Need help with an engineering hw.

all instructions are down bellow. really need an A with the class.


ENGR 111                        HW ASSIGNMENT #7 – 10


Design Project


Objective :


The objective of this assignment is to develop an understanding and appreciation for the complexity of the engineering design process, and to experience the thinking processes required by performing a small design project. This is a group project, work in groups of 2-4 students.


Potential projects: Develop a device to measure the pressure as a function of depth in water. Develop a device to measure temperature Develop a device to measure time. Develop a device to measure weight. To do a different project, you must get instructor approval.

To get full credit, all projects listed above must not use any store bought parts or electronic parts that perform the measurement you are interested in.


The design process that you will formally follow for the purposes of this project is listed below. If you feel the order doesn’t match what your group thinks is best, you can adjust accordingly.


1 – Identify the problem/product innovation –  your group will choose one of the design projects listed above.

2 – Define the working criteria/goals –  based on the project you have chosen, come up with at least 5 decision criteria that you think would be good criteria to judge the final design on.  Also put down weights for each criteria that you think seem reasonable.  Clearly define what a score for each criteria means.

3 – Research and gather data –  gather any background information you think is relevant, if necessary.

4 – Brainstorm/generate creative ideas –  hold a formal brainstorming session with your group.  The goal is as many ideas as possible, no judgement. Do not get hung up in “solution space”, just put the general idea down.

5 – Analyze potential solutions –  narrow your ideas down to 2-3 that seem the most promising based on your “engineering judgement”. Now is the time to go into more detail on some specifics of certain ideas, if they are potential candidates.

6 – Develop and test models/feasibility –  create models for each of your potential solutions. Generate different tests to perform.  For the purposed of this project, at least 3 tests need to be performed for each model you are testing. Remember section 3.9 in the book. (Example: you are developing a device to measure time, test each design at 10 seconds, 30 seconds, and 120 seconds) More tests may be prefered depending on your specific situation (60 seconds, 10 minutes, 1 hr… What are your criteria?).  Perform the tests and record your results.

7 – Make the decision/evaluation and selection –  based on the decision criteria you generated, decide which design to go with. If none of your designs seem to be adequate, try one more design from your brainstorming session before moving on to the communication phase.  Additionally, if items came up during testing that made you want to change your decision criteria, this is a reasonable thing to have happen. Be sure to make note of what is changing and why.

8 – Communicate and Specify – Generate a report  to sell your idea.  Be sure to include the  test results of all the models you tested,  and  why the final model is the one being chosen .  To really sell your idea, think about why someone would want to use this product and specify why the final choice meets those criteria.  

9 – Implement and commercialize – not for this project

10 – Post-implementation review and assessment – not for this project


For this project, you will be focusing on #’s 1-8.


What needs to be turned in:

Your group needs to keep a  project notebook  to be turned in with your  final report .  Only one copy of each for the entire group is needed.  

Project Notebook (20 pts): I am grading you on how you followed the design process outlined above, this notebook is how I will determine that.  Take notes appropriately. One way to take care of the project notebook is to designate 1 person to be the official note taker at each team meeting, rotating this role, and keep all the notes together. Another way to take care of this: if someone is a great note taker, they can volunteer to take all the notes. At the group’s discretion this person might not be required to do any of the final write up, or a reduced amount. The project notebook will constitute 50% of the total project grade, so don’t take it lightly. This is where you make note of all the items listed in the table above. It is common practice in engineering to have a notetaker for meetings, and to keep record of important proceedings. This is to prepare you for that. Before turning the notebook in, review your notebook and add additional notes for clarification. If I can’t understand what you meant, I can’t give you the best grade possible.  If I don’t see you doing a particular step based on your notebook, I will deduct points.

Final Report (20 pts):

 A suggested format is available in your textbook, pg 100. Be sure to include the test results of all the models you tested, why the final model is the one being chosen, and why the others are not being chosen To really sell your idea, think about why someone would want to use this product and specify why the final choice meets those criteria.   Make your final report easy to follow, and professional looking. If your report isn’t organized well, it isn’t taken seriously by readers, and might not move on in the approval process.
