Engineering Design Process - Paper Airplanes
Transcript of Engineering Design Process - Paper Airplanes
1. Identify the problem
2. Research the problem
3. Develop possible solutions
4. Choose Best Solution
6. Test and Evaluate
5. Build a model or prototype
8. Refine & Redesign
My paper airplane doesn't fly very far
and dives to the ground.
Redesign the airplane
to allow better lift.
Create different plans.
Create a paper airplane
with wider wings for better lift.
If the paper airplane still drops to quickly, or doesn't fly far enough, then redesign plans to allow for farther flying.
Get paper and fold the paper according to design.
Find an open area and throw plane a measured distance.
Learn about Bernoulli's Principle and how airplanes fly.
Redraw plans with clear instructions, measurements and dimensions. Give plans to a friend and have friend test paper airplane.
The engineering design process involves a series of steps that lead to the development of a new product or system.
The first step involves locating a common problem with something designed, or one that you are experiencing.
Example: How can I design
a __________ that will __________?
Here you need to learn all you can about the topic you chose, how it is designed and the history of its use.
Discuss possible ideas that could make the design better. Think of how science and math can be applied to make your improvements.
You should develop two or three ideas more thoroughly. You could create new drawings or sketches, or write out a proposal that would describe how you would make your improvements.
Once you choose the best solution to your problem, you should write a statement that describes why you chose the solution. This should include some reference to the how it solves the problem and what possible new problems you may face.
You should construct a full-size or scale model based on your drawings. You should also identify and acquire appropriate modeling materials and tools.
Testing out your model is important to be able to be sure that your ideas are working and that you actually solved the problem your are attempting to work with.
You should communicate with others about your design improvements to see what others think and what impacts there may be on different levels.
You will need to examine and evaluate your prototypes or designs based on the criteria and constraints.
Identify any problems, then you redesign your plans and rebuild your prototype to see how things have changed and any improvements that have been made.
