Objectives for Today: OKnow that we have discussed how to
identify the Whats, (i.e. Customer Needs and resulting Functional
Specs.), how do we best come up with possible Hows to meet those
needs and specifications? Summary 4 Need a BBQ Grill?

Concept Generation Creating and developing concepts (and
sub-concepts) involves one of the most fulfilling and uplifting
aspects of engineering design Research has shown that the best way
to have a really good idea is to have lots of ideas.. Integrated

Creation Brings Fulfillment The desire to create is one of the
deepest yearnings of the human soul.Creation brings deep
satisfaction and fulfillment. We develop ourselves and others when
we take unorganized matter [and create something]. Creation means
bringing into existence something that did not exist before. Dont
let fear of failure discourage you President Dieter F. Uchtdorf

Slide 9
Structured Design Process The Concept Generation portion of the
design process stresses not setting our minds on a specific
solution, at first instead, our efforts should yield a number of
alternatives for later evaluation.
Slide 10
Concept Generation Four Principles What existing concepts might
be adapted for our application? What new concepts might satisfy our
key customer needs and specifications? What methods can be used to
facilitate the generation of concepts? How can I increase my
creativity? Integrated Product and Process Design 7
Slide 11
OK, So What is A Concept? A Concept (or sub-concept) is: An
approximate description of the technology, working principles and
form of an idea, device, or process A description of how the device
(or portions of the deviceor process), might work so that what the
customer needs and wants might be satisfied Usually defined (at
first) by a sketch and a textual description A concept may be made
up of a number of sub- concepts Integrated Product and Process

Slide 15
Clarify the Problem: Nail Gun We translate Key customer needs
into metrics & target values, which results in product
specifications The nail Gun: - Accommodates Nail lengths from 50 to
75 mm - Provides maximum nailing energy of 80 joules/nail -
Provides a nailing force up to 2,000 newtons - Can nail at rate of
up to 1 nail/second - Can insert nails between standard stud/joists
(368 mm-14.5 inches-opening) - . Integrated Product and Process

Clarify The Problem (contd) Problem Decomposition: Functional
(or other) decomposition -Step 1, Think of the device, (product, or
process) we are going to create as a black box -Step 2, Divide the
black box into sub-functions, each sub-function contributing to
what the total product, (or process) will do. End result is a
function diagram containing sub- functions categorized into types

Step 2 Note 7 sub- functions
Slide 18
18 Integrated Product and Process Design 51 Once we note sub-
functions (using a verb noun pattern of thinking), our mind will
more readily think of ways-- hows (sub- concepts) to accomplish
these sub-functions

Individual Exercise: Take 4 Minutes: - Quickly list four
sub-functions for your project using chart handed out at beginning
of class - Identify three sub-concepts that might accomplish just
one of these needed sub-functions - Tape the chart in your
Guidebook - Be prepared to share your results with the class

Search Externally: Finding Ways to Achieve Functions from
Patents Three types of patents 1. utility--describes how a device
or method works. Generally most helpful! 2. design--describes the
look or form of a device 3. Plantgenetically engineered living
things Two reasons for patent law(Intellectual Property-IP) Web

Reflect on the Results of the Process and the Process Are we
pleased with the results we have obtained? Is the team developing
confidence that the total solution space has been fully explored?
Should we consider alternative function or decompositional
diagrams? Are there alternative ways to decompose the problem? Have
external sources been thoroughly pursued? Have internal ideas from
everyone been accepted for consideration and integration into the
process? Integrated Product and Process Design 55
