quarter Purchased Parts Parts can be found at Wal-Mart, craft shops, bike shops, flea-markets, hardware stores, FEH store, the kitchen cabinet, from your closet.... Purchased parts can be used for a purpose other than what they were originally manufactured for, or they can be modified. Purchased parts can easily be replaced.

14. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 14Spring Quarter Manufactured Parts Likely will take more time Can more specifically meet your needs Difficult to replace Can require a great deal of technical skill Can be much cheaper than purchased parts

15. Engineering H193 - Team Project Gateway Engineering Education Coalition P. 15Spring Quarter Examples of Materials for Mock-ups and Prototypes Erector Sets Legos Popsicle sticks Welding rod / coat hangers Cardboard Hot glue Solder
