2. Laura A. Gerold, PEWhat is a PE? 3. Laura A. Gerold, PE What
is a PE (Professional Engineer)? To become licensed, engineers must
complete a four-year college degree, work under a Professional
Engineer for at least four years, pass two intensive competency
exams and earn a license from their states licensure board. Then,
to retain their licenses, PEs must continually maintain and improve
their skills throughout their careers (NSPE). 4. Laura A. Gerold,
PEWhat is a PE? Only a licensed engineer may prepare,sign and seal,
and submit engineeringplans and drawings to a public authorityfor
approval, or seal engineering work forpublic and private clients
(NSPE). 5. What does Laura actually do? I am a water resources
engineer at Tetra Tech. What is a water resources engineer? 6. What
does Laura actually do? I am a water resources engineer at Tetra
Tech. What is a water resources engineer? Concerned with the use
and control of water. I work on projects mostly to do with rivers
and pipes, such as river restoration, storm and sanitary sewer
design, etc. Example Projects Rexnord Floodwall in Milwaukee KK

Language for Design(Chapter 1) 32. Technical Drawing Used to
communicate ideas Universal Language Takes teamwork to put together
a set of drawings Technical Drawing are drawn by Engineers
Architects Drafters Designers Manufacturers Technicians 33.
TECHNICAL DRAWINGTechnical drawings serve one of three purposes:
Visualization Communication Documentation (Courtesy of
Seymourpowell.) (Courtesy of Woods Power-Grip Co., Inc.)(Courtesy
of Dynojet Research, Inc.) 34. Technical Drawing Example
Professions that use technical drawings Civil Engineering
Mechanical Engineering Electrical Engineering Architecture
Bio-resource Engineering Landscape Design Industrial Design
Construction Engineering & Technology Patternmaking Project
Management Fabrication Manufacturing 35. Why draw by hand? Small
Projects Back and forth exchange of ideas (Concept Drawings)
Engineer Client Engineer Mark-up Final Refining Consensus Building
Better understanding of how to draw 36. Artistic vs. Technical
Drawings Artistic drawings are used to express
aesthetic,philosophic, or other abstract ideas. Technical drawings
are functional drawings torepresent the design of objects to be
built orconstructed 37. Computer-Aided Design and Product
DevelopmentComputer Aided Design (CAD)Computer Aided Engineering
(CAE)Computer Aided Manufacturing (CAM)CAD allows for a range of
activities, frommodeling 2D and 3D geometry to creatingdrawings
that document the design formanufacturing and legal
considerations.CAE allows users to simulate and analyze structures
that will be subject to various temperatures, staticloads, or
fluctuating loads.CAM provides computerized control for
manufacturing processes. 38. Drawing Example Blocks! 39. Design
Process1. Problem identification: First, a clear statement of the
need for and objectives for the design must be written.2. Ideation
(Concepts and Ideas): Technical sketches are often used to convey
concepts to multidisciplinary teams.3. Refinement/analysis
(Comprise Solutions): Designs may be rethought, based on
engineering analysis. CAD models and sketches are useful during the
analysis and compromise stage. Accurate 2D or 3D CAD models and
drawings are created to refine the design.4.
Implementation/documentation (Creation of Models & Prototypes):
Production and/or working drawings providing the details of
manufacture and assembly are finalized and approved. 40.
ENGINEERING DESIGN STAGE 1Identify the Customer and the ProblemThe
engineering design process beginswith recognizing or identifying
theseneeds and considering the economicfeasibility of fulfilling
them. A successful design must not only solvethe problem but also
meet the needs andwishes of the customer. (Project developed and
created by Philips Design.) 41. ENGINEERING DESIGN STAGE 2 Generate
ConceptsDuring this stage, often called the ideation stage, many
ideasreasonableand otherwiseare collected.The ability to freely
createtechnical sketches lets youpresent and share ideas andrecord
them so you can referto solutions, inspirations, andbreakthroughs
that come tolight during this creative stageof the process.
(Courtesy of Seymourpowell.) 42. ENGINEERING DESIGN STAGE
3Compromise SolutionsThe design teamselects various featuresof the
conceptsgenerated in theideation stage andcombines them into oneor
more promisingcompromise solutions. 2D CAD Drawing. (Courtesy of
Seymourpowell.) Many of these problems are solved graphically,
using schematic drawings in which various parts are shown in
skeleton form. For example, pulleys and gears are represented by
circles, an arm by a single line, and a path of motion by
centerlines 43. ENGINEERING DESIGN STAGE 4 Models and Prototypes
Design teams often construct a model to scale to study, analyze,
and refine a design.3D CAD Model. This 3D CAD model of a design for
the Mars rover was constructedto act as a virtual prototype for the
design. (Courtesy of Byron Johns.)3D CAD Model of the SAAR Brake.

5Production or Working DrawingsThe drawings, showing thenecessary
views, includethe material, dimensions,required tolerances,
notes,and other informationneeded to describe eachpart sufficiently
for it to bemanufactured consistently.These drawings of
theindividual parts are alsoknown as detail drawings. Detail
Drawing for the SAAR Brake Air Can Mounting Bracket. (Courtesy of
Dynojet Research, Inc.) 45. Design Process Activity The design
process helps engineers, technicians, and otherproblem-solvers come
up with creative solutions. You arean engineer. Choose ONE
engineering problem below, andfollow apply the design process steps
to invent asolution. A. Your new pet kitten is trapped in a ten
foot deep hole. Youneed a contraption to safely rescue your poor
animal. B. You are going on vacation for a month and cant
findanyone to water your plants while youre gone. You need adevice
that will give your plants the right amount of water not too much
and not too little. C. You like to read before you go to sleep, but
you dont have abedside lamp. You need a way to turn off the light
switchacross the room without having to get out of bed. 46.
Evaluation and Extension: 1. What problem did you choose?
Brainstorm ways tosolve the problem and list several possible
solutions. 2. Choose one idea. Draw a detailed picture of
thesolution you chose. Label the drawing to explain whateach part
is made out of, how the parts fit together,and how it will work. 3.
Where do you think you will run into problems withyour solution?
Where do you think the weak parts inyour creation will be? 47.
Concurrent EngineeringTraditionally, design and manufacturing
activities have taken place in sequentialorder rather than
concurrently (simultaneously). This step-by-step approachseems
logical, but in practice it has been found to be wasteful.
Concurrent engineering is a systematic approach that integrates the
design and manufacture of products with the goal of optimizing all
elements involved in the life cycle of the product.The Concurrent
Process 48. Life Cycle DesignLife cycle design means that
allaspects of a product (such as design,development, production,
distribution,use, and its ultimate disposal andrecycling) are
consideredsimultaneously.The basic goals of concurrentengineering
are to minimize productdesign and engineering changes and toreduce
the time and cost involved intaking a product from design
conceptthrough production and ultimately tointroduction into the
marketplace. 49. Assembly DrawingsAn assembly drawing, shows how
all the parts go together inthe complete product. Assembly Drawing

DRAFTING STANDARDSThere are standards that support a uniform,
effective graphic language foruse in industry, manufacturing,
engineering, and science.In the United States, providing
thesestandards has been the work of theAmerican National Standards
Institute(ANSI) with the American Society forEngineering Education
(ASEE), theSociety of Automotive Engineers (SAE),and the American
Society of MechanicalEngineers (ASME).International standards,
often defined bythe International Organization forStandardization
(IOS), and the ASME orANSI standards for drawing practices
aresimilar in many respects.
