DESIGN METHOD REVIEW
• STARTS WITH A PROBLEM
• ENDS WITH A SOLUTION
• CYCLICAL IN NATURE
• ALL STEPS MUST BE WELL DOCUMENTED
DEFINE THE PROBLEM
•NEED STATEMENT
• WE NEED TO LAUNCH A GOLF BALL AS FAR AS POSSIBLE.
BACKGROUND RESEARCH
•TWO QUESTIONS NEED TO BE ANSWERED:
1.
WHO ARE THE USERS?
2. WHAT SOLUTIONS ALREADY EXIST FOR THIS PROBLEM?
SPECIFY REQUIREMENTS
• WHAT CHARACTERISTICS WILL A SUCCESSFUL SOLUTION HAVE?
• USE YOUR BACKGROUND RESEARCH TO HELP.
• THE MORE DETAILED YOUR LIST, THE EASIER TO CHOOSE A
SOLUTION IN THE NEXT STEP.
BRAINSTORM, EVALUATE, AND CHOOSE
• BRAINSTORM-
• QUANTITY OVER QUALITY
• EVALUATE-
• FEASIBILITY:
• FUNCTIONALITY:
• CHOOSE-
• COMPARE EVALUATED SOLUTION LIST TO CHARACTERISTICS LIST
DEVELOP AND PROTOTYPE SOLUTION
• PROTOTYPE-
• PHYSICAL ROUGH DRAFT
• WORKING MODEL
• FINAL PRODUCT WOULD BE MORE USER FRIENDLY,
MADE FROM BETTER MATERIALS, AND MORE
AESTHETICALLY PLEASING
TEST SOLUTION
• TWO POSSIBLE OUTCOMES:
1.
SOLUTION MEETS REQUIREMENTS• PRODUCT IS FUNCTIONAL, READY FOR DEVELOPMENT INTO MARKETABLE GOOD
2.
SOLUTION MEETS REQUIREMENTS PARTIALLY OR NOT AT ALL
1.
PARTIALLY- PERFORMED PART OF TASK, OR PERFORMED TASK POORLY
2.
NOT AT ALL- NO PART OF TASK PERFORMED
COMMUNICATE RESULTS
•FINAL REPORT- OVERVIEW OF YOUR PROCESS
•SHOULD INCLUDE THE FOLLOWING:
• SYNOPSIS OF BACKGROUND RESEARCH
• MATERIALS USED
• EXPERIMENTAL PROCEDURE
• DATA ANALYSIS
• FUTURE DEVELOPMENTS AND IMPROVEMENTS
• CONCLUSIONS
VOCAB!!!
• PROBLEM- A SITUATION OR ITEM THAT DOES NOT WORK THE WAY WE WANT IT TO
• PROTOTYPE- A WORKING MODEL THAT CAN BE TESTED
• REQUIREMENTS- CHARACTERISTICS THAT THE SOLUTION MUST HAVE TO BE SUCCESSFUL
• EVALUATE- TO DETERMINE WORTH, FUNCTIONALITY, AND FEASIBILITY
• SOLUTION- AN IDEA OR INVENTION THAT CORRECTS THE PROBLEM
LET’S GET STARTED!!!
1. DEFINE THE PROBLEM
2. DO BACKGROUND RESEARCH:
• TYPES OF CATAPULTS• HOW DID THEY WORK
• WHAT WERE THEY USED FOR
• WHAT ADVANTAGES DID THEY HAVE OVER OTHER TYPES
