engineering design process

engineering design process

  • Define the Problem
  • Do Background Research
  • Specify Requirements
  • Brainstorm Solutions
  • Choose the Best Solution
  • Do Development Work
  • Build a Prototype
  • Test and Redesign


  • innovation and design process
  • technical design and construction
  • teamwork


build something that will move a ping pong ball across the room


  • object cannot touch the floor
  • object cannot be moved across the room by an individual (no throwing)
  • only use the materials given
  • one individual from each team is designated by the team to perform the task during testing


  • you may only use materials from this list
  • plastic spoon
  • ping pong ball
  • 20 rubber bands
  • 2 meters of masking tape
  • scissors (for construction)


  • 20 points if your teams ping pong ball travels 5 ft
  • 20 points for the teams design that travels the longest distance


("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation

the things that are created by engineering individually or collectively that solve an identified problem and usually the technology is developed to make a task easier, simpler, or more efficient

intended benefits

the problem a technology was meant to solve or the task it was meant to accomplish, or make easier

what the technology was built for


unintended consequences

a negative effect of a particular technology that wasn't planned for

unintended benefits

a positive effect of a particular technology that wasn't planned for


cost (consequences) benefit analysis

all technology has at least one unintended consequence, no technology, no matter how valuable and needed, is perfect

as a society we have to decide, do the benefits outweigh the costs of new technologies and is there a way to mitigate (reduce) or eliminate the unintended consequences

engineering design process

once engineers have sorted out the benefits and consequences of a particular technology, they redesign the technology to mitigate (reduce) or eliminate the unintended consequences of the technology

coal power plant

commuter trains

search engines

air conditioners



application of engineering to living things, such as humans and plants, is called bioengineering

bioengineered technologies can be classified as either assistive or adaptive

assistive technologies

assistive technologies are developed to help organisms without changing them

adaptive bioengineered technology

adaptive bioengineered products change the living organism
