ENGINEERING DESIGN PROCESS

Engineering Design Model - Steps1.INVESTIGATION AND

RESEARCH

2.GENERATION OF SOLUTIONS

3. DEVELOPMENTAL WORK

4.PROTOTYPE DEVELOPMENT

5.TESTING

6.EVALUATION AND REDESIGN

Investigation and Research

•Most important step•Problem Identification•Different Angles and Perspectives

ENGINEERING DESIGN MODEL

• Parameters and constraints• AVOID- solving symptoms of problems

and not the problem

INVESTIGATION AND RESEARCH

Generation of Solutions•As Many solutions as possible•No wrong answers •Think outside the box

ENGINEERING DESIGN MODEL

Development Work•Evaluate and decide on solution and design• Cost • Shape• Aesthetics• Ergonomics• Safety • Etc.

ENGINEERING DESIGN MODEL

Prototype Development

• Create model/ makeup of your design

• Follow blueprint • Full scale vs. Scaled

down?• Does the Design Solve

the Problem?

ENGINEERING DESIGN MODEL

ENGINEERING DESIGN MODEL

Testing:

• Does this prototype / Design Solve the problem?

• Is it the best possible solution?

• Can it be redesigned to : • Cheaper• Lighter• Stronger• Material selction

Evaluation and Redesign•Did development and testing create new ideas or direction?•Is this the best possible solution to the problem?

ENGINEERING DESIGN MODEL

•Ergonomically design a mouse prototype for a selected target population• Sketch• Target population

information• Prototype – styrofoam• present
