The Engineering Design Process
Transcript of The Engineering Design Process
A Process You Can Follow To Build a Successful Prototype
STEP 1: Identify the Problem
State the challenge problem in their own words. Example: How can I design a ____ that will _____?
STEP 3: Brainstorm Possible Solutions
Develop two or three ideas more thoroughly. Create new drawings that show top, front and one side, and isometric drawings. Parts and measurements should be labeled clearly.
STEP 5: Explore Possibilities
The developed ideas should be shared and discussed among the team members. Record pros and cons of each design idea directly on the paper next to the drawings.
STEP 7: Build a Model or Prototype
Construct a full-size or scale model based on your drawings. Identify and acquire appropriate modeling materials and tools.
Step 2: Identify Criteria & Constraints
Specify the design requirements (criteria). Example: Our growth chamber must have a growing surface of 10 square feet and have a delivery volume of 3 cubic feet or less.
List the limits on the design due to available resources and the environment (constraints). Example: Our growth chamber must be accessible to astronauts without the need for leaving the spacecraft
1) Identify the problem, needs and limits
2) brain storming & detailing ideas
Each student in the group should sketch his or her own ideas as the group discusses ways to solve the problem. Labels and arrows should be included to identify parts and how they might move. These drawings should be quick and brief.
STEP 4: Generate Ideas
STEP 6: Select an Approach
Work in teams and identify the design that appears to solve the problem the best. Write a statement that describes the best solution. This should include some reference to the criteria and constraints identified above.
3) Explore possibilities & Settle on an Approach
STEP 8: Refine the Design
Examine and evaluate your prototypes or designs based on the criteria and constraints. Have other groups review the solution and help identify changes that need to be made based on criteria and constraints.
4) Build a prototype, refine your design
