Design & Modeling Lesson 3 Review

A design team is working on creating a new energy-efficient light. They have completed the following steps: - They asked questions, did research, and determined the design requirements for their solution. - They brainstormed, sketched their ideas, compared them, and identified the best possible solution to pursue. - They created detailed technical drawings, including CAD drawings, to use to produce their solution. What is the next step of the design process that they should complete?

• Develop and Test Solution

• Present the Solution

• Evaluate Solution

• Design a Solution

Which of the following behaviors can negatively impact team success?

• Group members listen to each other and everyone’s ideas are heard

• Group members feel free to disagree, but all feedback given is helpful

• Group members focus on the ideas of those with the best grades in the class.

• Group members understand their tasks and help each other achieve the goals

Which of the following best describes why sketching is an effective communication tool?

• Designers can color parts of a sketch to show texture and communicate an object’s appearance

• Sketching allows designers to accurately communicate details of their ideas with lots of information at once

• Using sketches to communicate ideas makes the design neat and pleasing to the eye

• Sketching tells a story about the design, such as how it might be used or where it will be made

Which sketch might a designer or engineer use to communicate their design with dimensions?

• A perspective sketch

• A multiview sketch

• An isometric sketch

• A thumbnail sketch

• 2.194 in.

• 2.200 in.

• 2.294 in.

• 2.940 in.

Use the image to answer the question. What is the length of the three blocks (to the line)?

• 3.5 cm

• 3.5 in.

Why is a decision matrix an important tool to use in the design process?

• A decision matrix is used to identify the criteria, constraints, and deliverables

• A decision matrix organizes your sketches, models, and brainstorming

• A decision matrix determines the best solution by comparing design ideas to the criteria and constraints

• A decision matrix is a contract between the client and the designer

Engineers, scientists, and designers innovate products by taking apart existing products and observing and documenting how they work, to determine how they can be improved. What is this process called?

• Statistical analysis

• Mechanical dissection

• Mathematical modeling
