  1. If you can remember seven passwords to get into your computer to do your job but forget your second wedding anniversary, you could be an engineer. Mei-Chuan S Haverkamp

  2. Chabot College Presentation11/19/13 Jim Haverkamp Senior (Ancient) Mechanical Engineer

  3. Disclaimer • In this presentation I am going to mention some of the things that has molded me into the engineer that I am. • My mold is only one of many and just because you don’t exactly fit in my mold does not mean that you cannot become an outstanding engineer. • Saying the word “engineer” is like saying vehicle, the next question is usually “What kind?”

  4. History • From a young age I have always been intensely interested in how things worked. • I would get excited when thing broke • This would extend to my toys • This became such an obsession that I would actually weigh the difference between having the toy and finding out how it worked • Finding out how it worked usually won • I got to be good with the disassembly process

  5. My mother labeled me the worlds most destructive kid in the world!

  6. Why Mechanical? • Found in the basement as an old TV that was not working. • I plugged it in and confirmed that it, in fact, was not working properly. • Before I did anything I unplugged to. “Can’t be too careful, right?” • I took the back off and was immediately in heaven! • I discovered capacitance! • Cleaned up

  7. United States Navy • When in the Navy I was eventually assigned to R division. R is for Repair. • Take thing apart • Put them back together • The are supposed to work • When on a ship at sea one cannot run to the local Osh store. • Have to make out own tools and I became very interested in tool design and why. • Leaving the navy I found work in the sheet metal industries.

  8. Education • Chabot College (Los Positas) 1982 – 1986 • UC Berkeley 1986-1989

  9. Digressing just a bit • Part of the reason I left the navy is that I objected to being forced to wear a uniform like everybody else • I went from this …..

  10. To this …..I think I lost that round

  11. The following are sanitized slides from and actual project that I ranPhase 1 is to produce a conceptual design • The first step is to clarify the objective • What is causing the need? Some function that does not meet a requirement. • What is the scope of the problem? • When is a solution needed? • What is the budget? • The second step is to create a specification that I will design to. • Finally I will come up with some conceptual designs and demonstrate how they fulfill the specifications

  12. Product / Project Name / Date of Review / Name of Presenter • XXXXXXXX Window Pry tool, 3/7/13, Jim Haverkamp • Objective of this Design Review • Obtain permission to purchase newly designed pry tool XXXXXXXXX and test fixture • Identify EPL Item Driving This Activity • PR XXXXXXXX • Problem statement • The XXXXXXX tool has two windows that stick together due to adhesion from the two O-rings. A tool is needed to pull the windows apart. • Previous tool does not fit well and requires the removal of several parts • Earlier tool failed after 4 uses

  13. Project Objective • Specifications • Pry the top window from the bottom window • During the removal the gas distribution plenum with remain attached to the top window • Material from the tool will not contaminate or damage either window • Will not require the removal of the Plastic alignment brackets that are attached to the pinnacle • Cost - Targeting $1260 • Time / Schedule • Design complete 2/28/13 • Receive parts 3/11/13 • Release 3/15/13 • Success Criteria • Confirmation that will provide 2X the force or the XXXXX before failure on the upper window • Confirmation that it will perform equally as well as the XXXXX1 on the lower window • Scope • 10 customers currently own a this tool including our lab. Potential need for the tool is between 20 and 30. • This tool is not legacy, there is a potential for more customers • Summary of Design Change • Tool foot designed to fit into gap between the two windows • Material changed from polycarbonate to 40% glass filled polycarbonate • SS Helicoil changed to Nitronic 60 gall resistant Helicoil • An Aluminum plug insert is designed to provide support for the polycarbonate • Frame members were thickened to aid in managing the load

  14. This is the part that I designed

  15. The part in position

  16. Addition specifications that I found during the design process

  17. Finite Element Analysis was used to confirm that the part could match the forces

  18. Example of a risk table

  19. Phase 2 involves buying parts and breaking them!

  20. Take notes and document lessons learned • During the breaking phase there is nearly always a surprise or two that requires redesign. • Question your results! In this case the Finite Element Analysis was bit applicable • Review and update risks

  21. Phase 3 get it ready for a customer • Lock down the design • Create a Bill of Materials (BOM) • Create instruction on how to use it or install it • What to do with the old parts • MONITOR CUSTOMER FEEDBACK!!!!! Be proactive! • When the customer returns with positive feedback ….

  22. After positive feedback Go Kayaking and have a beer In that order!
