2. Outline Engineering Design Cycle Problem Criteria & Constraints Background Possible Solutions Ideas Possibilities Approach Build Prototype Refine 3. EngineeringDesign Cycle 4. 1. Identify the ProblemBuild a continuously running fountain. 5. 2. Identify Criteria andConstraints Continuously and automatically circulateliquid Operate for several hours May incorporate either line-powered orbattery-powered pumps Footprint of the design is restricted to 2x2 6. Background Knowledge Laminar Flow straight line Transitional Flow slight fluctuation Turbulent Flow water fluctuates Surface Tension: Attractiveness of water on a surface. 7. 3. Brainstorm PossibleSolutions 8. 4. Generate IdeasOriginal Sketch 9. 5. Explore Possibilities Base: plastic bin, cooking pans, flower pots. Support: metal, wood, PVC pipe. Cups: ceramic, glass, plastic. Glue: caulk, JB Weld, hot glue, tape, cement. Decorative Elements: pebbles/rocks, paint, hemp rope. 10. 6. Select an Approach Initial design calledfor ceramic cups,not plastic. Plastic is easier towork with. Used JB Weld foradhesive. PVC pipe createdsupport. 11. 7. Build a Model orPrototypeNotice, the waterdoesnt flow tothe other cup. 12. 8. Refine the Design 13. Conclusion 14. Resources Munson, Bruce R., Donald F. Young, Theodore H.Okiishi, and Wade W.
