Criteria or Constraints_TECH

What stage of the design process would you first specify and identify the criteria and constraints of need or problem? (*red line on diagram)

• Concept Stage

• Development Stage

• Evaluation Stage

Leonardo da Vinci was an engineer and artist. His notebooks included his personal notes and observations along with drawings and diagrams for designing a flying machine.

Criteria or Constraints: Should need to lift off the ground and actually fly

• Criteria

• Constraints

Thomas Edison used his notebooks to prove his mathematical theories and to show his thought process throughout the creation of his many inventions, like the incandescent light bulb.

Criteria or Constraints: Should need to be bright, safe, and last a long time

• Criteria

• Constraints

Thomas Edison used his notebooks to prove his mathematical theories and to show his thought process throughout the creation of his many inventions, like the incandescent light bulb.

Criteria or Constraints: had to think about the cost of materials and how easy it would be for people to use the light bulb

• Criteria

• Constraints

Nikola Tesla was an inventor and a scientist. His engineering notebooks included a wide range of entries

including creation of the alternating current (AC) system, which is a way to send electricity over long distances.

Criteria or Constraints: should be safe, work over long distances, and be more efficient than the existing direct current (DC) system

• Criteria

• Constraints

Nikola Tesla was an inventor and a scientist. His engineering notebooks included a wide range of entries

including creation of the alternating current (AC) system, which is a way to send electricity over long distances.

Criteria or Constraints: had to make sure the system was not too expensive and that it could be built with the technology available at the time

• Criteria

• Constraint

For the design team in their design brief to solve the mountain bike problem: Must be a part of the bike, not an add-on
