Objectives for Today: OK—now 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 Product and Process Design 4 (Speaking of BBQ’s...)
The Essence of Engineering is Design… Apollo 13 Example
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….” “Don’t let fear of failure discourage you…” President Dieter F. Uchtdorf 8
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….
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
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 device—or 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 Design 9

Clarify the Problem: Power Nailer Example… Integrated Product and Process Design 11
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 Design 12
Clarify The Problem (cont’d) 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… Integrated Product and Process Design 13
Problem Decomposition: Function Diagram for Nail Gun NOTE: verb- noun pattern Integrated Product and Process Design 14 Step 1 Step 2 Note 7 sub- functions
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…
Function Decomposition: Wheelchair Integrated Product and Process Design 15 Note 4 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. Plant—genetically engineered living things Two reasons for patent law(Intellectual Property-IP) Web patent search sites Law Library: Ask for help at reference Desk or visit BYU Technology Transfer Office (west side of Lee Library) Integrated Product and Process Design 22

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
