Design

• Standard 8
• Students will develop an understanding of the
  attributes of design.

1. Everyone can design solutions to a problem.
2. Design is a creative process.
3. The design process is a purposeful method of
   planning practical solutions to problems.
4. Requirements for a design include such factors as
   the desired elements and features of a product or
   system or the limits that are placed on the
   design.

Design

• Standard 8 continued 6-8

1. Design is a creative planning process that leads
   to useful products and systems.
2. There is no perfect design.
3. Requirements for a design are made up of criteria
   and constraints.

Design

• Standard 8 continued 9-12

1. The design process includes defining a problem,
   brainstorming, researching and generating ideas,
   identifying criteria and specifying constraints,
   exploring possibilities, selecting an approach,
   developing a design proposal, making a model or
   prototype, testing and evaluating the design
   using specifications, refining the design,
   creating or making it, and communicating
   processes and results.
2. Design problems are seldom presented in a clearly
   defined form.
3. The design needs to be continually checked and
   critiqued, and the ideas of the design must be
   redefined and improved.
4. Requirements of a design, such as criteria,
   constraints and efficiency, sometimes compete
   with each other.

OK, What about BME Design?

• What is so special about us?
• Input
• Output
• Content
• , then ERC matters

The Knowledge Triangle Design
15
Design Is

• Verb conceive, invent, to formulate a plan for
  devise, to have as a goal or purpose intend
• Noun A drawing or sketch especially a detailed
  plan for construction or manufacture, the
  purposeful arrangement of parts or details, the
  art or practice of making designs, an ornamental
  pattern, a plan or project, or a reasoned
  purpose intent.

The Design Course _at_ VU

• Lecture 2.5 months
• Projects (industry, faculty, other, 5 mo.)
• Product (catheter, database, pacifier )
• Process (C_at_ clinic, Oral Surgery clinic)
• Unusual (Softball, C. Elegan, Heart Fiber)
• Grand Challenge (Capstone Design)
• Oral, written, poster, device as output

17
What is different about BME Design?

• Why not combine BME, EE, ME, ChE, CSE in a big
  design pot?

18
Answers

• It is done has value
• Potential for a complete prototype is improved
• Mimics real life
• When do you do the BME specific lecture material
  how do you guarantee BME topics?
