With 1 partner:
Get out last night’s homework and critique the paper layout for correct formatting.
Go through your assignments and critique them:
What was done well?
What needs improvement?
Take notes on what you can do to improve at the bottom of the homework assignment (notes must be legible, but not lettered).

Design Process
Design Principles
Design is the result of a formal, sequential process.
Design is mostly driven by profit motive and market.
Design is the result of goal-oriented research.
Designs must be continually checked, refined, and improved.
Note:
Design problems seldom arise in a clearly defined form.
Design requirements sometimes compete with each other.

6. Design Process I1-4 Clearly Defined Steps: Clearly Defined Steps:

Identify criteria and specify constraints
Brainstorm
Research and generate ideas
Explore possibilities
Select an approach
Develop a design proposal
Make a model and/or prototype
Test and evaluate the design
Refine the design
Create the final product
Communicate processes and results

Design Process as you should know it:
Define the Problem
Brainstorm, Research, Generate Ideas
Explore Possibilities
Develop a Design Proposal
Make Model/Prototype
Test and Evaluate
Refine the Design
Communicate the Solution
Next: an outline of these steps of the Design Process – use this all year

9. Outcome: Sentences, Paragraphs, Lists
IOT POLY ENGINEERING
I1-4
Define the Problem 1
Describe the situation (that needs a tech. solution)
What must your solution accomplish?
What is the need or desire?
Establish the criteria and constraints under which the solution must operate
What are solution requirements (criteria)?
What are the limitations on the solution (constraints)?
Outcome: Sentences, Paragraphs, Lists

10. Brainstorm, Research, Generate Ideas
IOT POLY ENGINEERING
I1-4
Brainstorm, Research, Generate Ideas 2
Gather information –
Obtain background information needed to begin developing solutions to the problem/situation
What specific information do you need to know prior to designing your solution?
What criteria/constraint details must you be informed about?
Create several design possibilities
Outcome: Sentences, Paragraphs, Lists, Charts

11. Explore Possibilities
IOT POLY ENGINEERING
I1-4
Explore Possibilities 3
Develop possible solutions to the problem / opportunity
Come up with at least 3 solutions to the problems you must solve
Include general sketches, then detailed sketches
Does each possible solution satisfy the criteria and constraints?
PLAUSIBLE SOLUTIONS!
Outcome: Sentences, Lists, Charts, Sketches

Classwork / Homework
In complete sentences, explain how the four design principles can be used to evaluate a design and how the principles are applicable to the engineering design process.
Study everything covered in this class so far, including paper setup – quiz likely.
When the first bullet is read, mention a bunch of common technologies so that students can’t take an easy way out. For example, say, “iPod, t.v., cell phone, car, video games, computers, internet.” It frustrates them and will get them thinking outside their usual box.
