Engineering Design Process

Question 1

Step 1: Identify the Problem

Answer 1

Students state the challenge problem in their own words. For example: How can I design a ______________ that will ____________?

Question 2

Step 2: Identify the Criteria and Constraints

Answer 2

Students specify the design requirements (criteria) and limits on the design due to available resources and the environment (constraints).

Question 3

Step 3: Brainstorm Possible Solutions

Answer 3

Each student sketches his or her own ideas as the group discusses ways to solve the problem. Drawings should be qiuck and brief but should include labels and arrows.

Question 4

Step 4: Generate Ideas

Answer 4

Each student develops two or three ideas more thoroughly and creates neat, proportional drawings with parts and measurements labeled. Drawings should be orthographic projections and isometric drawings.

Question 5

Orthographic projections

Answer 5

multiple views showing the top, front, and one side

Question 6

Isometric drawing

Answer 6

three-dimensional depiction

Question 7

Step 5: Explore Possibilities

Answer 7

Team members share and discuss developed ideas and record pros and cons next to the drawings.

Question 8

Step 6: Select an Approach

Answer 8

Students work in teams to identify the design that appears to solve the problem the best. Students write a statement that describes why they chose that solution and include some reference to the criteria and constraints.

Question 9

Step 7: Build a Model or Prototype

Answer 9

Students construct a full-size or scale model based on their drawings.

Question 10

Step 8: Refine the Design

Answer 10

Students examine and evaluate their prototypes/models based on the criteria and constraints. Groups may enlist students from other groups to review the solution and help identify changes that need to be made. Based on criteria and constraints, teams must identfy any problems and proposed solutions.

Question 11
