Engineering Design: Design Process, Ergonomic & Materials

A technology company has identified the need for a smaller laptop computer that weighs less, but they do not have enough knowledge about how to build it. 
What would be the next logical step engineers would take to design and produce this laptop computer?

• Build a new type of laptop battery
• Research current laptop technology
• Build a prototype computer

An emergency-equipment company makes warning-signal flares. The company wants to redesign  a flare so that it produces light for a longer period of time. 
After the company thinks of ideas, what is the next step in the design process?

• Build a prototype
• Define the problem
• Decide on the best solution

Some scientists want to design a system of instruments that will evaluate ocean currents, temperatures, and winds in order to predict weather patterns. 
What should they do before they produce the first complete working version of the system?

• Improve the design of the system
• Evaluate the results of the system
• Build a prototype of the system

A factory produced a new type of refrigerator designed to use less electricity. The machine was manufactured and sold to the public at Target, Wal-Mart, and K-Mart. After several months, reports showed that this refrigerator was not working correctly. 
Which choice below is the most likely cause?

• The proper cost analysis was not performed.
• The designers did not test other types of machines.
• They did not rigorously test and modify the prototype
