Title: Center for Engineering Science in Design: combining innovative engineering research and education


1
Center for Engineering Science in Design
combining innovative engineering research and
education
  • Derek Dunn-Rankin
  • Mechanical and Aerospace Engineering Department
    Henry Samueli School of Engineering
  • University of California, Irvine

MAE Department Potential Research Areas
  • Aerospace Guidance, Navigation and Control
    (Mease)
  • We are currently developing atmospheric guidance
    algorithms for space transportation vehicles and
    a new control mechanism for missiles and
    uninhabited air vehicles, including a flight
    demonstration. Previous research has addressed
    aircraft flight control, hypersonic vehicle
    guidance, low-thrust orbit transfer, satellite
    attitude control, and Kalman filter based
    navigation.
  • MEMS sensors and actuators (Shkel)
  • We are developing novel sensors and actuators
    which can be implemeted using lithography based
    batch fabrication techniques (similar to CMOS
    technology). The motivations are a potential for
    significant cost reduction without sacrifice in
    performance, and an opportunity for enabling new
    applications where sensor/actuator' small
    dimensions are critical. We design/model,
    fabricate, and characterize all devices we
    develop using in house facilities. Our current
    projects include strategic grade
    single-crystal-silicon (SCS) capacitive
    gyroscopes on-a-chip, navigate grade chip scale
    atomic gyroscopes, piezoresistive SCS linear and
    angular accelerometers for 10,000 g applications,
    and 6H-SiC pressure sensor for harsh environments
    (0.1 Full Scale PSIA in  -65 C to 600 C).
  • Fluid powered robots for human rehabilitation
    (Bobrow, Reinkensmeyer)
  • We are developing pneumatically actuated robots
    for the rehabilitation of both gait and arm
    motions.  Our approach requires nonlinear control
    of compressible air flow in order to develop
    machines that extend human capability and are
    safe to work with. These machines use at least 10
    servovalves which are all controlled in a
    coordinated manner to achieve safe,
    high-bandwidth control of force output.
  • Fluid powered actuators for structural shock and
    vibration attenuation (Jabbari, Bobrow)
  • We are creating a new class of semi-active shock
    isolation devices (using Parker cylinders) that
    quickly damp structural vibration without
    transmitting severe shock loads.  These devices
    have successfully in damped vibrations in
    full-scale test structures subject to earthquake
    load conditions.
  • Nozzles and sprays (Dunn-Rankin, Samuelsen,
    Sirignano, Rangel)
  • We maintain a world-class research program in
    the design of nozzles for spray delivery and in
    the characterization of liquid and gaseous
    sprays, including jet fuel and molten aluminum.

Intellectual Property Issues
4
Licensing
  • Reimburse UC for patent costs
  • Ensure diligent commercialization
  • Pay a license issuance fee
  • Pay a royalty on net sales
  • Accept provisions covering indemnification

5
Is there another way?
  • The UC system is unlikely to lead a revolution in
    intellectual property relationships with
    for-profit companies
  • Use of consulting option may allow some
    flexibility
  • Under circumstances where the primary product is
    human resource development (e.g., training
    engineers) the intellectual property issues can
    be minimized in good faith relationships

Industry/University Collaborative Research
  • Motivations
  • Industry research topics are VERY interesting and
    match well with faculty expertise
  • Provides financial support for student
    researchers
  • Shared interest in human resource development
  • Excellent fundamental engineering education
  • Realistic problem solving
  • Ability to translate theory to practice
  • Challenges
  • Industry action horizon versus academic year
  • Publishable fundamentals versus functional
    solutions
  • Intellectual property ownership
  • Faculty often lack systems viewpoint
  • Engineering Science in Design
  • Platform for research and education

    Fluid Mechanics, Solid Mechanics, and Systems
    Theory.
  • Plan
  • Engineering Design, and Engineering Design in
    Industry.
  • Execute
  • Independent Research, and Engineering Project
    Development

PDCA Cycle clarity of information is key to

PDCA (or Shewart) Cycle originally developed by
Walter Shewhart, of Bell Laboratories in the
1930's.

It was promoted from the 1950s by the Quality
Management authority, W. Edwards Deming, and is
consequently known by many as the Deming Wheel'.

Engineering Justification (Define Analyze)
Engineering judgments are conclusions or
decisions obtained from engineering analysis and
are not the same as personal opinions, insights
or ideas. The justification of an Engineering
judgment is generated using experience and
training as an Engineer .
  • An Engineering justification document consists of
    the following items
  • Goal -- specify the goal of the decision process.
  • Requirements -- define the physical properties,
    performance, cost, delivery and other
    constraints.
  • Technical Issues -- define the scientific
    principles underlie the manufacture, operation or
    other features of the system or components that
    are the focus of the decision process.
  • Evaluate Alternative -- identify three
    alternatives and evaluate the benefits and
    concerns.
  • Select and Demonstrate -- select an alternative.
    It must match requirements, and be chosen based
    on complexity, reliability, manufacturability,
    price, delivery or other specified criterion.
    Demonstrate the successful implementation of the
    alternative in the system model.
  • Impact -- specify the impact of the selection on
    remaining design decisions for the system.

14
Science in Design
  • Common Features
  • Small groups
  • Mentored by one or two faculty
  • Open ended problem
  • Guide the connection between theory and design
    decisions
  • This is not enough
  • Groups cannot self-organize
  • Decisions must be verified at this stage
    pattern matching returns
  • Center Approach is
  • Organize student teams
  • Consistent expectation/documentation of
    individual effort
  • Realistic design problem and external judges
    (industry sponsor, experts, scientific peers
  • Prevent pattern matching solution methods,
    particularly during execution/verfication
  • Define, Analyze, Execute, Verify
  • Graduate and industrial research matches this
    model

15
