Ask
What is the main objective of the "Ask" step in the engineering design process
To clearly define the problem and identify its requirements and constraints.
Which activity best describes the "Imagine" step of the engineering design process?
Listing as many creative ideas as possible without judgment
During the "create" step, what is the primary purpose of building a prototype?
To test and evaluate the design solution.
What is the primary purpose of testing a prototype?
To evaluate how well the prototype solves the original problem and meets the design criteria.
What is a key activity performed during the planning step?
Developing design drawings and considering potential failure points.
Which question is NOT essential to ask during the "Ask" step?
What materials will I need to build a prototype?
True or False: In the "Imagine" step, it's a good practice to only brainstorm practical and easy-to-build ideas.
False
Which of the following is an essential activity during the creation of a prototype?
Taking detailed notes and recording observations in an engineering notebook.
What is the iterative nature of the engineering design process, particularly during testing, most accurately described as?
A cyclical process of testing, finding problems, redesigning, and retesting.
Which of the following best describes the function of design requirements during the planning step?
They are the criteria and constraints that the final solution must satisfy.
What is a "constraint" in the context of the "Ask" step?
A limitation or restriction on the design, such as budget, materials, or time.
The "Imagine" step follows which other steps in the engineering design process?
C. Ask and Research
What is the next logical step after building and programming a prototype?
Testing and evaluating the prototype.
A team tests a new water filtration device and finds that users are confused about how to replace the filter. Which question does this result most directly address?
"Does the user interact with the solution exactly as intended?".
Considering risks is an important part of the planning step because it allows engineers to
Anticipate and mitigate potential problems before building.
When defining the problem, a good practice is to make the problem statement
Quantifiable and specific
In your own words, what is the main goal of the "Imagine" step?
The main goal is to think creatively and generate a large number of different possible solutions to the identified problem. This involves brainstorming as many ideas as possible without dismissing any of them prematurely.
A team is constructing a prototype of a new backpack. Which of the following is an appropriate action for this stage?
Fabricating a working model from available, potentially less expensive, materials.
During the testing phase, a team finds that their prototype for a new sneaker does not meet the specified requirement for durability. What should the team do next?
Go back to an earlier step of the design process, such as refining the design, to address the durability issue
Negative criticism of ideas is an important part of brainstorming during the planning step.
FALSE
During the "Ask" step, what are the three core questions an engineer should ask to define the problem?
Why is it important to generate a large quantity of ideas during the imagining stage, even if some seem far-fetched?
Generating many ideas increases the chances of discovering a unique, effective, or truly innovative solution that might not have been obvious at first. Some of the most creative solutions can come from seemingly "wild" or non-traditional ideas.
What is the term for a restriction or a limitation placed on a design, such as cost or available materials?
Constraint.
What is the next logical step after a working prototype is built?
Test the prototype under controlled conditions and record results.
During the planning step, which of the following is the primary goal?
To select the most promising solution and prepare for its creation.
