Date: 5/25/16
Define the Problem Develop a problem statement that identifies the what, who, when and how the problem should be addressed.
We have been hired by a local museum to design an interactive Rube Goldberg exhibit for visitors to learn about Rube Goldberg, simple machines and core technology. We need to make the exhibit fun and informational, the museum wants our device to use a wide variety of core technologies and simple machines in creative and interesting ways. We need accomplish watering a plant. 2. Brainstorming Sketch five possible subsystems that you might use in your final design to meet the criteria and constraints of the design challenge. Clearly identify and describe how each of these ideas uses core technologies and simple machines.
3. Research and Generating Ideas In the space below, document your research. Be sure to include proper citations at the end of your notes.
Notes: Mechanical : Toy car Biotechnology: Plants Structural technology: Wood frame Fluid technology: Water Material technology: Plastic pipe Inclined Plane Pulley

4. Identifying criteria and specifying constraints
What are the criteria and constraints of the design problem? Criteria Constraints Constructed from materials provided by At least 5 out of 9 core the teacher and one item from home technologies must be used Cost should be minimized At least 2 subsystems Safe to operate Must complete the task between 1 -3 minutes Device cannot be touched or altered during process Must fit within a 24” wide x 24”
long x 18” high volume Materials List: Based on your brainstorming and the criteria and constraints, list the materials you plan to use to meet the design requirements. 1 Live plant Toy Car Wood pieces to the platic piping Water bottle to use so we can water the plant Paper towel and tolet paper roles Hot glue Guns String Fabric
5. Exploring possibilities Reflect on your brainstorm ideas and research notes and describe the plusses and minuses of each design approach you have considered. Brainstorming Idea
Pluses
Minuses
More wood componets
The wood will get wet after the first test run
Idea 2
Toy car leading the water
The car could more off track and make the water run off corse
Idea 3
Pipe to lead the water in pot
The pipe could lead the water on the ground
Idea 1
Did alternative solutions arise as you initially evaluated your designs? Cite examples.
Instead of using wood frames the entire time we could use pipes to lead the water so the wood doesn’t become soggy.
4. 6. Selecting an Approach a. Enter the constraints and criteria of the project in the first column. b. Score your brainstorming ideas against each constraint or criterion and indicate how well the idea meets the criteria and constraints. 3 pts = easily meets, 2 pts = somewhat meets, 1 pt = does not meet c. Total the columns and circle the highest score to indicate your best design idea. c. Write a short paragraph justifying your solution. Include trade-offs that were made in the selection.

We are choosing brainstorming idea 3, we are choosing it becasue it meets all of the constraints and criteria and it had the highest score.
7. Developing a Design Proposal Take your highest scoring brainstorming ideas and create working drawings (sketches with dimensions, so that you could build your project) of your complete device. Attach your working drawings to this sheet. In addition to the drawings in your design proposal, use the material type and cost data in the design brief to predict the cost of materials for your device. , the customer wants to keep the cost of the device down as much as possible. The following table will help you organize your cost data and calculate a predicted cost before you build. Material to be Used live plant

9. Testing and Evaluating the Design, using specifications As you create your solution, you will perform tests to make sure that the solution is meeting the needs of the given problem. If your solution does not work, you may need to repeat the previous steps of the Engineering Design Process, until you find a functional design. In the space below, document the type of tests you conducted and the results. Test Performed
At least 5 out of 9 core technologies must be used
At least 2 subsystems
Must fit within a 24” wide x 24” long x
Test Results We included 5 out of 9 core technologies in the project.
We included2 subsystems in the project.

10.Refining the Design Based on your tests, what design refinements should be made to the prototype to ensure that it can satisfy all of the criteria and constraints of the design problem. We had to refine the materials we had by making them stronger and sturdier with tape. We also had to completely remove the marbles form the porject because they weren’t working like we wanted them to so instead we just used the water.
11.Creating or making it Modify your model/prototype to incorporate the design refinements you identified in section 10. Document the construction of the model/prototype. Be sure to include sketches/pictures as appropriate. Construction in Process

e. Mechanical Advantage Calculation To meet specifications, your final device should have included at least 2 simple machines. Examine one of the simple machines used in your device and calculate the mechanical advantage (MA) it creates. Be sure to show all your work and the actual measurements you obtained from your device. Refer to the mechanical advantage worksheet we went over in class for examples of how to calculate MA for various simple machines.
