Engineering Design Process
This is the first step in the engineering design process, when engineers identify what needs to be solved.
What is identifying a need?
This is the use of tools, materials, or processes to meet human needs.
What is technology?
This analysis compares the unfavorable effects of a decision or technology with its favorable effects.
What is risk-benefit analysis?
This test model of a product helps engineers try out a design.
What is a prototype?
This field aims to construct explanations about the natural world.
What is science?
Engineers do this after identifying a need and before brainstorming solutions.
What is conducting research?
Technology is developed to meet these.
What are people’s wants and needs?
A technology may be worth using when its benefits are greater than these.
What are the risks?
This chart is used to compare features of multiple items.
What is a Pugh chart?
This field uses scientific and mathematical knowledge to solve practical problems.
What is engineering?
This skill helps engineers come up with original ideas during the design process
What is creativity?
Trees, grass, and flowers belong to this world, not the designed world.
What is the natural world?
This analysis examines the materials and energy used to manufacture, transport, sell, use, and dispose of a product.
What is life cycle analysis?
When comparing technologies, engineers examine each of these.
What are the features?
The goal of engineering is to address these.
What are the needs of society?
These three broad kinds of skills are needed for engineering design: research, technical, and these.
What are thinking skills?
This includes structures, environments, and products people use every day.
What is the designed world?
A technology can have effects that are expected or unexpected, and these two kinds of effects.
What are favorable and unfavorable effects?
Engineers use this model to test a product idea before deciding on a final design.
What is a prototype?
Science and engineering have different goals: science explains the natural world, while engineering designs solutions to meet these.
What are human or societal needs?
Put the engineering design steps in order: research; communicate results; build a prototype; identify a need; test, evaluate, and redesign; brainstorm and select solutions.
What is identify a need, conduct research, brainstorm and select solutions, build a prototype, test/evaluate/redesign, and communicate results?
Nature can inspire engineers. The design of a submarine, for example, may be inspired by the movement and shape of this animal.
What is a salmon?
A community accepts a technology’s possible risks in exchange for its benefits. This decision reflects this idea: accepting risks to gain benefits or giving up one benefit to gain another.
What is a trade-off?
Engineers compare several possible designs with a chart, build a test version of their strongest idea, then use test results to improve it. Name the chart and the test version.
What are a Pugh chart and a prototype?
A team skips research and brainstorming, then immediately builds a device. Name two parts of the engineering design process the team skipped.
What are conducting research and brainstorming/selecting solutions?
