Introduction to Biomedical, Industrial and Human Factors Engineering©2014 Joe TritschlerDepartment of Biomedical, Industrial & Human factors EngineeringWright State University • Dayton, OhioWhat is Engineering?• Engineers apply principles of math & science to solve technical problems.• The non-negotiable laws and forces of nature are directed by engineers to meet humanneeds.• Engineering is the application of science & math to solve technical problems and create new systems, products, or devices to benefit civilization.ABET’s Definition:“Engineering is the profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind.”(ABET = Accreditation Board for Engineering and Technology; the accreditation organization for college and university programs in math & science, including yours!)The Technological Team• Scientists• Engineers• Technologists• CraftspersonsScientists & Engineers• Scientists ask “why?”• Engineers ask “what can I make with it?”• Scientists want to understand why our world behaves the way it does.• Engineers apply scientific principles to solve problems and meet human needs.• Scientists emphasize the theoretical.• Engineers apply established scientific theories and principles to create new products or solvetechnical problems.Engineers• Engineers are the link between scientific theory and the implementation of technology.• The end result of science is new knowledge.• The end result of engineering is design.• Design is a creative process that results in a new device, system, structure, or process that satisfies a specific human need.Technologists• Have basic training in science, math, and engineering.• Usually not at the same depth of level as the engineer; but this isn’t always the case.• Trained in manual skills to implement ideas of engineers - test, troubleshoot, reduce, and record data.Craftspeople• Practical implementers of products.• Possess skills to operate machinery and fabricate and construct parts.• Train through an apprenticeship.• Skilled in industrial arts - welding, electrical wiring, construction, plumbing.• Create molds & dies, operate lathes & mills, and make electronic circuit boards.• Engineers and scientists are lost without technologists and craftspeople!“Common Traits of Good Engineers”• According to Engineering Fundamentals 4thEdition by Moaveni, good engineers– are problem solvers– have a firm grasp of the fundamental principles of engineering, which they use to solve many different problems– are analytical, detail oriented, and creative– have a desire to be lifelong learners– have good written and oral communication skills– have good time-management skills– have good “people skills”– are adept at using computers– are good at working in team environments• Discussion topic: list three engineering developments over the last 1,000 years that have solved problems in order to meet human needs and benefit mankind and civilization. Now list three that may not have benefitted society, mankind, and
