1. The Engineering Design Process
Presentation 2.1.1

2. NASA Design Process Model

3. Identify the Problem
Example:
A device is needed that would allow a person with rheumatoid arthritis to open jars with different size lids

4. Develop a Design Brief Identify Criteria and Constraints
Criteria-What exactly should the device do?
Constraint-What should it not do?

5. Use a KWL chart What information must we locate? Perform the research
Gather Information
Use a KWL chart
What information must we locate?
Perform the research

6. Brainstorm Alternative Ideas
All ideas are ok
This begins the creative part
Any format is ok. (words, sketches)

7. Decide on the Final Design
Narrow down the possibilities
Decide on the best idea
Justify the idea

8. Perform Developmental Work
Create sketches & formal documents.
Test ideas and materials

9. Follow your plans & drawings Revise if necessary during prototyping
Build the Prototype
Follow your plans & drawings
Revise if necessary during prototyping

10. Test and Evaluate Does it work as anticipated?
Does it meet all criteria and constraints?

11. Redesign or Refine If it works, improve it.
If it doesn’t work, redesign it.
What went wrong? How can we fix the problem?
