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.

© GIT20

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

© GIT25

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

© GIT27

Information in Design

• Receive– TV/Cellphone/Ipod– Websites – Management– Journals– Colleagues – Students

• Process – Analysis– Synthesis

• Transmit– Drawings– Documents– Presentations (Design Reviews)

© GIT28

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?

© GIT29

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?
