Reality Check (1) This course is about

– understanding alternatives– problem solving– organization– writing– presenting– getting a taste of the real world

Professionalism– projects– reports– attendance

Reality Check (2) Do’s

– follow instructions– be in class on time– be in studio on time– pay attention– use the tools that are

presented– read the book– give professional

presentations– act professionally– follow procedures (safety)– clean-up in studio– report damaged equipment

Don’t’s– miss class– turn in hand written reports– give hand written

presentations– close your minds to the

alternatives– sleep in class– bring food into studio– leave a mess in studio.

Attendance You must attend all studios

– missing a studio results in a 0 for that studio grade

You must attend all lectures– attendance will be taken at 9:20 AM– being late is 0.5 of a missing lectures– we will be using a seating chart– there are only 14 lectures– missing lectures (rounded down) will result in a final grade penalty

2-3 missed lectures = 1 letter grade reduction 4-5 missed lectures = 2 letter grade reduction 6-7 missed lectures = 3 letter grade reduction 8-9 missed lectures = 4 letter grade reduction

Science and Engineering Scientific Method

– Science is theory corrected by experiment– Predicts the world

Engineering Method– Application of scientific principles to solve problems– The ordered sequence of steps used

to describe engineering design in engineering problem solving

– Incorporates the use of engineering heuristics heuristic reasoning logical, ordered, and systematic procedure plan for solving engineering problems

– Changes the World

Characteristics of Design

Multi-stage Large quantities of data Supporting design tools - analysis, optimization,

simulation, etc. - in various design phases Uncertain design path Alternatives, revisions, versions Iterative and cyclic Teamwork - interactions between designers Multidisciplinary Dynamic

Questions to Ask When Designing Where can I sell my product?

– What products do my customers need?

How can I improve my product?– What customer needs are not being met?

When will my product become obsolete orinappropriate?

– How are changes in technology affecting the marketplace?
