Write each question and use notes from yesterday
to answer.

• Before you can solve any problem, what are two
  things you must know?
• 2. During the research and brainstorm step of
  the design process, how can the creativity of the
  participant students be sparked?
• 3. When designing a solution, what do you do
  once youve settled on an idea to develop?

The Engineering Design Process

• PURPOSE OF LESSON

• To enable students to understand and apply the
  design process.

3
ENGINEERING DESIGN PROCESS

• Clearly Defined Steps
• Defining a problem
• Identifying criteria and specifying
  constraints
• Brainstorming
• Researching and generating ideas
• Exploring possibilities
• Selecting an approach
• Developing a design proposal
• Making a model or prototype
• Testing and evaluating the design, using
  specifications
• Refining the design
• Creating or making it
• Communicating processes and results

4
Step 1 Defining the Problem

• Describe the situation that needs a technological
  solution
• What must your solution accomplish?
• What is the need or desire?

Outcome Sentences, Paragraphs, Lists
5
Step 2 Identifying Criteria/Constraints

• Establish the criteria and constraints under
  which the solution must operate
• What are solution requirements (criteria)?
• What are the limitations on the solution
  (constraints)?

THIS IS A CHANGE
Outcome Sentences, Lists, Charts

Steps 3 4 Brainstorm/ Research/ Generate
Ideas

• 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?

Outcome Sentences, Paragraphs, Lists, Charts
7
Step 5 Exploring Possibilities

• Develop possible solutions to the
  problem/opportunity
• Come up with at least 3 solutions to the problems
  you must solve
• General sketches, then detailed sketches
• Does each satisfy the criteria and fit within the
  constraints?

PLAUSIBLE SOLUTIONS!
Outcome Sentences, Lists, Charts, Sketches
8
Step 6 Select an Approach

• Isolate, refine, and detail the best solution
• Modify
• Integrate components
• Improve
• Detailed sketches

Outcome Sentences, Lists, Charts, Sketches
9
Step 7 Develop Design Proposal

• An explanation of your final design
• Detailed drafted drawings
• Steps to make it
• Explanation of how it satisfies all criteria and
  constraints

Outcome Sentences, Lists, Charts, Sketches
10
Step 8 Make Model/Prototype
MUST GET PROPOSAL PASSED FIRST

• Make it!
• Prototype will be tested

Outcome Sentences, Lists, Charts, Sketches
11
Step 9 Test Model/Prototype

• Once you make your prototype, test it to ensure
  that it works. Also, calibrate your prototype to
  satisfy criteria and constraints.
• DOCUMENT YOUR TESTING
• PROCESS and RESULTS

12
Step 10 Refine the Design

• After testing in step 9, document any changes you
  need to make.

Step 11 Create/Make it

• Implement any changes decided upon in step 10.
  Prepare for the competition.

13
Step 12 Communicate Processes and Results

• Describe how the final solution meets design
  criteria and constraints.
• FINAL COMMUNICATION REPORT
