1. Introduction to Biomedical Engineering Design
Chapter 1
Original author: Paul King Presentation modified by Karen Schuyler

2. What is Design? Is NOT research or craftsmanship!
Involves devices, processes, re-engineering, systems, optimization, regulations, finances, innovation, invention, entrepreneurship, etc.

3. Design Verb: invent, intend, devise

Noun: drawing, arrangement, pattern, plan, art of making designs

4. For What Uses Might Products be Designed?
Class discussion on what types of products they thing would be good candidates for design.

5. Basic but Essential Questions

What?
Where?
When?
Why?
How?
Their Job?
Well, yes, but also……..
Your Job

7. Design: National Academy of Science
Product refers to hardware, service, or mission.
Process refers to the means by which a product is manufactured and supported
Development refers to the refinement of products and processes to correct problems. (Re-engineering, sometimes reverse engineering, …)
National Academy of Sciences:

8. Design: NAS Mission requirements analysis/Product system strategy
- high level engineering analysis
- requirements definition

9. Design: NAS Product specification - product strategy
- voice of the customer!!!
(QFD, etc.)
- environment (EPA) & regulatory (FDA!!!)
- planned product specification

10. Design: NAS Concept development
- target setting (cost, schedule, performance, etc.)
- brainstorming on product & process alternatives
- development of product and process concepts.

11. Design: NAS Preliminary Product and/or Process design
- high level definition of product and process designs
- evaluation of same v. targets
- high level system trade-offs

12. Design: NAS
Refinement & verification of detail product and process designs
- development of designs for components, subsystems & manufacturing
- Geometry creation
- prediction & evaluation of attributes
- tracking & trade-offs
Sound from

13. Design: NAS System Prototype Development
- experimental evaluation of attributes that do not meet target values
Preparation for production
- refine process for manufacture
Production, Testing, Certification, Delivery
Operation, support, decommissioning, disposal

15. Generic Design – 13 Experts Concept Map

16. Design as taught in BME272 @ Vanderbilt

17. Other Design Concerns Retracing if problem is ill defined
Excessive documentation
Human patients, animal studies, permissions
Design is often iterative
Delving into already patented info bases
Teamwork, finances, reality
