Engineers go through a process usually over and over until they get their solution exactly as they want it.
True
False
Juan is going to design a kite. After doing research, Juan creates several different designs and selects the one he wants to use. What are the next two steps Juan should do in the design process?
build a prototype and test it
build and finish full-sized kites
patent the design and sell it
What determines if you need to redesign your prototype?
Did people like it?
Did it meet some or none of the requirements of the criteria and constraints?
Did I brainstorm enough?
Is it to safe to build?
Two students were building a small helicopter together. They attached blades to the top and made them spin. They then released the prototype helicopter from the top of a building to watch it fly. Which step of the engineering process were they working on?
Design
Test
Improve
Share
In some cases prototypes need changes and modifications with each iteration. What is the meaning of the word iteration?
To repeat
To eat the prototype
To leave it
To share it
What is the criteria?
a limitation or restriction that must be followed by the designer
group problem solving process
the task the design must meet/what it must accomplish
What are constraints?
a limitation or restriction that must be followed by the designer
group problem solving process
set of measurable standards or specifications the design must meet
A technology company has identified the need for a smaller laptop computer that weighs less, but they do not have enough knowledge about how to build it.
What would be the next logical step engineers would take to design and produce this laptop computer?
Design a new type of laptop battery
Research the structure of existing laptops
Build a prototype computer and test it
An emergency-equipment company makes warning-signal flares. The company wants to redesign a flare so that it produces light for a longer period of time.
According to the engineering design process, after the company generates ideas based on their research, what should they do next?
Build a prototype
Define the problem
Choose an idea
What two things determine whether or not engineering solutions are successful?
If it stays within the constraints
If it looks cool
If everyone voted it to be the best
If it meets the criteria
Which word best describes a constraint?
criteria
justification
limitation
goal
