improve
did the prototype meet all the design criteria and measurable targets
analyze the test data to see if the prototype performed as expected if targets were missed identify which specific metrics fell short and by how much
What specific materials, tools, and equipment are necessary to build the prototype?
The engineering design process is best described as:
b) A flexible, iterative process used to develop solutions to problems
What is the fundamental need or problem to solve?
A clear, concise statement defining the problem. For example, "Students need a better way to organize their lockers to reduce clutter and find items quickly".
What is the problem we are trying to solve?
A single, clear, and concise statement defining the problem or need identified. For instance, "Students need a better way to carry their lunch".
what parts of the design performed well and what failed during testing
Clearly identify and document which features were successful and which were problematic. This allows the team to prioritize redesign efforts on the weakest areas.
Are all necessary resources available and within the project's budget?
An assessment of resource accessibility and a confirmation that costs align with financial limitations. The plan should account for potential shortages and budget restrictions.
What does it mean for the design process to be iterative?
c) That it involves repeating steps, such as testing and redesigning, until an optimal solution is found.
Why is this problem important to solve?
Who is the end-user, and what do they need?
An answer should specify the target audience and their needs. For example, "Elementary school students need a durable, easy-to-open lunchbox that will not crush their food."
How did the prototype perform under conditions more severe than the standard use case?
A robust design should function reliably even in harsh or unusual conditions. Testing beyond the normal parameters can reveal weaknesses and opportunities for reinforcement.
What skills and expertise are required to execute the plan?
an outline of the technical knowledge and practical skills needed by the team to successfully build and test the prototype
What is the first and arguably most important step in the engineering design process?
d) Defining the problem
What was intended to happen versus what is happening now?
A description of the current, suboptimal conditions based on observations or data.
How can the design be simplified to reduce the number of parts or steps?
An elegant solution is often the simplest one. Reducing complexity can lower costs, minimize potential points of failure, and streamline the manufacturing process
What are the measurable criteria for success, and how will the design meet them?
Which of the following is an example of a constraint in the design process?
c) The materials for a project cannot exceed $50. (A constraint is a limitation, while a criterion is a measure of success
Who is the problem affecting?
Did users interact with the solution in the way it was intended?
Observe user behavior. If users are doing things differently than you expected, understand why. This can indicate flaws in the design or reveal new insights into user behavior that can be incorporated into the next iteration
Which of the brainstormed ideas will be selected and why?
In the brainstorming phase, what principle is most important to follow?
b) Encourage creativity and avoid criticizing any ideas
Who are the other stakeholders involved, and how will this solution impact them?
