  1. Concept Generation Integrated Product and Process Design ME 475

  2. Fall Schedule P. 26 Guidebook

  3. Fall Assignments P. 35-62 Guidebook

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

  5. Structured Design Process… Mission Statement Development Plan Identify Customer Needs Establish Target Specifications Generate Product Concepts Select Product Concept(s) Test Product Concept(s) Set Final Specifications Plan Downstream Development Perform Economic Analysis Benchmark Competitive Products Build and Test Models and Prototypes Documentation Moving forward in the Design process; from What to How… Integrated Product and Process Design

  6. 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 lotsof ideas….. (Speaking of BBQ’s...) Integrated Product and Process Design

  7. The Essence of Engineering is Design… Apollo 13 Example

  8. 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

  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….

  10. Concept Generation… Four Principles • What existingconceptsmight be adapted for our application? • What new conceptsmight 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

  11. OK, So What is A Concept? A Concept (or sub-concept) is: • An approximate description of the technology, working principlesandform 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 besatisfied… • 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

  12. Concept Generation Process… • Clarify the problem… • Problem Decomposition • Search externally… • Lead Users • Experts • Patents • Literature • Benchmarking • Search internally… • Individual Methods • Group Methods • Explore Systematically… • Classification Tree • Combination Table • Reflect on the Process and its results… Clarify Problem Search Internally Search Externally Explore Systematically Reflect on Process Integrated Product and Process Design

  13. Concept Generation Process • Clarify the problem • Problem Decomposition • Search externally • Lead Users • Experts • Patents • Literature • Benchmarking • Search internally • Individual Methods • Group Methods • Explore Systematically • Classification Tree • Combination Table • Reflect on the Process Clarify Problem Search Internally Search Externally Explore Systematically Reflect on Process Integrated Product and Process Design

  14. Clarify the Problem:Power Nailer Example… Integrated Product and Process Design

  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 Design 12

  16. 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 ablack 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

  17. Problem Decomposition: Function Diagram for Nail Gun Step 1 NOTE: verb- noun pattern Step 2 Note 7 sub- functions Integrated Product and Process Design

  18. 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… Integrated Product and Process Design 51

  19. Function Decomposition: Wheelchair Note 4 sub- functions Integrated Product and Process Design

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

  21. Sub-Functions and sub-Concepts…

  22. Concept Generation Process • Clarify the problem • Problem Decomposition • Search externally • Lead Users • Experts • Patents • Literature • Benchmarking • Search internally • Individual Methods • Group Methods • Explore Systematically • Classification Tree • Combination Table • Reflect on the Process Clarify Problem Search Internally Search Externally Explore Systematically Reflect on Process Integrated Product and Process Design

  23. Lead Users benefit from improvement innovation source Benchmarking competitive products Related/unrelated products Experts technical experts experienced customers Patents search related inventions Literature technical journals trade literature Search Externally:Hints for Finding Related Solutions Integrated Product and Process Design

  24. Capture Innovation from Lead Users:Utility Light Example Integrated Product and Process Design

  25. Search Externally: Benchmarking Competitive Products…….. Integrated Product and Process Design

  26. Search Externally: Benchmarking Integrated Product and Process Design

  27. Search Externally:unrelated/related products Hardware stores, Sears……. e.g. gripping function, etc. Integrated Product and Process Design

  28. Search Externally: Unrelated Products Do these products have anything in common? Integrated Product and Process Design

  29. Both Doors Snap Closed… The train car inspired the cam design that closes the battery door on the Palm Treo Dock Integrated Product and Process Design

  30. Search Externally: Getting help from experts… • Experts in the field - Within your company - Other companies (vendors) • Faculty and researchers at universities • Other Integrated Product and Process Design

  31. 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 • www.uspto.gov • www.google.com/patents • Law Library: Ask for help at reference Desk or visit BYU Technology Transfer Office (west side of Lee Library) Integrated Product and Process Design

  45. 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
