THE DESIGN PROCESS
INFORMED DESIGN
SPECIFICATION:
PERFORMANCE REQUIREMENT THAT THE DESIGN MUST MEET
CONSTRAINT:
LIMIT IMPOSED ON A DESIGN SOLUTION
Finished dragster can’t be longer than
12 inches.
It must be made out of the bass wood block.
How much finished product can cost
What kind of material must be used
Time available for production
STEP 1:
Find out what the specifications and
constraints are
RESEARCH THE PROBLEM
IDENTIFYTHE PROBLEM
Ask questions
STEP 1:IDENTIFY THE PROBLEM FIGURE OUT WHAT THE PROBLEM IS
STEP 2:
SPECIFICATION:
CONSTRAINT:
PERFORMANCE REQUIREMENT THAT THE DESIGN MUST MEET
LIMIT IMPOSED ON A DESIGN SOLUTION
What are the specifications and constraints?
RESEARCH THE PROBLEM
STEP 2:
RESEARCH THE PROBLEM
SALESALE
INTERNET BOOKS/ LIBRARY
SURVEY
MARKET RESEARCH
How does the weight of a dragster affect its speed?
What is drag, and how does it affect the speed of the dragster?
How could you reduce the amount of drag on your model?
How will the force of friction affect your model?
WHAT KINDS OF RESEARCH QUESTIONS DID WE ASK
FOR OUR DRAGSTER DESIGN PROBLEM?
STEP 3:
THINK OF ALTERNATIVE DESIGNS
STEP 4:
CHOOSE and JUSTIFY the BEST DESIGN
PICK THE BEST SOLUTION:
THE ONE THAT BEST MEETS THE SPECIFICATIONS
STEP 5:
DEVELOP A PROTOTYPE (OR SCALE MODEL)
FULL-SIZE WORKING MODEL OF THE SOLUTION PROTOTYPE:
SCALE MODEL:
MAY BE SMALLER OR LARGER THAN FINAL PRODUCT
STEP 6: TEST and EVALUATE the DESIGN SOLUTION
COLLECT PERFORMANCE DATA TO SEE HOW WELL THE DESIGN MEETS THE SPECS
Dragster Performance
STEP 7:
REDESIGN
(IF NECESSARY)
Back to the drawing board!
EXAMINE YOUR DESIGN CRITICALLY
LOOK BACK AT THE DESIGN SPECS
