Unit 1.6 Engineering Design Process

Rosa is trying to make a new mug that keeps beverages warm and which costs under $2.00 per mug. She makes a table while studying two materials that are being considered for the mug. Rosa chooses the better insulating material, which is also the most expensive. This drives the cost up to $2.25 per mug. Which statement explains Rosa’s decision to go with the more expensive material?

• She is making a tradeoff by selecting the ceramic material.

• She is making a tradeoff by selecting the plastic foam material.

• She is trying to increase the profit for the company that makes the mugs.

• She is paying attention to the constraint by selecting the best material for the product.

What is the final step in optimizing a design solution?

• Brainstorm ideas for a design.

• Make improvements to the design.

• Select a design, build, and test a model.

• Decide whether the design meets the criteria and constraints.

What is the role of brainstorming in the design process?

• To finalize the design.

• To generate a variety of ideas.

• To test the design.

• To reduce the number of ideas.

William thinks the design of his go-cart is too heavy and needs to be lighter. He comes up with a number of solutions and evaluates the constraints and criteria. One of his main constraints that affected most of his solutions was cost. Which next step would be the best one for William to take in order to solve this problem?

• Make models for all the solutions and test them.

• Try to raise money to build and test all the solutions.

• Go back to the drawing board and start a new design.

• Choose a solution and make a model based on that choice.

The goal of engineering is to develop solutions for human needs. A group of people tests the same four pest control products using the same methods. Testers achieve the same results. Why might the testers disagree about which of the four pest control solutions is best?

• They might use the products in different ways.

• They might use the products for different lengths of time.

• They might have had different outcomes with the products.

• They might weigh risks and benefits of each solution differently.

      Engineers are designing a water bottle to be used by hikers. Which statement describes a tradeoff in the design of the water bottle?

• Using metal instead of plastic

• Choosing only three colors for production

• Making it heavier for durability

• Adding a large opening for easy filling

When designers make compromises during the engineering design process, the result is often:

• additional criteria

• more constraints

• increased efficiency

• a trade-off

What is the main purpose of building a prototype?

• To test ideas and identify problems before building the real thing

• To use up leftover materials

• To create the final product

• To show off engineering skills
