Engagement

The Dragon is a free-flying, reusable spacecraft developed by SpaceX under NASA's Commercial Orbital Transportation Services (COTS) program. The Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members.

What steps do you think were followed to create such an amazing innovation.

• You will be given a set of index cards with different steps of a problem solving process.

• With a partner, organize the steps in the order that you feel an Engineer would go through to solve a problem.

• Be prepared to defend your sequence of steps

Exploration

• How did you do?

• What order did you put the steps?

• When called – come to the front board and put the steps in the order that you think an Engineer would go through to solve a problem.

• Defend your order.

Explanation

1. Design problems are not always presented in a clearly defined form.

2. There are many formal and informal problem-solving strategies.

3. There are established design principles that are used to evaluate existing designs, to collect data, and to guide the design process.

4. The Engineering-Design process is a step-by-step problem-solving strategy

1. It includes criteria and constraints

2. It can be used to create solutions to problems to satisfy human needs and wants.

•The Scientific Method is very important.

•Gives us answers to the way the Universe works

•It is linear in nature.

•It has a starting point and ending point.

•Once you report your results, you can then form a new question.

Explanation

The Design Process is a circular process- it encourages changes and improvements.

Explanation

Our Problem Solving Process

Explanation

1. Define the problem.• What is the problem that you are trying to solve?• Not all problems will be clearly defined.

 Problem Statement:            The products that we buy in the store are packaged in many unique ways to insure that they arrive at the specified location without being damaged.    Design Brief:             Design and construct a package that will protect a raw egg from being damaged when dropped from a height.

What problem are we solving?

Explanation

2. Brainstorming.• Create a list of ideas• Sketch simple concept pictures• Work towards quanity• Never criticize anyone’s idea• Use “Mind Mapping”

•Lets give this a try.•List possible ideas•Mind Map•Make at least three different sketches

Explanation

3. Research and generate ideas• What have others done?

• What do you need to know? – science, math concepts

– Look on-line

• As you look at what others have done – do you have any more ideas?

Cite your sources!

Google is not a source! It is a search engine.

Explanation

4. Identify criteria and specify constraints• Now that you know the Problem and some information, it

is time to look at what the requirements are.• This will include:

– People, Time, Materials, Tools, Cost and other factors

•This is an individual project.•You will have three days to build your design.•You may use any found material.•The container must be 8” x 8” x 8”.•Hold a Large Egg (teacher supplied day of testing).•Must be able to touch the egg from each side.•The lightest design that keeps the egg from cracking will earn 100 points•If the egg cracks, you will earn 70 points max.•Drop from 3rd floor to Commons.

Explanation

5. Explore possibilities.• Review the Problem –• Review the ideas you came up with –• Review your research (that is why you did it)• Review the criteria –• Come up with at least 3 different ideas

– These are sketches with annotations!

Now it is your turn.

Explanation

6. Select an approach-• Use a Decision Matrix.• This is a Table

– Criteria along the top– Possible solutions along the left side– Use your ideas to complete this table.

This is a sample of how it should work

In the event of a tie – give weight to the “more important” criteria

Explanation

•Create an argument on why your design is the best solution to the problem or why it is not. •This argument must be based on logic, facts, and data. •A valid argument also provides the facts and data for the opposing argument. •Your argument must be well written and make use of the references from your research

Explanation

7. Develop a design proposal• You will need to create a Multi-view drawing of

your best solution.• Make sure that you include dimensions and

other important information.• Some solutions may be complex and need

many drawings to build from.• What you design here is what you will build and

ultimately test.

Explanation

8. Make a model or prototype. • Once you have made your initial solution,

take a picture of it.

Explanation

9. Test and evaluate the design.

• You will need to create a test for your solution.

• Some projects may be destroyed after testing, so you might want to come up with non-destructive tests.

• Create a table to record your test results.

10. Redesign. • As you test your solution, you will make

changes based on the results of the test.• Take pictures of these changes.

Explanation

11. Create or make it.• This is your final solution to the design.• Take a picture of the final solution.• Video you testing the final solution

12. Communicate processes or results

• Explain what you did during this project• Imagine that you have 2 minutes to tell the

class what you did and how you solved the problem.

• Or explain why your solution did not solve the problem.
