What’s so important about all ofthis stuff?
•People of every generation all aroundthe world have increased theircapability to do work and live well byinventing and innovating.
•The development of any kind oftechnology is a human activity and isthe result of someone having a problem,needing something new to fix theproblem, and creating a solution.
•Invention requires a lot of patience andperseverance.
•Technology is closely linked to creativity,which has resulted in innovation.
•Invention is a process of turning ideasand imagination into devices and systems.
What’s so important about all ofthis stuff (continued) ?
•Innovation is the process of modifying anexisting product or system to improve it.
•Innovation often involves decreasing theoverall capabilities of a product orsystem in order to increase its ability toperform a more narrow or specific taskvery efficiently. This process is calledspecialization of function.
What’s so important about all ofthis stuff (continued) ?
•New products and systems can bedeveloped to solve problems or to help dothings that could not be done without thehelp of technology.

Engineering DesignProcess
The steps in the processinclude:
–Defining the challenge
–Explore ideas
–Plan & Develop
–Test idea
–Present the solution
Prototypes
•A prototype is a full-sizeworking model used to testa design.
•Prototypes are often usedin the automobile industryto develop new car andtruck ideas to their fullestpotential while carefullyevaluating the designs’strengths and weaknesses.
Working in groups of 3 or 4,you will use the engineeringdesign process to invent anew Candy Dispenser.
