What is the main purpose of the "Ask" step?
To define the problem and the goals for the project.
What is the purpose of the "Test" step?
The purpose of the "Test" step is to determine if the prototype successfully meets the original problem's criteria and constraints.
What is the difference between criteria and constraints in the engineering design process?
Criteria are the project's goals and requirements, while constraints are the limitations.
What is the primary purpose of the "Plan" step in the engineering design process?
To select a single solution and create a detailed plan for it
What worked well during the testing phase?
The parts of the prototype that performed as intended, such as a specific material, a successful mechanism, or a feature that met a user need.
What is a "constraint" in the context of engineering design?
A limitation or restriction, such as budget, materials, or size.
What should be included in the testing plan?
A testing plan should include every step of the testing procedure, all safety precautions that were taken, and should explain how the solution is expected to work, based on research.
Which of the following is an example of a design criterion for a new backpack?
It must be able to hold at least three textbooks. This is a functional requirement for the design.
During the "Plan" step, an engineer develops a detailed sketch. What should this sketch include?
A detailed drawing of the design and the materials to be used
What did not work as expected?
Any parts that failed, performed poorly, or did not function as designed, such as a weak joint, a slow reaction time, or a feature that was difficult to use.
A limitation or restriction, such as budget, materials, or size.
This helps engineers understand the need they are trying to meet before designing a solution.
What is the primary goal when evaluating the results of a test?
The primary goal of evaluation is to draw conclusions based on the data collected during the test.
Which of the following is an example of a design constraint for a new backpack?
It must be less than 20 inches tall. This is a limiting factor on the design.
Which of the following activities occurs during the "Plan" step, but not before it?
Choosing a single solution to develop further
The results of tests, such as measurements, observations, and feedback, that indicate how well the prototype meets the design's objectives.
What types of questions are asked during the "Ask" step?
Questions about the problem, the desired outcome, the user, the requirements, and the limitations (constraints).
What is a possible outcome if the prototype fails the test?
If the prototype fails the test, the next step is to redesign and improve the solution.
When writing a Product Design Specification (PDS), the purpose is to:
Outline the requirements, criteria, and constraints for the design project.
After brainstorming solutions in the "Imagine" step, what is the immediate next action taken in the "Plan" step?
Choosing the best solution to move forward with
What specific changes need to be made to improve the design?
A detailed list of revisions, such as changing a material, redesigning a part, or adding a new component.
What is one key question to ask about the project's success?
"What are the project requirements?" or "What are the criteria for success?".
How are safety precautions addressed during the testing phase?
If the prototype fails the test, the next step is to redesign and improve the solution.
What is a trade-off in the context of balancing criteria and constraints?
A compromise made by sacrificing one design aspect to meet another.
Why is it important to include a list of materials in the detailed plan before building a prototype?
It ensures that the materials are available and helps in the planning of the construction of the prototype.
How will these revisions address the problems identified during testing?
An explanation of how the proposed changes will solve the problems identified during testing.
