Olivia Nixon Dr. Crockett Engineering 110 23 November 2009 Design Lab Part 4, Build and Test 1. Prototypes: a. Suction cup with medium binder clip attached . We attached the binder clip directly to the suction cup by putting the round part of the binder clip around the small round part of the suction cup. Estimated Cost: Suction cup—35 cents, Binder clip—8 cents, Total—43 cents. b. Suction cup with medium plastic clip attached. We attached a medium white plastic clip (like a “chip clip”) to a suction cup with a rubber band. The rubber band was attached to the clip through a hole on the handle of the clip and was attached to the small round part of the suction cup. Estimated Cost: Rubber band —2 cents, Suction Cup—35 cents, Clip—50 cents, Total—87 cents. c. Suction Cup with large clip attached. We attached a large white plastic clip (larger “chip clip”) to a suction with a paper clip. We wrapped the paper clip around a hole in the clip and then around the small round part of the suction cup. Estimated Cost: Paper clip—2 cents, Suction cup—35 cents, Large Clip—75 cents, Total-- $1.02 d. Suction cup with binder slip attached using rubber band. With this prototype we implemented the rubber band from prototype “b” into the design for prototype “a”. We did this because we wanted to find the best solution possible. By implementing the rubber band we hoped to give what we thought was our best option with the binder clip more range of motion so it could serve more purposes. Estimated Cost: Binder clip—8 cents, Rubber band—2 cents, Suction cup—35 cents, Total—45 cents 2. Tests: a. First test: We submerged all of the components we were considering using in water for a full 72 hours. This test simulated the water that our product will come
