3. Engineering
Design
Cycle

4. 1. Identify the Problem
Build a continuously running
fountain.

5. 2. Identify Criteria and
Constraints
 Continuously and automatically circulate
liquid
 Operate for several hours
 May incorporate either line-powered or
battery-powered pumps
 Footprint of the design is restricted to 2’x2’

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 Possible
Solutions

8. 4. Generate Ideas
Original 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 called
for ceramic cups,
not plastic.
 Plastic is easier to
work with.
 Used JB Weld for
adhesive.
 PVC pipe created
support.

11. 7. Build a Model or
Prototype
Notice, the water
doesn’t flow to
the other cup.

12. 8. Refine the Design
