CHAPTER 2: Preliminary design project. Engineering Design and Problem Solving. Introduction/Description.
Engineering Design and Problem Solving
Introduction to Engineering Design Process
Defining the Problem and Coming up with a Solution
Applying Logic, Finishing the Job and Communicating the Solution
Using the nine-step engineering design process (EDP), you will complete six student challenge problems.
Complete the Engineering Design Process Activity Mat.
Use a compare and contrast graphic organizer to compare and contrast the scientific process versus the engineering process.
Identify the Problem
What is the problem in this scenario?
The zoo wants a structure that connects the two monkey buildings and allows the visitors to view them as they cross.
Determine Goal for Problem Solution
Determine Design Parameters
Establish and Evaluate Constraints
Identify Solutions to the Problem
Research the problem and put together several monkey bridge designs, making sure that all of the parameters and constraints are addressed and the goals are met.
Test and Evaluate Solutions
Review each of the bridge designs. Run computer simulations, build and test scale models, and run experiments.
Evaluate Chosen Solution
Using the results from tests and experiments, choose the most viable bridge design.
Choose and Justify a Solution
Test the chosen bridge design against the goals, parameters, and constraints.
Communicate the Solution
Here are some examples of how to communicate the chosen solution to the problem.
NASA and other government websites have resources that can assist you in this process.
Through out this class, we will be referring back to the engineering design process as we work through our varying projects.
A manufacturer sees the need for a portable, collapsible, lightweight device that can give shade during hot weather to a variety of living things and objects, such as animals, humans, plants, and construction materials, for an indefinite amount of time.
What is the problem(s) in this scenario?
The engineer might ask these questions of the shading structure manufacturer:
where PV is the present value of the amount invested; Pt is the dollar value of the future amount in time t; r is the discount rate; and t is the year in which Pt is realized.
