A team is told to suggest as many ideas as possible without criticism. What technique is this, and why is it important in design?
Brainstorm; because it stimulates creative thinking and allows for a wide range of potential solutions to be considered.
Assessment; because it evaluates the effectiveness of each idea.
Criteria; because it sets the rules for which ideas are acceptable.
Constraint; because it limits the number of ideas generated.
A team must design a product within a set budget and using specific materials. How should they handle these requirements?
By identifying and working within the constraints to ensure the design is feasible.
By ignoring the constraints and focusing only on creativity.
By only considering the appearance of the product.
By letting each team member work independently without guidelines.
Why is a design brief important in solving complex problems, and how does it help in engineering planning?
It provides a written plan that identifies the problem, criteria, and constraints, encouraging comprehensive thinking before attempting a solution.
It only describes the final product without considering the problem.
It focuses solely on the aesthetic aspects of the design.
It eliminates the need for any further documentation.
How do criteria and constraints help in the design process?
They help narrow solutions to those that best meet needs and requirements.
They limit creativity and prevent new ideas.
They are only used after the solution is made.
They are optional and do not affect the outcome.
A student needs to evaluate a prototype's performance against goals and criteria. What approach should be used, and why is it valuable in engineering design?
Assessment; it allows for systematic evaluation and improvement by analyzing trade-offs and determining the best course of action.
Brainstorming; it focuses on generating new ideas without evaluation.
Design Statement; it only describes what the solution should do.
Designer; it refers to the person, not the process.
A company adds a new user-friendly feature to an existing smartphone. Which term best describes this process, and why?
Innovation, because it involves improving an existing product.
Invention, because it creates something that never existed before.
Prototype, because it is a model used for testing.
Product, because it is a tangible artifact.
Engineers are testing and improving a water filter until it works as needed. What best describes this process and why?
Iterative, because it involves repeating steps to achieve the desired outcome.
Justifiable, because it is based on accepted standards.
Research, because it involves studying materials.
Piling-on, because it adds new ideas.
What should a student provide to show their experimental results are valid?
The results are well-founded on evidence and match the real world.
The results are based on a new idea.
The results are in chronological order.
The results are made by a machine.
A designer makes a full-scale model of a new bicycle to test and improve it. What is this model called, and why is it important?
Prototype, because it allows for testing and adjustments before final production.
Product, because it is a tangible artifact.
Invention, because it is a new process.
Engineering Notebook, because it documents the process.
In a brainstorming session, if someone suggests an idea that improves another person’s idea, what is this process called?
Piling-on, because it produces a similar or enhanced idea.
Problem Identification, because it recognizes a problem.
Research, because it studies sources.
Justifiable, because it is reasonable.
