Pointers for Success
• Do’s– act professionally – follow instructions– be in class & studio on time– use the tools that are
presented– read the book– give professional
presentations– follow procedures (safety)– clean-up in studio– report damaged equipment
• Don’t’s– miss class– close your minds to the
alternatives – sleep in class– bring food into studio– leave a mess in studio.

Attendance
• Studios:– Missing a studio results in a 0 for that studio grade– No way to make up a missed studio the next week
• Lectures– Missing an In-class quizz scores 0 – no make-up
possible– Missing a lecture irrevocably results in you being a
loser for the day
1. Most of your work is done as part of a team.
2. Missing lecture requires your teammates to educate you.
3. That is not their job.
4. There are only 16 lectures.

Reality Check
• This course is about– problem solving – considering alternatives– organization– writing– presenting– getting a taste of the real world
• Professionalism– projects– reports– attendance– deadlines

?? Creative Decisions and Design ??

Design Problem Solving
• Analysis– What needs to be done– What do current products do– What are the necessary functions
• Develop Alternatives– Many, many alternatives
• Decision Making– Picking the Best Among
Alternatives• Information Processing
– Sketches to CAD Drawings– Drawings to Parts– Parts to Assembly

Characteristics of Design
• Multi-stage process• Large quantities of information• Many supporting design tools - analysis,
optimization, simulation, etc. • Uncertain path to solution (Not just 1 solution)• Alternatives, revisions, versions, updates…• Iterative and cyclic• Multidisciplinary• Teamwork - interactions between engineering &
business management

Information in Design
• Receive– TV/Cellphone/Ipod– Websites – Management– Journals– Colleagues – Students
• Process – Analysis– Synthesis
• Transmit– Drawings– Documents– Presentations (Design Reviews)

Questions to Continually 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?– How are changes in technology affecting the
marketplace?
-

Building Machines
• How can our product be made?– What manufacturing processes can/must be
used?• How can we make the product for less?
– Can we use less expensive material or processes?
– Can we simplify the design? (cycle back to design)
• How long will it take to make our product?– Will we make it to market on time?– Will we make it in time for the ME2110 contest?
